Seller understands that none of the Buyer Stock Consideration will have been registered pursuant to the Securities Act or any applicable state securities Laws, that the Buyer Stock Consideration will be characterized as “restricted securities” under federal securities Laws, and that the Buyer Stock Consideration may not be sold or otherwise disposed of without registration under the Securities Act or an exemption therefrom.

In connection with the foregoing, Buyer may, at its option, but subject to Section 7.17, cause a Phase I environmental assessment of all or any portion of the Real Property to be conducted by a reputable environmental consulting or engineering firm (the “Environmental Consultant”) and such Environmental Consultant may conduct visual inspections, record reviews, and interviews relating to such Real Property, as applicable, including their condition and their compliance with Environmental Laws (collectively the “Phase I Assessment”).  Buyer’s right of access shall not, in any circumstance, entitle Buyer to conduct testing, sampling, boring, drilling or invasive activities or a Phase II environmental assessment or similar or more extensive assessment of all or any portion of the Real Property without the prior written consent of Seller and Pioneer, which consent shall not be unreasonably withheld, conditioned or delayed. Seller and Pioneer shall have the right to be present during the Phase I Assessment.  Buyer shall coordinate the Phase I Assessment with Seller and Pioneer to minimize any inconvenience to or interruption of the conduct of business by Seller and Pioneer.  Buyer shall abide by Seller’s, Pioneer’s, and any Third Party operator’s, safety rules, regulations and operating policies while conducting its due diligence evaluation of the Real Property, as applicable, including the Phase I Assessment.  The Phase I Assessment shall be conducted at the sole risk, cost and expense of Buyer, and all of Buyer’s and the Environmental Consultant’s activity conducted under this Section 7.4(a) shall be subject to the indemnity provisions of Section 7.4(b). All information or data obtained under this Section 7.4(a) shall be subject to the Confidentiality Agreement, and Buyer is prohibited from disclosing any such information or data to any Third Parties, including any Governmental Authority, without the prior written consent of Seller and Pioneer, which consent may be granted or withheld by Seller and Pioneer in their sole discretion.  Buyer will provide Seller and Pioneer a copy of any final reports, data and conclusions relating to the Phase I Assessment. Notwithstanding the foregoing, Buyer shall have no right of access to, and neither Seller nor Pioneer shall have any obligation to provide to Buyer, information relating to: (i) the identity of bidders and potential bidders and bids received from others in connection with the transactions contemplated by this Agreement (or similar transactions) and information and analyses (including financial analyses) relating to such bids; (ii) any information, the disclosure of which would, in Seller’s and Pioneer’s good faith opinion following consultation with outside counsel, jeopardize any legal privilege against disclosure available to Seller, Pioneer or any of their respective Affiliates relating to such information or would cause Seller, Pioneer or any of their respective Affiliates to breach a confidentiality obligation arising under any contract;  (iii) any information the

34

disclosure of which would result in a violation of Law; or (iv) the Income Tax Returns of Seller, Pioneer or any of their Affiliates. All requests for information made under this Section 7.4(a) shall be directed to the Person designated in writing by Seller or Pioneer, respectively, and all such information provided shall be subject to the Confidentiality Agreement.

(b)                                 Indemnity.  Buyer shall indemnify the Seller Indemnified Parties, any contractors and their respective Representatives from and against Losses arising out of an act or omission by Buyer or its authorized Representatives during any site visits, inspections or Phase I Assessment by Buyer and its Representatives under Section 7.4(a); provided that this indemnity shall not, in whole or in part, apply to any Losses which arise as a result of a pre-existing condition.

7.5                               Books and Records.  From and after the Closing, Seller and Pioneer may retain copies of any or all of the Records and Buyer will (i) give Seller, Pioneer and their authorized Representatives reasonable access to all Records, personnel, accountants, offices and other facilities and properties of or relating to the Assets, (ii) permit Seller and Pioneer to make and retain such copies and inspections thereof as Seller or Pioneer may reasonably request, and (iii) furnish Seller and Pioneer with such financial and operating data and other information with respect to the performance of the Seller Services as Seller or Pioneer may from time to time reasonably request, in each case (A) to comply with reporting, disclosure, filing or other requirements imposed on Seller, Pioneer or their Affiliates (including under applicable securities laws) by a Governmental Authority having jurisdiction over Seller, Pioneer or their Affiliates, (B) for use in any Proceeding or in order to satisfy audit, accounting, claims, regulatory, litigation, subpoena or other similar requirements or (C) to comply with the obligations of Seller and Pioneer under the Transaction Documents; provided, however, that in the event that Buyer determines that any such provision of access or information could violate any Law or Material Contract, or waive any attorney-client privilege, the Parties shall take all reasonable measures to permit the compliance with such obligations in a manner that avoids any such harm or consequence. For a period of six (6) years following the Closing Date, the Buyer will not, and will cause its Affiliates not to, without first having offered to deliver the same to Seller and Pioneer, destroy or permit the destruction of any of books and records relating to the Assets in such Buyer’s or its Affiliate’s possession. This Section 7.5 shall not apply to Tax matters, which shall be governed by Article 8.

7.6                               Pioneer Marks.  Buyer acknowledges and agrees that it obtains no right, title, interest, license or any other right whatsoever to use the Pioneer Marks. Buyer shall, as promptly as practicable, but in any case within ninety (90) days after the Closing, eliminate the Pioneer Marks from the Assets acquired pursuant to this Agreement, including signage, and provide written verification thereof to Seller and Pioneer promptly after completing such removal and change. Buyer shall not do any business or offer any goods or services under the Pioneer Marks. Buyer shall not send, or cause to be sent, any correspondence or other materials to any Person on any stationery that contains any Pioneer Marks which would or might reasonably be expected to confuse any Person into believing that Buyer has any right, title, interest or license to use the Pioneer Marks.

7.11                        Consents.

(a)                                 As promptly as practicable after the Execution Date, Seller shall deliver notice letters to all Persons identified on Schedule 4.18 in connection with the transactions contemplated hereby. Prior to the Closing, Buyer shall notify Seller of any Person that Buyer in good faith believes should have been identified on Schedule 4.18 upon execution of this Agreement and, prior to the Closing Seller shall deliver notice letters to any such Person or any

36

other Person that Seller determines should have been included on Schedule 4.18 upon execution of this Agreement. Seller shall promptly notify Buyer when Seller delivers any such notice letter to any Person.

(b)                                 Prior to the Closing, with respect to each Material Contract that is subject to a consent identified on Schedule 4.18, including any Hard Consent that is not set forth on Schedule 4.18 as of the Execution Date but is discovered by either Party or added to Schedule 4.18 after the Execution Date and prior to the Closing Date (each, a “Required Consent Contract”), Seller shall use Reasonable Efforts to obtain such Hard Consent to the assignment to Buyer of all of Seller’s right, title and interest in and to such Required Consent Contract.  Not later than five (5) Business Days prior to the Closing, Seller shall notify Buyer in writing of any Required Consent Contracts for which the Hard Consent to assign has not been obtained.

(c)                                  If (i) Seller fails to obtain a Hard Consent prior to Closing or (ii) a Hard Consent requested by Seller is denied in writing, then, in each case such Required Consent Contracts shall not be assigned to Buyer at Closing, there shall be no adjustment to the Purchase Price, and such Required Consent Contract shall be assigned, in whole or in part, by Seller to Buyer after the Closing in accordance with the provisions of Sections 7.11(d) and 7.11(e) (each, a “Post-Closing Assigned Contract”).  All Required Consent Contracts other than the Post-Closing Assigned Contracts (each, a “Closing Assigned Contract”) shall be assigned, in whole or in part, by Seller to Buyer at Closing.  Notwithstanding the date on which all of Seller’s right, title and interest in and to any Closing Assigned Contract or Post-Closing Assigned Contract is assigned by Seller to Buyer, each Closing Assigned Contract and Post-Closing Assigned Contract shall constitute an Asset for all purposes of this Agreement and the other Transaction Documents.

(d)                                 Following the Closing, Seller shall use, and shall cause their respective Affiliates to use, Reasonable Efforts to obtain the Hard Consent to the assignment, in whole or in part, of each Post-Closing Assigned Contract to Buyer.  Seller shall assign to Buyer all of its right, title and interest in and to such Post-Closing Assigned Contract within five (5) Business Days following receipt of the applicable Hard Consent to such assignment.  Any such assignment of a Post-Closing Assigned Contract that constitutes a Material Contract shall be effected by the execution by Seller a contract assignment with respect to such Post-Closing Assigned Contract.

37

when such Post-Closing Assigned Contract is assigned to Buyer, and (ii) Buyer shall be responsible for performing, and Buyer (or Seller acting at Buyer’s direction and cost) shall perform, all obligations of Buyer with respect to such Post-Closing Assigned Contract that would have been applicable to Buyer had Seller’s right, title and interest therein been directly assigned to, and assumed by, Buyer.

7.12                        Insurance.  From and after the Closing, neither Seller nor any of its Affiliates shall have any obligation of any kind to maintain any form of insurance covering all or any part of the performance of the Seller Services or the Continuing Employees and Buyer shall be responsible for securing all insurance it considers appropriate for the performance of the Seller Services.  Buyer further covenants and agrees not to seek to assert or to exercise any rights or claims relating to the performance of the Seller Services under or in respect of any past or current insurance policy of Seller or any of its Affiliates under which the performance of the Seller Services was covered or the Assets are insured.

7.13                        Accounts Payable.  Except for the Assumed Obligations, the Parties acknowledge that Buyer shall not assume any Accounts Payable of Seller or its Affiliates as of the Closing.  Seller covenants to pay and discharge the valid Accounts Payable obligations of Seller relating to the Assets and the performance of the Seller Services as of the Closing that are not included in the Assumed Obligations after the Closing, in accordance with the Seller’s past payment practices and applicable Law.

7.14                        Confidentiality.

(a)                                 The terms of the Confidentiality Agreement are hereby incorporated by reference, and the Confidentiality Agreement shall continue in full force and effect in accordance with its terms until the Closing, at which time the Confidentiality Agreement shall terminate.  If this Agreement is, for any reason, terminated prior to the Closing, the Confidentiality Agreement shall continue in full force and effect in accordance with its terms. Nothing provided to Buyer or its Affiliates or its or their respective Representatives pursuant to Section 7.4(a) shall in any way amend or diminish Buyer’s obligations under the Confidentiality Agreement.  Buyer acknowledges and agrees that all Proprietary Information (as defined in the Confidentiality Agreement) provided to Buyer or its Affiliates or its or their respective Representatives pursuant to Section 7.4(a) or otherwise by Seller or any of its Affiliates or any of their respective Representatives shall be subject to the terms and conditions of the Confidentiality Agreement and the remainder of this Section 7.14.

(b)                                 If the Closing occurs, Seller shall maintain in confidence, shall cause its Affiliates to maintain in confidence, and shall use Reasonable Efforts to cause its (and its Affiliates’) Representatives to maintain in confidence, any written, oral or other information relating to Buyer from and after the Closing until the second (2nd) anniversary of the Closing Date, except that (i) the requirements of this Section 7.14(b) shall not apply to the extent that (A) any such information is or becomes generally available to the public other than as a result of disclosure by Seller or its Affiliates or any of its or their respective Representatives in violation of the Confidentiality Agreement or this Section 7.14(b), (B) any such information is required by applicable Law or a Governmental Authority to be disclosed (including any report, statement, testimony or other submission to such Governmental Authority), (C) any such information is

(c)                                  If the Closing occurs, Buyer shall maintain in confidence, shall cause its Affiliates to maintain in confidence, and shall use Reasonable Efforts to cause its (and its Affiliates’) Representatives to maintain in confidence, any written, oral or other information relating to Seller and its Affiliates from and after the Closing until the second (2nd) anniversary of the Closing Date, except that (i) the requirements of this Section 7.14(c) shall not apply to the extent that (A) any such information is or becomes generally available to the public other than as a result of disclosure by Buyer or its Affiliates or any of its or their respective Representatives in violation of the Confidentiality Agreement or this Section 7.14(c), (B) any such information is required by applicable Law or a Governmental Authority to be disclosed (including any report, statement, testimony or other submission to such Governmental Authority), (C) any such information is reasonably necessary to be disclosed in connection with any Proceeding or in any dispute with respect to this Agreement (including in response to any summons, subpoena or other legal process or formal or informal investigative demand issued to the disclosing Party in the course of any Proceeding) or (D) any such information was or becomes available to Buyer or its Affiliates or its or their respective Representatives on a non-confidential basis and from a source (other than Seller or any of its Affiliates or any of their or their respective Representatives) that is not bound by a confidentiality agreement with respect to such information, and (ii) this Section 7.14(c) shall not prohibit disclosure of any such information to any Representatives of Buyer or its Affiliates (provided, however, that Buyer shall be responsible for any breach of the applicable terms of this Section 7.14(c) by any of such Representatives to which it disclosed such information) or to any Representatives of Buyer’s or its Affiliates’ current or prospective lenders or equity investors who are subject to a confidentiality obligation no less restrictive than this Section 7.14(c) with respect to such information.

7.15                        Ancillary Transaction Documents.  From the Execution Date to the Closing Date, Buyer, Seller and Pioneer shall negotiate in good faith to enter into (a) a ground lease agreement with the commercial terms specified on Schedule 7.15(a), (b) a transition services agreement with the commercial terms specified on Schedule 7.15(b), and (c) a surface access and use agreement with the commercial terms specified on Schedule 7.15(c); provided, however, that entry into all or any of the agreements contemplated by this Section 7.15 shall not be a condition to the Parties’ obligations to consummate the transactions contemplated by this Agreement.

Article 8
Tax Matters

8.1                               Purchase Price Allocation.

(a)                                 The Parties shall allocate the purchase price for the Assets (as determined for applicable U.S. federal Income Tax purposes) among the Assets in a manner consistent with Section 1060 of the Code and the Treasury Regulations thereunder (the “Allocation”) pursuant to the terms of this Section 8.1.

(b)                                 No later than sixty (60) days after the Closing Date, Buyer shall deliver to Pioneer a draft of the Allocation as determined by one or more independent appraisals conducted on behalf of Buyer, at Buyer’s sole cost and expense (the “Proposed Tax Allocation”).  Pioneer shall have thirty (30) days following its receipt of the Proposed Tax Allocation to review the Proposed Tax Allocation and, if Pioneer does not provide Buyer with a notice in writing of any objections to the Proposed Tax Allocation within such thirty (30) day period, the Proposed Tax Allocation shall be deemed agreed upon by the Parties (the “Agreed Tax Allocation”).  If Pioneer provides written notice of its objections within such thirty (30) day period, the Parties shall cooperate and negotiate in good faith to resolve any disputes relating to the Proposed Tax Allocation. If the Parties are unable to resolve their differences and mutually agree on the Proposed Tax Allocation, each Party shall be permitted to take an independent position with respect to the Allocation on its applicable Tax Returns (including IRS Form 8594) or in connection with any audit or other Proceeding, or otherwise.  If the Parties reach agreement with respect to such disputes within the thirty (30) day period following Buyer’s receipt of such written notice, the Proposed Tax Allocation, as finally agreed to by the Parties pursuant to this Section 8.1, shall become the Agreed Tax Allocation.  Pioneer and Buyer agree not to assert, and will cause their respective Affiliates not to assert, in connection with any audit or other Proceeding with respect to Taxes or in connection with the filing of any Tax Return (including IRS Form 8594), any asset values or other items in a manner inconsistent with the Agreed Tax Allocation, unless required to do so by applicable Law or a “determination” within the meaning of Section 1313(a)(1) of the Code; provided, however, that nothing contained herein shall prevent Buyer or Pioneer, nor any of their respective Affiliates, from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Agreed Tax Allocation and neither Buyer nor Pioneer, nor any of their respective Affiliates, shall be required to litigate before any court any proposed deficiency or adjustment by any Governmental Authority challenging any position based on or arising out of the Agreed Tax Allocation.

(c)                                  Each of Pioneer and Seller, on the one hand, and Buyer, on the other hand, shall promptly notify the other in writing upon receipt of notice of any pending or threatened Tax

40

audit, assessment or other Proceeding challenging any position based on or arising out of the Allocation.

(d)                                 Adjustments to the Purchase Price pursuant to this Agreement shall be allocated to the particular Asset to which such adjustment relates to the extent such adjustment relates to such Asset and to the extent that it is, in the commercially reasonable discretion of Pioneer, possible to do so.  Any adjustment to the Purchase Price not allocated to a specific Asset pursuant to the immediately preceding sentence shall be allocated among the various Assets on a pro rata basis in proportion to the unadjusted Purchase Price allocated to such Asset. Buyer will update the Allocation to reflect any adjustments described in this Section 8.1(c) and such adjustments shall become part of the Allocation for all purposes hereunder.

8.2                               Responsibility for Filing Tax Returns and Paying Taxes.

(a)                                 Subject to Section 8.2(b), through the end of the day prior to the Closing Date, Pioneer or Seller, as applicable, shall be responsible for preparing and timely filing all Tax Returns in respect of the Assets which are required to be filed before the Closing Date and for paying all Taxes due and owing with respect to such Tax Returns.

(b)                                 Buyer shall be responsible for preparing and timely filing all Tax Returns in respect of the Assets required to be filed on or after the Closing Date (including any Transfer Tax Returns required by applicable Law to be filed by Buyer) and paying the Taxes due and owing; provided, however, that in the event that Pioneer or Seller is required by applicable Law to file a Tax Return with respect to such Taxes (including any Transfer Tax Returns required by applicable Law to be filed by Pioneer or Seller) on or after the Closing Date, Buyer shall, following Pioneer’s request, promptly pay to Pioneer or Seller, as applicable, all such Taxes owed by Buyer pursuant to the provisions of Section 11.1(b)(iii) (as determined pursuant to Section 8.3).  Pioneer will provide a copy of any Tax Return prepared by Pioneer or Seller, as applicable, pursuant to this Section 8.2(b) (other than Income Tax Returns) to Buyer.  Any Tax Return prepared by Buyer pursuant to this Section 8.2(b) will be prepared in a manner consistent with past practice of Pioneer or Seller, as applicable, except as otherwise required by applicable Law.  Buyer shall provide to Pioneer, within fifteen (15) days prior to the due date for filing, all Tax Returns prepared by Buyer for which Pioneer or Seller, as applicable, would reasonably be expected to have an indemnification obligation under this Agreement, for Pioneer’s review and approval of Pioneer or Seller, respectively, not to be unreasonably withheld or delayed.

(c)                                  Not later than five (5) days prior to the due date for the payment of Taxes on any Tax Return which Buyer has the responsibility to cause to be filed pursuant to Section 8.2(b), Pioneer or Seller, as applicable, shall pay to Buyer the amount of Taxes owed by Pioneer or Seller, respectively, pursuant to the provisions of Section 11.1(a)(iii) (as determined pursuant to Section 8.3).  For the avoidance of doubt, (i) no payment obligation pursuant to this Section 8.2(c) shall excuse Pioneer or Seller from their indemnification obligations pursuant to Section 11.1(a)(iii) if the amount of Taxes, as ultimately determined on audit or otherwise, for the periods covered by such Tax Returns exceeds the amount of the payment under this Section 8.2(c) and (ii) no payment obligation pursuant to Section 8.2(a) and Section 8.2(b) shall excuse Buyer from its indemnification obligation pursuant to Section 11.1(b)(iii) if the amount of

41

Taxes, as ultimately determined on audit or otherwise, for periods covered by such Tax Returns exceeds the amount of Buyer’s payment for such period under Section 8.2(a) or Section 8.2(b).

8.3                               Straddle Period Tax Allocation.  Any liability attributable to a Straddle Period (i) in the case of real property, business personal property and other ad valorem Taxes, shall be apportioned between the portion of such period ending prior to the Closing Date and the portion beginning on or after the Closing Date by apportioning such Taxes on a per diem basis and (ii) in the case of all other Non-Income Taxes, shall be apportioned between the portion of such period ending at the end of the day prior to the Closing Date and the portion beginning on the Closing Date on a closing of the books basis, provided that exemptions, allowances or deductions that are calculated on an annual basis shall be apportioned on a per diem basis.

8.4                               Disputes.  The Parties shall act in good faith to resolve any disputes in respect of Section 8.2 prior to the date on which the relevant Tax Return is required to be filed. If the Parties cannot resolve any disputed item, the item in question shall be resolved by the Accounting Referee; provided, that, if any such Tax Return is required to be filed (taking into account validly obtained extensions) prior to the resolution of such dispute item, and Pioneer or Seller would reasonably be expected to have an indemnification obligation pursuant to the terms of this Agreement with respect to such Tax Return, such Tax Return shall be prepared and filed in a manner consistent with such indemnifying party’s position. Buyer, on the one hand, and Pioneer and Seller, as applicable, on the other hand, shall each provide the other with all information reasonably necessary to prepare any Tax Return relating to the Assets.

8.5                               Responsibility for Tax Audits and Contests.

(a)                                 After the Closing, Buyer shall notify Pioneer in writing within fifteen (15) days of the receipt of the notice of any proposed assessment or commencement of any Tax audit or administrative or judicial Proceeding and of any Tax demand or claim on Buyer or any of its Affiliates that could reasonably be expected to result in an indemnification obligation of Pioneer or Seller pursuant to the terms of this Agreement (a “Tax Claim”); provided that failure to timely provide such notice shall not affect the right of Buyer’s indemnification hereunder, except to the extent Pioneer or Seller is materially prejudiced by such delay or omission.  Such notice shall contain factual information describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any Governmental Authority in respect of any such asserted Tax liability.

(b)                                 Pioneer shall have the right to control any Proceeding with respect to any Tax Claim, provided that Pioneer shall (i) keep Buyer reasonably informed of the progress of such Proceeding, (ii) allow Buyer (or Buyer’s counsel) to be an observer in any meeting related to such Proceeding with the applicable Governmental Authority at its own cost and expense, and (iii) not settle, compromise and/or concede any portion of such Proceeding that would reasonably be expected to materially affect the Tax liability of Buyer with respect to the Assets for any taxable year (or portion thereof) beginning on or after the Closing Date without the consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed; provided, further, that, in the event Pioneer does not elect to control any such Proceeding, Buyer shall (i) keep Pioneer reasonably informed of the progress of such Proceeding, (ii) allow Pioneer (or Pioneer’s counsel) to be an observer in any meeting related to such Proceeding with the

42

applicable Governmental Authority at its own cost and expense, and (iii) not settle, compromise and/or concede any portion of such Proceeding without the consent of Pioneer, which consent shall not be unreasonably withheld, conditioned or delayed. Buyer and Pioneer shall each provide the other with all information reasonably necessary to conduct a Tax audit with respect to Taxes or the transactions contemplated by this Agreement.

8.6                               Cooperation on Tax Returns and Tax Proceedings.  Notwithstanding anything to the contrary in this Agreement, Buyer, Pioneer, and Seller shall use Reasonable Efforts to cooperate fully as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any Proceeding with respect to Taxes imposed on or with respect to the Assets.  Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

8.7                               Tax Refunds.  The Parties and their respective Affiliates shall reasonably cooperate with the other Party in connection with obtaining any refund of Taxes. If a Party receives a refund with respect to any Taxes for which the other Party is responsible under this Agreement, the Party receiving the refund shall pay to the other Party within ten (10) Business Days after such receipt the amount of such refund to which such other Party is entitled pursuant to the provisions herein.

8.8                               Transfer Taxes.  Buyer shall be liable for any state or local transfer, sales, use, stamp, registration or other similar Taxes resulting from the transactions contemplated by this Agreement (“Transfer Taxes”), including any costs and expense in connection with filing any necessary Tax Returns and other documentation with respect to all Transfer Taxes.  Buyer and Seller shall cooperate to file such Tax Returns and documentation, and if Pioneer or Seller is required by Law to pay or remit such Transfer Taxes, Buyer shall promptly reimburse Pioneer or Seller, as applicable, for such Transfer Taxes.  The Parties shall cooperate in establishing the applicability of any exemptions from Transfer Taxes. Notwithstanding anything to the contrary in this Agreement, the Parties shall cooperate in good faith and use their Reasonable Efforts (including, for the avoidance of doubt, by providing access to Tax Returns and any Retained Records or other relevant documentation) to minimize the amount of any Transfer Taxes and/or qualify for any applicable exemptions with respect to Transfer Taxes.

8.9                               Post-Closing Actions.

(a)                                 Buyer and Pioneer shall, and shall cause their Affiliates to, (i) either (x) retain all records with respect to Tax matters relating to any taxable period prior to the Closing Date until the day that is ninety (90) days after the expiration of the applicable statute of limitation, or (y) send such records described in (x) above to the other Party, and (ii) abide by all record retention agreements entered into with any Governmental Authority.

(b)                                 Buyer shall not, and shall cause its Affiliates to not, without duplication, (i) amend any Tax Return unless required by Law, (ii) initiate any voluntary disclosure, (iii) agree to extend or waive any statute of limitation, or (iv) take any Tax position on any Tax Return, in each case, with respect to Taxes relating to the Assets or the performance of the Seller

43

Services for any taxable period (or portion thereof) ending prior to the Closing Date, without prior written consent of Pioneer, which consent shall not be unreasonably withheld, conditioned or delayed.

Article 9
Employment Matters

9.1                               Seller Benefit Plans.  Effective as of the Closing Date (or the applicable Continuing Employee’s Hire Date, if later), the Continuing Employees (as defined in Section 9.4(a)) shall cease to accrue further benefits and shall cease to be active participants under the Business Employee Benefit Plans.  Buyer shall not assume any of the Seller Benefits Plans.  Seller and its ERISA Affiliates shall retain and shall be solely responsible for all Liabilities under the Seller Benefit Plans, and neither Buyer nor its Affiliates shall have any Liability or responsibility to or under the Seller Benefit Plans, whether such Liability or responsibility arose before, on or after the Closing Date.

9.2                               Pre-Closing Date Claims under Seller Benefit Plans.  To the extent that an Available Employee was a participant in a Business Employee Benefit Plan, the Business Employee Benefit Plans shall be responsible for providing welfare benefits (including medical, hospital, dental, accidental death and dismemberment, life, disability and other similar benefits) to all participating Available Employees (and all dependents, beneficiaries, designees and assignees thereof) for all claims incurred prior to the Hire Date under and subject to the terms and conditions of such plans.  For purposes of this Section 9.2, a claim is incurred with respect to (i) accidental death and dismemberment, disability, life and other similar benefits when the event giving rise to such claim occurred and (ii) medical, hospital, dental and other similar benefits when the services with respect to such claim are rendered.  Seller shall pay out, in accordance with Seller’s applicable policies in effect at that time, accrued and unused paid time off balances, as of the Hire Date, of the Continuing Employees within thirty (30) days of the Hire Date, provided that with respect to any Continuing Employee whose Hire Date is on or after January 1, 2019, such payment shall in all events be made during the 2019 calendar year.

9.3                               Offers to Available Employees.  No later than five (5) days after the Execution Date, Seller shall deliver to Buyer a list of those Business Employees, in a number not to exceed sixty (60) employees, whom Seller or any Pioneer Entity has elected to retain and to whom Buyer and its Affiliates will not make offers of employment in connection with the transactions contemplated by this Agreement (the “Excluded Employees”).  No later than five (5) days after the Execution Date, Seller shall deliver to Buyer a letter that includes a list of all Available Employees (the “Employee Letter”). The Employee Letter shall include the following data with respect to each Available Employee: (i) his or her name; (ii) his or her title or position; (iii) status as exempt or non-exempt under the Fair Labor Standards Act, as amended; (iv) primary location of employment; (v) start date or seniority date (as applicable); (vi) his or her hourly wage rate or annualized base salary, as applicable;  (vii) a description of all commission, bonus or other incentive-based compensation arrangements applicable to such employee, including, but not limited to, the target payment amount for the current year and paid in the current year as of the date hereof; (viii) the number of years of service credit under each Business Employee Benefit Plan; (ix) whether or not such employee is on an approved leave of absence; and (x) whether such person is full-time or part-time. No later than five (5) days after the Execution Date, Seller

44

shall deliver to Buyer a list of those Available Employees in a field engineer role, in a number not to exceed ten (10) employees, to whom Seller or any Pioneer Entity may make an offer to retain or employ and to whom Buyer or its Affiliates may make an offer of employment in connection with the transactions contemplated by this Agreement (the “Selective Employees”).  A Selective Employee shall have the opportunity to consider offers of employment, if any, from both a Pioneer Entity and Buyer or its Affiliates.  In the event a Selective Employee accepts an offer from a Pioneer Entity, after such acceptance, such employee shall be treated as an Excluded Employee for purposes of this Article 9.  Any Selective Employee who accepts an employment offer from Buyer or its Affiliates shall be a Continuing Employee as defined in this Article 9.  Seller shall, and shall cause all other Pioneer Entities to, (i) reasonably assist Buyer in communicating with the Available Employees regarding potential employment with Buyer and its Affiliates, (ii) permit Buyer and its Affiliates to interview Available Employees at reasonable times on Pioneer Entities’ premises or otherwise and (iii) not interfere with any negotiations by the Buyer or its Affiliates to employ any Available Employee or discourage any Available Employee from accepting employment with the Buyer or any of its Affiliates; provided that, any action by Seller or any Pioneer Entity to (i) make employment offers to or retain the Selective Employees or (ii) share information with Available Employees regarding severance benefits or otherwise respond to inquiries regarding termination of employment with Seller or any Pioneer entity shall not be deemed a violation of this Section. Nothing in this Article 9 shall affect the right of Seller and its Affiliates to terminate the employment of an Available Employee for any reason or at any time, which termination shall promptly be communicated to Buyer.  Seller shall update the Employee Letter if any material change in the information required to be included therein (including removal of or addition to the list of Available Employees) occurs, with such update to be made within two (2) Business Days after such change.

(b)                                 Buyer shall:

(i)                                     on or before December 7, 2018, make written offers of “at will” employment to those Available Employees whom Buyer selects in its sole discretion, in each case, such offers setting forth the Closing Date as the employment commencement date with respect to Available Employees who are not Inactive Available Employees, with such offers conditioned upon the Closing and providing such Available Employees at least five (5) Business Days from the date thereof to either accept or reject such offers.  Unless otherwise agreed to by the Transition Committee, Buyer agrees to make at least six hundred thirty (630) offers of employment pursuant to this Article 9;

(ii)                                  on or before December 17, 2018, Buyer shall notify Seller as to each Available Employee who has accepted employment with Buyer or any of its Affiliates as of the date of such notification, which acceptance may be conditioned upon the occurrence of the Closing and effective as of the Closing Date with respect to Available Employees who are not Inactive Available Employees, and each Available Employee who has rejected Buyer’s offer of employment as of the date of such notification;

(iii)                               indemnify and hold harmless Seller and its Affiliates with respect to all claims by Available Employees and Liabilities with respect thereto, in all

45

cases, for violations of applicable Laws by Buyer or its Affiliates relating to or arising out of Buyer’s or its Affiliates’ employment evaluation, selection and offer process regarding Available Employees and conducted in connection with the transactions contemplated by this Agreement;

(c)                                  Except as otherwise expressly set forth in this Article 9, nothing in this Agreement shall be deemed to prevent or restrict in any way the right of Buyer or its Affiliates terminate, reassign, promote or demote any of the Continuing Employees after the Closing or to change adversely or favorably the title, powers, duties, responsibilities, functions, locations, salaries, other compensation or terms or conditions of employment of such employees.

9.4                               Post-Closing Compensation and Benefits.  Buyer shall:

(a)                                 provide to each Available Employee who is actively at work as of the Closing Date, or is on a previously scheduled and approved (by Seller or its Affiliates) leave of absence, and who timely accepts an offer of employment from Buyer made pursuant to this Article 9 and in accordance with the terms of such offer and timely commences active employment with Buyer or one of its Affiliates (each such Available Employee, a “Continuing Employee”), during the twelve (12) month period commencing on the Closing Date (or such shorter period as the applicable Continuing Employee shall remain continuously employed with Buyer and its Affiliates), (i) such base salary or hourly wage rate, as applicable, and cash bonus and including incentive substantially comparable to that provided to similarly-situated employees of Buyer or its applicable Affiliate, (ii) subject to Section 9.4(b), immediate participation in the Buyer or its Affiliates’ benefit plans as of each Continuing Employee’s Hire Date which are provided to similarly situated employees of Buyer or its Affiliates, and (iii) reemployment or hiring, as applicable, to the Available Employees identified in the Employee Letter as “Inactive Available Employees” who are not actively at work as of the Closing Date due to an approved leave of absence, such reemployment or hiring to be effective as of the date, if any, each such Available Employee has been cleared for and returns to active employment and to be in a position substantially comparable to that which such Available Employee has prior to the commencement of his or her absence from active employment, provided, however, that such Available Employee must return to active employment within one hundred fifty (150) days after the Closing or such time period as required by applicable Law.

(b)                                 use Reasonable Efforts to cause each Continuing Employee and his or her eligible dependents (including all such employee’s dependents properly covered immediately prior to the Hire Date by a group health plan maintained by Seller or its Affiliates) to be covered under a group health plan maintained by Buyer or its Affiliate that (i) provides medical, dental and prescription drug benefits coverage to the Continuing Employee and such eligible dependents effective immediately upon the Hire Date and (ii) credits or reimburses such Continuing Employee, for the plan year during which such coverage under such group health plan begins, with any deductibles or co-payments actually paid by such Continuing Employee during such year under a group health plan maintained by Seller or its Affiliates (subject to Buyer’s or its Affiliates’ group health plans deductible and co-payment limits), provided, in all cases, that (i) Seller provides, or causes to be provided, within a reasonable time after Closing such information as Buyer reasonably requires to comply with the foregoing and (ii) if Third Party insurers and administrators do not consent to the foregoing (after Buyer has used

46

Reasonable Efforts to cause Third Party insurers and administrators to consent to the foregoing), Buyer will be deemed to have used Reasonable Efforts to comply therewith;

(c)                                  provide full service credit for purposes of eligibility, vesting and severance benefit determination only (other than to the extent that such credit would result in duplication of benefits with respect to the same period of service, and excepting credit for any defined benefit, money purchase pension or similar plan and for Buyer’s or any of its Affiliate’s equity, equity-based, or other incentive compensation) under employee benefit plans, policies and arrangements made available to Continuing Employees by Buyer or any of its Affiliates on or after the Hire Date which Buyer or its Affiliates provided its employees on the Closing Date to the same extent such Continuing Employee’s service was properly recognized under the analogous type of Business Employee Benefit Plan in which such Continuing Employee participated immediately prior to the Closing Date; provided, that Continuing Employees will be eligible for and accrue vacation and other paid time off benefits at the same rate as a Buyer’s similarly-situated employee with the same amount of service a Continuing Employee has under Seller’s vacation and/or paid time off policy; and

9.5                               Savings Plans.  Effective as of the Closing Date, Buyer shall, or shall cause one of its Affiliates, establish or maintain a defined contribution plan (or plans) and trust (or trusts) intended to qualify under Sections 401(a) and 501(a) of the Code in which all Continuing Employees shall be eligible to participate (“Buyer Savings Plan”) as of the Hire Date.  Buyer shall cause Buyer Savings Plan to accept the direct rollover of electing Continuing Employees’ benefits in cash and, if applicable, up to two promissory notes from the Seller Savings Plan. Buyer shall, if necessary, amend the Buyer Savings Plan to ensure (or otherwise provide for therein) that the obligations set forth in this Section 9.5 are allowed under the Buyer Savings Plan and shall do what is administratively required to satisfy the obligations set forth in this Section 9.5.

9.6                               Seller Offers; Non-Solicitation.  Any Pioneer Entity may make offers of employment to retain or employ the Excluded Employees and the Selective Employees.  In addition, (i) in the event any Available Employee who receives an offer of employment from Buyer or its Affiliate rejects such offer of employment, Seller or any Pioneer Entity may make an offer of employment to retain or employ such Available Employee, and (ii) Seller or any Pioneer Entity may make an offer of employment to retain or employ any Available Employee who does not receive an employment offer from Buyer or its Affiliate. Buyer shall not, and shall cause its Affiliates not to, make an offer of employment to any Excluded Employee in connection with the transactions contemplated by this Agreement or for the one (1) year period after the Closing and, during the one (1) year period after the Closing, Buyer shall not, and shall cause its Affiliates not to, make an offer of employment to any employee of Seller or any of its Affiliates, other than as contemplated pursuant to this Article 9, with whom Buyer or its Affiliates had contact as a result of this Agreement. During the one (1) year period after the Closing, Seller shall not, and shall cause its Affiliates not to, make an offer of employment to any Continuing Employee or other employee of Buyer or any of its Affiliates with whom Seller or its Affiliates had contact as a result of this Agreement. Notwithstanding the foregoing, in all cases, offers resulting from (i) general solicitations made to the applicable market as a whole (e.g., Internet and newspaper advertisements or postings) shall not constitute a violation hereof or (ii) communications between such individual and Seller, Buyer or their respective Affiliates,

47

as applicable, that do not commence until after the applicable Excluded Employee or Continuing Employee, respectively, has terminated employment with Seller, Buyer or their respective Affiliates, as applicable. Further, provided that either Party consults with and receives advance written permission from an authorized representative of the other Party, such Party may solicit and hire any individual whose solicitation and hire would be otherwise prohibited by this Section 9.6.

(e)                                  Subrogation.  If Buyer, Seller or Pioneer is required to make any payment to any Indemnified Party under this Article 11, such Party shall be entitled to subrogation and is hereby granted subrogation rights with respect to all rights and remedies of the Indemnified Party (i) under any insurance maintained by, or for the benefit of, the applicable Indemnified Party or (ii) to any other claims of the applicable Indemnified Party against any Third Party with respect to the Losses giving rise to such payment obligation, but in each case, only to the extent of such required payment.

(f)                                   Schedule Supplement.  From time to time prior to the Closing Date, Seller shall promptly supplement or amend the Disclosure Schedules hereto to correct any matter that would otherwise constitute a breach of any representation or warranty of Seller contained herein solely to the extent that Seller first has Knowledge of such breach after the Execution Date (each a “Schedule Supplement”), and each such Schedule Supplement shall be deemed to be incorporated into and supplement and amend the Disclosure Schedules as of the Closing Date; provided, however, that any such Schedule Supplement shall be disregarded for purposes of, and shall not affect, the determination of the failure or satisfaction of Buyer’s condition to Closing set forth in Section 10.1(a).

(g)                                  Rescission.  Seller, Pioneer and Buyer acknowledge that after the Closing the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained in this Agreement or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement.  As the payment of money shall be adequate compensation, Buyer, Seller and Pioneer waive any right to rescind this Agreement or any of the transactions contemplated hereby.

54

(h)                                 Knowledge.  In the event Buyer has Knowledge of any matter that causes or would be likely to cause any of Seller’s or Pioneer’s representations or warranties to be untrue or inaccurate in any respect, Buyer shall promptly give notice of such matter to Seller and Pioneer.  If Buyer fails to notify Seller of any such matter, then, following the Closing, Buyer shall not be entitled to claim that Seller or Pioneer, as applicable, breached any representation or warranty as a result of such matter.

(i)                                     Materiality Qualifiers. For purposes of calculating Losses under this Article 11 with respect to any breach of a representation or warranty contained in Article 4, Article 5 or Article 6, any “materiality” or “Material Adverse Effect” qualifications in such representations and warranties shall be disregarded (other than Section 4.15(b) and Section 6.13(b).

(j)                                    Calculation of Losses.  Losses shall be determined net of any (i) Third Party insurance proceeds actually received by the Indemnified Party or that would reasonably be expected to be received or receivable by the Indemnified Party through Reasonable Efforts in respect of or related to the event, cause or condition giving rise to such Losses (the “Cause”) and (ii) amounts actually recovered from Third Parties or that would reasonably be expected to be received or receivable by the Indemnified Party through Reasonable Efforts or over time with respect to the Cause, in each case of clause (i) and (ii), taking into account any expenses to obtain such proceeds with respect to such Losses.  Buyer, Seller and Pioneer shall, and shall cause the Buyer Indemnified Parties and Seller Indemnified Parties, as applicable, to, use Reasonable Efforts to collect any amounts available under such Third Party insurance coverage and from any Person alleged to have responsibility.  If a Buyer Indemnified Party or Seller Indemnified Party, as applicable, receives an amount under Third Party insurance coverage or from a Third Party with respect to Losses that were the subject of indemnification under this Article 11 at any time subsequent to indemnification provided hereunder, then such Buyer Indemnified Party or Seller Indemnified Party, as applicable, shall promptly reimburse the applicable Indemnifying Party to the extent of the net amount received, taking into account any expenses to obtain such amounts. Notwithstanding any provision herein to the contrary, Losses shall not include any Non-Recoverable Damages.

11.3                        Procedures.  Except as otherwise set forth in Article 8, claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a)                                 Third Party Claim.  If any Party entitled to seek indemnification under this Agreement (an “Indemnified Party”) receives Notice of the assertion or commencement of any claim asserted against an Indemnified Party by a Third Party (“Third Party Claim”), the Indemnified Party shall as soon as reasonably practicable (i) notify the Party obligated to indemnify such Indemnified Party pursuant hereto (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a Notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), and the basis of the Indemnified Party’s request for indemnification under this Agreement.  Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission.

55

(b)                                 Indemnifying Party.  In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the relevant Claim Notice to notify the Indemnified Party whether it admits or denies its liability to the Indemnified Party with respect to such Third Party Claim.  If the Indemnifying Party admits liability with respect to such Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim only if such Indemnifying Party provides Notice to the Indemnified Party of its election to defend the Indemnified Party against such Third Party Claim at its sole cost and expense within thirty (30) days from the Indemnifying Party’s receipt of the relevant Claim Notice.  The Indemnified Party is authorized, prior to and during such 30 day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.  If the Indemnifying Party notifies the Indemnified Party of its desire to defend the Indemnified Party against such Third Party Claims in accordance with the foregoing, then such Indemnifying Party (the “Assuming Indemnifying Party”) shall have the right and the obligation to diligently defend, at its sole cost and expense such Third Party Claim, with counsel reasonably selected by the Assuming Indemnifying Party, to a final conclusion or settlement at the discretion of the Assuming Indemnifying Party in accordance with this Section 11.3(b).  The Assuming Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Assuming Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the Third Party asserting the claim to all Indemnified Parties affected by the claim and (ii) the settlement agreement does not contain or impose any obligation, limitation, Liability, sanction or restriction upon the Indemnified Party or its Affiliates or the conduct of any business by the Indemnified Party or its Affiliates.  If requested by the Assuming Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Assuming Indemnifying Party, to cooperate with the Assuming Indemnifying Party and its counsel in contesting any Third Party Claim which the Assuming Indemnifying Party elects to contest, including the making of any related reasonable counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person.  The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Assuming Indemnifying Party pursuant to this Section 11.3(b), and except in accordance with the preceding sentence the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c)                                  Indemnified Party.  If the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 11.3(b) or if the Indemnifying Party so elects to defend the Indemnified Party but fails to diligently prosecute or settle such Third Party Claim, then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable costs and expenses (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party.  In such circumstances, the Indemnified Party shall defend the Third Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the

56

Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 11.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d)                                 Direct Claim.  Any claim by an Indemnified Party on account of Losses that does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt Notice thereof, but in any event not later than thirty (30) days after the Indemnified Party obtains actual knowledge of such Direct Claim; provided, however, failure to timely provide such Notice shall not affect the right of the Indemnified Party to indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission.  Such Notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all written background material relevant thereto and shall indicate an estimate of the actual amount of Losses that have been sustained and the projected amount of Losses that may be sustained by the Indemnified Party.  The Indemnifying Party shall have a period of thirty (30) days within which to respond in writing and to either accept or reject such Direct Claim.  If the Indemnifying Party does not so respond within such thirty (30) day period, the Indemnifying Party shall be deemed to have rejected such claim, in which event the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

11.4                        Waiver of Consequential Damages.  NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, NEITHER BUYER, SELLER, PIONEER NOR THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE HEREUNDER TO ANY INDEMNIFIED PARTY FOR ANY NON-RECOVERABLE DAMAGES, EXCEPT TO THE EXTENT ANY SUCH NON-RECOVERABLE DAMAGES ARE INCLUDED IN ANY ACTION BY A THIRD PARTY AGAINST SUCH INDEMNIFIED PARTY AND SUCH NON-RECOVERABLE DAMAGES ARE OTHERWISE INDEMNIFIABLE OR RECOVERABLE LOSSES UNDER THIS AGREEMENT.

11.5                        Waivers and Disclaimers.

(a)                                 Defects.  The Assets are being conveyed and assigned to and accepted by Buyer in their “as is, where is” condition and state of repair, and with all faults and defects, without any representation, or warranty of any kind or nature, express, implied or statutory, including warranties of marketability, quality, condition, conformity to samples, merchantability and/or fitness for a particular purpose, all of which are expressly disclaimed and negated by Seller and Pioneer and waived by Buyer (other than the representations and warranties of Seller and Pioneer set forth in Article 4 and Article 5, respectively).

(b)                                 Additional Disclaimers.  OTHER THAN THE REPRESENTATIONS AND WARRANTIES OF SELLER AND PIONEER SET FORTH IN ARTICLE 4 AND ARTICLE 5, SELLER AND PIONEER EXPRESSLY DISCLAIM AND NEGATE, AND BUYER HEREBY WAIVES, ANY LIABILITY OR RESPONSIBILITY OF SELLER AND PIONEER FOR, (I) ALL REPRESENTATIONS AND WARRANTIES, EXPRESS OR IMPLIED, AT LAW OR IN EQUITY, (II) ANY STATEMENT OR INFORMATION ORALLY OR IN WRITING MADE OR COMMUNICATED TO BUYER OR ANY OF ITS

57

REPRESENTATIVES, INCLUDING (1) ANY STATEMENT OR INFORMATION ORALLY OR IN WRITING MADE OR COMMUNICATED TO BUYER OR ANY OF ITS REPRESENTATIVES BY ANY REPRESENTATIVE OF SELLER, PIONEER OR ANY OF THEIR AFFILIATES OR (2) AS TO THE ACCURACY, MATERIALITY OR COMPLETENESS OF ANY DATA OR RECORDS MADE AVAILABLE TO BUYER WITH RESPECT TO THE ASSETS.

11.6                        Exclusive Remedy and Release.  Except for any claims seeking specific performance or other equitable relief in connection with the failure of any party to perform its covenants hereunder (whether before or after Closing), the indemnification remedies set forth in this Article 11, Section 7.4(b), Section 9.3(b)(iii), Section 9.7, Section 9.9 and this Section 11.6 shall, from and after the Closing, constitute the sole and exclusive remedies of the Parties with respect to any and all claims (whether arising before or after Closing) relating to the subject matter of this Agreement,  the Assets or Seller’s or Pioneer’s ownership or operation of the Assets or the condition of the Assets, including statutory or other claims arising under any Law.

11.7                        Express Negligence Rule.  THE INDEMNIFICATION AND WAIVER PROVISIONS IN THIS AGREEMENT SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OR OTHER FAULT OF THE PERSON SEEKING INDEMNIFICATION OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON THE PERSON SEEKING INDEMNIFICATION.  BUYER, SELLER AND PIONEER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

11.8                        Tax Treatment of Post-Closing Payments.  The Parties agree that any payments made by one Party to the other Party pursuant to this Article 11 shall be treated for all Tax purposes as an adjustment to the Cash Consideration unless otherwise required by applicable Law.

Article 12

(b)                                 by either Buyer, Seller or Pioneer, upon Notice to the other Parties, if any Governmental Authority having competent jurisdiction has issued a final, non-appealable Order, decree, ruling or injunction or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement;

(c)                                  by Buyer (provided Buyer is not in breach of this Agreement such that such breach together with all other breaches by Buyer has prevented or will prevent the satisfaction of any condition to the obligations of Seller or Pioneer at the Closing), upon Notice

58

to Seller and Pioneer, if there has been a breach by Seller or Pioneer of any representation, warranty, covenant or agreement contained in this Agreement that has prevented or will prevent the satisfaction of any condition to the obligations of Buyer at the Closing or if there has been a material breach by Seller or Pioneer of a covenant or agreement to be performed by Seller or Pioneer at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Seller or Pioneer on the earlier of (i) the date that is thirty (30) days after Notice thereof from Buyer or (ii) the Outside Date;

(d)                                 by Seller or Pioneer (provided Seller or Pioneer are not in breach of this Agreement such that such breach together with all other breaches by Seller and Pioneer has prevented or will prevent the satisfaction of any condition to the obligations of Buyer at the Closing), upon Notice to Buyer, if there has been a breach by Buyer of any representation, warranty, covenant or agreement contained in this Agreement that has prevented or will prevent the satisfaction of any condition to the obligations of Seller or Pioneer at the Closing or if there has been a material breach by Buyer of a covenant or agreement to be performed by Buyer at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Buyer on the earlier of (i) the date that is thirty (30) days after Notice thereof from Seller or Pioneer or (ii) the Outside Date;

(f)                                   by Buyer (provided Buyer is not in breach of this Agreement such that such breach together with all other breaches by Buyer has prevented or will prevent the satisfaction of any condition to the obligations of Seller and Pioneer at the Closing) upon Notice from Buyer to Seller or Pioneer if the transactions contemplated at the Closing have not been consummated by the Outside Date.

12.2                        Effect of Termination.

(a)                                 If this Agreement is terminated pursuant to Section 12.1, subject to Section 12.2(b), this Agreement shall become void and of no further force or effect (except for the provisions of Section 1.2, Section 7.4(b), Section 7.8, Section 11.4, this Article 12, Article 13, and Article 14 and any applicable definitions set forth in Section 1.1, all of which shall survive and continue in full force and effect indefinitely); provided, however, the Confidentiality Agreement shall not be affected by a termination of this Agreement.

Seller, Pioneer and Buyer acknowledge and agree that (A) the Termination Fee is a fair and reasonable estimate by the Parties of the actual damages of the applicable payee pursuant to clause (i) or clause (ii) of this Section 12.2(b) and (B) such liquidated damages do not constitute a penalty.

12.3                        Specific Performance.  Each Party acknowledges that the other Parties would be damaged irreparably if the obligations of a Party under this Agreement to be performed at or in connection with the Closing are not performed in accordance with their specific terms or otherwise breached.

14.2                        Assignment.  No Party shall assign this Agreement or any part hereof without the prior written consent of the other Parties and any assignment made without such consent shall be void ab initio; provided, however, that after Closing, any Party shall be entitled to assign their rights under this Agreement to an Affiliate without the prior written consent of the other Parties; provided, further, that any such assignment to an Affiliate shall not release the assigning Party from its obligations hereunder.  Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns.

14.3                        Rights of Third Parties.  Notwithstanding anything contained in this Agreement to the contrary, nothing expressed or implied in this Agreement or in any other Transaction Document is intended or shall be construed to confer upon or give any Person, other than the Parties (and their respective successors and permitted assigns), or the Parties’ respective related Indemnified Parties hereunder, any right or remedies under or by reason of this Agreement or the Transaction Documents; provided that only a Party (and its respective successors and permitted assigns) will have the right to enforce the provisions of this Agreement on its own behalf or on behalf of any of its related Indemnified Parties (but shall not be obligated to do so).

14.4                        Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Any .pdf or other electronic transmission hereof or signature hereon shall, for all purposes, be deemed originals.

14.6                        Disclosure Schedules.  Unless the context otherwise requires, all capitalized terms used in the Disclosure Schedules shall have the respective meanings assigned in this Agreement.  No reference to or disclosure of any item or other matter in the Disclosure Schedules shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedules.  No disclosure in the Disclosure Schedules relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred.  Each disclosure in the Disclosure Schedules shall be deemed to qualify all representations and warranties of Seller or Pioneer, as applicable, notwithstanding the lack of a specific cross reference in the Disclosure Schedules.  The inclusion of any information in the Disclosure Schedules shall not be deemed to be an admission or acknowledgment by Seller or Pioneer, as applicable, in and of itself, that such information is material to or outside the Ordinary Course of the Business of Seller or Pioneer, as applicable, or required to be disclosed on the Disclosure Schedules.

62

14.7                        Amendments.  This Agreement may be amended or modified in whole or in part, and terms and conditions may be waived, only by a duly authorized agreement in writing which makes reference to this Agreement executed by each Party.

14.8                        Publicity.  In addition to the obligations under the Confidentiality Agreement, prior to Closing, all press releases or other public announcement of any nature whatsoever relating to the existence of this Agreement, the contents hereof or the transactions contemplated hereby, and the method of the release for publication thereof, shall be subject to the prior written consent of Buyer, Seller and Pioneer (not to be unreasonably withheld, conditioned or delayed); provided, however, that nothing herein shall restrict disclosures by Buyer, Seller, Pioneer, or their Affiliates (a) to the extent that such disclosures are required by applicable securities or other Laws or the applicable rules of any stock exchange having jurisdiction over the disclosing Party or its Affiliates or (b) to Governmental Authorities and Third Parties holding preferential rights to purchase, rights of consent or other rights that may be applicable to the transactions contemplated by this Agreement, as reasonably necessary to provide notices, seek waivers, amendments or terminations of such rights, or seek such consents.  The Parties agree that neither Buyer, Seller nor Pioneer will have an adequate remedy at law if any of the foregoing Persons violate (or threaten to violate) any of the terms of this Section 14.8.  In such event, Buyer, Seller or Pioneer, as applicable, shall have the right, in addition to any other it may have, to obtain injunctive relief to restrain any breach or threaten breach of the terms of this Section 14.8.

14.9                        Severability.  If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect.  In addition, any such invalid or unenforceable provision shall be replaced by a provision that comes closest to the business objective intended by such invalid or unenforceable provision without being invalid or unenforceable itself.

14.10                 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 an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner.  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, any other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

Pressure Pumping Services Agreement

PRESSURE PUMPING SERVICES AGREEMENT

This Pressure Pumping Services Agreement (this “Agreement”), effective as of the Effective Date (as defined in Article 25), is between Pioneer Natural Resources USA, Inc., a Delaware corporation with its principal place of business at 5205 North O’Connor Blvd., Suite 200, Irving, Texas 75039 (“Company”), and ProPetro Services, Inc., a Texas corporation with its principal place of business at 1706 S. Midkiff, Bldg. B, Midland, Texas 79701 (“Contractor”). Company and Contractor are sometimes hereinafter individually referred to as a “Party,” and collectively as the “Parties.”

WHEREAS, Company is the operator of certain oil and gas wells drilled and to be drilled in certain areas;

WHEREAS, Company desires Contractor to provide dedicated hydraulic fracturing Fleets (as defined in Article 3) to Company for the performance of fracture stimulation pumping services, including all pump down operations associated therewith, and provision of associated products in connection with Company’s operations (the “Services”); and

WHEREAS, Contractor desires to perform, and represents that it has fully-trained personnel capable of performing Services as required by Company;

NOW, THEREFORE, for and in consideration of the covenants and promises herein contained, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto agree as follows:

1.              Master Service/Sales Agreement. This Agreement is subject to the terms and conditions of that certain Amended and Restated Master Service/Sales Agreement by and between Company and Contractor dated May 16, 2016 (as amended, supplemented or otherwise modified, the “MSSA”) which is hereby incorporated by reference into this Agreement.  In the event of any conflict or inconsistency between the terms and conditions of the MSSA and this Agreement, the terms of this Agreement shall govern.

2.              Term.

(a)         The term of this Agreement shall begin on the Effective Date and shall continue for a period ending December 31, 2028 (the “Term”); provided, that Company shall have the right, exercisable in its sole discretion, to terminate this Agreement (a) in whole or (b) in part, with respect to one or more Fleets, effective as of December 31 of each of the calendar years 2022, 2024 and 2026 by providing written notice thereof to Contractor not later than July 1 of such calendar year. Following receipt of written notice from Company to commence initial mobilization, Contractor shall be responsible for the mobilization and demobilization of Contractor’s personnel and equipment and the performance of the Services in accordance with this Agreement. The Parties anticipate that such commencement will occur on or about January 1, 2019 (“Commencement Date”).

(b)         This Agreement supersedes and replaces that certain Pressure Pumping Services Agreement by and between Company and Contractor dated January 23, 2017 (as amended, supplemented or otherwise modified, the “Existing PPSA”) in all respects effective as of the Effective Date.  Except as provided in this Article 2(b), commencing on the Effective Date, (i) the

Parties hereby agree to terminate the Existing PPSA, (ii) Contractor shall cease providing services to Company, and Company will cease obtaining services from Contractor, pursuant to the terms and conditions set forth in the Existing PPSA, and (iii) Contractor will commence providing Services to Company, and Company will commence obtaining Services from Contractor, pursuant to the terms and conditions set forth in this Agreement.  Neither Party will be deemed to have waived, or to have released the other Party from, any claim, issue or dispute arising, becoming known or discovered or asserted after the Effective Date but relating to a Party’s performance or nonperformance under the Existing PPSA.  The resolution of any such claim, issue or dispute will continue to be governed by the terms and conditions of the Existing PPSA.  In addition, Company will remain obligated to pay to Contractor all amounts properly payable by Company pursuant to the Existing PPSA that, in accordance with the regular invoice and payment process, had not been invoiced to or paid by Company as of the Effective Date.  The terms of the Existing PPSA shall survive its termination and remain in full effect for purposes of the matters described in this Article 2(b).

3.              Pricing and Scope of Work.

(a)         Contractor shall perform the Services in accordance with each applicable work order or other instrument used by Company to authorize the performance of the Services and Contractor’s net price book that is mutually agreed to between Company and Contractor (the “Net Price Book”). Rates for items not included in the Net Price Book or expressly provided herein shall be agreed upon in writing by the Parties. The Net Price Book will be subject to adjustments as set forth in Article 4.  Company shall not be liable for any markup by Contractor on goods or services provided by any third party subcontractor or supplier of Contractor.  Additionally, Company shall not be liable for any detention, demurrage, or non-utilization charges incurred by Contractor in connection with trucking services provided by Contractor or its subcontractors in furtherance of the Services, except if and to the extent that any such detention, demurrage, or non-utilization charges are directly caused by any member of the Company Group (as such term is defined in the MSSA), as determined by Company in good faith.

(b)         Beginning on the Commencement Date, Contractor shall deliver eight (8) hydraulic fracturing fleets to Company to perform the Services (“Fleets”), with such Fleets dedicated exclusively to Company throughout the Term. For each Fleet, there shall be (i) sufficient personnel and equipment capable of sustaining maximum treating pressures of 10,000 pounds per square inch and maximum pump rates of 100 barrels per minute for each well in the performance of the Services, (ii) on-site storage equipment capable of holding a minimum of 5,000,000 pounds of proppant, and (iii) sufficient personnel and equipment capable of providing all pump down operations required in connection with the Services.  If Company’s job design for a well requires treating pressures or pump rates in excess of the amounts set forth above, Company will provide Contractor sufficient notice to allow Contractor to secure any additional equipment and materials that may be necessary to satisfy such requirements.  Contractor will be solely responsible for the operation of the equipment, and the equipment shall remain under the control of Contractor at all times.  Contractor shall provide trained and qualified personnel to perform the Services.  In satisfying its Fleet obligations under this Agreement, Contractor will have the sole right to determine the equipment included in each Fleet, subject to (i) Contractor’s compliance with the requirements of this Agreement, and (ii) Contractor consulting with Company within a reasonable period of time (but at least ten (10) days) before changing the then-current configuration or components of any Fleet.

2

(c)          Company hereby grants Contractor a right of first offer (“ROFO”) with respect to any coiled tubing services that may be required by Company as part of the Services (the “Coiled Tubing Services”), subject to the terms and conditions set forth in this Article 3(c).  If Company requires any Coiled Tubing Services, then Company shall provide Contractor with written notice thereof, identifying the location(s), time period(s) and other particulars with respect to the Coiled Tubing Services that Company requires (the “ROFO Offer”).  If Contractor has sufficient coiled tubing equipment available to perform Coiled Tubing Services at the location(s) and during the time period(s) required per a ROFO Offer, then Contractor shall provide such Coiled Tubing Services to Company under the terms of this Agreement and the Pricing Agreement by and between Company and Contractor effective as of the Effective Date.  However, if Contractor does not have such equipment available to perform Coiled Tubing Services at the location(s) and during the time period(s) required per a ROFO Offer, then that ROFO Offer shall be of no further force or effect, the ROFO granted herein shall automatically terminate and be null and void as to the subject Coiled Tubing Services, and Company may procure such Coiled Tubing Services from any third party.  Notwithstanding anything to the contrary contained in this Article 3(c): (i) Contractor will not have a ROFO with respect to any Coiled Tubing Services if, at the time that Company wishes to make a ROFO Offer to Contractor, Contractor is not in compliance with the terms of this Agreement; and (ii) the ROFO granted herein shall automatically terminate and be null and void with respect to any and all Coiled Tubing Services that Company requires after such date on which Contractor has failed to meet any of the key performance indicators for the Coiled Tubing Services that are set forth in Exhibit A.

4.              Periodic Pricing Adjustments.

(a)         Effective as of such date that is six (6) months after the Effective Date and every six (6) months thereafter during the Term (each a “Price Adjustment Date”), Contractor shall apply a price adjustment mechanism that is mutually agreed to between Company and Contractor (the “PAM”) to the materials and services that compose the then-current standard job price that is mutually agreed to between Company and Contractor (the “Standard Job Price”).  Contractor, in consultation with Company, shall make adjustments to the unit prices of line items in the then-current Net Price Book necessary to achieve a revised Standard Job Price reflective of the PAM with the resulting adjustments set forth in a revised Net Price Book to be prepared by Contractor.  Such adjustments shall be effective retroactively and prospectively for all Services that are commenced during the applicable six (6)-month period.  Contractor shall submit the revised Net Price Book and a revised Standard Job Price to Company, along with a pricing memorandum in a form and format agreed upon by the Parties that details the application of the PAM, in each case by the fifteenth (15th) day following the applicable Price Adjustment Date.

(b)         If a Party (i) implements new technology with respect to the Services that materially improves the quality, efficiency, capability, safety, or other performance metrics of the Fleets hereunder, or (ii) identifies new technology that it believes would, if implemented with respect to the Services, achieve such improvements, then that Party will provide the other Party notice thereof.  Promptly thereafter, the Parties will conduct good-faith negotiations (i) if such technology is not yet implemented, to agree to a commercially reasonable plan to acquire and implement such new technology; and (ii) to make equitable adjustments to the Net Price Book, the composition of a Fleet, and the minimum Efficiency Rate and Per Pad Stage Attainment Rate to account for such improvements.

3

5.              Invoicing; Credits.

(a)         Contractor shall issue invoices to Company for the Services on a per-well basis and otherwise in accordance with the MSSA.

(b)         Without limiting Company’s rights or remedies under this Agreement or at law or in equity, Company may deduct any amount that Company determines in good faith is owed by Contractor to Company under this Agreement (each such deduction, a “Credit”) from any charges invoiced by Contractor hereunder or against other amounts owed by Company to Contractor under this Agreement.  Company shall notify Contractor in advance of applying any Credit against any charges invoiced by Contractor hereunder or against other amounts owed by Company to Contractor under this Agreement.  Such Credits shall not limit or affect any right of Company to recover any damages incurred by Company as a result of any failure by Contractor to perform the Services or any other obligation contemplated by this Agreement.  Credits shall not expire and may be held by the Company until fully utilized.  Upon the expiration or any termination of this Agreement, any remaining Credits shall be paid or credited to Company, at Company’s election and in its sole discretion.

6.              Option for Additional Fleets. Notwithstanding anything contained in Article 3 above, the Parties agree that in consideration of U.S. $10 paid by Company to Contractor, the receipt and sufficiency of which is hereby acknowledged, Company has the option, but not the obligation, to add additional incremental Fleets from Contractor (each, an “Additional Fleet”), but not more than two (2) Additional Fleets in any calendar year, which Additional Fleets shall be under the same terms and conditions as set forth in this Agreement.  Such option shall expire on December 31, 2022.  Company shall provide Contractor with nine (9) months’ written notice of its election to exercise its option to add an Additional Fleet.  In addition, during the first year of the Term, Company may add one (1) additional incremental Fleet upon at least sixty (60) days’ written notice to Contractor that will consist of Contractor’s then available equipment and will not constitute a new order (the “First Year Additional Fleet”).  The Parties shall work together in good faith to determine mobilization dates for the First Year Additional Fleet and each Additional Fleet, as applicable; provided, however, Company may postpone the agreed mobilization date for the First Year Additional Fleet by a period of time designated by Company (such postponement period not to exceed thirty (30) days, unless otherwise agreed in writing by the Parties), provided that Company notifies Contractor in writing of such postponement at least thirty (30) days prior to the original agreed mobilization date for the First Year Additional Fleet.  Commencing on their applicable mobilization dates, the First Year Additional Fleet and each Additional Fleet shall be considered a Fleet for all purposes hereof.

7.              Efficiency Rate; Non-Productive Time; Equipment Mobilization.

(a)         Contractor shall be capable of performing the Services in accordance with the requirements of this Agreement on a twenty-four (24) hour basis, seven (7) days a week.  For each well where Contractor is performing the Services, Contractor shall perform the Services at an efficiency rate of at least ninety percent (90%) (“Efficiency Rate”), which shall be calculated as set forth in Exhibit B; provided, however, that for purposes of this Article 7, neither Fleet Mobilization Time (defined below) nor any time period that the Parties may agree to, including a holiday or time period associated with a weather event, shall be Company or Contractor Non-Productive Time (defined below).  “Fleet Mobilization Time” is the amount of time, as is mutually agreed to between Company and Contractor, that each Fleet is allowed to move between pads in order to set up and be Mobilized on Location.  A Fleet will be

4

“Mobilized on Location” when the Fleet is fully mobilized on a Company well-site and fully capable of performing the Services.

(b)         Subject to Article 7(a), (i) each hour or fractional hour that Contractor does not perform the Services when a Fleet is Mobilized on Location (as defined below) for any reason, other than White Space or an Idle Period (each defined below), that is attributable to the sole fault of any member of the Company Group, will be “Company Non-Productive Time” or “Company NPT” and (ii) each hour or fractional hour that Contractor does not perform the Services for any reason not attributable to Company NPT will be “Contractor Non-Productive Time” or “Contractor NPT.”

8.              Stage Attainment Rate.  Upon the completion of each pad, each Contractor Fleet shall be required to achieve a Stage Attainment Rate (as defined below) of ninety-five (95%) (the “Per Pad Stage Attainment Rate”).  “Stage Attainment Rate” shall be determined as follows:

First, calculate the target number of Stages to be attained for a day of Services by a Fleet:

Second, compare the number of Stages actually attained by that Fleet to the target number of Stages to have been attained on that day.

Third, upon that Fleet’s completion of Services for the subject pad, average the daily Stage Attainment Rates applicable to such pad.  An example calculation of the Stage Attainment Rate is attached hereto as Exhibit C.

“Pump Time” means the planned time to complete a Stage, given the fluid volume and pump rate for such Stage, according to Company’s design. 

A “Stage” means the perforation of a portion of the well casing and injection of fluid into the perforated zone, according to Company’s design.  A Stage is completed when a plug is set that completely seals off the portion of the well casing that was perforated and into which fracturing fluid was pumped according to Company’s design.

“Switch-Over Time” means the time that Company allots to Contractor to move its equipment between wells, according to Company’s design. 

9.              Materials and Logistics. Company shall have the right, in Company’s sole discretion and upon at least ninety (90) days’ prior written notice to Contractor, to supply all or a portion of the proppant, proppant trucking, coiled tubing services, friction reducer, high viscosity friction reducer, surfactant, and diesel fuel and trucking (collectively, the “Company Provided Materials”) to Contractor for purposes of Contractor’s performance of the Services, as well as the right to have Contractor provide such materials.  In the event that Company exercises its right to supply any of the Company Provided Materials, Contractor shall make corresponding equitable adjustments to the unit prices contained in the then-current and each subsequent Net Price Book

5

(and not simply the elimination of the applicable line item(s)).  As of the Effective Date, Company elects to provide all proppant. At Company’s election, Company reserves the right to supply any other materials in furtherance of the performance of the Services; provided, however, that Company’s right to supply any other materials in furtherance of the performance of the Services shall not apply if and to the extent that Contractor is expressly required to purchase any quantity of any such materials under any agreements that have been assigned by Company or Pioneer Natural Resources Pumping Services LLC to ProPetro Holding Corp. pursuant to that Purchase and Sale Agreement by and among Company, Pioneer Natural Resources Pumping Services LLC and ProPetro Holding Corp., dated November 12, 2018 (the “PSA”), in each case per the express terms of such agreements as of the date of their assignment by Company (and not as they may be later amended or otherwise modified). 

10.       White Space.

(a)         “White Space” means any full day or period of consecutive full days during which a Fleet is capable of performing the Services in accordance with this Agreement, but is not scheduled by Company to perform the Services. With respect to each Fleet, White Space does not include: (i) the first ten (10) days of Fleet Mobilization Time per quarter; (ii) any Fleet Mobilization Time to the extent Contractor’s time to move such Fleet between pads and set up and be Mobilized on Location exceeds seventy-two (72) hours; (iii) any time period that a Fleet is Mobilized on Location; or (iv) any time period during which a Fleet performs services for a third party customer of Contractor.  The Parties shall work together in good faith to maintain a schedule for the Services that minimizes, to the extent commercially reasonable, the potential for White Space.

(b)         Company shall advise Contractor of any anticipated days of White Space for a Fleet as soon as is reasonably practicable.  Company shall provide to Contractor at least seventy-two (72) hours’ notice of the date for the affected Fleet to resume its performance of the Services following the anticipated White Space (the “Return Date”). Unless otherwise expressly notified by Company in writing, the affected Fleet shall resume its performance of the Services on such Return Date.

11.       Idle Periods. 

(a)         Should Company elect to idle a Fleet, Company may issue a written notice to Contractor regarding such election (an “Idle Period Notice”).  Any time period that a Fleet is idled pursuant to an Idle Period Notice is an “Idle Period.”  An Idle Period shall not be considered White Space.  Upon receipt of an Idle Period Notice, Contractor shall use commercially reasonable efforts to employ the affected Fleet in work with a substitute customer during any such anticipated Idle Period.

(b)         During an Idle Period, Company shall not enter into any agreement with a third party to provide stimulation pumping services that could otherwise be timely performed by an idled Fleet in accordance with the terms of this Agreement.  If Company wishes to re-activate a Fleet idled pursuant to Article 11(a), Company shall provide at least sixty (60) days’ written notice in advance of the Return Date for such Fleet in order to allow Contractor to timely secure personnel and equipment suitable for the Services.  In the event that Contractor fails to achieve the Return Date set forth in a notice issued by Company in accordance with this Article 11(b), Contractor shall be liable to Company for charges in an amount to be mutually agreed by Company and Contractor (such amount, the “Return Date Overage Amount”). 

6

Following Contractor’s receipt of notice from Company of a Return Date applicable to an idled Fleet, Contractor shall not enter in any commitment as to such Fleet that extends beyond the designated Return Date.  However, notwithstanding the foregoing, if, prior to Contractor’s receipt of notice by Company of a Return Date for an idled Fleet, Contractor has entered into a binding agreement with a third party for such Fleet for a term that extends beyond the Return Date specified by Company, (i) Contractor shall have no liability to Company for any Return Date Overage Amounts applicable to days for which such Fleet is so bound; and (ii) Company may enter into an agreement with a third party to perform services that would otherwise be provided by such Fleet.

12.       Reservation Periods. Within ten (10) business days following the beginning of each calendar quarter during the Term, Contractor shall determine the total number of days attributable to (i) White Space for all Fleets that were not subject to an Idle Period during the preceding calendar quarter (the “White Space Period”), and (ii) Idle Period(s) for each Fleet that was subject to an Idle Period.

13.       Venue.  Each Party consents to personal jurisdiction in any action brought in the United States federal and state courts located in the State of Texas with respect to any dispute, claim or controversy arising out of or in relation to or in connection with this Agreement, and each of the Parties agrees that any action with respect to any such dispute, controversy, or claim will be determined exclusively in a state or federal district court located in Dallas County, Texas.  EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH THEY MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH DISPUTE ARISING OUT OF THIS AGREEMENT BROUGHT IN SUCH COURT OR ANY DEFENSE OF INCONVENIENT FORUM FOR THE MAINTENANCE OF SUCH DISPUTE.  EACH PARTY HEREBY IRREVOCABLY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY CLAIM BROUGHT BY IT OR BROUGHT BY THE OTHER PARTY THAT ARISES OUT OF THIS AGREEMENT.

14.       Remedies.

(a)         If Contractor fails to perform any Services in accordance with this Agreement, Company may exercise any one or more of the following remedies:

(i)             provide the affected Services itself or procure such Services from an alternate source, in which case Contractor shall reimburse Company for the costs incurred by Company in providing or procuring such Services to the extent that such costs exceed the applicable Net Price Book prices for such Services (even if such Net Price Book prices were not paid by Company);

(ii)          require Contractor to procure the affected Services from a third party selected by Company and have such third party provide such Services to Company at no additional cost to Company;

(iii)       require Contractor to reimburse Company for any amounts paid by Company to Contractor with respect to the affected Services; and

(iv)      require Contractor to take any other actions that the Company deems to be necessary to timely address Contractor’s failure to perform, which may include (1) re-performing the relevant job, (2) supplementing the affected Fleet or crew, and (3) replacing the affected Fleet or crew.

7

Any period(s) of time during which is Company is exercising any of the remedies set forth in this Article 14(a) shall not be considered Company NPT, Contractor NPT, White Space, or an Idle Period for the Fleet(s) whose performance Company is seeking to remedy.

(b)         The rights and remedies of Company provided in this Article 14 are not exclusive, and are in addition to any other rights and remedies provided under this Agreement or at law or in equity, notwithstanding anything herein to the contrary.

15.       Termination.

(a)         Either Party may terminate this Agreement by delivery of a written termination notice to the other Party, in the event the other Party becomes insolvent, files a petition in bankruptcy, has a petition in involuntary bankruptcy filed against such Party (which petition is not terminated within sixty (60) days of filing), or makes an assignment for the benefit of its creditors. Such termination shall be effective immediately upon delivery of written notice of termination.

(b)         Company may, by delivery of a written termination notice to Contractor:

(i)             Terminate this Agreement with respect to a particular Fleet if such Fleet fails to achieve the Per Pad Stage Attainment Rate (A) for three (3) consecutive pads or (B) for three (3) pads within any rolling six (6)-pad period.  Such termination shall be effective upon the date specified in Company’s termination notice to Contractor and Company shall not have any termination liability to the Contractor under this Agreement; or

(ii)          Terminate this Agreement in its entirety in the event of a Change in Control.  “Change in Control” means the occurrence of any of the following events:

(1)         The acquisition by any person of beneficial ownership (as defined in Rule 13d-3 of the Securities Act of 1934) of securities of ProPetro Holding Corp., a Delaware corporation (“Parent”), that, together with securities held by such person, constitutes 50% or more of either (x) the then outstanding shares of common stock of Parent (the “Outstanding Parent Stock”) or (y) the combined voting power of the then outstanding voting securities of Parent entitled to vote generally in the election of directors (the “Outstanding Parent Voting Securities”); provided, however, that for these purposes, an acquisition by any person pursuant to a transaction which complies with clauses (A), (B) and (C) of clause (3) below shall not constitute a Change in Control;

(2)         A majority of the members of the board of directors of Parent (the “Board”) is replaced during any twelve (12)-month period by directors whose appointment or election is not endorsed by a majority of the members constituting the Board prior to the date of the appointment or election;

(3)         Consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of Parent or an acquisition of assets of another entity (a “Business Combination”), in each case, unless, following such Business Combination, (A) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Parent Stock and Outstanding Parent Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of, respectively,

8

the then outstanding shares of common stock or common equity interests and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors or other governing body, as the case may be, of the entity resulting from such Business Combination (including, without limitation, an entity which as a result of such transaction owns Parent or all or substantially all of Parent’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Parent Stock and Outstanding Parent Voting Securities, as the case may be, (B) no person beneficially owns, directly or indirectly, 50% or more of, respectively, the then outstanding shares of common stock or common equity interests of the entity resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such entity except to the extent that such ownership results solely from ownership of Parent that existed prior to the Business Combination and (C) at least a majority of the members of the board of directors or similar governing body of the entity resulting from such Business Combination, at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination, were members of the board of directors of Parent as of the Effective Date, or became members of the board of directors of Parent after the Effective Date and whose election or appointment or nomination for election by Parent’s stockholders was approved by a vote of at least a majority of the directors then comprising the board of directors of Parent;

(4)         Approval by the stockholders of Parent of a complete liquidation or dissolution of Parent;
