BUYER’S REPRESENTATIONS AND WARRANTIES

Buyer represents and warrants to Seller as follows:

Section 5.1 Organization and Standing. Buyer is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware and is duly qualified to carry on its business in each State where failure to be so qualified could reasonably be expected to adversely affect the Assets or consummation of the transactions contemplated by this Agreement.

Section 5.2 Legal Power. Buyer has all requisite power and authority to carry on its business as presently conducted and to execute, deliver and perform this Agreement (and all documents required to be executed and delivered by Buyer at Closing). The execution, delivery and performance of this Agreement (and such documents) and the consummation of the transactions contemplated hereby (and thereby) shall not violate, or be in conflict with, any material provision of Buyer’s governing documents or any material provisions of any agreement or instrument to which it is a party or by which it is bound, or, to its knowledge, any judgment, decree, order, statute, rule or regulation applicable to Buyer.

Section 5.3 Authorization and Enforceability. The execution, delivery and performance by Buyer of this Agreement (and all documents required to be executed and delivered by Buyer at Closing), and the consummation of the transactions contemplated hereby

(and thereby), have been duly authorized by all necessary action on behalf of Buyer. This Agreement constitutes (and, at Closing, such documents shall constitute) Buyer’s legal, valid and binding obligation, enforceable against Buyer in accordance with its terms, subject, however, to the effects of bankruptcy, insolvency, reorganization, moratorium and similar laws for the protection of creditors, as well as to general principles of equity, regardless whether such enforceability is considered in a proceeding in equity or at law.

Section 5.4 Liability for Brokers’ Fees. Buyer has not incurred any liability, contingent or otherwise, for brokers’ or finders’ fees relating to the transactions contemplated by this Agreement for which Seller shall have any responsibility whatsoever.

Section 5.5 Litigation. There is no action, suit, proceeding, claim or investigation by any Person or Governmental Authority that impedes or is likely to impede Buyer’s ability to consummate the transactions contemplated hereby.

Section 5.6 Securities Law, Access to Data and Information. Buyer is familiar with the Company Interests and the Assets, is a knowledgeable, experienced and sophisticated investor in the oil and gas business, and is an “accredited investor” as such term is defined in Regulation D of the Securities Act. Buyer understands and accepts the risks and absence of liquidity inherent in ownership of the Company Interests. Buyer acknowledges that the Company Interests may be deemed to be “securities” under the Securities Act and certain applicable State securities or Blue Sky laws, and that resales thereof may therefore be subject to the registration requirements of such acts. The Company Interests are being acquired solely for Buyer’s own account for the purpose of investment and not with a view to resale, distribution or granting a participation therein in violation of any securities Laws.

ARTICLE 6

COVENANTS AND AGREEMENTS

Section 6.1 Covenants and Agreements of Seller. Seller covenants and agrees with Buyer as follows:

(a) Access to Records; Physical Access to the Leases and ▇▇▇▇▇. From the date of this Agreement to the Closing, Seller will and will cause each Company Entity to:

(i) Make the Records available to Buyer and its representatives for inspection and review at Seller’s offices during normal business hours to permit Buyer to perform its due diligence review. Subject to the consent and cooperation of third Persons, Seller will assist Buyer in its efforts to obtain, at Buyer’s expense, such additional information from such Persons as Buyer may reasonably desire. Buyer may inspect the Records and such additional information only to the extent it may do so without violating any obligation of confidence or contractual commitment of a Company Entity or Seller to a third Person. If disclosure or access is prohibited, Seller shall, and shall cause the Company Entities to, use commercially reasonable efforts to obtain permission to grant such access to Buyer and its representatives, and shall provide Buyer and its representatives with as much information or access concerning the matter as is

possible while still complying with applicable Laws and Seller’s and the Company Entities’ obligations; provided that neither any Company Entity nor Seller shall be required to make any payments for the benefit of any third Person in order to do so.

(ii) To the extent Seller has the legal authority to do so, grant Buyer, during reasonable business hours, physical access to the Properties to allow Buyer to conduct, at Buyer’s sole risk and expense, on-site inspections and environmental assessments of the Properties. In connection with any such on-site inspections, Buyer agrees not to unreasonably and materially interfere with the normal operation of the Properties and agrees to comply with all requirements of the operators of the ▇▇▇▇▇. If Buyer or its agents prepare an environmental assessment of any Lease or Well, Buyer agrees to keep such assessment confidential, unless disclosure is required pursuant to applicable Law, and to furnish copies thereof to Seller. IN CONNECTION WITH GRANTING SUCH ACCESS, BUYER REPRESENTS THAT IT IS ADEQUATELY INSURED AND WAIVES, RELEASES AND AGREES TO INDEMNIFY SELLER AND ITS RESPECTIVE DIRECTORS, OFFICERS, MEMBERS, MANAGERS, LIMITED PARTNERS, SHAREHOLDERS, EMPLOYEES, AGENTS, REPRESENTATIVES AND AFFILIATES AGAINST ALL CLAIMS FOR INJURY TO, OR DEATH OF, PERSONS OR FOR DAMAGE TO PROPERTY ARISING IN ANY WAY FROM THE ACCESS AFFORDED TO BUYER HEREUNDER OR THE ACTIVITIES OF BUYER, REGARDLESS OF CAUSE, INCLUDING THE CONCURRENT NEGLIGENCE OF SELLER AND ITS CONTRACTORS AND SUBCONTRACTORS AND THEIR EMPLOYEES, BUT EXCLUDING HOWEVER, THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY SUCH PERSON. THIS WAIVER, RELEASE AND INDEMNITY BY BUYER SHALL SURVIVE TERMINATION OF THIS AGREEMENT.

(iv) Comply in all material respects with all applicable Laws, statutes, ordinances, rules, regulations and orders relating to the Assets;

(v) Maintain the personal property comprising part of the Company-Operated Assets in at least as good a condition as it is on the date hereof, subject to ordinary wear and tear;

(vi) Keep Buyer reasonably informed regarding current and proposed activities and operations relating to the Assets;

(viii) Use commercially reasonable efforts to preserve intact its present business organization and endeavor to preserve its relationships with customers, suppliers and others having business dealings with it to the end that its goodwill and ongoing business shall not be impaired in any material respect at the Closing;

(ix) Keep and maintain accurate books, records and accounts;

(x) Maintain in full force and effect existing insurance policies and binders subject only to variations required by the ordinary course of business, or else will obtain, prior to the lapse of any such policy or binder, substantially similar coverage with insurers of recognized standing;

(xi) Pay all Taxes imposed upon any of its Assets or with respect to its franchises, business, income or assets before any penalty or interest accrues thereon;

(xii) Pay all claims and expenses (including claims and expenses for labor, services, materials and supplies) which are not the subject of a bona fide dispute when they become due and payable in accordance with their terms;

(xiii) Comply with and enforce the provisions of the Material Contracts, including paying when due all Indebtedness, payables, rentals, royalties, expenses and other liabilities relating to its business or Assets which are not the subject of a bona fide dispute; and

(xiv) At all times preserve and keep in full force and effect its corporate existence.

(c) Restriction on Operations. From the date of this Agreement to the Closing, Seller shall not, and shall not permit any Company Entity to, without Buyer’s consent (which shall not be unreasonably withheld):

(i) Take any action that would cause its representations or warranties under this Agreement to be materially incorrect (or with respect to representations and warranties qualified by materiality or material adverse effect, incorrect in any respect) as of the Closing Date;

(ii) Abandon any Company-Operated Asset (except any Leases, after the expiration of its primary term if not capable of producing in paying quantities);

Exhibit B;

(vi) Make any other material change to a division order, revenue deck or expense deck relating to any Company-Operated Asset without written notice to Buyer (for such purposes, a customary change to the ownership of an individual interest arising from a transfer by sale, gift or death shall not constitute a material change);

(vii) Make any written or oral agreement allowing for the use of land covered by the Leases or the Units for mining purposes;

(viii) Sell, lease, encumber or otherwise dispose of all or any part of the Assets (other than replacement of equipment and sales of Hydrocarbons in the ordinary course of business);

Section 6.2 Enforcement of Third Party Provisions.

From the date of this Agreement to the Closing, Seller will cause each Company Entity to, at Buyer’s request, use reasonable efforts to enforce all of its rights against third Persons under any warranties, guarantees or indemnities given by such third Persons.

Section 6.3 Confidentiality.

(a) All data and information, whether written or oral, obtained from Seller or the Company Entities in connection with the transactions contemplated hereby, including

the Records, whether obtained by Buyer before or after the execution of this Agreement, and data and information generated by Buyer based on data or information obtained from Seller or the Company Entities in connection with the transactions contemplated hereby (collectively, the “Information”), is deemed by the Parties to be confidential. Until the Closing, except as required by Law, Buyer and its respective officers, agents and representatives shall hold in strict confidence all Information, except any Information which:

(i) At the time of disclosure by Seller or a Company Entity is in the public domain;

(ii) After disclosure by Seller or a Company Entity becomes part of the public domain by publication or otherwise, except by breach of this commitment by Buyer;

(iii) Buyer can establish was rightfully in its possession at the time of disclosure by Seller or a Company Entity;

(iv) Buyer rightfully received from third Persons free of any obligation of confidence; or

(v) Is developed independently by Buyer without the Information, provided that the Person or Persons developing the data shall not have had access to the Information.

(b) Return of Information. If Closing does not occur and this Agreement is terminated, if Seller so requests at any time, Buyer shall: (i) return to Seller all copies of the Information in its possession obtained pursuant to any provision of this Agreement, which Information is at the time of termination required to be held in confidence pursuant to this Section 6.3; and (ii) destroy any and all notes, reports, studies or analyses based on, or incorporating, the Information. The terms of this Section 6.3 shall survive termination of this Agreement.

Section 6.4 SEC Matters. Seller acknowledges that the Partnership may be required to include financial statements relating to the Company Entities (“SEC Financial Statements”) in documents filed with the SEC by the Partnership pursuant to the Securities Act or the Exchange Act, and that such SEC Financial Statements may be required to be audited. In that regard, Seller shall cooperate with Buyer, and provide Buyer reasonable access to such records (to the extent such information is available) and personnel of Seller as Buyer may reasonably request to enable Buyer, and its representatives and accountants, at Buyer’s sole cost and expense, to create and audit any SEC Financial Statements that Buyer deems necessary. Seller hereby consents to the inclusion or incorporation by reference of the SEC Financial Statements in any registration

statement, report or other document of Buyer or any of its Affiliates to be filed with the SEC in which Buyer or Affiliate reasonably determines that the SEC Financial Statements are required to be included or incorporated by reference to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act. Upon request of Buyer, Seller shall use commercially reasonable efforts to cause the external audit firm that audits the SEC Financial Statements to consent to the inclusion or incorporation by reference of its audit opinion with respect to the audited Financial Statements in any such registration statement, report or other document.

If Seller opts to exclude any such affected Assets (collectively, the “Retained Assets”), Seller shall cause the applicable Company Entity to assign such Retained Assets to Seller before Closing. If Seller opts not to exclude such affected Assets, Buyer shall nevertheless be required to close, and Seller shall elect, by written notice to Buyer prior to Closing, in the case of fire or other casualty, either (A) to cause the such affected Assets affected to be repaired or restored to at least their condition prior to such Casualty Loss, at Seller’s sole cost, risk and expense, as promptly as reasonably practicable (which work may extend after the Closing Date), or (B) to indemnify Buyer and the Company Entities in a manner reasonably acceptable to Buyer against any Losses that Buyer or any Company Entity reasonably incurs to repair such affected Assets. In the case of condemnation or eminent domain, the Parties shall work together in good faith to reduce the Purchase Price by an amount equal to the Allocated Value (or applicable portion thereof) of the Assets (or portion thereof) taken in condemnation or under right of eminent domain. In each case, the applicable Company Entity shall retain all rights to insurance and other claims against third Persons with respect to the Casualty Loss, except to the extent the Parties otherwise agree in writing.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets experiences a Casualty Loss, and the loss as a result of such Casualty Loss individually or in the aggregate is 1% or less of the unadjusted Purchase Price, Buyer shall nevertheless be required to close and Seller shall, at Closing, pay to Buyer all sums (if any) paid to Seller by third Persons by reason of such Casualty Loss and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third Persons arising out of such Casualty Loss.

Section 6.6 Further Assurances. Each Party shall (and, where applicable, shall cause the Company Entities to) use its respective commercially reasonable efforts to obtain all approvals and consents required by or necessary for the transactions contemplated hereby, and to ensure that all of the conditions to its respective obligations contained in Article 7 or Article 8, as applicable, are satisfied as soon as reasonably practicable.

Section 6.7 Intercompany Accounts and Affiliate Transactions.

(a) At or prior to the Closing, Seller shall cause to be settled, repaid or canceled all intercompany accounts that are unpaid as of the Closing Date between any Company Entity, on the one hand, and Seller or any of its Affiliates, on the other hand, in each case at no cost to the Company Entity.

(b) At or prior to the Closing, Seller shall have caused to be terminated, at no cost to and without creating any Obligations for the Company Entity, all contracts between any Company Entity, on the one hand, and Seller or any of its Affiliates, on the other hand.

Reasonably in advance of filing, which shall be at least 10 days prior to the due date for filing any such Straddle Tax Return, the Partnership shall deliver a copy of each such Straddle Tax Return, together with all supporting documentation and workpapers, to Seller for its review and reasonable comment. The Partnership will cause each such Straddle Tax Return (as revised to incorporate Seller’s reasonable comments) to be timely filed and will provide a copy to Seller. At least five days prior to the due date for payment of Taxes with respect to any Straddle Tax Return, Seller shall pay to the Partnership the amount of any Taxes with respect to such Straddle Tax Return that are attributable (as determined below) to periods prior to the Balance Sheet Date to the extent such Taxes were not included as a liability on the balance sheet as of the Balance Sheet Date delivered as part of the Financial Statements.

(iv) For purposes of the foregoing, the following provisions shall apply:

(A) In the case of any Tax that is based on income, sales, revenue, production or similar items, and that pertains or is attributable to any period that includes (but does not end on) the Balance Sheet Date, the amount of such Tax attributable to the period prior to the Balance Sheet Date shall be determined based on an interim closing of the books as of the close of business on the Balance Sheet Date.

(B) In the case of any other Tax, including real property, personal property, ad valorem and similar Taxes, attributable to any period that includes (but does not end on) the Balance Sheet Date, the amount of such Tax attributable to the period prior to the Balance Sheet Date shall be the amount of such Tax multiplied by a fraction, the numerator of which is the number of days in the portion of such period ending on the Balance Sheet Date and the denominator of which is the total number of days in such period.

(b) Each Party shall use commercially reasonable efforts to cooperate fully with the other Party, as and to the extent reasonably requested by the other Party and at the requesting Party’s expense, in connection with the filing of Tax Returns and any proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such proceeding and making employees (to the extent such employees were responsible for the preparation, maintenance or interpretation of information and documents relevant to Tax matters or to the extent required as witnesses in any Tax proceedings), available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Each Party agrees to retain all of its books and records with respect to Tax matters pertinent to the Company Entities relating to any taxable period beginning before the Closing Date until the expiration of the applicable statute of limitations and to abide by all record retention agreements entered into with any Governmental Authority.

(c) All sales, use or other Taxes (other than Taxes on gross income, net income or gross receipts) and duties, levies or other governmental charges incurred by or imposed with respect to the transfer to Buyer undertaken pursuant to this Agreement shall be the responsibility of, and shall be paid by, Buyer.

(d) If notice of any audit, examination or other proceeding with respect to Taxes of the Company (a “Tax Claim”) shall be received by either Party for which the other Party may be reasonably expected to be liable pursuant to Article 11, the notified Party shall notify such other Party in writing of such Tax Claim; provided, however, that the failure of the notified Party to give the other Party notice as provided herein shall not relieve such failing Party of its obligations under Article 11, except to the extent the other Party is actually and materially prejudiced thereby.

In the event that the Parties cannot reach agreement within such period of time, any Party may refer the items adjustment which are in dispute to a nationally-recognized independent accounting firm or consulting firm mutually acceptable to both Buyer and Seller (the “Accounting Arbitrator”), for review and final determination by arbitration. The Accounting Arbitrator shall conduct the arbitration proceedings in Houston, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 9.3. The Accounting Arbitrator’s determination shall be made within 45 days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal. In determining the proper amount of any adjustment to the Purchase Price, the Accounting Arbitrator shall be bound by the terms of this Agreement and may not increase the Purchase Price more than the increase proposed by Seller nor decrease the Purchase Price more than the decrease proposed by Buyer, as applicable. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific disputed aspects of Purchase Price adjustments submitted by any Party and may not award damages, interest or penalties to any Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Seller shall bear one-half and Buyer shall bear one-half of the costs and expenses of the Accounting Arbitrator. Within ten days after the earlier of (i) the expiration of Buyer’s 30 day review period without delivery of any written report or (ii) the date on which the Parties or the Accounting Arbitrator finally determine the Purchase Price, Buyer shall pay to Seller the amount by which the Purchase Price exceeds the amount paid pursuant to Section 9.3(a) or Seller shall pay to Buyer the amount by which the amount paid pursuant to Section 9.3(a) exceeds the Purchase Price, as applicable. Any post-Closing payment pursuant to this Section 9.3 shall bear interest from the Closing Date to the date of payment at the lesser of (x) the annual rate of interest published as the “Prime Rate” in the “Money Rates” section of The Wall Street Journal on the last Business Day prior to the Effective Date plus 3% and (y) the maximum rate allowed by applicable Law.

Section 11.3 Limitations for Seller’s Indemnification.

(a) Time Limitations. Notwithstanding anything to the contrary herein:

(i) Seller’s indemnification obligations under Section 11.2(b) and Section 11.2(c) shall only apply with respect to any breach of any representation or warranty if Buyer has provided Seller with written notice claiming indemnification therefor on or before the date on which such representation or warranty expires pursuant to Section 12.3;

(ii) Seller’s indemnification obligations under Sections 11.2(d) and (e) shall only apply to any claim thereunder if Buyer has provided Seller with written notice claiming indemnification for such claim on or before 9 months after the Closing Date; and

(iii) Seller’s indemnification obligations under Section 11.2(f) shall only apply to any claim thereunder if Buyer has provided Seller with written notice claiming indemnification for such claim on or before the 60th day after the expiration of any applicable statute of limitations.

(b) Deductible. Notwithstanding anything to the contrary herein, no claim may be made against Seller for indemnification under Section 11.2(c) until the aggregate dollar amount of the Material Losses suffered or incurred by Buyer for which Buyer would otherwise be entitled to indemnification thereunder exceeds 2% of the unadjusted Purchase Price; after such ▇▇▇▇ ▇▇▇▇▇▇ shall be liable to the extent and only to the extent that the aggregate amount of such Material Losses exceeds 2% of the unadjusted Purchase Price. The term “Material Losses” means only those Losses that exceed $25,000.

(c) Cap. Notwithstanding anything to the contrary herein, Seller’s aggregate liability under Section 11.2(c) shall not exceed 20% of the unadjusted Purchase Price.

(d) Notwithstanding anything to the contrary in this Agreement, any representation or warranty in Article 4 or Article 5 that is qualified by terms such as “material,” “materiality,” “material adverse effect,” or “in any material respect” or similar qualifying language shall be deemed not to be so qualified for purposes of indemnification pursuant to this Section 11.3. The Parties shall treat, for Tax purposes, any amounts paid pursuant to this Article 11 as an adjustment to the Purchase Price.

Section 11.4 Notices and Defense of Indemnified Matters.

(a) Each Party seeking indemnification (each, an “Indemnified Party”) pursuant to this Article 11 agrees that within a reasonable period of time after it shall become aware of facts giving rise to a claim for indemnification pursuant to this Article 11, it will provide notice thereof in writing to the Parties from whom indemnification is sought pursuant to this Article 11 (each, an “Indemnifying Party”) specifying the nature of and specific basis for such claim; provided, however, that failure to timely provide such notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification set forth in this Article 11, including the selection of counsel (provided that such counsel shall be reasonably acceptable to the Indemnified Parties), determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Parties unless it includes a full release of the Indemnified Parties and their respective Subsidiaries from such matter or issues, as the case may be.

(c) The Indemnified Parties agree to cooperate fully with the Indemnifying Parties with respect to all aspects of the defense of any claims covered by the indemnification set forth in Article 11, including the prompt furnishing to the Indemnifying Parties of any correspondence or other notice relating thereto that the Indemnified Parties may receive, permitting the names of the Indemnified Parties to be utilized in connection with such defense, the making available to the Indemnifying Parties of any files, records or other information of the Indemnified Parties that Indemnifying Parties consider relevant to such defense and the making available to Indemnifying Parties of any employees of the Indemnified Parties; provided, however, that in connection therewith Indemnifying Parties agree to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Parties and further agrees to reasonably maintain the confidentiality of all files, records and other information furnished by the Indemnified Parties pursuant to this Section 11.4. In no event shall the obligation of the Indemnified Parties to cooperate with Indemnifying Parties as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Parties an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article 11; provided, however, that the Indemnified Parties may, at their option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Parties agree to keep any such counsel hired by the Indemnified Parties reasonably informed as to the status of any such defense, but Indemnifying Parties shall have the right to retain sole control over such defense.

(d) In determining the amount of any Losses for which the Indemnified Parties are entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Parties, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Parties as a result of such claim and (ii) all amounts recovered by the Indemnified Parties under contractual indemnities from third parties. The Indemnified Parties hereby agree to use commercially reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under such contractual indemnities; provided, however, that the costs and expenses (including court costs and reasonable attorneys’, accountants’, and experts’ fees) of the Indemnified Parties in connection with such efforts shall be promptly reimbursed by the Indemnifying Parties. To the extent that Indemnifying Parties have made any indemnification payment hereunder in respect of a claim for which the Indemnified Parties have asserted a related claim for insurance proceeds or under a contractual indemnity, Indemnifying Parties shall be subrogated to the rights of the Indemnified Parties to receive the proceeds of such insurance or contractual indemnity.

(a) Except as expressly set forth otherwise in this Section 13.4, no supplement, amendment, alteration, modification or waiver of this Agreement shall be binding unless executed in writing by the Parties and specifically referencing this Agreement and identified as a supplement, amendment, alteration, modification or waiver.

(b) Notwithstanding the foregoing, if a Party becomes aware at any time before the Closing that a Schedule previously delivered by such Party was inaccurate or incomplete when delivered or has become inaccurate or incomplete as a result of subsequent events, such Party shall deliver to the other Party no later than ten Business Days after such discovery (but in any event no later than five days prior to the Closing Date) an amendment or supplement to such Schedule; provided, however, that:

(i) If such amendment or supplement is based on events or matters that arose before the date of this Agreement, no such amendment or supplement shall be given effect for purposes of determining the fulfillment of the conditions precedent set forth in Article 8, unless Seller agrees to indemnify the Buyer Indemnitees for all Losses with respect to such events or matters;

(ii) If such amendment or supplement is based on events or matters that arise after the date of this Agreement and that are expressly permitted to occur under Article 6, such amendment or supplement shall be immediately effective and the Schedules shall be read for all purposes as so amended or supplemented;

(iii) If such amendment or supplement is based on events or matters that arise after the date of this Agreement and such events or matters are not expressly permitted under Article 6 and such events or matters would reasonably be expected to result in Losses (if the Closing were to occur) to the Buyer Indemnitees of greater than or equal to 2% of the unadjusted Purchase Price, such amendment or supplement shall be given effect for purposes of determining the fulfillment of the conditions precedent set forth in Article 8 only if Seller agrees (in Seller’s sole discretion) to indemnify the Buyer Indemnitees for all Losses with respect to such events or matters; and

(iv) If such amendment or supplement is based on events or matters that arise after the date of this Agreement, such events are not expressly permitted under Article 6, and such events or matters would reasonably be expected to result in Losses (if the Closing were to occur) to the Buyer Indemnitees of less than 2% of the unadjusted Purchase Price, such amendment or supplement shall be given effect for determining the fulfillment of the conditions precedent set forth in Article 8 and Seller shall indemnify the Buyer Indemnitees for all Losses with respect to such events or matters.

Section 13.5 Waiver. No waiver or consent, express or implied, by any Party of or to any breach or default by any Person in the performance by such Person of its obligations hereunder shall be deemed or construed to be a consent or waiver of or to any other breach or default in the performance by such Person of the same or any other obligations of such Person hereunder. Failure on the part of a Party to complain of any act of any Person or to declare any Person in default, irrespective of how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder until the applicable statute of limitations period has run.

Section 13.6 Publicity. The Parties hereto shall consult with each other and no Party shall issue any public announcement or statement with respect to this Agreement or the transactions contemplated hereby without the consent of the other Parties, unless such announcement or statement is required by applicable law or stock exchange requirements.

Any assignment by any Party as permitted hereby shall not relieve such Party from any liability hereunder.

Section 13.9 Governing Law; Venue. This Agreement, other documents delivered pursuant hereto and the legal relations between the Parties shall be governed by and construed and enforced in accordance with the laws of the State of Texas, without giving effect to principles of conflicts of law that would result in the application of the laws of another jurisdiction.
