W I T N E S S E T H:

WHEREAS, the Company, Pioneer Parent, Pioneer Investment, Inc., a Delaware corporation and wholly owned indirect subsidiary of Pioneer Parent (“Pioneer Investment”), Spartan Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of Pioneer Investment (“Merger Sub” and together with Pioneer Parent and Pioneer Investment, each, a “Pioneer Party” and collectively, the “Pioneer Parties”), and STSR LLC, an Oklahoma limited liability company, solely in its capacity as the Representative (as defined in the Merger Agreement), previously entered into that certain Agreement and Plan of Merger, dated as of August 30, 2017, attached hereto as Exhibit A (the “Merger Agreement” and the transactions contemplated thereby, the “Merger”), pursuant to which, as of the effective time of the Merger, Pioneer Investment will acquire the Exchanged Company Units (as defined in the Merger Agreement) of the Company by merging Merger Sub with and into the Company, with the Company continuing as the surviving entity in the Merger, in accordance with the Oklahoma Limited Liability Company Act and the Delaware Limited Liability Company Act;

WHEREAS, each of the Rollover Company Members currently owns membership interests in the Company (each such membership interest, a “Company Unit”);

WHEREAS, the Parties desire and the board of directors of Pioneer Parent deems it advisable and in the best interests of its equityholders to, prior to the consummation of the Merger, afford each Rollover Company Member the opportunity to contribute all or a portion of the Company Units held by such Rollover Company Member to Pioneer Parent in exchange for common stock of Pioneer Parent (“Pioneer Parent Stock”), the fair market value of which is $19.42 per share (the “Pioneer Parent Stock Share Price”), and the rights and obligations under the Merger Agreement; and

WHEREAS, each Rollover Company Member desires to so contribute to Pioneer Parent, in accordance with the terms of this Agreement, the number of Company Units held by such Rollover Company Member as is set forth opposite such Rollover Company Member’s name on Exhibit B (each such Company Unit, a “Rollover Company Unit”).

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties do hereby agree as follows:

Article I
CONTRIBUTION

Section 1.01 Contribution of Rollover Company Units. Effective as of the Closing Date (as defined below), each Rollover Company Member hereby contributes, assigns, transfers, conveys and

delivers to Pioneer Parent all of such Rollover Company Member’s right, title and interest in and to the Rollover Company Units held by such Rollover Company Member, and Pioneer Parent hereby accepts such Rollover Company Units as a contribution by such Rollover Company Member to the capital of Pioneer Parent.

Section 1.02 Consideration. As consideration for the contribution by each Rollover Company Member of such Rollover Company Member’s Rollover Company Units, each such Rollover Company Member shall have rights and obligations with respect to such Rollover Company Units pursuant to the Merger Agreement, to which Pioneer Parent is a party, and Pioneer Parent shall issue the number of shares of Pioneer Parent Stock to each such Rollover Company Member as is set forth opposite such Rollover Company Member’s name on Exhibit B, which number of shares of Pioneer Parent Stock shall be equal to (as to each Rollover Company Member, such number of shares, the “Share Consideration”) (a) such Rollover Company Member’s Rollover Consideration (as defined below), divided by (b) the Pioneer Parent Stock Share Price. For purposes of the foregoing calculation, each Rollover Company Member’s “Rollover Consideration” shall be equal to (i) the Closing Merger Consideration (as defined in the Merger Agreement) that such Rollover Company Member would have received if the Closing Merger Consideration had been distributed to the members of the Company immediately prior to the Closing in accordance with Section 4.8 of the Operating Agreement of the Company, dated as of March 1, 2010, as amended by Amendment No. 1, dated as of February 3, 2015, prior to giving effect to the transactions contemplated by this Agreement, multiplied by (ii) such Rollover Company Member’s Rollover Applicable Percentage (as defined in the Merger Agreement) as set forth opposite such Rollover Company Member’s name on Exhibit B.

Section 1.03 Withholding. Notwithstanding any other provision of this Agreement, Pioneer Parent and its Affiliates shall be entitled to deduct and withhold, or cause to be deducted and withheld, from any amounts payable or otherwise deliverable by such Persons to any Rollover Company Member, including any Share Consideration, such amounts as are required to be withheld with respect to the payment or distribution of such consideration under any provision of tax law, and the Rollover Company Members shall indemnify, defend and hold harmless Pioneer Parent and its Affiliates against liability for any such amounts. The Rollover Company Members shall cooperate with Pioneer Parent to minimize the amount of such withholding to the extent permitted by applicable law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid or distributed to the Person to whom such amounts would otherwise have been paid or distributed. For the avoidance of doubt, if Pioneer Parent or any of its Affiliates is entitled to withhold any amount from a Rollover Company Member pursuant to this Section 1.03 and such Rollover Company Member is entitled to receive cash consideration pursuant to the Merger Agreement, Pioneer Parent and its Affiliates shall be entitled to withhold amounts from such cash consideration (in addition to any amounts withheld pursuant to the Merger Agreement) in lieu of withholding from the Share Consideration deliverable pursuant to this Agreement, and such amount shall be treated the same as any other amount withheld pursuant to the Merger Agreement.

COVENANTS

Section 6.01 Non-Competition; Non-Solicitation.

(a) Each of Steve Faurot and Glenn Brown (each a “Restricted Person”) agrees that during the period commencing on the Closing Date and continuing until the fifth anniversary thereof (the “Restricted Period”), such Restricted Person will not, directly or indirectly, own, operate, manage, control, participate in, have any interest in, be employed or engaged in any capacity by, consult with, advise, permit such Restricted Person’s name to be used by, provide services for, or in any manner engage in the Business (as defined below) (including by such Restricted Person alone or in association with any Person) within the Restricted Area (as defined below), including, but not limited to, providing services or products to any Covered Customer (as defined below) that are similar to or competitive with the services or products provided or offered as part of the Business or engaging in any activity that is in competition with the Business within the Restricted Area. Notwithstanding the foregoing, (a) nothing in this Section 6.01(a) shall be deemed to diminish, amend, affect or otherwise modify any other non-competition agreement or covenant binding on such Restricted Person and (b) nothing in this Section 6.01(a) shall prohibit such Restricted Person from owning securities having no more than 2% of the outstanding voting power of any publicly traded competitor, or participating as a passive investor in a private investment fund so long as such Restricted Person does not have any active or managerial roles with respect to such investment, and such private investment fund does not own more than 2% of any publicly traded company engaged in the business of Pioneer Parent, the Company or any of their Affiliates.

(b) Non-Solicitation. Each Restricted Person agrees that during the Restricted Period, such Restricted Person will not, directly or indirectly, on behalf of himself or any other Person (i) solicit, canvass, approach, entice or induce any Covered Customer to cease or lessen such Covered Customer’s business with, or to refrain from doing business with the Company or any of its Affiliates or (ii) solicit, canvass, approach, entice or induce any employee or contractor of Pioneer Parent, the Company or any of their Affiliates to terminate his, her or its employment or engagement therewith.

(c) Consideration; Enforcement. The Restricted Persons acknowledge and agree that the covenants set forth in this Section 6.01 are an express incentive to induce Pioneer Parent to enter into this Agreement and the Pioneer Parties to enter into the Merger Agreement, both of which constitute contracts pursuant to which Restricted Persons are selling interests in a business or part of a business and for which they are receiving valuable consideration. Restricted

Persons further acknowledge that immediately prior to this Agreement and the Merger Agreement, the Restricted Persons were substantial equityholders of the Company and were directly and materially associated with the Company’s goodwill, and that pursuant to this Agreement and the Merger Agreement, and, in connection with the transactions contemplated hereby and thereby, each Restricted Person has sold such Restricted Person’s goodwill in the Company and all of such Restricted Person’s interest in the Company. The Parties and the Restricted Persons agree and acknowledge that the Business is conducted throughout the Restricted Area and the limitations as to time, geographic area and scope of activity to be restrained as set forth in this Section 6.01 are reasonable and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company and its Affiliates, including the protection of the goodwill transferred by the Restricted Persons pursuant to the transaction associated with this Agreement and the Merger Agreement, and that these limitations are intended to comply with the provisions of all applicable laws. The Parties and each Restricted Person further agree and acknowledge that, in the event of a breach or threatened breach by either or both of the Restricted Persons of any of the provisions of this Section 6.01, Pioneer Parent, the Company and their Affiliates shall, individually or collectively, be entitled to seek injunctive relief, as any such breach would cause Pioneer Parent, the Company and their Affiliates irreparable injury for which they would have no adequate remedy at law. The Restricted Persons also agree to waive any requirement for the security or posting by the Restricted Persons of any bond in connection with any such remedy. Nothing herein shall be construed so as to prohibit Pioneer Parent, the Company or any of their Affiliates, collectively or individually, from pursuing any other remedies available hereunder, at law or in equity, for any such breach or threatened breach, including disgorgement of the sums received by the Restricted Persons as a result of their entry into this Agreement. The Restricted Persons further acknowledge and agree that no failure or delay by any of Pioneer Parent, the Company or their Affiliates in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. The Parties agree that the foregoing restrictions in this Section 6.01 are reasonable in all respects and that any breach of the covenants contained in this Section 6.01 would cause irreparable injury to Pioneer Parent, the Company and their Affiliates. Nevertheless, if any of the aforesaid restrictions are found by a court or arbitrator of competent jurisdiction to be unreasonable, or overly broad as to scope, geographic area or time, or otherwise unenforceable, the Parties and each Restricted Person intend for the restrictions set forth in this Section 6.01 to be modified by the court or arbitrator making such determination so as to be reasonable and enforceable to the maximum extent permitted by law and, as so modified, to be fully enforced. By agreeing to this contractual modification prospectively at this time, the Parties and each Restricted Person intend to make this provision enforceable under the law or laws of all applicable states and other jurisdictions so that the entire Section 6.01 as prospectively modified shall remain in full force and effect and shall not be rendered void or illegal.

(d) Definitions. For the purposes of this Article VI:

(i) “Business” means the business and operations that are the same or similar to those performed by the Company and any of its Affiliates as of the date hereof, which shall include the development, manufacturing, selling, marketing, servicing and licensing of downhole completions technology utilizing casing-installed sleeves, including toe sleeves; downhole completions technology utilizing abrasive perforation techniques; coiled tubing
