may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

Section 4.07. Certain Fees. No fees or commissions will be payable by such Purchaser to brokers, finders or investment bankers with respect to the sale of any of the Purchased Common Stock or the consummation of the transactions contemplated by this Agreement. Concho will not be liable for any such fees or commissions. Such Purchaser agrees, severally and not jointly with the other Purchasers, that it will indemnify and hold harmless Concho from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by such Purchaser or alleged to have been incurred by such Purchaser in connection with the purchase of Purchased Common Stock or the consummation of the transactions contemplated by this Agreement.

Section 4.08. Legend. It is understood that the certificates evidencing the Purchased Common Stock initially will bear the following legend: “These securities have not been registered under the Securities Act of 1933, as amended. These securities may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or pursuant to an exemption from registration thereunder and, in the case of a transaction exempt from registration, unless sold pursuant to Rule 144 under such Act or the issuer has received documentation reasonably satisfactory to it that such transaction does not require registration under such Act.”

Section 4.09. No Side Agreements. Except for the confidentiality agreements entered into by and between such Purchaser and Concho, there are no other agreements by, among or between Concho or its Affiliates, on the one hand, and such Purchaser or its Affiliates, on the other hand, with respect to the transactions contemplated hereby nor promises or inducements for future transactions between or among any of such parties.

Section 4.10. Short Selling. Such Purchaser represents that it has not entered into any Short Sales of the Common Stock between the time it first began discussions with Concho or the Placement Agents about the transactions contemplated by this Agreement and the date hereof (it being understood that the entering into a total return swap that is exempt from registration under the Securities Act should not be considered a Short Sale of Common Stock).

ARTICLE V
COVENANTS

Section 5.01. Subsequent Public Offerings. Without the written consent of the holders of a majority of the Purchased Common Stock, taken as a whole, from the date of this Agreement until the Lock-Up Date, Concho shall not, and shall cause its directors, officers and Affiliates that are under the control of Concho not to, grant, issue or sell any Common Stock or other equity or voting securities of Concho other than officers entering into 10b5-1 trading plans, any securities convertible into or exchangeable therefore or take any other action that may result in the issuance of any of the foregoing, other than (i) the issuance of the Purchased Common Stock, (ii) the issuance of Awards (as defined in Concho’s Long-Term Incentive Plan) or the issuance of Common Stock upon the exercise of options to purchase Common Stock granted

pursuant to Concho’s existing Long-Term Incentive Plan or (iii) pursuant to the Chase Registration Rights Agreement. Notwithstanding the foregoing, Concho shall not, and shall cause its directors, officers and Affiliates not to, sell, offer for sale or solicit offers to buy any security (as defined in the Securities Act) that would be integrated with the sale of the Purchased Common Stock in a manner that would require the registration under the Securities Act of the sale of the Purchased Common Stock to the Purchasers.

Section 5.02. Taking of Necessary Action. Each of the Parties hereto shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement. Without limiting the foregoing, Concho and each Purchaser will, and Concho shall cause each of its Subsidiaries to, use its commercially reasonable efforts to make all filings and obtain all consents of Governmental Authorities that may be necessary or, in the reasonable opinion of the Purchasers or Concho, as the case may be, advisable for the consummation of the transactions contemplated by this Agreement and the other Basic Documents.

Section 5.03. Non-Disclosure; Interim Public Filings. Concho shall, on or before 8:30 a.m., New York time, on or before the second Business Day following execution of this Agreement, issue a press release acceptable to the Purchasers disclosing all material terms of the transactions contemplated hereby, but excluding the material terms of the Basic Documents. Before 8:30 a.m., New York time, on or before the second Business Day following the date of this Agreement, Concho shall file a Current Report on Form 8-K with the Commission (the “8-K Filing”) describing the terms of the transactions contemplated by this Agreement and the other Basic Documents and including as exhibits to such 8-K Filing this Agreement and the other Basic Documents, in the form required by the Exchange Act. Thereafter, Concho shall timely file any filings and notices required by the Commission or applicable Law with respect to the transactions contemplated hereby and provide copies thereof to the Purchasers promptly after filing. Except with respect to the 8-K Filing and the press release referenced above (a copy of which will be provided to the Purchasers for their review as early as practicable prior to its filing), Concho shall, at least two (2) Business Days prior to the filing or dissemination of any disclosure required by this Section 5.03, provide a copy thereof to the Purchasers for their review. Concho and the Purchasers shall consult with each other in issuing any press releases or otherwise making public statements or filings and other communications with the Commission or any regulatory agency or The New York Stock Exchange (or other exchange on which securities of Concho are listed or traded) with respect to the transactions contemplated hereby, and neither Party shall issue any such press release or otherwise make any such public statement, filing or other communication without the prior consent of the other, except if such disclosure is required by Law, in which case the disclosing Party shall promptly provide the other Party with prior notice of such public statement, filing or other communication. Notwithstanding the foregoing, Concho shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any press release, without the prior written consent of such Purchaser except to the extent the names of the Purchasers are included in this Agreement as filed as an exhibit to the 8-K Filing and the press release referred to in the first sentence above. Concho shall not, and shall cause each of its respective Representatives not to, provide any Purchaser with any material non-public information regarding Concho from and after the issuance of the above-referenced press release without the express written consent of such Purchaser.

Section 5.04. Use of Proceeds. Concho shall use the collective proceeds from the sale of the Purchased Common Stock to partially finance the Xxxxx Acquisition.

Section 5.05. Tax Information. Concho shall cooperate with the Purchasers and provide the Purchasers with any reasonably requested tax information related to their ownership of the Purchased Common Stock.

Section 5.06. Short Selling Acknowledgement and Agreement. Each Purchaser understands and acknowledges, severally and not jointly with any other Purchaser, that the Commission currently takes the position that coverage of short sales of securities “against the box” prior to the effective date of a registration statement is a violation of Section 5 of the Securities Act. Each Purchaser agrees, severally and not jointly, that it will not engage in any Short Sales that result in the disposition of the Common Stock acquired hereunder by the Purchaser until such time as the Registration Statement (as defined in the Registration Rights Agreement) is declared effective. No Purchaser makes any representation, warranty or covenant hereby that it will not engage in Short Sales in the securities of Concho otherwise owned by such Purchaser or borrowed from a broker after the date the press release contemplated by this Agreement is issued by Concho.

ARTICLE VII
INDEMNIFICATION, COSTS AND EXPENSES

Section 7.01. Indemnification by Concho. Concho agrees to indemnify each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon

demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to (i) any actual or proposed use by Concho of the proceeds of any sale of the Purchased Common Stock or (ii) the breach of any of the representations, warranties or covenants of Concho contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty.

Section 7.02. Indemnification by Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify Concho and its Representatives (collectively, “Concho Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to the breach of any of the covenants of such Purchaser contained herein.

Section 7.03. Indemnification Procedure. Promptly after any Concho Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action or proceeding by a third party, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel

reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party.

ARTICLE VIII

Section 8.07. Removal of Legend. Concho shall remove the legend described in Section 4.08 from the certificates evidencing the Purchased Common Stock at the request of a Purchaser submitting to Concho such certificates, together with such other documentation as may be reasonably requested by Concho or required by its transfer agent, unless Concho, with the advice of counsel, reasonably determines that such removal is inappropriate; provided that no opinion of counsel shall be required in the event a Purchaser is effecting a sale of such Purchased Common Stock pursuant to Rule 144 under the Securities Act or an effective registration statement. Concho shall cooperate with such Purchaser to effect removal of such legend. The legend described in Section 4.08 shall be removed and Concho shall issue a certificate without such legend to the holder of Purchased Common Stock upon which it is stamped, if, unless otherwise required by state securities Laws, (i) such shares of Purchased Common Stock are sold pursuant to an effective Registration Statement, (ii) in connection with a sale, assignment or other transfer, such holder provides Concho with an opinion of a law firm reasonably acceptable to Concho (with any law firm set forth under Section 8.06 being deemed acceptable), in a generally acceptable form, to the effect that such sale, assignment or transfer of such Purchased Common Stock may be made without registration under the applicable requirements of the Securities Act, or (iii) such holder provides Concho with reasonable assurance that such Purchased Common Stock can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A under the Securities Act. If Concho shall fail for any reason or for no reason to issue to the holder of such Purchased Common Stock within three trading days after the occurrence of any of clause (i), clause (ii) or clause (iii) above a certificate without such legend to the holder or if Concho fails

to deliver unlegended Purchased Common Stock within three trading days of the Purchaser’s election to receive such unlegended Purchased Common Stock pursuant to clause (y) below, and if on or after such trading day the holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the holder of such Purchased Common Stock that the holder anticipated receiving without legend from Concho (a “Buy-In”), then Concho shall, within three (3) Business Days after the holder’s request and in the holder’s discretion, either (x) pay cash to the holder in an amount equal to the holder’s total purchase price (including brokerage commissions, if any) for the Common Stock so purchased (the “Buy-In Price”), at which point Concho’s obligation to deliver such unlegended Purchased Common Stock shall terminate, or (y) promptly honor its obligation to deliver to the holder such unlegended Purchased Common Stock as provided above and pay cash to the holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock times (B) the closing bid price on the date of exercise.

Section 8.08. Entire Agreement. This Agreement and the other Basic Documents are intended by the Parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the Parties hereto and thereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein with respect to the rights granted by Concho or a Purchaser set forth herein or therein. This Agreement and the other Basic Documents supersede all prior agreements and understandings between the Parties with respect to such subject matter.

Section 8.09. Governing Law. This Agreement will be construed in accordance with and governed by the Laws of the State of Delaware without regard to principles of conflicts of Laws.

Section 8.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different Parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 8.11. Termination.

(a) Notwithstanding anything herein to the contrary, this Agreement may be terminated on or any time prior to the Closing:

(i) by the mutual written consent of the Purchasers entitled to purchase a majority of the Purchased Common Stock based on their Commitment Amounts and Concho; or

(ii) by the written consent of the Purchasers entitled to purchase a majority of the Purchased Common Stock based on their Commitment Amounts or by Concho, (i) if any representation or warranty of the other Party set forth in this Agreement shall be untrue in any material respect when made, or (ii) upon a breach in any material respect of any covenant or agreement on the part of the other set forth in this Agreement (either (i) or (ii) above being a “Terminating Breach”); provided, that, each Terminating Breach

would cause the conditions to the non-terminating Party’s obligations not to be satisfied and such Terminating Breach is not cured within 20 days after written notice from the non-breaching Party.

(b) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate on or any time prior to the Closing:

Schedule 2.01

Exhibit A

Capitalized terms used but not defined herein have the meaning assigned to such terms in the Common Stock Purchase Agreement dated as of June 5, 2008 (the “Purchase Agreement”). Concho shall furnish to the Purchasers at the Closing an opinion of Xxxxxx & Xxxxxx L.L.P., counsel for Concho, addressed to the Purchasers and dated the Closing Date in form satisfactory to [•], counsel for the Purchasers, stating that:

(i) Concho: (i) is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, has requisite power and authority to carry on its business as now conducted, and to own and lease its properties and other assets as now owned or leased, and has all material governmental licenses, authorizations, consents and approvals, necessary to own its properties and carry on its business as its business is now being conducted as described in the Concho SEC Documents, except where the failure to obtain such licenses, authorizations, consents and approvals would not reasonably be expected to have a Concho Material Adverse Effect; and (ii) is duly qualified to do business in the jurisdictions listed in Annex A hereto, except where failure so to qualify would not reasonably be expected to have a Concho Material Adverse Effect.

(ii) As of the open of business on the date hereof, and prior to the issuance and sale of the Purchased Common Stock, the issued and outstanding shares of Common Stock of Concho consists of 75,984,526 shares. All of the outstanding Common Stock have been duly authorized and validly issued in accordance with applicable Law and the Organizational Documents and are fully paid and non-assessable.

(iii) To our knowledge, except as described in the Concho SEC Documents filed prior to the date hereof, for options granted pursuant to Concho’s existing Long-Term Incentive Plan or as contemplated by the Purchase Agreement, there are no outstanding or authorized (i) options, warrants, preemptive rights, subscriptions, calls or other rights, convertible securities, agreements, claims or commitments of any character obligating Concho or any of its Subsidiaries to issue, transfer or sell any equity interests in Concho or any of its Subsidiaries or securities convertible into or exchangeable for such equity interests, (ii) obligations of Concho or any of its Subsidiaries to repurchase, redeem or otherwise acquire any equity interests in Concho or any of its Subsidiaries or any such securities or agreements listed in clause (i) of this sentence or (iii) voting trusts or similar agreements to which Concho or any of its Subsidiaries is a party with respect to the voting of the equity interests of Concho or any of its Subsidiaries.

(iv) The Purchased Common Stock has been duly authorized by Concho pursuant to the Organizational Documents and, when issued and delivered to the Purchasers against payment therefor in accordance with the terms of the Purchase Agreement, will be validly issued, fully paid and non-assessable.

Exhibit A-1

(v) None of the offering, issuance and sale by Concho of the Purchased Common Stock or the execution, delivery and performance of the Basic Documents by Concho (A) constitutes or will constitute a violation of the Organizational Documents, (B) without duplication of clause (A), constitutes or will constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such an event), any agreement filed as an exhibit to the Concho SEC Documents, or (C) results or will result in any violation of the DGCL, the Laws of the State of New York or U.S. federal Law, which in the case of clause (B) or (C) of this paragraph (v) would be reasonably expected to have a Concho Material Adverse Effect; provided, however, that no opinion is expressed pursuant to this paragraph (vi) with respect to federal or state securities or anti-fraud statutes, rules or regulations.

(vi) Each of the Basic Documents to which Concho is a party has been duly authorized and validly executed and delivered on behalf of Concho, and is enforceable against Concho in accordance with its respective terms, except as such enforceability may be limited by (A) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar Laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable Law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

(vii) Except for the approvals required by the Commission in connection with Concho’s obligations under the Registration Rights Agreement (including the registration statement referenced therein), no authorization, consent, approval, waiver, license, qualification or written exemption from, nor any filing, declaration, qualification or registration with, any Governmental Authority is required in connection with the execution, delivery or performance by Concho of any of the Basic Documents to which it is a party, except those that have been obtained or may be required under the state securities or “blue sky” laws, as to which we do not express any opinion.

(vii) Concho is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(ix) Assuming the accuracy of the representations and warranties of each Purchaser contained in the Purchase Agreement, the issuance and sale of the Purchased Common Stock pursuant to the Purchase Agreement are exempt from registration requirements of the Securities Act of 1933, as amended.

Concho shall furnish to the Purchasers at the Closing an opinion of Xxxxx X. Xxxxxxxx, General Counsel of Concho, addressed to the Purchasers and dated the Closing Date in form satisfactory to [•], counsel for the Purchasers, stating that:

Exhibit A-2

(i) None of the offering, issuance and sale by Concho of the Purchased Common Stock or the execution, delivery and performance of the Basic Documents by Concho (A) constitutes or will constitute a violation of any organizational documents of any of Concho’s Subsidiaries or (B) will result in a breach or violation (and, to such counsel’s knowledge, no event has occurred that, with notice or lapse of time or otherwise, would constitute such an event) or imposition of any lien, charge or encumbrance upon any Property of Concho or its Subsidiaries pursuant to (i) any agreement, lease or other instrument known to such counsel (excluding any agreement filed as an exhibit to the Concho SEC Documents) or (ii) to the knowledge of such counsel, any order, judgment, decree or injunction of any federal or Delaware court or government agency or body directed to any of Concho or its Subsidiaries or any of its respective Properties in a proceeding to which any of them or such Property is a party, which breaches, violations or liens would reasonably be expected to have a Concho Material Adverse Effect; provided, however, that no opinion is expressed pursuant hereto with respect to federal or state securities Laws or other anti-fraud Laws.

(ii) All of the issued and outstanding equity interests of each of Concho’s Subsidiaries are owned, directly or indirectly, by Concho free and clear of any Liens (A) in respect of which a financing statement under the Uniform Commercial Code naming Concho or any of its Subsidiaries as debtors is on file in the office of the Secretary of State of the State of Delaware, (B) otherwise known to such counsel without independent investigation, other than those created under applicable Law and (C) except for such Liens as may be imposed under Concho’s or its Subsidiaries’ credit facilities, and all such ownership interests have been duly authorized and validly issued and are fully paid (to the extent required by the organizational documents of Concho’s Subsidiaries, as applicable) and non-assessable (except as non-assessability may be affected by the organizational documents of Concho’s Subsidiaries) and free of preemptive rights, and, to our knowledge, except as disclosed in the Concho SEC Documents, neither Concho nor any of its Subsidiaries owns any shares of capital stock or other securities of, or interests in, any other Person or is obligated to make any capital contribution to or other investment in any other Person.

ARTICLE II
REGISTRATION RIGHTS

Section 2.01 Registration.

(a) Registration.

(i) Deadline To Go Effective. Within sixty (60) days of Concho first becoming eligible to file a registration statement on Form S-3; provided in no event shall such date be later than November 1, 2008 (the “File Date”), Concho shall prepare and file a registration statement under the Securities Act to permit the resale of the Registrable Securities from time to time, including as permitted by Rule 415 under the Securities Act (or any similar provision then in force) under the Act with respect to all of the Registrable Securities (the “Registration Statement”). A Registration Statement filed pursuant to this Section 2.01 shall be on such appropriate registration form of the Commission as shall be selected by Concho. Concho will use its commercially reasonable efforts to cause the Registration Statement filed pursuant to this Section 2.01 to be continuously effective under the Securities Act until the earlier of (i) the date as of which all such Registrable Securities are sold by the Purchasers or (ii) the date when such Registrable Securities become eligible for resale under Rule 144(b) (or any similar provision then in force) under the Securities Act (the “Effectiveness Period”). The Registration Statement when declared effective (including the documents incorporated therein by reference) shall comply as to form with all applicable requirements of the Securities Act and the Exchange Act and shall not contain an 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.

(ii) Failure To Go Effective. If the Registration Statement required by Section 2.01 of this Agreement is not declared effective within 30 days after the File Date, then each Purchaser shall be entitled to a payment with respect to the Purchased Common Stock of each such Purchaser, as liquidated damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier per 30-day period for the first 30 days following the 30^th day after the File Date, increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-day period for each subsequent 30 days, up to a maximum of 1.00% of the Liquidated Damages Multiplier per 30-day period (the “Liquidated Damages”). Initially there shall be no limitation on the aggregate amount of the Liquidated Damages payable by Concho under this Agreement to each Purchaser; provided, however, that if there is a change in the Law or accounting principles generally accepted in the United States that would result in the Purchased Common Stock being treated as debt securities instead of equity securities for purposes of Concho’s financial statements, then the aggregate amount of the Liquidated Damages payable by Concho under this Agreement to each Purchaser shall not exceed the maximum amount of the Liquidated Damages Multiplier with respect to such Purchaser allowed for the Purchased Common Stock not to be treated as debt securities for purposes of Concho’s financial statements. The Liquidated Damages payable pursuant to the immediately preceding sentence, accrued on a daily basis, shall

Exhibit B-3

be payable within ten Business Days of the end of each such 30-day period. Any Liquidated Damages shall be paid to each Purchaser in cash or immediately available funds; provided, however, if Concho certifies that it is unable to pay Liquidated Damages in cash or immediately available funds because such payment would result in a breach under any of Concho’s or Concho’s Subsidiaries’ credit facilities or other indebtedness filed as exhibits to the Concho SEC Documents, then, to the extent not payable in cash, Concho may pay the Liquidated Damages in kind in the form of the issuance of additional shares of Common Stock. Upon any issuance of Common Stock as Liquidated Damages, Concho shall promptly prepare and file an amendment to the Registration Statement prior to its effectiveness adding such Common Stock to such Registration Statement as additional Registrable Securities. The determination of the amount of Common Stock to be issued as Liquidated Damages shall be equal to the amount of Liquidated Damages divided by the volume weighted average closing price of the Common Stock (as reported by The New York Stock Exchange) for the ten (10) trading days immediately preceding the date on which the Liquidated Damages payment is due. The payment of Liquidated Damages to a Purchaser shall cease at such time as the Purchased Common Stock of such Purchaser become eligible for resale under Rule 144(b) under the Securities Act. As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two Business Days of such date, Concho shall provide the Purchasers with written notice of the effectiveness of the Registration Statement.

(iii) Waiver of Liquidated Damages. If Concho is unable to cause a Registration Statement to go effective within 30 days following the File Date as a result of an acquisition, merger, reorganization, disposition or other similar transaction, then Concho may request a waiver of the Liquidated Damages, which may be granted or withheld by the consent of the Holders of a majority of the Purchased Common Stock, taken as a whole, in their sole discretion. A Purchaser’s rights (and any transferee’s rights pursuant to Section 2.10 of this Agreement) under this Section 2.01 other than Liquidated Damages owing but not yet paid shall terminate upon the earlier of (i) when all such Registrable Securities are sold by such Purchaser or transferee, as applicable, and (ii) when such Registrable Securities become eligible for resale under Rule 144(b) (or any similar provision then in force) under the Securities Act.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, Concho may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement, but such Selling Holder may settle any such sales of Registrable Securities) if (i) Concho is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and Concho determines in good faith that Concho’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Registration Statement or (ii) Concho has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Concho, would materially adversely affect Concho; provided, however, in no event shall the Purchasers be suspended for a period that exceeds an aggregate of 60 days in any 180-day period or 120 days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, Concho shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement, shall promptly terminate any suspension of sales it has

Exhibit B-4

put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

(c) Additional Rights to Liquidated Damages. If (i) the Holders shall be prohibited from selling their Registrable Securities under the Registration Statement as a result of a suspension pursuant to Section 2.01(b) of this Agreement in excess of the periods permitted therein or (ii) the Registration Statement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded by a post-effective amendment to the Registration Statement, a supplement to the prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is lifted or a post-effective amendment, supplement or report is filed with the Commission, but not including any day on which a suspension is lifted or such amendment, supplement or report is filed and declared effective, if applicable, Concho shall owe the Holders an amount equal to the Liquidated Damages, following (x) the date on which the suspension period exceeded the permitted period under 2.01(b) of this Agreement or (y) the day after the Registration Statement ceased to be effective or failed to be useable for its intended purposes, as liquidated damages and not as a penalty. For purposes of this Section 2.01(c), a suspension shall be deemed lifted on the date that notice that the suspension has been lifted is delivered to the Holders pursuant to Section 3.01 of this Agreement.

Section 2.02 Piggyback Rights.

(a) Participation. If at any time Concho proposes to file (i) a prospectus supplement to an effective shelf registration statement, other than the Registration Statement contemplated by Section 2.01 of this Agreement, or (ii) a registration statement, other than a shelf registration statement, in either case, for the sale of Common Stock in an Underwritten Offering for its own account and/or another Person, then as soon as practicable but not less than three Business Days prior to the filing of (x) any preliminary prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b) under the Securities Act, (y) the prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b) under the Securities Act (if no preliminary prospectus supplement is used) or (z) such registration statement, as the case may be, then Concho shall give notice (including, but not limited to, notification by electronic mail) of such proposed Underwritten Offering to the Holders and such notice shall offer the Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing; provided, however, that if Concho has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have a material adverse effect on the price, timing or distribution of the Common Stock in the Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b) of this Agreement. The notice required to be provided in this Section 2.02(a) to Holders shall be provided on a Business Day pursuant to Section 3.01 hereof and receipt of such notice shall be confirmed by such Holder. Each such Holder shall then have three Business Days after receiving such notice to request inclusion of Registrable Securities in the Underwritten Offering, except that such Holder shall have one Business Day after such Holder confirms receipt of the notice to request inclusion of Registrable Securities in the Underwritten Offering in the case of a “bought deal” or “overnight

Exhibit B-5

transaction” where no preliminary prospectus is used. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, Concho shall determine for any reason not to undertake or to delay such Underwritten Offering, Concho may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such offering by giving written notice to Concho of such withdrawal up to and including the time of pricing of such offering. Each Holder’s rights under this Section 2.02(a) shall terminate when such Holder (together with any Affiliates of such Holder) holds less than $5 million of Purchased Common Stock, based on the Commitment Amounts. Notwithstanding the foregoing, any Holder may deliver written notice (an “Opt Out Notice”) to Concho requesting that such Holder not receive notice from Concho of any proposed Underwritten Offering.

(b) Priority of Rights. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of Common Stock included in an Underwritten Offering involving Included Registrable Securities advises Concho, or Concho reasonably determines, that the total amount of Common Stock that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have a material adverse effect on the price, timing or distribution of the Common Stock offered or the market for the Common Stock, then the Common Stock to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Concho, or Concho reasonably determines, can be sold without having such adverse effect, with such number to be allocated (i) first, to Concho, and (ii) second, pro rata among the Selling Holders party to this Agreement. The pro rata allocations for each such Selling Holder shall be the product of (a) the aggregate amount of Common Stock proposed to be sold by all Selling Holders in such Underwritten Offering multiplied by (b) the fraction derived by dividing (x) the amount of Common Stock owned on the Closing Date by such Selling Holder by (y) the aggregate amount of Common Stock owned on the Closing Date by all Selling Holders participating in the Underwritten Offering. All participating Selling Holders shall have the opportunity to share pro rata that portion of such priority allocable to any Selling Holder(s) not so participating. As of the date of execution of this Agreement, there are no other Persons with Registration Rights relating to Common Stock other than as described in this Section 2.02(b).

Section 2.03 Underwritten Offering.

(a) Request for Underwritten Offering. Any one or more Holders that collectively hold greater than $50 million of Registrable Securities, based on the purchase price per share of Common Stock under the Purchase Agreement, may deliver written notice to Concho that such Holders wish to dispose of an aggregate of at least $50 million of Registrable Securities, based on the purchase price per share of Common Stock under the Purchase

Exhibit B-6

Agreement, in an Underwritten Offering. Upon receipt of any such written request, Concho shall retain underwriters, effect such sale though an Underwritten Offering, including entering into an underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.08, and take all reasonable actions as are requested by the Managing Underwriter or Underwriters to expedite or facilitate the disposition of such Registrable Securities; provided, however, Concho management will not be required to participate in any roadshow or similar marketing effort on behalf of any such Holder.

(b) General Procedures. In connection with any Underwritten Offering under this Agreement, Concho shall be entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and Concho shall be obligated to enter into an underwriting agreement that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Concho to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Concho or the underwriters other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf, its intended method of distribution and any other representation required by Law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Concho and the Managing Underwriter; provided, however, that such withdrawal must be made up to and including the time of pricing of such Underwritten Offering. No such withdrawal or abandonment shall affect Concho’s obligation to pay Registration Expenses.

Section 2.04 Sale Procedures. In connection with its obligations under this Article II, Concho will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Registration Statement;

(b) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Registration Statement and the Managing Underwriter at any time shall notify Concho in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities,

Exhibit B-7

use its commercially reasonable efforts to include such information in such prospectus supplement;

(c) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or such other registration statement or supplement or amendment thereto, and (ii) such number of copies of the Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement;

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request; provided, however, that Concho will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(e) promptly notify each Selling Holder and each underwriter of Registrable Securities, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(f) immediately notify each Selling Holder and each underwriter of Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by this

Exhibit B-8

Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Concho of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Concho agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an 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 in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for Concho dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto, and a letter of like kind dated the date of the closing under the underwriting agreement, and (ii) a “cold comfort” letter, dated the date of the applicable registration statement or the date of any amendment or supplement thereto and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified Concho’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the “cold comfort” letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities and such other matters as such underwriters or Selling Holders may reasonably request;

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(j) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Concho personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, however, that Concho need not disclose any such information to any such representative unless and until such representative has entered into or is otherwise subject to a confidentiality agreement with Concho satisfactory to Concho (including any confidentiality agreement referenced in Section 8.06 of the Purchase Agreement);

(k) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Concho are then listed;

Exhibit B-9

(l) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Concho to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(m) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement; and

(n) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities.

(o) Concho agrees that, if any Purchaser could reasonably be deemed to be an “underwriter”, as defined in Section 2(a)(11) of the Securities Act, in connection with the registration statement in respect of any registration of Concho’s securities of any Purchaser pursuant to this Agreement, and any amendment or supplement thereof (any such registration statement or amendment or supplement a “Purchaser Underwriter Registration Statement”), then Concho will cooperate with such Purchaser in allowing such Purchaser to conduct customary “underwriter’s due diligence” with respect to Concho and satisfy its obligations in respect thereof. In addition, at any Purchaser’s request, Concho will furnish to such Purchaser, on the date of the effectiveness of any Purchaser Underwriter Registration Statement and thereafter from time to time on such dates as such Purchaser may reasonably request, (i) a letter, dated such date, from Concho’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to such Purchaser, and (ii) an opinion, dated as of such date, of counsel representing Concho for purposes of such Purchaser Underwriter Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, including a standard “10b-5” opinion for such offering, addressed to such Purchaser; provided, however, that with respect to any Placement Agent, Concho’s obligations with respect to this Section 2.04(o) shall be limited to one time, with an additional bring-down request within 30 days of the date of such documents. Concho will also permit legal counsel to such Purchaser to review and comment upon any such Purchaser Underwriter Registration Statement at least five Business Days prior to its filing with the Commission and all amendments and supplements to any such Purchaser Underwriter Registration Statement within a reasonable number of days prior to their filing with the Commission and not file any Purchaser Underwriter Registration Statement or amendment or supplement thereto in a form to which such Purchaser’s legal counsel reasonably objects.

Each Selling Holder, upon receipt of notice from Concho of the happening of any event of the kind described in Section 2.04(e) of this Agreement, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.04(e) of this Agreement or until it is advised in writing by Concho that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by Concho, such Selling Holder will, or will request the managing underwriter or underwriters, if any, to deliver to Concho (at Concho’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession,

Exhibit B-10

of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

If requested by a Purchaser, Concho shall: (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as such Purchaser reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or make amendments to any Registration Statement.

Section 2.05 Cooperation by Holders. Concho shall have no obligation to include in the Registration Statement Common Stock of a Holder, or in an Underwritten Offering pursuant to Section 2.02 of this Agreement Common Stock of a Selling Holder, who has failed to timely furnish such information that, in the opinion of counsel to Concho, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.06 Restrictions on Public Sale by Holders of Registrable Securities. For a period of 365 days from the Closing Date, each Holder of Registrable Securities who is included in the Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the 30-day period following completion of an Underwritten Offering of equity securities by Concho (except as provided in this Section 2.06); provided, however, that the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the officers or directors or any other Common Stockholder of Concho on whom a restriction is imposed in connection with such public offering. In addition, the provisions of this Section 2.06 shall not apply with respect to a Holder that (A) owns less than $5 million of Purchased Common Stock, based on the Commitment Amounts or (B) has submitted a notice requesting the inclusion of Registrable Securities in an Underwritten Offering pursuant to Section 2.02 or Section 2.03(a) hereof but is unable to do so as a result of the priority provisions contained in Section 2.02(b) hereof.

Section 2.07 Expenses.

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Concho’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on the Registration Statement pursuant to Section 2.01 hereof or an Underwritten Offering covered under this Agreement, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and The New York Stock Exchange fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the National Association of Securities Dealers, Inc., transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses and the fees and disbursements of counsel and independent public accountants for Concho, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance. “Selling Expenses” means

Exhibit B-11

all underwriting fees, discounts and selling commissions allocable to the sale of the Registrable Securities.

(b) Expenses. Concho will pay all reasonable Registration Expenses as determined in good faith, including, in the case of an Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. In addition, except as otherwise provided in Section 2.08 hereof, Concho shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.08 Indemnification.

(a) By Concho. In the event of an offering of any Registrable Securities under the Securities Act pursuant to this Agreement, Concho will indemnify and hold harmless each Selling Holder thereunder, its officers, members, managers, directors, employees, agents and other representatives, and each underwriter, pursuant to the applicable underwriting agreement with such underwriter, of Registrable Securities thereunder and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, and its officers, members, managers, directors, employees, agents and other representatives, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, officer, member, manager, director, employee, agent, other representative, underwriter or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors and officers, each such underwriter and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Concho will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in strict conformity with information furnished by such Selling Holder, its directors or officers or any underwriter or controlling Person in writing specifically for use in the Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such Selling Holder, its directors or officers or any underwriter or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Concho, its directors and officers, and each Person, if any, who controls Concho within the meaning of the Securities Act or of the Exchange Act, and its directors and officers, to the same extent as the foregoing indemnity from Concho to the

Exhibit B-12

Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration Statement or any preliminary prospectus or final prospectus included therein, or any amendment or supplement thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the net proceeds received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.08. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of net proceeds received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among

Exhibit B-13

other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.08 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.09 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Concho agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding Concho available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the Commission in a timely manner all reports and other documents required of Concho under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, furnish, unless otherwise not available at no charge by access electronically to the Commission’s XXXXX filing system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Concho, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Concho to register Registrable Securities granted to the Purchasers by Concho under this Article II may be transferred or assigned by any Purchaser to one or more transferee(s) or assignee(s) of such Registrable Securities; provided, however, that, (a) unless such transferee is an Affiliate of such Purchaser, each such transferee or assignee holds Registrable Securities representing at least $10 million of the Purchased Common Stock, based on the Commitment Amounts, (b) Concho is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee assumes in writing responsibility for its portion of the obligations of such Purchaser under this Agreement.

Exhibit B-14

Section 2.11 Limitation on Subsequent Registration Rights. From and after the date hereof, Concho shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities, (i) enter into any agreement with any current or future holder of any securities of Concho that would allow such current or future holder to require Concho to include securities in any registration statement filed by Concho on a basis that is superior to the piggyback rights granted to the Purchasers hereunder or (ii) grant registration rights to any other Person that would be superior to the Purchasers’ registration rights hereunder.

ARTICLE III
MISCELLANEOUS

Section 3.01 Communications. All notices and other communications provided for or permitted hereunder shall be made in writing by facsimile, electronic mail, courier service or personal delivery:

Section 3.02 Successor and Assigns This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including subsequent Holders of Registrable Securities to the extent permitted herein.

Section 3.03 Recapitalization, Exchanges, Etc. Affecting the Common Stock The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all stock of Concho or any successor or assign of Concho (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Registrable Securities, and shall be appropriately adjusted for combinations, stock splits, recapitalizations and the like occurring after the date of this Agreement.

Section 3.04 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The

Exhibit B-15

existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have.

Section 3.05 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 3.06 Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

Section 3.07 Governing Law. The Laws of the State of New York shall govern this Agreement without regard to principles of conflict of Laws.

Section 3.08 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or enforceability of such provision in any other jurisdiction.

Section 3.09 Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by Concho set forth herein. This Agreement, the Purchase Agreement and the Confidentiality Agreement pertaining to the sale of the Purchased Common Stock supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 3.10 Amendment. This Agreement may be amended only by means of a written amendment signed by Concho and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder.

Section 3.11 No Presumption. If any claim is made by a party relating to any conflict, omission or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

Section 3.12 Obligations Limited to Parties to Agreement. Each of the Parties hereto covenants, agrees and acknowledges that no Person other than the Purchasers (and their permitted assignees) and Concho shall have any obligation hereunder and that, notwithstanding that one or more of the Purchasers may be a corporation, partnership or limited liability company, no recourse under this Agreement or the Purchase Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of

PURCHASE AND SALE

Section 2.1 Purchase of Shares. On the terms and subject to the conditions contained herein, at the Closing, Sellers shall sell, assign and transfer to Purchaser and Purchaser shall purchase from Sellers, free and clear of all Claims, all of the Shares in exchange for the payment by Purchaser of the Purchase Price to the Sellers.

Section 2.2 Purchase Price. The purchase price for the Shares shall be $565,000,000.00 less the Cash Bonus Adjustment plus the Purchase Price Adjustment, if any (the “Purchase Price”), payable on

the Closing Date in cash to the Sellers in accordance with the wire transfer instructions to an account or accounts designated by the Sellers, in writing, not less than three business days prior to the Closing. At the Closing, each Seller shall be entitled to receive an amount equal to such Seller’s Ownership Percentage multiplied by the Purchase Price. Payment of the Purchase Price to the Sellers in accordance with this Section 2.2 shall represent full and final payment to the Sellers for the sale, assignment and transfer of the Shares, and each Seller acknowledges and agrees that such Seller shall not be entitled to receive any consideration for the sale, transfer and assignment of such Seller’s Shares other than the amount equal to such Seller’s Ownership Percentage multiplied by the Purchase Price. Schedule 2.2 represents the Purchase Price without any Purchase Price Adjustment.

Section 2.3 Bonus Payments.

(a) Immediately prior to Closing, Xxxxx Petroleum will approve payment of (i) a cash bonus to certain employees of Xxxxx Petroleum in accordance with existing bonus commitments to such employees as set forth under the heading “Prior Bonus” on the Compensation Letter (the “Prior Bonus”); (ii) cash bonuses, pursuant to an Employee Letter Agreement, to employees of Xxxxx Petroleum identified on the Compensation Letter, subject to such employees executing and delivering to Xxxxx Petroleum prior to Closing an Employee Letter Agreement and such employees continuing their employment with Xxxxx Petroleum or Purchaser (or any Affiliate of Purchaser) after the Closing Date (the “Retained Employees”), the amount payable to each Retained Employee being set forth in the Compensation Letter under the heading “Cash Bonus” (the “Cash Bonus”) and (iii) payment to certain independent contractors of Xxxxx Petroleum identified in the Compensation Letter, subject to such independent contractors executing and delivering to Xxxxx Petroleum prior to Closing a release in a form reasonably acceptable to Purchaser, the amount payable to each such independent contractor who executes a release being set forth in the Compensation Letter under the heading “Contractor Bonus” (the “Contractor Bonus”). Payment by Xxxxx Petroleum of the Prior Bonus and the Cash Bonus shall all be subject to applicable withholding Taxes.

(b) Notwithstanding anything to the contrary contained in this Agreement, the Purchase Price shall be reduced by the Cash Bonus Adjustment, which is calculated as follows: the product of (i) the sum of the Prior Bonus plus the Cash Bonus plus the Contractor Bonus and (ii) 65%. With respect to any employee of Xxxxx Petroleum identified in the Compensation Letter who is intended to receive a Cash Bonus and who does not execute and deliver to Xxxxx Petroleum the Employee Letter Agreement prior to Closing and any independent contractor of Xxxxx Petroleum identified in the Compensation Letter who does not execute and deliver to Xxxxx Petroleum the release contemplated in Section 2.3(a) prior to Closing, such employee or independent contractor shall not be entitled to receive the Cash Bonus or the Contractor Bonus, as the case may be, and an amount equal to the product of (A) the amount of any such Cash Bonus and Contractor Bonus not paid pursuant to the foregoing and (B) 65%, shall be paid to Sellers at Closing as an adjustment to the Purchase Price (such amount being referred to as the “Purchase Price Adjustment”).

(c) The Prior Bonus shall be paid by Xxxxx Petroleum immediately prior to the Closing to the employees and in the amounts set forth in the Compensation Letter, provided that such individuals are employed by Xxxxx Petroleum at the time of such payment. The Contractor Bonus shall be paid by Xxxxx Petroleum immediately prior to Closing to the independent contractors who execute and deliver a release in accordance with Section 2.3(a) in the amounts set forth in the Compensation Letter, provided that such independent contractors are then engaged by Xxxxx Petroleum at the time of such payment. The Cash Bonus will be paid by Xxxxx Petroleum to each Retained Employee in installments pursuant to an Employee Letter Agreement

executed by the Retained Employee that will be delivered to Xxxxx Petroleum prior to Closing as follows: (1) 50% to be paid by Xxxxx Petroleum immediately prior to Closing, provided that such individuals are employed by Xxxxx Petroleum at the time of such payment (the “First Bonus Installment”); (2) 25% to be paid by Xxxxx Petroleum (or Concho or its Affiliates) on the first anniversary of the Closing Date, assuming satisfaction of the terms of the Employee Letter Agreement; and (3) 25% to be paid by Xxxxx Petroleum (or Concho or its Affiliates) on the second anniversary of the Closing Date, assuming satisfaction of the terms of the Employee Letter Agreement. Under the terms of each Employee Letter Agreement, each Retained Employee will agree to forfeit any unpaid portion of the Cash Bonus in the event that such Retained Employee’s employment with Xxxxx Petroleum (or its successor) or Purchaser (or any Affiliate of Purchaser) is terminated for cause (as defined in the Employee Letter Agreement) or such Retained Employee terminates his own employment for any reason. In addition, under the terms of each Employee Letter Agreement, each Retained Employee will be entitled to receive the full amount of the unpaid Cash Bonus allocated to such Retained Employee in the event of the death or disability (as such term is defined in the Employee Letter Agreement) of such Retained Employee or change in control of Purchaser (as such term is defined in the Employee Letter Agreement) or in the event that such Retained Employee’s employment with Xxxxx Petroleum (or its successor) or Purchaser (or any Affiliate of Purchaser) is terminated by Xxxxx Petroleum (or its successor) or Purchaser (or any Affiliate of Purchaser) for any reason other than for cause (as defined in the Employee Letter Agreement); provided, however, that with respect to any portion of the Cash Bonus payable to a Retained Employee in connection with any such termination of employment, the payment of such amount shall be deferred to the extent required to satisfy the requirements of Section 409A(a)(2)(B)(i) of the Code. Within ten business days following the second anniversary of the Closing Date, Purchaser shall pay to the Sellers an amount (the “Cash Bonus Return”) equal to the product of (i) any unpaid portion of the Cash Bonus as a result of any forfeitures in accordance with the terms of the Employee Letter Agreement and (ii) 65%; provided, however, that Purchaser shall not be obligated to include in such calculation any unpaid portion of the Cash Bonus with respect to a Retained Employee who was employed by any Seller or any Affiliate of any Seller after the Closing Date in violation of Section 4.12(b). Each Seller shall be entitled to receive an amount equal to such Seller’s Ownership Percentage multiplied by the Cash Bonus Return. For federal income tax purposes, the parties shall treat the Cash Bonus Return as an adjustment to the Purchase Price.

(d) The Prior Bonus, the First Bonus Installment and the Contractor Bonus will be paid by the distribution and delivery of checks payable to the Retained Employees and drawn on accounts of Xxxxx Petroleum. To the extent necessary, Purchaser shall advance sufficient funds by wire transfer to enable Xxxxx Petroleum to timely pay the Prior Bonus, the First Bonus Installment and the Contractor Bonus and related employment Taxes.

(e) For all applicable Tax purposes, the parties agree to treat (i) the Prior Bonus, the First Bonus Installment and the Contractor Bonus as compensation paid by Xxxxx Petroleum for the Tax Period that includes the Closing Date, and (ii) any subsequent payments of installments of the Cash Bonus as employee compensation paid by Xxxxx Petroleum or any successor thereto in future Tax Periods. The parties shall report and file all Tax Returns consistent with this position and shall take no applicable Tax position contrary thereto or inconsistent therewith prior to a final determination in court or by agreement with an applicable Governmental Authority after consultation with the other parties.

Section 2.4 Title Deficiency . Purchaser may make or cause to be made at its expense such examination as it may desire of the title of a Company to the Properties. For such purposes, Sellers shall or shall cause the Companies to (a) give to Purchaser and its representatives full access, subject to consent

under applicable Contracts, at any reasonable time to all of the files, records, contracts, correspondence, computer output and data files, maps, data, reports, plats, abstracts of title, lease files, well files, unit files, division order files, production marketing files, title opinions, title files and title records, title insurance policies, ownership maps, surveys, and any other information, data, records, and files of each Company (or to which any Company has access) relating in any way to the title to the Properties, the past or present operation thereof, and the marketing of production therefrom; (b) furnish to Purchaser all other information in the possession of, or available to, any Company with respect to the title to the Properties as Purchaser may from time to time reasonably request; and (c) authorize Purchaser and its representatives to consult with attorneys, abstract companies, and representatives of the Companies, whether utilized in the past or presently, concerning title-related matters with respect to the Properties. A “Title Deficiency” shall exist if (i) the Companies are obligated to bear and pay costs and expenses associated with the exploration, maintenance, development and operation of any Property through the plugging, abandonment, and salvage of such Property greater than the working interest for such Property represented in the Property Letter without a corresponding increase in the applicable net revenue interest in such Property represented in the Property Letter, (ii) the Companies are entitled to receive and retain a share of the Hydrocarbons produced, saved, and marketed from any Property without suspension, reduction or termination through the plugging, abandonment, and salvage of such Property less than the net revenue interest for that Property represented in the Property Letter, (iii) any Property is subject to a Claim (other than a Permitted Encumbrance), (iv) any Property is subject to a preferential purchase right, right of first offer, right of first refusal or consent, the absence of which would render the Transactions void or voidable or subject any Company to potential loss of any Property or any interest therein or to damages or penalties upon the occurrence of a change of control of the Person holding the interest in such Property or any similar purchase or consent right, in each case that would be triggered or would otherwise arise as a result of the consummation of the sale and delivery of the Shares by Sellers to Purchaser pursuant to this Agreement, or (v) any combination of the foregoing exist. Purchase shall have the right to notify Sellers in writing of any Title Deficiencies (a “Title Deficiency Notice”) no later than 5:00 p.m. (Central time) on the fourth business day prior to the Closing Date. Any Title Deficiency Notice shall include Purchaser’s good faith determination based on customary industry standards of the dollar value of such Title Deficiency, which value shall be determined based upon the relative change in the Maximum Title Deficiency Amount of such Property (each, a “Title Deficiency Amount”). By way of illustration: (i) if a Company’s actual net revenue interest in a Property is less than the net revenue interest set forth for such Property in the Property Letter or if a Company’s actual working interest in a Property is greater than the working interest set forth in the Property Letter (without a corresponding increase in a Company’s net revenue interest), then value of the Title Deficiency would be that portion of the Maximum Title Deficiency Amount represented by the relative difference between the actual net revenue interest or working interest in the property and the net revenue interest or working interest for such Property in the Property Letter; or (ii) if a Title Deficiency is a lien, then the value of the Title Deficiency would be the cost of removing the lien. Furthermore, in the event of any Title Deficiency described in clause (iv) above, the value of any such Title Deficiency shall be the Maximum Title Deficiency Amount of the Property subject to such purchase or consent right. Any reduction in the value of any Property due to a Title Deficiency shall be included in the calculation for determining whether the Purchaser may terminate this Agreement pursuant to Section 2.6. No adjustment to the Purchase Price will be made for any Title Deficiency. Purchaser agrees to notify the Agent as soon as reasonably practicable following its determination of a Title Deficiency in order to provide Sellers the reasonable opportunity to provide Purchaser with additional records or additional information that could resolve or reduce the value of such Title Deficiency. Purchaser acknowledges that certain Properties are subject to certain liens for the benefit of X.X.Xxxxxx Chase Bank and Xxxxx Fargo Bank, which liens shall not be considered Title Deficiencies so long as such liens are released as of the Closing.

Section 2.5 Property Condition Deficiency. Commencing upon execution of this Agreement and ending at 5:00 p.m. (Central Time) on the fourth business day prior to the Closing Date, Purchaser

shall be entitled to inspect, review and evaluate all records, facilities, and Properties of each Company, interview Company personnel, and perform such environmental sampling and testing as may be appropriate to enable the Purchaser to assess the environmental and physical condition of the Properties and the environmental liabilities of each Company. The purpose of the inspection of the physical condition of the Properties shall be to confirm that they are maintained in accordance with the legal and contractual obligations of the Companies. Purchaser shall use reasonable care not to damage the Properties during the course of its inspections pursuant to this Section 2.5. Based on its review and inspection, Purchaser shall in good faith determine whether the value of a Property could reasonably be expected to be impaired because (i) of property condition issues (including any pollution, contamination, remedial obligation, or liability under any Environmental Law), (ii) any Property or Company is in violation of any Environmental Law, (iii) of any written notice or record from a Governmental Authority or other Person of a violation of Environmental Laws or a Contract with regard to any property condition the Companies are contractually or legally obligated to remedy, or (iv) any combination of the foregoing (any, a “Property Condition Deficiency”). The Purchaser shall determine in good faith based on customary industry standards the dollar amount that a Property could reasonably be expected to be impaired based on the amount reasonably necessary to remedy any violation(s) of Environmental Law, to bring the Property into compliance with applicable Environmental Laws or to restore a Property to its contractually required condition (each, a “Property Condition Deficiency Amount”). The Purchaser shall determine the total dollar value reduction of all Property Condition Deficiencies. The dollar value of any impairment of any Property due to a Property Condition Deficiency shall be included in the calculation for determining whether the Purchaser may terminate this Agreement pursuant to Section 2.6. No adjustment to the Purchase Price will be made for any Property Condition Deficiency.

Section 2.6 Termination Due to Deficiencies. If the aggregate Title Deficiency Amounts plus the aggregate Property Condition Deficiency Amounts, as determined in Sections 2.4 and 2.5 above, exceed $16,950,000.00, then Purchaser, at its election, may give written notice to Sellers not later than 5:00 p.m. (Central Time) on the fourth business day prior to the Closing Date (the “Deficiency Notice”).

(a) The Deficiency Notice provided hereunder, if given, shall include (i) a description of each Title Deficiency or Property Condition Deficiency, (ii) the basis for each Title Deficiency or Property Condition Deficiency, (iii) each Property or the portion thereof affected by the Title Deficiency or Property Condition Deficiency, (iv) each Title Deficiency Amount or Property Condition Deficiency Amount and (v) with respect to each Title Deficiency Amount, the applicable Company owning the Property subject to such Title Deficiency Amount.

(b) Sellers may accept Purchaser’s Deficiency Notice or object thereto. If the Sellers object to certain Property Condition Deficiency Amounts set forth in the Deficiency Notice that, if reduced, could reasonably be expected to reduce the aggregate Title Deficiency Amounts and Property Condition Deficiency Amounts below $16,950,000.00, the Sellers shall deliver a written notice of such objection (the “Dispute Notice”) to Purchaser no later than 5:00 p.m. on the third business day after the date of the Deficiency Notice. If the Dispute Notice is not delivered by 5:00 p.m. on the third business day after the date of the Deficiency Notice, Purchaser may terminate this Agreement pursuant to Section 6.1(g). Upon delivery of a Dispute Notice to Purchaser, the Termination Date and the Closing Date shall automatically be extended from July 31, 2008 to August 31, 2008. Within seven (7) business days after the date of the Dispute Notice, Sellers shall deliver a more detailed written notice (the “Dispute Explanation”), which shall specifically identify all disputed Property Condition Deficiency Amounts (each, a “Disputed Item”) and shall include the Sellers’ good faith estimate of the value of each Disputed Item (each, a “Sellers’ Estimate”); provided, however, that no Disputed Item shall be permitted to be included in the Dispute Explanation if the Sellers’ Estimate of such Disputed Item would be greater than 90% of such Property Condition Deficiency Amount.

(c) After delivery of the Dispute Explanation, the parties shall promptly refer the Disputed Items to a person selected by mutual agreement of the parties who possesses the requisite knowledge, skill and experience to determine the issue (the “Defect Expert”). The Defect Expert may enlist the advice of any environmental consultant mutually agreed upon by the parties.

(d) Upon referral of the Disputed Items to the Defect Expert, the Purchaser and the Sellers will be afforded an opportunity to present to the Defect Expert any materials relating to the validity of, or their valuation of, the Disputed Items and to discuss the determination, prior to any final determination, of the Disputed Items with the Defect Expert. The Defect Expert shall be required to adopt a value (the “Determined Amount”) that is equal to either the Property Condition Deficiency Amount or the Sellers’ Estimate for each Disputed Item, and such decision, made in writing and signed by the Defect Expert, shall determine such dispute.

(e) If, after determination of the Determined Amount for each Disputed Item by the Defect Expert, the sum of (i) all Title Deficiency Amounts, (ii) all Property Condition Deficiency Amounts for Property Condition Deficiencies not included in the Dispute Explanation and (iii) all Determined Amounts (such sum, the “Adjusted Defect Amount”) exceeds $16,950,000.00, then Sellers shall bear all expenses of the Defect Expert and any other expert retained by the Defect Expert. If the Adjusted Defect Amount is less than or equal to $16,950,000.00, then Purchaser shall bear all expenses of the Defect Expert and any other expert retained by the Defect Expert.

(f) In the event that Purchaser does not deliver a timely Deficiency Notice pursuant to this Section 2.6 or the aggregate of the Title Deficiency Amounts and the Property Condition Deficiency Amounts is ultimately determined to be less than $16,950,000.00, then Purchaser shall not be permitted to terminate this Agreement pursuant to Section 6.1(g). In the event that Purchaser does deliver a timely Deficiency Notice pursuant to this Section 2.6 and either Sellers do not deliver a timely Dispute Notice or Sellers do deliver a timely Dispute Notice but the aggregate of the Title Deficiency Amounts and the Property Condition Deficiency Amounts is ultimately determined to be equal to or greater than $16,950,000.00, then Purchaser may terminate this Agreement pursuant to Section 6.1(g). After Purchaser completes its due diligence under Sections 2.4 and 2.5, if Purchaser proceeds to the Closing, Purchaser shall be deemed to have accepted the Properties and shall have no claim for indemnification from the Sellers for defects, damages, costs or other liabilities for items that would have been a Title Deficiency or a Property Condition Deficiency.

Section 2.7 Along-side Interests. Within five (5) business days of the execution of this Agreement, Purchaser will offer to purchase the rights and interests in the Properties (“Along-side Interests”) owned by the Persons listed on Schedule 2.7 for the prices shown on such Schedule pursuant to the form of purchase agreement attached hereto as Exhibit B. None of the Persons listed on Schedule 2.7 will be obligated to sell their Along-side Interests. Purchaser or its Affiliate and those Persons who accept Purchaser’s offer shall promptly sign binding agreements for the purchase and sale of the Along-side Interests. If Purchaser’s offer is accepted by a Designated Seller, Purchaser must close the purchase of the Along-side Interest simultaneously with the Closing, with payment of the purchase price for the Along-side Interest paid in cash by wire transfer to such Designated Seller as directed by such Designated Seller. If the owner of the Along-side Interest is a Person other than a Designated Seller, Purchaser must close the purchase of the Along-side Interests of such Person who accepts the Purchaser’s offer no later than 90 days after Closing, by payment of the purchase price pursuant to the purchase agreement for the Along-side Interests purchased in cash by wire transfer to the account designated by the respective seller.

Section 2.8 Distribution of Excluded Companies. At or prior to Closing, Holding and Energy intend to make a direct or indirect distribution of the Excluded Companies to the Sellers containing certain properties which are either presently owned by the Excluded Companies or which will be contributed to the Excluded Companies immediately before the distribution of the Excluded Companies. Schedule 2.8(a) lists the properties and assets that will be owned by Xxxxx Resources LLC with their respective values immediately prior to the distribution of Xxxxx Resources LLC by Holding (“Xxxxx Holding Distribution”). Schedule 2.8(b) lists the properties and assets that will be owned by Xxxxx Equity LLC immediately prior to the distribution of Xxxxx Equity LLC by Energy (the “Xxxxx Energy Distribution”) with their respective values. The Sellers shall consult with Purchaser as to the structure, method and status of the Xxxxx Holding Distribution and the Xxxxx Energy Distribution and related matters. The parties shall report and file all Tax Returns consistent with such values.

Section 2.9 Agreed Net Working Capital Distribution. At or prior to the Closing, Holding and Energy intend to make a distribution of the amount of agreed net working capital on hand as of April 30, 2008 (“Agreed Net Working Capital Distribution”). The parties agree that the amount of the Agreed Net Working Capital Distribution is $34,096,384.00. The distribution of the Agreed Net Working Capital Distribution shall not affect the Purchase Price. The Agreed Net Working Capital Distribution may occur anytime before or at Closing.

Section 2.10 Withholding. In the event Purchaser shall determine that it is required to deduct and withhold from the consideration otherwise payable pursuant to this Agreement any amounts under any provision of federal, state, local or foreign Tax law, it shall notify the Person who otherwise would be entitled to such consideration and give such Person an opportunity to demonstrate why such withholding is not required; provided that Purchaser, after consulting with Tax counsel to it, shall make the final determination of any requirement to withhold. If Purchaser or any Affiliate or agent thereof, as the case may be, so withholds amounts pursuant to this Section 2.10, such amounts shall be promptly remitted to the appropriate Governmental Authority as required by applicable law, and shall be treated for all purposes of this Agreement as having been paid to Sellers in respect of which such deduction or withholding was made.

Purchaser shall reimburse Sellers and/or the Companies for all costs incurred by any of them in assisting Purchaser, its representatives and Purchaser’s Auditor.

Section 4.5 Consent from Third Parties. Each Seller and each Company will use their respective commercially reasonable efforts to acquire the written consent from all third parties to Contracts with respect to which the consummation of the Transactions or the compliance with this Agreement, could reasonably be expected to result in, or cause a default, or constitute an event of default (or an event which the giving of notice or the passage of time could cause a default or event of default), or otherwise cause any Company to be in breach of, or unable to perform under, such Contracts, or grant any other party thereto the right to modify or terminate such Contract or the performance of any Company thereunder. Each Seller and each Company shall use commercially reasonable efforts to obtain the consent from all relevant Persons to allow the Purchaser and its representatives to review all Contracts with respect to which the consummation of the Transactions or the compliance with this Agreement, could reasonably be expected to result in, or cause a default, or constitute an event of default (or an event which the giving of notice or the passage of time could cause a default or event of default), or otherwise cause such Company to be in breach of, or unable to perform under, such Contracts, or grant any other party thereto the right to modify or terminate such Contract, or alter the conduct of business thereunder by the parties prior to the date of this Agreement. Each Seller and Company shall cooperate with the Purchaser, and vice versa, in the execution and filing of all notices, forms and agreements as may be

necessary to obtain any consent or approvals of any Governmental Authority that may be necessary or appropriate to effectuate the Transactions, including any consents or approvals relating to any permits, licenses or registrations held by the Companies or required for the operation of the Properties. Purchaser agrees to use commercially reasonable efforts to assist Sellers to obtain any such consents to the extent reasonably requested by Sellers or Companies.

Section 4.6 Further Assurances. Subject to the terms and conditions of this Agreement, each of the parties hereto will use all commercially reasonable efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things reasonably necessary, proper or advisable, under applicable laws and regulations to fulfill its obligations under this Agreement and to consummate and make effective the transactions.

Section 4.7 Public Announcements. Prior to Closing, Sellers and Purchaser will consult with each other before issuing any press release or otherwise making any written statements with respect to this Agreement and the Transactions, and neither Sellers, the Companies nor Purchaser shall issue any such press release or make any such written public statement without the prior consent of the other parties, which consent shall not be unreasonably withheld; provided, however, that Purchaser may make any public disclosure required by applicable law or stock exchange rule (in which case Purchaser shall use reasonable efforts to advise Sellers and give Sellers an opportunity to comment on the proposed disclosure prior to making the disclosure).

Section 4.8 Resignations; Releases. Each of the Persons identified as officers of the Companies on Schedule 4.8 shall tender to Xxxxx Petroleum prior to the Closing Date written resignations from such positions and their employment with the Companies as of the Closing Date, together with a release of all claims against the Companies and the Purchaser in a form reasonably satisfactory to Purchaser. In addition, the Sellers and the Companies shall use reasonable best efforts to obtain from the Persons identified as employees of the Companies on Schedule 4.8 prior to the Closing Date written resignations of their employment with the Companies as of the Closing Date, together with a release of all claims against the Companies and the Purchaser in a form reasonably satisfactory to Purchaser. Sellers acknowledge that certain of their Affiliates intend to employ the Persons identified on Schedule 4.8 and, in connection with their employment by one or more of such Affiliates, to offer such Persons a bonus arrangement substantially similar to the Cash Bonus described in Section 2.3. In the event that a Person identified on Schedule 4.8 refuses to execute and deliver to Xxxxx Petroleum the release contemplated by this Section 4.8, Sellers agree not to offer such bonus arrangement to such Persons. Sellers and the Companies also agree to use reasonable best efforts to obtain (i) from each of the employees who is intended to receive a Cash Bonus, an executed and delivered Employee Letter Agreement prior to the Closing Date and (ii) from each of the independent contractors identified in the Compensation Letter, an executed and delivered release contemplated by Section 2.3 prior to the Closing Date. It is the intention of the parties that the resignation of the employees pursuant to Section 4.8 will not adversely affect such employees with regard to obtaining the benefits of vesting in Plans (including permitted actions under Section 4.1(b)) that would have occurred if such employees had remained employed by the Companies immediately after Closing, and the parties agree to take such actions as are reasonably necessary to cause such vesting to occur.

Section 4.9 Name Change. Purchaser agrees to transfer and assign or permit Xxxxx Petroleum to transfer and assign the Xxxxx Petroleum logo trademark to Sellers at Closing, including all registrations listed on Schedule 4.9. Sellers agree to grant a limited license to use the Xxxxx logo and trademark to Purchaser until December 1, 2008; provided, however, that such limited license shall continue beyond December 1, 2008 solely to allow Purchaser to use the Xxxxx logo and trademark on all signs in existence in field operations at the time of Closing until March 31, 2009, by which time Purchaser shall have replaced all signs that use the “Xxxxx” name. Purchaser agrees to transfer all

operations and permits in the Companies to Purchaser’s name no later than December 1, 2008. Purchaser agrees to change the legal name of Xxxxx Petroleum LP by December 31, 2008 to another name not including the name “Xxxxx” and to coordinate that name change with Sellers so that they may file a Certificate of Formation for an entity using that name. By March 31, 2009, Purchaser will stop all use of the “Xxxxx” name in any public form or fashion other than in the context of reporting Purchaser’s historical results of operations or otherwise describing this Transaction. All other Companies names will be changed to entity names that do not include the “Xxxxx” name no later than March 31, 2009.

Section 4.10 Employment Matters. Purchaser agrees that, for a period of two years following the Closing Date, it or one of its Affiliates (including the Companies) will offer to continue the employment of each Retained Employee in the same city of their employment as of immediately prior to the date of this Agreement at a position performing generally similar work activities and job function. The parties acknowledge that the overall job responsibilities of a Retained Employee may be adjusted from time to time during such two year period based upon the organizational and operating structure of Purchaser and its Affiliates and based upon the overall job performance and capabilities of the Retained Employee. Notwithstanding the foregoing, Purchaser or one of its Affiliates shall have the right during such two-year period to terminate the employment of any Retained Employee. In the event that Purchaser or one of its Affiliates terminates the employment of a Retained Employee during the two-year period following the Closing Date for any reason other than for cause (as such term is defined in the Employee Letter Agreement), Purchaser agrees (i) to pay to such terminated Retained Employee, in a lump-sum payment (less applicable withholding taxes and subject to any deferral of the time of payment necessary to satisfy the requirements of Section 409(a)(2)(B)(i) of the Code), (A) the amount of the base salary or wages, if any, that would have otherwise been owed to such Retained Employee from the date of termination of employment until the second anniversary of the Closing Date and (B) any portion of the Cash Bonus that has not yet been paid and (ii) to provide, from the date of termination until the second anniversary of the Closing Date, such terminated Retained Employee with medical benefits consistent with those provided to similarly situated employees of Purchaser and its Affiliates who have not terminated employment. In the event that the employment of a Retained Employee is terminated due to death or disability (as such term is defined in the Employee Letter Agreement), Purchaser agrees to pay to such Retained Employee, in a lump-sum payment (less applicable withholding taxes and subject to any deferral of the time of payment necessary to satisfy the requirements of Section 409(a)(2)(B)(i) of the Code) any portion of the Cash Bonus that has not yet been paid. Each Retained Employee shall be provided with substantially similar benefits afforded to similarly situated employees of Purchaser and its Affiliates; provided, however, that in no event shall the base salary or base wage, as applicable, of a Retained Employee be less than the base salary or base wage, as applicable, of such Retained Employee in effect immediately prior to the date of this Agreement, except to the extent of any salary reduction generally applicable to all employees of Purchaser. Accrued and unused vacation and sick leave of each Retained Employee shall be honored by Purchaser and all seniority and vesting earned by such Retained Employee prior to the Closing Date and recognized by the Companies shall be credited by Purchaser to the extent applicable under Purchaser’s employee benefit plans for eligibility and vesting purposes and for benefit determination purposes under any applicable vacation, sick leave, or severance benefit program, and Purchaser shall approve any amendments necessary of Purchaser’s employee benefit plans to give effect to the foregoing.

Section 4.11 Parachute Payments. The parties to this Agreement acknowledge that a portion of the payments and benefits to be provided to certain employees and directors of the Companies in connection with the Transactions may constitute “parachute payments” under Section 280G of the Code unless shareholder approval of such payments is obtained in a manner that satisfies the requirements of Section 280G(b)(5) of the Code. Notwithstanding anything to the contrary in this Agreement, subject to the prior review and approval of Purchaser, Sellers shall cause the Companies to seek such shareholder approval in such manner and the Companies may take any and all actions reasonably necessary to secure

such approval. At least five days prior to the Closing Date, Sellers shall provide to Purchaser an original, fully executed copy of all shareholder consents obtained pursuant to the provisions of this Section 4.11.

Section 4.12 Non-Competition; Non-Solicitation. Each Seller expressly covenants and agrees that:

(a) for a period of two years from and after the Closing Date, each Seller will not, and will cause its Affiliates not to, directly or indirectly, solicit, own, or participate in any of the Properties, but this restriction does not prohibit a Seller from acquiring oil, gas and/or mineral leases, oil and gas leases, contracts, agreements and/or other interests to explore for and/or develop Hydrocarbons in lands where Purchaser has allowed Leases covering those lands or interests in lands or Properties to expire according to their terms for any reason; and

(b) for a period of two years from and after the date of this Agreement, each Seller will not, and will cause its Affiliates not to, directly or indirectly, solicit or contact with a view to the engagement or employment of any Retained Employee, but this restriction specifically does not include (i) a prohibition on a Seller hiring a Retained Employee who independently responds to a general advertisement for employment without the Seller having directly or indirectly solicited this response, (ii) a prohibition on a Seller directly soliciting or hiring the Retained Employee who has a brother who is expected to be employed by Seller or one of its Affiliates immediately after the Closing, or (iii) a prohibition on a Seller from soliciting or hiring a Retained Employee who at the time he is solicited and hired by Seller is employed by a Person other than Purchaser or its Affiliates.

(c) Other than the specific restrictions contained in clauses (a) and (b) above, each Seller shall have no other express or implied limitations as to competition with the Purchaser from and after the date of this Agreement.

(d) In the event any Seller breaches Section 4.12(a) of this Agreement, Purchaser shall have the right, which right shall be exercisable for a period of 30 months from and after the Closing Date, to cause Seller or its Affiliate to sell, transfer and assign to Purchaser the interest in the Property that was acquired by Seller or its Affiliate in violation of Section 4.12(a) at a price equal to (i) the price paid by such Seller or its Affiliate for such interest in the Property, (ii) plus, any capital expenditures made by such Seller or its Affiliate with respect to such interest in such Property, and (iii) minus, any revenues (net of normal operating expenses) received by such Seller or its Affiliate from such interest in such Property.

Section 4.13 Tax Matters.

(a) Other than the 2008 Short Period Consolidated Tax Returns, Sellers shall prepare or cause to be prepared any and all Tax Returns for a member or members of the Company Group covering a Tax period ending on or before the Closing Date. Not later than 30 days prior to the due date (including extensions) or proposed date of filing (if earlier) of each such Tax Return, Sellers shall deliver a copy of such Tax Return to Purchaser for its review and comment. Sellers shall make any changes to each such Tax Return reasonably requested by Purchaser, with any disputes resolved by a mutually acceptable, nationally recognized, independent accounting firm, and shall deliver a final draft of such Tax Return to Purchaser prior to the due date for filing such Tax Return. To the extent any member of the Company Group is required to execute and/or file any such Tax Return after the Closing Date, Purchaser shall cause such Tax Return (reflecting all agreed or finally determined changes) to be filed upon receipt thereof. All such Tax Returns shall

be prepared on a basis consistent with past practice except to the extent otherwise required by applicable law.

(b) Purchaser shall prepare the 2008 Short Period Consolidated Tax Returns and any Tax Returns due for or with respect to a member or members of the Company Group for a Tax period that includes but does not end on the Closing Date. Not later than 30 days prior to the due date (including extensions) or proposed date of filing (if earlier) of each such Tax Return, Purchaser shall deliver a copy of such Tax Return to Sellers for its review and comment. Purchaser shall make any changes to each such Tax Return reasonably requested by Sellers to the extent such changes would affect the amount of Taxes for which Sellers are responsible pursuant to Section 4.13(c), with any disputes resolved by a mutually acceptable, nationally recognized, independent accounting firm, and shall deliver a final draft of such Tax Return to Sellers prior to the due date for filing such Tax Return. All such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable law.

(c) With respect to any Taxes due from Purchaser or its Affiliates (including a member or members of the Company Group after the Closing Date) (i) for a Tax period ending on or before December 31, 2007 (including for this purpose any such period for which the income, receipts or other base of Tax is measured even if the right to do business for a different period is secured by reason of such payment of Taxes), or (ii) as a result of (A) the transactions contemplated by Section 2.8 (to the extent the amount of such Taxes exceeds 36% of the value of the properties and assets set forth on Schedule 2.8(a)), (B) the transactions contemplated by Section 2.9, (C) any breach of the representations or obligations set forth in Section 3.1(m), (D) any breach of the representations or obligations set forth in Section 4.1 (including, solely for this purpose, Taxes resulting from transactions occurring at any time from January 1, 2008 through the Closing Date that would be in breach of such covenant but for the fact they occur prior to the date hereof) or (E) any breach of the representations or obligations set forth in Section 4.11, Sellers shall pay the amount of such Taxes (as set forth on the applicable agreed or finally determined Tax Returns relating thereto or as otherwise agreed by the parties or finally determined by a mutually acceptable, nationally recognized, independent accounting firm) to Purchaser on or before 10 days prior to the due date therefor, and shall otherwise agree promptly to reimburse Purchaser and its Affiliates for their costs to the extent they are later obligated to pay such Taxes.

(d) In the event the 2008 Short Period Consolidated Tax Return reflects a net operating loss for U.S. federal income tax purposes, the parties acknowledge and agree that Purchaser shall be entitled to prepare and cause to be filed an amended return for the Holding Consolidated Group for a prior year or years claiming a refund of Taxes resulting from the carryback of such net operating loss and, as between Purchaser and Sellers, Purchaser shall be entitled to receive and retain any refund or other Tax benefit obtained as a result of such carryback notwithstanding any subsequent adjustments pursuant to any audit of the Tax Returns for such prior years. Purchaser shall not and shall cause its Affiliates not to (in each case without the prior consent of Sellers and except as required by applicable Law) amend any Tax Return, or waive or extend any statute of limitations for a Tax period ending on or before or including the Closing Date, if such amendment, waiver, or extension would increase the amount of Taxes payable by any Seller or any member or members of the Company Group for which Sellers are obligated to reimburse Purchaser hereunder.

(e) Sellers and Purchaser shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns, any audit, litigation or other proceeding with respect to Taxes and Tax Returns. Such cooperation shall include the

retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit or proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder; provided, however, the party requesting assistance shall pay the reasonable out-of-pocket expenses incurred by the party providing such assistance; provided, further, no party shall be required to provide assistance at times or in amounts that would interfere unreasonably with the business and operations of such party. Sellers and Purchaser further agree, 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 any member of the Company Group (including with respect to the Transactions). Sellers and Purchaser further agree, upon request, to provide the other party with all information regarding the members of the Company Group that either party is required to report to any Governmental Authority.

(f) With respect to any Company Group member that is classified as a partnership for U.S. federal income tax purposes, Sellers and Purchaser agree, for U.S. federal income tax purposes, to treat Purchaser’s purchase of the Shares of such entity in a manner consistent with the holding in Situation 2 of Revenue Ruling 99-6, 1999-1 C.B. 432. Specifically, such acquisition will be treated (1) by Seller as if it had sold its Shares in such entity to Purchaser and (2) by Purchaser as if it had purchased the assets of such entity.

(g) Within 30 days after the Closing Date, Purchaser and Sellers shall use commercially reasonable efforts to prepare a schedule (the “Allocation Schedule”) allocating the Purchase Price and other consideration paid for the Shares, as adjusted pursuant to the terms of this Agreement and taking into account such further adjustments as required for applicable Tax purposes, among the Shares and further among the assets of any member of the Company Group treated as a partnership for U.S. federal income tax purposes in accordance with Section 751 and the requirements of Treasury Regulation § 1.1060-1, as applicable. If the parties are able to agree on such allocation within such time period, the parties shall report and file all Tax Returns consistent with the Allocation Schedule and shall take no Tax position contrary thereto or inconsistent therewith (including in any audits or examinations by any Governmental Authority).

(h) Within 90 days after the Closing Date, Sellers shall determine the amount of any additional Taxes due from Sellers in the event of an election under Section 338(h)(10) of the Code with respect to Purchaser’s acquisition of Aguasal and shall notify Purchaser of such amount. Within 30 days thereafter, Purchaser shall notify Sellers whether it desires for an election under Section 338(h)(10) of the Code to be made with respect to its acquisition of Aguasal, and if so, shall pay to Sellers an amount equal to the amount of such additional Taxes as determined pursuant to the preceding sentence. Failing such notification by the 120th day after the Closing Date, no such election shall be made with respect to such acquisition and Purchaser shall destroy the Section 338(h)(10) Election Forms received from Sellers at Closing.

(i) The parties agree that the Purchase Price is inclusive of all applicable sales or use Taxes applicable to the purchase and sale of the Shares, and any other transfer gross receipts, registration, and similar Taxes (including real estate transfer Taxes) (collectively, “Transfer Taxes”), if any, that are payable by any party hereto or any member of the Company Group arising out of or in connection with the consummation of the transactions contemplated by this Agreement shall be borne 50% by Sellers and 50% by Purchaser.

Section 4.14 No Solicitation of Transactions.

(a) At any time subsequent to the date of, and prior to termination of this Agreement under Article VI, the Sellers and Companies shall not, directly or indirectly, through any officer, director, agent or employee of, or any investment banker, financial advisor, attorney, accountant or other representative retained by, the Sellers, Companies or any of their respective Affiliates (each a “Seller Representative”) (i) solicit, initiate, seek or encourage (including by way of furnishing information or assistance) or take other action to facilitate any inquiries or the submission of any proposal which constitutes or may reasonably be expected to lead to, an Acquisition Proposal from any Person other than the Purchaser (a “Third Party”), or (ii) engage in any discussions or negotiations relating thereto or in furtherance thereof or accept any Acquisition Proposal. Any Seller or Company shall immediately communicate to the Purchaser the material terms of any written proposal (and the identity of the Person making such proposal) which it may receive, and such Seller or Company shall promptly deliver a copy of such proposal to the Purchaser. The Sellers and Companies agree not to release any Third Party from, or waive any provision of, any confidentiality agreement to which any Company is a party.

(b) Upon execution by the Sellers and Companies of this Agreement, each Seller Representative will terminate any solicitations, encouragement, activities, discussions and negotiations with any Person other than the Purchaser conducted heretofore by the Sellers, Companies or any Seller Representative with respect to any Acquisition Proposal until the earlier of Closing or termination of this Agreement pursuant to Article VI.

Section 4.15 Notification of Certain Matters. The Sellers, the Companies and the Purchaser shall each give prompt written notice to the other of (a) the occurrence, or failure to occur, of and shall provide accurate and complete copies of any and all information relating to, any event of which it becomes aware that has caused or that would be likely to cause any representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Closing, and (b) the failure of such, or any officer, director, employee, or agent of such party, to comply with or satisfy in any material respect any covenant, condition, or agreement to be complied with or satisfied by it hereunder. A notifying party under this Section 4.15 shall use all commercially reasonable efforts to cure, before the Closing, any occurrence of (a) or (b) in the proceeding sentence. No such notification shall affect the representations or warranties of the parties or the conditions to their respective obligations hereunder.

Section 4.16 Confidentiality. Sellers agree that until March 31, 2010, any facts, information, know-how, processes, trade secrets, customer lists or confidential matters that relate in any way to the Properties or the Companies shall be maintained in confidence and shall not be divulged by the Sellers or their respective Affiliates to any party unless and until they shall become public knowledge (other than by disclosure in breach of this Section 4.16) or as required by applicable Laws, including applicable securities laws and regulations; provided, before any Sellers or any of their respective Affiliates discloses any of the foregoing as may be required by applicable Laws, such Person shall give the Purchaser reasonable advance notice to the extent practicable and give Purchaser an opportunity to take such reasonable actions to minimize the required disclosure. In the event this Agreement is terminated for any reason, the parties hereto acknowledge and agree that the Confidentiality Agreement shall remain in full force and effect in accordance with its terms. For purposes of clarity, Purchaser acknowledges that any environmental reports or analysis conducted by Purchaser on the Properties between the date of this Agreement and the Closing or termination of this Agreement shall constitute “Confidential Information” for purposes of the Confidentiality Agreement and Purchaser shall convey any environmental reports to Sellers promptly following termination, and shall convey any other due diligence materials that constitute

Confidential Information to the Sellers upon request, in each case in the event that this Agreement is terminated pursuant to Article VI.

Section 4.17 Releases and Termination. At the Closing, each of the Sellers and the Companies will execute mutual releases from any and all obligations (including indemnification obligations) and Claims, known and unknown, that have accrued or may accrue and that relate to acts or omissions prior to the Closing Date, including any and all damages, whether such obligations, Claims or damages arise in tort, contract or statute, including obligations, Claims or damages (a) arising under each Company’s Organizational Documents and (b) relating to actions or omissions of any Company or any Seller, or any acts or omissions of the managers, directors, shareholders, officers or members (former or present) including those committed while serving in their capacity as managers, shareholders, directors, officers, members, employees or similar capacities of any Company, and including in each case any and all Claims which such Seller does not know or suspect to exist in his, her or its favor as of the date hereof or as of the Closing or any Claims that a Company may have against a Seller. Notwithstanding anything herein to the contrary, nothing in this Section 4.17 or the release contemplated herein shall limit in any way the right of Purchaser or any Purchaser Indemnified Party to enforce this Agreement or seek damages permitted by this Agreement, including the right to indemnification contemplated by Article VII or any right of the Sellers to seek indemnification under Article VII. Effective upon the Closing, each Seller waives any preemptive rights that he may have, or ever had, with respect to any interest in the Companies and waives any right such Seller may have under the Companies’ Organizational Documents or otherwise to acquire any interest in the Companies being transferred pursuant to, or as contemplated by, this Agreement or any transfer that occurred prior to the date hereof. THE RELEASES WILL APPLY TO ALL CLAIMS, AND THE SELLERS AND THE COMPANIES WILL AGREE TO WAIVE THE BENEFITS OF ANY LAW (INCLUDING PRINCIPLES OF COMMON LAW) OF ANY STATE OR TERRITORY OR OTHER JURISDICTION OF THE UNITED STATES OR OF ANY JURISDICTION OUTSIDE OF THE UNITED STATES THAT PROVIDES THAT A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN SUCH PARTY’S FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY SUCH PARTY MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Section 4.18 Identity of Purchaser. Sellers are contracting for the sale of the Shares to Purchaser, a Delaware corporation. Therefore, Purchaser covenants and agrees that it will not assign this Agreement to any Affiliate or Subsidiary or permit any Affiliate or Subsidiary to pay the Purchase Price to Sellers unless such Affiliate or Subsidiary is a corporation or limited liability company not organized under the laws of the State of Texas.

(b) by Purchaser if there has been a material breach by any Seller or any Company of any representation, warranty or covenant contained in this Agreement which cannot be, or has not been, cured within fifteen (15) days after written notice of such breach is given to such Seller, provided that the right to effect such cure shall not extend beyond the Termination Date and provided further that such breach relates to a representation or warranty that survives Closing pursuant to Section 7.1;

(c) by the Sellers if there has been a material breach by Purchaser of any representation, warranty, or covenant contained in this Agreement which cannot be, or has not been, cured within fifteen (15) days after written notice of such breach is given to Purchaser, provided that the right to effect such cure shall not extend beyond the Termination Date;

(d) by Purchaser, if all conditions of Closing set forth in Section 5.2 of this Agreement have not been satisfied or waived by the Termination Date, provided, however, that Purchaser shall not be entitled to terminate this Agreement pursuant to this paragraph (d) if it is in material violation of any of its representations, warranties or covenants contained in this Agreement or such failure shall be due to the failure of Purchaser to perform or comply with any of the covenants, agreements or conditions hereof to be performed or complied with by it prior to the Closing;

(e) by the Sellers, if all conditions of Closing set forth in Section 5.3 of this Agreement have not been satisfied or waived by the Termination Date, provided, however, that the Sellers shall not be entitled to terminate this Agreement pursuant to this paragraph (e) if any of them is in material violation of any of its representations, warranties, or covenants contained in this Agreement or such failure shall be due to the failure of any Seller to perform or comply with any of the covenants, agreements or conditions hereof to be performed or complied with by it prior to the Closing;

(f) by any party hereto if any Governmental Authority shall have issued an order, decree or ruling or taken any other action permanently enjoining, restraining or otherwise

Section 6.2 Effect of Termination. Upon termination of this Agreement pursuant to this Article VI, this Agreement shall be void and of no effect except as to Section 4.16, and shall result in no obligation of or liability to any party or their respective directors, officers, managers, employees, agents or stockholders for damages, penalties or liquidated damages; provided that: (1) if this Agreement is terminated as a result of an intentional breach of any representation, warranty or covenant in this Agreement, the party who breached the representation, warranty or covenant shall be liable to the other parties for actual damages, including all costs and expenses incurred in connection with the preparation, negotiation, execution and performance of this Agreement, and (2) if on the Closing Date all conditions to Closing set forth in Section 5.2 are satisfied and (A) Purchaser fails to complete the Transactions in violation of this Agreement or (B) Sellers terminate this Agreement pursuant to Section 6.1(e) because the conditions set forth in Sections 5.3(a), (c), (d) and (e) have not been satisfied, Purchaser agrees to pay as liquidated damages to Sellers and not as a penalty the amount of $20,000,000.00 as compensation to Sellers for their losses as a result of Purchaser’s breach of this Agreement, as the amount of damages suffered by Sellers in such circumstance would be impossible to calculate (the “Reverse Break Fee”). In the event of the occurrence of the forgoing clause (2), Sellers and Purchaser agree that the payment of the Reverse Break Fee by Purchaser shall be the sole and exclusive remedy of Sellers for such breach, and Sellers shall not be entitled to seek actual damages from Purchaser or seek specific performance to enforce this Agreement against Purchaser.

(collectively, a “Purchaser Indemnified Party”) from and against any and all losses, costs, damages, expenses and liabilities of whatever nature or kind (including attorney’s fees, litigation and court costs and costs to mitigate any damages in accordance with Section 7.2(g)) (collectively, “Losses”) incurred by a Purchaser Indemnified Party and resulting from, arising out of, or relating to any of the following described matters (herein collectively referred to as the “Seller Indemnified Liabilities,” and individually as a “Seller Indemnified Liability”):

(i) any of the representations or warranties, other than the Terminating Representations, made by any Seller contained in this Agreement not having been true and correct as of the Closing Date (or as of the specified date in the case of representations and warranties being made only as of a certain date);

(ii) a breach of any covenant or obligation of a Seller in this Agreement;

(iii) the Xxxxx Holding Distribution and the Xxxxx Energy Distribution (excluding any Taxes that are incurred as a result of such transactions for which Sellers are liable pursuant to Section 4.13) and the ownership or operation of the Excluded Companies or their assets, whether arising before or after the Closing; and

(iv) any long-term debt (including the current portion thereof) of the Companies in existence as of the Closing.

The parties hereto acknowledge that no Company will be responsible in any manner for the indemnification obligations of the Sellers hereunder.

(b) Purchaser agrees to indemnify and hold harmless each Seller and their respective trustees, administrators, heirs, personal representatives, successors and assigns (collectively, the “Seller Indemnified Party”) from and against any and all Losses incurred by such Seller Indemnified Party, resulting from, arising out of, or relating to (i) any of the representations or warranties made by Purchaser contained in this Agreement not having been true and correct as of the Closing Date, (ii) a breach of any covenant or obligation of Purchaser in this Agreement or (iii) any liability or obligation arising out of the ownership or operation of the Companies or their assets or the Properties after the Closing Date.

(c) Notwithstanding the foregoing, (i) no claim may be made for indemnification pursuant to Section 7.2(a)(i), 7.2(a)(ii), 7.2(b)(i) or 7.2(b)(ii), unless and until the aggregate of all Losses of the Purchaser Indemnified Party pursuant to Sections 7.2(a)(i) and 7.2(a)(ii), on the one hand, or the Seller Indemnified Party pursuant to Sections 7.2(b)(i) and 7.2(b)(ii), on the other hand, as the case may be, exceed $3,000,000.00 (the “Indemnification Threshold Amount”), in which event the Purchaser Indemnified Party or the Seller Indemnified Party, as the case may be, shall be entitled to seek indemnity for the amount by which such Losses for which indemnification is provided hereunder exceed the Indemnification Threshold Amount, and (ii) in no event shall the aggregate amount of Losses for which the Seller Indemnified Party pursuant to Sections 7.2(b)(i) and 7.2(b)(ii), on the one hand, or the Purchaser Indemnified Party pursuant to Sections 7.2(a)(i) and 7.2(a)(ii), on the other hand, be entitled to indemnification exceed the amount of $20,000,000.00 (the “Maximum Liability”). Notwithstanding the foregoing, (A) any Losses suffered by a Purchaser Indemnified Party arising under Section 7.2(a)(i) as a result of a breach of the representations and warranties set forth in Sections 3.1(a), 3.1(b) or 3.1(f), or any Losses suffered by a Seller Indemnified Party arising under Section 7.2(b)(i) as a result of a breach of the representations and warranties set forth in Sections 3.2(a) or 3.2(b), in each case shall not be subject to the limitations imposed by the Indemnification Threshold Amount or the

Maximum Liability, but in each case the Purchaser Indemnified Party and the Seller Indemnified Party shall not recover damages in excess of the sum of the Purchase Price, (B) any Losses suffered by a Purchaser Indemnified Party arising under Section 7.2(a)(ii) as a result of a breach of the covenant set forth in Section 4.4 shall not be subject to the limitations imposed by the Indemnification Threshold Amount so long as such Claim for indemnification is made on or before December 31, 2008 and (C) any Losses suffered by a Purchaser Indemnified Party arising under Section 7.2(a)(ii) as a result of a breach of the covenants set forth in Section 4.13(c)(ii)(A) shall not be subject to the limitations imposed by the Indemnification Threshold Amount or the Maximum Liability. Notwithstanding anything herein to the contrary, in no event shall the foregoing limitations limit any claims for indemnification under Section 7.2(a)(i), 7.2(a)(ii), 7.2(b)(i) or 7.2(b)(ii) in the event of fraud or criminal intent by the indemnifying party, but in no event shall an indemnified party be entitled to recover damages in excess of the Purchase Price. In no event shall “Loss” or “Losses” under this Article VII include lost profits, consequential or special or punitive damages or penalties unless the indemnified party has become liable for such damages as a result of a third-party claim, in which case such indemnified party may recover such damages from the indemnifying party as actual damages.

(d) The amount of Losses for which an Indemnified Party is entitled to indemnification shall be reduced by any insurance recoveries or other indemnities, contributions or similar payments actually recovered from any third party as a result of the incurrence of such Losses or the facts or circumstances giving rise thereto (including with respect to Losses resulting from the split off of Summit Petroleum Management Corporation, f/k/a Team Operating Corporation, any recoveries or reimbursements of Taxes under the agreement governing such split off transaction).

(e) All claims for indemnification under this Article VII shall be asserted and resolved as follows:

(i) In the event that any claim or demand for which the Sellers could be liable to a Purchaser Indemnified Party hereunder is asserted against or sought to be collected from a Purchaser Indemnified Party by a third party, the Purchaser Indemnified Party shall promptly notify Agent of such claim or demand, specifying the nature of such claim or demand and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim or demand) (the “Claim Notice”); provided, however, that any failure or delay in sending a Claim Notice shall not relieve the Sellers from liability hereunder except to the extent the Sellers are materially prejudiced by such failure or delay. The Sellers shall have 10 days from their receipt of the Claim Notice (the “Notice Period”) to notify the Purchaser Indemnified Party (i) whether or not they dispute their liability to the Purchaser Indemnified Party hereunder with respect to such claim or demand and (ii) whether or not they desire, at their sole cost and expense, to defend the Purchaser Indemnified Party against such claim or demand. In the event that the Sellers notify the Purchaser Indemnified Party within the Notice Period that they do not dispute their liability to the Purchaser Indemnified Party hereunder and that they desire to defend the Purchaser Indemnified Party against such claim or demand, except as hereinafter provided, the Sellers shall have the right to defend the Purchaser Indemnified Party by appropriate proceedings, which proceedings shall be promptly settled or prosecuted by them to a final conclusion in such a manner as to avoid any risk of the Purchaser Indemnified Party becoming subject to liability for any other matter. If a Purchaser Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. Sellers shall not settle or compromise any third-party claim or

demand without the prior written consent of the Purchaser Indemnified Party if such settlement or compromise would restrict Purchaser or otherwise adversely affect Purchaser in any way, which consent shall not be unreasonably withheld or delayed. If, in the reasonable opinion of the Purchaser Indemnified Party, any such claim or demand involves an issue or matter which could have a material adverse effect on the business, operations, properties, assets or prospects of the Purchaser Indemnified Party, such claim or demand seeks injunctive or other non-monetary relief against such Purchaser Indemnified Party or such claim or demand is reasonably likely to result in Losses for which Sellers may not be obligated to indemnify under this Agreement (including if the amount of such Loss is reasonably likely to exceed the Maximum Liability), the Purchaser Indemnified Party shall have the right to control the defense or settlement of any such claim or demand; however, its costs and expenses in so doing shall not be included as part of the indemnification obligations of the Sellers hereunder. If the Purchaser Indemnified Party should elect to exercise such right, the Sellers shall have the right to participate in, but not control, the defense or settlement of such claim or demand at the sole cost and expense of the Sellers. If the Sellers elect not to defend the Purchaser Indemnified Party against such claim or demand, whether by not giving the Purchaser Indemnified Party timely notice as provided above or otherwise, then the amount of any such claim or demand, or, if the same be contested by the Sellers or by the Purchaser Indemnified Party (but the Purchaser Indemnified Party shall have no obligation to contest any such claim or demand), then that portion thereof as to which such defense is unsuccessful shall be conclusively deemed to be a liability of the Sellers hereunder. If the Purchaser Indemnified Party controls the defense of any claim or demand, the Purchaser Indemnified Party shall not settle or compromise such third-party claim or demand without the prior written consent of the Agent, which consent shall not be unreasonably withheld or delayed; provided, however, the Purchaser Indemnified Party shall not be required to obtain the consent of the Agent if the Sellers are not obligated to make any indemnification payments under this Article VII as a result of such settlement or compromise or such settlement or compromise does not restrict or otherwise adversely affect any Seller in any way.

(ii) In the event a Purchaser Indemnified Party should have a claim against the Sellers hereunder which does not involve a claim or demand being asserted against or sought to be collected from it by a third party, the Purchaser Indemnified Party shall promptly send a Claim Notice with respect to such claim to the Agent. If the Sellers do not notify the Purchaser Indemnified Party within the Notice Period that they dispute such claim, it shall be conclusively deemed a liability of Sellers hereunder.

(iii) All claims for indemnification by a Seller under this Agreement shall be asserted and resolved under the procedures set forth above, substituting in the appropriate place “Seller Indemnified Party” for “Purchaser Indemnified Party” and variations thereof and “Purchaser” for “Sellers” and “any Company” and variations thereof.

(f) For federal income tax purposes, the parties agree to treat (and shall cause each of their respective affiliates to treat) any indemnity payment under this Agreement as an adjustment to the consideration payable to the Sellers pursuant to Article II hereof unless a final and nonappealable determination by an appropriate Governmental Authority (which shall include the execution of an IRS Form 870-AD or successor form) provides otherwise.

(g) Each party hereto agrees to use, and to cause its Affiliates to use, commercially reasonable efforts to mitigate any Losses incurred or to be incurred by such party or its Affiliates

upon and after becoming aware of any event which could reasonably be expected to give rise to any Loss. Any costs or expenses incurred as a result of the foregoing efforts to mitigate any Losses shall be included as Losses for purposes of this Article VII.

(h) After the Closing has occurred, subject to the purchase right afforded to Purchaser in Section 4.12(d), the right to indemnification under this Article VII shall be the sole remedy of each party hereto in connection with any breach by the other party of is representations, warranties, covenants or agreements contained herein or in any agreement delivered by any Seller or Purchaser pursuant to this Agreement.

Section 7.3 Express Negligence. THE PARTIES HERETO INTEND THAT THE INDEMNITIES SET FORTH IN THIS ARTICLE VII BE CONSTRUED AND APPLIED AS WRITTEN ABOVE, NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY. WITHOUT LIMITING THE FOREGOING, BUT LIMITED TO THE EXTENT PROVIDED ABOVE, SUCH INDEMNITIES SHALL APPLY NOTWITHSTANDING ANY STATE’S “EXPRESS NEGLIGENCE” OR SIMILAR RULE THAT WOULD DENY COVERAGE BASED ON AN INDEMNIFIED PARTY’S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. IT IS THE INTENT OF THE PARTIES THAT, TO THE EXTENT PROVIDED ABOVE, THE INDEMNITIES SET FORTH IN THIS ARTICLE VII SHALL APPLY TO AN INDEMNIFIED PARTY’S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. THE PARTIES AGREE THAT THIS PROVISION IS “CONSPICUOUS” FOR PURPOSES OF ALL STATE LAWS.
