(ii) as otherwise necessary to comply with applicable law. Except as set forth in the immediately preceding sentence, the Company shall not postpone or adjourn the Stockholders Meeting without the consent of the Noteholders. 

(ii) At all times from and after the date hereof to and through the completion of the Stockholders Meeting, the Noteholders shall, and shall
cause each of their respective Affiliates and each person named in Section 5.e. below (and any other director nominee proposed pursuant thereto) director nominees pursuant to the Stockholders Agreement to, use commercially reasonable
efforts to provide to the Company (and to update) such information relating to any of them for inclusion in the Proxy Statement as may be reasonably requested by the Company that is required by Schedule 14A under the Exchange Act or is
otherwise necessary, proper or advisable in connection with the preparation, filing and mailing thereof, including information in respect of its nominees to the board of directors of the Company pursuant to the terms and conditions of the
Stockholders Agreement (and customary questionnaires for purposes of preparing the Proxy Statement executed by such nominees) or any national securities exchange on which the Company’s shares are then listed. 

d. Listing. Subject to receipt of the Nasdaq Approval, the Company shall use its reasonable best efforts to take, or cause to be taken,
all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable laws and the rules and policies of the Nasdaq Global Select Market (“Nasdaq”) to cause the Shares to be
approved for listing on Nasdaq, subject to official notice of issuance (the “Listing”). 
 e. Board Composition. The
Company shall take such action as is necessary to cause (i) at the time of the Closing the full board of directors of the Company to consist of five directors and (ii) effective upon the Closing (1) the full board of directors to be
increased by three members to consist of eight directors and (2) Morgan D. Neff (or such other person as the Noteholders may designate in writing delivered to the Company not later than 5 business days prior to the Closing, provided that such
person is reasonably acceptable to the board of directors of the Company) to be appointed as a director in Class I (as such term is used in the Charter), Matthew D. Wilks (or such other person as the Noteholders may designate in writing
delivered to the Company not later than 5 business days prior to the Closing, provided that such person is reasonably acceptable to the board of directors of the Company) to be appointed as a director in Class II (as such term is used in the
Charter), and Matthew R. Kahn (or such other person as the Noteholders may designate in writing delivered to the Company not later than 5 business days prior to the Closing, provided that such person is reasonably acceptable to the board of
directors of the Company) to be appointed as a director in Class III (as such term is used in the Charter); provided, however, that the person designated by the Noteholders pursuant to the foregoing as a director in Class III
shall be required to execute and deliver to the Company, at the time of and as a condition to such appointment, a conditional resignation in such form as attached as Exhibit A to the Stockholders Agreement, which conditional resignation shall become
effective only in the circumstances in which the Noteholders are entitled to designate two (2) members of the board 

  
 12 








 
pursuant to Section 2.1.1(a) and 2.1.7(c) of the Stockholders Agreement. Should any Noteholder designee to the board of directors pursuant to this Section 5.e
(each, a “Noteholder Board Designee”) be rendered unable to, or refuse to, be appointed to, or for any other reason fail to serve or is not serving, on the board of directors of the Company and a replacement individual (the
“Noteholder Designee Replacement”) has not been designated in accordance with the preceding sentence then the Company shall not be obligated to designate an individual to fill such vacancy as of Closing and such vacancy shall be
filled as soon as practicable after the Closing in accordance with the Stockholders Agreement. Each person designated by the Noteholders and elected to the board of directors of the Company pursuant to this Section 5.e shall be referred
to as an “Elected Board Designee.” The Noteholders shall cause each Elected Board Designee to recuse themselves from any vote of approval of the board of directors regarding the Exchange Offer, including the determination of the
exchange ratio to be utilized therein (as contemplated by Section 5.g). 
 f. Payment of Expenses. The Company shall pay
or cause to be paid the Company’s fees, disbursements and expenses incurred in connection with the issuance of the Shares, and the Noteholders shall pay or caused to be paid the Noteholders’ fees, disbursements and expenses incurred in
connection with the Exchange Transaction, including the fees, disbursements and expenses of their respective advisors, counsel, accountants and other experts. For the avoidance of doubt, the Company acknowledges and agrees that it will pay or cause
to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with preparation and negotiation of this Agreement, the Additional Agreements, the Consent, the Supplemental
Indenture and the other agreements and instruments entered into in connection herewith, and the issue of the Shares; (ii) all fees and expenses associated with the preparation, filing and distribution of the Proxy Statement for, and the holding
of, the Stockholders Meeting, (iii) all fees and expenses associated with the Listing; (iv) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the
Consent and the Supplemental Indenture; and (v) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 5.f. The Noteholders acknowledge
and agrees, however, that, notwithstanding the foregoing, the Noteholders will pay or cause to be paid all of its own fees, disbursements and expenses incurred in connection with this Agreement, the Additional Agreements, the Consent, and the other
agreements and instruments to be entered into in connection herewith, including all fees, disbursements and expenses of counsel for and other advisers to the Noteholders in any connection herewith; provided, however that if this
Agreement is terminated for any reason other than the failure of the conditions to Closing set forth in Section 6.c., the Company shall pay or cause to be paid the reasonable and documented fees, disbursements and expenses of one firm of
legal counsel for the Noteholders incurred in connection with the Exchange Transaction up to $500,000. 
 g. Follow-on Exchange. If
the Charter Amendment Approval is obtained, then as soon as reasonably practicable, and in any event within 30 days, after the Closing, the Company will use its commercially reasonable efforts to make an offer (the “Exchange Offer”)
to the holders of the Notes, on terms, and subject to conditions, customary or appropriate in the good faith judgment of the board of directors of the Company to exchange any and all Notes for shares of Common Stock at an exchange ratio of shares of
Common Stock to each $1,000 aggregate principal amount of Notes equal to (i) the Exchange Ratio or (ii) if the Exchange Offer Adjusted Exchange Ratio is less than the Exchange Ratio, an exchange ratio not (A) greater than the Exchange
Ratio or (B) less than the Exchange Offer Adjusted Exchange Ratio.

the occurrence and existence of a Default or Event of Default with respect to such Default or Event of Default) or waived (with the effect of any such waiver being that the agent and lenders under the Credit Facility, after giving effect to any such

 7. Termination. 

a. This Agreement may be terminated: 

(i) by either the Company or the Noteholders, upon delivery of written notice of termination to the other Party, if the Closing has not
occurred on or before March 31, 2017, (the “End Date”); provided, however, that (x) the Company shall not be entitled to terminate this Agreement pursuant to this Section 7.a.(i) if (1) the
Company is in material breach of this Agreement as of the End Date or (2) any breach of this Agreement by the Company has caused the failure of any Closing condition or otherwise caused the Closing to not have occurred on or before the End Date
and (y) the Noteholders shall not be entitled to terminate this Agreement pursuant to this Section 7.a.(i) if (1) any Noteholder is in material breach of this Agreement as of the End Date or (2) any breach of this
Agreement by a Noteholder has caused the failure of any Closing condition or otherwise caused the Closing to not have occurred on or before the End Date. 

(ii) by the Company, upon delivery of written notice of termination to the Noteholders, if (A) any Noteholder has breached or failed to
perform any of its covenants or other agreements contained in this Agreement to be complied with by it such that the Closing condition set forth in Section 6.c.(iv) would not be satisfied or (B) there exists a breach of any
representation or warranty of any Noteholder contained in Section 3 of this Agreement such that the Closing condition set forth in Section 6.c.(i) would not be satisfied, and in the case of both clause (A) and clause
(B) above, such breach or failure to perform (x) has not been waived by the Company or cured on or before the earlier of thirty (30) days after receipt by the Noteholders of written notice thereof or the End Date or (y) is
incapable of being cured by the Noteholders by the End Date; provided, however, that the Company shall not be entitled to terminate this Agreement pursuant to this Section 7.a.(ii) if the Company is also in material breach
of this Agreement at such time; 

  
 16 








 (iii) by the Noteholders, upon written notice of termination to the Company, if (A) the

(iv) by the Noteholders, upon written notice of termination to the Company, if a material Default or an Event of Default exists under the
Credit Facility and, in either case, such Default or Event of Default has not been cured (with the effect of any such cure being that such Default or Event of Default no longer exists after giving effect to any such cure and, as a result, the

breach of this 

  
 17 








 
Agreement by the Company has caused the Nasdaq Approval to not be obtained and (y) the Noteholders shall not be entitled to terminate this Agreement pursuant to this
Section 7.a.(v) if (1) any Noteholder is in material breach of this Agreement as of the Termination Date or (2) any breach of this Agreement by a Noteholder has caused the Nasdaq Approval to not be obtained. 

b. Effect of Termination. In the event of termination of this Agreement by any Party as provided in Section 7.a., this
Agreement shall forthwith become void and there shall be no liability or obligation on the part of any Party (or any other person) with respect to this Agreement or the transactions contemplated in this Agreement or any Additional Agreement;
provided, however, that notwithstanding the foregoing, (a) no such termination shall relieve a Party from any breach by such Party prior to such termination and (b) the provisions of Section 3.k.,
Section 4.j., Section 5.f. (to the extent the Company is required thereby to pay any amounts to the Noteholders), this Section 7.b. and Section 9 (other than Section 9.j.,
Section 9.l. and Section 9.m.) shall survive such termination. 
 8. Indemnification. 

a. Indemnification Obligation. From and after the Closing, (i) the Company agrees to indemnify and hold harmless the Noteholders
and their Representatives from and against any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, attorneys’ fees, expenses and disbursements of any kind (“Losses”) which may be
imposed upon, incurred by or asserted against Noteholders or their Representatives in any manner relating to or arising out of any breach of any representation, warranty, covenant or agreement by the Company contained in this Agreement or the
certificate delivered by the Company pursuant to Section 6.b.(iii) and (ii) each Noteholder agrees to, severally, and not jointly nor jointly and severally, indemnify and hold harmless the Company and its Representatives, from and
against any Losses which may be imposed upon, incurred by or asserted against the Company or its Representatives in any manner relating to or arising out of any breach of any representation, warranty, covenant or agreement by such Noteholder
contained in this Agreement or the certificate delivered by such Noteholder pursuant to Section 6.c.(iii) (collectively, the “Indemnification Obligation”). 

b. Indemnification Procedure. All claims for indemnification by one or more Parties or Representatives entitled to be indemnified
hereunder (each, an “Indemnitee” and collectively, the “Indemnitee”) by one or more Parties hereto (each, an “Indemnitor” and collectively, the “Indemnitor”), shall be asserted and
resolved as follows: 
 (i) In the event that any action, suit, claim, proceeding, investigation, audit, examination, demand, assessment,
fine, judgment, settlement, compromise, interest, penalty, cost, remedial action and other expense (including, without limitation, reasonable attorneys’ fees and expenses) (collectively, “Actions”) for which the Indemnitee may
claim indemnity under this Agreement is asserted against or sought to be collected from the Indemnitee by a third party (a “Third-Party Claim”), the Indemnitee shall as promptly as practicable notify the Indemnitor following the
receipt by the Indemnitee of notice, written or otherwise, of such Action, specifying the nature of such Action and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of
such 

  
 18 








 
Action) (the “Claim Notice”); provided, however, that the failure so to notify the Indemnitor will not relieve the Indemnitor from any liability it may have to the
Indemnitee under this Agreement unless, and only to the extent that, such failure so to notify materially prejudices the Indemnitor or results in the loss of substantive rights or defenses. 

(ii) The Indemnitor shall have thirty calendar days from the date on which the Claim Notice is duly given (the “Notice
Period”) to notify the Indemnitee (A) whether or not it disputes the liability of the Indemnitor to the Indemnitee hereunder with respect to such claim or demand, and (B) whether or not the Indemnitor desires, at its sole cost and
expense, to defend the Indemnitee against such Action. If the Indemnitor notifies the Indemnitee within the Notice Period that it disputes its liability under the Indemnification Obligation to the Indemnitee with respect to a particular Action, and
such dispute is determined by a final and nonappealable order to be a wrongful denial of such liability, the Indemnitor shall be liable to the Indemnitee for the amount of any and all Losses arising from the Indemnitor’s failure to satisfy its
Indemnification Obligation with respect to such Action. 
 (iii) In the event the Indemnitor notifies (the “Indemnitor
Notice”) the Indemnitee within the Notice Period that it desires to defend the Indemnitee against such Action, then except as hereinafter provided the Indemnitor shall defend, at its sole cost and expense, the Indemnitee by appropriate
activities or proceedings, shall use its commercially reasonable efforts to settle or prosecute or otherwise contest, at Indemnitor’s election (subject to the terms of this Agreement), such activities or proceedings to a final conclusion in
such a manner as to attempt to avoid the Indemnitee becoming subject to any injunctive or other equitable order for relief or to liability for any other matter, and shall control the conduct of such defense; provided, however, that if
the Indemnitor fails to take reasonable steps necessary to defend the Indemnitee diligently against such Action after providing such Indemnitor Notice, within ten calendar days after receiving written notice from the Indemnitee stating that the
Indemnitee believes that the Indemnitor has failed to take such steps, the Indemnitee may assume its own defense and the Indemnitor shall be liable for all Losses arising out of such Action; provided, further, that the Indemnitor shall
not be entitled to assume the defense of any such Action pursuant to this Section 8 unless it has accepted and assumed in writing the obligation to indemnify the Indemnitee with respect to Losses arising from or relating to such Action,
and that the Indemnitor shall not in any Action in which Losses include any obligation other than, or in addition to, the payment of money for which the Indemnitor has assumed the obligation, without the prior written consent of the Indemnitee,
which consent shall not be unreasonably withheld or delayed, consent to the entry of any judgment against the Indemnitee or enter into any settlement or compromise which does not include, as an unconditional term thereof, the giving by all claimants
and plaintiffs to the Indemnitee of a release, in form and substance reasonably satisfactory to the Indemnitee, from all liability for which the Indemnitor is not liable pursuant to the terms of this Agreement in respect of any Action. If the
defendants in any such Action include both the indemnitor and the Indemnitee and the Indemnitee shall have reasonably concluded that there may be legal defenses or rights available to the Indemnitee which are different from, in actual or potential
conflict with, or additional to those available to the Indemnitor, the Indemnitee shall have the right to select one law firm to act at the Indemnitor’s expense as separate counsel, on behalf of the Indemnitee. In addition, if the Indemnitee
desires to participate in, but not control, any other defense or settlement, it may do so at its sole cost and expense. So long as the Indemnitor is defending in good faith any such 

  
 19 








 
Action, the Indemnitee shall not settle such Action without the consent of the Indemnitor, which shall not be unreasonably withheld or delayed; provided, however, that the
Indemnitee reserves the right to settle any Action at the Indemnitee’s sole cost and expense without the consent of the Indemnitor and the Indemnitor shall have no further liability or obligation with respect to any such Action so settled. 

(iv) Prior to the Indemnitor’s settling any Action, the defense of which it has assumed control, in which the settlement includes any
obligation of the Indemnitee other than, or in addition to, the payment of money for which the Indemnitor has assumed the obligation, the Indemnitor shall obtain the Indemnitee’s prior approval, confirmed in writing in accordance with the
notice provisions hereof, which approval shall not be unreasonably withheld or delayed. If such settlement consists of a bona fide offer and the Indemnitee notifies the Indemnitor of its disapproval of such settlement, the Indemnitee shall thereupon
become liable, from and after the date of its disapproval, for the amount of any award, settlement, costs, expenses (including, without limitation, reasonable attorneys’ fees and court costs) or other Losses in excess of the proposed settlement
amount and shall have the right to elect to control the defense of such Action at its sole cost and expense. 
 (v) In the event the
Indemnitee should have a claim for indemnification against the Indemnitor hereunder which does not involve a Third-Party Claim, the Indemnitee shall promptly send a Claim Notice with respect to such claim to the Indemnitor; provided,
however, that the failure so to notify the Indemnitor will not relieve the Indemnitor from any liability it may have to the Indemnitee under this Agreement unless, and only to the extent that, such failure so to notify materially prejudices
the Indemnitor or results in the loss of substantive rights or defenses. If the Indemnitor does not notify the Indemnitee within the Notice Period that it disputes such claim, the Indemnitor shall be liable for the amount of any Losses related
thereto. 
 c. Survival. All representations, warranties and agreements of the parties made in this Agreement shall survive for the
later of (i) six-months following the Closing or (ii) fifteen (15) business days after the date on which the Company files with the SEC its Annual Report on Form 10-K, including audited financial statements, for the year ending
December 31, 2016; provided, however, that the representations and warranties contained in Section 3.a. and Section 4.d. and the agreements set forth in Section 5.f., Section 5.g.
and Section 8 shall survive indefinitely (each such survival period as provided in this sentence, a “Survival Period”). The indemnifications set forth in Section 8.a. shall terminate in accordance with the
applicable Survival Period, except that any matters for which a specific written claim for indemnity has been delivered to the Indemnitor on or before the termination of the applicable Survival Period shall survive until the final resolution of such
claim.
 d. Remedies; Exclusive Remedy. Except (i) in the case of knowing and intentional actual fraud with respect to the
representations and warranties set forth in Section 3 and Section 4 of this Agreement or Willful and Material Breach of this Agreement by the Party against whom rights and remedies are sought to be enforced, and (ii) as
otherwise provided in Section 5.f., from and after Closing the rights and remedies under this Section 8 are the sole and exclusive rights and remedies and in lieu of any and all other rights and remedies that the Company and
its Representatives or the Noteholders and their Representatives may have against 

  
 20 








 
the Noteholders or the Company, respectively, under this Agreement or otherwise with respect to any breach of any representation or warranty or any failure to perform any covenant or agreement by
the Noteholders or the Company set forth in this Agreement. Effective as of the Closing, each of the Parties expressly waives, on their own behalf and on behalf of their Representatives any and all other rights, remedies and causes of action (other
than under this Section 8 and any exceptions thereto listed in the first sentence of this Section 8.d.) it or its Affiliates may have, in the case of the Company and its Representatives, against the Noteholders and, in the
case of the Noteholders and their Representatives, against the Company, now or in the future under any law with respect to the transactions contemplated by this Agreement (other than in respect of obligations undertaken pursuant to any of the
Additional Agreements). 
 9. Miscellaneous. 

a. Amendments and Waivers. Amendments or modifications to this Agreement may only be made, and compliance with any term, covenant,
agreement, condition or provision set forth herein may only be omitted or waived (either generally or in a particular instance and either retroactively or prospectively), upon the written consent of each party hereto. 

b. Notices. All notices, requests, consents, reports and demands shall be in writing, shall be deemed effectively given upon receipt and
shall be hand delivered, sent by facsimile or other electronic transmission (provided confirmation of receipt of the transmission is mechanically or electronically generated and kept on file by the sending party), or mailed, postage prepaid, to the
Noteholders at the applicable addresses and facsimile numbers or email addresses or to the Company at the address set forth below or, in each case, to such other address and/or facsimile number as may be furnished in writing to the other parties

(a) Until such time as the rights of the Holders are terminated or reduced in accordance with Section 2.1.7, the Holders,
collectively, shall be entitled to designate for nomination for election to the Board three (3) members of the Board as provided in Sections 2.1.2 and 2.1.3 hereof. If, at December 31, 2017 (the “Board Determination
Date’), the Holder Ownership Percentage is (x) less than 40%, the Holders shall cause the Board Designee who has been appointed as a Class III director to promptly tender his or her resignation, effective as of the Board Determination
Date, from the Board and any committee thereof on which he or she may be a member; or (y) equal to or greater than 40%, the Company shall cause a director other than a Board Designee to promptly tender his or her resignation, effective as of
the Board Determination Date, from the Board and any committee thereof on which he or she may be a member (either such resignation, the “Board Reduction Event”). In furtherance of the foregoing, Matthew R. Kahn (and each successor
Board Designee to Matthew R. Kahn’s position as a Class III director on the Board appointed or elected prior to the Board Determination Date) shall, prior to, and as a condition to his or her appointment to the Board as a Board Designee, and
the Holders shall cause Matthew R. Kahn (and each successor Board Designee to Matthew R. Kahn’s position as a Class III director on the Board appointed or elected prior to the Board Determination Date) to, execute an irrevocable conditional
resignation as director in the form attached hereto as Exhibit A. At the time of the Board Reduction Event, the Company shall take such action as is necessary to cause at such time the full board of directors of the Company to be decreased by
one member (with such decrease being the elimination of the directorship vacated by the Board Reduction Event to consist of seven (7) directors. 

(b) Members of the Board designated by the Holders pursuant to this Section 2.1.1 or appointed to fill a vacancy by the Holders as
provided in Section 2.1.2 or Section 2.1.5 shall be referred to as the “Board Designees.” The Company and the Board shall, subject to and consistent with the Board’s fiduciary duties and applicable law,
take such actions as necessary to cause Board Designees to be nominated and submitted to the stockholders of the Company for election to the Board, or appointed to the Board by the remaining members of the Board, as provided in
Section 2.1.2 and Section 2.1.4.

 (c) Prior to the Board Reduction Event, the number of directors on the Board shall not be
increased to greater than eight (8) without the unanimous approval of the Board Designees. Following the Board Reduction Event, the number of directors on the Board shall not be increased to greater than seven (7) without the unanimous
approval of the Board Designees. 
 2.1.2 Initial Board Representation. 

(a) Simultaneously with the execution and delivery of this Agreement, the three (3) Board Designees shall be appointed to the Board as
follows: (i) Morgan D. Neff shall be appointed as a Class I director on the Board; (ii) Matthew D. Wilks shall be appointed as a Class II director on the Board; and (iii) Matthew R. Kahn shall be appointed as a Class III director on
the Board. 
 2.1.3 Classified Board. For so long as the Company classifies and divides the Board into more than one class in which
the terms of the directors serving on the Board expire at different times depending on their class, then for so long as Holders are entitled to designate (A) two (2) Board Designees one such Board Designee shall serve as a Class I director
and one such Board Designee shall serve as a Class II director or (B) three (3) Board Designees one such Board Designee shall serve as a Class I director, one such Board Designee shall serve as a Class II director and one such Board
Designee shall serve as a Class III director. 
 2.1.4 Annual Meeting. 

(a) At each annual meeting of the Company’s stockholders or any special meeting in lieu thereof at which the term of any Board Designee
is to expire or at the date of which proxy materials for such meeting are mailed to the Company’s stockholders there shall be less than the maximum number of Board Designees that Holders are then entitled to designate serving on the Board, the
Holders, collectively, shall be entitled to designate for nomination as a director the number of individuals necessary so that, if such designees are elected to the Board at such annual meeting or any special meeting in lieu thereof, the maximum
number of Board Designees shall be serving on the Board. The Company and the Board shall, subject to and consistent with the Board’s fiduciary duties and applicable law, take such actions as necessary to cause each Board Designee so designated
by the Holders and to be nominated for election to the Board at each annual meeting of the Company’s stockholders or any special meeting in lieu thereof. To the extent the Company’s proxy statement for any annual meeting of stockholders,
or any special meeting in lieu thereof, includes a recommendation regarding the election of any other nominees to the Board, the Company and the Board shall, subject to and consistent with the Board’s fiduciary duties and applicable law,
include a recommendation of its Board that the stockholders also vote in favor of each Board Designee standing for election at such meeting. 

(b) For any annual meeting of the Company’s stockholders or any special meeting in lieu thereof at which Holders are entitled to
designate an individual for nomination as a director pursuant to Section 2.1.4(a), the Company shall use its good faith efforts to notify Holders in writing no less than ten (10) days before the advance notice deadline set forth in
the Company’s bylaws of such entitlement. If, at any time neither Holder advises the Board in writing, delivered to the Board not less than ninety (90) and no more than one hundred 

  
 8 








 
twenty (120) calendar days prior to the one year anniversary of the date of the Company’s proxy statement issued in connection with the prior year’s annual meeting in the case of
an annual meeting, and not less than sixty (60) days prior to the meeting in the case of a special meeting (provided, however, that if a Holder notifies the Board that Holders are unable to notify the Board within such time period, the Holders
and Board will work together in good faith to establish a later time period (taking into account the minimum amount of time the Company will reasonably need to include the information required by clauses (i) and (ii) below in any proxy
solicitation materials and prepare any other materials related thereto and to the election of directors)), of Holders intention to designate the number of directors which the Holders are then entitled to designate for nomination at the next annual
meeting of the Company’s stockholders or special meeting in lieu thereof, then the rights granted under this Section 2.1 with respect to the designation of Board Designees shall be applicable for such meeting only with respect to
the number of nominees as indicated in such writing, if any, that the Holders intend to designate, but shall continue to be fully effective with respect to subsequent meetings and interim vacancies. The Holders shall provide (i) the information
regarding each Board Designee as would be required to be included in solicitations of proxies for the election of directors in an election context or is otherwise required pursuant to the federal securities laws and regulations, had the nominee been
nominated, or intended to be nominated, by the Board and (ii) the consent of each such Board Designee to serve as a director of the Company if so elected. 

2.1.5 Board Committees. Subject to the Company’s corporate governance and independence guidelines, applicable law and the rules and
regulations of NASDAQ (or any other stock exchange on which the Company is then listed), including, if applicable, any enhanced requirements of with respect to certain committees of the Company, in each case, requiring that certain committee members
qualify as Independent, for so long as the Holders are represented on the Board by at least one Board Designee, the Company and the Board shall take such actions as necessary to cause at least one such Board Designee to be elected to, and to at all
times be a member of, each committee established by the Board based, if applicable, on whether or not such Board Designee qualifies as Independent; provided that such Board Designee, in his or her sole discretion, may decline to serve on such
committee. 
 2.1.6 Vacancies. If, prior to his or her election or appointment to the Board pursuant to this Section 2.1,
any Board Designee shall be unable or unwilling to serve as a director of the Company, then the Holders shall be entitled to nominate a replacement Board Designee, and the Company and the Board shall, subject to and consistent with the Board’s
fiduciary duties and applicable law, take such actions as necessary to cause such replacement Board Designee to be appointed to the Board or nominated and submitted to the stockholders, as applicable, pursuant to this Section 2.1. If,
following an election or appointment to the Board pursuant to this Section 2.1, any Board Designee shall resign or be removed or be unable to serve for any reason prior to the expiration of his or her term as a director of the Company,
then the Holders shall, within thirty (30) days of such event, notify the Board in writing of a replacement Board Designee, and the Company and the Board shall, subject to and consistent with the Board’s fiduciary duties and applicable
law, take such actions as necessary to cause such replacement Board Designee to be appointed to the Board to fill the unexpired term of the Board Designee who such new Board Designee is replacing.

 2.1.7 Reduction; Termination of Rights. The right of the Holders to designate directors
under this Section 2.1 shall be reduced and terminate as follows: 
 (a) Upon written request to the Holders, if the number of
Board Designees exceeds the number of directors the Holders shall be entitled to designate pursuant to Section 2.1.1 (as such number may be adjusted pursuant to this Section 2.1.7, the Holders shall cause the number of Board
Designee(s) in excess of the number of Board Designees to which the Holders are then entitled to designate to resign from the Board such that the number of Board Designees shall be reduced to the number the Holders are then entitled to designate.

 (b) Upon the completion of a Sale Transaction, the Holders’ right to designate Board Designees to the Board and its committees shall
immediately expire and the Holders shall cause each Board Designee then serving on the Board to resign from the Board immediately after the completion of a Sale Transaction; provided, however, that in the event such completed Sale
Transaction is a sale of all or substantially all of the consolidated assets of the Company and its Subsidiaries, the Holders’ right to designate Board Designees to the Board and its committees shall not expire until such time as a final
determination has been made with respect to the complete disposition of the proceeds from such Sale Transaction, at which point in time the Holders shall cause each Board Designee then serving on the Board to resign from the Board. 

(c) Upon the Holder Ownership Percentage being less than 40% at any time on or after the Board Determination Date, the Holders’ right to
designate members of the Board pursuant to Section 2.1.1(a) shall be reduced to the right to designate two (2) members of the Board; provided, that, subject to Section 2.1.1(a) with respect to a Board Reduction
Event, the then current term of the Board Designees then serving on the Board shall not be affected solely by the loss of such right. 
 (d)
Upon the Holder Ownership Percentage being reduced to less than 20%, the Holders’ right to designate members of the Board pursuant to Section 2.1.1(a) shall be reduced to the right to designate one (1) member of the Board;
provided, that the then current term of the Board Designees then serving on the Board shall not be affected solely by the loss of such right. 

(e) Upon the Holder Ownership Percentage being reduced to less than 10%, the Holders’ right to designate members to the Board pursuant to
Section 2.1.1(a) shall immediately expire; provided, that the then current term of the Board Designees then serving on the Board shall not be affected solely by the loss of such right. 

2.1.8 Company Policies; Fees; Costs and Expenses. The parties hereto acknowledge that each Board Designee, upon election to the Board,
will serve as a member of the Board and will be governed by the same protections and obligations regarding confidentiality, conflicts of interest, related party transactions, fiduciary duties, codes of conduct, trading and disclosure policies,
director resignation policies, and other governance guidelines and policies of the Company as other directors, and shall be required to preserve the confidentiality of Company business and information, including discussions or matters considered in
meetings of the Board or committees of the Board, and shall have the same rights 

  
 10 








 
and benefits, including with respect to insurance, indemnification and, with respect to Board Designees who qualify as Independent, compensation that are applicable to all Independent directors
of the Company. The Company will pay and reimburse each Board Designee (whether such Board Designee qualifies as Independent or not) for all reasonable out-of-pocket expenses incurred by such Board Designee in connection with his or her
participation in (or attendance at) meetings of the Board (and committees thereof) and the boards of directors (and committees thereof) of the Subsidiaries of the Company to the same extent as the Company reimburses all other directors of the
Company. 
 2.1.9 Voting. Until the occurrence of a Trigger Event, each Holder shall, and shall cause its Affiliates to, vote all
Voting Securities of the Company (including all Common Stock) held by such Holder and its Affiliates or over which such Holder or its Affiliates has voting control, and shall take all other necessary or desirable actions within its control
(including in its capacity as a stockholder, director, member of a board committee, officer or otherwise) to vote in the same proportion as shares of Voting Securities of the Company (including Common Stock) that are not held by such Holder or its
Affiliates or over which such Holder or its Affiliates does not have voting control with respect to (a) any ratification of the appointment of the Company’s independent registered public accounting firm; (b) the Board’s
recommendation with respect to the Company’s “say-on-pay” proposal or with respect to any other Company proposal or stockholder proposal (other than any proposal with respect to any Extraordinary Transaction); (c) each nominee
(including those that are not Board Designees) nominated and approved by the Director Nominating Committee; or (d) the removal of any Board Designees selected by the Director Nominating Committee to reduce the number of Board Designees to the
number of Board Designees to which the Holders are then entitled to designate if such Board Designees have not been removed in accordance with Section 2.1.7. Following the occurrence of a Trigger Event, the foregoing restrictions on each
of the Holders’ or its Affiliates’ voting of Voting Securities of the Company (including all Common Stock) held by such Holder or its Affiliates or over which such Holder or its Affiliates has voting control, shall terminate and each such
Holder or Affiliate shall be free to vote its Voting Securities in respect of each of the matters referenced in the immediately preceding sentence in any way it chooses to do so.

Section 3.1 Restrictions on Acquisitions. 

3.1.1 Subject to Section 3.1.2, from the date hereof until the eighteen (18) month anniversary of this Agreement, each Holder
agrees that other than in accordance herewith (including pursuant to the exercise of its rights under Section 2.1.1) or without the prior written consent of the Board, such Holder shall not, and shall cause each of its Affiliates not to,
directly or indirectly: 
 (a) in any manner acquire, agree to acquire or make any proposal or offer to acquire, directly or indirectly,
(i) any Voting Securities of the Company or any rights or options to acquire any such Voting Securities which would result in the Holder Ownership Percentage following such acquisition exceeding the Equity Cap or (ii) any property of the
Company or any rights or options to acquire any such property; 

  
 11

indirectly, any merger or business combination involving the Company or propose to have such Holder or an Affiliate of such Holder purchase, directly or indirectly, a material portion of the assets of the Company; 

(c) make, or in any way participate, directly or indirectly, in any “solicitation” of “proxies” (as such terms are used in
Regulation 14A promulgated under the Exchange Act) to vote or consent, or seek or advise or influence any person with respect to the voting of, or granting of a consent with respect to, any Voting Securities of the Company; 

(d) other than with other Holders, form, join or in any way participate in a “group” (within the meaning of Section 13(d)(3) of
the Exchange Act) with respect to any Voting Securities of the Company; 
 (e) except as may be required by law (provided that such legal
requirement does not arise as a result of or in connection with any breach of this Agreement by such Holder or its Representatives or Affiliates), disclose any intention, plan or arrangement inconsistent with the foregoing; 

(f) except as permitted pursuant to Section 3.2 hereof, provide, or act as agent for the purpose of obtaining, debt or equity financing
for any transaction described in clause (a) or (b) of this Section 3.1.1; or 
 (g) advise, assist or encourage any
other persons in connection with any of the foregoing. 
 Notwithstanding the foregoing provisions of this Section 3.1.1, the
restrictions set forth in this Section 3.1.1 shall terminate and be of no further force and effect if a public announcement or commencement is made of a tender or exchange offer by any Person (other than a Holder or its Affiliates) for,
or upon completion of which any Person would beneficially own (as such term is used in Rule 13d-3 of the Exchange Act), fifty percent (50%) or more of the outstanding Voting Securities of the Company, and the Board approves or fails to oppose
that tender or exchange offer in its statements in Schedule 14D-9 under the Exchange Act. 
 For the avoidance of doubt, nothing in
this Section 3.1.1 shall prohibit a Holder or any Affiliate of a Holder from engaging in discussions regarding potential transactions with unaffiliated third parties provided that it promptly and fully discloses any such discussions to
the Board and does not undertake any actions in furtherance of such a transaction without having first obtained the approval of the Board. 

3.1.2 Notwithstanding Section 3.1.1 or the expiration of the term thereof, each Holder shall not, and shall cause each of its
Affiliates not to, (a) until May 7, 2019, take any action (including any action described in Section 3.1.1) at any time if such action would result in a “Change of Control” (as such term is defined in the Revolving
Credit Facility) under the terms 

  
 12 








 
of the Revolving Credit Facility or (b) acquire, agree to acquire or make any proposal or offer to acquire, directly or indirectly, Common Stock such that, upon such acquisition, the Holder
Ownership Percentage would exceed the Equity Cap; provided that the restriction set forth in this Section 3.1.2(b) may be waived by the Company after a Trigger Event if such waiver is approved by a majority of the members of the
Board other than Board Designees and any other members of the Board nominated for election to the Board by Holders or any Holder. 

Section 3.2 Preemptive Rights. 

3.2.1 The Company shall not issue or sell, or agree to issue or sell, any Preemptive Debt Securities (other than (a) debt securities
issuable with respect to intercompany debt by and between the Company and any Subsidiaries or (b) in connection with the Exchange Offer (as such term is defined in the Exchange Agreement) contemplated by Section 5.g of the Exchange
Agreement) to any third party unless the Company shall have first delivered written notice (a “Preemptive Debt Notice”) to the Holders of the Company’s intent to issue, sell or exchange Preemptive Debt Securities, which
Preemptive Debt Notice shall (x) state the aggregate principal amount of the Preemptive Debt Securities the Company proposes to issue or sell and (y) may include the price and other material terms and conditions on which the Company
proposes to issue or sell the Preemptive Debt Securities (such items as described in this clause (y), the “Preemptive Debt Terms”). 

3.2.2 For a period of ten (10) Business Days from the date the Preemptive Debt Notice is delivered to Holders (the “Preemptive
Debt Offer Period”), the Holders may, by written notice to the Company (the “Preemptive Debt Election Notice”): (a) if the Preemptive Debt Notice included Preemptive Debt Terms, elect to purchase (“Preemptive
Debt Purchase Election”) all of the Preemptive Debt Securities, which shall constitute an offer to purchase such Preemptive Debt Securities which shall remain open and irrevocable for a period of ten (10) Business Days or
(b) offer to provide debt financing (“Alternative Debt Financing Offer”) in an amount equal to the aggregate principal amount of the Preemptive Debt Securities stated in the Preemptive Debt Notice and on such terms and
conditions as the Holders shall specify in the Election Notice, which shall constitute an offer to provide such debt financing which shall remain open and irrevocable until the end of the ADF Acceptance Period. 

3.2.3 If one or both Holders makes a timely Preemptive Debt Purchase Election, the Company shall provide written notice to such Holders
establishing the date of the new issuance of the Preemptive Debt Securities and the procedures for purchasing the Preemptive Debt Securities and the Holder(s) delivering such Preemptive Debt Purchase Election shall be obligated to provide the debt
financing referred to in the Preemptive Debt Notice on the Preemptive Debt Terms. 
 3.2.4 If the Company receives an Alternative Debt
Financing Offer from one or both Holders: 
 (a) The Company shall have thirty (30) days following its receipt of the Alternative Debt
Financing Offer (the “ADF Acceptance Period”) to determine whether to accept or reject the Alternative Debt Financing Offer. If the Company accepts the Alternative Debt Financing Offer, then the Holder(s) delivering such Alternative
Debt Financing Offer shall be obligated to provide the debt financing referred to in the Alternative Debt Financing Offer on the terms and conditions set forth in the Alternative Debt Financing Offer within sixty (60) days from the
Company’s acceptance. 

  
 13 








 (b) If the Company rejects or otherwise does not accept the Alternative Debt Financing Offer,
then the Company may proceed with the issuance of the Preemptive Debt Securities to a third party during the one hundred and fifty (150) day period following the expiration of the ADF Acceptance Period on such terms and conditions as determined
by the Company in its sole discretion; provided such terms and conditions of the Preemptive Debt Securities must be no less favorable, taken as a whole and considering all factors deemed relevant by the Company, than the Preemptive Debt Terms
or the terms and conditions of the Alternative Debt Financing Offer. If the Company has not issued or sold (or executed definitive documents to issue or sell) the Preemptive Debt Securities within the one hundred and fifty (150) days following
the expiration of the ADF Acceptance Period, any proposed issuance of such Preemptive Debt Securities shall once again be subject to the terms and conditions of this Section 3.2. Notwithstanding the foregoing, if the Preemptive Debt
Notice included Preemptive Debt Terms and the Company rejects or otherwise does not accept the Alternative Debt Financing Offer, Company shall so notify Holders, and Holders shall have three (3) Business Days following such notification to make
a Preemptive Debt Purchase Election pursuant to Section 3.2.2, and if Holders do not make a Preemptive Debt Purchase Election within such three (3) business day period the Company may proceed with the issuance of the Preemptive Debt
Securities to a third party in accordance with the preceding sentence. 
 3.2.5 If neither Holder delivers a Preemptive Debt Election Notice
during the Preemptive Debt Offer Period, the Company shall be entitled to sell such Preemptive Debt Securities specified in the Preemptive Debt Notice on such terms and conditions as determined by the Company in its sole discretion for a period of
one hundred and eighty (180) days following the expiration of the Preemptive Debt Offer Period. Any Preemptive Debt Securities to be sold by the Company following the expiration of such one hundred and eighty (180) day period must be
reoffered to the Holders pursuant to the terms of this Section 3.2. 
 3.2.6 The Company shall not issue or sell, or agree to
issue or sell, any Preemptive Equity Securities to any third party unless the Company shall have first delivered written notice (a “Preemptive Equity Notice”) to the Holders of the Company’s intent to issue, sell or exchange
Preemptive Equity Securities, which Preemptive Equity Notice (a) shall state the number and type of Preemptive Equity Securities proposed to be issued and (b) may include the price and other material terms and conditions on which the
Company proposes to issue the Preemptive Equity Securities (provided if the Company does not include the price at which the Company proposes to issue the Preemptive Equity Securities in a Preemptive Equity Notice, the Company shall use good faith
efforts to provide to the Holders reasonable advance notice of the price range or price, when determined, at which the Company proposes to issue the Preemptive Equity Securities). 

3.2.7 For a period of ten (10) Business Days from the date the Preemptive Equity Notice is delivered to Holders (the “Preemptive
Equity Offer Period”), the Holders may, by written notice to the Company (the “Preemptive Equity Election Notice”) elect to purchase (the “Preemptive Equity Purchase Election”), on the terms and conditions
specified in the 

  
 14 








 
Preemptive Equity Election Notice but subject to Section 3.1.2, up to a number of Preemptive Equity Securities, in the aggregate as to both Holders, equal to (a) the number of
Preemptive Equity Securities proposed to be issued or sold by the Company multiplied by (b) the Holder Ownership Percentage immediately prior to the delivery of the Preemptive Equity Notice by the Company, which shall constitute an offer
to purchase such Preemptive Equity Securities. 
 3.2.8 If one or both Holders makes a timely Preemptive Equity Purchase Election, the
Company shall provide written notice to such Holder(s) establishing the date of the new issuance of Preemptive Equity Securities and the procedures for purchasing the Preemptive Equity Securities. Notwithstanding the foregoing, the Company shall be
under no obligation to consummate any proposed issuance of Preemptive Equity Securities, nor shall there be any liability on the part of the Company, or to the Board, to the Holders if the Company has not consummated any proposed issuance of
Preemptive Equity Securities pursuant to this Section 3.2 for whatever reason, regardless of whether the Company shall have delivered a Preemptive Equity Notice. 

3.2.9 If neither Holder delivers a Preemptive Equity Election Notice during the Preemptive Equity Offer Period, the Company shall be entitled
to sell such Preemptive Equity Securities in the Preemptive Equity Notice on such terms and conditions as determined by the Company in its sole discretion for a period of one hundred and fifty (150) days following the expiration of the
Preemptive Equity Offer Period. Any Preemptive Equity Securities to be sold by the Company following expiration of such one hundred and fifty (150) day period must be reoffered to the Holders pursuant to the terms of this
Section 3.2. 
 Section 3.3 Restrictions on Transfers. 

3.3.1 From the date hereof until the six (6) month anniversary of the this Agreement (the “Restricted Period”), each
Holder agrees that, without the prior written consent of the Company, such Holder shall not, and it shall cause each of its Affiliates not to, directly or indirectly, Transfer any shares of Common Stock (or any rights or interests of any nature
whatsoever in or with respect to any shares of Common Stock) beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) by such Holder or its Affiliates. 

3.3.2 Upon the completion of the Restricted Period, the Holders agree not to Transfer more than five percent (5%) of the shares of Common
Stock beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) by the Holders and their Affiliates, in the aggregate, per each rolling ninety (90) day period beginning with a Holder’s (or its Affiliate’s) first
transfer of shares of Common Stock after the termination of the Restricted Period until the date that is eighteen (18) months from the end of the Restricted Period (the “Dribble Out Period”); provided, however,
that, following the date that is six (6) months after the completion of the Restricted Period, the foregoing restriction set forth in this Section 3.3.2 shall not apply to any underwritten offering effected pursuant to a
Holder’s rights under, and subject to the terms of, the Registration Rights Agreement. 
 3.3.3 Upon the completion of the Dribble Out
Period, each Holder will be free to Transfer shares of Common Stock without limitation, except that all such Transfers shall be in compliance with applicable state and federal securities laws and the terms of this Agreement. 

  
 15 








 3.3.4 Notwithstanding the foregoing, a Holder may Transfer shares of Common Stock (i) to
any Affiliate of such Holder; provided, that in the case of any such Transfer to such Affiliate, the Affiliate shall agree to be bound by the terms of this Section 3.3 and (ii) pursuant to any merger, consolidation,
recapitalization or reorganization of the Company with or into a third-party purchaser. 
 3.3.5 Notwithstanding this
Section 3.3, each Holder agrees that it shall not, and it shall cause each of its Affiliates not to, directly or indirectly, Transfer any shares of Common Stock (or any rights or interests of any nature whatsoever in or with respect to
any shares of Common Stock) beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) by the Holder or its Affiliates if such Transfer would result in a “Change of Control” (as such term is defined the Revolving Credit
Facility) under the terms of the Revolving Credit Facility; provided, however, that the foregoing restriction shall not apply to any Transfer effected (a) as a brokers’ transaction on a national securities exchange or
(b) pursuant to an underwritten public offering registered under the Securities Act.

 Section 5.4 Successors and Assigns. This Agreement shall be binding upon the Company, the Holders, and their
respective successors and permitted assigns (which shall be deemed to include any Affiliate of any Holder to which a Holder Transfers any shares of Common Stock); provided that if any Holder Transfers any shares of Common Stock to any of its
Affiliates such Holder shall remain the sole party entitled to exercise the rights of such Holder under this Agreement and such Affiliate shall (and such Holder shall require such Affiliate to execute a joinder to this Agreement in form and
substance reasonably acceptable to the Company agreeing to) be bound by the terms of this Agreement with respect to all shares of Common Stock held by such Affiliate. No Holder may assign any of its rights under this Agreement to any other Person
(including any transferee of any Common Stock held by a Holder) without the prior written consent of the Company, which consent may be granted or denied by the Company in its sole discretion and to be valid must be approved by a majority of the
members of the Board other than Board Designees and any other members of the Board nominated for election to the Board by Holders or any Holder, and any assignment in violation of the foregoing shall be void ab initio. 

Section 5.5 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be deemed to be an
original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. This Agreement and any signed agreement entered into in connection herewith or contemplated hereby, and any amendments
hereto or thereto, to the extent signed and delivered by facsimile, by electronic mail in “portable document format” (“.pdf”) form, or any other electronic transmission, shall be treated in all manner and respects as an original
contract and shall be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. 

Section 5.6 Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction
is, as to such jurisdiction, ineffective to the extent of any such prohibition, unenforceability or nonauthorization without invalidating the remaining provisions hereof, or affecting the validity, enforceability or legality of such provision in any
other jurisdiction, unless the ineffectiveness of such provision would result in such a material change as to cause completion of the transactions contemplated hereby to be unreasonable. Upon a determination that any provision of this Agreement is
prohibited, unenforceable or not authorized, the parties hereto agree to negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible, in a mutually acceptable manner, in order
that the transactions contemplated hereby are consummated as originally contemplated to the fullest extent possible. 
 Section 5.7
Specific Performance. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, including if the
parties hereto fail to take any action required of them hereunder to consummate this Agreement. It is accordingly agreed that, 

  
 18 








 
in addition to any other applicable remedies at law or equity, the parties shall be entitled to an injunction or injunctions, without proof of damages, to prevent breaches of this Agreement and
to enforce specifically the terms and provisions of this Agreement. Each party hereto agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that (i) the other party has an
adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or in equity. Each of the parties hereto hereby waives (i) any defenses in any action for specific performance, including
the defense that a remedy at law would be adequate and (ii) any requirement under any law to post a bond or other security as a prerequisite to obtaining equitable relief. 

Section 5.8 No Waivers; Amendments. 

5.8.1 No failure or delay on the part of the Company or the Holder in exercising any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not
exclusive of any remedies that may be available to the Company or any Holder at law or in equity or otherwise. 
 5.8.2 Any provision of this
Agreement may be amended or waived if, but only if, such amendment or waiver makes specific reference to this Agreement, and, (i) in the case of an amendment, such amendment is with the written consent of the Company and each Holder, and (ii),
in the case of a waiver, such waiver is signed by the Person against whom it is to be enforced; provided that any amendment of this Agreement or waiver by the Company hereunder shall only be effective if such amendment or waiver is approved by a
majority of the members of the Board other than Board Designees and any other members of the Board nominated for election to the Board by Holders or any Holder. 

Section 5.9 Non-Recourse. All claims, obligations, liabilities, or causes of action (whether in contract or in tort, in law or in
equity, or granted by statute) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, execution, or performance of this Agreement (including any
representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be made only against (and are expressly limited to) the entities that are expressly identified as parties in the preamble to this Agreement
(“Contracting Parties”). No Person who is not a Contracting Party, including any director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, or representative of, and any financial
advisor or lender to, any Contracting Party, or any director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, or representative of, and any financial advisor or lender to, any of the foregoing
(“Non-party Affiliates”), shall have any liability (whether in contract or in tort, in law or in equity, or granted by statute) for any claims, causes of action, obligations, or liabilities arising under, out of, in connection with,
or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach; and, to the maximum extent permitted by law, each Contracting Party hereby waives and
releases all such liabilities, claims, causes of action, and obligations against any such Non-party Affiliates. 

  
 19 








 Section 5.10 Further Assurances. Each party shall cooperate and shall take such
further action and shall execute and deliver such further documents as may be reasonably requested by any other party in order to carry out the provisions and purposes of this Agreement. 

Section 5.11 Entire Agreement. This Agreement (including all schedules and exhibits hereto) contains the entire agreement among
the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written, with respect to such matters. 

Section 5.12 Ownership and Aggregation of Common Stock; Action by Holders. 

5.12.1 All shares of Common Stock beneficially owned by each Holder and its Affiliates shall be aggregated for purposes of interpreting the
term and terms of, and determining the application and availability of any obligations and rights under, this Agreement, unless the context otherwise requires. 

5.12.2 Any action to be taken or consent or approval to be given by Holders pursuant to this Agreement shall be deemed taken, consented to or
approved upon the affirmative consent or approval by either Holder; provided that, if the Company receives conflicting direction, consents or approvals from the Holders with respect to any action to be taken or consent or approval to be given by
Holders pursuant to this Agreement, then any action to be taken or consent or approval to be given by Holders pursuant to this Agreement shall be deemed taken, consented to or approved upon the affirmative consent or approval by the Holder that
holds a majority of the Common Stock held by both Holders. 
 5.12.3 From time to time upon the written request by the Company, each Holder
shall provide to the Company in writing a statement setting forth the number of shares of Common stock beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) by such Holder, certified by an officer or other duly authorized
representative of such Holder.

 EXHIBIT B 

REGISTRATION RIGHTS AGREEMENT 

This REGISTRATION RIGHTS AGREEMENT, dated as of [●], 201[●] (this “Agreement”), is by and among Approach
Resources Inc., a Delaware corporation (the “Company”), and each of Wilks Brothers, LLC and SDW Investments, LLC (collectively, the “Holders”, and each, a “Holder”). 

RECITALS 
 WHEREAS,
on [●], 201[●], the Holders acquired the number of shares of common stock, par value $0.01 per share, of the Company (the “Company Common Stock”) set forth on Schedule A pursuant to the Exchange Agreement, dated
November 2, 2016, by and between the Company and the Holders (the “Exchange Agreement”); and 
 WHEREAS,
resales by a Holder of the Company Common Stock may be required to be registered under the Securities Act and applicable state securities laws, depending upon the status of such Holder or the intended method of distribution of the Company Common
Stock. 
 NOW, THEREFORE, in consideration of the premises, mutual covenants and agreements hereinafter contained and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 ARTICLE
I – REGISTRATION RIGHTS 
 1.1 Demand Registration. 

(a) From and after the one (1) year anniversary following the Closing, and subject to Section 1.1(b),
Section 1.1(c) and Section 2.3, upon written request from a Holder requesting that the Company effect the registration under the Securities Act of all or part of the Registrable Securities held by such Holder, which notice
may be delivered at any time after such one (1) year anniversary and which notice shall specify the intended method or methods of disposition of such Registrable Securities (“Registration Request Notice”), unless such
Registrable Securities are included in a currently effective Registration Statement permitting the resale of such Registrable Securities in the manner contemplated by the Registration Request Notice, the Company will use its commercially reasonable
efforts to file the appropriate Registration Statement under the Securities Act with the SEC as promptly as reasonably practicable after receipt of the Registration Request Notice and, as promptly as reasonably practicable following such
Registration Request Notice, cause such Registration Statement to be declared effective by the SEC and to permit the disposition of such Registrable Securities in accordance with the intended method or methods of disposition stated in such
Registration Request Notice. The Company shall not be required to maintain the effectiveness of such Registration Statement beyond the earlier to occur of (i) one hundred twenty 120 days after the effective date thereof and
(ii) consummation of the distribution by Holder of the Registrable Securities included in such Registration Statement (such period, the “Effectiveness Period”). 

(b) Notwithstanding Section 1.1(a), if the Company previously shall have caused a Registration Statement to be declared effective
by the SEC with respect to the Registrable Securities, the Company shall not be required to cause a subsequent Registration Statement to be declared effective by the SEC pursuant to this Section 1.1 until a period of one hundred twenty
(120) days shall have elapsed from the effective date of the most recent such previous registration. 
 (c) Notwithstanding
Section 1.1(a), the Company shall not be required to effect (i) more than two (2) registrations pursuant to this Section 1.1 in any twelve (12) consecutive month period or (ii) a registration of
Registrable Securities, the fair market value of which on the date of receipt by the Company of the Registration Request Notice is less than twenty million dollars ($20,000,000). 







 1.2 Piggyback Registration. 

(a) If at any time the Company proposes to register any of its equity securities (other than pursuant to an Excluded Registration) under the
Securities Act for sale to the public (whether for the account of the Company or the account of any securityholder of the Company) and the form of Registration Statement to be used permits the registration of Registrable Securities, the Company
shall give prompt written notice to each Holder (which notice shall be given not less than fifteen (15) days prior to the anticipated filing date), which notice shall offer each Holder the opportunity to include any or all of its Registrable
Securities in such Registration Statement, subject to the limitations contained in Section 1.2(b) hereof. If a Holder (in such capacity, a “Participating Holder”) desires to have its Registrable Securities included in
such Registration Statement, it shall so advise the Company in writing (stating the number of shares desired to be registered) within ten (10) days after the date of such notice from the Company. Each Holder shall have the right to withdraw
such Holder’s request for inclusion of Holder’s Registrable Securities in any registration statement pursuant to this Section 1.2(a) by giving written notice to the Company of such withdrawal. Subject to
Section 1.2(b) below, the Company shall use commercially reasonable efforts to include in such Registration Statement all such Registrable Securities so requested to be included therein; provided, however, that the Company
may at any time and in its sole and absolute discretion withdraw or cease proceeding with any such registration if it shall at the same time withdraw or cease proceeding with the registration of all other equity securities originally proposed to be
registered. The Company shall not be required to maintain the effectiveness of such Registration Statement beyond the Effectiveness Period. 

(b) If a nationally recognized independent investment banking firm selected by the Company to act as lead underwriter in connection with the
public offering of securities under this Section 1.2 advises the Company that the inclusion of the Registrable Securities requested to be included in the Registration Statement pursuant to Section 1.2(a) will materially and
adversely affect the price or success of such offering (a “Material Adverse Effect”), the Company will be obligated to include in the Registration Statement (after registering all such shares for its own account), as to each
Participating Holder, only a portion of the shares such Participating Holder has requested be registered equal to the product of: (i) the ratio which such Participating Holder’s requested shares bears to the total number of shares
requested to be included in such Registration Statement subject to Section 1.2(a) by all Persons (including the Participating Holder) who have requested (pursuant to contractual registration rights) that their shares be included in such
Registration Statement; and (ii) the maximum number of Registrable Securities that such lead underwriter advises may be sold in an offering covered by the Registration Statement without a Material Adverse Effect. If, as a result of the
provisions of this Section 1.2(b), the Participating Holder shall not be entitled to include all Registrable Securities in a registration that the Participating Holder has requested to be so included, the Participating Holder may
withdraw such its request to include Registrable Securities in such Registration Statement by giving written notice to the Company of such withdrawal. 

1.3 Expenses. The Company shall bear all Registration Expenses in connection with any Registration Statement pursuant to this
Article I, whether or not such Registration Statement becomes effective; provided, however, that if a Holder requests a registration pursuant to Section 1.1 and subsequently withdraws its request, then such Holder
shall either pay all Registration Expenses incurred in connection with such registration or such registration will count as a registration for purposes of Section 1.1(c) and such Holder shall not have the right to request another
registration pursuant to Section 1.1 during the subsequent ninety (90) days, unless the withdrawal of such request is the result of facts or circumstances relating to the Company or the Company Common Stock that arise after the date
on which such request was made and would have a material adverse effect on the offering of the Registrable Securities. 

  
 2 








 1.4 Company Purchase Option. Notwithstanding the terms of this Agreement, if at any
time a Holder requests any Registrable Securities be included in a registration statement pursuant to this Agreement and at such time securities of the same class or series as the Registrable Securities are traded on a national securities exchange
or trading system or any other recognized quotation system which regularly provides quotes on such securities (a “Trading Forum”), the Company shall have the right and option, in its sole discretion, to, in lieu of including such
Registrable Securities in such Registration Statement, purchase all or any portion of such Registrable Securities requested to be included in such Registration Statement at the closing or last sales price of such security reported by such Trading
Forum on the date of Holder’s request for inclusion of such Registrable Securities in such Registration Statement is received by the Company, or, if there is no such reported quote for such date on any Trading Forum, the last reported closing
or sales price, as applicable, of such security by a Trading Forum. 
 ARTICLE II – PROCEDURES 

2.1 Underwriting.  

(a) For so long as a Holder holds Registrable Securities, such Holder may request by giving written notice (an “Underwriting
Request”) to the Company that an offering permitted under Section 1.1(a) shall be in the form of an underwritten offering (each, an “Underwritten Offering”); provided, however, that in the case of
each such Underwritten Offering, such Holder will be entitled to make such demand only if the proceeds from the sale of Registrable Securities in the offering (before the deduction of underwriting discounts) is reasonably expected to exceed, in the
aggregate, twenty million dollars ($20,000,000); provided, further that the Company shall not be obligated to effect more than two (2) Underwritten Offerings during any twelve (12) consecutive month period and shall not be
obligated to effect an Underwritten Offering within one hundred twenty (120) days after the pricing of a previous Underwritten Offering. 

(b) All Underwriting Requests shall specify the approximate number of Registrable Securities to be sold in the Underwritten Offering and the
expected price range (net of underwriting discounts and commissions) of such Underwritten Offering. 
 (c) With respect to any such
Underwritten Offering, the Holder making the request shall select an investment banking firm of international standing to be the managing underwriter for the offering, which firm shall be reasonably acceptable to the Company. The Company will enter
into and perform its obligations under an underwriting agreement with the underwriters for such Underwritten Offering, such agreement to contain such representations and warranties by the Company and such other terms and provisions as are
customarily contained in underwriting agreements with respect to secondary distributions, which may include, without limitation, indemnities and contribution to the effect and to the extent provided in Article III and the provision of
opinions of counsel and accountants’ letters as are customarily delivered by issuers to underwriters in secondary underwritten public offerings of securities. The Holders shall be a party to any such underwriting agreement and the
representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Holders of such securities, but only to the extent such
representations and warranties and other agreements are customarily made by issuers to selling stockholders in secondary underwritten public offerings, and the Holders shall be required to make representations or warranties to, and other agreements
with, the Company and the underwriters in connection with such underwriting agreement as are customarily made by selling stockholders in secondary underwritten public offerings; provided, however, that the Holders shall not be required
to make 

  
 3 








 
any representations or warranties to the Company or the underwriters regarding such Holder’s knowledge about the Company or to undertake any indemnification obligations to the Company with
respect thereto, except as otherwise provided in Article III), or to the underwriters with respect thereto, except to the extent of the indemnification being given to the Company and its controlling Persons in Article III. 

(d) If (i) the managing underwriter for such Underwritten Offering advises the Company or (ii) the Company concludes, after
consulting with its independent financial advisor (which shall be an investment banking firm of international standing), in either case, that in its opinion the number of Registrable Securities requested to be included in such Underwritten Offering
exceeds the number of Registrable Securities that can be sold in an orderly manner in such offering within a price range acceptable to the Holders, the Company shall include in such Underwritten Offering the number of each Holder’s Registrable
Securities which in the opinion of such managing underwriter or the Company’s independent financial advisor, as applicable, can be sold in an orderly manner within the price range of such offering. 

(e) Unless the managing underwriter otherwise agrees, each Holder agrees not to effect any public sale or private offer or distribution of any
shares of Company Common Stock or any other issue being registered or a similar security of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the fourteen (14) days prior to the anticipated
effectiveness under the Securities Act of any underwritten registration of any such securities (or with respect to an underwritten takedown of any such securities under a shelf registration, prior to the pricing of such offer) and during such time
period (not to exceed one hundred eighty (180) days) after the effectiveness under the Securities Act of any underwritten registration (or, with respect to an underwritten offering pursuant to a shelf registration statement, after the pricing of
such offering) as the Company and the managing underwriter may agree (except as part of such underwritten registration or offering, as applicable). 

2.2 Registration Procedures. If and whenever a Holder has requested that any Registrable Securities be registered pursuant to
this Agreement under Article I, and subject to the limitations set forth in this Agreement, the Company will use its commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof, and pursuant thereto the Company will: 
 (a) if the Registration Statement is not automatically
effective upon filing, use commercially reasonable efforts to cause such Registration Statement to become effective; 
 (b) notify such
Holder, promptly after the Company receives notice thereof, of the time when such Registration Statement has been declared effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed; 

(c) after the Registration Statement becomes effective, notify such Holder of any request by the SEC that the Company amend or supplement such
Registration Statement or Prospectus; 
 (d) prepare and file with the SEC such amendments and supplements to the Registration Statement and
any Prospectus used in connection therewith as may be reasonably necessary to keep the Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by
the Registration Statement for the period required to effect the distribution of the Registrable Securities as set forth in Article I hereof; 

(e) to the extent necessary to properly sell any Registrable Securities, furnish to such Holder such numbers of copies of a Prospectus,
including a preliminary Prospectus, as required by the Securities Act, and such other documents as such Holder may reasonably request in order to facilitate its disposition of its Registrable Securities; 

  
 4 








 (f) use its commercially reasonable efforts to register and qualify the Registrable Securities
under such other securities or blue sky Laws of such jurisdictions as shall be reasonably requested by such Holder; provided, however, that the Company shall not be required in connection therewith or as a condition thereto
to qualify to do business in or to file a general consent to service of process in any jurisdiction, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act, or subject itself to
taxation in any such jurisdiction, unless the Company is already subject to taxation in such jurisdiction; 
 (g) use its commercially
reasonable efforts to cause all such Registrable Securities to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar equity securities issued by the Company are then
listed; 
 (h) provide a transfer agent and registrar for the Registrable Securities and provide a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of the Registration Statement; 
 (i) use its commercially reasonable efforts to
furnish, on the date that shares of Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for
the purposes of such registration, in form and substance as is customarily given to underwriters by the Company in an underwritten public offering, addressed to the underwriters and (ii) a letter dated as of such date, from the independent
public accountants of the Company, in form and substance as is customarily given by independent public accountants to underwriters in an underwritten public offering, addressed to the underwriters; 

(j) if requested by such Holder, cooperate with such Holder and the managing underwriter (if any) to facilitate the timely preparation and
delivery of certificates (which shall not bear any restrictive legends unless required under applicable Law) representing securities sold under the Registration Statement, and enable such securities to be in such denominations and registered in such
names as such Holder or the managing underwriter (if any) may request and keep available and make available to the Company’s transfer agent prior to the effectiveness of such Registration Statement a supply of such certificates; 

(k) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in form and
substance as is customarily given by the Company to underwriters in an underwritten public offering, with the underwriter(s) of such offering; 

(l) upon execution of confidentiality agreements in form and substance satisfactory to the Company, promptly make available for inspection by
such Holder, any underwriter(s) participating in any disposition pursuant to such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by such Holder, all financial and other records,
pertinent corporate documents, and properties of the Company (collectively, “Records”), and use commercially reasonable efforts to cause the Company’s officers, directors, employees, and independent accountants to supply all
information reasonably requested by such Holder, an underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such Registration Statement and to conduct appropriate due
diligence in connection therewith; provided, Records that the Company determines, in good faith, to be confidential and that it notifies such Holder are confidential shall not be disclosed by such Holder unless the release of such
Records is ordered pursuant to a subpoena or 

  
 5 








 
other order from a court of competent jurisdiction or is otherwise required by applicable Law. Such Holder agrees that information obtained by it as a result of such inspections shall be deemed
confidential and shall not be used by it or its Affiliates (other than with respect to such Holder’s due diligence) unless and until such information is made generally available to the public, and further agrees that, upon learning that
disclosure of such Records is sought in a court of competent jurisdiction, it shall give notice to the Company and allow the Company to undertake appropriate action to prevent disclosure of the Records deemed confidential; 

(m) in the event of the issuance of any stop order suspending the effectiveness of such Registration Statement, or of any order suspending or
preventing the use of any related Prospectus or suspending the qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction, use its commercially reasonable efforts to obtain promptly the
withdrawal of such order; 
 (n) promptly notify such Holder at any time when a Prospectus relating thereto is required to be delivered under
the Securities Act of the happening of any event as a result of which the Prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, and at the request of such Holder promptly prepare and furnish to such Holder a reasonable number of copies of a supplement
to or an amendment of such Prospectus, or a revised Prospectus, as may be necessary so that, as thereafter delivered to the purchasers of such securities, such Prospectus shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made (following receipt of any supplement or amendment to any Prospectus, such Holder shall
deliver such amended, supplemental or revised Prospectus in connection with any offers or sales of Registrable Securities, and shall not deliver or use any Prospectus not so supplemented, amended or revised); and 

(o) take all such other actions as are reasonably necessary in order to facilitate the disposition of such Registrable Securities. 

2.3 Holder Obligations. Subject to Section 2.1(a), a Holder may not participate in any registration hereunder unless
such Holder: (i) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Company; and (ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents, each in customary form, reasonably required under the terms of such underwriting arrangements; provided, however, that such Holder shall not be required to make any representations or
warranties in connection with any such registration other than representations and warranties as to (A) such Holder’s ownership of its Registrable Securities to be sold or transferred free and clear of all liens, claims and encumbrances;
(B) such Holder’s power and authority to effect such transfer; and (C) such matters pertaining to compliance with securities Laws as may be reasonably requested; provided, further, that such liability will be limited, to
the net amount received by such Holder from the sale of its Registrable Securities pursuant to such registration. 
 2.4 Blackout
Periods. 
 (a) (i) At any time when a Registration Statement effected pursuant to Article I relating to Registrable
Securities is effective, upon written notice from the Company to a Holder that the board of directors of the Company (or any duly appointed committee thereof) has determined in good faith, with the advice of counsel, that such Holder’s sale of
Registrable Securities pursuant to the Registration Statement would be reasonably likely to require disclosure of material non-public information 

  
 6 








 
the disclosure of which would not otherwise be required to be disclosed (provided that the Company shall not be required to disclose to such Holder any such material non-public information) and
would be reasonably likely to have a material adverse effect on the Company or that such sale otherwise might not be in the best interests of the Company’s stockholders (an “Information Blackout”), such Holder shall suspend
sales of Registrable Securities pursuant to such Registration Statement and (ii) if, while a Registration Request Notice or other registration request is pending pursuant to Article I, the board of directors of the Company (or any duly
appointed committee thereof) determines that an Information Blackout is required, or that any such filing or the offering of any Registrable Securities would be reasonably likely to adversely affect or delay any proposed financing, offer or sale of
securities, acquisition, disposition, corporate reorganization or other material transaction involving the Company, the Company shall deliver to such Holder a certificate to such effect signed by its Chief Executive Officer or Chief Financial
Officer, and the Company shall not be required to file a Registration Statement, Prospectus or any amendment or any supplement thereto pursuant to Articles I (a “Registration Delay”); provided, that any such suspension
or postponement under (i) and (ii) of this Section 2.4(a) shall only continue until the earliest of: 
 (1) the date
upon which such material information is disclosed to the public or ceases to be material; 
 (2) ten (10) days after the Company’s
delivery of such written notice to such Holder; 
 (3) in the case of clause (i) above, such time as the Company notifies such Holder
that sales pursuant to such Registration Statement may be resumed; and 
 (4) in the case of clause (ii) above, the date upon which the
financing, offer or sale of securities, acquisition, corporate reorganization or other material transaction referred to therein concludes or is abandoned. 

The number of days from such suspension of sales by a Holder until the day when such sales may be resumed under clause (1), (2) or (3) hereof, or
from the date of a notice of a Registration Delay until the date such affected registration process resumes under clause (1), (2) or (4) hereof, shall be called a “Blackout Period”. In no event may the Company deliver more
than two (2) notices, collectively, of an Information Blackout and/or a Registration Delay in any twelve (12) consecutive month period, and the aggregate number of days in which any Blackout Periods may be in effect in any twelve
(12) consecutive month period shall not exceed one hundred twenty (120) days. 
 (b) Any delivery by the Company of a written
notice of a Registration Delay following a registration request by a Holder pursuant to Section 1.1, and before the effectiveness of the related Registration Statement, or of a written notice of an Information Blackout during the sixty
(60) days immediately following effectiveness of any Registration Statement effected pursuant to Article I, shall give such Holder the right, by written notice to the Company within twenty (20) Business Days after the end of such

thereof; provided, however, that (a) such Holder shall give the Company written notice prior to the time of such transfer stating the name and address of the

(i) use its commercially reasonable efforts to file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder; and
(ii) make available information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, all to the extent required from time to time to enable
each Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule 144A promulgated under the Securities Act (if available with respect to resales
of the Registrable Securities), as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC. 

ARTICLE III – INDEMNIFICATION 

3.1 Indemnification. 

(a) The Company agrees to indemnify and reimburse, to the fullest extent permitted by Law, each Holder, with respect to the sale of Registrable
Securities pursuant hereto, and each of its employees, advisors, agents, representatives, partners, officers, and directors and each Person who controls such Holder (within the meaning of the Securities Act or the Exchange Act) and any agent or
investment advisor thereof (collectively, the “Seller Affiliates”): (i) against any and all losses, claims, damages, liabilities and expenses, joint or several (including, without limitation, attorneys’ fees and
disbursements except as limited by Section 3.1(c)) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment
thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) against any and all losses, liabilities, claims, damages and
expenses whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon, arising
out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission; and (iii) against any and all costs and expenses (including reasonable fees and disbursements of counsel) as may be reasonably
incurred in investigating, preparing or defending against any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon, arising out of, related to or resulting from any
such untrue statement or omission or alleged untrue statement or omission, or such violation of the Securities Act or Exchange Act, to the extent that any such expense or cost is not paid under subparagraph (i) or (ii) above; except
insofar as any such statements are made in reliance upon information furnished to the Company by a Holder or any Seller Affiliate for use therein or arise from a Holder’s or any Seller Affiliate’s failure to deliver a copy of the
Registration Statement or Prospectus or any amendments or supplements thereto after the Company has furnished such Holder or its Seller Affiliate with a sufficient number of copies of the same, in which case the Company will not so indemnify and
reimburse such Holder or its Seller Affiliates. The reimbursements required by this Section 3.1(a) will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred.


  
 8 








 (b) In connection with any Registration Statement in which a Holder is participating as a seller
of Registrable Securities, such Holder will furnish to the Company such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the fullest extent permitted by
Law, such Holder will indemnify the Company and its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) against any and all losses, claims, damages, liabilities and expenses
(including, without limitation, reasonable attorneys’ fees and disbursements except as limited by Section 3.1(c)) resulting from any untrue statement or alleged untrue statement of a material fact contained in the Registration
Statement, Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission is contained in any information or affidavit so furnished by such Holder or any of its Seller Affiliates specifically for inclusion in the Registration Statement;
provided that such liability will be limited to the net amount received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement; provided, however, that such Holder shall not be liable in
any such case to the extent that prior to the filing of any such Registration Statement or Prospectus or amendment thereof or supplement thereto, such Holder has furnished to the Company information expressly for use in such Registration Statement
or Prospectus or any amendment thereof or supplement thereto which corrected or made not misleading information previously furnished to the Company. 

(c) Any Person entitled to indemnification hereunder will: (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks indemnification (provided that the failure to give such notice shall not limit the rights of such Person); and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any
person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (A) the
indemnifying party has agreed to pay such fees or expenses or (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person. If such defense is not assumed by the
indemnifying party as permitted hereunder, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed).
If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (i) such settlement or compromise contains a full and
unconditional release of the indemnified party or (ii) the indemnified party otherwise consents in writing (which consent will not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not
to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified
party, a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of
such additional counsel or counsels. 
 (d) Each party hereto agrees that, if for any reason the indemnification provisions contemplated by
Section 3.1(a) or Section 3.1(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by 

  
 9 








 
such indemnified party as a result of such losses, claims, liabilities or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the
indemnifying party and the indemnified party in connection with the actions which resulted in the losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party
and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such
indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 3.1(d) were determined by pro rata allocation (even if a Holder or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 3.1(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof)
referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 3.1(c), defending any such action or claim.
Notwithstanding the provisions of this Section 3.1(d), no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such Holder with respect to the sale of any Registrable
Securities exceeds the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any Registration
Statement or Prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Securities. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Each Holder’s obligations in this Section 3.1(d) to contribute shall be several in proportion to the amount of Registrable Securities
registered by them and not joint. 
 If indemnification is available under this Section 3.1, the indemnifying parties shall
indemnify each indemnified party to the full extent provided in Section 3.1(a) and Section 3.1(b) without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration
provided for in this Section 3.1(d) subject, in the case of a Holder, to the limited dollar amounts set forth in Section 3.1(b). 

(e) The indemnification and contribution provided for under this Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities. 

ARTICLE IV – TERMINATION 

4.1 Termination. The provisions of this Agreement shall terminate and be of no further force and effect upon the earlier of
(a) the four (4) year anniversary following the Closing and (b) the date when all Registrable Securities have been sold or are available to be sold under Rule 144 promulgated under the Securities Act without regard to volume limits.

 ARTICLE V – MISCELLANEOUS 

5.1 Amendment. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing

5.3 Governing Law; Submission to Jurisdiction; Waiver of Jury Trial.

the conflicts of law rules of such State that would result in the application of any Law other than the Law of the State of Delaware.

of any process, summons, notice or document by U.S. registered mail, or otherwise in the manner provided for notices in Section 3.5 hereof, shall be effective service of process for any such proceeding brought against it in any such
court, (iv) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding in such courts and (v) agrees not to plead or claim in any court
that any such proceeding brought in any such court has been brought in an inconvenient forum. Each of the parties hereto agrees that a final judgment in any such proceeding shall be conclusive and may be enforced in other jurisdictions by suit on
the judgment or in any other manner provided by applicable Law. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by applicable Law. 

(c) THE PARTIES HERETO WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING
(WHETHER BASED ON CONTRACT, EQUITY, TORT OR ANY OTHER THEORY) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTION AGREEMENT, OR THE NEGOTIATION, EXECUTION, PERFORMANCE, OR ENFORCEMENT OF THIS AGREEMENT, THE
TRANSACTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, REGARDLESS OF WHICH PARTY INITIATES SUCH ACTION OR PROCEEDING. EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

 Reference is made to the base indenture, dated as of

which the Notes were issued.
 The undersigned Beneficial Owner (as defined below) hereby represents and warrants that the undersigned is the Beneficial
Owner of the Notes of the above-referenced issue in the principal amount stated below. At the request of Participant, on behalf of the undersigned Beneficial Owner of the Notes, Cede & Co., as the registered Holder of the Notes, hereby
