take any action or to refrain from taking any action to the extent such Company Party, board of directors, board of managers, or similar governing body believes in good faith, based on advice of counsel, that the taking or failing to take such
action would be inconsistent with applicable Law or its fiduciary obligations under applicable Law, and any such action or inaction pursuant to this Section 8.01 shall not be deemed to constitute a breach of this Agreement; provided,

expression of interest, with such notice to include a copy of such proposal, if it is in writing, or otherwise a summary of the material terms thereof. If the board of directors of the Company Parties decides, in the exercise of its fiduciary

 16 

 8.05. The Company Parties, severally, and not jointly, represents, warrants, and covenants
to each Consenting Stakeholder, as of the date such Consenting Stakeholder executes and delivers this Agreement and as of immediately prior to the Plan Effective Date, that Reorganized Pioneer is not a “covered fund” as such term is
defined in the final regulations promulgated under Section 13 of the U.S. Bank Holding Company Act of 1956, as amended, 12 C.F.R. section 248.10(b)(1) (the “Volcker Rule”). 

Section 9. Transfer of Interests and Securities. 

9.01. During the Agreement Effective Period, no Consenting Stakeholder shall Transfer any ownership (including any beneficial ownership as
defined in the Rule 13d-3 under the Securities Exchange Act of 1934, as amended) in any Company Claims/Interests to any affiliated or unaffiliated party, including any party in which it may hold a direct or
indirect beneficial interest, unless: 
 (a) in the case of any Company Claims/Interests, the authorized transferee is either (1) a
qualified institutional buyer as defined in Rule 144A under the Securities Act, (2) a non-U.S. person in an offshore transaction as defined in Regulation S under the Securities Act, (3) an
institutional accredited investor (as defined in the Rules), or (4) a Consenting Stakeholder; 
 (b) either (i) the transferee
executes and delivers to counsel to the Company Parties, at or before the time of the proposed Transfer, a Transfer Agreement or (ii) the transferee is a Consenting Stakeholder or an affiliate thereof and the transferee provides notice of such
Transfer (including the amount and type of Company Claim/Interest Transferred) to counsel to the Company Parties by the close of business five (5) Business Days following such Transfer; and 

(c) with respect to the Transfer of any Equity Interests only, such Transfer shall not (i) violate the terms of any order entered by the
Bankruptcy Court with respect to preservation of net operating losses or (ii) in the reasonable business judgment of the Company Parties and their legal and tax advisors, adversely affect the Company Parties’ ability to maintain the value
of and utilize the Company Parties’ net operating loss carryforwards or other tax attributes. 
 9.02. Upon compliance with the
requirements of Section 9.01, the transferor shall be deemed to relinquish its rights (and be released from its obligations) under this Agreement to the extent of the rights and obligations in respect of such transferred Company
Claims/Interests. Any Transfer in violation of Section 9.01 shall be void ab initio. 
 9.03. This Agreement shall in no way be
construed to preclude the Consenting Stakeholders from acquiring additional Company Claims/Interests. Notwithstanding the foregoing, (a) such additional Company Claims/Interests shall automatically and immediately upon acquisition by a
Consenting Stakeholder be deemed subject to the terms of this Agreement (regardless of when or whether notice of such acquisition is given to counsel to the Company Parties or counsel to the Consenting Stakeholders) and (b) such Consenting
Stakeholder must provide notice of such acquisition (including the amount and type of Company Claim/Interest acquired) to counsel to the Company Parties within three (3) Business Days of such acquisition. 

  
 17 

 9.04. This Section 9 shall not impose any obligation on any Company Party to issue any
“cleansing letter” or otherwise publicly disclose information for the purpose of enabling a Consenting Stakeholder to Transfer any of its Company Claims/Interests. Notwithstanding anything to the contrary in this Agreement, to the extent a
Company Party and another Party have entered into a Confidentiality Agreement, the terms of such Confidentiality Agreement shall continue to apply and remain in full force and effect according to its terms, and this Agreement does not supersede any
rights or obligations otherwise arising under such Confidentiality Agreements. 
 9.05. Notwithstanding anything herein to the contrary, a
Qualified Marketmaker that acquires any Company Claims/Interests with the purpose and intent of acting as a Qualified Marketmaker for such Company Claims/Interests shall not be required to execute and deliver a Transfer Agreement in respect of such
Company Claims/Interests; provided, however, that (a) such Qualified Marketmaker must Transfer such right, title, or interest by within ten (10) Business Days following its receipt thereof to a transferee that is an entity that
is not an affiliate, affiliated fund, or affiliated entity with a common investment advisor; and (b) any subsequent Transfer by such Qualified Marketmaker of the right, title, or interest in such Claims is to a transferee that is or becomes a
Consenting Stakeholder at the time of such transfer, and (c) such Consenting Stakeholder shall be solely responsible for the Qualified Marketmaker’s failure to comply with the requirements of this Section 9. To
the extent that a Consenting Stakeholder is acting in its capacity as a Qualified Marketmaker, it may Transfer (by purchase, sale, assignment, participation, or otherwise) any right, title, or interests in Company Claims/Interests that the Qualified
Marketmaker acquires from a holder of the Company Claims/Interests who is not a Consenting Stakeholder without the requirement that the transferee be a Permitted Transferee. 

9.06. Notwithstanding anything to the contrary in this Section 9.06, the restrictions on Transfer set forth in this Section 9.06
shall not apply to the grant of any liens or encumbrances on any claims and interests in favor of a bank or broker-dealer holding custody of such claims and interests in the ordinary course of business and which lien or encumbrance is released upon
the Transfer of such claims and interests.

page to this Agreement or a Transfer Agreement, as applicable (as may be updated pursuant to Section 9); 
 (b) it has the full power
and authority to act on behalf of, vote and consent to matters concerning, such Company Claims/Interests; 
 (c) such Company
Claims/Interests are free and clear of any pledge, lien, security interest, charge, claim, equity, option, proxy, voting restriction, right of first refusal, or other limitation on disposition, transfer, or encumbrances of any kind, that would
materially and adversely affect in any way such Consenting Stakeholder’s ability to perform any of its obligations under this Agreement at the time such obligations are required to be performed;

subject only to the express conditions precedent set forth under “Conditions Precedent to the Restructuring” in the Term Sheet and that there are no other implied or express conditions to such purchase and that upon the satisfaction (or

Plan Effective Date, the New Secured Bonds Commitments of the New Secured Bonds Commitment Parties as set forth in this Section 11 shall also terminate. 

Section 12. Mutual Representations, Warranties, and Covenants. Each of the Parties, severally, and not jointly,

further rights, benefits or privileges hereunder and shall have all the rights and remedies that it would have had, had it not entered into this Agreement, and no such rights or remedies shall be

deemed waived pursuant to a claim of laches or estoppel, and shall be entitled to take all actions, whether with respect to the Restructuring Transactions or otherwise, that it would have been
entitled to take had it not entered into this Agreement, including with respect to any and all Claims or Causes of Action; provided, that in no event shall any such termination relieve a Party from liability for its breach or non-performance of its obligations hereunder before the Termination Date.

as prohibiting a Company Party or any of the Consenting Stakeholders from contesting whether any such termination is in accordance with its terms or to seek enforcement of any rights under this Agreement that arose or existed before a Termination
Date. Except as expressly provided in this Agreement, nothing in this Agreement is intended to, or does, in any manner waive, limit, impair, or restrict (a) any right of any Company Party or the ability of any Company Party to protect and
reserve its rights (including rights under this Agreement), remedies, and interests, including its claims against any Consenting Stakeholder, and (b) any right of any Consenting Stakeholder, or the ability of any Consenting Stakeholder, to
protect and preserve its rights (including rights under this Agreement), remedies, and interests, including its claims against any Company Party or any other Consenting Stakeholder. Notwithstanding any provision to the contrary in this
Section 13, no Party may exercise any of its respective termination rights as set forth herein if such Party has failed to perform or comply in all material respects with the terms and conditions of this Agreement (unless
such failure to perform or comply arises as a result of another Party’s actions or inactions), with such failure to perform or comply causing, or resulting in, the occurrence of the applicable termination event giving rise to such termination
right. Nothing in this Section 13.06 shall restrict any Company Party’s right to terminate this Agreement in accordance with Section 13.03(d). 

Section 14. Amendments and Waivers. 

(a) Subject to Section 4, this Agreement may not be modified, amended, or supplemented, and no condition or requirement of this Agreement
may be waived, in any manner except in accordance with this Section 14 and Section 15.18. 
 (b) This Agreement may be modified,
amended, or supplemented in a writing signed by each Company Party and the Required Consenting Noteholders; provided, that amendments to this Section 14 shall require the consent of each Consenting Noteholder.
Notwithstanding the foregoing, (i) if the proposed modification, amendment, waiver, or supplement has an adverse effect on the rights or obligations hereunder or treatment under the Plan of any of the Company Claims/Interests held by a
Consenting Stakeholder, then the consent of each such affected Consenting Stakeholder shall also be required to effectuate such modification, amendment, waiver, or supplement. In the event that the Required Consenting Noteholders and the Company

  
 24 

 
Parties have agreed to any modification, amendment, waiver, or supplement to which any Consenting Stakeholder has refused to consent pursuant to the immediately preceding sentence, then the
Company and the Required Consenting Noteholders may elect to terminate this Agreement as to each such Consenting Stakeholder, and this Agreement shall continue in full force and effect with respect to all other Consenting Stakeholders from time to
time party hereto. 
 (c) Any proposed modification, amendment, waiver, or supplement that does not comply with this Section 14 shall be
ineffective and void ab initio. 
 (d) The waiver by any Party of a breach of any provision of this Agreement shall not operate or be
construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise, and no delay in exercising, any right, power, or remedy under this Agreement shall operate
as a waiver of, any such right, power, or remedy or any provision of this Agreement, nor shall any single or partial exercise of such right, power, or remedy by such Party preclude any other or further exercise of such right, power, or remedy or the
exercise of any other right, power, or remedy. All remedies under this Agreement are cumulative and are not exclusive of any other remedies provided by Law. 

(e) Any waiver, change, modification or amendment to this Agreement and the Term Sheet (including the New Secured Bonds Term Sheet attached

 Any

 15.11. Independent Due Diligence and Decision Making.
Each Consenting Stakeholder confirms that its decision to execute this Agreement has been based upon its independent investigation of the operations, businesses, financial and other conditions, and prospects of the Company Parties. Each Consenting
Stakeholder acknowledges and agrees that it is not relying on any representations or warranties other than as set forth in this Agreement. 

15.12. Enforceability of Agreement. Each of the Parties to the extent enforceable waives any right to assert that the exercise of
termination rights under this Agreement is subject to the automatic stay provisions of the Bankruptcy Code, and expressly stipulates and consents hereunder to the prospective modification of the automatic stay provisions of the Bankruptcy Code for
purposes of exercising termination rights under this Agreement, to the extent the Bankruptcy Court determines that such relief is required. 

15.13. Waiver. If the Restructuring Transactions are not consummated, or if this Agreement is terminated for any reason, the Parties
fully reserve any and all of their rights and nothing herein shall constitute or be deemed to constitute such Party’s consent or approval of any chapter 11 plan of reorganization for the Company Parties or any waiver of any rights such Party
may have under any subordination agreement. Pursuant to Federal Rule of Evidence 408 and any other applicable rules of evidence, this Agreement and all negotiations relating to this Agreement shall not be admissible into evidence in any proceeding
other than a proceeding to enforce its terms or the payment of damages to which a Party may be entitled under this Agreement. 
 15.14.
Specific Performance. It is understood and agreed by the Parties that money damages would be an insufficient remedy for any breach of this Agreement by any Party, and each non-breaching Party shall be
entitled to specific performance and injunctive or other equitable relief (without the posting of any bond and without proof of actual damages) as a remedy of any such breach, including an order of the Bankruptcy Court or other court of competent
jurisdiction requiring any Party to comply promptly with any of its obligations hereunder. 

  
 28 

 15.15. Several, Not Joint, Claims. Except where otherwise specified, the agreements,
representations, warranties, and obligations of the Parties under this Agreement are, in all respects, several and not joint. 
 15.16.
Severability and Construction. If any provision of this Agreement shall be held by a court of competent jurisdiction to be illegal, invalid, or unenforceable, the remaining provisions shall remain in full force and effect if essential terms
and conditions of this Agreement for each Party remain valid, binding, and enforceable. 
 15.17. Relationship Among Consenting
Stakeholders. 
 (a) None of the Consenting Stakeholders shall have any fiduciary duty, any duty of trust or confidence in any form, or
other duties or responsibilities to each other, the Company Parties or their affiliates, or any of the Company Parties’ or their affiliates’ creditors or other stakeholders, including, without limitation, any holders of ABL Claims, Term
Loan Claims, Notes Claims or Company Claims/Interests, and, other than as expressly set forth in this Agreement, there are no commitments among or between the Consenting Stakeholders. It is understood and agreed that any Consenting Stakeholder may
trade in any debt or equity securities of the Company Parties without the consent of the Company Parties or any other Consenting Stakeholder, subject to applicable securities laws and this Agreement (including Section 9 of this Agreement). No
prior history, pattern or practice of sharing confidences among or between any of the Consenting Stakeholders and/or the Company Parties shall in any way affect or negate this understanding and agreement. 

(b) The obligations of each Consenting Stakeholder are several and not joint with the obligations of any other Consenting Stakeholder. Nothing
contained herein and no action taken by any Consenting Stakeholder shall be deemed to constitute the Consenting Stakeholders as a partnership, an association, a joint venture, or any other kind of group or entity, or create a presumption that the
Consenting Stakeholder are in any way acting in concert. The decision of each Consenting Stakeholder to enter into this Agreement has been made by such Consenting Stakeholder independently of any other Consenting Stakeholder. 

(c) The Consenting Stakeholders are not part of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of
the Securities Exchange Act of 1934, as amended or any successor provision), including any group acting for the purpose of acquiring, holding, or disposing of securities (within the meaning of Rule 13d-5(b)(1)
under the Securities Exchange Act of 1934, as amended), with any other Party. For the avoidance of doubt, neither the existence of this Agreement, nor any action that may be taken by a Consenting Stakeholder pursuant to this Agreement, shall be
deemed to constitute or to create a presumption by any of the Parties that the Consenting Stakeholders are in any way acting in concert or as such a “group” within the meaning of Rule 13d-5(b)(1).

  
 29 

 (d) The Company Parties understand that the Consenting Stakeholders are engaged in a wide
range of financial services and businesses, and, in furtherance of the foregoing, the Company Parties acknowledge and agree that the obligations set forth in this Agreement shall only apply to the trading desk(s) and/or business group(s) of the
Consenting Stakeholders that principally manage and/or supervise the Consenting Stakeholder’s investment in the Company Parties, and shall not apply to any other trading desk or business group of the Consenting Stakeholder so long as they are
not acting at the direction or for the benefit of such Consenting Stakeholder. 
 15.18. Email Consents. Where a written consent,
acceptance, approval, or waiver is required pursuant to or contemplated by this Agreement, pursuant to Section 3.02, Section 14, or otherwise, including a written approval by the Company Parties or the Required Consenting Stakeholders,
such written consent, acceptance, approval, or waiver shall be deemed to have occurred if, by agreement between counsel to the Parties submitting and receiving such consent, acceptance, approval, or waiver, it is conveyed in writing (including
electronic mail) between each such counsel without representations or warranties of any kind on behalf of such counsel. 
 15.19.
Settlement Discussions. This Agreement is part of a proposed settlement of matters that could otherwise be the subject of litigation among the Parties. Nothing in this Agreement shall be deemed an admission of any kind. Pursuant to Federal
Rule of Evidence 408, any applicable state rules of evidence and any other applicable law, foreign or domestic, this Agreement, and all negotiations relating thereto shall not be admissible into evidence in any proceeding other than to prove the
existence of this Agreement or in a proceeding to enforce the terms of this Agreement. 
 15.20. Good Faith Cooperation; Further
Assurances. The Parties shall cooperate with each other in good faith and shall coordinate their activities (to the extent reasonably practicable) in respect of all matters concerning the implementation and consummation of the Restructuring
Transactions. Further, each of the Parties shall take such action (including executing and delivering any other agreements and making and filing any required regulatory filings) as may be reasonably necessary to carry out the purposes and intent of
this Agreement. 
 15.21. Acknowledgment. This Agreement is not and shall not be deemed to be a solicitation for consents to the Plan
or an offer of any securities of any of the Company Parties. The acceptance of the Plan by each of the Consenting Stakeholders will not be solicited until such Consenting Stakeholders have received the Disclosure Statement and related ballots in
accordance with applicable non-bankruptcy law (as provided under sections 1125(g) and 1126(b) of the Bankruptcy Code), and will be subject to proper solicitation pursuant to sections 1125, 1126, and 1127 of
the Bankruptcy Code. 
 15.22. Survival of Agreement. Notwithstanding the termination of this Agreement pursuant to Section 13
hereof, the provisions of Sections 5.03, 13.06, and 15 shall survive such termination and shall continue in full force and effect in accordance with the terms hereof; provided, however, that any liability of a Party for failure to comply with
the terms of this Agreement shall survive such termination. 
 15.23. Consenting Term Lenders. Each Consenting Term Lender is
executing this Agreement in its capacity as a lender under the Term Loan Agreement and shall be bound by its terms solely in relation to its Term Loan Claims. Nothing contained herein shall in any way bind any Equity Interests that may be held by
any Consenting Term Lender and/or its affiliates.

	 This term sheet (the “Term Sheet”) summarizes the material terms and conditions of
restructuring and recapitalization transactions (the “Restructuring Transactions”) regarding certain indebtedness of Pioneer Energy Services Corp. (“Pioneer”) and the other Company Parties. The Restructuring
Transactions will be consummated through the prepackaged Plan filed in the Chapter 11 Cases on the terms, and subject to the conditions, set forth in the Restructuring Support Agreement, including this Term Sheet. The regulatory, corporate, tax,
accounting, and other legal and financial matters related to the Restructuring Transactions have not been fully evaluated, and any such evaluation may affect the terms and structure of any Restructuring Transactions.

 
 This Term Sheet does not constitute (nor shall it be construed as)
an offer with respect to any securities or a solicitation of acceptances or rejections as to any chapter 11 plan, it being understood that such a solicitation, if any, only will be made in compliance with applicable provisions of securities,
bankruptcy, and/or other applicable laws. This Term Sheet does not address all terms that would be required in connection with any potential restructuring and is subject to the negotiation, execution, and delivery of definitive documentation in
accordance with the Restructuring Support Agreement.
  

	 Capitalized terms used but not initially defined in this Term Sheet shall have the meaning hereinafter
ascribed to such terms, or if not defined in this Term Sheet, such terms shall have the meaning ascribed to such terms in the Restructuring Support Agreement.
  

	Restructuring Summary
		
	Overview	  	 The Company Parties will implement the Restructuring Transactions in accordance with the restructuring support agreement to which this Term
Sheet is attached (together with the exhibits and schedules attached to such agreement, each as may be amended, restated, supplemented, or otherwise modified from time to time in accordance with the terms thereof, the “Restructuring
Support Agreement”), which shall be entered into by the Company Parties and the Consenting Stakeholders. This Term Sheet is attached to and made a part of the Restructuring Support Agreement.

 

	Transaction Summary	  	 The Restructuring Transactions shall include the following transactions, among others, as set forth in further detail in this Term Sheet:

 
 •  Pioneer will conduct a rights
offering (the “Rights Offering”) pursuant to the Rights Offering Documents (as defined below) to issue (a) New Convertible Bonds up to the aggregate principal amount of $123,205,000.00 (the “Rights Offering Convertible
Bonds”) (which, for the avoidance of doubt, is exclusive of both the Premium Convertible Bonds (as defined below), on terms consistent in all material respects with those set forth in the term sheet attached as Exhibit A (the
“Convertible Bonds Term Sheet”), and the $1,795,000.00 New Convertible Bonds to be purchased separately by

			
		  	 the Management Commitment Parties (as defined below) (the “Management Commitment Convertible Bonds”) issued pursuant to the
Backstop Commitment Agreement) and (b) up to 9,240,375 shares of Stapled Special Voting Stock1 (the “Rights Offering Stapled Special Voting Stock”) (which, for the avoidance
of doubt, is exclusive of both the Premium Stapled Special Voting Stock (as defined below) and the 134,625 shares of Stapled Special Voting Stock to be issued separately to the Management Commitment Parties (the “Management Commitment
Stapled Special Voting Stock”) pursuant to which (i) each eligible holder of Notes Claims will be offered the right to purchase up to its pro rata share of Rights Offering Convertible Bonds (together with the corresponding
Rights Offering Stapled Special Voting Stock) for aggregate consideration of $116,121,000.00 in cash; and (ii) each eligible holder of the issued and outstanding common stock of Pioneer (or any option, warrant, or right, contractual or
otherwise, to acquire, sell or subscribe for such common stock, including any restricted stock unit), that has vested or will vest on or prior to the Plan Effective Date (“Existing Equity Interests”), will be offered the right to
purchase up to its pro rata share of Rights Offering Convertible Bonds (together with the corresponding Rights Offering Stapled Special Voting Stock) for aggregate consideration of $7,084,000.00 in cash. The proceeds of the Rights Offering
will be used by Pioneer (i) to pay the Restructuring Expenses (as defined below), (ii) to fund Plan distributions, case administration expenses, and exit costs (including, without limitation, a portion of the payment in full in cash of the Term
Loan Claims), and (iii) for general corporate purposes. The terms of the Rights Offering will be in accordance with the Rights Offering Documents and otherwise acceptable to the Company Parties and the Backstop Parties (as defined in the
Backstop Commitment Agreement), and reasonably acceptable to the Required Consenting Noteholders.
  

•  The Q419 payment under the Company Incentive Plan (the “Q4 CIP Payment”) will be
paid in cash prior to the Petition Date. The top 4 recipients shall commit to invest the after-tax amounts of such payment in Management Commitment Convertible Bonds pursuant to the Backstop Commitment
Agreement. Each of the remaining recipients of the Q4 CIP Payment will have the option to reinvest up to the amount of such recipient’s portion of the Q4 CIP Payment in the Management Commitment Convertible Bonds by becoming parties to the
Backstop Commitment Agreement. For the avoidance of doubt, the Q4 CIP Payment recipients who invest their after-tax amounts of such payment will become Management Commitment Parties and the New Convertible
Bonds to be purchased thereby are part of the Management Commitment Convertible Bonds.

Sheet”) and otherwise acceptable to the Company Parties, the Required New Secured Bondholders (as defined in the New Secured Bonds Term Sheet) and the Required Consenting Noteholders.

Noteholders.

SUMMARY OF TERMS AND CONDITIONS 

 
  

This Summary of Terms and Conditions (this “Term Sheet”) is not a complete list of all material terms and conditions of the potential
transaction described herein. This Term Sheet shall not constitute (nor shall it be construed as) an offer or a legally binding obligation to buy or sell, or a solicitation of an offer to buy or sell, any of the securities referred to herein, it
being understood that such an offer or solicitation, if any, only will be made in compliance with applicable provisions of securities and/or other applicable laws. The proposal below has been provided for illustrative purposes. 

Capitalized terms used in this Term Sheet but not defined herein shall have the meanings set forth in the Restructuring Support Agreement. 

 

			
	General Terms
		
	Issuer:	  	Pioneer Energy Services Corp.
		
	Security:	  	5% Convertible Senior Unsecured Bonds (the “New Convertible Bonds”)
		
	Amount:	  	Up to $134,584,000.00 in aggregate principal amount, consisting of up to $125,000,000.00 in initial principal amount (the “Initial Principal Amount”), including up to $123,205,000.00 aggregate principal amount of
Rights Offering Convertible Bonds, $1,795,000.00 aggregate principal amount of Management Commitment Convertible Bonds, and up to $9,584,000.00 aggregate principal amount of Premium Convertible Bonds.
		
	Interest:	  	The New Convertible Bonds will bear interest at a fixed rate of 5% per annum, which will be payable semi-annually in-kind in the form of an increase to the principal amount
(“PIK”).
		
	Initial Principal Amount:	  	$1,000 per New Convertible Bond.
		
	Trustee:	  	To be agreed by the Company Parties, the Required Commitment Parties (as defined in the Backstop Commitment Agreement) and the Required Consenting Noteholders.
		
	Use of Proceeds	  	The proceeds of the New Convertible Bonds shall be used to (i) pay the Restructuring Expenses, (ii) fund Plan distributions (including the cash distribution to holders of Term Loan Claims pursuant to the Plan), case
administration expenses, and exit costs, and (iii) for general corporate purposes.
	
	Maturity, Conversion and Redemption
		
	Maturity Date:	  	Five years and six months from issuance.

			
	Conversion:	  	 The New Convertible Bonds will be convertible at any time in whole or in part at the option of the holder thereof, and mandatorily on the
Maturity Date, into, per $1,000 principal amount of New Convertible Bonds, at the Issuer’s option, a number of shares of the Issuer’s common stock, $0.10 par value per share (the “Common Stock”), equal to the then-current
Conversion Rate or the cash value of such number of shares of Common Stock (the “Conversion Consideration”). The New Convertible Bonds will also be convertible in the same manner, at the option of the Issuer, as set forth under
“Issuer Conversion Right.”
  
 Notwithstanding the above, if the value of the
Conversion Consideration otherwise deliverable in connection with a mandatory conversion of a New Convertible Bond on the Maturity Date would be less than the principal amount of such New Convertible Bond, plus accrued and unpaid interest, then the
New Convertible Bond will instead convert into an amount of cash equal to principal plus accrued and unpaid interest.

		
	Conversion Rate:	  	751 shares of Common Stock per $1,000 principal amount of New Convertible Bonds (approximately equal to $1,000 divided by the Conversion Price), subject to adjustment as

	Conversion Price:	  	$13.33 per share of Common Stock.
		
	Antidilution Protection:	  	 The Conversion Rate will be subject to customary adjustments for convertible debt securities, but with no adjustment for any dividends. There
will be an adjustment to the Conversion Rate for any issuance of Common Stock (or rights, options, warrants or convertible or exchangeable securities) at effective prices below the Conversion Price.

 
 With respect to any dividends on the Common Stock (including distributions in
liquidation), each holder of a New Convertible Bond will receive, for each $1,000 principal amount of New Convertible Bonds, at the same time and on the same terms as holders of the Common Stock, the amount of cash or other property that such holder
would have received if such holder held a number of shares of Common Stock equal to the Conversion Rate.

  
  

	1 	 The Conversion Price and Conversion Rate will be determined by the Company Parties and the Required Commitment
Parties prior to the Plan Effective Date so that as of the Plan Effective Date the New Convertible Bonds in the aggregate will be convertible into 90.00%-93.61% of the Issuer’s common stock, on a
post-conversion basis, subject to dilution on account of the Employee Incentive Plan; provided, that the low end of the range assumes that the Rights Offering Convertible Bonds are issued only with respect to the $118,013,000.00 backstopped
by the Backstop Parties (the “Backstop Amount”) and the high end of the range assumes that the Rights Offering is fully subscribed.

Convertible Bonds for a purchase price equal to 100% of principal plus accrued and unpaid interest.
		
	Issuer Conversion Right:	  	The Issuer, at its option, may cause the conversion of all or part of the New Convertible Bonds into, per $1,000 principal amount of New Convertible Bonds, a number of shares of Common Stock equal to the then-current Conversion Rate
(as adjusted as described above under “Conversion Rate”) or the cash value of such number of shares of Common Stock, upon the consummation of any Merger Event.
		
	Merger Event:	  	Customary for convertible debt securities of companies of a similar size, and to include in any event (i) acquisitions of beneficial ownership of more than 50% of the voting power of the outstanding Common Stock, any sales or
dispositions of all or substantially all of the assets of the Issuer on a consolidated basis, or any merger, consolidation, recapitalization or similar transaction where the Common Stock is converted into, or exchanged for, any other consideration
(“Reference Property”), (ii) any one or more (A) bona fide consolidations, amalgamations, mergers or binding share exchanges of the Issuer or any of its subsidiaries with or into another entity in which the Issuer is the
continuing entity and which does not result in a reclassification or change of all of the Common Stock outstanding, and (B) acquisitions by the Issuer or any of its subsidiaries of substantially all assets, or a business, division, or line of
business, of any entity, for which, in the case of this clause (ii), either (x) the equity value of the person or persons being acquired is, in the aggregate for all such transactions, greater than $100 million, or (y) such
transactions have been approved by holders of a majority of the outstanding principal amount of the New Convertible Bonds.
		
	Other Terms

 Accordingly, Pioneer hereby represents, warrants and covenants that all written information and data

shall be, prepared in good faith on the basis of information and assumptions that are believed by you to be reasonable at the time such projections, Approved Budget or updated, modified or supplemented budget(s) were prepared; it being recognized by
PNC that projections of future results and forecasted budgets are not to be viewed as facts and actual results may vary significantly from projected results. In arranging and syndicating the Facilities, PNC will be using and relying on the
Information without independent verification thereof.

 This Commitment Letter shall be governed by, and
construed in accordance with, the law of the State of New York. This Commitment Letter sets forth the entire agreement between the parties with respect to the matters addressed herein and supersedes all prior communications, written or oral, with
respect hereto. This Commitment Letter may be executed in any number of counterparts, each of which, when so executed, shall be deemed to be an original and all of which, taken together, shall constitute one and the same Commitment Letter. Delivery
of an executed counterpart of a signature page to this Commitment Letter by telecopier shall be as effective as delivery of an original, executed counterpart of this Commitment Letter.

Letter, the Term Sheets, any of the Transactions, or any other instrument, document or agreement executed or delivered in connection herewith, whether sounding in contract, tort or otherwise. 

To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to
obtain, verify, and record information that identifies each customer, including organizations and businesses that opens an account. What this means for you: When you open an account, we will ask for your name, address, taxpayer identifying number
and other information that will allow us to identify you, such as articles in incorporation. For some businesses and organizations, we may also need to ask for identifying information and documentation relating to certain individuals associated with
the business or organization.

		  	Interest will be calculated on the daily outstandings on a 360 day year for the actual number of days elapsed and will be due monthly in arrears on the first business day of each month for Base Rate borrowings and on the last day of
each interest period for LIBOR Rate borrowings.
		
		  	The “Base Rate” shall mean, for any day, a fluctuating per annum rate of interest equal to the highest of (i) the interest rate per annum announced from time to time by the Agent at its principal office as its

		  	LIBOR Rate pricing will be subject to customary adjustments for statutory reserves.

Credit Facility, or a counterparty satisfactory to the Agent, enabling the DIP Borrowers to protect themselves against fluctuations in interest rates with respect to a mutually agreed amount of initial and projected outstanding advances under DIP
Credit Facility with a final termination date no later than the DIP Maturity Date. The DIP Borrowers’ obligations under any Hedge Agreement entered into with Agent, Lender or any affiliate of either in accordance with the preceding sentence
will be secured by the DIP Collateral, and benefit from the guarantees of the Guarantors, in each case on a pari passu basis with the DIP Borrowers’ obligations under the DIP Credit Facility.
		
	Letter of Credit Fees:	  	The DIP Borrowers shall pay Letter of Credit fees at a per annum rate equal to the DIP LIBOR Rate Margin on the aggregate face amount of the Letters of Credit issued under the DIP Credit Facility. In addition, the DIP Borrowers
shall pay a Letter of Credit fronting fee of 0.25% per annum to PNC as the fronting bank, payable quarterly in arrears.

	Priority and Security:	  	The DIP Credit Facility, any Hedge Agreements, and any cash management products and services provided by the Agent or any Lender or any direct or indirect Subsidiary or affiliate of Agent or any Lender will be secured by:
		
		  	 (i) continuing, valid, binding, enforceable,
non-avoidable, and automatically and properly perfected postpetition security interests in and liens in all of the “DIP Collateral”, which “DIP Collateral” includes all real and personal
property of the Debtors and their bankruptcy estates, whether now existing or hereafter arising, tangible or intangible, of each of the Debtors, specifically including all commercial tort claims that may be brought by the Debtors and the proceeds of
any actions brought under chapter 5 of the Bankruptcy Code (such security interests and liens, the “DIP Liens”), which liens shall be senior in priority and superior to any security, mortgage, collateral interest, lien, claim
or interest of any other person, subject only to the professional fee carve-out to be agreed (the “Carve-Out”), the liens (whether pre-petition liens or adequate protection liens) on the Term Priority Collateral (as defined in the Intercreditor Agreement dated as of November 8, 2017 (the “Existing Intercreditor
Agreement”), by and among Pioneer, the lenders party thereto, and Wilmington Trust, National Association, as administrative agent) in favor of the secured parties under the existing term loan facility evidenced by that certain Term Loan
Agreement dated as of November 8, 2017 (such facility, the “Existing Term Loan Facility”), by and among Pioneer, the lenders party thereto, and Wilmington Trust, National Association, as administrative agent (such liens, the

Liens on the Term Priority Collateral;

received in such lockbox or blocked account(s) (save and except for any Term Priority Collateral or any proceeds thereof) shall be applied to pay all outstanding obligations under the DIP Credit Facility, during a Cash Dominion Period. For the
purpose of crediting the DIP Borrowers’ loan account and calculating interest, all items of payment shall be deemed applied by Agent two (2) business days following the business day of Agent’s receipt thereof. To facilitate such cash
dominion, the DIP Borrowers shall establish at least one concentration blocked account with Agent into which all remittances and other proceeds of the DIP Collateral (save and except for any Term Priority Collateral or any proceeds thereof)
deposited into or made to any other lockbox or blocked accounts maintained with a bank or other financial institution other than Agent shall be swept on a daily basis and, during a Cash Dominion Period, following receipt of such funds into such

consecutive days.

disbursements of outside counsel (provided that Credit Parties shall not be required to reimburse the legal fees and expenses of more than one counsel to the Agent and the Lenders (in addition to any reasonably necessary local counsel in each

the account of the Credit Parties and payable on demand.

WHEREAS, in order to facilitate the Plan and the Rights Offering, pursuant to this Agreement, and subject to the terms, conditions and

 NOW, THEREFORE, in
consideration of the foregoing, and the representations, warranties and covenants set forth herein, and other good and valuable consideration, the Company and the Commitment Parties agree as follows:

“Eligible Noteholder”) during the Rights Exercise Period will receive the rights (the “Subscription Rights”) with respect to the Notes Claims held by such Eligible Holder as of such time (such claims being
“Eligible Claims”) to subscribe for its pro rata share (measured as the amount of Eligible Claims held by such Eligible Noteholder (for the avoidance of doubt, after taking into account transfers of such Eligible Claims after
the Subscription Commencement Date) as compared to the aggregate amount of Notes Claims held by all holders of Notes Claims) of the Eligible Noteholder Initial Principal Amount of Rights Offering Securities. Pursuant to the RSA and the Plan, each
holder of Existing Equity Interests (as defined in the Term Sheet) that is either (i) an “accredited investor” as defined in Rule 501(a) under the Securities Act or (ii) a “qualified institutional buyer” as defined in
Rule 144A under the Securities Act and makes certain other customary representations and warranties (each such holder, an “Eligible Equity Holder”, and together with an Eligible Noteholder, “Eligible Holders”)
during the Rights Exercise Period will receive Subscription Rights to subscribe for its pro rata share (measured as the number of shares represented by the Existing Equity Interests held by such Eligible Equity Holder (for the avoidance of
doubt, after taking into account transfers of such Existing Equity Interests after the Subscription Commencement Date) as compared to the aggregate number of shares represented by the Existing Equity Interests held by all holders of Existing Equity
Interests) of the Eligible Equity Holder Initial Principal Amount of Rights Offering Securities. 

  
 3 

 (b) Subject to the terms and conditions of this Agreement, the Company hereby undertakes to
cause the Issuer to offer Rights Offering Securities for subscription by Eligible Holders of Eligible Claims pursuant to the RSA and the Plan as set forth in this Agreement. 

(c) The Company will cause the Issuer to issue Subscription Rights to purchase the Rights Offering Securities. Each Eligible Noteholder holding
Eligible Claims during the Rights Exercise Period will receive a Subscription Right to subscribe for its pro rata share of the Eligible Noteholder Initial Principal Amount of Rights Offering Securities. Each Eligible Equity Holder holding
Existing Equity Interests during the Rights Exercise Period will receive a Subscription Right to subscribe for its pro rata share of the Eligible Equity Holder Initial Principal Amount of Rights Offering Securities. 

(d) (1) Following the Petition Date, the Company will provide, or cause to be provided, to each Eligible Holder of Eligible Claims or Existing
Equity Interests a subscription form (the “Rights Offering Subscription Form”), whereby each Eligible Holder of Eligible Claims or Existing Equity Interests may exercise its Subscription Rights in whole or in part, provided
that such Eligible Holder of Eligible Claims or Existing Equity Interests (i) timely and properly executes and delivers its Rights Offering Subscription Form (with accompanying IRS Form W-9 or appropriate
IRS Form W-8, as applicable), and for transferees only, a transfer notice included as an exhibit to the Rights Offering Subscription Form, to the subscription agent for the Rights Offering selected by the
Company (the “Subscription Agent”) in advance of the Subscription Instruction Deadline and (ii) delivers the securities underlying its Eligible Claims or Existing Equity Interests through The Depository Trust Company Automated
Tender Offer Program in advance of the Subscription Instruction Deadline and (A) if such Eligible Holder is not a Backstop Party, the aggregate purchase price of the Rights Offering Securities elected to be purchased by the Eligible Holder of
Eligible Claims shall be paid in accordance with the Rights Offering Procedures or (B) if such Eligible Holder is a Backstop Party, such Backstop Party pays the aggregate purchase price of its Rights Offering Securities in accordance with
Section 1(g). 
 (2) In advance of the Subscription Instruction Deadline, each Backstop Party shall timely and properly exercise its
rights to purchase its allocated portion of the Rights Offering Securities (subject to its Backstop Cap), pursuant to the procedures set forth in the preceding clause (1) and the Rights Offering Procedures, subject to payment in accordance with
Section 1(g). For the avoidance of doubt, each Backstop Party shall fully exercise all Subscription Rights allotted to it for the purchase of the Rights Offering Securities, subject to its Backstop Cap. 

  
 4 

 (3) For purposes of this Agreement, the “Subscription Instruction Deadline”
means 5:00 p.m. New York City time on such date that is specified in the Rights Offering Procedures or such other date as the Company, subject to the approval of the Required Commitment Parties, may specify in a notice provided to the Eligible
Holders of Eligible Claims before 9:00 a.m. New York City time on the Business Day before the then-effective Subscription Instruction Deadline. For purposes of this Agreement, “Business Day” means any day of the year on which
national banking institutions in New York City are open to the public for conducting business and are not required or authorized to close. 

(e) The Company will cause the Issuer to issue the Rights Offering Securities to the Eligible Holders of Eligible Claims or Existing Equity
Interests with respect to which Subscription Rights were validly exercised by such Eligible Holders of Eligible Claims or Existing Equity Interests upon the Plan Effective Date. The portion of Rights Offering Securities issued to an Eligible Holder
who elects to acquire such Rights Offering Securities shall be rounded down to the nearest security. 
 (f) If the Subscription Agent for any
reason does not receive from an Eligible Holder of Eligible Claims or Existing Equity Interests each of (i) a timely and duly completed Rights Offering Subscription Form, (ii) timely tender of the securities underlying its Eligible Claims
or Existing Equity Interests and (iii) timely payment for the Rights Offering Securities being purchased by such Eligible Holder of Eligible Claims or Existing Equity Interests, the Rights Offering Procedures shall provide that, unless
otherwise approved by the Company and the Required Commitment Parties, such Eligible Holder of Eligible Claims or Existing Equity Interests shall be deemed to have relinquished and waived its right to participate in the Rights Offering. 

(g) No later than five (5) Business Days following the Subscription Instruction Deadline, the Company hereby agrees and undertakes to
deliver to each Backstop Party by email delivery a written notice (the “Funding Notice”) of (i) the number of Rights Offering Securities that such Backstop Party has subscribed to purchase pursuant to such Backstop Party’s

Amount”, and such number of Unsubscribed Securities, the “Backstop Securities”); (iv) wire instructions for a segregated bank account of the Subscription Agent to which such Backstop Party shall deliver an amount equal to
its Funding Amount; and (v) the estimated deadline for delivery of the Funding Amount, which shall be the Plan Effective Date for each Backstop Party (the “Backstop Funding Deadline”). No later than the Backstop Funding
Deadline, each Backstop Party shall deliver and pay its applicable Funding Amount by wire transfer in immediately available funds in U.S. dollars to the segregated bank account of the Subscription Agent designated by the Subscription Agent in the

accrued thereon, promptly following such termination.

the Commitment Parties may enforce all of their respective rights and remedies hereunder and under applicable law, including the right to seek money damages (including setoff of any Plan recovery) and/or specific performance upon the failure to
timely fund by the Defaulting Commitment Party. Each of the non-defaulting Backstop Parties shall have the right, but not the obligation, to assume its pro rata share of such Defaulting Commitment

Party’s Commitment. If a Defaulting Commitment Party does not cure its failure to fund its Commitment within two (2) days after receiving notice of such failure from the Company, such Commitment Party shall not be entitled to any portion
of the Backstop Commitment Premium or Management Commitment Premium, as applicable.

Section 6. REPRESENTATIONS AND WARRANTIES OF THE
COMMITMENT PARTIES. Each of the Commitment Parties severally and not jointly represents and warrants to the Company as set forth below. Each representation, warranty and agreement is made as of the date hereof.

effective registration statement under the Securities Act of 1933 and the rules and regulations of the SEC thereunder (the “Securities Act”) or in a transaction exempt from or not subject to registration under the Securities Act and
any applicable state securities laws. 

  
 18 

 (e) Purchase Intent. Such Commitment Party is acquiring the Commitment Party
Securities for its own account or for the accounts for which it is acting as investment advisors or manager, and not with a view to distributing or reselling such Commitment Party Securities or any part thereof. Such Commitment Party understands
that such Commitment Party must bear the economic risk of this investment indefinitely, unless the Commitment Party Securities are registered pursuant to the Securities Act and any applicable state securities or “blue sky” Laws or an
exemption from such registration is available, and further understands that it is not currently contemplated that any Commitment Party Securities will be registered at the time of issuance. 

(f) Investor Status. Such Commitment Party is either (i) an “accredited investor” as defined in Rule 501(a) under the

Such Commitment Party understands and accepts that its investment in the Commitment Party Securities involves risks. Such Commitment Party has received such documentation as it has deemed necessary to make an informed investment decision in
connection with its investment in the Commitment Party Securities, has had adequate time to review such documents prior to making its decision to invest, has had a full opportunity to ask questions of and receive answers from the Issuer or any
person or persons acting on behalf of the Issuer concerning the terms and conditions of an investment in the Issuer and has made an independent decision to invest in the Commitment Party Securities based upon the foregoing and other information
available to it, which it has deemed adequate for this purpose. With the assistance of each Commitment Party’s own professional advisors, to the extent that such Commitment Party has deemed appropriate, such Commitment Party has made its own
legal, tax, accounting and financial evaluation of the merits and risks of an investment in the Commitment Party Securities. Such Commitment Party understands and is able to bear any economic risks associated with such investment (including the
necessity of holding such securities for an indefinite period of time). Except for the representations and warranties expressly set forth in this Agreement or any other transaction agreement, such Commitment Party has independently evaluated the
merits and risks of its decision to enter into this Agreement and disclaims reliance on any representations or warranties, either express or implied, by or on behalf of the Company or the Issuer. Notwithstanding the foregoing or any other provision
of this Agreement, nothing in this Section 6(g) shall constitute a waiver of claims of fraud.

Agreement with applicable state filing agencies, (iv) such consents, approvals, authorizations, registrations or qualifications as may be required under foreign securities laws, federal securities laws or state securities or “blue
sky” Laws in connection with the offer and sale of the Rights Offering Securities, Unsubscribed Securities and the Backstop Commitment Premium and (v) such consents, approvals, authorizations, registrations or qualifications the absence of
which would not, individually or in the aggregate, reasonably be expected to result in a material adverse effect on the ability of such Commitment Party to perform its obligations under this Agreement. 

(i) Sufficiency of Funds. Such Commitment Party will have sufficient immediately available funds to make and complete the payment of the
aggregate purchase price for its applicable Commitment on the Plan Effective Date or the Management Funding Deadline, as applicable. 
 (j)
No Brokers Fee. Such Commitment Party is not a party to any contract with any Person that would give rise to a valid claim against any of the Debtors for a brokerage commission, finder’s fee or like payment in connection with the Rights
Offering or the sale of the Rights Offering Securities, the Unsubscribed Securities or the Management Commitment Securities.

 “THIS SECURITY [AND THE
COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE] [HAS] NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
 (1)
REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT,
AND 
 (2) AGREES FOR THE BENEFIT OF [PIONEER ENERGY SERVICES CORP.] (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR
OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE APPLICABLE RESALE RESTRICTION TERMINATION DATE, EXCEPT: 

  
 21 

 (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND
APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.” 

In the event that any such securities are uncertificated, such securities shall be subject to a restrictive notation substantially similar to
the Legend in the stock ledger or other appropriate records maintained by the Issuer or agent, and the term “Legend” shall include such restrictive notation. The Issuer shall remove the Legend (or restrictive notation, as applicable) set
forth above from the certificates evidencing any such securities (or the share register or other appropriate Issuer records, in the case of uncertified securities), upon request, at any time after the restrictions described in such Legend cease to
be applicable, including, as applicable, when such securities may be sold under Rule 144 of the Securities Act without conditions. The Issuer may reasonably request such opinions, certificates or other evidence that such restrictions no longer apply
as a condition to removing the Legend. 
 (f) Unsubscribed Securities. The Company, in consultation with counsel for the Backstop
Parties, shall determine the amount of Unsubscribed Securities, if any, and, in good faith, provide a Funding Notice that accurately reflects the amount of Unsubscribed Securities as so determined and to provide to the Backstop Parties a
certification by the Subscription Agent of the Unsubscribed Securities or, if such certification is not available, such written backup to the determination of the Unsubscribed Securities as the Backstop Parties may reasonably request.

consent of the Required Commitment Parties, during the period from the date of this Agreement to the earlier of the Plan Effective Date and the date on which this Agreement is terminated in accordance with its terms, the Company shall use, and shall
cause its subsidiaries to use, commercially reasonable efforts to reasonably promptly take all actions and prepare and file all necessary documentation (including by reasonably cooperating with the Backstop Parties as to the appropriate time of
filing such documentation and its content) and to effect all applications that are reasonably necessary or advisable in connection with seeking any governmental approval, exemption or authorization from any governmental authority, including under
any Antitrust Laws, that are reasonably necessary to consummate and make effective the transactions contemplated by this Agreement. To the extent permitted by applicable law, the Company and each of its subsidiaries shall reasonably promptly notify
the Backstop Parties (and furnish to them copies of, if requested) of any communications from any antitrust or other regulatory authority and shall not participate in any meeting with any such antitrust or regulatory authority unless they consult
with the Backstop Parties in advance to the extent permitted by applicable law and give the Backstop Parties a reasonable opportunity to attend and participate thereat. The Company and each of its subsidiaries shall not take any action that is
intended or would reasonably be expected to materially impede or delay the ability of the parties hereto to obtain any necessary approvals required for the transactions contemplated by this Agreement. For purposes of this Agreement,
“Antitrust Laws” means the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”) and any similar law enforced by any governmental
antitrust entity of any jurisdiction regarding pre-acquisition notifications for the purpose of competition reviews of mergers and acquisitions, the Sherman Act, as amended, the Clayton Act, as amended, the

and records and (ii) during such period, furnish promptly to such parties all reasonable information concerning the Company and its subsidiaries’ business, properties and personnel as may reasonably be requested by any such party,

or the board of directors, board of managers, or similar governing body of any of them, in such person’s capacity as a director, officer, or member of the Company or any of its subsidiaries, to take any action or to refrain from taking any
action to the extent the Company, such subsidiary, or such board of directors, board of managers, or similar governing body believes in good faith, based on advice of counsel, that the taking or failing to take such action would be inconsistent with
applicable law or its fiduciary obligations under applicable law, and any such action or inaction pursuant to this Section 7(m)(2) shall not be deemed to constitute a breach of this Agreement; provided, however, that nothing in

be formed by such other entity, in each case while preserving to the maximum extent possible all other provisions of this Agreement.

(i) any Backstop Party shall have breached any representation, warranty, covenant or other agreement made by such Backstop

announcement that they intend to pursue a Superior Proposal or (ii) enter into a definitive agreement with respect to a Superior Proposal; 

(ix) the filing by the Company of any Definitive Document (as defined in the RSA), amendments, modifications or supplements

the Required Commitment Parties; 
 (x) any of the following shall have occurred: (i) the Company and its subsidiaries

 (xv) the Company or any of its subsidiaries enters
into a definitive agreement with respect to an Alternative Restructuring Proposal;

“Termination Date”), this Agreement shall be of no further force and effect as to such Party and each Party subject to such termination shall be immediately released from its or their respective liabilities, obligations,
commitments, undertakings, and agreements under or related to this Agreement, shall have no further rights, benefits or privileges hereunder and shall have all the rights and remedies that it would have had, had it not entered into this Agreement,
and no such rights or remedies shall be deemed waived pursuant to a claim of laches or estoppel, and shall be entitled to take all actions, whether with respect to the Restructuring Transactions or otherwise, that it would have been entitled to take
had it not entered into this Agreement, including with respect to any and all Claims (as defined in the RSA) or Causes of Action (as defined in the RSA); provided, that in no event shall

  
 34 

 
any such termination relieve a Party from liability for its breach or non-performance of its obligations hereunder before the Termination Date. Nothing in
this Agreement shall be construed as prohibiting the Company, any of its subsidiaries or any of the Backstop Parties from contesting whether any such termination is in accordance with its terms or to seek enforcement of any rights under this
Agreement that arose or existed before a Termination Date. Except as expressly provided in this Agreement, nothing in this Agreement is intended to, or does, in any manner waive, limit, impair, or restrict (a) any right of the Company or the
ability of the Company to protect and reserve its rights (including rights under this Agreement), remedies, and interests, including its claims against any Backstop Party, and (b) any right of any Backstop Party, or the ability of any Backstop
Party, to protect and preserve its rights (including rights under this Agreement), remedies, and interests, including its claims against the Company or any other Backstop Party. Notwithstanding any provision to the contrary in this Section 14,
no Party may exercise any of its respective termination rights as set forth herein if such Party has failed to perform or comply in all material respects with the terms and conditions of this Agreement (unless such failure to perform or comply
arises as a result of another Party’s actions or inactions), with such failure to perform or comply causing, or resulting in, the occurrence of the applicable termination event giving rise to such termination right. Nothing in this
Section 14(d) shall restrict the right of the Company or any of its subsidiaries to terminate this Agreement in accordance with Section 14(b)(ii). 

(e) Termination Fee. To the extent this Agreement is validly terminated in accordance with this Section 14 (other than
Section 14(b)(i) or Section 14(c)(iv)), the Company shall, within three (3) Business Days of such termination, pay or cause to be paid to the Commitment Parties that are not Defaulting Commitment Parties a non-refundable cash payment in an aggregate amount equal to (x) $9,440,000 payable to the Backstop Parties that are not Defaulting Commitment Parties, allocated pro rata based on each such Backstop
Party’s Backstop Commitment Percentage (excluding the Backstop Commitment Percentage of any Defaulting Commitment Party), plus (y) $143,000 payable to the Management Commitment Parties that are not Defaulting Commitment Parties, allocated
pro rata based on each such Management Commitment Party’s percentage (its “Management Commitment Percentage”), as set forth on Schedule 1 opposite such Management Commitment Party’s name (excluding the
Management Commitment Percentage of any Defaulting Commitment Party); provided that in the event that (1) this Agreement is validly terminated in accordance with Section 14(c)(xviii) because the RSA was validly terminated in
accordance with Section 13.03(a) of the RSA or (2) this Agreement is validly terminated in accordance with Section 14(a)(ii) or Section 14(a)(iii) due to a failure of a condition to closing set forth in Section 11 of this
Agreement to be satisfied by the Outside Date and (w) such failure is a result of the breach of the RSA by a Consenting Noteholder(s) (as defined in the RSA), (x) the Company has given notice of such breach to such Consenting Noteholder(s), (y)
within ten (10) Business Days following the giving of such notice, either such Consenting Noteholder(s) have failed to cure such breach or this Agreement has been terminated in accordance with Section 14(a)(ii), and (z) such ten
(10) Business Day period has elapsed prior to such termination pursuant to Section 14(c)(xviii) or Section 14(a)(iii), then any such breaching Consenting Noteholder who is also a Commitment Party hereunder shall not be entitled to
their pro rata share of any payment to be paid to the Commitment 

  
 35 

 
Parties pursuant to this Section. To the extent that all amounts due pursuant to this Section 14(e) shall have been paid by the Company or the applicable Commitment Parties in
connection with a termination of this Agreement, the Commitment Parties shall not have any additional recourse against the Company for any obligations or liabilities relating to or arising from this Agreement. Absent a change in Law, the
Company does not expect to have an obligation to withhold any Taxes on any required payment of the termination fee. 
 Section 15.
INDEMNIFICATION OBLIGATIONS. 
 (a) Company Indemnity. The Company and the Issuer (the
“Indemnifying Parties”) shall indemnify and hold harmless each Backstop Party and its Affiliates, equity holders, members, partners, general partners, managers and its and their respective representatives and controlling persons
(each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and costs and expenses (other than Taxes of the Backstop Parties except to the extent otherwise provided for in this Agreement)
(collectively, “Losses”) that any such Indemnified Person may incur or to which any such Indemnified Person may become subject arising out of or in connection with this Agreement, the Plan and the transactions contemplated hereby
and thereby, including the Commitments, the Rights Offering, the payment of the Backstop Commitment Premium or the use of the proceeds of the Rights Offering, the Transaction Expenses or any claim, challenge, litigation, investigation or proceeding
relating to any of the foregoing, regardless of whether any Indemnified Person is a party thereto, whether or not such proceedings are brought by the Company, the Issuer, their equity holders, Affiliates, creditors or any other Person, and reimburse
each Indemnified Person upon demand for reasonable documented (with such documentation subject to redaction to preserve attorney-client and work product privileges)
out-of-pocket legal or other third party expenses incurred in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to
serve or serving as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing (including in connection with the enforcement of the indemnification obligations set forth herein), irrespective of
whether or not the transactions contemplated by this Agreement or the Plan are consummated or whether or not this Agreement is terminated; provided that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses
(i) as to any Defaulting Commitment Party or any Indemnified Person related thereto, caused by such default by such Commitment Party or (ii) to the extent they are found by a final, non-appealable
judgment of a court of competent jurisdiction to arise from the bad faith, willful misconduct or gross negligence of such Indemnified Person or any of its Affiliates, equity holders, members, partners, general partners, managers, or their respective
representatives and controlling persons. 
 (b) Indemnification Procedure. Promptly after receipt by an Indemnified Person of notice
of the commencement of any claim, challenge, litigation, investigation or proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnified Person in respect thereof,
notify the Indemnifying Party in writing of the commencement thereof; provided that (A) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from 

  
 36 

 
any liability that it may have hereunder except to the extent it has been materially prejudiced by such failure and (B) the omission to so notify the Indemnifying Party will not relieve the
Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this Section 15. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Indemnifying
Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein, and, at its election by providing written notice to such Indemnified Person, the Indemnifying Party will be entitled to assume the defense thereof,
with counsel reasonably acceptable to such Indemnified Person; provided, (X) that the Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Indemnified Claim and shall pay the fees and expenses of
counsel retained by the Indemnified Person to the extent provided in Section 15(a) if the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Indemnified Claim, and such failure is not reasonably cured within ten
(10) Business Days of receipt of written notice from the applicable Indemnified Person, and (Y) if the parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party
and based on advice of such Indemnified Person’s counsel, there are legal defenses available to such Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the
right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Indemnified Claims (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one
separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local counsel is required)). Upon receipt of notice from the Indemnifying Party to such
Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel reasonably acceptable to the Indemnified Person, the Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such
Indemnified Person in connection with the defense thereof or participation therein (other than reasonable and documented out-of-pocket costs of investigation) unless
(i) such Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood,
however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in
which local counsel is required)), (ii) the Indemnifying Party shall not have employed counsel reasonably acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after the Indemnifying Party has received
notice of commencement of the Indemnified Claims from, or delivered on behalf of, the Indemnified Person, (iii) after the Indemnifying Party assumes the defense of the Indemnified Claims, the Indemnified Person determines in good faith that the
Indemnifying Party has failed or is failing to defend such claim and provides written notice of such determination, and such failure is not reasonably cured within ten (10) Business Days of receipt of such notice, or (iv) the Indemnifying
Party shall have authorized in writing the employment of counsel for such Indemnified Person. 

  
 37 

 (c) Settlement of Indemnified Claims. The Indemnifying Party shall not be liable for
any settlement of any Indemnified Claims effected by such Indemnified Person without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). If any settlement of any Indemnified
Claims is consummated with the written consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and
against any and all Losses by reason of such settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, this Section 15.
The Indemnifying Party shall not, without the prior written consent of an Indemnified Person (which consent shall be granted or withheld, conditioned or delayed in the Indemnified Person’s sole discretion), effect any settlement of any pending
or threatened Indemnified Claims in respect of which indemnity or contribution has been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such Indemnified Person in form and substance
satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such Indemnified Claims and (ii) such settlement does not include any statement as to or any admission of fault, culpability or a failure to
act by or on behalf of any Indemnified Person. 
 (d) Contribution. If for any reason the foregoing indemnification is unavailable to
any Indemnified Person or insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 15(a), then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a
result of such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying
Party, on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons, on the
other hand, shall be deemed to be in the same proportion as (i) the total value received or proposed to be received by the Company pursuant to the issuance and sale of the Convertible Bonds in the Rights Offering contemplated by this Agreement
and the Plan bears to (ii) the Backstop Commitment Premium paid or proposed to be paid to the Backstop Parties. The Indemnifying Parties also agree that no Indemnified Person shall have any liability based on their comparative or contributory
negligence to the Indemnifying Parties, any Person asserting claims on behalf of or in right of any of the Indemnifying Parties, or any other Person in connection with an Indemnified Claim. 

(e) Treatment of Indemnification Payments. All amounts paid by an Indemnifying Party to an Indemnified Person under this Section 15
shall, to the extent permitted by applicable law, be treated for all Tax purposes as adjustments to the purchase price for the Convertible Bonds subscribed for or purchased by such Indemnified Person. The provisions of this Section 15 are an
integral part of the transactions contemplated by this Agreement, and without these provisions, the Backstop Parties would not have entered into this Agreement, and subject to entry of the BCA Approval Order, the obligations of the Company under
this Section 15 shall constitute allowed administrative expenses of the Debtors’ estate under Sections 503(b) and 507 of the Bankruptcy Code and shall be payable without further order of the Bankruptcy Court, and the Company may comply
with the requirements of this Section 15 without further order of the Bankruptcy Court.

(c) Any proposed modification, amendment, waiver or supplement that does not comply with this Section 23 shall be ineffective and void
ab initio. 
 (d) The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a
further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise, and no delay in exercising, any right, power, or remedy under this Agreement shall operate as a waiver of,
any such right, power, or remedy or any provision of this Agreement, nor shall any single or partial exercise of such right, power, or remedy by such Party preclude any other or further exercise of such right, power, or remedy or the exercise of any
other right, power, or remedy. All remedies under this Agreement are cumulative and are not exclusive of any other remedies provided by Law. 

Section 24. SPECIFIC PERFORMANCE. It is understood and agreed by the Parties that money damages would be an
insufficient remedy for any breach of this Agreement by any Party, and each non-breaching Party shall be entitled to specific performance and injunctive or other equitable relief (without the posting of any
bond and without proof of actual damages) as a remedy of any such breach, including an order of the Bankruptcy Court or other court of competent jurisdiction requiring any Party to comply promptly with any of its obligations hereunder. 

Section 25. RULES OF CONSTRUCTION. This Agreement is the product of negotiations among the
Company and the Commitment Parties, and in the enforcement or interpretation of this Agreement, is to be interpreted in a neutral manner, and any presumption with regard to interpretation for or against any Party by reason of that Party having
drafted or caused to be drafted this Agreement, or any portion of this Agreement, shall not be effective in regard to the interpretation of this Agreement. The Company and its subsidiaries and the Commitment Parties were each represented by counsel

 This term sheet (this “Term
Sheet”) describes the material corporate governance provisions to be in effect after the restructuring and recapitalization transactions (the “Restructuring Transactions”) regarding certain indebtedness of Pioneer Energy
Services Corp. (“Pioneer”) and the other Company Parties. This Term Sheet shall not constitute (nor shall it be construed as) an offer or a legally binding obligation to buy or sell, or a solicitation of an offer to buy or sell, any
of the securities referred to herein, it being understood that such an offer or solicitation, if any, only will be made in compliance with applicable provisions of securities and/or other applicable laws. 

Capitalized terms used in this Term Sheet but not defined herein shall have the meanings set forth in the Restructuring Support Agreement. 

 

			
	 Topic
	  	 Proposal

	Reorganized Issuer	  	Either (i) Pioneer, as reorganized pursuant to and under the Plan, or any successor or assign thereto, by merger, amalgamation, consolidation, or otherwise, on or after the Plan Effective Date or (ii) a newly formed
Delaware corporation (the “Company”).
		
	Classes of Voting Securities	  	 Two classes of stock.
  

Voting common stock into which the convertible notes convert on conversion, having one vote per share.

 
 A class of special voting stock stapled to the convertible bonds that will be issued in
the rights offers in such an amount that the number of shares of such special voting stock that each noteholder receives is equal to the number of shares of common stock that the bonds are convertible into (i.e. such number of shares of special
voting stock will always equal the number of shares of common stock into which the bonds will convert at a given time). The special voting stock shall vote on all matters with the common stock on a 1:1 basis, but shall have no separate economic
interest (i.e. no rights to dividends, no redemption or liquidation rights) and will only be transferrable with the convertible notes with which such shares are stapled. The special voting stock shall automatically be redeemed for no or nominal
consideration on the conversion, redemption or payment in full of the stapled convertible bonds (such common stock and special voting stock, collectively, “Voting Stock”, and the holders of Voting Stock, the
“Holders”).

			
	 Topic
	  	 Proposal

	Board of Directors	  	 Initial Board: Initial Board of Directors (the “Board”) to consist of: (i) the chief executive officer (the
“CEO”) (who shall not be the chairman of the Board), and (ii) four additional directors, or such other number to be determined by the Required Consenting Noteholders, to be selected by the Ad Hoc Group of Noteholders. Each
Board member other than the CEO shall satisfy the independence requirements of the Nasdaq and NYSE.
  

Vote Standard: Board members to be elected by a majority of the outstanding shares of the Voting Stock. Board members will serve for one-year periods. A Nominating and Governance committee of the Board shall nominate directors to the board. Any director (except the CEO) shall satisfy the independence requirements of the Nasdaq and NYSE.

 
 Vacancies: The Board can fill any vacancies on the Board, until such seat is
filled at the next election of directors.
  
 Board Observation Rights: Any
Holder (and its affiliates) that individually owns more than 5% of the outstanding shares of the Voting Stock shall have the right to designate one Board observer.

		
	Board Actions	  	 A majority of the total number of directors then in office shall constitute a quorum, and the affirmative vote of a majority of the directors
present at a meeting at which a quorum is present shall be the act of the Board.
  
 The
Board or any committee thereof may act by written consent executed by all of the directors then in office or all members of such committee, as applicable, in lieu of a meeting.

		
	Shareholder Approvals	  	 The approval by the holders of 60% of the outstanding Voting Stock is required for a Deemed Liquidation Event.

 
 “Deemed Liquidation Event” shall mean acquisitions of beneficial
ownership of more than 50% of the voting power of the outstanding Voting Stock, any sales or dispositions of all or substantially all of the assets of the Company on a consolidated basis, or any merger, consolidation, recapitalization or similar
transaction where the Voting Stock is converted into, or exchanged for, any other consideration.
  

A special meeting may be called by stockholders of the Company in the same manner and upon the same thresholds as set forth in the Company’s current
Certificate of Incorporation and Bylaws.

		
	Related Party Transactions	  	The Company shall not, and shall not permit any of its subsidiaries to, enter into, amend or renew an agreement, arrangement or transaction with (a) any affiliate of the Company (including any of the Company’s directors or
officers or any entity in which any of the Company’s directors or officers has a financial interest) or (b) any owner of 5% or more of the Voting Stock, or an affiliate of such owner (each, a “Related Party”) unless such
action is approved by (i) the Board by a majority/supermajority of the disinterested directors and (ii) the Holders of a majority/supermajority of the Voting Stock, other than any Voting Stock held by the Related Party, except for
(A) customary compensation or benefits arrangements with a director, officer or other employee of the Company or any of its subsidiaries in the ordinary course of business and (B) intercompany agreements in the ordinary course of
business.

  
 2 

			
	 Topic
	  	 Proposal

	Preemptive Rights	  	All Holders will have preemptive rights to maintain their respective percentage of fully diluted equity with respect to any issuance of equity securities by the Company, subject to customary exceptions (including a merger event);
provided that such preemptive rights shall terminate at such time as the Company is listed on Nasdaq or NYSE.
		
	Transfer Restrictions	  	 Common stock will be transferrable without Company consent, subject to compliance with applicable securities laws.

 
 No ROFRs, tag-alongs or other restrictions on
transferability of common stock.

		
	Indemnification and Limitation on Liability	  	The organizational documents of the Company shall contain indemnification provisions and limitation on liability provisions applicable to directors and officers of the Company to the fullest extent permitted under Delaware
law.
		
	Listing/DTC1	  	 Common stock to be DTC-eligible and traded in the over-the-counter market acceptable to the Required Consenting Noteholders upon emergence.
  

Registration rights agreement to provide that a majority of holders of shares of Voting Stock subject to the registration rights agreement can require the
Company to use reasonable best efforts to cause the common stock to be listed on Nasdaq or NYSE in accordance with the applicable Nasdaq or NYSE listing requirements as promptly as practicable following delivery of notice.

 
 Convertible notes/special voting stock to be DTC eligible, or, if not reasonably
practicable, held in book-entry form through a transfer agent acceptable to the Required Consenting Noteholders, and to be made DTC eligible as soon as reasonably practicable following emergence using reasonable best efforts by the
Company.

		
	Information Rights	  	At any time the Company is not required to file public reports with the SEC, the Company will continue to provide such public reports on EDGAR as a voluntary filer.
		
	Registration Rights	  	Customary registration rights for common stock and convertible notes.
		
	Exclusive Forum	  	Delaware will be the exclusive forum for shareholder litigation.

  
  

	1 	 The listing terms can be revised by the Required Consenting Noteholders in consultation with the Company.

 EXHIBIT F 

MIP Term Sheet 

 TERM SHEET 

PIONEER ENERGY SERVICES CORP. 

EMPLOYEE INCENTIVE PLAN 
 This term
sheet (this “MIP Term Sheet”) summarizes the principal terms of an Employee Incentive Plan (the “MIP”) referenced in the Restructuring Support Agreement, dated as of February 28, 2020, (the “RSA”)
including the term sheet attached thereto as Exhibit B (the “Restructuring Term Sheet”) to which this this MIP Term Sheet is attached. For purposes of this MIP Term Sheet, capitalized terms not defined in this MIP Term Sheet shall
have the meanings ascribed to them in the RSA (including the Restructuring Term Sheet). The MIP shall be entered into among Reorganized Pioneer (the “Company”) and its affiliates (the “Pioneer Companies”) and the
participants in the MIP, which definitive documents shall contain terms consistent with those described below, except as may be otherwise agreed in accordance with the RSA. This term sheet does not afford any legally binding right to compensation or
awards under the MIP and no person shall have a right to such compensation or awards in respect of the MIP until such person executes, and becomes bound by such MIP documentation. 

 

			
	Overview:	 	 •  Incentive Equity Pool. There will be reserved, exclusively for the
Company’s employees, a pool of equity equal to 10% of the shares of the Company’s common stock outstanding on the Plan Effective Date on a fully diluted and fully distributed basis (including, for the avoidance of doubt, after giving
effect to the conversion of the Convertible Bonds) (such reserve, the “MIP Pool”). The precise amount of equity and number of shares to be reserved will be determined in a manner consistent with the intended effect of this MIP Term
Sheet.

		
		 	 •  Emergence Grants.

		
		 	 •  Except as specifically set forth in the third succeeding bullet below, 50% of
the shares of the Company’s common stock subject to the MIP Pool (the “Emergence Grant Pool”) will be allocated on or as soon as practicable following (but in no event more than 15 days following) the Plan Effective Date in
accordance with an allocation schedule to be reasonably determined by the new Board of Directors of the Company (the “New Board”), after good faith consultation with the Company’s Chief Executive Officer (the “Emergence
Grants”) in accordance with this MIP Term Sheet.

		
		 	 •  Each Emergence Grant will be 100% in the form of restricted
shares.

		
		 	 •  The grant of an Emergence Grant to an employee will be subject to and
conditioned upon the employee agreeing to be bound by the restrictive covenants (the “Restrictive Covenants”) referenced in the Post-Filing Severance Plan Term Sheet attached hereto as Appendix A (the “New Severance
Plan Term Sheet”).

		
		 	 •  To the extent an employee who is designated to receive an Emergence Grant does
not agree to be bound by the Restrictive Covenants, the shares not allocated to such employee shall be transferred from the Emergence Grant Pool to the Other Award Pool.

		
		 	 •  Other Awards. The remaining balance of the MIP Pool not allocated as
part of the Emergence Grants (the “Other Award Pool”) may be granted to the Company’s employees after the Plan Effective Date as determined by the New Board in its sole discretion, in such form and on such terms and conditions
as determined by the New Board.

		
	Emergence Grant Vesting:	 	 •  Time Vesting. 60% of the shares of the Company’s common stock that
are subject to the Emergence Grant Pool will vest in equal installments on each of the first three anniversaries of the Plan Effective Date, subject to the participant’s continued employment through each applicable vesting date (the
“Service Condition”).

		
		 	 •  Performance Vesting. 40% of the shares of the Company’s common
stock that are subject to the Emergence Grant Pool will vest subject to the achievement of specified performance measures over a period not to exceed three years, subject to the participant’s continued employment through the applicable vesting
date (the “Performance Condition”). The performance targets applicable to the Performance Condition will be reasonably determined by the New Board in its sole discretion after good faith consultation with the Company’s Chief
Executive Officer.

			
		 	 •  The allocation of vesting requirements for each participant’s Emergence
Grant between the Service Condition and the Performance Condition will be reasonably determined by the New Board after good faith consultation with the Company’s Chief Executive Officer.

		
	Treatment of Emergence Grants upon Termination of Employment:	 	 •  Without Cause or for Good Reason. If a participant is terminated without
Cause or resigns for Good Reason (as such terms are defined in the New Severance Plan Term Sheet), 100% of the participant’s unvested Emergence Grants will immediately vest, including the Emergence Grants subject to the Performance Condition at
target.
  
 •  Death or
Disability. If a participant’s employment is terminated due to the participant’s death or disability, the participant will receive one additional year of vesting of the participant’s Emergence Grant; provided that the portion of
the Emergence Grant that is subject to the Performance Condition will be pro-rated and subject to actual performance of the Performance Condition through the end of the performance period.

 
 •  Voluntary Termination
without Good Reason. If a participant voluntarily terminates employment without Good Reason, the unvested portion of the participant’s Emergence Grant will be immediately forfeited.

 
 •  Termination for Cause.
If a participant’s employment is terminated by the Company for Cause, the unvested portion of the participant’s Emergence Grant will be immediately forfeited.

		
	Voting Rights:	 	 •  Subject to the Company’s governance documents, all outstanding unvested
restricted shares granted under the Emergence Grants shall be entitled to voting rights to the extent that the Convertible Bonds have voting rights on an as-converted basis.

		
	Anti-Dilution:	 	 •  The MIP Pool and outstanding awards under the MIP will be subject to dilution
for future equity issuances (other than with respect to issuances (x) from the unallocated portions of the MIP or (y) resulting from the conversion of the Convertible Bonds), on a ratable basis with the common equity of the
Company.

		
	Severance:	 	 •  As a condition to participating in the MIP, each recipient of an Emergence
Grant shall agree to be a participant in the Post-Filing Severance Plan described in the New Severance Plan Term Sheet and shall acknowledge and agree that the participant will have no further rights under the Amended and Restated Pioneer Drilling
Services, Ltd. Key Executive Severance Plan.

defined in the KESP) prior to the Plan Effective Date. 

  

	 	•	 	 Severance Triggers: 

 

	 	•	 	 A participant’s termination without Cause (as defined below) following the Plan Effective Date, or

(g) willful misconduct with respect to the participant’s duties; provided that the conduct described in clauses (d), (e) and (g) shall not constitute Cause unless the Company has provided the participant with written notice of such
conduct and, to the extent curable, the participant fails to cure such conduct within 10 days of receiving such notice. 

  

	 	•	 	 “Good Reason” shall mean a voluntary termination by the participant due to the occurrence
(without the participant’s consent) of any of the following: (a) material diminution of the participant’s title, authority or responsibilities as in effect on the Plan Effective Date that is not remedied by the Company within 5

requirements.

WHEREAS, in order to facilitate the Plan and the Rights Offering, pursuant to this Agreement, and subject to the terms, conditions and
limitations set forth herein, (A) the Management Commitment Parties, severally and not jointly, have agreed to purchase from the Issuer, on the Plan Effective Date, the Management Commitment Securities for a purchase price of $1,795,000 and
(B) each Backstop Party, severally and not jointly, has agreed to purchase from the Issuer, on the Plan Effective Date, (i) all Rights Offering Securities allocated to such Backstop Party based on its ownership of Eligible Claims (as

$144,000 principal amount of Convertible Bonds issued at par and 10,800 shares of Special Voting Stock, in the case of such payment on the Plan Effective Date, or (ii) in cash, in the case of an earlier termination of this Agreement under the
circumstances set forth in Section 14(e); and 
 WHEREAS, for purposes of this Agreement, “Required Commitment
Parties” shall mean those Commitment Parties whose allocated amount of the Backstop Cap and Management Commitments (as defined below) collectively is more than 66.67% of the sum of the aggregate Backstop Cap and aggregate Management
Commitments held by all of the Commitment Parties (excluding any Defaulting Commitment Parties (as defined below)). 
 NOW, THEREFORE, in
consideration of the foregoing, and the representations, warranties and covenants set forth herein, and other good and valuable consideration, the Company and the Commitment Parties agree as follows:

Rights Offering procedures to be consistent with the provisions of this Agreement or otherwise acceptable to the Required Commitment Parties and the Company (the “Rights Offering Procedures”) and as follows:

Rule 501(a) under the Securities Act (as defined below) or (ii) a “qualified institutional buyer” as defined in Rule 144A under the Securities Act and makes certain other customary representations and warranties (each such holder, an
“Eligible Noteholder”) during the Rights Exercise Period will receive the rights (the “Subscription Rights”) with respect to the Notes Claims held by such Eligible Holder as of such time (such claims being
“Eligible Claims”) to subscribe for its pro rata share (measured as the amount of Eligible Claims held by such Eligible Noteholder (for the avoidance of doubt, after taking into account transfers of such Eligible Claims after
the Subscription Commencement Date) as compared to the aggregate amount of Notes Claims held by all holders of Notes Claims) of the Eligible Noteholder Initial Principal Amount of Rights Offering Securities. Pursuant to the RSA and the Plan, each
holder of Existing Equity Interests (as defined in the Term Sheet) that is either (i) an “accredited investor” as defined in Rule 501(a) under the Securities Act or (ii) a “qualified institutional buyer” as defined in
Rule 144A under the Securities Act and makes certain other customary representations and warranties (each such holder, an “Eligible Equity Holder”, and together with an Eligible Noteholder, “Eligible Holders”)
during the Rights Exercise Period will receive Subscription Rights to subscribe for its pro rata share (measured as the number of shares represented by the Existing Equity Interests held by such Eligible Equity Holder (for the avoidance of
doubt, after taking into account transfers of such Existing Equity Interests after the Subscription Commencement Date) as compared to the aggregate number of shares represented by the Existing Equity Interests held by all holders of Existing Equity
Interests) of the Eligible Equity Holder Initial Principal Amount of Rights Offering Securities. 

  
 3 

 (b) Subject to the terms and conditions of this Agreement, the Company hereby undertakes to
cause the Issuer to offer Rights Offering Securities for subscription by Eligible Holders of Eligible Claims pursuant to the RSA and the Plan as set forth in this Agreement. 

(c) The Company will cause the Issuer to issue Subscription Rights to purchase the Rights Offering Securities. Each Eligible Noteholder holding
Eligible Claims during the Rights Exercise Period will receive a Subscription Right to subscribe for its pro rata share of the Eligible Noteholder Initial Principal Amount of Rights Offering Securities. Each Eligible Equity Holder holding
Existing Equity Interests during the Rights Exercise Period will receive a Subscription Right to subscribe for its pro rata share of the Eligible Equity Holder Initial Principal Amount of Rights Offering Securities. 

(d) (1) Following the Petition Date, the Company will provide, or cause to be provided, to each Eligible Holder of Eligible Claims or Existing
Equity Interests a subscription form (the “Rights Offering Subscription Form”), whereby each Eligible Holder of Eligible Claims or Existing Equity Interests may exercise its Subscription Rights in whole or in part, provided
that such Eligible Holder of Eligible Claims or Existing Equity Interests (i) timely and properly executes and delivers its Rights Offering Subscription Form (with accompanying IRS Form W-9 or appropriate
IRS Form W-8, as applicable), and for transferees only, a transfer notice included as an exhibit to the Rights Offering Subscription Form, to the subscription agent for the Rights Offering selected by the
Company (the “Subscription Agent”) in advance of the Subscription Instruction Deadline and (ii) delivers the securities underlying its Eligible Claims or Existing Equity Interests through The Depository Trust Company Automated
Tender Offer Program in advance of the Subscription Instruction Deadline and (A) if such Eligible Holder is not a Backstop Party, the aggregate purchase price of the Rights Offering Securities elected to be purchased by the Eligible Holder of
Eligible Claims shall be paid in accordance with the Rights Offering Procedures or (B) if such Eligible Holder is a Backstop Party, such Backstop Party pays the aggregate purchase price of its Rights Offering Securities in accordance with
Section 1(g). 
 (2) In advance of the Subscription Instruction Deadline, each Backstop Party shall timely and properly exercise its
rights to purchase its allocated portion of the Rights Offering Securities (subject to its Backstop Cap), pursuant to the procedures set forth in the preceding clause (1) and the Rights Offering Procedures, subject to payment in accordance with
Section 1(g). For the avoidance of doubt, each Backstop Party shall fully exercise all Subscription Rights allotted to it for the purchase of the Rights Offering Securities, subject to its Backstop Cap. 

  
 4 

 (3) For purposes of this Agreement, the “Subscription Instruction Deadline”
means 5:00 p.m. New York City time on such date that is specified in the Rights Offering Procedures or such other date as the Company, subject to the approval of the Required Commitment Parties, may specify in a notice provided to the Eligible

national banking institutions in New York City are open to the public for conducting business and are not required or authorized to close. 

(e) The Company will cause the Issuer to issue the Rights Offering Securities to the Eligible Holders of Eligible Claims or Existing Equity

who elects to acquire such Rights Offering Securities shall be rounded down to the nearest security. 
 (f) If the Subscription Agent for any
reason does not receive from an Eligible Holder of Eligible Claims or Existing Equity Interests each of (i) a timely and duly completed Rights Offering Subscription Form, (ii) timely tender of the securities underlying its Eligible Claims
or Existing Equity Interests and (iii) timely payment for the Rights Offering Securities being purchased by such Eligible Holder of Eligible Claims or Existing Equity Interests, the Rights Offering Procedures shall provide that, unless

(g) No later than five (5) Business Days following the Subscription Instruction Deadline, the Company hereby agrees and undertakes to

Amount”, and such number of Unsubscribed Securities, the “Backstop Securities”); (iv) wire instructions for a segregated bank account of the Subscription Agent to which such Backstop Party shall deliver an amount equal to

(e) Subject to the entry of the Confirmation Order, which order shall approve this Section 2(e), on the Plan Effective Date, the Company
or the Issuer, as applicable, will reimburse or pay, as the case may be, the reasonable and documented out-of-pocket expenses incurred by the Backstop Parties, whether

expenses of Davis Polk & Wardwell LLP (“Davis Polk”), Haynes and Boone LLP, Houlihan Lokey, Inc., as counsel, local counsel, and financial advisor, respectively, to the Backstop Parties, in connection with the transactions
and agreements contemplated hereby, in each case in accordance with the terms of their applicable engagement letters and/or fee letters with the Company. 

(f) On the Plan Effective Date, the Commitment Parties will purchase, and the Issuer will sell, only such amount of Rights Offering Securities

(g) Delivery of the Rights Offering Securities and Unsubscribed Securities will be made by the Issuer to the respective Backstop Parties on the

Issuer to the Commitment Parties at least twenty four (24) hours in advance. 
 (h) Delivery of the Management Commitment Securities
will be made by the Issuer to the respective Management Commitment Parties on the Plan Effective Date upon the release of the Management Funding Amount of each Management Commitment Party by the Subscription Agent, upon which time such funds shall
be delivered to the Issuer by wire transfer of immediately available funds to the account specified by the Issuer to the Commitment Parties at least twenty four (24) hours in advance 

  
 7 

 (i) Delivery of the Convertible Bonds and Special Voting Stock in satisfaction of
(i) the Backstop Commitment Premium will be made by the Issuer to the respective Backstop Parties; and (ii) the Management Commitment Premium will be made by the Issuer to the respective Management Commitment Parties, in each case on the
Plan Effective Date. 
 Section 3. TRANSFER OF COMMITMENT. Each Commitment Party’s
Commitment shall be non-transferable without the consent of the Company and the Required Commitment Parties. Notwithstanding the foregoing, a Backstop Party may assign its Commitment to (1) any other
Backstop Party or (ii) any fund, account or investment vehicle that is controlled, managed, advised or sub-advised by such Backstop Party, an Affiliate thereof or the same investment manager, advisor or
subadvisor as the Backstop Party or an Affiliate of such investment manager, advisor or subadvisor (each, a “Related Fund”, and together with (1), “Permitted Transferees”), in which case such Permitted Transferee
shall agree in writing to be bound by the obligations of such transferring Backstop Party under this Agreement and the RSA and shall, as a condition of such transfer, provide the Company and the
non-transferring Backstop Parties with evidence reasonably satisfactory to them that such transferee is reasonably capable of fulfilling such obligations. For purposes of this Agreement, (i)
“Affiliate” shall mean with respect to any specified Person, any other Person that, at the time of determination, directly or indirectly through one or more intermediaries, Controls (as defined below), is Controlled by or is under
common Control with such specified Person and (ii) “Control” shall mean, as to any Person, the power to direct or cause the direction of the management and policies of such Person, whether through the ownership of voting securities,
by contract or otherwise. The terms “Controlled by,” “Controlled” and “under common Control with” shall have correlative meanings. 

Section 4. COMMITMENT PARTY DEFAULT. Any Backstop Party or Management Commitment Party that
fails to timely fund its Commitment or, in the case of a Backstop Party, fully exercise all Subscription Rights held by it in the Rights Offering, (a “Defaulting Commitment Party”) will be liable for its breach and the Company and
the Commitment Parties may enforce all of their respective rights and remedies hereunder and under applicable law, including the right to seek money damages (including setoff of any Plan recovery) and/or specific performance upon the failure to
timely fund by the Defaulting Commitment Party. Each of the non-defaulting Backstop Parties shall have the right, but not the obligation, to assume its pro rata share of such Defaulting Commitment
Party’s Commitment based on the proportion of its Backstop Commitment to the aggregate amount of Backstop Commitments of all non-defaulting Backstop Parties assuming such Defaulting Commitment
Party’s Commitment. If a Defaulting Commitment Party does not cure its failure to fund its Commitment within two (2) days after receiving notice of such failure from the Company, such Commitment Party shall not be entitled to any portion
of the Backstop Commitment Premium or Management Commitment Premium, as applicable. 

  
 8

or the board of directors, board of managers, or similar governing body of any of them, in such person’s capacity as a director, officer, or member of the Company or any of its subsidiaries, to take any action or to refrain from taking any
action to the extent the Company, such subsidiary, or such board of directors, board of managers, or similar governing body believes in good faith, based on advice of counsel, that the taking or failing to take such action would be inconsistent with

Bankruptcy Court approving this Agreement (the “BCA Approval Order”) shall not have occurred prior to the date that is 45 days after the Petition Date or if such order shall be reversed, stayed, dismissed, vacated, reconsidered,
modified or amended without the acquiescence or written consent (not to be unreasonably withheld, conditioned or delayed) of the Required Commitment Parties; 

(xvii) the Petition Date shall not have occurred on or prior to March 3, 2020; or 

(xviii) the RSA has been terminated in accordance with its terms. 

(d) Effect of Termination. Subject to Section 17, upon the effective date of the termination of this Agreement as to a Party (the
“Termination Date”), this Agreement shall be of no further force and effect as to such Party and each Party subject to such termination shall be immediately released from its or their respective liabilities, obligations,
commitments, undertakings, and agreements under or related to this Agreement, shall have no further rights, benefits or privileges hereunder and shall have all the rights and remedies that it would have had, had it not entered into this Agreement,
and no such rights or remedies shall be deemed waived pursuant to a claim of laches or estoppel, and shall be entitled to take all actions, whether with respect to the Restructuring Transactions or otherwise, that it would have been entitled to take
had it not entered into this Agreement, including with respect to any and all Claims (as defined in the RSA) or Causes of Action (as defined in the RSA); provided, that in no event shall

  
 34 

 
any such termination relieve a Party from liability for its breach or non-performance of its obligations hereunder before the Termination Date. Nothing in
this Agreement shall be construed as prohibiting the Company, any of its subsidiaries or any of the Backstop Parties from contesting whether any such termination is in accordance with its terms or to seek enforcement of any rights under this
Agreement that arose or existed before a Termination Date. Except as expressly provided in this Agreement, nothing in this Agreement is intended to, or does, in any manner waive, limit, impair, or restrict (a) any right of the Company or the
ability of the Company to protect and reserve its rights (including rights under this Agreement), remedies, and interests, including its claims against any Backstop Party, and (b) any right of any Backstop Party, or the ability of any Backstop
Party, to protect and preserve its rights (including rights under this Agreement), remedies, and interests, including its claims against the Company or any other Backstop Party. Notwithstanding any provision to the contrary in this Section 14,
no Party may exercise any of its respective termination rights as set forth herein if such Party has failed to perform or comply in all material respects with the terms and conditions of this Agreement (unless such failure to perform or comply
arises as a result of another Party’s actions or inactions), with such failure to perform or comply causing, or resulting in, the occurrence of the applicable termination event giving rise to such termination right. Nothing in this
Section 14(d) shall restrict the right of the Company or any of its subsidiaries to terminate this Agreement in accordance with Section 14(b)(ii). 

(e) Termination Fee. To the extent this Agreement is validly terminated in accordance with this Section 14 (other than
Section 14(b)(i) or Section 14(c)(iv)), the Company shall, within three (3) Business Days of such termination, pay or cause to be paid to the Commitment Parties that are not Defaulting Commitment Parties a non-refundable cash payment in an aggregate amount equal to (x) $9,440,000 payable to the Backstop Parties that are not Defaulting Commitment Parties, allocated pro rata based on each such Backstop
Party’s Backstop Commitment Percentage (excluding the Backstop Commitment Percentage of any Defaulting Commitment Party), plus (y) $143,000 payable to the Management Commitment Parties that are not Defaulting Commitment Parties, allocated
pro rata based on each such Management Commitment Party’s percentage (its “Management Commitment Percentage”), as set forth on Schedule 1 opposite such Management Commitment Party’s name (excluding the
Management Commitment Percentage of any Defaulting Commitment Party); provided that in the event that (1) this Agreement is validly terminated in accordance with Section 14(c)(xviii) because the RSA was validly terminated in
accordance with Section 13.03(a) of the RSA or (2) this Agreement is validly terminated in accordance with Section 14(a)(ii) or Section 14(a)(iii) due to a failure of a condition to closing set forth in Section 11 of this
Agreement to be satisfied by the Outside Date and (w) such failure is a result of the breach of the RSA by a Consenting Noteholder(s) (as defined in the RSA), (x) the Company has given notice of such breach to such Consenting Noteholder(s), (y)
within ten (10) Business Days following the giving of such notice, either such Consenting Noteholder(s) have failed to cure such breach or this Agreement has been terminated in accordance with Section 14(a)(ii), and (z) such ten
(10) Business Day period has elapsed prior to such termination pursuant to Section 14(c)(xviii) or Section 14(a)(iii), then any such breaching Consenting Noteholder who is also a Commitment Party hereunder shall not be entitled to
their pro rata share of any payment to be paid to the Commitment 

  
 35 

 
Parties pursuant to this Section. To the extent that all amounts due pursuant to this Section 14(e) shall have been paid by the Company or the applicable Commitment Parties in
connection with a termination of this Agreement, the Commitment Parties shall not have any additional recourse against the Company for any obligations or liabilities relating to or arising from this Agreement. Absent a change in Law, the
Company does not expect to have an obligation to withhold any Taxes on any required payment of the termination fee. 
 Section 15.
INDEMNIFICATION OBLIGATIONS. 
 (a) Company Indemnity. The Company and the Issuer (the
“Indemnifying Parties”) shall indemnify and hold harmless each Backstop Party and its Affiliates, equity holders, members, partners, general partners, managers and its and their respective representatives and controlling persons
(each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and costs and expenses (other than Taxes of the Backstop Parties except to the extent otherwise provided for in this Agreement)
(collectively, “Losses”) that any such Indemnified Person may incur or to which any such Indemnified Person may become subject arising out of or in connection with this Agreement, the Plan and the transactions contemplated hereby
and thereby, including the Commitments, the Rights Offering, the payment of the Backstop Commitment Premium or the use of the proceeds of the Rights Offering, the Transaction Expenses or any claim, challenge, litigation, investigation or proceeding
relating to any of the foregoing, regardless of whether any Indemnified Person is a party thereto, whether or not such proceedings are brought by the Company, the Issuer, their equity holders, Affiliates, creditors or any other Person, and reimburse
each Indemnified Person upon demand for reasonable documented (with such documentation subject to redaction to preserve attorney-client and work product privileges)
out-of-pocket legal or other third party expenses incurred in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to
serve or serving as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing (including in connection with the enforcement of the indemnification obligations set forth herein), irrespective of
whether or not the transactions contemplated by this Agreement or the Plan are consummated or whether or not this Agreement is terminated; provided that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses
(i) as to any Defaulting Commitment Party or any Indemnified Person related thereto, caused by such default by such Commitment Party or (ii) to the extent they are found by a final, non-appealable
judgment of a court of competent jurisdiction to arise from the bad faith, willful misconduct or gross negligence of such Indemnified Person or any of its Affiliates, equity holders, members, partners, general partners, managers, or their respective
representatives and controlling persons. 
 (b) Indemnification Procedure. Promptly after receipt by an Indemnified Person of notice
of the commencement of any claim, challenge, litigation, investigation or proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnified Person in respect thereof,
notify the Indemnifying Party in writing of the commencement thereof; provided that (A) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from 

  
 36 

 
any liability that it may have hereunder except to the extent it has been materially prejudiced by such failure and (B) the omission to so notify the Indemnifying Party will not relieve the
Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this Section 15. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Indemnifying
Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein, and, at its election by providing written notice to such Indemnified Person, the Indemnifying Party will be entitled to assume the defense thereof,
with counsel reasonably acceptable to such Indemnified Person; provided, (X) that the Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Indemnified Claim and shall pay the fees and expenses of
counsel retained by the Indemnified Person to the extent provided in Section 15(a) if the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Indemnified Claim, and such failure is not reasonably cured within ten
(10) Business Days of receipt of written notice from the applicable Indemnified Person, and (Y) if the parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party
and based on advice of such Indemnified Person’s counsel, there are legal defenses available to such Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the
right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Indemnified Claims (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one
separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local counsel is required)). Upon receipt of notice from the Indemnifying Party to such
Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel reasonably acceptable to the Indemnified Person, the Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such
Indemnified Person in connection with the defense thereof or participation therein (other than reasonable and documented out-of-pocket costs of investigation) unless
(i) such Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood,
however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in
which local counsel is required)), (ii) the Indemnifying Party shall not have employed counsel reasonably acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after the Indemnifying Party has received
notice of commencement of the Indemnified Claims from, or delivered on behalf of, the Indemnified Person, (iii) after the Indemnifying Party assumes the defense of the Indemnified Claims, the Indemnified Person determines in good faith that the
Indemnifying Party has failed or is failing to defend such claim and provides written notice of such determination, and such failure is not reasonably cured within ten (10) Business Days of receipt of such notice, or (iv) the Indemnifying
Party shall have authorized in writing the employment of counsel for such Indemnified Person. 

  
 37 

 (c) Settlement of Indemnified Claims. The Indemnifying Party shall not be liable for
any settlement of any Indemnified Claims effected by such Indemnified Person without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). If any settlement of any Indemnified
Claims is consummated with the written consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and
against any and all Losses by reason of such settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, this Section 15.
The Indemnifying Party shall not, without the prior written consent of an Indemnified Person (which consent shall be granted or withheld, conditioned or delayed in the Indemnified Person’s sole discretion), effect any settlement of any pending
or threatened Indemnified Claims in respect of which indemnity or contribution has been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such Indemnified Person in form and substance
satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such Indemnified Claims and (ii) such settlement does not include any statement as to or any admission of fault, culpability or a failure to
act by or on behalf of any Indemnified Person. 
 (d) Contribution. If for any reason the foregoing indemnification is unavailable to
any Indemnified Person or insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 15(a), then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a
result of such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying
Party, on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons, on the
other hand, shall be deemed to be in the same proportion as (i) the total value received or proposed to be received by the Company pursuant to the issuance and sale of the Convertible Bonds in the Rights Offering contemplated by this Agreement
and the Plan bears to (ii) the Backstop Commitment Premium paid or proposed to be paid to the Backstop Parties. The Indemnifying Parties also agree that no Indemnified Person shall have any liability based on their comparative or contributory
negligence to the Indemnifying Parties, any Person asserting claims on behalf of or in right of any of the Indemnifying Parties, or any other Person in connection with an Indemnified Claim. 

(e) Treatment of Indemnification Payments. All amounts paid by an Indemnifying Party to an Indemnified Person under this Section 15
shall, to the extent permitted by applicable law, be treated for all Tax purposes as adjustments to the purchase price for the Convertible Bonds subscribed for or purchased by such Indemnified Person. The provisions of this Section 15 are an
integral part of the transactions contemplated by this Agreement, and without these provisions, the Backstop Parties would not have entered into this Agreement, and subject to entry of the BCA Approval Order, the obligations of the Company under
this Section 15 shall constitute allowed administrative expenses of the Debtors’ estate under Sections 503(b) and 507 of the Bankruptcy Code and shall be payable without further order of the Bankruptcy Court, and the Company may comply
with the requirements of this Section 15 without further order of the Bankruptcy Court.

hereto in Section 14(d) and Sections 15 through 23 shall survive such termination and shall continue in full force and effect for the benefit of the parties hereto in accordance with the terms hereof. 

Section 18. ASSIGNMENT; THIRD PARTY BENEFICIARIES. This Agreement is intended
to bind and inure to the benefit of the Parties and their respective successors and permitted assigns, as applicable. There are no third-party beneficiaries under this Agreement, and, except as set forth in Section 3, the rights or obligations
of any Party under this Agreement may not be assigned, delegated, or transferred to any other Person or entity. 
 Section 19.
COMPLETE AGREEMENT. Except as otherwise explicitly provided in this Agreement, this Agreement constitutes the entire agreement among the Parties with respect to the subject matter of this Agreement and supersedes all
prior agreements, oral or written, among the Parties with respect thereto, other than any Confidentiality Agreement (as defined in the RSA). The Parties acknowledge and agree that they are not relying on any representations or warranties other than
as set forth in this Agreement. 
 Section 20. GOVERNING LAW; SUBMISSION TO
JURISDICTION; SELECTION OF FORUM; WAIVER OF TRIAL BY JURY. THIS AGREEMENT IS TO BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THE CHOSEN STATE, WITHOUT GIVING EFFECT TO ITS CONFLICT OF LAWS PRINCIPLES. Each Party to this Agreement agrees that it shall bring any action
or proceeding in respect of any claim arising out of or related to this Agreement, to the extent possible, in the Bankruptcy Court, and solely in connection with claims arising under this Agreement: (a) irrevocably submits to the exclusive
jurisdiction of the Bankruptcy Court; (b) waives any objection to laying venue in any such action or proceeding in the Bankruptcy Court; and (c) waives any objection that the Bankruptcy Court is an inconvenient forum or does not have
jurisdiction over any Party to this Agreement. EACH PARTY TO THIS AGREEMENT IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT. 
 Section 21. COUNTERPARTS. This Agreement may be executed and delivered in any number of counterparts and
by way of electronic signature and delivery, each such counterpart, when executed and delivered, shall be deemed an original, and all of which together shall constitute the same agreement. Except as expressly provided in this Agreement, each
individual executing this Agreement on behalf of a Party has been duly authorized and empowered to execute and deliver this Agreement on behalf of said Party. 

  
 40 

 Section 22. ACTION BY, OR
CONSENT OR APPROVAL OF, THE COMMITMENT PARTIES. Whenever this Agreement refers to any action to be taken by, or any consent or approval to be
given by, the Commitment Parties, unless otherwise expressly provided in any particular instance, such reference shall be deemed to require the action, consent or approval of the Required Commitment Parties. 

Section 23. AMENDMENTS AND WAIVERS. 

(a) This Agreement may not be modified, amended or supplemented, and no condition or requirement of this Agreement may be waived, in any manner
except in accordance with this Section 23. 
 (b) This Agreement may be modified, amended or supplemented in a writing signed by the
Company and the Required Commitment Parties; provided that amendments to this Section 23 shall require the consent of each Backstop Party. Notwithstanding the foregoing, if the proposed modification, amendment, waiver, or supplement has
a (1) disproportionate and adverse effect on any of the rights or obligations under this Agreement of any Backstop Party or (2) disproportionate and material adverse effect on any of the rights or obligations under this Agreement of any
Management Commitment Party, then the consent of each such affected Commitment Party shall also be required to effectuate such modification, amendment, waiver or supplement. 

(c) Any proposed modification, amendment, waiver or supplement that does not comply with this Section 23 shall be ineffective and void
ab initio. 
 (d) The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a
further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise, and no delay in exercising, any right, power, or remedy under this Agreement shall operate as a waiver of,
any such right, power, or remedy or any provision of this Agreement, nor shall any single or partial exercise of such right, power, or remedy by such Party preclude any other or further exercise of such right, power, or remedy or the exercise of any
other right, power, or remedy. All remedies under this Agreement are cumulative and are not exclusive of any other remedies provided by Law. 

Section 24. SPECIFIC PERFORMANCE. It is understood and agreed by the Parties that money damages would be an
insufficient remedy for any breach of this Agreement by any Party, and each non-breaching Party shall be entitled to specific performance and injunctive or other equitable relief (without the posting of any
bond and without proof of actual damages) as a remedy of any such breach, including an order of the Bankruptcy Court or other court of competent jurisdiction requiring any Party to comply promptly with any of its obligations hereunder. 

Section 25. RULES OF CONSTRUCTION. This Agreement is the product of negotiations among the
Company and the Commitment Parties, and in the enforcement or interpretation of this Agreement, is to be interpreted in a neutral manner, and any presumption with regard to interpretation for or against any Party by reason of that Party having
drafted or caused to be drafted this Agreement, or any portion of this Agreement, shall not be effective in regard to the interpretation of this Agreement. The Company and its subsidiaries and the Commitment Parties were each represented by counsel
during the negotiations and drafting of this Agreement and continue to be represented by counsel.
