(b) At the Closing, Pioneer Investment shall pay or cause to be paid or shall deposit or cause to be deposited, as the case may be, the following amounts by wire transfer of immediately available funds pursuant to wire transfer instructions confirmed by the applicable payment recipient in writing, or other applicable payment methods as may be authorized by any particular Company Member pursuant to such Company Member’s Letter of Transmittal, as follows:

(i) Pioneer Investment shall pay or cause to be paid to each lender under the Loan Agreements, to an account designated by such lender in writing, the amount of Debt specified in such lender’s Pay Off Letter (collectively, the sum of such Debt amounts for all such payees being hereinafter referred to as the “Debt Pay-Off Amount”);

(ii) Pioneer Investment shall deposit or cause to be deposited the Aggregate Escrow Amount with the Escrow Agent;

(iii) Pioneer Investment shall pay or cause to be paid all Company Transaction Costs that remain outstanding as of the Closing Date to such account or accounts as are designated by the Company in accordance with Section 5.4 (collectively, the sum of such payments for all payees of Company Transaction Costs being hereinafter referred to as the “Paid Company Transaction Costs”);

(iv) Pioneer Investment shall pay or cause to be paid, to such account as is designated by the Representative in writing, the Aggregate Representative Holdback Amount; and

(v) Pioneer Investment shall pay or cause to be paid to such account as is designated by the Representative in writing, and the Representative shall promptly thereafter pay or cause to be paid, as applicable, to each Company Member that delivers a completed and duly executed letter of transmittal in the form attached hereto as Exhibit C (each, a “Letter of Transmittal”) to the Pioneer Parties on or prior to the Closing Date, an amount in cash, with respect to each Company Member, equal to the product of (A) the Closing Merger Consideration and (B) such Company Member’s Closing Consideration Percentage, in accordance with the computations set forth on Closing Schedule D, an estimate of which is set forth on Schedule D.

(c) Post-Closing Payments. From and after the Closing, Pioneer Investment shall promptly (and in any event within five (5) Business Days after receipt) pay or cause to be paid to such account as is designated by the Representative in writing, and the Representative shall promptly thereafter pay or cause to be paid to each Company Member that delivers a completed and duly executed Letter of Transmittal to the Pioneer Parties at any time after the Closing Date, with respect to all Company Units held by such Company Member, the amount in cash (without interest) that would have been payable to such Company Member pursuant to Section 2.9(b)(v) if such Company Member had delivered such documents on or prior to the Closing Date. Any other payments (including distributions by the Escrow Agent and payments of any Final Adjustment Surplus and Earn-out Amount) to be made to the Representative (for further distribution to each of the Company Members) following the Closing shall be made by Pioneer Investment and the Surviving Entity, the Representative or the Escrow Agent, as applicable.

(d) Unexchanged Company Units. Pioneer Investment and the Representative will, promptly upon receipt thereof, deliver electronically to the Surviving Entity surrendered Letters of Transmittal received by it, and, within five (5) Business Days after the 180th day following the Closing Date, Pioneer Investment will return to the Surviving Entity any portion of the Closing Merger Consideration remaining to be paid to the Company Members pursuant to Section 2.9(b)(v) who have not yet delivered their Letters of Transmittal. Any Company Member shall thereafter be entitled to look only to the Surviving Entity for payment of their claims for the consideration set forth in this Article II without interest thereon. Notwithstanding the foregoing, any portion of the consideration set forth in this Article II remaining to be paid to the Company who have not yet delivered their Letters of Transmittal within five (5) years after the Closing Date (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority) shall, to the extent permitted by Law, become the property of the Surviving Entity free and clear of any claims or interest of any Person previously entitled thereto.

2.10 Closing Adjustment Amount. No later than three (3) Business Days before the Closing Date, the Company shall deliver or cause to be delivered to Pioneer Investment an estimated balance sheet of the Company and the Company Subsidiaries (the “Estimated Closing Balance Sheet”) prepared as of 11:59 p.m. on the date immediately prior to the Closing Date (the “Calculation Time”), which sets forth the Company’s calculation of the Closing Merger Consideration based on the Company’s good faith estimate of the following: (a) the amount of Cash as of the Calculation Time (the “Estimated Cash”), (b) the amount of Debt outstanding as of the Calculation Time (the “Estimated Debt”), and (c) the amount of Working Capital as of the Calculation Time and the resulting calculation of Working Capital Surplus or Working Capital Deficiency as of such time and date (the “Estimated Working Capital Surplus” or the “Estimated

Working Capital Deficiency,” respectively). For purposes of calculating the Estimated Cash, Canadian dollars shall be converted into U.S. dollars using a currency exchange rate based upon the Bank of Canada closing exchange rate on the day immediately prior to the Closing Date. The Estimated Closing Balance Sheet shall be prepared by the Company in accordance with this Agreement and the Accounting Principles. The Company shall consider in good faith any reasonable comments that Pioneer Investment may have in respect of the Estimated Closing Balance Sheet (and shall update the Estimated Closing Balance Sheet prior to the Closing upon mutual agreement by the Parties).

2.11 Final Adjustment Amount.

(a) As promptly as practicable after the Closing Date (but in no event later than ninety (90) days after the Closing Date), Pioneer Investment shall cause the Surviving Entity to prepare and deliver to the Representative a consolidated balance sheet of the Company and the Company Subsidiaries prepared as of 11:59 p.m. on the date immediately prior to the Closing Date (except as otherwise contemplated by this Agreement) (the “Closing Balance Sheet”), which shall set forth the following: (i) the amount of Cash as of the Calculation Time (the “Closing Cash”), (ii) the amount of Debt as of the Calculation Time (the “Closing Debt”), and (iii) the components of Working Capital to enable Pioneer Investment and the Representative on behalf of the Company Members and the UAR Holders to calculate the amount of Working Capital as of the Calculation Time (the “Closing Working Capital”) and the amount of Working Capital Surplus or Working Capital Deficiency, in each case, as of such time and date (the “Closing Working Capital Surplus” or the “Closing Working Capital Deficiency,” as the case may be). For purposes of calculating the Closing Cash, Canadian dollars shall be converted into U.S. dollars using a currency exchange rate based upon the Bank of Canada closing exchange rate on the day immediately prior to the Closing Date. The Closing Balance Sheet shall be prepared in accordance with this Agreement and the Accounting Principles. Following the delivery of the Closing Balance Sheet to the Representative, Pioneer Investment and the Surviving Entity shall afford the Representative and its representatives the opportunity to examine the Closing Balance Sheet, and such supporting schedules, analyses, workpapers and other underlying records or documentation as are reasonably requested and necessary and appropriate. Pioneer Investment and the Surviving Entity shall cooperate with the Representative and its representatives in such examination, including providing answers to reasonable questions asked by the Representative and its representatives, and Pioneer Investment and the Surviving Entity shall promptly make available to the Representative and its representatives any copies of records reasonably requested and necessary and appropriate.

(b) If within thirty (30) days following delivery of the Closing Balance Sheet to the Representative (or such later date as mutually consented to by Pioneer Investment and the Representative, which consent shall not be unreasonably withheld, conditioned or delayed), the Representative has not delivered to Pioneer Investment written notice of its objections to the Closing Balance Sheet (the “Objection Notice”), which Objection Notice must contain a statement describing in reasonable detail the basis of such objections, then the Closing Balance Sheet, Closing Cash, Closing Debt, Closing Working Capital and Closing Working Capital Surplus or Closing Working Capital Deficiency, as applicable, as set forth in or derived from such Closing Balance Sheet shall be deemed final and conclusive and shall be “Final Balance Sheet,” “Final Cash,” “Final Debt,” “Final Working Capital” and “Final Working Capital Surplus” or “Final Working Capital Deficiency,” respectively and as applicable. If the Representative delivers the

Objection Notice within such thirty day (30) period, then Pioneer Investment and the Representative shall endeavor in good faith to resolve the objections, for a period not to exceed fifteen (15) days from the date of delivery of the Objection Notice. The Representative shall afford Pioneer Investment and the Surviving Entity and their representatives the opportunity to examine any Objection Notice, and such supporting schedules, analyses, workpapers, and other underlying records or documentation as are reasonably requested and necessary and appropriate. The Representative shall cooperate with Pioneer Investment, the Surviving Entity and their representatives in such examination, including providing answers to questions asked by Pioneer Investment, the Surviving Entity and their representatives and promptly making available to Pioneer Investment, the Surviving Entity and their representatives any copies of records reasonably requested and necessary and appropriate. If at the end of the fifteen day (15) period there are any objections that remain in dispute, then the remaining objections in dispute shall be submitted for resolution to a nationally recognized accounting firm to be selected jointly by the Representative and Pioneer Investment within the following five (5) Business Days (such jointly selected accounting firm the “Referee”). The Referee shall be jointly instructed by the Parties to determine any unresolved items of the Final Balance Sheet, Final Cash, Final Debt, Final Working Capital and Final Working Capital Surplus or Final Working Capital Deficiency within thirty (30) days after the objections that remain in dispute are submitted to it. If any objections are submitted to the Referee for resolution, (i) each Party shall furnish to the Referee such workpapers and other documents and information relating to such objections as the Referee may request and are available to that Party or its subsidiaries (or its independent public accountants) and will be afforded the opportunity to present to the Referee any material relating to the determination of the matters in dispute and to discuss such determination with the Referee; (ii) to the extent that a value has been assigned to any objection that remains in dispute, the Referee shall not assign a value to such objection that is greater than the greatest value for such objection claimed by any Party or less than the smallest value for such objection claimed by any Party; (iii) the determination by the Referee of Closing Cash, Closing Debt, Closing Working Capital and Closing Working Capital Surplus or Closing Working Capital Deficiency, as set forth in a written notice delivered to both Parties and the Escrow Agent by the Referee, shall be made in accordance with this Agreement and shall be binding and conclusive on the Parties, absent fraud or manifest error and (iv) the costs and expenses of the Referee will be borne by the Parties in such proportion as is appropriate to reflect the relative benefits received by the Pioneer Parties and the Representative on behalf of the Company Members and the UAR Holders from the resolution of the dispute. For example, if the Representative challenges the calculation of the Closing Working Capital by an amount of $100,000, but the Referee determines that the Representative on behalf of the Company Members and the UAR Holders has a valid claim for only $40,000, Pioneer Investment shall bear 40% of the fees and expenses of the Referee and the Representative on behalf of the Company Members and the UAR Holders shall bear the other 60% of such fees and expenses.

(c) To the extent that the Final Adjustment Amount minus the Closing Adjustment Amount is a positive number, such excess (the “Final Adjustment Surplus”) shall be paid by Pioneer Investment within five (5) Business Days of the determination of the Final Adjustment Amount to the Company Members (less the UAR Holders’ UAR Final Adjustment Surplus Amounts, which shall by paid directly by the Pioneer Parties to the UAR Holders, subject to applicable Tax withholding in accordance with Section 2.15); provided, however, that such payments to the Company Members shall be made to the Representative who shall pay to each Company Member that delivered a completed and duly executed Letter of Transmittal to the

Pioneer Parties such Company Member’s portion of the Net Final Adjustment Surplus Amount equal to the product of (A) the Net Final Adjustment Surplus Amount and (B) such Company Member’s Earn-out Percentage. To the extent that the Final Adjustment Amount minus the Closing Adjustment Amount is a negative number, the absolute value of such deficiency (the “Final Adjustment Shortfall”) shall be distributed to Pioneer Investment solely from the Escrow Account. Notwithstanding the foregoing, Pioneer Investment shall disperse any portion of the Net Final Adjustment Surplus remaining to be paid to the Company Members who have not yet delivered Letters of Transmittal to the Surviving Entity to be paid to such Company Members in accordance with Section 2.9(c).

2.12 Earn-out.

(a) Following the Closing, at such time as provided in this Section 2.12, the Pioneer Parties shall pay to the Representative, in accordance with Section 2.12(c), with respect to the Earn-out Period, an amount, if any, calculated as follows (an illustrative calculation of the Earn-out Amount is set forth on Schedule C): if the Actual Gross Profit Amount during the Earn-out Period is greater than the Earn-out Threshold, the Pioneer Parties shall pay or cause to be paid to the Representative on behalf of the Company Members and the UAR Holders, in the aggregate, in accordance with this Section 2.12, an amount equal to (such amount, the “Earn-out Amount”) the product of (A) the Maximum Earn-out Amount multiplied by (B) the lesser of (1) one or (2) the Percentage of Target Gross Profit Amount Achieved.

(b) For purposes of determining whether any Earn-out Amount is due to the Company Members and the UAR Holders, no later than thirty (30) days after the issuance and release of the audited consolidated financial statements for the Company for the fiscal year ending December 31, 2018, which audited consolidated financial statements shall be prepared in accordance with the Accounting Principles, Pioneer Investment shall deliver to the Representative a written statement (the “Earn-out Statement”) setting forth in reasonable detail the calculation of the Actual Gross Profit Amount, together with reasonable supporting documentation thereof. The Pioneer Parties shall take all commercially reasonable steps to cause the above-referenced audited consolidated financial statements of the Company to be completed and delivered on a timely basis. Following the delivery of the Earn-out Statement to the Representative, Pioneer Investment and the Surviving Entity shall afford the Representative and its representatives the opportunity to examine the Earn-out Statement and such supporting schedules, analyses, workpapers and other underlying records or documentation as are reasonably requested and necessary and appropriate. Pioneer Investment, the Surviving Entity and their respective representatives shall cooperate with the Representative in such examination, including providing answers to reasonable questions asked by the Representative and its representatives and promptly making available to the Representative and its representatives any copies of records reasonably requested and necessary and appropriate. If, within thirty (30) days following delivery of the Earn-out Statement to the Representative, the Representative has not delivered to Pioneer Investment written notice (the “Earn-out Objection Notice”) setting forth in reasonable detail the reasons for which the Representative does not agree with the calculation of the Actual Gross Profit Amount set forth in the Earn-out Statement, then the Earn-out Statement and the determination of whether payment of an Earn-out Amount is due based on such Earn-out Statement shall be binding and final for all purposes of this Agreement. If, based on the Actual Gross Profit Amount, an Earn-out Amount is due, such Earn-out Amount shall be due and payable as provided in Section 2.12(c). If the

Representative delivers an Earn-out Objection Notice within such thirty day (30) period, then the Representative and Pioneer Investment shall try to resolve any differences in their respective positions with respect to Pioneer Investment’s calculation of the Actual Gross Profit Amount. If the Representative and Pioneer Investment are unable to agree upon the calculation of the Actual Gross Profit Amount within thirty (30) days after the Representative’s delivery of the Earn-out Objection Notice to Pioneer Investment, then the matter to be resolved (the “Earn-out Dispute”) shall be submitted for resolution to the Referee within the following five (5) Business Days (it being understood that such Referee shall be selected in the same manner as provided in Section 2.11(b)). Pioneer Investment and the Representative shall each provide to the Referee and the other Party a statement of its position as to calculation of the Actual Gross Profit Amount and whether an Earn-out Amount is due within fifteen (15) days from the date of the referral to the Referee. The Referee shall make a written determination as promptly as practicable, but in any event within thirty (30) days after the date on which the dispute is referred to the Referee, by determining the Actual Gross Profit Amount; provided, that the Actual Gross Profit Amount as determined by the Referee may not be greater than the greatest value for Actual Gross Profit Amount claimed by any Party or less than the smallest value for Actual Gross Profit Amount claimed by any Party. If any objections are submitted to the Referee for resolution, each Party shall furnish to the Referee such workpapers and other documents and information relating to such objections as the Referee may request and are available to that Party or its subsidiaries (or its independent public accountants) and will be afforded the opportunity to present to the Referee any material relating to the determination of the matters in dispute and to discuss such determination with the Referee. In the event a dispute is submitted to the Referee in connection with the determination of the Actual Gross Profit Amount, the costs and expenses of the Referee will be borne by the Parties in such proportion as is appropriate to reflect the relative benefits received by the Pioneer Parties and the Representative on behalf of the Company Members and the UAR Holders from the resolution of the Earn-out Dispute. The decision of the Referee shall be final and binding for all purposes of this Agreement and the Earn-out Statement shall be revised, if necessary, to reflect such decision and the Earn-out Statement and thereupon the calculation of the Actual Gross Profit Amount and whether any such Earn-out Amount is due shall be final and binding for all purposes of this Agreement. Such determination by the Referee shall be conclusive and binding upon the Parties, absent fraud or manifest error. With respect to any Earn-out Dispute referred to the Referee, the Referee shall not be authorized or permitted to (A) determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of the Earn-out Dispute in accordance with this Section 2.12(b) or (B) apply any accounting methods, treatments, principles or procedures other than the Accounting Principles. If at any time Pioneer Investment and the Representative resolve their dispute, then, notwithstanding the preceding provisions of this Section 2.12(b), the Referee’s involvement promptly shall be discontinued and the Earn-out Statement shall be revised, if necessary, to reflect such resolution and the Earn-out Statement and thereupon the calculation of the Actual Gross Profit Amount and whether any Earn-out Amount is due shall be final and binding for all purposes of this Agreement.

(c) When the Earn-out Statement becomes final and binding in accordance with Section 2.12(b), if there is any Earn-out Amount owed to the Company Members and the UAR Holders, then the Pioneer Parties shall first pay the portion of the Earn-out Amount owed to Simmons pursuant to the Simmons Engagement Letter set forth on Company Disclosure Schedule 3.13 (the “Simmons Earn-out Amount Fee” and, the Earn-out Amount less the Simmons Earn-out Amount Fee, the “UAR/Company Member Earn-out Amount”), within fifteen

(15) days after the date that the Earn-out Statement becomes final and binding, before paying any UAR Holder’s UAR Earn-out Amount or any Company Member Earn-out Amount owed to the Company Members. The Pioneer Parties shall next pay the UAR Earn-out Amount for all UAR Holders directly to the UAR Holders, subject to applicable Tax withholding in accordance with Section 2.15. The Pioneer Parties shall then pay to the Representative, within fifteen (15) days after the date that the Earn-out Statement becomes final and binding, such Company Member Earn-out Amount by wire transfer of immediately available funds to an account or accounts specified by the Representative. The Representative shall pay to each Company Member that delivered a completed and duly executed Letter of Transmittal to the Pioneer Parties such Company Member’s portion of the Company Member Earn-out Amount, which portion shall be an amount equal to the product of (A) the Company Member Earn-out Amount and (B) the Company Member Earn-out Percentage. Notwithstanding the foregoing, the Pioneer Parties shall disperse any portion of the Company Member Earn-out Amounts remaining to be paid to the Company Members who have not yet delivered Letters of Transmittal to the Surviving Entity to be paid to such Company Members in accordance with Section 2.9(c).

(d) The Representative acknowledges and agrees that from and after the Closing and except as expressly provided to the contrary in this Agreement, (i) the Pioneer Parties and their subsidiaries, as applicable, have the right to operate the Company and each of the Company Subsidiaries (and all components of their businesses) in any way the Pioneer Parties or any of their subsidiaries deem appropriate in their sole discretion, (ii) neither the Pioneer Parties nor any of their subsidiaries shall have any obligation to operate the Company or any of the Company Subsidiaries (or any component of their businesses) in a manner so as to achieve (or maximize the amount of) the Earn-out Amount, (iii) neither the Pioneer Parties nor any of their subsidiaries are under any obligation to operate any business in a manner consistent with the manner in which the Company or any of the Company Subsidiaries operated such business prior to the Closing Date and (iv) the Pioneer Parties and their subsidiaries, as applicable, shall have the right to operate the business in the manner the Pioneer Parties and their subsidiaries, as applicable, believe is prudent and to make such decisions with respect to the Company, the Company Subsidiaries and the businesses as the Pioneer Parties and their subsidiaries, as applicable, believe, in their sole discretion, are reasonable and in the best interests of the Pioneer Parties or any of their subsidiaries and their respective equityholders, including by exercising control and approval over all material capital and contractual obligations undertaken by the Company or any Company Subsidiary (including entry into property leases or sales and supply agreements and making capital expenditures); provided, however, that, with respect to clauses (i) through (iv) above, the Pioneer Parties shall not, directly or indirectly, take any actions in bad faith or with the intent that would have the purpose of avoiding or reducing the Earn-out Amount hereunder; (v) neither the Pioneer Parties nor any of their subsidiaries are under any obligation to continue to serve any existing client after the Closing (subject to any obligations in any Contracts assumed in connection with this Agreement), (vi) the Earn-out Amount is speculative and is subject to numerous factors outside the control of the Pioneer Parties or any of their subsidiaries, (vii) there is no assurance that the Company Members, UAR Holders or Simmons will receive an Earn-out Amount and neither the Pioneer Parties nor any of their subsidiaries have promised or projected an Earn-out Amount, (viii) neither the Pioneer Parties nor any of their subsidiaries owe any fiduciary duty or other express or implied duty to the Company Members, the UAR Holders or Simmons, (ix) the Parties solely intend the express provisions of this Agreement to govern their contractual relationship, and (x) the Representative hereby waives any fiduciary duty or other express or implied duty of the

Pioneer Parties or any of their subsidiaries to the Company Members or the UAR Holders. Notwithstanding anything contained herein to the contrary, the Parties agree that, to the extent that, during the Earn-out Period, one or more of the Pioneer Parties or any of their Affiliates enters into any contract with any third party which contract provides for the provision of goods or services from both the Surviving Entity and one or more of its Affiliates, then, Steve Faurot or Glenn Brown, for so long as at least one of such Persons is employed by the Surviving Entity or one of its Affiliates, shall have the right to approve the amount of revenue from such contract that will be allocated to the Surviving Entity for purposes of calculating the Actual Gross Profit Amount.

2.13 Escrow.

(a) Aggregate Escrow Amount. On or prior to the Closing, the Representative, Pioneer Investment and the Escrow Agent shall enter into the Escrow Agreement, and Pioneer Investment shall deposit an amount equal to Five Million Dollars ($5,000,000) (the “Aggregate Escrow Amount”) into such escrow account at the Closing pursuant to Section 2.9(b)(ii). The Escrow Agent shall hold the Aggregate Escrow Amount in escrow pursuant to the terms of this Agreement and the Escrow Agreement for the period commencing on the Closing Date and ending on the eighteen (18) month anniversary of the Closing Date (the “Escrow Period”). Notwithstanding anything to the contrary in this Agreement or the Escrow Agreement, solely for Tax purposes, the Parties agree to treat the Aggregate Escrow Amount as property of the Company Members and the UAR Holders and any interest or other items of income earned with respect to the Aggregate Escrow Amount as income of the Company Members and the UAR Holders.

(b) Instructions to Escrow Agent.

(i) The Representative and Pioneer Investment covenant and agree to jointly instruct the Escrow Agent in writing promptly (within five (5) Business Days) after the determination of the Final Adjustment Amount to make any disbursements required by Section 2.11(c).

(ii) The Representative covenants and agrees that at any time the Company Members or UAR Holders are obligated to indemnify any Pioneer Indemnified Person for Pioneer Indemnification Claims under Article XI, if requested by Pioneer Investment, the Representative on behalf of the Company Members and UAR Holders, as applicable, shall promptly execute and deliver to the Escrow Agent joint written instructions with Pioneer Investment to release to the Pioneer Indemnified Person such portion of the Aggregate Escrow Amount as is necessary to satisfy the Company Members’ and UAR Holders’, as applicable, indemnification obligations for Pioneer Indemnification Claims under Article XI.

(c) Disbursement of Escrow Amount. Contemporaneous with or as soon as practicable following the release of any remaining amount of the Aggregate Escrow Amount to the Representative for further disbursement to the Company Members and UAR Holders in accordance with the terms of the Escrow Agreement, the Representative shall disburse to the Surviving Entity for further disbursement to the UAR Holders (subject to applicable Tax withholding in accordance with Section 2.15) and directly to each Company Member an amount equal to such UAR Holder’s or Company Member’s, as applicable, Escrow Amount minus (i) the amount of any Losses for which such UAR Holder or Company Member, as applicable, is

determined to be responsible pursuant to Article XI, minus (ii) the portion of any Final Adjustment Shortfall allocable to such UAR Holder or Company Member, as applicable. For the avoidance of doubt, the Surviving Entity shall be responsible for payment of the Simmons Escrow Amount Fee to Simmons.

2.14 Representative Holdback. The amount of One Hundred Fifty Thousand Dollars ($150,000) (the “Aggregate Representative Holdback”) shall be paid at Closing pursuant to Section 2.9(b)(iv) to a segregated client bank account, and shall be held, used and disbursed by or at the direction of the Representative in accordance with Article XIII.

2.15 Withholding. Notwithstanding any other provision of this Agreement, the Pioneer Parties and the Surviving Entity shall be entitled to deduct and withhold, or cause to be deducted and withheld, from any amounts payable or otherwise deliverable pursuant to this Agreement (including amounts payable pursuant to Section 2.7) such amounts as are required to be withheld with respect to the making of such payment under any provision of Tax law, and the Representative and the Company Members shall indemnify, defend and hold harmless the Pioneer Parties and the Surviving Entity against liability for any such amounts. The Representative and the Company Members shall cooperate with the Pioneer Parties and the Surviving Entity 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 to the Person to whom such amounts would otherwise have been paid.

As of the date of this Agreement, there is not pending any material claim against the Company or, to the Knowledge of the Company, any of its controlling Company Members, by a current or former holder of Company Units or any other equity-like securities of the Company, in such former member of the Company’s capacity as such and, to the Knowledge of the Company, no such claim has been threatened.

The Company has the requisite limited liability company power and authority to execute and deliver this Agreement and the other Transaction Documents to which it is a party and to perform its obligations hereunder and thereunder and to consummate the transactions contemplated herein and therein. Upon the receipt of the Company Member Consent, as contemplated herein, the execution, delivery and performance of this Agreement and the other Transaction Documents by the Company and the consummation by the Company of the transactions contemplated herein or therein will have been duly authorized by all necessary limited liability company action on the part of the Company.

Article X

TERMINATION, AMENDMENT AND WAIVER

10.1 Termination. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time:

(a) by mutual written consent of the Pioneer Parties and the Company; or

(b) by either the Pioneer Parties or the Company:

(i) if there shall have been any material breach by the other Party (which, in the case of the right of termination by the Company, shall also include any breach by any of the Pioneer Parties) of any representation, warranty, covenant or agreement set forth in this Agreement, which breach (A) would give rise to the failure of such Party’s condition to the Closing hereunder and (B) either (1) cannot be cured or (2) if it can be cured, has not been cured prior to 5:00 p.m. on the date that is twenty (20) calendar days following receipt by the breaching Party of written notice of such breach (the “Cure Period”); and, without limiting the generality of the foregoing, there shall be no Cure Period for Pioneer Investment’s failure to obtain all funds on or prior to the Closing Date necessary to consummate the Merger and the other transactions contemplated by this Agreement and the other Transaction Documents in accordance with the terms and conditions hereof and thereof (which failure shall constitute a material breach of this Agreement); provided, however, that the right to terminate this Agreement pursuant to this Section 10.1(b)(i) shall not be available to the Pioneer Parties or the Company, as applicable, if such Person is then in breach of any representation, warranty, covenant or agreement contained in this Agreement;

(ii) other than with respect to approvals arising under applicable Antitrust Laws and those in connection with the applicable waiting period under the HSR Act, if a court of competent jurisdiction or other Governmental Authority shall have issued an Order or taken any other action (which Order the Pioneer Parties and the Company shall use their reasonable best efforts to lift), in each case permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and the other Transaction Documents and such Order or other action shall have become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 10.1(b)(ii) shall not be available to any Party who did not use reasonable best efforts to lift any such Order or other action;

(iii) upon a failure of the condition set forth in Section 8.1(a) with respect to obtaining the approvals arising under applicable Antitrust Laws and those in connection with the applicable waiting period under the HSR Act having expired or been terminated; provided, however, that the right to terminate this Agreement under this Section 10.1(b)(iii) shall not be available to any Party whose failure to comply with Section 7.1(b) (subject to the limitations set forth in Section 7.1(c)) has been the primary cause of the condition set forth in Section 8.1(a) not being satisfied; or

(iv) if the Closing shall not have occurred on or before 5:00 p.m. on September 15, 2017 (the “Termination Date”); provided, however, that the right to terminate this Agreement under this clause (iv) shall not be available to any Party whose breach of this Agreement has been the primary cause of, or resulted in, the failure of the Closing to occur on or before such date.

10.2 Effect of Termination. In the event of the termination of this Agreement by either the Company or the Pioneer Parties as provided in Section 10.1, this Agreement shall forthwith become void and there shall be no liability or obligation hereunder on the part of the Pioneer Parties or the Company or their respective Affiliates, managers, directors, officers, employees or Company Members, except that (a) the Company or the Pioneer Parties may have liability as provided in Article I and this Article X and Article XII shall survive such termination, and (b) no such termination shall relieve any Party from liability for a willful and material breach of any term or provision of this Agreement prior to such termination. If more than one provision of Section 10.1 is available to the terminating Party in connection with a termination of this Agreement, the terminating Party may rely on any or all available provisions in Section 10.1 for any such termination.

Article XI

INDEMNIFICATION

11.1 Survival of Representations, Warranties and Agreements. The representations and warranties of the Company, any Rollover Company Member and the Pioneer Parties set forth in this Agreement, the other Transaction Documents, and in any certificate delivered in connection with this Agreement or any of the Transaction Documents and the right of an Indemnified Person to assert any claim for indemnification pursuant to this Article XI with respect thereto shall survive the Closing until 5:00 p.m. on such date that is eighteen (18) months after the Closing Date; provided, however, that the Company Fundamental Representations, the Rollover Company

Member Fundamental Representations, the representations and warranties set forth in Section 3.7 (Taxes) and the Pioneer Fundamental Representations and the right of an Indemnified Person to assert any claim for indemnification pursuant to this Article XI with respect thereto shall survive the Closing until the expiration of the statute of limitations (or in the case of the representations or warranties set forth in Section 3.7 (Taxes), ninety (90) days after such expiration). The covenants and other agreements of the Company, the Rollover Company Members and the Pioneer Parties set forth in this Agreement or in any other Transaction Document that require performance prior to the Closing shall terminate at the Closing; provided, however, that the covenants and other agreements of the Company, the Rollover Company Members and the Pioneer Parties set forth in this Agreement and in the other Transaction Documents that require performance at or after the Closing shall survive the Effective Time until fully performed or fulfilled.

11.2 Indemnification of the Pioneer Indemnified Persons by Company Members.

(a) Subject to the limitations on recourse and recovery set forth in this Article XI, from and after the Closing, each Company Member and each UAR Holder shall (severally but not jointly), based on its Escrow & Holdback Funding Percentage, indemnify, defend and hold harmless the Pioneer Indemnified Persons from and against any and all Losses of any Pioneer Indemnified Person after the Closing, in connection with, arising out of or resulting from (any of such Losses, a “Pioneer Indemnification Claim”):

(i) the inaccuracy or breach of any representation or warranty made (A) by the Company in Article III, (B) by the Company or, in the case of any Company Member, such Company Member in any other Transaction Document (including, for the avoidance of doubt, the Contribution Agreement), or (C) in any certificate delivered by or on behalf of the Company or such Company Member or UAR Holder to the Pioneer Parties prior to the Closing pursuant to this Agreement or any other Transaction Document;

(ii) any nonfulfillment or breach by the Company, the Representative or such Company Member or UAR Holder of any covenant or agreement made in this Agreement or any other Transaction Document; provided, however, that neither the Company Members (other than the Company Member committing such breach) nor the UAR Holders (other than the UAR Holder committing such breach) shall be obligated to indemnify or hold harmless any Pioneer Indemnified Person for any Losses to the extent arising out of any breach that occurs after the Closing Date of any covenant or agreement that by its terms is to be performed solely by such Company Member or UAR Holder, as the case may be, after the Closing Date;

(iii) any and all Seller Taxes;

(iv) any and all Environmental Liability Costs;

(v) any and all Bankruptcy Costs; or

(vi) any Company Transaction Costs owed or payable to any Person by any Pioneer Indemnified Person after the Closing Date (including, for the avoidance of doubt, any payroll and employment Taxes relating to the UAR Earn-out Amounts, if any, payable to the UAR Holders, the UAR Final Adjustment Surplus Amounts, if any, payable to the UAR Holders, each UAR Holder’s Escrow Amount and each UAR Holder’s Representative Holdback Amount).

(b) Minimum Loss. The Pioneer Indemnified Persons shall not be entitled to be indemnified for Losses pursuant to Section 11.2(a)(i) unless and until the aggregate amount of all such Losses exceeds $500,000 (the “Minimum Loss”) and the Pioneer Indemnified Persons otherwise satisfy all other requirements under Section 11.4. After the Minimum Loss is exceeded, Pioneer Indemnified Persons shall be entitled to be paid the entire amount of any Losses pursuant to Section 11.2(a)(i) in excess of (but not including) the Minimum Loss, subject to the limitations on recovery and recourse set forth in this Agreement. The limitations of this Section 11.2(b) shall not apply to Pioneer Indemnification Claims arising under or with respect to any Company Fundamental Representations, any Rollover Company Member Fundamental Representations, any breaches of representations and warranties with respect to Section 3.7 (Taxes) or arising out of or relating to fraud by the Company or any Company Member or UAR Holder prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

(c) Minimum Claim. If any Pioneer Indemnification Claim relating to any single event or series of related events that is indemnifiable under Section 11.2(a)(i) results in aggregate losses to Pioneer Indemnified Persons that do not exceed $25,000, such losses shall not be deemed to be Losses under this Agreement and shall not be eligible for indemnification under this Article XI. The limitations of this Section 11.2(c) shall not apply to Pioneer Indemnification Claims arising under or with respect to any Company Fundamental Representations, any Rollover Company Member Fundamental Representations, any breaches of representations and warranties with respect to Section 3.7 (Taxes) or arising out of or relating to fraud by the Company or any Company Member or UAR Holder prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

(d) Recourse Against Escrow Funds; Cap.

(i) Except in the case of claims for Losses with respect to (A) breaches of Company Fundamental Representations or Rollover Company Member Fundamental Representations that are indemnifiable under Section 11.2(a)(i), (B) Losses arising out of or with respect to any fraud by the Company or any Company Member or UAR Holder prior to the Closing in connection with this Agreement or the transactions contemplated hereby, and (C) Losses that are indemnifiable under Sections 11.2(a)(ii), 11.2(a)(iii), 11.2(a)(iv), 11.2(a)(vi) or 11.2(a)(vi), (clauses (A), (B) and (C) collectively, the “Excluded Claims”), and subject to Section 12.16, each of the Pioneer Parties and the Surviving Entity further acknowledges and agrees that the amounts held in the Escrow Account shall be the sole and exclusive source of funds for satisfaction of all claims by Pioneer Indemnified Persons for Losses or otherwise in connection with, arising out of or resulting from the subject matter of this Agreement, the other Transaction Documents and the transactions contemplated hereby and thereby.

(ii) Except as set forth in Section 13.2 and except in the case of Excluded Claims, no Company Member or UAR Holder shall have any liability with respect to Losses that are indemnifiable under this Agreement or otherwise to the Pioneer Indemnified Persons in connection with this Agreement, any other Transaction Documents or the transactions contemplated hereby or thereby, other than, as applicable, such Company Member’s or UAR Holder’s Escrow Amount, which shall be available to satisfy Losses of Pioneer Indemnified Persons, subject to and in accordance with the terms of this Agreement and the Escrow Agreement.

No Company Member or UAR Holder shall have any liability with respect to Losses resulting from Excluded Claims in excess of the sum of (A) the cash proceeds actually received by such Company Member or such UAR Holder pursuant to the transactions contemplated by this Agreement plus (B) with respect to any Rollover Company Member, the Rollover Amount for such Rollover Company Member. No Company Member or UAR Holder shall have any liability with respect to Losses that are indemnifiable under this Agreement or otherwise to the Pioneer Indemnified Persons in connection with this Agreement or any other Transaction Documents or the transactions contemplated hereby or thereby (including with respect to the Excluded Claims) in excess, as applicable, of such Company Member’s or UAR Holder’s portion of such Pioneer Indemnified Claim, which portion shall be equal, as applicable, to such Company Member’s or UAR Holder’s Escrow & Holdback Funding Percentage. Except to the extent arising out of or relating to fraud by the Company or any Company Member prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby, at and after such time as the liability of the Company Members, the UAR Holders or other Company Member Indemnified Persons have been exhausted (or, with respect to the Escrow Amount, released) the Pioneer Indemnified Persons shall not be entitled to seek indemnity under this Article XI for Losses, and the Pioneer Indemnified Persons shall have no further recourse against any Company Member or UAR Holder for any unpaid Losses of any Pioneer Indemnified Person, and the Company Members and UAR Holders shall have no further liability to any Pioneer Indemnified Person relating to or arising out of this Agreement, or in respect of any other Transaction Document or any theory of law or equity or in respect of any oral representations and warranties made or alleged to be made in connection herewith or therewith, whether by or through attempted piercing of the corporate veil, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any Applicable Law, or otherwise.

11.3 Indemnification of the Company Member Indemnified Persons.

(a) Subject to the limitations on recourse and recovery set forth in this Article XI, from and after the Closing, Pioneer Parent, Pioneer Investment and the Surviving Entity, jointly and severally, shall indemnify, defend and hold harmless the Company Member Indemnified Persons from and against any and all Losses of any Company Member Indemnified Person after the Closing in connection with, arising out of or resulting from (any of such Losses, a “Company Member Indemnification Claim”):

(i) the inaccuracy or breach of any representation or warranty made by the Pioneer Parties in Article IV, in any other Transaction Document, or in any certificate delivered by or on behalf of the Pioneer Parties or to the Company or to the Representative for the benefit of the Company Members or the UAR Holders in connection with this Agreement or any other Transaction Document; or

(ii) any nonfulfillment or breach of any covenant or agreement (A) made by the Pioneer Parties under this Agreement or any other Transaction Document or (B) made by the Surviving Entity under this Agreement or any other Transaction Document and which is required to be performed at or after the Closing.

(b) Minimum Loss. The Company Member Indemnified Persons shall not be entitled to be indemnified for Losses pursuant to Section 11.3(a)(i) unless and until the aggregate

amount of all such Losses exceeds the Minimum Loss and otherwise satisfy all other requirements under Section 11.4. After the Minimum Loss is exceeded, Company Member Indemnified Persons shall be entitled to be paid the entire amount of any Losses pursuant to Section 11.3(a)(i) in excess of (but not including) the Minimum Loss, subject to the limitations on recovery and recourse set forth in this Agreement. The limitations of this Section 11.3(b) shall not apply to Company Member Indemnification Claims arising under or with respect any Pioneer Fundamental Representations or arising out of or relating to fraud by the Pioneer Parties prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

(c) Minimum Claim. If any Company Member Indemnification Claim relating to any single event or series of related events that is indemnifiable under Section 11.3(a)(i) results in aggregate Losses to Company Member Indemnified Persons that do not exceed $25,000, such Losses shall not be deemed to be Losses under this Agreement and shall not be eligible for indemnification under this Article XI. The limitations of this Section 11.3(c) shall not apply to Company Member Indemnification Claims arising under or with respect to any Pioneer Fundamental Representations or arising out of or relating to fraud by the Pioneer Parties prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

(d) Caps. In no event will the Company Member Indemnified Persons be entitled to be indemnified for Losses pursuant to Section 11.3(a)(i) to the extent that such amounts, in the aggregate, exceed the aggregate Rollover Amount of all Rollover Company Members. The limitations of this Section 11.3(d) shall not apply to Pioneer Indemnification Claims arising under or with respect to any Pioneer Fundamental Representations or arising out of or relating to fraud by the Pioneer Parties prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

11.4 Limitations.

(a) Limitation as to Time. No Indemnifying Person shall be liable for any Losses that are indemnifiable under Sections 11.2 or 11.3 unless a written claim for indemnification under this Agreement is delivered by the Indemnified Person to the Indemnifying Person with respect thereto prior to 5:00 p.m., on the last day of the respective survival period (if any) as specified in Section 11.1. If notice of a claim is given prior to the expiration of the applicable survival period (if any), that portion of such representation, warranty, covenant or agreement relating to the claim shall continue (for purposes of such claim only) until such claim is fully resolved.

(b) Sole and Exclusive Remedy. Each of the Pioneer Parties and the Representative on behalf of the Company Members and the UAR Holders acknowledges and agrees that, after the Closing, notwithstanding any other provision of this Agreement to the contrary, subject to Section 12.16, and except to the extent arising out of or relating to fraud by the Company, any Company Member or UAR Holder or any Pioneer Party prior to the Closing in connection with this Agreement or the transactions contemplated hereby, the sole and exclusive remedy of the Pioneer Indemnified Persons and the Company Member Indemnified Persons with respect to claims for Losses or otherwise in connection with, arising out of or resulting from the

subject matter of this Agreement and the other Transaction Documents and the transactions contemplated hereby and thereby shall be in accordance with, and limited solely to indemnification under, the provisions of this Article XI. After the Closing, and except to the extent arising out of or relating to fraud by the Company or any Company Member or UAR Holder prior to the Closing in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby, each of the Pioneer Parties and the Representative on behalf of the Company Members and the UAR Holders hereby releases, acquits and discharges forever any and all claims and remedies that the Pioneer Indemnified Persons or the Company Member Indemnified Persons may have against the other Parties under Applicable Laws and agrees to rely solely and exclusively on this Article XI to remedy any Losses incurred pursuant to this Agreement, the other Transaction Documents and the transactions contemplated hereby and thereby.

(c) Materiality. For purposes of this Article XI, (i) the determination of whether a breach of a representation or warranty of the Company or the Pioneer Parties has occurred shall be made without giving effect to any limitation or qualification as to materiality, Material Adverse Effect or words of similar import and (ii) the amount of Losses in respect of any breach of a representation or warranty by the Company or the Pioneer Parties shall be determined without regard to any limitation or qualification as to materiality, Material Adverse Effect or words of similar import set forth in such representation or warranty.

(d) Characterization of Payments. For all Tax purposes, the Parties agree to treat (and shall cause each of their respective Affiliates to treat) any indemnity payment under this Agreement (other than an indemnity payment under Section 13.2) as an adjustment to the consideration payable to the Company Members and UAR Holders pursuant to Article II, except to the extent required by Applicable Law.

11.5 Third Party Claims.

(a) Promptly after receipt by any Indemnified Person of notice of the commencement or assertion of any action, proceeding, demand, claim or investigation by a third party (including any investigation, notice, request for information or other communication from any Governmental Authority with respect to any Pre-Closing Period or Straddle Period) or circumstances which, with the lapse of time, such Indemnified Person reasonably believes is likely to give rise to an action, proceeding, demand, claim or investigation by a third party (an “Asserted Liability”) that would reasonably be expected to form the basis of or result in a Loss, such Indemnified Person shall promptly give written notice thereof (the “Claims Notice”) to Pioneer Parent and Pioneer Investment (if Pioneer Parent, Pioneer Investment or the Surviving Entity is the Indemnifying Person) or the Representative (if the Company Members or UAR Holders are the Indemnifying Persons). The Claims Notice shall describe the Asserted Liability in reasonable detail, and shall indicate the amount (estimated, if necessary) of the Loss that has been or may be suffered. Subject to the limitations set forth in Sections 11.1 and 11.4, the failure of the Indemnified Person to promptly provide a Claims Notice shall not amount to a waiver of such claim unless and only to the extent that the resulting delay materially and adversely prejudices the position of the Indemnifying Person with respect to such claim.

(b) The Indemnifying Person shall be, subject to the limitations set forth in this Section 11.5, entitled to assume control of and appoint lead counsel for such defense; provided, however, that the Indemnifying Persons shall not have the right to assume control of the defense of any Asserted Liability (i) to the extent that the object of such Asserted Liability is (A) to obtain an injunction, restraining order, declaratory relief or other non-monetary relief against the Indemnified Person which, if successful, would materially adversely affect the business, operations, assets, or financial condition of the Indemnified Person, or (B) Taxes imposed on the Company, any Company Subsidiary or the Pioneer Parties or for which the Company, any Company Subsidiary or the Pioneer Parties may be liable, (ii) if the named parties to any such action or proceeding (including any impleaded parties) include both the Indemnified Persons and the Indemnifying Persons and the former shall have been advised in writing by counsel (with a copy to the Indemnifying Persons) that there are one or more legal or equitable defenses available to them that are different from or additional to those available to Indemnifying Persons; provided, further, that to exercise such rights the Indemnifying Person must give notice to the Indemnified Person within thirty (30) days after receipt of any such Claims Notice whether it is assuming control of and appointing lead counsel for such defense. If the Indemnifying Person does not give such notice within such thirty day period, then the Indemnified Person shall have the right to assume control of the defense thereof at the cost and expense of the Indemnifying Person, subject to the limitations of liability and other limits set forth in Section 11.4. In the case of any Asserted Liability described in clause(i)(B) of the first sentence of this Section 11.5(b), the Pioneer Parties and the Company shall be entitled to assume control of and appoint lead counsel for such defense.

(c) If the Indemnifying Person shall assume the control of the defense of the Asserted Liability in accordance with the provisions of this Section 11.5, (i) the Indemnifying Person shall obtain the prior written consent of the Indemnified Person (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement, compromise, admission or acknowledgement of the validity of such Asserted Liability if the settlement does not unconditionally release the Indemnified Person from all liabilities and obligations with respect to such Asserted Liability or the settlement imposes injunctive or other equitable relief against the Indemnified Person and (ii) the Indemnified Person shall be entitled to participate in the defense of such Asserted Liability and to employ separate counsel of its choice for such purpose. The fees, costs and expenses of any such separate counsel to the Indemnified Person pursuant to this Section 11.5 shall be paid by the Indemnified Person; provided, however, that the Indemnifying Person shall pay the fees, costs and expenses of such counsel if (A) the employment of separate counsel shall have been authorized in writing by the Indemnifying Person in connection with the defense of such Asserted Liability or (B) the Indemnified Person’s legal counsel shall have advised the Indemnifying Person in writing, with a copy delivered to the Indemnifying Person, that a material conflict of interest exists that would make it inappropriate under applicable standards of professional conduct to have common counsel, subject to the limitations of liability and other limits set forth in Section 11.4.

(d) If the Indemnified Person shall assume the control of the defense of any Asserted Liability in accordance with the provisions of this Section 11.5, (i) the Indemnified Person shall obtain the prior written consent of the Indemnifying Person before entering into any settlement, compromise, admission or acknowledgement of the validity of such Asserted Liability, which consent shall not be unreasonably withheld and (ii) the Indemnifying Person shall be

entitled to participate, at its cost and expense, in the defense of such Asserted Liability and to employ separate counsel of its choice for such purpose.

(e) Each Party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Asserted Liability and shall furnish or cause to be furnished such records, information and testimony (subject to any applicable confidentiality agreement), and attend such conferences, discovery proceedings, hearings, trials or appeals as may be reasonably requested in connection therewith. Both the Indemnified Person and the Indemnifying Person, as the case may be, shall keep the other Person fully informed of the status of such claim and any related proceedings at all stages thereof where such Person is not represented by its own counsel. The Parties agree to cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all confidential information, and all communications between any Party and counsel responsible for or participating in the defense of any claim shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

(f) Notwithstanding anything to the contrary set forth in this Article XI, the Representative shall assume control of the Company’s defense of the Bankruptcy Claim, and, subject to the provisions of Section 11.5(c)(i), shall have the authority to enter into any settlement, compromise or other resolution of the Bankruptcy Claim. For purposes of this Section 11.5(f), the Bankruptcy Claim shall be deemed an Asserted Liability. The fees, costs and expenses of the Representative’s legal counsel, any experts (including expert witnesses), consultants and other representatives engaged by it in connection with (i) the Representative’s assumption of the defense of an Asserted Liability pursuant to this Section 11.5, either on behalf of the Company Member Indemnified Persons as Indemnified Persons or the Company Members or UAR Holders as Indemnifying Persons or (ii) the Representative’s participation in the defense of an Asserted Liability pursuant to this Section 11.5, either on behalf of the Company Member Indemnified Persons as Indemnified Persons or the Company Members or UAR Holders as Indemnifying Persons, in each case, shall be unlimited and shall be paid out of the Representative Holdback.

11.6 Direct Claims. In any case in which an Indemnified Person seeks indemnification hereunder which is not subject to Section 11.5 because no Asserted Liability is involved, the Indemnified Person shall promptly notify the Indemnifying Person in writing of any Losses that such Indemnified Person claims are subject to indemnification under the terms hereof. Subject to the limitations set forth in Sections 11.1, 11.2, 11.3, 11.4, the failure of the Indemnified Person to provide prompt notice of such claim shall not amount to a waiver of such claim unless and only to the extent that the resulting delay materially prejudices the position of the Indemnifying Person with respect to such claim.

11.7 Other Claims. In connection with any Losses for which an Indemnified Person may seek indemnification under this Article XI, such Indemnified Person shall use its commercially reasonable efforts to seek and pursue any available insurance coverage or other claims against third parties that such Indemnified Person may have in respect of such Losses (provided that the costs or seeking and pursuing such items shall constitute Losses hereunder).

11.8 Express Negligence. THE PARTIES INTEND THAT THE INDEMNITIES SET FORTH IN THIS ARTICLE XI BE CONSTRUED AND APPLIED AS WRITTEN ABOVE,

NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY. WITHOUT LIMITING THE FOREGOING, SUCH INDEMNITIES WILL APPLY NOTWITHSTANDING ANY STATE’S “EXPRESS NEGLIGENCE” OR SIMILAR RULE THAT WOULD DENY COVERAGE BASED ON AN INDEMNIFIED PARTY’S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. IT IS THE INTENT OF THE PARTIES THAT, TO THE EXTENT PROVIDED ABOVE, THE INDEMNITIES SET FORTH IN THIS ARTICLE XI WILL APPLY TO AN INDEMNIFIED PARTY’S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. THE PARTIES AGREE THAT THIS PROVISION IS “CONSPICUOUS” FOR PURPOSES OF ALL STATE LAWS.

Article XII

GENERAL PROVISIONS

12.1 Amendment and Modification. This Agreement may be amended only by a written agreement executed by the Parties, provided, however, that no amendment shall be made which by Applicable Law requires further approval by a Party’s stockholders or members, as applicable, without such further approval.

12.2 Waiver of Compliance. Any failure of the Pioneer Parties, on the one hand, or the Company (prior to Closing) or the Representative on behalf of the Company Members or the UAR Holders, on the other hand, to comply with any obligation, covenant, agreement or condition contained herein may be waived only if set forth in an instrument in writing signed by the Party or Parties to be bound by such waiver (including, if such waiver is after the Closing, the third party beneficiaries set forth in Section 12.5), but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any other failure.

12.3 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Applicable Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated herein is not affected in any manner materially adverse to any Party. Upon any determination by a Governmental Authority that any term or other provision hereof is invalid, illegal or incapable of being enforced, the Governmental Authority making such determination is authorized and instructed to modify this Agreement so as to effect the original intent of the Parties as closely as possible in order that the transactions contemplated herein are consummated as originally contemplated to the fullest extent possible.

12.4 Expenses and Obligations. Except as otherwise expressly provided in this Agreement, all costs and expenses incurred by the Parties in connection with the transactions contemplated by this Agreement shall be borne solely and entirely by the Party that has incurred such expenses.

12.5 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors and permitted assigns. Nothing in this Agreement is intended to confer upon any other Person any rights or remedies of any nature whatsoever under

or by reason of this Agreement except as expressly set forth herein. Notwithstanding the foregoing, from and after the Closing, as may be applicable, Article II is made for the benefit of the Company Members and, as applicable, the UAR Holders, Section 6.1 is made for the benefit of the D&O Indemnified Persons, Section 12.12 is made for the benefit of the Non-Recourse Persons and Article XI is made for the benefit of the Pioneer Indemnified Persons and the Company Member Indemnified Persons. From and after the Closing, all of the express third party beneficiaries shall be entitled to enforce such provisions and to avail themselves of the benefits of any remedy for any breach of such provisions, all to the same extent as if such Persons were parties to this Agreement.

12.6 Notices. All notices and other communications hereunder shall be in writing and shall be deemed given if delivered by hand, mailed by registered or certified mail (return receipt requested), sent by email or sent by Federal Express or other recognized overnight courier to the Parties at the following addresses (or at such other address for a Party as shall be specified by like notice):

The headings, if any, of the individual sections of each of the Company Disclosure Schedules are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Schedules are arranged in sections corresponding to those contained in this Agreement merely for convenience, and, except as expressly set forth on the Company Disclosure Schedule, the disclosure of an item in one section of the Company Disclosure Schedules as an exception to a particular representation or warranty shall be deemed adequately disclosed as an exception with respect to all other representations or warranties to the extent that the relevance of such item to such representations or warranties is reasonably apparent on the face of such item, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Schedules with respect to such other representations or warranties or an appropriate cross reference thereto.

(c) The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the Company Disclosure Schedules is not intended and shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the Parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

The words “ordinary course of business” shall mean ordinary course of business, consistent with past custom and practice, including with respect to timing, frequency and magnitude.

(e) For the avoidance of doubt, no dollar amount shall be (or is intended to be) included, in whole or in part (either as an increase or a reduction), more than once in the calculation of (including any component of) any of the Closing Merger Consideration.

12.12 Affiliate Liability. Except to the extent a named Party to this Agreement, and subject in all cases to the terms and conditions of and limitations herein, the Parties acknowledge and agree that no past, present or future director, manager, officer, employee, incorporator, member, partner, stockholder, agent, attorney, representative, Affiliate or financing source of any of the Parties to this Agreement (each, a “Non-Recourse Person”), in such capacity, shall have any liability or responsibility (in contract, tort or otherwise) for any liabilities of any Party, as applicable, under this Agreement or the other Transaction Documents for any claim based on, in respect of, or by reason of, the transactions contemplated hereby and thereby. This Agreement may only be enforced against, and any action based upon, arising out of, or related to this Agreement, or the negotiation, execution or performance of this Agreement, may only be brought against the entities that are expressly named as Parties hereto and then only with respect to the specific obligations set forth herein with respect to such Party. Each Non-Recourse Person is expressly intended as a third party beneficiary of this Section 12.12. For the avoidance of doubt, (a) the Company Members shall be deemed parties to this Agreement and shall, subject to the terms of this Agreement, be directly liable for the obligations set forth herein pertaining to Company Members and (b) the UAR Holders shall be deemed parties to this Agreement and shall, subject to the terms of this Agreement, be directly liable for the obligations set forth herein pertaining to UAR Holders.

12.13 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CONFLICTS OF LAW PRINCIPLES THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAW OF THE STATE OF DELAWARE.

12.14 Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY HEREBY IRREVOCABLY WAIVES AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING IN WHOLE OR IN PART UNDER, RELATED TO, BASED ON, OR IN CONNECTION WITH, THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN TORT OR CONTRACT OR OTHERWISE. ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 12.14 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

12.15 Consent to Jurisdiction; Venue.

(a) The Parties submit to the personal jurisdiction of the courts of the State of Delaware and the Federal courts of the United States sitting in the State of Delaware, and any appellate court from any such state or Federal court, and hereby irrevocably and unconditionally agree that all claims with respect to any such claim may be heard and determined in such Delaware court or, to the extent permitted by law, in such Federal court. The Parties agree that a final judgment in any such claim shall be conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by law.

(b) Each of the Parties irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any related matter in any Delaware state or Federal court located in the State of Delaware and the defense of an inconvenient forum to the maintenance of such claim in any such court.

12.16 Remedies.

(a) The Parties hereby agree that irreparable damage may occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies may not be an adequate remedy for any such damages. Accordingly, the Parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or the Pioneer Parties on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company or the Representative, on the one hand, and the Pioneer Parties, on the other hand, shall be entitled to seek an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement by the other Party, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other Parties under this Agreement.

(b) The Company and the Representative on behalf of the Company Members and the UAR Holders, on the one hand, and the Pioneer Parties, on the other hand, hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by the Company or the

Pioneer Parties, as applicable, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the Company, the Representative, Company Members, the UAR Holders, or the Pioneer Parties, as applicable, under this Agreement. Any Party seeking an injunction or injunctions to prevent breaches or threatened breaches of, or to enforce compliance with, the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with such Order. The Parties further agree that (i) by seeking the remedies provided for in this Section 12.16, a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement (including monetary damages or indemnification) and (ii) nothing set forth in this Section 12.16 shall require any Party to institute any legal action or claim for (or limit any Party’s right to institute any legal action or claim for) specific performance under this Section 12.16 prior or as a condition to exercising any termination right under Article X (and pursuing damages after such termination), nor shall the commencement of any legal action or claim pursuant to this Section 12.16 or anything set forth in this Section 12.16 restrict or limit any Party’s right to terminate this Agreement in accordance with the terms of Article X or pursue any other remedies under this Agreement that may be available then or thereafter.

(c) Except as otherwise set forth in this Agreement, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

Article XIII

THE REPRESENTATIVE

13.1 Authorization of the Representative.

(a) The Representative hereby is appointed, authorized and empowered to act as the agent of the Company Members and the UAR Holders in connection with, and to facilitate the consummation of the transactions contemplated by, this Agreement and the other Transaction Documents, and in connection with the activities to be performed on behalf of the Company Members or the UAR Holders, as applicable, under this Agreement and the Escrow Agreement, for the purposes and with the powers and authority hereinafter set forth in this Article XIII and in the Escrow Agreement, which shall include the full power and authority:

(i) to execute and deliver the Escrow Agreement (with such modifications or changes thereto as to which the Representative, in its reasonable discretion, shall have consented to) and to agree to such amendments or modifications thereto as the Representative, in its reasonable discretion, may deem necessary or desirable to give effect to the matters set forth in Article XI and this Article XIII;

(ii) to take such actions and to execute and deliver such amendments, modifications, waivers and consents in connection with this Agreement and the other Transaction Documents and the consummation of the transactions contemplated hereby and thereby as the

Representative, in its reasonable discretion, may deem necessary or desirable to give effect to the intentions of this Agreement and the other Transaction Documents;

(iii) as the Representative of the Company Members and the UAR Holders, to enforce and protect the rights and interests of the Company Members and the UAR Holders, as applicable, and to enforce and protect the rights and interests of the Representative arising out of or under or in any manner relating to this Agreement, the Escrow Agreement, and each other Transaction Document and, in connection therewith, to (A) resolve, on behalf of the Company Members, all questions, disputes, conflicts and controversies concerning (1) the determination of any amounts pursuant to Article II and (2) Indemnification Claims pursuant to Article XI; (B) employ such agents, consultants and professionals, to delegate authority to its agents, to take such actions and to execute such documents on behalf of the Company Members or the UAR Holders, as applicable, in connection with Article II and Article XI and the Escrow Agreement as the Representative, in its reasonable discretion, deems to be in the best interest of the Company Members or the UAR Holders, as applicable; (C) assert or institute any claim, action, proceeding or investigation; (D) investigate, defend, contest or litigate any claim, action, proceeding or investigation initiated by Pioneer Parent or Pioneer Investment, or any other Person, against the Representative, the Aggregate Escrow Amount, and following the Closing receive and process on behalf any or all Company Members or UAR Holders in any such claim, action, proceeding or investigation and compromise or settle on such terms as the Representative shall determine to be appropriate, give receipts, releases and discharges on behalf of all of Company Members or UAR Holders, as applicable, with respect to any such claim, action, proceeding or investigation on behalf of the Company Members; (E) file any proofs, debts, claims and petitions as the Representative may deem advisable or necessary on behalf of the Company Members; (F) settle or compromise on behalf of the Company Members any claims asserted under Article II or Article XI or under the Escrow Agreement; (G) assume, on behalf of all of Company Members or UAR Holders, as applicable, the defense of any claim that is the basis of any claim asserted under Article II or Article XI or under the Escrow Agreement; and (H) on behalf of the Company Members, file and prosecute appeals from any decision, judgment or award rendered in any of the foregoing claims, actions, proceedings or investigations, it being understood that the Representative shall not have any obligation to take any such actions, and shall not have liability for any failure to take any such action;

(iv) to enforce payment of the Aggregate Escrow Amount and of any other amounts payable to the Company Members or the UAR Holders, in each case on behalf of Company Members or UAR Holders, as applicable;

(v) to authorize and cause to be paid out of the Aggregate Escrow Amount any amounts pursuant to this Agreement and the Escrow Agreement;

(vi) to waive or refrain from enforcing any right of any Company Member, UAR Holder or the Representative arising out of or under or in any manner relating to this Agreement, the Escrow Agreement or any other Transaction Document; and

(vii) to make, execute, acknowledge and deliver all such other agreements, guarantees, orders, receipts, endorsements, notices, requests, instructions, certificates, stock powers, letters and other writings, and, in general, to do any and all things and to take any

and all action that the Representative, in its sole and absolute direction, may consider necessary or proper or convenient in connection with or to carry out the activities described in clauses (i) through (vi) above and the transactions contemplated by this Agreement, the Escrow Agreement and the other Transaction Documents.

(b) Pioneer Parent, Pioneer Investment the Company, the Surviving Entity and their respective subsidiaries and Affiliates shall be entitled to rely exclusively and conclusively upon the communications of the Representative relating to the foregoing as the communications, actions and omissions of the Company Members or UAR Holders, as applicable. Neither Pioneer Parent, Pioneer Investment nor the Company (A) are required to make any inquiry or investigation regarding the authority of the Representative to act on behalf of all Company Members and UAR Holders hereunder, or (B) shall be held liable or accountable in any manner for any communications, actions or omission of the Representative in such capacity.

(c) Notwithstanding anything to the contrary contained herein, the Parties acknowledge and agree that (i) the Representative may not enter into or grant any amendments or modifications described in Section 13.1(a)(i) or waivers or consents described in Section 13.1(a)(ii) unless such amendments, modifications, waivers or consents shall affect, as applicable, (A) each Company Member similarly and to the same relative extent and (B) each UAR Holder similarly and to the same relative extent, and (ii) any such amendment, modification, waiver or consent that does not affect any Company Member or UAR Holder, as applicable, similarly and to the same relative extent as it affects other Company Members or UAR Holders, as applicable, must be executed by such Company Member or UAR Holder, as applicable, to be binding on such Company Member or UAR Holder, as applicable. The provisions of this paragraph shall not limit the ability of Pioneer Parent, Pioneer Investment, the Company, the Surviving Entity and their respective subsidiaries and Affiliates to rely exclusively and conclusively upon the communications, actions and omissions of the Representative with respect to the matters provided herein.

(d) The grant of authority provided for in this Section 13.1 (i) is coupled with an interest and is being granted, in part, as an inducement to the Company, Pioneer Parent and Pioneer Investment to enter into this Agreement and shall be irrevocable and survive the death, incompetency, bankruptcy or liquidation of any Company Members or UAR Holders and shall be binding on any successor thereto, and (ii) shall survive any distribution from the Escrow Account. The Pioneer Parties and the Surviving Entity may conclusively and absolutely rely, without inquiry, upon any instruction, decision or action of the Representative in all matters where the Representative is referred to herein or in any Transaction Document, and no Company Member nor any other Person shall have any cause of action against any Pioneer Party or the Surviving Entity (and neither Pioneer Party nor the Surviving Entity shall have any liability) for or relating to any action taken (or omission) in reliance upon instructions, decisions or actions of the Representative. The Representative may resign at any time, subject to the prior appointment of a successor Representative reasonably acceptable to Pioneer Parent or Pioneer Investment; provided, however, that no such resignation shall be effective until a new representative has been appointed by the Company Members and such appointment is effective.

13.2 Compensation; Exculpation; Indemnity.

(a) Except as set forth in any agreement to be entered into among the Representative and certain of the Company Members, the Representative shall not be entitled to any fee, commission or other compensation for the performance of its service hereunder other than a fee of $1,500.00 per month, which amount shall be paid exclusively from the Aggregate Representative Holdback Amount.

(b) In dealing with this Agreement, the Escrow Agreement and any instruments, agreements or documents relating thereto, and in exercising or failing to exercise all or any of the powers conferred upon the Representative hereunder or thereunder, (i) the Representative shall not assume any, and shall incur no, responsibility whatsoever to any Company Member or UAR Holder by reason of any error in judgment or other act or omission performed or omitted hereunder or in connection with this Agreement, the Escrow Agreement or any other Transaction Document, except in the event of liability directly resulting from the Representative’s fraud, gross negligence or willful misconduct and (ii) the Representative shall be entitled to rely on the advice of counsel, public accountants or other independent experts experienced in the matter at issue, and any error in judgment or other act or omission of the Representative pursuant to such advice shall in no event subject the Representative to liability to any Company Member or UAR Holder except in the event of liability directly resulting from the Representative’s gross negligence or willful misconduct. Except as set forth in the previous sentence, in the absence of fraud, gross negligence or willful misconduct, the Representative, in its role as Representative, shall have no liability whatsoever to the Company, Pioneer Parent, Pioneer Investment or any other Person.

(c) Each Company Member and UAR Holder, severally (but not jointly), shall indemnify, defend and hold harmless the Representative, which indemnification shall be paid by such Company Members and UAR Holders in accordance with, as applicable, such Company Member’s or UAR Holder’s Escrow & Holdback Funding Percentage, against all actual losses, penalties, fines, forfeitures, actions, fees, damages, liabilities, claims, obligations, costs and expenses, including reasonable attorneys’, accountants’ and other experts’ fees and all expenses of document location, duplication and shipment and the amount of any judgment against it, of any nature whatsoever (collectively, the “Representative Losses”), arising out of or in connection with the execution or the acts or omissions of the Representative hereunder, or under the other Transaction Documents, in each case as such Representative Loss is suffered or incurred; provided, however, that Representative Losses shall not include special, indirect, punitive or consequential damages of any kind whatsoever (including but not limited to lost profits of the Representative), but excluding special, indirect, punitive or consequential damages of any kind required to be paid to a third party; provided, further, in the event that any such Representative Loss is finally adjudicated to have been primarily caused by the fraud, gross negligence or willful misconduct of the Representative, the Representative will reimburse the Company Members and UAR Holders the amount of such indemnified Representative Loss to the extent attributable to such fraud, gross negligence or willful misconduct. If not paid directly to the Representative by the Company Members and UAR Holders, any such Representative Losses may be recovered by the Representative from (i) the funds in the Aggregate Representative Holdback Amount and (ii) the Aggregate Escrow Amount at such time as remaining amounts would otherwise be distributable to the Company Members and UAR Holders; provided, however, that while this Section 13.2(c) allows the Representative to be paid from the Aggregate Representative Holdback Amount and the Aggregate Escrow Amount, this does not relieve the Company Members and UAR Holders from their obligation to promptly pay such Representative Losses as they are suffered or incurred,

nor does it prevent the Representative from seeking any remedies available to it at law or otherwise. In no event will the Representative be required to advance its own funds on behalf of the Company Members, UAR Holders or otherwise. The foregoing indemnification shall not be deemed exclusive of any other right to which the Representative may be entitled apart from the provisions hereof. In the event of any indemnification under this Section 13.2(c), each Company Member and UAR Holder shall promptly deliver to the Representative full payment of his, her or its portion of the Representative Loss in accordance with his, her or its Escrow & Holdback Funding Percentage.

(d) All of the indemnities, immunities and powers granted to the Representative under this Agreement shall survive the Closing or any termination of this Agreement and the Escrow Agreement, and the foregoing indemnities and immunities will survive the resignation or removal of the Representative.

(e) The Representative Holdback will be used for the purposes of paying directly, or reimbursing the Representative for, any third party expenses pursuant to this Agreement and the Escrow Agreement. Neither the Company Members nor the UAR Holders will receive any interest or earnings on the Representative Holdback and irrevocably transfer and assign to the Representative any ownership right that they may otherwise have had in any such interest or earnings. The Representative will not be liable for any loss of principal of the Representative Holdback other than as a result of its gross negligence or willful misconduct. The Representative shall have the right to withhold funds (and to deposit such funds in the Representative Holdback) that would otherwise be disbursed to the Company Members pursuant to this Agreement as the Representative reasonably determines is necessary to pay directly, or reimburse the Representative for, any third party expenses or other obligations of the Company Members pursuant to this Agreement and the Escrow Agreement; provided, however, that, for all purposes of this Agreement, such amounts shall be treated as having been paid to and received by the Company Members. Contemporaneous with or as soon as practicable following the release in full of the remaining Aggregate Escrow Amount and the termination or expiration of the obligations of the Representative, the Representative shall disburse to the Surviving Entity for further disbursement to the UAR Holders (subject to applicable Tax withholding in accordance with Section 2.15) an amount, with respect to each UAR Holder, equal to the remaining balance of the Aggregate Representative Holdback Amount multiplied by such UAR Holder’s Escrow & Holdback Funding Percentage and shall disburse the balance of the Aggregate Representative Holdback directly to the Company Members, such that each Company Member receives an amount equal to the remaining Aggregate Representative Holdback Amount multiplied by such Company Member’s Escrow & Holdback Funding Percentage. For Tax purposes, the Representative Holdback shall be treated as having been received and voluntarily set aside by the Company Members and the UAR Holders at the time of Closing. The Parties agree that the Representative is not acting as a withholding agent or in any similar capacity in connection with the Aggregate Representative Holdback Amount. If any Tax reporting is required with respect to the ultimate distribution of any balance of the Aggregate Representative Holdback Amount, then the Representative will provide to Pioneer Investment or its designated agent, upon request, information regarding the amounts distributed to each Company Member, to be used by Pioneer Investment or its agent in completing any required Tax reporting. Any portion of the Aggregate Representative Holdback Amount that remains undeliverable or unclaimed after six (6) months of the initial delivery attempt shall

promptly be paid to Pioneer Investment and handled in the same manner as other unclaimed funds as provided in this Agreement.
