(n) decreased or increased, as applicable, by any other amount provided for elsewhere in this Agreement or otherwise agreed upon by Seller and Purchaser, to the extent not offsetting any Current Assets or Current Liabilities of the Company, as applicable, included in the Effective Time Net Working Capital;

provided that, in calculating the adjustment to the Unadjusted Purchase Price pursuant to this Section 2.3, no adjustment may be accounted for in more than one of the paragraphs above.

Section 2.4 Closing Cash Payment and Post-Closing Purchase Price Adjustments.

(a) Not later than five (5) Business Days prior to the Closing Date, Seller shall prepare and deliver to Purchaser a settlement statement (the “Closing Settlement Statement”) calculating the amount equal to the Cash Purchase Price as adjusted to give effect to Seller’s good faith estimate of the adjustments provided for in Section 2.3 based upon the best information available to Seller (or, if then determinable, the final amounts thereof), together with reasonable documentation in support of such calculation. Purchaser shall have three (3) Business Days to review the settlement statement and submit a written report containing any changes Purchaser proposes to be made to the settlement statement. Seller and Purchaser shall agree on a final settlement statement prior to Closing; provided, however, if Seller and Purchaser are unable to agree, then, subject to Section 2.4(b), Seller’s good faith determination shall be used for purposes of the Closing Cash Payment to be made at the Closing. The calculation delivered by Seller in accordance with this Section 2.4(a), as adjusted in accordance with the immediately preceding sentence, if applicable, less the Deposit, less (if applicable) the Disputed Amount and the Additional Escrow Amount paid into the Defect and Indemnity Escrow Account at Closing, shall constitute the dollar amount to be paid by Purchaser to Seller at the Closing (the “Closing Cash Payment”).

(b) No later than the later of (i) one hundred twenty (120) days following the Closing Date or (ii) the resolution of all Disputed Matters pursuant to Section 6.7 and Exhibit D, Seller shall prepare and deliver to Purchaser a draft statement (the “Post-Closing Statement”) setting forth the final calculation of the Cash Purchase Price taking into

26

account any adjustments pursuant to Section 2.3 (including the calculation of each adjustment pursuant to each paragraph of Section 2.3), together with reasonable documentation in support of such calculation. As soon as reasonably practicable but not later than the thirtieth (30th) day following receipt of Seller’s statement hereunder, Purchaser shall deliver to Seller a written report (an “Adjustment Notice”) containing any changes Purchaser proposes be made in such statement. The Parties shall undertake to agree on the final Cash Purchase Price no later than thirty (30) days after delivery of the Adjustment Notice. If the final Cash Purchase Price is:

(i) mutually agreed upon by Seller and Purchaser during such thirty (30)-day period, the final Cash Purchase Price shall be conclusive and binding on the Parties.

(ii) not mutually agreed upon by Seller and Purchaser during such thirty (30)-day period, then Seller or Purchaser may require for Houston, Texas office of KPMG (the “Dispute Auditor”) to resolve any disagreements. Should KPMG fail or refuse to agree to serve as Dispute Auditor within ten (10) days after written request from any Party to serve, and the Parties fail to agree in writing on a replacement Dispute Auditor within five (5) days after the end of that ten (10) day period, or should no replacement Dispute Auditor agree to serve within fifteen (15) days after the original written request pursuant to this sentence, the Dispute Auditor shall be appointed by the Houston, Texas office of the American Arbitration Association. In connection with the engagement of the Dispute Auditor, each of Seller and Purchaser shall execute such engagement, indemnity and other agreements as the Dispute Auditor shall require as a condition to such engagement. The Dispute Auditor shall determine as promptly as practicable, but in any event within thirty (30) days after the selection of the Dispute Auditor, based solely on written submissions provided by Purchaser and Seller to the Dispute Auditor (and without independent investigation on the part of the Dispute Auditor) within ten (10) days following the Dispute Auditor’s selection, whether and to what extent (if any) Seller’s statement requires adjustment. In resolving any disputed item, the Dispute Auditor shall act as an expert and not an arbitrator, and shall resolve only the items set forth in the Adjustment Notice that are still in dispute and may not assign a value to any item greater than the highest value for such item claimed by either Seller or Purchaser or less than the lowest value for such item claimed by either Seller or Purchaser. The costs of the Dispute Auditor shall be borne evenly between Seller and Purchaser. The determination of the Dispute Auditor shall be final, conclusive and binding on Purchaser and Seller. The date on which the final Cash Purchase Price is finally determined in accordance with this Section 2.4(b) is referred to as the “Determination Date.”

Any difference in the Closing Cash Payment and the final Cash Purchase Price shall be paid by the owing Party to the owed Party within fifteen (15) Business Days of the Determination Date. Any post-Closing payment pursuant to this Section 2.4 shall bear interest from the Closing Date to the date of payment at the Agreed Rate.

27

(c) Purchaser shall assist Seller in preparation of the Post-Closing Statement of the Cash Purchase Price under Section 2.4(b) by furnishing invoices, receipts, reasonable access to personnel and such other assistance as may be requested by Seller to facilitate such process post-Closing.

(d) All payments made or to be made under this Section 2.4 by either Seller or Purchaser shall be made by electronic transfer of immediately available funds to the bank(s) and account(s) specified by the receiving Party in writing.

Section 4.7 Financing. At Closing, Purchaser will have sufficient cash, available lines of credit or other sources of immediately available funds (in United States Dollars) to enable it to pay the Closing Cash Payment to Seller at the Closing (“Financing”). Purchaser Parent has, and at Closing will have, sufficient duly authorized shares of its common stock to enable it to issue the Purchaser Parent Shares to Seller.

Section 4.8 Investment Intent. Purchaser is an “accredited investor” as such term is defined in Rule 501 promulgated under the Securities Act. Purchaser is familiar with investments of the nature of the Acquired Membership Interests, understands that this investment involves substantial risks, has adequately investigated Seller, the Company, the Company Assets and the Acquired Membership Interests, and has substantial knowledge and experience in financial and business matters such that it is capable of evaluating, and has evaluated, the merits and risks inherent in purchasing the Acquired Membership Interests, and is able to bear the economic risks of such investment. Purchaser has had the opportunity to visit with Seller or its Affiliates and meet with its officers and other representatives to discuss the business, assets, Damages, financial condition, and operations of the Company, has received all materials, documents and other information that Purchaser deems necessary or advisable to evaluate the Acquired Membership Interests, and has made its own independent examination, investigation, analysis and evaluation of the Acquired Membership Interests, including its own estimate of the value of the Acquired Membership Interests. Purchaser has undertaken such due diligence (including a review of the properties, Damages, books, records and contracts of the Company and Seller) as Purchaser deems adequate. Purchaser is

46

acquiring the Acquired Membership Interests for its own account and not with a view toward or for offer or sale in connection with any distribution thereof in violation of federal or state securities Laws, or with any present intention of distributing or selling the Acquired Membership Interests in violation of federal or state securities Laws.

Section 4.9 Independent Investigation. Purchaser is (and its advisors are) experienced and knowledgeable in the oil and gas business and aware of the risks of that business. Purchaser acknowledges and affirms that (a) as of the Execution Date, it has made all such independent investigation, verification, analysis and evaluation of the Company Assets and the Company as it deems necessary or appropriate to enter into this Agreement and (b) it has made all such reviews and inspections of the Company Assets and the business, books and records, results of operations, conditions (financial or otherwise) and prospects of the Company as it has deemed necessary or appropriate to execute and deliver this Agreement. Except for the representations and warranties expressly made by Seller in Article 3 and Section 6.8 of this Agreement or in the certificates to be delivered to Purchaser pursuant to Section 8.2(d) of this Agreement, Purchaser acknowledges that there are no representations or warranties, express or implied, as to the financial condition, assets, Damages, equity, operations, business or prospects of the Company Assets or the Company or any Affiliate thereof, and that in making its decision to enter into this Agreement and to consummate the transactions contemplated hereby, Purchaser has relied solely upon the representations and warranties expressly made in Article 3 and Section 6.8 and its own independent investigation, verification, analysis and evaluation.

Other than restrictions on transfer due to the fact that the Purchaser Parent Shares are expected to be “restricted” securities under federal and state securities Laws by virtue of being issued in a transaction exempt from SEC registration, the Purchaser Parent Shares will not be subject to more onerous restrictions on tradability or transfer than the

47

common shares of Purchaser Parent already held by Seller and its Affiliates as of the Execution Date.

Section 4.13 SEC Reports. Purchaser Parent has filed and made available to Seller via EDGAR all forms, reports and other documents publicly filed by Purchaser Parent with the Securities and Exchange Commission under the Exchange Act, since January 1, 2019. All such forms, reports and other documents, including any audited or unaudited financial statements and any notes thereto or schedules included therein (including those that Purchaser Parent may file after the date hereof and prior to the Closing Date) are referred to herein as the “Purchaser Parent SEC Reports.” The Purchaser Parent SEC Reports (a) were filed on a timely basis, (b) comply in all material respects with the applicable requirements of the Exchange Act and the rules and regulations of the Securities and Exchange Commission thereunder and (c) did not, at the time they were filed (except to the extent corrected or superseded by a subsequent Purchaser Parent SEC Report), (i) in the case of any registration statement, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) in the case of Purchaser Parent SEC Reports other than registration statements, include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Notwithstanding the foregoing provisions of this Section 5.3, in the event of an emergency, Seller may take such action as reasonably necessary in response to such emergency and shall notify Purchaser of such action reasonably promptly thereafter.

54

which, if existing at the Execution Date or thereafter, would have been required to be set forth or described in such Schedules; provided that Seller shall use its commercially reasonable efforts to provide Purchaser with oral notice by telephone at least two (2) Business Days prior to any such addition, amendment, or supplement to the Schedules, and Seller shall cooperate with Purchaser as reasonably requested by Purchaser with respect to drafting any such addition, amendment, or supplement to the Schedules. Except as set forth in the last sentence of this Section 5.4, any disclosure in any such addition, amendment or supplement shall not be deemed to have subsequently cured any inaccuracy in or breach of any representation or warranty as of the date made in this Agreement, including for the purposes of indemnification and termination rights contained in this Agreement or determining whether the conditions set forth in Section 7.2(a) have been fulfilled.

If applicable, Seller and Purchaser shall (x) make or cause to be made any filings that may be required under the HSR Act and any other applicable Antitrust Law, with respect to the transactions contemplated hereby as promptly as practicable, but with respect to the HSR Act, in no event later than ten (10) Business Days, after the Execution Date, (y) bear their own costs and expenses incurred in connection with such filings and shall each pay fifty percent (50%) of any filing fees in connection therewith, and (z) use their commercially reasonable efforts to respond at the earliest practicable date to any requests for additional information made by the Antitrust Division of the Department of Justice (the “DOJ”), the Federal Trade Commission (the “FTC”) or any other applicable Governmental Authority. In connection with this Section 5.5, the Parties shall, to the extent permitted by Laws, (i) cooperate in all material respects with each other in connection with any filing, submission, investigation or inquiry, (ii) absent an objection from a Governmental Authority, provide advance notice and allow the other Party or Parties to participate in every communication with a Governmental Authority, provided that this clause shall not apply to a communication initiated by the Governmental Authority without advance notice to a Party, in which case the next clause shall apply, (iii) promptly inform the other Party or Parties of any communication received by such Party from, or given by such Party to, the DOJ or the FTC or any other Governmental Authority and of any material communication received or given in connection with any proceeding by a private party, in each case, regarding the transactions contemplated hereby, (iv) have the right to review in advance, and to the extent practicable, each shall consult any other on, any filing made with, or written materials to be submitted to, the DOJ, the FTC or any other Governmental Authority or, in connection with any proceeding by a private party, any other Person, in connection with the transactions contemplated hereby, and (v) consult with each other in advance of any meeting, discussion, telephone call or conference with the DOJ, the FTC or any other Governmental Authority or, in connection with any proceeding by

55

a private party, with any other Person. Each of Seller and Purchaser shall provide the other Party or Parties with information that is reasonably requested and that is reasonably necessary to obtain the expiration of the waiting period under the HSR Act; provided, however, that no Party would be required to share information that (A) is subject to the attorney-client or work product privilege, absent entry of a mutually acceptable joint defense agreement or (B) reflects the value of the transaction.

The Parties understand that none of the Sinking Funds set forth on Schedule A and maintained by Seller, Castex or any of their Affiliates on behalf of the Company are to be transferred to Purchaser, and none of the Sinking Funds (including those not set forth on Schedule A, if any) are intended to be for the economic benefit of Purchaser, or, following the Closing, the Company, but that certain of the bonds, letters of credit, cash collateral or guarantees posted by Company with a Governmental Authority or third Person shall stay with the Company post-Closing at the risk and expense of Purchaser. Purchaser shall use commercially reasonable efforts to assist Seller in its efforts to cause, effective as of the Closing or after Closing if applicable, the release of Seller from any bonds, letters of credit, cash collateral and guarantees posted (or supported) by Seller, the Company or any of its Affiliates, or any associated agreements with sureties; provided that, notwithstanding the foregoing, (a) Seller acknowledges and agrees that Purchaser does not warrant that Seller will be released from such bonds, letters of credit, cash collateral and guarantees by the applicable third party, which release shall be the sole responsibility of Seller or its Affiliates, and (b) subject to Purchaser’s use of commercially reasonable efforts as required by this sentence, Purchaser shall not (except as set forth in the

56

immediately succeeding sentence and associated indemnification set forth in Section 11.2(a)(i)) be liable to any Seller Indemnified Party if Seller is not released from any such bonds, letters of credit, cash collateral and guarantees or associated agreements with sureties by the applicable third party. For the avoidance of doubt, if the applicable third party calls upon or draws down any such unreleased bonds, letters of credit, cash collateral, guarantees or associated agreements with sureties, any Damages with respect thereto incurred by any Seller Indemnified Party shall be covered by the indemnification set forth in Section 11.2(a)(i) as applicable.

If Purchaser or Seller discovers any Preferential Purchase Right following the Execution Date that is not set forth in Schedule 3.11(a), Seller, within five (5) Business Days of the date Seller becomes aware of such Preferential Purchase Right, shall send to the holder of each such Preferential Purchase Right a notice in material compliance with the contractual provisions applicable to such Preferential Purchase Right. Seller shall provide Purchaser with (x) a copy of each notice and all other materials delivered to any such holder pursuant to this Section 5.11(a) promptly after sending the same to such holder and (y) copies of any written responses received from any such holder promptly after receiving the same.

(i) If, prior to Closing, any holder of a Preferential Purchase Right notifies Seller that it intends to consummate the purchase of the Company Asset to which its Preferential Purchase Right applies, then such Company Asset shall be excluded from the Company Assets to be assigned to Purchaser at Closing (but only to the extent of the portion of such Company Asset affected by the Preferential Purchase Right), and the Cash Purchase Price shall be reduced by the Allocated Value of the Company Lease, Company Unit or Company Well (or portion thereof) so excluded. Seller shall be entitled to all proceeds paid by any Person exercising a Preferential Purchase Right prior to Closing. If such holder of such Preferential Purchase Right thereafter fails to consummate the purchase of the Company Asset (or portion thereof) covered by such Preferential Purchase Right on or before the end of the period of time for closing such sale but not later than sixty (60) days following the Closing Date, (A) Seller shall so notify Purchaser, (B) Purchaser shall purchase, on or before ten (10) days following receipt of such

57

notice, the Company Asset (or portion thereof) that was so excluded from the Company Assets to be assigned to Purchaser at Closing prior to Closing, under the terms of this Agreement and for a price equal to the amount by which the Cash Purchase Price was reduced at Closing with respect to such excluded Company Asset (or portion thereof), and (C) Seller shall assign to Purchaser such Company Asset (or portion thereof) so excluded at Closing pursuant to a mutually agreeable assignment and bill of sale.

(ii) If, as of Closing, the time for exercising a Preferential Purchase Right has not expired and such Preferential Purchase Right has not been exercised or waived, then the Company Asset subject to such Preferential Purchase Right shall not be included in the Company Assets to be assigned to Purchaser at Closing, and the Cash Purchase Price shall be reduced by the Allocated Value of the Company Lease, Company Unit or Company Well (or portion thereof) being excluded. In the event that such holder exercises its Preferential Purchase Right following the Closing and consummates the purchase of the Company Asset (or portion thereof) covered by such Preferential Purchase Right in accordance therewith, Seller shall have no further obligation to sell or convey the affected Company Asset (or portion thereof) and Purchaser shall have no further obligation to purchase, accept or pay for such affected Company Asset (or portion thereof), and the affected Company Asset (or portion thereof) shall be excluded from the Company Assets to be assigned to Purchaser at Closing hereunder. If, within sixty (60) days following the Closing Date, (x) the applicable Preferential Purchase Right is waived or expires without exercise by the holder thereof or (y) the holder that has exercised the applicable Preferential Purchase Right after Closing thereafter fails to consummate the purchase of the Company Asset (or portion thereof) covered by such Preferential Purchase Right on or before the end of the period of time for closing such sale, (A) Seller shall so notify Purchaser, (B) Purchaser shall purchase, on or before ten (10) days following receipt of such notice, such Company Asset (or portion thereof) that was so excluded from the Company Assets, under the terms of this Agreement and for a price equal to the amount by which the Cash Purchase Price was reduced at Closing with respect to such excluded Company Asset (or portion thereof) and (C) Seller shall assign to Purchaser such Company Asset (or portion thereof) so excluded at Closing pursuant to a mutually agreeable assignment and bill of sale.

(iii) All Company Assets for which any applicable Preferential Purchase Right has been waived, or as to which the period to exercise the applicable Preferential Purchase Right has expired without exercise by the holder thereof, in each case, prior to Closing, shall be sold to Purchaser at Closing pursuant to the provisions of this Agreement.

(b) With respect to each Consent set forth in Schedule 3.11(b), within ten (10) Business Days of the date hereof, Seller shall send to the holder of each such Consent a notice in material compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated hereby. If Purchaser or Seller discovers any Consent following the Execution Date that is not set forth in Schedule

58

3.11(b), Seller, within five (5) Business Days of the date Seller becomes aware of such Consent, shall send to the holder of each such Consent a notice in material compliance with the contractual provisions applicable to such Consent. Seller shall provide Purchaser with (i) a copy of each notice and all other materials delivered to any such holder pursuant to this Section 5.11(b) promptly after sending the same to such holder and (ii) copies of any written responses received from any such holder promptly after receiving the same.

(i) If (A) Seller fails to obtain a Consent prior to Closing and the failure to obtain such Consent would cause (1) the change of control of the Company Asset affected thereby to Purchaser to be void or voidable or (2) the termination of a Company Lease, Company Right-of-Way or Company Contract under the express terms thereof (or give the holder of such Company Lease, Company Right-of-Way or Company Contract the express right to terminate the same) or (B) a Consent requested by Seller is denied in writing (each, a “Hard Consent”), then, in each case, the Company Asset (or portion thereof) affected by such un-obtained Consent shall be excluded from the Company Assets, and the Cash Purchase Price shall be reduced by the Allocated Value of the Company Lease, Company Unit or Company Well (or portion thereof) so excluded. In the event that a Consent with respect to a Company Asset excluded pursuant to this Section 5.11(b) that was not obtained prior to Closing is obtained within sixty (60) days following Closing, then, within ten (10) days after such Consent is obtained, (x) Purchaser shall purchase the Company Asset (or portion thereof) that was so excluded as a result of such previously un-obtained Consent and pay to Seller the amount by which the Cash Purchase Price was reduced at Closing with respect to the Company Asset (or portion thereof) so excluded and (y) Seller shall assign to Purchaser such Company Asset (or portion thereof) so excluded at Closing pursuant to a mutually agreeable assignment and bill of sale.

(ii) If Seller fails to obtain a Consent prior to Closing and such Consent is not a Hard Consent, then the Company Asset (or portion thereof) subject to such un-obtained Consent shall nevertheless be included in the Company Assets at Closing, without adjustment to the Cash Purchase Price.

(iii) Prior to Closing, Seller and Purchaser shall use their commercially reasonable efforts to, and Seller shall cause the Company to use its commercially reasonable efforts to, obtain all Consents; provided, however, that no Party shall be required to incur any Damages to the holder of such Consent or pay any money in order to obtain any such Consent.

63

commercially reasonable efforts to request and obtain any consents or waivers necessary for Purchaser and Purchaser’s Representatives to gain such access, provided, further, that Seller shall not be obligated to expend any monies or incur any Damages). Seller shall provide Purchaser and/or Purchaser’s Representatives with reasonable access to the representatives of Castex for the purposes of Purchaser’s due diligence investigation of the Company Assets.

Purchaser shall, and shall cause Purchaser’s Representatives to, abide by the applicable operators’ implemented safety rules, regulations and operating policies of which they are informed in conducting Purchaser’s Environmental Review. The scope of work comprising Purchaser’s Environmental Review shall be limited to those activities permitted by the applicable operator and any contractual obligations burdening Seller or the Company, and shall not include any sampling, testing or other invasive activities.

To assert a claim with respect to a Title Defect, or a Title Benefit, as applicable, and for such claim to be effective, Seller or Purchaser must deliver a Title Notice which substantially satisfies the requirements set forth in the definition of Title Notice on or before the Title Defect Deadline. Except for claims with respect to a breach of the representations and warranties set forth in Section 3.11, Section 3.16(b), Section 3.19, Section 3.20, Section 3.21, Section 3.23, Section 3.24, Section 3.33(e) or Section 6.8, from and after Closing, Seller and Purchaser shall be deemed to have waived, and neither Purchaser nor Seller, respectively, shall have any Damages for, any Title Benefit or Title Defect for which Purchaser or Seller, respectively, has not received a Title Notice that substantially satisfies the requirements set forth in the definition of Title Notice on or before the Title Defect Deadline; provided, however, that the foregoing shall not release Purchaser from any breach of its obligation to deliver a Title Notice in connection with its discovery of a Title Defect or Title Benefit prior to the Title Defect Deadline.

(b) With respect to each Company Lease, Company Unit or Company Well for which Purchaser has asserted a Title Defect pursuant to a timely delivered Title Notice in substantial compliance with the definition of Title Notice (each such Company Lease, Company Unit or Company Well, a “Title Defect Property”), Seller shall have the right until the Closing Date to cure any asserted Title Defect and/or to notify Purchaser of those asserted Title Defects that Seller disputes (each, a “Title Dispute Election”). Subject to Seller’s continuing right to dispute the existence of a Title Defect or the Title Defect Amount with respect thereto, with respect to each uncured Title Defect Property timely reported under Section 6.4(a), Seller shall have the right to elect any of the following:

66

(i) if Purchaser and Seller mutually agree, Seller shall cause to be conveyed by the Company to Seller or its designee immediately prior to the Closing such Title Defect Property (and, in each case, all related or associated Company Assets), in which case, (A) such Title Defect Property (and related or associated Company Assets), as applicable, shall be excluded from the Closing, (B) if excluded, such Title Defect Property (and related or associated Company Assets) shall become “Excluded Assets” for all purposes hereunder, and (C) the Cash Purchase Price shall be reduced by the Allocated Value of such Title Defect Property; or

(ii) such Title Defect Property (and all related or associated Company Assets) (any such Title Defect Property, together with all other such Title Defect Properties, the “Included Title Defect Properties”) shall be included at Closing with the Company Assets, subject to all such uncured Title Defects, in which case, subject to Section 6.4(c), the Cash Purchase Price shall be reduced at Closing by the Title Defect Amount.

(c) With respect to any Included Title Defect Property for which there is a timely delivered Title Dispute Election, the Closing Cash Payment shall be reduced by the Disputed Amount, which shall be paid into the Defect and Indemnity Escrow Account at Closing, the provisions of Section 6.7 shall apply and at the resolution of such Disputed Matter pursuant to Section 6.7, the Disputed Amount shall be delivered to Seller or Purchaser pursuant to the decision of the Defect Arbitrator pursuant to Section 6.7.

Section 6.5 Title Defect Amount; Title Benefit Amount; Adjustments.

(a) The amount by which the Allocated Value of any Company Lease, Company Unit or Company Well (or Company Leases, Company Units or Company Wells if multiple Company Leases, Company Units or Company Wells are affected) is reduced as a result of the existence of a Title Defect with respect thereto is the “Title Defect Amount”, which shall be determined in accordance with the following methodology, terms and conditions:

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

(ii) if the Title Defect represents a decrease in (A) the actual Net Revenue Interest for any Company Lease, Company Unit or Company Well below (B) the Net Revenue Interest stated on the Lease Annex for such Company Lease or Company Unit or on the Well Annex for such Company Well (and there is a proportionate decrease in the Working Interest for such Company Lease, Company Unit or Company Well below the Working Interest stated on the Lease Annex or on the Well Annex), then the Title Defect Amount shall be the product of (y) the Allocated Value for such Company Lease, Company Unit or Company Well multiplied by (z) one (1), minus a fraction, the numerator of which is the actual Net Revenue Interest for such Company Lease, Company Unit or Company Well and the denominator of which is the Net Revenue Interest for such Company Lease or

67

Company Unit stated on the Lease Annex or for such Company Well as stated on the Well Annex;

(iii) if the Title Defect is based on a Lien upon a Company Lease, Company Unit or Company Well that is undisputed and liquidated in amount, then the amount of such Title Defect shall be lesser of the amount necessary to remove such Lien from the affected Company Lease, Company Unit or Company Well and the Allocated Value of the affected Company Lease, Company Unit or Company Well;

(iv) if the Title Defect is based on an obligation, encumbrance, Burden or charge upon or other defect in title to the affected Company Lease, Company Unit or Company Well of a type not described in Sections 6.5(a)(i), (ii) or (iii), then, subject to the other provisions hereof, the Title Defect Amount shall be determined by the Parties in good faith, taking into account all relevant factors, including the following: (A) the Allocated Value of that Company Lease, Company Unit or Company Well; (B) the portion of the affected Company Lease, Company Unit or Company Well affected by such Title Defect; (C) the legal effect of the Title Defect; (D) the potential economic effect of the Title Defect over the life of the affected Company Lease, Company Unit or Company Well; (E) the values placed upon the Title Defect by Purchaser and Seller; and (F) such other reasonable factors as are necessary to make a proper evaluation;

(v) the Title Defect Amount with respect to any Company Lease, Company Unit or Company Well shall be determined without duplication of any costs or losses (A) included in another Title Defect Amount hereunder, (B) included in any remedy for a Casualty Loss under Section 5.13, or (C) for which Purchaser otherwise receives credit in the calculation of the adjustments to the Cash Purchase Price; and

(vi) notwithstanding anything to the contrary set forth herein, except for the Title Defect Amounts described in clause (iv) of this Section 6.5(a), the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Company Lease, Company Unit or Company Well shall not exceed the Allocated Value of such Company Lease, Company Unit or Company Well.

(b) The only remedy for Title Benefits is the netting against Title Defect Amounts which is only available for Title Benefit Amounts exceeding the Title Threshold. Each “Title Benefit Amount” shall be determined in accordance with the following methodology, terms and conditions:

(i) if Purchaser and Seller agree on the Title Benefit Amount, then such amount shall be the Title Benefit Amount;

(ii) if the Title Benefit represents an increase in (A) the actual Net Revenue Interest for any Company Lease, Company Unit or Company Well over (B) the Net Revenue Interest stated on the Lease Annex for such Company Lease

68

or Company Unit or on the Well Annex for such Company Well (and there is a proportionate increase in the Working Interest for such Company Lease, Company Unit or Company Well above the Working Interest stated on the Lease Annex or on the Well Annex), then the Title Benefit Amount shall be the product of (y) the Allocated Value of such Company Lease, Company Unit or Company Well, multiplied by (z) the result obtained by subtracting one (1) from a fraction, the numerator of which is the actual Net Revenue Interest for such Company Lease, Company Unit or Company Well and the denominator of which is the Net Revenue Interest for such Company Lease or Company Unit stated on the Lease Annex or for such Company Well stated on the Well Annex; and

(iii) if the Title Benefit is not of a type described in Sections 6.5(b)(i) or (ii), then, subject to the other provisions hereof, the Title Benefit Amount shall be determined by the Parties in good faith, taking into account all relevant factors, including the following: (A) the Allocated Value of the affected Company Lease, Company Unit or Company Well; (B) the portion of the affected Company Lease, Company Unit or Company Well affected by such Title Benefit; (C) the legal effect of the Title Benefit; (D) the potential economic effect of the Title Benefit over the life of the affected Company Lease, Company Unit or Company Well; (E) the values placed upon the Title Benefit by Purchaser and Seller; and (F) such other reasonable factors as are necessary to make a proper evaluation.

(c) Notwithstanding anything herein to the contrary, in no event shall there be any remedies provided by Seller or any adjustments to the Purchase Price for (i) any individual Title Defect for which the Title Defect Amount does not exceed Fifty Thousand Dollars ($50,000) (the “Title Threshold”) or (ii) any individual Environmental Defect for which the Environmental Defect Amount does not exceed Fifty Thousand Dollars ($50,000) (the “Environmental Threshold”). Notwithstanding anything herein to the contrary, in addition, there shall be no remedies provided by Seller or any adjustments to the Purchase Price unless and until (A) the aggregate amount of all Title Defect Amounts of all Title Defects that exceed the Title Threshold and which remain uncured by the Closing Date, less (B) the aggregate amount of all Title Benefit Amounts that exceed the Title Threshold, exceeds an amount equal to one percent (1%) of the Unadjusted Purchase Price (the “Title Deductible”), and then, such remedies and/or adjustment shall apply only to the extent that the aggregate of such Title Defect Amounts (less such Title Benefit Amounts) exceeds the Title Deductible.

Section 6.6 Notice of Environmental Defects; Remedies.

(a) If Purchaser discovers any Environmental Defect, then Purchaser may (but shall have no obligation to) deliver to Seller prior to 5:00 p.m., Central Time, on the thirtieth (30th) day after the Execution Date (the “Environmental Defect Deadline”), an Environmental Notice with respect to such Environmental Defect. To assert a claim with respect to an Environmental Defect, and for such claim to be effective, Purchaser must deliver an Environmental Notice which substantially satisfies the requirements set forth in the definition of Environmental Notice on or before the Environmental Defect Deadline. Notwithstanding any other provision in this Agreement, Purchaser shall be deemed to have

69

waived, and Seller shall have no Damages for, any Environmental Defect for which Seller has not received an Environmental Notice that substantially satisfies the requirements set forth in the definition of Environmental Notice on or before the Environmental Defect Deadline.

(b) With respect to each Company Asset for which Purchaser has asserted an Environmental Defect pursuant to a timely delivered Environmental Notice in substantial compliance with the definition of Environmental Notice (each such Company Asset, an “Environmental Defect Property”), Seller may elect (in its sole and absolute discretion, and in addition to Seller’s rights under Section 6.6(c)) to complete the cure of such Environmental Defect Property prior to Closing in accordance with Section 6.6(c), in which event any adjustment to the Cash Purchase Price with respect to such Environmental Defect Property shall be made, if applicable, at the time of Closing in accordance with Section 6.6(c).

(c) With respect to any Environmental Defect Property, until the time of Closing, Seller may, but shall have no obligation to, (i) dispute the existence of the Environmental Defect and/or the Environmental Defect Amount asserted with respect to such Environmental Defect Property pursuant to the provisions of Section 6.7 (each, an “Environmental Dispute Election”) or (ii) cure any Environmental Defect asserted with respect to such Environmental Defect Property prior to Closing. With respect to any Environmental Defect Property for which there is a timely delivered Environmental Dispute Election, the provisions of Section 6.7 shall apply and at the resolution of such Disputed Matter pursuant to Section 6.7, the Disputed Amount shall be delivered to Seller or Purchaser pursuant to the decision of the Defect Arbitrator pursuant to Section 6.7. Subject to Seller’s continuing right to dispute the existence of an Environmental Defect or the Environmental Defect Amount with respect thereto, with respect to each Environmental Defect Property timely reported under Section 6.6(a), if, at the time of Closing, Seller has cured (or partially cured) any Environmental Defect affecting any Environmental Defect Property, then the Cash Purchase Price shall not be adjusted (and if such Environmental Defect was only partially cured, the Cash Purchase Price shall be decreased by an amount equal to the portion of such Environmental Defect Amount that relates to the uncured portion of such Environmental Defect), or, if such Environmental Defect was not cured, the Cash Purchase Price shall be decreased by an amount equal to such Environmental Defect Amount that relates to such Environmental Defect. Notwithstanding anything set forth in this Section 6.6(c), if at the time of Closing, any Environmental Defect Property has an Environmental Defect, the Environmental Defect Amount of which is sixty percent (60%) or more of the Allocated Value of such Environmental Defect Property, then, at Purchaser’s election and upon written notice given to Seller prior to the Closing, Seller shall cause to be conveyed by the Company to Seller or its designee immediately prior to the Closing, as applicable, such Environmental Defect Property (and, in each case, all related or associated Company Assets), in which case, (A) such Environmental Defect Property (and related or associated Company Assets), as applicable shall be excluded from the Closing, (B) if excluded, such Environmental Defect Property (and related or associated Company Assets) shall become “Excluded Assets” for all purposes hereunder, and (C) the Cash Purchase Price shall be reduced by the Allocated Value of such Environmental Defect Property.

70

(d) Notwithstanding anything herein to the contrary, in addition, there shall be no remedies provided by Seller or any adjustments to the Purchase Price unless and until the aggregate of all Environmental Defect Amounts for Environmental Defects that remain uncured by Closing and that exceed the Environmental Threshold, exceeds an amount equal to one percent (1%) of the Unadjusted Purchase Price (the “Environmental Deductible”), and then only to the extent that the aggregate of such Environmental Defect Amounts exceeds the Environmental Deductible.

Section 6.7 Title and Environmental Dispute Resolution. Seller and Purchaser shall attempt to agree on the existence of any Title Defects, Title Benefits and Environmental Defects, any Title Defect curative or Environmental Defect Remediation matters, and all Title Defect Amounts, Title Benefit Amounts and Environmental Defect Amounts by three (3) Business Days prior to the Closing Date. If, as of the Closing, the Parties cannot agree upon (a) the existence of a Title Defect or Title Benefit, the adequacy of any Title Defect curative materials submitted to Purchaser, the Title Defect Amount with respect to any Title Defect or the Title Benefit Amount with respect to any Title Benefit (each, a “Disputed Title Matter”) or (b) the existence of an Environmental Defect, the adequacy of any Environmental Defect Remediation performed by Seller, or the Environmental Defect Amount with respect to any Environmental Defect (each, a “Disputed Environmental Matter” and, together with any Disputed Title Matter, each a “Disputed Matter”), then, in each case, the Disputed Matter shall be submitted to arbitration in accordance with the provisions of Exhibit D attached hereto. At Closing, the Title Defect Amount, the Title Benefit Amount or the Environmental Defect Amount that is subject to the Disputed Matter (each a “Disputed Amount”) shall be paid by Purchaser into the Defect and Indemnity Escrow Account at Closing pending resolution of the Disputed Matter and the Closing Cash Payment shall be reduced by such Disputed Amount, and such Disputed Amount shall be released to Seller or Purchaser, as applicable, upon resolution of such Disputed Matter. Upon resolution of a Disputed Matter, the Parties shall instruct the Escrow Agent to release the applicable Disputed Amount to Seller or Purchaser, as applicable, within five (5) days after the resolution of such Disputed Matter.

Section 6.8 Special Warranty of Defensible Title. Notwithstanding anything herein to the contrary, if Closing occurs, then, Seller hereby warrants unto Purchaser Defensible Title as to each Company Lease, Company Unit and Company Well contained in the Company Assets against any Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under the Company, any of its Affiliates or Castex, but not otherwise, subject, however, to the Permitted Encumbrances. For purposes of Seller’s foregoing special warranty of Defensible Title, the value of the Company Leases and Company Units set forth in the Lease Annex and of the Company Wells set forth in the Well Annex shall be deemed to be the Allocated Value thereof. For the avoidance of doubt and notwithstanding anything in this Agreement to the contrary, the Title Threshold and the Title Deductible shall in no way limit any claim by Purchaser pursuant to this Section 6.8.

71

To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes as having been paid to the Person to whom such amounts would otherwise have been paid absent such deduction or withholding.

Section 9.2 Tax Returns.

(a) Seller shall prepare or cause to be prepared all Tax Returns of the Company (i) required to be filed after the date hereof for all Pre-Effective Date Periods and (ii) required to be filed after the date hereof but on or prior to the Closing Date for all Straddle Periods (the “Seller Tax Returns”). Such Seller Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Reasonably in advance of the due date for the filing of any such Seller Tax Return, Seller shall deliver a draft of such Tax Return, together with all supporting documentation and workpapers, to Purchaser for its review and reasonable comment. Purchaser or Seller, as applicable, will cause such Tax Return (as revised to incorporate Purchaser’s reasonable comments) to be timely filed and will provide a copy thereof to the non-filing Party. Not

77

later than five (5) days prior to the due date for payment of Taxes with respect to any Seller Tax Return filed by Purchaser, Seller shall pay to Purchaser the amount of any Seller Taxes with respect to such Tax Return.

(b) Purchaser shall prepare or cause to be prepared all Tax Returns of the Company required to be filed after the Closing Date for all Straddle Periods (“Purchaser Tax Returns”). Such Purchaser Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Reasonably in advance of the due date for the filing of any such Purchaser Tax Returns, Purchaser shall deliver a draft of such Tax Return, together with all supporting documentation and workpapers, to Seller for its review and reasonable comment. Purchaser will cause such Tax Return (as revised to incorporate Seller’s reasonable comments) to be timely filed and will provide a copy thereof to Seller. Not later than five (5) days prior to the due date for payment of Taxes with respect to any Purchaser Tax Return, Seller shall pay to Purchaser the amount of any Seller Taxes with respect to such Tax Return.

Section 9.3 Proration of Straddle Period Taxes.

(a) For purposes of determining the portion of any Taxes (other than Asset Taxes) that are payable with respect to any Straddle Period that constitute Seller Taxes, the portion of any such Taxes that is attributable to the portion of such Straddle Period ending on the Tax Effective Date shall be deemed equal to the amount that would be payable if the Tax period of the Company ended with (and included) the Tax Effective Date (provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the portion of the Straddle Period ending on and including the Tax Effective Date and the portion of the Straddle Period beginning after the Tax Effective Date in proportion to the number of days in each portion of the Straddle Period).

(b) For purposes of determining the portion of any Assets Taxes that are payable with respect to any Straddle Period that constitute Seller Taxes, (I) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (III), below) shall be allocated to the period or portion thereof in which the severance or production giving rise to such Asset Taxes occurred, (II) Asset Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (I) or (III)), shall be allocated to the period or portion thereof in which the transaction giving rise to such Asset Taxes occurred, and (III) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending on the Tax Effective Date and the portion of such Straddle Period beginning after the Tax Effective Date by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur on and before the Tax Effective Date, on the one hand, and the number of days in such Straddle Period that occur after the Tax Effective Date, on the other hand.

Section 9.4 Cooperation on Tax Returns and Tax Proceedings. Purchaser and Seller shall cooperate fully as and to the extent reasonably requested by another Party, in

78

connection with the filing of Tax Returns and any Proceeding (each a “Tax Proceeding”) with respect to Taxes imposed on or with respect to the Company, the Company Assets and Company Business. Such cooperation shall include the retention and (upon another Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Seller further agrees, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on Purchaser or the Company (including, but not limited to, with respect to the transactions contemplated hereby). Notwithstanding the above, the control and conduct of any Tax Proceeding that is a Claim shall be governed by Section 11.3.

Section 9.5 Transfer Taxes. Purchaser and Seller shall each be responsible for (and shall, without duplicating recovery available to Purchaser pursuant to clause (iv) of the definition of Seller Taxes, indemnify the other against) the payment of one-half of all state and local transfer, sales, use, stamp, registration or other similar Taxes resulting from the purchase and sale of the Company pursuant to Section 1.1 (“Transfer Taxes”). Seller shall be solely responsible for (and shall, without duplicating recovery available to Purchaser pursuant to clause (iv) of the definition of Seller Taxes, indemnify Purchaser against) the payment of all state and local transfer, sales, use, stamp, registration or other similar Taxes resulting from any other transactions contemplated by this Agreement, including any transactions relating to Excluded Assets. Purchaser and Seller shall cooperate in good faith to minimize, to the extent permissible under Law, the amount of any such Transfer Taxes.

Section 9.6 Tax Refunds. The amount of any refunds of Taxes of the Company for any Pre-Effective Date Period shall be for the account of Seller. The amount of any refunds of Taxes of the Company for any Tax period beginning after the Tax Effective Date shall be for the account of Purchaser. The amount of any refund of Taxes of the Company for any Straddle Period shall be equitably apportioned between Purchaser and Seller in accordance with the principles set forth in Section 9.3. Each Party shall forward, and shall cause its Affiliates to forward, to the Party entitled to receive a refund of Tax pursuant to this Section 9.6 the amount of such refund within 30 days after such refund is received, net of any costs or expenses incurred by such Party or its Affiliates in procuring such refund.

ARTICLE 10

TERMINATION

Section 10.1 Termination. This Agreement may be terminated at any time prior to Closing:

(a) by the prior written consent of Seller and Purchaser;

(b) by Seller or Purchaser, as applicable, by written notice to the other Party, if Purchaser or Seller, as applicable, is in material breach of any covenant or a representation in this Agreement, which breach would give rise to the failure of a condition set forth in Article 7 to be satisfied and is incapable of being cured, or if capable of being cured, is not

79

cured, by such breaching Party by the earlier of (i) thirty (30) days following receipt of written notice from the non-breaching Party of such breach or (ii) the Outside Date; or

(c) by Seller or Purchaser, as applicable, by written notice to the other Party, if Closing has not occurred on or before April 30, 2020 (the “Outside Date”);

provided, however, that no Party shall be entitled to terminate this Agreement under Section 10.1(b) or Section 10.1(c) (except with respect to a failure of the condition set forth in Section 7.1(d) or Section 7.2(d)) if the Closing has failed to occur because such Party is in material breach of any of its representations or warranties hereunder or has failed to perform or observe in any material respect its covenants or agreements hereunder.

Section 10.2 Effect of Termination.

(a) If this Agreement is terminated pursuant to Section 10.1, this Agreement shall become void and of no further force or effect (except for the provisions of Section 1.2 (to the extent necessary to give meaning to the following Articles and Sections), Section 3.12, Section 4.10, Section 5.1, Section 5.4, Section 5.16 (insofar only as Seller has a right to be reimbursed), Section 6.2(b), Article 10, Section 12.1, Section 12.2, Section 12.3, Section 12.6, Section 12.7, Section 12.8, Section 12.9, Section 12.11, Section 12.13, Section 12.14, Section 12.15, Section 12.16, Section 12.17 and Section 12.19 and of the Confidentiality Agreement, all of which shall continue in full force and effect). Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Section 10.1 shall not relieve any Party from Damages for any willful failure to perform or observe in any material respect any of its agreements or covenants contained herein that are to be performed or observed at or prior to Closing.

(b) If Seller has the right to terminate this Agreement pursuant to Section 10.1(b) because of the Willful Breach of Purchaser or the failure of Purchaser to Close by the Outside Date when (i) all of the conditions precedent to the obligations of Purchaser set forth in Section 7.2 (other than those actions or deliveries to occur at Closing or contingent upon the satisfaction of other conditions precedent set forth in Section 7.1 at Closing) have been met, or waived in writing by Purchaser, and (ii) Seller is ready, willing and able to perform its obligations under Section 8.2 (other than those requiring the cooperation of Purchaser, unless such cooperation was provided), then, in either such event, as the sole and exclusive remedy of Seller, Seller shall have the right to, at its option, (1) seek the specific performance of Purchaser hereunder, or (2) terminate this Agreement pursuant to Section 10.1(b) and receive the Deposit from the Escrow Agent, free and clear of any claims thereon by Purchaser as liquidated damages. For the avoidance of doubt, Seller shall be entitled to first seek to enforce the remedies in subpart (1) of the previous sentence before enforcing its remedies set forth in subpart (2) of the previous sentence. The provision for payment of liquidated damages in this Section 10.2(b) has been included because, in the event of a termination of this Agreement permitting Seller to receive the Deposit, the actual damages to be incurred by Seller can reasonably be expected to approximate the amount of liquidated damages called for herein and because the actual amount of such damages would be difficult if not impossible to measure accurately. In the event that this Agreement may be terminated pursuant to either Section 10.1(b) by Seller

80

or Section 10.1(c) by either Party as of the Outside Date, then Seller shall have the superseding right to terminate this Agreement pursuant to Section 10.1(b); provided that if Purchaser then also has the right to terminate this Agreement pursuant to Section 10.1(b), then notwithstanding the foregoing this Agreement shall be deemed terminated pursuant to Section 10.1(c).

(c) If Purchaser has the right to terminate this Agreement pursuant to Section 10.1(b) because of the Willful Breach of Seller or the failure of Seller to Close by the Outside Date when (i) all of the conditions precedent to the obligations of Seller set forth in Section 7.1 (other than those actions or deliveries to occur at Closing or contingent upon the satisfaction of other conditions precedent set forth in Section 7.2 at Closing) have been met, or waived in writing by Seller, and (ii) Purchaser is ready, willing and able to perform its obligations under Section 8.3 (other than those requiring the cooperation of Seller, unless such cooperation was provided), then, in either such event, as the sole and exclusive remedy of Purchaser, Purchaser shall have the right to, at its option, (1) seek the specific performance of Seller hereunder, or (2) terminate this Agreement pursuant to Section 10.1(b) and be entitled to (x) receive the Deposit from the Escrow Agent, free and clear of any claims thereon by Seller (provided that in such event, Seller agrees to execute any joint written instructions required under the terms of the Escrow Agreement such that Purchaser may receive its remedy under the foregoing subpart (2)(x)), and (y) seek to recover actual damages from Seller up to an amount equal to the amount of the Deposit. For the avoidance of doubt, Purchaser shall be entitled to first seek to enforce the remedies in subpart (1) of the previous sentence before enforcing its remedies set forth in subpart (2) of the previous sentence. In the event that this Agreement may be terminated pursuant to either Section 10.1(b) by Purchaser or Section 10.1(c) by either Party as of the Outside Date, then Purchaser shall have the superseding right to terminate this Agreement pursuant to Section 10.1(b); provided that if Seller then also has the right to terminate this Agreement pursuant to Section 10.1(b), then notwithstanding the foregoing this Agreement shall be deemed terminated pursuant to Section 10.1(c).

(d) If this Agreement is terminated by the mutual written agreement of the Parties, or this Agreement is otherwise terminated pursuant to Section 10.1 and the Closing does not occur for any reason other than as set forth in Section 10.2(b) or Section 10.2(c), then Purchaser shall be entitled to the return of the Deposit, free of any claims by Seller with respect thereto.

(e) If either Seller or Purchaser are entitled to a distribution of the Deposit pursuant to this Section 10.2, each Party shall, within two (2) Business Days of the date of such termination, deliver to the Escrow Agent an executed counterpart of a joint written instruction in compliance with the terms of the Escrow Agreement directing the Escrow Agent to disburse the Deposit (together with any interest or income actually earned thereon) to the applicable Party as set forth in this Section 10.2. Upon termination, Seller shall have the right to sell the Acquired Membership Interests without any encumbrance or claim by Purchaser.

83

Notwithstanding the foregoing, Purchaser shall not be entitled to indemnification under the Interim Breach Provision for any Damages that does not individually exceed Fifty Thousand Dollars ($50,000).

(e) Any claim for indemnity under this Section 11.2 by any current or former Affiliate, member, manager, director, officer, employee, agent, advisor or representative must be brought and administered by the applicable Party to this Agreement that such Person is associated therewith. No Indemnified Person other than Seller and Purchaser shall have any rights against Seller or Purchaser under the terms of this Section 11.2 except as may be exercised on its behalf by Purchaser or Seller, as applicable, pursuant to this Section 11.2(e). Each of Seller and Purchaser may elect to exercise or not exercise indemnification rights under this Section 11.2(e) on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no Damages to any such other Indemnified Person for any action or inaction under this Section 11.2(e).

(f) After becoming aware of any fact, event, circumstance or condition that has given rise to or would reasonably be expected to give rise to any Damages, the Indemnified Persons shall use commercially reasonable efforts to mitigate Damages, for which efforts such Indemnified Persons are entitled or may be entitled to indemnification under this Section 11.2; provided that, to the extent the Indemnified Person incurs any costs or expenses in connection with such mitigation efforts, the Indemnifying Person shall reimburse the Indemnified Person with respect thereto upon the Indemnified Person providing the Indemnifying Person reasonable evidence of such costs and expenses.

(g) The Parties shall treat, for U.S. federal income Tax purposes, any amounts paid under this Article 11 as an adjustment to the Purchase Price.

84

Section 11.3 Indemnification Actions. All claims for indemnification under Section 11.2 shall be asserted and resolved as follows:

(a) For purposes of this Article 11, the term “Indemnifying Person” when used in connection with particular Damages means the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 11, and the term “Indemnified Person” when used in connection with particular Damages means a Person having the right to be indemnified with respect to such Damages pursuant to this Article 11 (including those Persons identified in Section 11.2(e)).

(b) To make a claim for indemnification under Section 11.2, an Indemnified Person shall notify the Indemnifying Person of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). The amount claimed shall be paid by the Indemnifying Person to the extent required herein within thirty (30) days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs. In the event that the claim for indemnification is based upon a claim by a third Person against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice within thirty (30) days after the Indemnified Person has received a written claim from such third Person and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 11.3 shall not relieve the Indemnifying Person of its obligations under Section 11.2 except to the extent (and only to the extent) such failure materially prejudices the Indemnifying Person’s ability to defend against the Claim. In the event that the 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.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Claim under this Article 11. The Indemnified Person may, during such thirty (30) day period and upon three (3) days’ prior written notice to the Indemnifying Person, file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person admits its obligation, it shall have the right and obligation to defend, at its sole cost and expense, the Claim, and the Indemnifying Person shall conduct such defense diligently with counsels reasonably satisfactory to the Indemnified Person; provided that no Indemnifying Person shall have the obligation to defend any Claim for which coverage is being sought under the R&W Policy. The Indemnified Person may retain separate co-counsel at its sole cost and expense and participate in the defense of the Claim. Notwithstanding the foregoing, if counsel for the Indemnified Person reasonably determines that there is a conflict between the positions of the Indemnifying Person and the Indemnified Person in conducting the defense of such Claim or that there are legal defenses available to such Indemnified Person different from

85

or in addition to those available to the Indemnifying Person, then one counsel for the Indemnified Person shall be entitled, if the Indemnified Person so elects, to participate in or conduct the defense to the extent reasonably determined by such counsel to protect the interests of the Indemnified Person, at the expense of the Indemnifying Person; provided that in no event shall the Indemnifying Person be required to pay the fees and expenses of more than one counsel selected by the Indemnified Person. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 11.3(d). No settlement of a Claim may be made by the Indemnifying Person without the written consent of the Indemnified Person, such consent not to be unreasonably withheld; provided, that such consent shall not be required for any settlement of a Claim that (i) is for monetary damages only and all of which have been fully discharged by the Indemnifying Person, (ii) does not include any ongoing obligations with respect to the Indemnified Person and (iii) absolves the Indemnified Person of all Damages with respect to such Claim.

(e) If the Indemnifying Person does not admit its obligation or admits its obligation but fails to defend or settle the Claim, then the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing. If the Indemnifying Person has not yet admitted its obligation to indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Claim and assume the defense thereof or (ii) if the Indemnifying Person fails to assume such defense within the time period provided above, the Indemnified Person may settle the same in the Indemnified Person’s reasonable discretion at the Indemnifying Person’s expense.

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to (i) completely cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages or (iii) dispute the claim for such Damages. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period that it has completely cured the Damages or that it disputes the claim for such Damages, the Indemnifying Person shall be conclusively deemed obligated to provide indemnification hereunder.

Section 11.4 Limitation on Actions.

Seller’s special warranty of Defensible Title in Section 6.8 shall survive the Closing for six (6) years.

(c) Representations, warranties, covenants and agreements shall be of no further force and effect after the date of the expiration of a right to assert an indemnification claim with respect thereto, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to the applicable expiration date.

(d) The indemnities in Section 11.2(a)(ii), Section 11.2(a)(iii), Section 11.2(b)(i) and Section 11.2(b)(ii) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date. The indemnities in Section 11.2(a)(i) shall continue without time limit. The indemnity in Section 11.2(b)(iii) shall survive the Closing until ninety (90) days after the applicable statute of limitations has run, except as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date.

(e) Seller shall not have any liability for any indemnification under the Interim Breach Provision, until and unless the aggregate amount of the liability for all Damages for which Claim Notices are delivered by Purchaser for indemnification under such Section exceed an amount equal to four percent (4%) of the Unadjusted Purchase Price, and then

87

only to the extent such Damages exceed such amount. Seller shall not have any liability for any indemnification under the Interim Breach Provision unless Purchaser provides Seller with written notice of an Interim Breach prior to the Closing Date in accordance with the notice provisions of this Agreement; provided that this requirement of Purchaser to provide written notice of any Interim Breach prior to the Closing Date shall not apply to Interim Breaches and/or the circumstance giving rise thereto notified by Seller to Purchaser pursuant to this Agreement.

(f) Notwithstanding anything to the contrary contained elsewhere in this Agreement, (i) Seller shall not be required to indemnify Purchaser for claims under the Interim Breach Provision for aggregate Damages in excess of an amount equal to ten percent (10%) of the Unadjusted Purchase Price, (ii) Seller shall not be required to indemnify Purchaser under Section 11.2(b)(ii)(B) for aggregate Damages in excess of an amount equal to $28,000.00, (iii) Seller shall not be required to indemnify Purchaser under Section 11.2(b)(i)(B) or Section 11.2(b)(ii)(A) for aggregate Damages in excess of an amount equal to $87,500.00, and (iv) Seller’s total Damages and liabilities arising out of this Agreement or the transactions contemplated hereunder, including with respect to indemnity obligations under Section 11.2(b) shall not exceed one hundred percent (100%) of the Unadjusted Purchase Price. For the avoidance of doubt, and notwithstanding anything to the contrary herein, the Parties intend that Seller’s sole and exclusive exposure from and after Closing with respect to the representations and warranties in Article 3 or in the closing certificate delivered pursuant to Section 8.2(d) shall be limited to the amounts set forth in Section 11.4(f)(i), Section 11.4(f)(ii), Section 11.4(f)(iii) and Section 11.4(f)(iv), as applicable.

(g) Notwithstanding anything herein to the contrary, for both the purposes of determining whether or not the representation or warranty of any Party in Article 3 or Article 4 or any closing certificate delivered pursuant to Section 8.2(d) or Section 8.3(b) has been breached, and the purposes of determining the amount of any Damages for which any Indemnifying Person is obligated to indemnify under Section 11.2(a)(iii) or Section 11.2(b)(ii), such determination of breach and calculation of Damages shall be made by excluding and without giving effect to any qualifiers as to materiality or Material Adverse Effect set forth in any representation or warranty of any Party in Article 3 or Article 4 or any closing certificate delivered pursuant to Section 8.2(d) or Section 8.3(b) (except in the case of the representations and warranties set forth in Section 3.14(a) and the representations and warranties made in respect of the Tax Partnerships as a result of Section 3.7(p) and the corresponding representations and warranties in any closing certificate delivered pursuant to Section 8.2(d)).

(h) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 11 shall be reduced by the amount of insurance proceeds actually realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any reasonable and documented collection costs, including all the costs and expenses incurred by third parties in investigating, prosecuting, defending and collecting such recovered amount and, any deductibles paid to obtain insurance coverage, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates). From and after the Closing, Seller shall (without any obligation

88

to incur out of pocket costs, expenses, or any obligation of Seller to undertake any liability or obligation to any Person) use good faith efforts to reasonably cooperate with Purchaser in connection with any claim made by Purchaser under the R&W Policy. Notwithstanding the foregoing, or any other provision herein, except solely with respect to the Interim Breach Provision, the risk that the R&W Policy will not respond or otherwise provide coverage (excluding, for the avoidance of doubt, retention under the R&W Policy) with respect to a given claim shall be borne entirely by Purchaser.

(i) Notwithstanding anything to the contrary contained herein, all payments made or to be made under this Article 11 to Purchaser shall be made by Seller by payment in cash and not via the return of any Purchaser Parent Shares.

(j) The representations, warranties and covenants of each of the Parties set forth in this Agreement, subject to the express exceptions thereto, shall not be affected by any information furnished to, or any investigation or audit conducted before or after the Closing Date by, any Person in connection with the transactions contemplated hereby. In order to preserve the benefit of the bargain otherwise represented by this Agreement, each Party shall be entitled to rely upon the representations, warranties, covenants and agreements of the other Party or Parties set forth herein notwithstanding any investigation or audit conducted or any knowledge acquired (or capable of being acquired) before or after the Closing Date or the decision of any Party to complete the Closing. The right to indemnification or other remedy based on any of the representations, warranties, covenants or agreements in this Agreement shall not be affected by any investigation or audit conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant, or agreement.

(k) Notwithstanding anything in this Agreement to the contrary, in no event shall any Indemnified Person be entitled to recover any Damages to which such Indemnified Person has already recovered the full amount of such Damages pursuant to another provision of this Agreement or any document in connection herewith, or otherwise, and any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant, or agreement.

Section 11.5 Escrow Claims.

(a) If any amounts are due by Seller to Purchaser pursuant to this Article 11 (other than this Section 11.5), then such amounts shall be first satisfied from the Indemnity Escrow Amount. To the extent that Purchaser is determined to be owed by Seller amounts in excess of the Indemnity Escrow Amount, Purchaser may seek payment for such amounts from Seller.

(b) If Seller does not dispute any claim made by Purchaser against Seller pursuant to this Article 11 (other than this Section 11.5), at Purchaser’s written election, Seller and Purchaser shall provide written instructions to the Escrow Agent in accordance

89

with the Escrow Agreement to disburse to Purchaser the amount of the undisputed claim. If Seller disputes any claim made by Purchaser pursuant to this Article 11 (other than this Section 11.5), then upon final determination of the applicable disputed amount or Damages (or a settlement between the Parties), as applicable, with respect to such claim, at Purchaser’s written election, Seller and Purchaser shall provide written instructions to the Escrow Agent to disburse to Purchaser the amount determined by such final determination or settlement to be due.

(c) On the date that is twenty-four (24) months after the Closing Date, Purchaser and Seller shall instruct the Escrow Agent to release to Seller (or its designee) the then existing amount of the Indemnity Escrow Amount, save and except (i) the aggregate amount of all unsatisfied claims for indemnification that Purchaser has made against Seller on or before such date pursuant to this Article 11 (other than this Section 11.5) and which are subject to satisfaction (in whole or in part) from the Indemnity Escrow Amount plus (ii) the aggregate amount of all disputed amounts or Damages that have not been resolved as of such date. After all disputed claims have been finally determined, and any amounts required to be paid to Purchaser from the Indemnity Escrow Amount pursuant to such final determination, if any, have been paid, any remaining amount of the Indemnity Escrow Amount shall be paid to Seller and Seller and Purchaser shall provide joint written instructions to the Escrow Agent as soon as practicable after such determination to disburse to Seller (or its designee) such amount.

(d) At any time, the Parties may jointly instruct, in the manner provided in the Escrow Agreement, the Escrow Agent to transfer all or a portion of the remaining balance of the Indemnity Escrow Account to either Seller or Purchaser, as the Parties may agree.

(e) Any interest or other income on the Indemnity Escrow Amount shall be allocable to Seller for Tax purposes pursuant to Proposed Treasury Regulation Section 1.468B-8(h)(2), as such Proposed Treasury Regulations may be amended or modified, including upon the issuance of temporary or final regulations.

Accordingly, in the event of any breach of any agreement or covenant set forth in this Agreement (other than under Articles 3 and 4), Purchaser, in the case of a breach by Seller, and Seller, in the case of a breach by Purchaser, may be entitled to equitable relief, without the proof of actual damages, including in the form of an injunction or injunctions or orders for specific performance to prevent breaches of this Agreement and to order the defaulting Party to affirmatively carry out its obligations under this Agreement, and each of the Parties hereby waives any defense to the effect that a remedy at law would be an adequate remedy for such breach. Such equitable relief shall be in addition to any other remedy to which each of the Parties are entitled to at law or in equity as a remedy for such nonperformance, breach or threatened breach. Each of the Parties hereby waives any requirements for the securing or posting of any bond with such equitable remedy. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by any of the Parties, each of whom expressly reserves any and all rights and remedies available to it at law or in equity in the event of any breach or default by the others under this Agreement prior to the Closing.

Section 12.19 Time of Essence. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

Either Seller or Buyer may deliver to the Escrow Agent, with a copy to the non-delivering Interested Party, a certified copy of a final non-appealable judgment or order of a court of competent jurisdiction or a final non-appealable arbitration decision (each, a “Judgment”) awarding all or any part of the Escrow Property to Seller or Buyer, as applicable. Within ten (10) Business Days after receipt of such Judgment, the Escrow Agent shall disburse the Escrow Property (or the applicable portion thereof) as directed by such Judgment.

(a) The Interested Parties agree that, for U.S. federal and applicable state income tax purposes, any earnings or proceeds with respect to the Escrow Property shall be treated as follows: (i) with respect to the Escrow Deposit (to the extent earned prior to Closing), as the income of the Buyer in accordance with Treasury Regulation Section 1.468B-7(c), and (ii) with respect to the Escrow Property held by the Escrow Agent immediately after Closing or deposited with the Escrow Agent by Buyer at or after Closing, as the income of the Seller, pursuant to Proposed Treasury Regulation Section 1.468B-8(h)(2), as such Proposed Treasury Regulations may be amended or modified, including upon the issuance of temporary or final regulations. Any such earnings or proceeds shall be reported on an annual basis by the Escrow Agent on the appropriate United States Internal Revenue Service (“IRS”) Form 1099 (or IRS Form 1042-S), as required pursuant to the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations thereunder.

for U.S. federal or applicable state income tax purposes that is inconsistent with the provisions of this Section 4(a).

(b) If IRS imputed interest requirements apply, the Interested Parties are solely responsible to inform the Escrow Agent, provide the Escrow Agent with all imputed interest calculations, and direct the Escrow Agent to disburse imputed interest amounts. The Escrow Agent shall rely solely on such provided calculations and information and shall have no responsibility for the accuracy or completeness of any such calculations or information or for the failure of the Interested Parties to provide such calculations or information.

(c) The Interested Parties shall upon the execution of this Agreement provide the Escrow Agent with a duly completed and properly executed IRS Form W-9 or applicable IRS Form W-8, in the case of a non-U.S. person, for each payee, together with any other documentation and information reasonably requested by the Escrow Agent in connection with the Escrow Agent’s tax reporting obligations under the Code and the regulations thereunder.

(d) Should the Escrow Agent become liable for the payment of taxes, including withholding taxes relating to any funds, including interest and penalties thereon, held by it pursuant to this Agreement or any payment made hereunder, the Escrow Agent shall satisfy such liability to the extent possible from the Escrow Property. The Interested Parties agree, jointly and severally, to indemnify and hold the Escrow Agent harmless pursuant to Section 6(c) hereof from any liability or obligation on account of taxes, assessments, interest, penalties, expenses and other governmental charges that may be assessed or asserted against the Escrow Agent with respect to the Escrow Property.

(e) The Escrow Agent’s rights under this Section shall survive the termination of this Agreement or the resignation or removal of the Escrow Agent.

5. Concerning the Escrow Agent.

(a) Escrow Agent Duties. Each Interested Party acknowledges and agrees that (i) the duties, responsibilities and obligations of the Escrow Agent shall be limited to those expressly set forth in this Agreement, each of which is administrative or ministerial (and shall not be construed to be fiduciary) in nature, and no duties, responsibilities or obligations shall be inferred or implied, (ii) the Escrow Agent shall not be responsible for any of the agreements referred to or described herein (including without limitation the Purchase Agreement; provided, that in the event of a conflict between this Agreement and the Purchase Agreement, the Purchase Agreement shall control as between Buyer and Seller), or for determining or compelling compliance therewith, and shall not otherwise be bound thereby,

		-3-

and (iii) the Escrow Agent shall not be required to expend or risk any of its own funds to satisfy payments from the Escrow Property hereunder.

(b) Liability of Escrow Agent. The Escrow Agent shall not be liable for any damage, loss or injury resulting from any action taken or omitted in the absence of gross negligence or willful misconduct (as finally adjudicated by a court of competent jurisdiction). In no event shall the Escrow Agent be liable for indirect, incidental, consequential, punitive or special losses or damages (including but not limited to lost profits), regardless of the form of action and whether or not any such losses or damages were foreseeable or contemplated. The Escrow Agent shall be entitled to rely upon any instruction, notice, request or other instrument delivered to it without being required to determine the authenticity or validity thereof, or the truth or accuracy of any information stated therein. The Escrow Agent may act in reliance upon any signature believed by it to be genuine and may assume that any person purporting to make any statement, execute any document, or send any instruction in connection with the provisions hereof has been duly authorized to do so (provided that the Escrow Agent may so act or so assume only after compliance with the telephone callback requirements set forth on Schedule B and Schedule C). The Escrow Agent may consult with counsel satisfactory to it, and the opinion or advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it in good faith and in accordance with the opinion and advice of such counsel. The Escrow Agent may perform any and all of its duties through its agents, representatives, attorneys, custodians and/or nominees. The Escrow Agent shall not incur any liability for not performing any act or fulfilling any obligation hereunder by reason of any occurrence beyond its control (including, without limitation, any provision of any present or future law or regulation or any act of any governmental authority, any act of God or war or terrorism, or the unavailability of the Federal Reserve Bank wire services or any electronic communication facility).

(c) Reliance on Orders. The Escrow Agent is authorized to comply with Judgments issued or final process entered by any court with respect to the Escrow Property, without determination by the Escrow Agent of such court’s jurisdiction in the matter. If any portion of the Escrow Property is at any time attached, garnished or levied upon under any Judgment, or in case the payment, assignment, transfer, conveyance or delivery of any such property shall be stayed or enjoined by any Judgment, or in case any writ, Judgment or decree shall be made or entered by any court affecting such property or any part thereof, then and in any such event, the Escrow Agent is authorized to rely upon and comply with any such writ, Judgment or decree which it is advised by counsel is binding upon it without the need for appeal or other action; and if the Escrow Agent complies with any such writ, Judgment or decree, it shall not be liable to any of the Interested Parties hereto or to any other person or entity by reason of such compliance even though such writ, Judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated.

6. Compensation, Expense Reimbursement and Indemnification.

(a) Compensation. Each of the Interested Parties covenants and agrees, jointly and severally, to pay the Escrow Agent’s compensation specified in Schedule A. Each of the Interested Parties covenants and agrees, jointly and severally, to pay to the Escrow

		-4-

Agent all reasonable and documented out-of-pocket third party expenses actually incurred by the Escrow Agent in the performance of its role under this Agreement after the date hereof, without duplication of any other escrow agreement entered into in connection herewith.

(b) Security and Offset. The Interested Parties hereby grant to the Escrow Agent a first lien upon, and right of offset against, the Escrow Property with respect to any fees or expenses due to the Escrow Agent hereunder (including any claim for indemnification hereunder). In the event that any fees or expenses, or any other obligations owed to the Escrow Agent (or its counsel) are not paid to the Escrow Agent within 30 calendar days following the delivery of an invoice for the payment of such fees and expenses or the written demand for such payment, then the Escrow Agent may, without further action or notice, pay such fees and expenses from the Escrow Property and may sell, convey or otherwise dispose of the Escrow Property (or necessary portion thereof) for such purpose. The Escrow Agent may in its sole discretion withhold from any distribution of the Escrow Property an amount of such distribution it reasonably believes would, upon sale or liquidation, produce proceeds equal to any unpaid amounts to which the Escrow Agent is entitled to hereunder.

(c) Indemnification. Each of the Interested Parties covenants and agrees, jointly and severally, to indemnify the Escrow Agent and its employees, officers, directors, affiliates, and agents (each, an “Indemnified Party”) for, hold each Indemnified Party harmless from, and defend each Indemnified Party against, any and all claims, losses, actions, liabilities, costs, damages and expenses of any nature incurred by any Indemnified Party, arising out of or in connection with this Agreement or with the administration of its duties hereunder, including but not limited to attorney’s fees, costs and expenses, except to the extent such loss, liability, damage, cost or expense shall have been finally adjudicated by a court of competent jurisdiction to have resulted solely from the Indemnified Party’s own gross negligence or willful misconduct. The foregoing indemnification and agreement to hold harmless shall survive the termination of this Agreement and the resignation or removal of the Escrow Agent.

7. Dispute Resolution. In the event of any disagreement among any of the Interested Parties to this Agreement, or between any of them and any other person, resulting in adverse claims or demands being made with respect to the subject matter of this Agreement, or in the event that the Escrow Agent, in good faith, is in doubt as to any action it should take hereunder, the Escrow Agent may, at its option, refuse to comply with any claims or demands and refuse to take any other action hereunder, so long as such disagreement continues or such doubt exists, and in any such event, the Escrow Agent shall not be liable in any way or to any person for its failure or refusal to act, and the Escrow Agent shall be entitled to continue to so refuse to act and refrain from acting until the Escrow Agent shall have received (i) a final non-appealable order, Judgment or decree by a court of competent jurisdiction which resolves the applicable conflict or dispute, or (ii) a written agreement executed by each of the Interested Parties involved in such disagreement, in which case the Escrow Agent shall be authorized to disburse the Escrow Property (or any portion thereof) in accordance with such final court order, Judgment, decree or agreement. The Escrow Agent shall have the option, after 30 calendar days’ notice to the Interested Parties of its intention to do so, to petition (by means of filing an action in interpleader or any

EXHIBIT D

TITLE/ENVIRONMENTAL DISPUTES

All Disputed Matters not finally resolved by the Parties shall be resolved pursuant to this Exhibit D.

(a) Disputed Environmental Matters shall be submitted to a mutually agreed upon nationally recognized independent environmental consulting firm with ten (10) years’ experience as an environmental consultant involving oil and gas properties in the area where the applicable Environmental Defect Property is located (the “Environmental Arbitrator”), and (b) Disputed Title Matters shall be submitted to a mutually agreed upon attorney with at least ten (10) years’ experience as an oil and gas title attorney involving oil and gas properties in the area where the applicable Title Defect Property is located (the “Title Arbitrator” and together with the Environmental Arbitrator, the “Defect Arbitrator”). In the event Purchaser and Seller are unable to mutually agree upon a Defect Arbitrator within twenty (20) days after a Party submitting a matter pursuant to the terms of this Exhibit D, then Seller and Purchaser shall promptly (but in any event within three (3) days after such twentieth (20th) day after a Party’s submission of such matter) nominate a candidate to be the applicable Defect Arbitrator, and such two (2) candidates so nominated shall together within five (5) days elect and determine the applicable Defect Arbitrator (and if such nominated candidates are unable to agree on the Defect Arbitrator within such five (5)-day period, the Defect Arbitrator will be selected by the Houston, Texas office of the American Arbitration Association). The Defect Arbitrator (i) shall not have worked as an employee, consultant, contractor or outside counsel for any Party or any Affiliate of any Party during the five (5)-year period preceding the arbitration or have any financial interest in the dispute, and (ii) shall satisfy the qualifications set forth in (a) or (b) above, as applicable.

The arbitration proceeding shall be conducted in accordance with, but not under the auspices or jurisdiction of, the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Agreement. The applicable Defect Arbitrator’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. With respect to each Disputed Matter, as applicable, the Defect Arbitrator shall rule in favor of either Seller’s position (including as to the amount, if any, owed) with respect to such Disputed Matter or Purchaser’s position (including as to the amount, if any, owed) with respect to such Disputed Matter.

The decision of the Defect Arbitrator shall be rendered in writing and shall be final and binding upon the Parties as to the Disputed Matter. Seller and Purchaser shall each bear their own legal fees and other costs of presenting their case.

The Defect Arbitrator shall not have any authority to award exemplary or punitive damages. The sole forum for the arbitration shall be Harris County, Texas and all hearings shall be conducted in Harris County, Texas. Each Party shall bear one-half of the costs and expenses of arbitration, including reasonable compensation of the Defect Arbitrator.

Neither Seller nor Purchaser subject to this Exhibit D will commence or prosecute any suit or action against the other

D-1

Party subject to this Exhibit D relating to the Disputed Matter, other than as may be necessary to compel arbitration under this Exhibit D or to enforce the award of the board of arbitration.

In making a determination, the applicable Defect Arbitrator shall be bound by the terms set forth in this Agreement with respect to the Title Defects, Title Benefits, Title Defect Amounts, Title Benefit Amounts, Environmental Defects and Environmental Defect Amounts, as applicable, or otherwise and may consider such other matters as in the opinion of the applicable Defect Arbitrator are necessary or helpful to make a proper determination. Additionally, the applicable Defect Arbitrator may consult with and engage any disinterested non-party to advise the arbitrator, including title attorneys from other states and petroleum engineers. The applicable Defect Arbitrator shall act as an expert for the limited purpose of determining the specific Disputed Matter submitted by any Party and may not award damages, interest or penalties to any Party with respect to any matter.

No matters whatsoever, other than the Disputed Matters, are subject to the agreement to arbitrate embodied in this Exhibit D.

Notwithstanding Section 12.6 of this Agreement, Disputed Title Matters shall be governed by and construed in accordance with the Laws of the jurisdiction where the applicable Title Defect Property is located, without regard to principles of conflicts of laws that would direct the application of the Laws of another jurisdiction.
