(a)    Upon execution of this Agreement until the Closing, Seller shall give Purchaser, its Affiliates and each of their respective officers, agents, accountants, attorneys, investment bankers, environmental consultants and other authorized representatives (“Purchaser’s Representatives”) reasonable access to the Records in Seller’s possession and any Gathering System or Asset owned or operated by the Company or any Subsidiary, in each case during, as applicable, Seller’s, the Company’s and the Subsidiary’s normal business hours, for the purpose of conducting a confirmatory review of the Gathering System or Asset, in each case to the extent that Seller may provide such access without (i) violating applicable Laws or breaching any Contracts, (ii) waiving any legal privilege of Seller, any of its Affiliates, or its counselors, attorneys, accountants, or consultants, or (iii) violating any obligations to any Third Party. Such access shall be granted to Purchaser on the premises of the Gathering System or Asset that are operated by the Company or any Subsidiary. All investigations and due diligence conducted by Purchaser or any of Purchaser’s Representatives with respect to the Gathering System or Asset shall be conducted at Purchaser’s sole cost, risk and expense and any conclusions made from any examination done by Purchaser or any of Purchaser’s Representatives shall result from Purchaser’s own independent review and judgment. Seller, the Company or any of their designees shall have the right to accompany Purchaser and Purchaser’s Representatives whenever they are on site on the Gathering System. Purchaser’s investigation and review shall be conducted in a manner that minimizes interference with the ownership or operation of the Gathering System or the Business. Prior to Closing, Purchaser and Purchaser’s Representatives shall have the right to conduct one or more determinations of the volumes of Inventory in the Gathering System at Purchaser’s sole cost and expense and in accordance with standard industry practice. Purchaser’s inspection right with respect to the environmental

condition of the Gathering System or Asset shall be limited to conducting a Phase I Environmental Site Assessment in accordance with the American Society for Testing and Materials (A.S.T.M.) Standard Practice Environmental Site Assessments: Phase I Environmental Site Assessment Process (Publication Designation: E1527‑13), which may include, in addition, environmental compliance reviews, or a similar visual assessment that does not include sampling or testing of any environmental media (“Phase I”). Purchaser shall not be entitled to conduct any Phase II Environmental Site Assessments similar to A.S.T.M. Standard Practice Environmental Site Assessments: Phase II Environmental Site Assessment Process (Publication Designation: E1903‑11), or any other invasive or intrusive testing, or sampling on or relating to the Gathering System (“Phase II”), without the prior written consent of Seller, such consent to be granted, conditioned, or withheld at the sole discretion of Seller. If permitted, Purchaser shall furnish to Seller and the Company, free of costs and without warranty, a copy of all draft and final reports and test results prepared by or for Purchaser related to Purchaser’s diligence and investigation of the Gathering System or Asset, including any and all Phase I, Phase II, or further environmental assessments relating to any of the Gathering System as soon as reasonably possible after such report is prepared. Purchaser shall obtain from any applicable Governmental Authorities and Third Parties all permits necessary or required to conduct any approved invasive activities permitted by Seller. Seller shall have the right, at its option, to split with Purchaser any samples collected pursuant to approved invasive activities. If the Closing does not occur, Purchaser (1) shall promptly return to Seller or destroy all copies of the Records, reports, summaries, evaluations, due diligence memos and derivative materials related thereto in the possession or control of Purchaser or any of Purchaser’s Representatives and (2) shall keep and shall cause each of Purchaser’s Representatives to keep, any and all information obtained by or on behalf of Purchaser confidential, except, in each case, as otherwise required by Law. No investigation by Purchaser shall operate as a waiver of or otherwise effect any representation, warranty, covenant or agreement of Seller hereunder.

(b)    Purchaser may not contact customers or potential customers of the Company or any of its Subsidiaries with respect to their relationship with the Company and the Subsidiaries without the prior written consent of Seller (which consent shall not be unreasonably withheld, conditioned or delayed).

(c)    Purchaser agrees to indemnify, defend and hold harmless each member of the Seller Group and all such Persons’ stockholders, members, managers, officers, directors, employees, agents, lenders, advisors, representatives, accountants, attorneys and consultants from and against any and all Damages (including court costs and reasonable attorneys’ fees), including Damages attributable to, arising out of or relating to access to the Records, any offices of Seller, or the Assets prior to the Closing by Purchaser or any of Purchaser’s Representatives, EVEN IF SUCH CLAIMS, DAMAGES, LIABILITIES, OBLIGATIONS, LOSSES, COSTS AND EXPENSES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF ANY MEMBER OF THE SELLER GROUP.

(d)    Upon completion of Purchaser’s due diligence, Purchaser shall, at its sole cost and expense and without any cost or expense to Seller, Company or any of their respective Affiliates, (i) repair all damage done to the Assets in connection with Purchaser’s due diligence, (ii) restore the Assets to the approximate same or better condition than they were prior to commencement of Purchaser’s due diligence and (iii) remove all equipment, tools or other property brought onto the Assets in connection with Purchaser’s due diligence. Any disturbance to the Assets

(including the leasehold associated therewith) resulting from Purchaser’s due diligence shall be promptly corrected by Purchaser.

(e)    During all periods that Purchaser or any of Purchaser’s Representatives are on the Assets, Seller’s premises or Company’s premises, Purchaser shall maintain, at its sole expense and with insurers reasonably satisfactory to Seller, policies of insurance of the types and in the amounts reasonably requested by Seller. Coverage under all insurance required to be carried by Purchaser hereunder shall (i) be primary insurance, (ii) list the members of the Seller Group as additional insureds, (iii) waive subrogation against the members of the Seller Group and (iv) provide, to the extent available, for five (5) days prior notice to Seller in the event of cancellation or modification of the policy or reduction in coverage.

(f)    Purchaser understands that Seller has had discussions with the management of the Company and its Subsidiaries regarding other bids for the Company, the Subsidiaries and/or the Assets and the preparation and negotiation of this Agreement, the Schedules hereto and the other documents contemplated herein, and that, (i) except to the extent discovery rules would otherwise permit review of such information by Purchaser or the Company if such information were in the possession of Seller and (ii) excluding information related to this Agreement (including the representations and warranties and covenants set forth herein and the Schedules and Exhibits attached hereto), (A) Purchaser and the Company shall not be entitled to use in connection with any disputes against Seller or the Company and its Subsidiaries (before or after Closing) any of Seller’s or the Company’s internal drafts of this Agreement, copies of (or other information regarding) other bids for the Company and its Subsidiaries or emails or other written information (including in electronic form) relating to any of the foregoing or to the sales process (whether or not related to the Purchaser’s bid or other bids for the Company and its Subsidiaries) and (B) each of the Purchaser and the Company hereby agree that (1) it shall not have any rights to any such information and (2) it shall not request any of the Company or its Subsidiaries, their management to provide to any such information.

Notwithstanding the foregoing provisions of this Section 7.2, Seller shall not be in breach of this Section 7.2 (i) if, notwithstanding Seller’s vote under the LLC Agreement of the Subject Securities to the contrary, the Company or any of its Subsidiaries take any of the actions set forth in this Section 7.2 without the consent of Purchaser or (ii) in the event of an emergency or risk of loss, damage or injury to any Person, property or the environment or as otherwise required by Law, Seller may take such actions as are reasonably necessary to address such emergency, risk or requirements and shall notify Purchaser of such action promptly thereafter.

Section 7.4    Closing Efforts and Further Assurances; Non-Solicitation.

(a)    Each Party agrees that from and after the Execution Date, it will not voluntarily undertake any course of action inconsistent with the provisions or intent of this Agreement, and will use its commercially reasonable efforts to take, or cause to be taken, all action

and to do, or cause to be done, all actions reasonably necessary, proper or advisable under applicable Laws to cause the closing conditions hereunder to be satisfied and to consummate the transaction contemplated hereunder, including (i) using its commercially reasonable efforts to cooperate with the other Party to cause to be lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the Parties to consummate the transaction contemplated hereunder, (ii) executing any additional instruments and agreements necessary to consummate the transactions contemplated by this Agreement and (iii) using commercially reasonable efforts to facilitate the closing of the transactions contemplated by the Class A Purchase Agreement.

Seller agrees that the rights and remedies for noncompliance with this Section 7.4(b) shall include having such provision specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to Purchaser and that money damages would not provide an adequate remedy to Purchaser.

Purchaser shall notify Seller promptly after a discovery by Purchaser that any representation or warranty of Seller contained in this Agreement is, becomes or will be untrue in any material respect on or before the Closing Date. Seller shall notify Purchaser promptly after a discovery by Seller that any representation or warranty of Purchaser contained in this Agreement is, becomes or will be untrue in any material respect on or before the Closing Date. It is understood and agreed that the delivery of any notice required under this Section 7.5 shall not in any manner constitute a waiver by any Party of any conditions precedent to the Closing hereunder.

prior to the Closing shall be deemed to have been included in the Disclosure Schedules for the purposes of any claims made by Purchaser under this Agreement.

Section 7.7    Government Reviews.

(a)    From and after the Execution Date until the Closing, subject to the terms and conditions of this Agreement, each of Purchaser and Seller shall, and shall cause their respective Affiliates to, undertake commercially reasonable efforts to make or cause to be made promptly (and, in the case of filings required to be made pursuant to the HSR Act, not later than January 30, 2017) the filings required of such Party or any of its Affiliates under any Laws with respect to the transactions contemplated by this Agreement and to pay any fees due of it in connection with such filings; provided, however, that all filing fees payable to any Governmental Authorities relating to filings required to be made pursuant to the HSR Act shall be paid and borne by Purchaser.

Purchaser shall, and shall cause its Affiliates to use commercially reasonable efforts to contest and resist any action or proceeding instituted (or threatened in writing to be instituted) by any Governmental Authority challenging the transactions contemplated

by this Agreement as in violation of any Law; provided, that Purchaser shall not be required to contest or resist such action or proceeding if the Parties reasonably expect that Purchaser would incur costs and expenses in excess of Three Million Dollars ($3,000,000.00) in connection therewith. Notwithstanding the foregoing or anything in this Agreement to the contrary, in no event shall Purchaser or any of its Affiliates be required to commit to take any action pursuant to this Section 7.7(b) the consummation of which is not conditioned on the Closing of the transaction contemplated by this Agreement.

Section 7.12    Indemnification; Directors’ and Officers’ Insurance.

(a)    Purchaser agrees that all rights to indemnification for acts or omissions occurring prior to the Closing Date in favor of the current or former managers, directors, officers, partners, members, employees, agents and fiduciaries of the Company (collectively, the “Company Indemnitees”) as provided as of the date hereof in the respective organizational documents of the Company shall survive the transactions contemplated by this Agreement and shall continue in full force and effect in accordance with their terms for a period of not less than four (4) years from the Closing Date. Purchaser shall not, and shall cause its respective Affiliates (including the Company after the Closing) not to repeal or amend such arrangements in any manner that would adversely affect the rights of the Company Indemnitees thereunder.

(b)    In the event that Purchaser or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, in each such case, to the extent such assumption does not occur by operation of Law, proper provisions shall be made so that the successors and assigns of Purchaser shall assume the obligations set forth in Section 7.12(a). The provisions of this Section 7.12 are intended to be for the benefit of, and shall be enforceable by, the Parties and each Person entitled to indemnification or expense advancement pursuant to this Section 7.12, and his or its heirs and representatives.

(c)    The obligations of Purchaser under this Section 7.12 shall not be terminated or modified in such a manner as to adversely affect any Company Indemnitee to whom this Section 7.12 applies without the consent of such Company Indemnitee so adversely affected.

Section 7.13    Seller Employee Matters.

(a)    Seller shall, to the extent not prohibited by applicable Law, use commercially reasonable efforts to provide to Purchaser no later than ten (10) Business Days following the Execution Date the following information with respect to each Business Employee: (i) employment status including (A) whether actively at work or on leave, (B) whether a full-time or part-time employee (along with a brief explanation of how the Seller defines those terms for purposes of making such classifications) and (C) whether classified as exempt or nonexempt, (ii) job title, (iii) date or dates of hire/rehire, (iv) date of birth, (v) annualized salary or base hourly wage rate, (vi) bonus opportunity for the 2016 calendar year and (vii) work location.

Purchaser has complete discretion in determining whether to offer to employ any Business Employee designated and interviewed for Purchaser. In no event shall Seller have any obligations to cause any Business Employee, and no Business Employee shall have any obligation, to (i) be available or conduct any interview with Purchaser or any representative of Purchaser or (ii) accept employment with any Person, Purchaser may refuse to offer employment to, or hire, any Business Employee designated and interviewed for Purchaser for any reason including, without limitation, for failing to satisfy Purchaser’s standard employee screening and employment process and procedures. No later than ten (10) Business Days prior to the Closing Date, Purchaser or one of its Affiliates may make offers of employment to the Business Employees of its choosing. Each such offer shall be subject to and conditioned upon the Business Employee accepting the offer not later than five (5) days following the date on which the offer is communicated to the Business Employee, and will be for employment as of the later of (A) the Closing Date or (B) if such Business Employee is on a leave of absence, such date such Business Employee returns from such leave of absence (so long as such return occurs within one hundred eighty (180) days after the Closing or such later time as may be required by applicable Law). Each such employment offer shall be subject to and conditioned on the occurrence of the Closing. Nothing in this Agreement will require Purchaser to implement or maintain any specific benefit plans or amend any Purchaser Benefit Plan. The date of a Business Employee’s commencement of active employment with Purchaser or its Affiliate is referred to as his or her “Hire Date”.

(c)    For purposes of this Agreement, a “Transferred Employee” is a Business Employee who accepts an offer of employment from Purchaser or one of its Affiliates made pursuant to Section 7.13(b) and becomes employed by Purchaser or one of its Affiliates pursuant to the process set forth in Section 7.13(b). With respect to each Transferred Employee, effective as of the time immediately prior to such Transferred Employee’s Hire Date, Seller or its Affiliates shall terminate the employment of such Transferred Employee. Subject to the terms of this Section 7.13, all Transferred Employees shall be employed pursuant to, and subject to, Purchaser’s and its Affiliates policies and procedures applicable to similarly situated new hires and employees.

(d)    Effective from and after the respective Hire Date, for purposes of each of the employee benefit plans of Purchaser or any of its Affiliates (“Purchaser Benefit Plan”) providing medical, dental, prescription drug and/or vision benefits in which the Transferred Employees are eligible to participate following the respective Hire Date, if applicable and to the extent permitted by applicable Law, Purchaser shall, or shall cause its Affiliates to, take commercially reasonable efforts to (i) waive any limitation on health and welfare coverage of any Transferred Employee and his or her eligible dependents due to pre-existing conditions or waiting periods, active employment requirements and requirements to show evidence of good health under such Purchaser Benefit Plan to any Transferred Employee to the extent required by Law or permitted by the Purchaser Benefit Plans and (ii) obtain credit under the Purchaser Benefit Plans for each Transferred Employee for

any co-payments and deductibles paid by such Transferred Employee and his or her covered dependents prior to such Hire Date and in the same plan year in which such Hire Date occurs towards satisfying the applicable annual deductibles and annual out-of-pocket limits, in each case, to the extent consistent with the then-existing terms of such Purchaser Benefit Plan and, in the case of (ii), to the extent Seller provides to Purchaser the information reasonably necessary for Purchaser to comply with the requirements of that provision.

(e)    Seller, or its Affiliate that employees the Transferred Employee, will retain sole responsibility and liability for all compensation and benefits payable with respect to the services provided by the Transferred Employee to Seller, its Affiliate or the Company and its Subsidiaries prior to the Closing or, if later, the termination of the individuals employment with Seller or its Affiliate, including, without limitation, any severance benefits payable under any Seller Benefit Plans. The Parties agree that Purchaser does not and will not assume any liability with respect to the Transferred Employees under any of the Seller Benefit Plans, including any obligations with respect to severance benefits, unused vacation days or paid time off days.

(f)    Purchaser sponsors various employee benefit plans, including plans providing medical, dental, prescription drug and/or vision benefits and a defined contribution plan that is tax-qualified under Section 401(a) of the Code and that contains a Section 401(k) feature and allows certain rollover contributions from eligible participants (the “Purchaser 401(k) Plan”). Purchaser or one of its Affiliates shall cause the Purchaser 401(k) Plan to accept the direct rollover of each Transferred Employee’s account distributed from the Seller 401(k) Plan (excluding any notes representing participant loans), but only to the extent acceptance of direct rollovers and receipt of notes representing participant loans are permitted under the terms of the Purchaser 401(k) Plan and Seller has provided a complete and accurate copy of the determination letter described in Section 3.9(c). Each Transferred Employee will be allowed to participate in the Purchaser Benefit Plans if, and to the extent, the Transferred Employee qualifies and is eligible to participate in such plans on a comparable basis to other similarly situated new hires.

(g)    Prior to and on the Closing Date, Seller take all actions required of Seller under the Worker Adjustment and Retraining Notification Act (the “WARN Act”) to the extent the WARN Act applies to Seller with respect to the transactions contemplated by or resulting from this Agreement.

(h)    In the event the Call Option Exercise does not occur and this Agreement is terminated, for the period commencing on the Termination Date and ending on the date that is two (2) years after (i) the Closing Date in the event Closing occurs and (ii) the Termination Date in the event this Agreement is terminated in accordance with the terms hereof (the “Non-Solicit Period”) Purchaser shall not, and shall cause each of its Affiliates not to, in any way directly or indirectly solicit, induce, hire, retain or attempt to hire or retain any employee of Seller or its Affiliates (other than as expressly permitted under this Section 7.13 with respect to the Business Employees in the event that the Closing occurs); provided, however, that (A) the foregoing shall not apply to generalized searches for employees by use of advertisements in the media that are not targeted at employees of Seller or any of its Affiliates and (B) Purchaser shall not be restrained from hiring employees whose employment by Seller or any of its Affiliates has terminated prior to commencement of employment solicitations or discussions.

(i)    The provisions of this Section 7.13 are solely for the benefit of the Parties and nothing in this Section 7.13, express or implied, shall confer upon any Business Employee or legal representative or beneficiary thereof, or upon any other Person, any rights or remedies, including any right to employment or continued employment for any specified period, or compensation or benefits of any nature or kind whatsoever under this Agreement. Nothing in this Section 7.13, express or implied, shall be (i) deemed an amendment of a Seller Benefit Plan providing benefits to any Business Employee, (ii) deemed an amendment of a Purchaser Benefit Plan providing benefits to any Transferred Employee or (iii) construed to prevent Purchaser or its Affiliates from terminating or modifying to any extent or in any respect any employee benefit plan that Purchaser or its Affiliates may establish or maintain.

Section 7.14    Escrow Agreement.

transactions contemplated hereunder or thereunder, or the condition, quality, status or nature of any Assets, INCLUDING RIGHTS TO CONTRIBUTION UNDER CERCLA OR ANY OTHER ENVIRONMENTAL LAW, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE POLICIES ISSUED OR UNDERWRITTEN BY ANY MEMBER OF THE PURCHASER GROUP OR THE SELLER GROUP, AS APPLICABLE, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEES OR THIRD PARTIES. No Party or Person is asserting the accuracy, completeness or truth of any representation and warranty set forth in this Agreement; rather, the Parties have agreed that should any representation or warranty of any Party prove inaccurate, incomplete or untrue, the other Party shall have the specific rights and remedies herein specified as the exclusive remedy therefor, but that no other rights, remedies or causes of action (whether in Law or in equity or whether in contract or in tort or otherwise) are permitted to any Party as a result of the failure, breach, inaccuracy, incompleteness or untruthfulness of any such representation and warranty.

(b)    Any claim for indemnity under this Article 12 by any current or former Affiliate, stockholder, member, officer, director, employee, agent, lender, advisor, representative, accountant, attorney and consultant of any Party must be brought and administered by the applicable Party to this Agreement. No Indemnified Person other than Seller and Purchaser shall have any rights against Seller or Purchaser under the terms of this Article 12, except as may be exercised on its behalf by Purchaser or Seller, as applicable, pursuant to this Article 12. Seller and Purchaser may elect to exercise or not exercise indemnification rights under this Agreement on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section 12.4.

(c)    The amount of any Damages for which a Party or any member of the Purchaser Group or the Seller Group, as applicable, is entitled to indemnity under this Article 12 shall be reduced by the amount of insurance or other third party proceeds, recoupment, reimbursements or claims realized by Purchaser or applicable members of the Purchaser Group (including Company and any Subsidiary) or the Seller Group, as applicable, under the relevant insurance arrangements, agreements, contracts or applicable Laws with respect to such Damages, less all costs of pursuing such claim. Each Party shall use, and shall cause its Affiliates to use, commercially reasonable efforts to pursue and prosecute any and all claims against Third Parties (including against Concho under the terms of the Class A Purchase Agreement) for which such Party or any member of the Purchaser Group (including Company and any Subsidiary) or the Seller Group, as applicable, is entitled to indemnification or defense from the other Party under this Article 12. In the event that any set of facts or circumstances may give a Party or any member of the Purchaser Group or the Seller Group, as applicable, a claim to indemnification or defense under both this Agreement and the Class A Purchase Agreement, such Party shall be required to concurrently seek indemnification or defense under the Class A Purchase Agreement for such claim, and to exhaust all remedies thereunder in connection with such claims or right of defense. In the

event that any member of the Purchaser Group or the Seller Group, as applicable, receives funds or proceeds from Concho or any insurance carrier or any other Third Party with respect to any Damages, Purchaser or Seller, as applicable, shall, regardless of when received by such member of the Purchaser Group or the Seller Group, as applicable, promptly pay and reimburse the other Party such funds or proceeds to the extent of any funds previously paid to any member of the Purchaser Group or the Seller Group, as applicable, with respect to such Damages, less all costs of pursuing such claim; provided, in no case shall Seller be entitled to any proceeds Purchaser recovers from Concho with respect to Damages in respect of a breach of a Company-Specific Representation.

(d)    Each Indemnified Person shall make reasonable efforts to mitigate or minimize all Damages upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Damages that are indemnifiable hereunder. If an Indemnified Person fails to so mitigate any indemnifiable Damages under the preceding sentence, the Indemnifying Party shall have no liability for the portion of such Damages that reasonably could have been avoided, reduced or mitigated had the Indemnified Person made such reasonable efforts.

(e)    The Parties shall treat, for U.S. federal and applicable state and local income Tax purposes, any amounts paid or received under this Article 12 as an adjustment to the Purchase Price, unless otherwise required by applicable Laws.

(f)    Notwithstanding anything to the contrary contained in this Agreement, under no circumstances shall any Party be entitled to double recovery under this Agreement, and to the extent a Party is compensated for a matter through an adjustment to the Purchase Price or third party recovery or insurance recovery (including from Concho under the Class A Purchase Agreement or any other agreements) actually received, such Party shall not have a separate right to indemnification hereunder for such matter.

(g)    To the extent of the indemnification obligations in this Agreement, Purchaser and Seller hereby waive for themselves and their respective successors and assigns, including any insurers, any rights to subrogation for Damages for which such Party is liable or against which such Party indemnifies any other Person under this Agreement. If required by applicable insurance policies, each Party shall obtain a waiver of such subrogation from its insurers.

Section 12.5    Indemnification Actions. All claims for indemnification under Article 12 shall be asserted and resolved as follows:

(a)    For purposes of this Article 12, the term “Indemnifying Party” when used in connection with particular Damages means (i) Seller in the event any member of the Purchaser Group is entitled to indemnity under this Agreement and (ii) Purchaser in the event any member of

the Seller Group is entitled to indemnification under this Agreement. For purposes of this Article 12, the term “Indemnified Person” when used in connection with particular Damages means (A) Purchaser in the event any member of the Purchaser Group is entitled to indemnity under this Agreement and (B) Seller in the event any member of the Seller Group is entitled to indemnification under this Agreement.

(b)    To make a claim for indemnification, defense or reimbursement under this Article 12, an Indemnified Person shall notify the Indemnifying Party of its claim, including the specific details (including supporting documentation of the alleged Damages and such Indemnified Person’s good faith estimate of the applicable claim) of and specific basis under this Agreement for its claim (the “Claim Notice”).

(c)    In the event that any claim for indemnification set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “Third Party Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Person to give notice of any Third Party Claim as provided in this Section 12.5 shall not relieve the Indemnifying Party of its obligations under this Article 12 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was allegedly inaccurate or breached.

(d)    In the case of a claim for indemnification based upon any Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies (i) in the case of Seller, Purchaser’s right to indemnification or defense from Seller in respect of such Third Party Claim as provided in this Article 12 or (ii) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Party admits or denies (A) in the case of Seller, Purchaser’s right to indemnification or defense from Seller in respect of such Third Party Claim as provided in this Article 12 or (B) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, then until such date as the Indemnifying Party admits or it is finally determined by a non-appealable judgment that such right or obligation exists, the Indemnified Person may file any motion, answer or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or adversely impacted by any such actions.

(e)    If (x) Seller admits Purchaser’s right to indemnification or defense from Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, as applicable, then the applicable Indemnifying Party shall have (i) the right and obligation to

diligently prosecute and control the defense of such Third Party Claim, at the sole cost and expense of Purchaser if Purchaser is the Indemnifying Party and at the sole cost and expense of Seller if Seller is the Indemnifying Party and (ii) have full control of such defense and proceedings, including any compromise or settlement thereof, unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnified Person or pertains to Taxes, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.5(e) provided that the Indemnified Person may file initial pleadings as described in the last sentence of subsection (d) above if required by court or procedural rules to do so within the thirty (30) day period in subsection (d) above. An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third Party Claim), (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity) or (C) pertains to Taxes.

(f)    If (x) Seller does not admit Purchaser’s right to indemnification or defense from Seller in respect of such Third Party Claim as provided in this Article 12 or admits such right but thereafter fails to diligently defend or settle the Third Party Claim or (y) Purchaser does not admit Seller’s right to indemnification or defense in respect of such Third Party Claim as provided in this Article 12 or admits its obligation but thereafter fails to diligently defend or settle the Third Party Claim, as applicable, then the Indemnified Person shall have the right, but not the obligation, to defend and control the defense against the Third Party Claim (at the sole cost and expense of the Indemnifying Party if Purchaser is the Indemnifying Party or at the sole cost and expense of Seller if Seller is the Indemnifying Party, and in either case if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of (x) Seller as the Indemnifying Party to admit Purchaser’s right to indemnity and reimbursement right against Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser as the Indemnifying Party to admit its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, as applicable, at any time prior to settlement or final determination thereof. If (x) Seller has not yet admitted Purchaser’s right to indemnity and reimbursement right against Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser has not yet admitted its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, as applicable, the Indemnified Person shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) (x) in the case of Seller, admit Purchaser’s right to indemnity and reimbursement right against Seller in respect of such Third Party Claim as provided in this Article 12 or (y) in the case of Purchaser, admit its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, as applicable, and (ii) if such right or obligation is so admitted, assume the defense of the Third Party Claim, including

the power to reject the proposed settlement. If the Indemnified Person settles any Third Party Claim over the objection of the Indemnifying Party after the Indemnifying Party has timely admitted such right or obligation for indemnification in writing and assumed the defense of the Third Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third Party Claim.

(g)    If both Seller and Concho admit that they are obligated to indemnify and defend an Indemnified Person against a Third Party Claim and Concho desires to control such defense or settlement of such Third Party Claim, then Seller agrees and acknowledges that Concho shall be entitled to control such defense or settlement on behalf of Seller and Concho and the cost and expense of such defense shall be borne equally by Seller and Concho. Notwithstanding the foregoing, in no event shall Seller agree, settle, compromise or enter into any agreement with any member of the Purchaser Group or any Third Party with respect to any claim for indemnification, defense or reimbursement under this Article 12 by any member of the Purchaser Group or by any Third Party without the prior written consent of Concho. Seller and Purchaser acknowledge and agree that any settlement or compromise with respect to any claim for indemnification, defense or reimbursement under this Article 12 by any member of the Purchaser Group or any Third Party entered into without the prior written consent of Concho shall be null and void ab initio.

(h)    Seller agrees that, in the event Purchaser brings suit against Concho for any claim, cause of action or dispute arising out of or relating to the Class A Purchase Agreement, including any claim for indemnification pursuant to Article 12 of the Class A Purchase Agreement, Seller consents to jurisdiction in the same court and lawsuit and waives any objection it may have to suit on the basis of lack of personal jurisdiction, improper venue or forum non conveniens.

(i)    In the case of a claim for indemnification not based upon a Third Party Claim (a “Direct Claim”), such Direct Claim shall be asserted by giving the Indemnifying Party reasonably prompt Claim Notice thereof prior to the termination of the applicable survival period. Such Claim Notice by the Indemnified Person shall describe the Direct Claim in reasonable detail, shall include copies of all available material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Person. The Indemnifying Party shall have sixty (60) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) (A) in the case of Seller, admit Purchaser’s right to indemnity and reimbursement right against Seller in respect of such Direct Claim as provided in this Article 12 or (B) in the case of Purchaser, admit its obligation to indemnify the Indemnified Person with respect to such Direct Claim under this Article 12, as applicable or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Person within such sixty (60) day period that it has cured the Damages or that it disputes the claim for such Damages, the Indemnifying Party shall be conclusively deemed (A) in the case of Seller, to have admitted Purchaser’s right to indemnity and reimbursement right against Seller in respect of such Direct Claim as provided in this Article 12 or (B) in the case of Purchaser, to have admitted its obligation to indemnify the Indemnified Person with respect to such Direct Claim under this Article 12, as applicable.

Section 12.6    Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, BOTH PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS ARTICLE 12 AND ELSEWHERE IN THIS AGREEMENT COMPLY WITH THE REQUIREMENT, KNOWN AS THE EXPRESS NEGLIGENCE RULE, TO EXPRESSLY STATE IN A CONSPICUOUS MANNER TO AFFORD FAIR AND ADEQUATE NOTICE THAT THIS AGREEMENT HAS PROVISIONS REQUIRING PURCHASER TO BE RESPONSIBLE FOR THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY OR OTHER FAULT OF MEMBERS OF THE SELLER GROUP. PURCHASER REPRESENTS TO THE SELLER GROUP (A) THAT PURCHASER HAS CONSULTED AN ATTORNEY CONCERNING THIS AGREEMENT OR, IF IT HAS NOT CONSULTED AN ATTORNEY, THAT PURCHASER WAS PROVIDED THE OPPORTUNITY AND HAD THE ABILITY TO SO CONSULT, BUT MADE AN INFORMED DECISION NOT TO DO SO AND (B) THAT PURCHASER FULLY UNDERSTANDS ITS OBLIGATIONS UNDER THIS AGREEMENT.

Section 12.7    Holdback Amount.

(a)    Notwithstanding anything herein to the contrary, the rights of each member of the Purchaser Group to indemnification (and Seller’s obligations) under Article 12 (as limited by the terms hereof) shall be satisfied first (i) from the Holdback Amount until the balance of the Holdback Amount equals zero dollars ($0.00) and only then, second (ii) by the Seller, it being agreed that any payment Seller is obligated to make to any member of the Purchaser Group pursuant to Article 12 shall be funded, to the extent available, by the Holdback Amount promptly after Seller’s receipt of the claim for indemnification or, if any Dispute regarding such claim exists, the final determination of the merits and amount of such claim in accordance with this Agreement.

(b)    No later than the fifth (5^th) Business Day after the Holdback Release Date, Seller and Purchaser shall execute and deliver to the Escrow Agent joint written instructions instructing the Escrow Agent to disburse to Seller from the Holdback Amount an amount equal to the positive remainder, if any, of (i) the Holdback Amount, minus (ii) the total amount of all claims for indemnity for Damages timely asserted by Purchaser under Section 12.2 that have not previously been resolved, settled, paid, agreed upon or satisfied prior to the Holdback Release Date and that Purchaser has notified Seller of prior to the Holdback Release Date (the “Pending Claims”).

(c)    Upon (or in connection with) the final settlement or non-appealable resolution after the Holdback Release Date of any Pending Claims, no later than the fifth (5^th) Business Day after the date of such settlement or resolution, Seller and Purchaser shall execute and deliver to the Escrow Agent joint written instructions instructing the Escrow Agent to disburse from the Holdback Amount first, to Purchaser the amount payable to Purchaser Group pursuant to such settlement or final resolution with respect to such settled or resolved claim for indemnity under Section 12.2 and second, to Seller an amount equal to the positive remainder, if any, of (A) the Holdback Amount (as determined immediately after giving effect to the disbursement described in subpart (i) above) minus (B) the aggregate amount of all remaining and unresolved Pending Claims.

(d)    No later than the fifth (5^th) Business Day after the date of the final settlement or non-appealable resolution after the Holdback Release Date of all Pending Claims and disbursement of all amounts to be disbursed by the Escrow Agent pursuant to this Section 12.7, Seller and Purchaser shall execute and deliver to the Escrow Agent joint written instructions instructing the Escrow Agent to disburse the entirety of the Holdback Amount, if any, to Seller.

(e)    All payments made or to be made under this Agreement to Seller shall be made by electronic transfer of immediately available funds to such bank and account as may be specified by Seller in writing. All payments made or to be made hereunder to Purchaser shall be by electronic transfer of immediately available funds to such bank and account as may be specified by Purchaser in writing.

Section 13.2    Governing Law.

All Disputes between the Parties to this Agreement and the transactions contemplated hereby shall have exclusive jurisdiction and venue only in the courts of the State of Texas in and for Midland County, Texas or the United States District Court located in Midland, Texas. Each Party waives any objection which it may have pertaining to improper

venue or forum non-conveniens to the conduct of any litigation or proceeding in the foregoing courts. Each Party agrees that any and all process directed to it in any such proceeding or litigation may be served upon it outside of the State of Texas in and for Midland County, Texas or the United States District Court located in Midland, Texas with the same force and effect as if such service had been made within the State of Texas in and for Midland County, Texas or the United States District Court located in Midland, Texas.

(b)    EACH OF THE PARTIES HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY LITIGATION, ACTION OR OTHER PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT.

(c)    The Parties agree that a dispute under this Agreement may raise issues that are common with one or more of the other Transaction Documents, under the Class A Purchase Agreement or documents executed or delivered thereunder or which are substantially the same or interdependent and interrelated or connected with issues raised in a related dispute, controversy or claim between or among the Parties, Concho or any of their respective Affiliates. Accordingly, any Party to a new Dispute under this Agreement or under the Class B Purchase Agreement may elect in writing within thirty (30) days after the filing or service of a new Dispute, or the amendment of a complaint, third-party complaint, answer and/or counterclaim to refer such Dispute for resolution by the applicable court together with any existing Dispute arising under this Agreement, other Transaction Documents or other documents executed by the Parties in connection herewith, under the Class A Purchase Agreement or documents executed or delivered thereunder, or which are substantially the same or interdependent and interrelated or connected. Nothing in this provision shall be construed to heighten or modify the standard of permissible and/or mandatory joinder or other third party practice under any applicable rules of procedure, statute or practice.

Section 13.4    Headings and Construction. The headings and captions herein are inserted for convenience of reference only and are not intended to govern, limit or aid in the construction of any term or provision hereof. The rights and obligations of each Party shall be determined pursuant to this Agreement. Seller and Purchaser have each had the opportunity to exercise business discretion in relation to the negotiation of the details and terms of the transaction contemplated hereby. This Agreement is the result of arm’s length negotiations from equal bargaining positions. It is the intention of the Parties that every covenant, term and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any Party (notwithstanding any rule of Law requiring an agreement to be strictly construed against the drafting Party) and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision thereof, it being understood that the Parties to this Agreement are sophisticated and have had adequate opportunity and means to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby and retain counsel to represent their interests and to otherwise negotiate the provisions of this Agreement.

Section 13.5    Waivers. Any failure by any Party to comply with any of its obligations, agreements or conditions herein contained may be waived by the Party to whom such compliance is owed by the application of the express terms hereof by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner. No course of dealing on the part of any Party or its respective officers, employees, agents or representatives and no failure by any Party to exercise any of its rights under this Agreement shall, in each case, operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. Except as otherwise expressly provided herein, no waiver of, or consent to a change in or modification of, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in or modification of, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided herein. The rights of each Party under this Agreement shall be cumulative and the exercise or partial exercise of any such right shall not preclude the exercise by such Party of any other right.

Section 13.6    Severability. It is the intent of the Parties that the provisions contained in this Agreement shall be severable and should any terms or provisions, in whole or in part, be held invalid, illegal or incapable of being enforced as a matter of Law, such holding shall not affect the other portions of this Agreement, and such portions that are not invalid shall be given effect without the invalid portion. Upon such determination that any term or provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 13.7    Assignment. No Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be null and void; provided, however, that (a) in the event of a Person succeeding to all or substantially all of the assets of Seller (whether by merger, consolidation, sale of assets or otherwise in a manner permitted by this Agreement), assignment or transfer of all or any part of this Agreement shall not require the prior written consent of Purchaser, (b) in the event that Concho makes any payment to any members of the Purchaser Group pursuant to the terms of the Limited Guarantee (as defined in the Class A Purchase Agreement), Purchaser shall, and cause such members of the Purchaser Group, to assign, transfer and subrogate to Concho any and all rights under Section 12.2 of this Agreement to the extent arising out of or related to the Damages for which such payment was made by Concho under the Limited Guarantee or (c) Purchaser’s assignment or transfer of all, but not less than all, of this Agreement to a wholly owned subsidiary that has executed and delivered to Purchaser a ratification and joinder of this Agreement that is reasonably acceptable to Seller shall not require the prior written consent of Seller (provided, however, such assignment shall not relieve or release Purchaser from the performance of Purchaser’s or its permitted assigns duties or obligations hereunder and each of Purchaser and such permitted assigns shall be fully and jointly and severally liable to Seller for the performance of all such duties and obligations of Purchaser hereunder). Unless expressly agreed to in writing by the Parties, no permitted assignment of any Party’s rights or duties shall relieve or release the assigning Party from the performance of such Party’s rights or obligations hereunder and such assigning Party shall be fully liable to the other Party for the performance of all such rights and duties. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns.

Section 13.8    Entire Agreement. This Agreement and the other Transaction Documents constitute the entire agreement between the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND THE TERMS AND PROVISIONS OF ANY SCHEDULE OR EXHIBIT HERETO, THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL GOVERN AND CONTROL; PROVIDED, HOWEVER, THAT THE INCLUSION IN ANY OF THE SCHEDULES AND EXHIBITS HERETO OF TERMS AND PROVISIONS NOT ADDRESSED IN THIS AGREEMENT SHALL NOT BE DEEMED A CONFLICT, AND ALL SUCH ADDITIONAL PROVISIONS SHALL BE GIVEN FULL FORCE AND EFFECT, SUBJECT TO THE PROVISIONS OF THIS SECTION 13.8.

Section 13.9    Amendment. This Agreement may be amended or modified only by an agreement in writing signed by Seller and Purchaser and expressly identified as an amendment or modification; provided, however, in no event shall this Agreement be amended without the prior written consent of Concho and any such amendment or modification without such prior written consent shall be null and void.

Section 13.10    No Third-Person Beneficiaries. Nothing in this Agreement shall entitle any Person other than Purchaser and Seller to any claim, cause of action, remedy or right of any kind, except for (a) the rights expressly provided to the Persons described in Section 7.1, Section 7.8 and Article 12, in each case, only to the extent such rights are exercised or pursued, if at all, by Seller or Purchaser acting on behalf of such Person (which rights may be exercised in the sole discretion of the applicable Party hereunder) and (b) Concho, which is expressly a beneficiary of Purchaser’s rights hereunder against Seller prior to Closing, which rights Concho may enforce against Seller prior to Closing upon prior written notice to Purchaser. Notwithstanding the foregoing: (i) the Parties reserve the right to amend, modify, terminate, supplement or waive any provision of this Agreement or this entire Agreement without the consent or approval of any other Person (including any Indemnified Person) other than Concho pursuant to Section 13.9 and (ii) no Party hereunder shall have any direct liability to any permitted Third Party beneficiary, nor shall any permitted Third Party beneficiary have any right to exercise any rights hereunder for such Third Party beneficiary’s benefit except to the extent such rights are brought, exercised and administered by a Party hereto in accordance with Section 12.4(b).

Section 13.11    Limitation on Damages. Except as set forth on Schedule 13.11, but notwithstanding anything else to the contrary contained in this Agreement, NO PERSON SHALL BE ENTITLED TO LOST PROFITS OR LOSS OF BUSINESS OPPORTUNITY, CONSEQUENTIAL DAMAGES, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY AND EACH OF PURCHASER AND SELLER, FOR ITSELF AND ON BEHALF OF THEIR RESPECTIVE MEMBERS OF THE PURCHASER GROUP AND SELLER GROUP, RESPECTIVELY, HEREBY EXPRESSLY WAIVES ANY RIGHT TO LOST PROFITS, LOSS OF BUSINESS OPPORTUNITY, CONSEQUENTIAL DAMAGES, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY; provided, however, that Seller and Purchaser agree that such limitation and waiver shall not apply to any such

Damages suffered by any Third Party for which responsibility is allocated among the Parties under the terms hereof.

Section 13.12    Deceptive Trade Practices Act. Purchaser certifies that it is not a “consumer” within the meaning of the Texas Deceptive Trade Practices Consumer Protection Act, Subchapter E of Chapter 17, Sections 17.41, et seq., of the Texas Business and Commerce Code, (as amended, the “DTPA”). Purchaser covenants, for itself and for and on behalf of any successor or assignee, that if the DTPA is applicable to this Agreement, (a) Purchaser is a “business consumer” as that term is defined in the DTPA, (b) AFTER CONSULTATION WITH ATTORNEYS OF PURCHASER’S OWN SELECTION, PURCHASER HEREBY VOLUNTARILY WAIVES AND RELEASES ALL OF PURCHASER’S RIGHTS AND REMEDIES UNDER THE DTPA AS APPLICABLE TO SELLER AND SELLER’S SUCCESSORS AND ASSIGNS AND (c) PURCHASER SHALL DEFEND AND INDEMNIFY THE SELLER GROUP FROM AND AGAINST ANY AND ALL CLAIMS OF OR BY ANY MEMBER OF THE PURCHASER GROUP OR ANY OF THEIR SUCCESSORS AND ASSIGNS OR ANY OF ITS OR THEIR AFFILIATES BASED IN WHOLE OR IN PART ON THE DTPA ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT.

Section 13.13    Time of the Essence; Calculation of Time. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date that is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day that is a Business Day.

Section 13.14    Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile, .pdf or other electronic transmission of copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof.

IN WITNESS WHEREOF, this Agreement has been executed by each of the Parties effective as of the Execution Date.

Neither these Schedules nor any disclosure made in or by virtue of them constitutes or implies any representation, warranty or covenant by Seller not expressly set out in the Agreement, and neither these Schedules nor any such disclosure has the effect of, or may be construed as, adding to, broadening, deleting from or revising the scope of any of the representations, warranties or covenants of Seller in the Agreement. Any item or matter disclosed or listed on any particular Schedule, other than Schedule 7.15, is deemed to be disclosed or listed on any other Schedules to the extent it is reasonably apparent on its face that such item relates or is applicable to, or is properly disclosed under, such other Schedule or the section of the Agreement to which such other Schedule corresponds, notwithstanding the fact that the Schedules are arranged to correspond to the sections of the Agreement, that a particular section of the Agreement makes reference to a particular Schedule, or that a particular representation, warranty or covenant in the Agreement may not make reference to a Schedule. Matters reflected in these Schedules are not necessarily limited to matters required by the Agreement to be reflected in these Schedules. The fact that any item of information is contained herein is not an admission of liability under any applicable Law, and does not mean that such information is required to be disclosed in or by the Agreement, or that such information is material, but rather is intended only to qualify the representations, warranties and covenants in the Agreement and to set forth other information required by the Agreement. Except to the extent the Agreement specifically contemplates disclosing items on a Schedule that are material (or other words or phrases to that effect) or that meet a certain dollar threshold, neither the specification of any dollar amount in any representation, warranty or covenant contained in the Agreement nor the inclusion of any specific item in these Schedules is intended to imply that such amount, or a higher or lower amount, or the item so included, or any other item, is or is not material, except as aforesaid, and no Person shall use the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between or among the parties to the Agreement as to whether any obligation, item or matter not described herein or included in these Schedules is or is not material for purposes of the Agreement. The information set forth on the Schedules shall not be used as a basis for interpreting the terms “material,” “materially,” “materiality,” “Material Adverse Effect” or any similar qualification in the Agreement. Neither the specification of any item or matter in any representation, warranty or covenant contained in the Agreement nor the inclusion of any specific item in these Schedules is intended to imply that such item or matter, or another item or matter, is or is not in the ordinary course of business, and no Person shall use the setting forth or the inclusion of any such item or matter in any dispute or controversy between or among the parties to the Agreement as to whether any obligation, item or matter described or not described herein or included or not included in these Schedules is or is not in the ordinary course of business for purposes of the Agreement. Notwithstanding anything herein or in the Agreement to the contrary, no disclosure set forth in Schedule 7.15 shall be deemed to apply or be disclosed other than with respect to the covenant set forth in Section 7.15.

Headings and references to the VDR have been inserted in these Schedules for reference only and do not amend or supplement the descriptions of the disclosed items set forth in the Agreement. Where a reference is made to a section or exhibit, such reference shall be to a section of or exhibit to the Agreement unless otherwise indicated. Whenever the words “include,” “includes,” or

“including” are used in these Schedules, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import.
