 2. Registration. 

(a) Demand Registration. 

(i) At any time after the expiration of the Lock-Up Period, any Sponsoring Holder shall have the
option and right, exercisable by delivering a written notice to the Company (a “Demand Notice”), to require the Company to, pursuant to the terms of and subject to the limitations contained in this Agreement, prepare and file
with the Commission a Registration Statement registering the offering and sale of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice, which may include sales on a delayed or continuous basis
pursuant to Rule 415 pursuant to a Shelf Registration Statement (a “Demand Registration”). The Demand Notice must set forth the number of Registrable Securities that the Initiating Holder intends to include in such
Demand Registration and the intended methods of disposition thereof. Notwithstanding anything to the contrary herein, in no event shall the Company be required to effectuate a Demand Registration unless the Registrable Securities of the Holders to
be included therein after compliance with Section 2(a)(ii) have an aggregate value, based on the VWAP as of the date of the Demand Notice, of at least $50 million (the “Minimum Amount”). 

(ii) Within five Business Days (or if the Registration Statement will be a Shelf Registration Statement, within two Business Days) after the
receipt of the Demand Notice, the Company shall give written notice of such Demand Notice to all Holders and, within 30 days after receipt of the Demand Notice (except if the Company is not then eligible to register for

  
 5 

 
resale the Registrable Securities on Form S-3, in which case, within 90 days thereof), shall, subject to the limitations of this Section 2(a), file
a Registration Statement in accordance with the terms and conditions of the Demand Notice, which Registration Statement shall cover all of the Registrable Securities that the Holders shall in writing request to be included in the Demand Registration
(such request to be given to the Company within three Business Days (or if the Registration Statement will be a Shelf Registration Statement, within one Business Day) after receipt of notice of the Demand Notice given by the Company pursuant to this
Section 2(a)(ii)). The Company shall use reasonable best efforts to cause such Registration Statement to become and remain effective under the Securities Act until the earlier of (A) 180 days (or two years if a Shelf Registration Statement is
requested) after the Effective Date or (B) the date on which all Registrable Securities covered by such Registration Statement have been sold (the “Effectiveness Period”); provided, however, that such
period shall be extended for a period of time equal to the period the Holders refrain from selling any securities included in such Registration Statement at the request of an underwriter of the Company or the Company pursuant to this Agreement. 

(iii) Subject to the other limitations contained in this Agreement, the Company is not obligated hereunder to effect (A) a Demand
Registration within 90 days after the closing of any Underwritten Offering, (B) more than a total of three Demand Registrations for which GSO (or any transferee thereof in accordance with Section 9(e)) is the Initiating Holder or
(C) a subsequent Demand Registration pursuant to a Demand Notice if a Registration Statement covering all of the Registrable Securities held by the Initiating Holder shall have become and remains effective under the Securities Act and is
sufficient to permit offers and sales of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice in accordance with the intended timing and method or methods of distribution thereof specified in the
Demand Notice. No Demand Registration shall be deemed to have occurred for purposes of this Section 2(a)(iii) if the Registration Statement relating thereto does not become effective or is not maintained effective for
its entire Effectiveness Period, in which case the Initiating Holder shall be entitled to an additional Demand Registration in lieu thereof. 

(iv) A Holder may withdraw all or any portion of its Registrable Securities included in a Demand Registration from such Demand Registration at
any time prior to the effectiveness of the applicable Registration Statement. Upon receipt of a notice from the Initiating Holder that the Initiating Holder is withdrawing all of its Registrable Securities from the Demand Registration or a notice
from a Holder to the effect that the Holder is withdrawing an amount of its Registrable Securities such that the remaining amount of Registrable Securities to be included in the Demand Registration is below the Minimum Amount, the Company shall
cease all efforts to secure effectiveness of the applicable Registration Statement. Such registration nonetheless shall be deemed a Demand Registration with respect to the Initiating Holder for purposes of
Section 2(a)(iii) unless (A) the Initiating Holder shall have paid or reimbursed the Company for its pro rata share of all reasonable and documented
out-of-pocket fees and expenses incurred by the Company in connection with the withdrawn registration of such Registrable Securities (based on the number of securities
the Initiating Holder sought to register, as compared to the total number of securities included in such Demand Registration) or (B) the withdrawal is made following the occurrence of a Material Adverse Change or pursuant to the Company’s
request for suspension pursuant to Section 3(o). 

  
 6 

 (v) The Company may include in any such Demand Registration other Company Securities for sale for
its own account or for the account of any other Person, subject to Section 2(a)(vi) and Section 2(c)(iii). 

(vi) In the case of a Demand Registration not being underwritten, if the Initiating Holder advises the Company that in its reasonable opinion
the aggregate number of securities requested to be included exceeds the number that can be included without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the
securities offered, the Company shall include in such Demand Registration only that number of securities that in the reasonable opinion of the Initiating Holder will not have such adverse effect, with such number to be allocated as follows:
(A) first, pro-rata among all Holders (including the Initiating Holder) that have requested to participate in such Demand Registration based on the relative number of Registrable Securities then held by
each such Holder, (B) second, if there remains availability for additional securities to be included in such Demand Registration, the Company, and (C) third, if there remains availability for additional securities to be included in such
Demand Registration, any other holders entitled to participate in such Demand Registration, if applicable, based on the relative number of securities such Holder is entitled to include in such Demand Registration. 

(vii) Subject to the limitations contained in this Agreement, the Company shall effect any Demand Registration on such appropriate
registration form of the Commission (A) as shall be selected by the Company and (B) as shall permit the disposition of the Registrable Securities in accordance with the intended method or methods of disposition specified in the Demand
Notice; provided that if the Company becomes, and is at the time of its receipt of a Demand Notice, eligible to file a Shelf Registration Statement, the Demand Registration for any offering and selling of Registrable Securities shall be
effected pursuant to a Shelf Registration Statement; provided further that if the Company becomes, and is at the time of its receipt of a Demand Notice, a WKSI, the Demand Registration for any offering and selling of Registrable Securities
shall be effected pursuant to an Automatic Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if available to the Company). If at any
time a Registration Statement on Form S-3 is effective and a Holder provides written notice to the Company that it intends to effect an offering of all or part of the Registrable Securities included on
such Registration Statement, the Company will amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place. 

(viii) Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with
this Section 2(a), the Company shall (A) promptly prepare and file or cause to be prepared and filed (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other
documents, as may be necessary or advisable to register or qualify the securities subject to such Demand Registration, including under the securities laws of such jurisdictions as the Holders shall reasonably request; provided,
however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Company would become subject to general service of process or to taxation or qualification to do business in such jurisdiction solely as
a result of registration and (2) such forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to

  
 7 

 
such Demand Registration on the Trading Market and (B) do any and all other acts and things that may be reasonably necessary or appropriate or reasonably requested by the Holders to enable
the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution thereof. 

(ix) In the event a Holder transfers Registrable Securities included on a Registration Statement and such Registrable Securities remain
Registrable Securities following such transfer, at the request of such Holder, the Company shall amend or supplement such Registration Statement as may be necessary in order to enable such transferee to offer and sell such Registrable Securities
pursuant to such Registration Statement; provided that in no event shall the Company be required to file a post-effective amendment to the Registration Statement unless (A) such Registration Statement includes only Registrable Securities
held by the Holder, Affiliates of the Holder or transferees of the Holder or (B) the Company has received written consent therefor from a Person for whom Registrable Securities have been registered on (but not yet sold under) such Registration
Statement, other than the Holder, Affiliates of the Holder or transferees of the Holder. 
 (b) Requested Underwritten
Offering. Any Sponsoring Holder then able to effectuate a Demand Registration pursuant to the terms of Section 2(a), ignoring for purposes of such determination Section 2(a)(iii)(B), or any
Sponsoring Holder who has previously effectuated a Demand Registration pursuant to Section 2(a) but has not engaged in an Underwritten Offering in respect of such Demand Registration, shall have the option and right,
exercisable by delivering written notice to the Company of its intention to distribute Registrable Securities by means of an Underwritten Offering (an “Underwritten Offering Notice”), to require the Company, pursuant to the
terms of and subject to the limitations of this Agreement, to effectuate a distribution of any or all of its Registrable Securities by means of an Underwritten Offering pursuant to a new Demand Registration or pursuant to an effective Registration
Statement covering such Registrable Securities (a “Requested Underwritten Offering”); provided, that if the Requested Underwritten Offering is pursuant to a new Demand Registration, then the Registrable Securities of
such Initiating Holder requested to be included in such Requested Underwritten Offering have an aggregate value at least equal to the Minimum Amount as of the date of such Underwritten Offering Notice, and if the Requested Underwritten Offering is
pursuant to an effective Demand Registration, then the Registrable Securities of such Initiating Holder requested to be included in such Requested Underwritten Offering have an aggregate value at least equal to 50 percent of the Minimum Amount
as of the date of such Underwritten Offering Notice. The Underwritten Offering Notice must set forth the number of Registrable Securities that the Initiating Holder intends to include in such Requested Underwritten Offering. The managing underwriter
or managing underwriters of a Requested Underwritten Offering shall be designated by the Company; provided, however, that such designated managing underwriter or managing underwriters shall be reasonably acceptable to the Initiating
Holder. Notwithstanding the foregoing, the Company is not obligated to effect a Requested Underwritten Offering within 90 days after the closing of an Underwritten Offering. Any Requested Underwritten Offering (other than the first Requested
Underwritten Offering made in respect of a prior Demand Registration) shall constitute a Demand Registration of the Initiating Holder for purposes of Section 2(a)(iii) (it being understood that if requested
concurrently with a Demand Registration then, together, such Demand Registration and Requested Underwritten Offering shall count as one Demand Registration); provided, however, 

  
 8 

 
that a Requested Underwritten Offering shall not constitute a Demand Registration of the Initiating Holder for purposes of Section 2(a)(iii) if, as a result of
Section 2(c)(iii)(A), the Requested Underwritten Offering includes less than the lesser of (i) Registrable Securities of the Initiating Holder having an aggregate value, based on the VWAP as of the Effective Date of
the related Registration Statement, of $30 million, and (ii) two-thirds of the number of Registrable Securities the Initiating Holder set forth in the applicable Underwritten Offering Notice. 

(c) Piggyback Registration and Piggyback Underwritten Offering. 

(i) If the Company shall at any time propose to file a registration statement under the Securities Act with respect to an offering of Common
Stock (other than a registration statement on Form S-4, Form S-8 or any successor forms thereto or filed solely in connection with an exchange offer or any
employee benefit or dividend reinvestment plan and other than a Demand Registration), whether or not for its own account, then the Company shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five
Business Days except if the registration statement will be a Shelf Registration Statement, at least two Business Days, before) the anticipated filing date (the “Piggyback Registration Notice”). The Piggyback Registration
Notice shall offer Holders the opportunity to include for registration in such registration statement the number of Registrable Securities as they may request in writing (a “Piggyback Registration”). The Company shall use
commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which the Company has received written requests for inclusion therein (“Piggyback Registration Request”) within
three Business Days or, if the Piggyback Registration will be on a Shelf Registration Statement, at least two Business Days, after sending the Piggyback Registration Notice; provided, however, that the Company shall not be required to
include in such Piggyback Registration a Holder’s Registrable Securities in the event such Holder, together with its Affiliates, does not request for inclusion Registrable Securities having an aggregate value, based on the VWAP as of the date
of the Piggyback Registration Notice, of at least $10 million. Each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration by giving written notice to the Company of its
request to withdraw; provided that (A) such request must be made in writing prior to the effectiveness of such registration statement and (B) such withdrawal shall be irrevocable and, after making such withdrawal, a Holder shall no longer
have any right to include Registrable Securities in the Piggyback Registration as to which such withdrawal was made. Any withdrawing Holder shall continue to have the right to include any Registrable Securities in any subsequent registration
statement or registration statements as may be filed by the Company with respect to offerings of Common Stock, all upon the terms and conditions set forth herein. 

(ii) If the Company shall at any time propose to conduct an Underwritten Offering (including a Requested Underwritten Offering), whether or
not for its own account, then the Company shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days before or two Business Days before in connection with a “bought deal” or
overnight Underwritten Offering) the commencement of the offering, which notice shall set forth the principal terms and conditions of the issuance, including the proposed offering price or range of offering prices (if known), the anticipated filing
date of the related registration statement (if applicable) and the number of shares of Common Stock that are proposed to be registered (the “Underwritten Offering Piggyback Notice”). The Underwritten

  
 9 

 
Offering Piggyback Notice shall offer Holders the opportunity to include in such Underwritten Offering (and any related registration, if applicable) the number of Registrable Securities as they
may request in writing (an “Underwritten Piggyback Offering”); provided, however, that in the event that the Company proposes to effectuate the subject Underwritten Offering pursuant to an effective Shelf
Registration Statement of the Company other than an Automatic Shelf Registration Statement, only Registrable Securities of Holders which are subject to an effective Shelf Registration Statement may be included in such Underwritten Piggyback
Offering. The Company shall use commercially reasonable efforts to include in each such Underwritten Piggyback Offering such Registrable Securities for which the Company has received written requests for inclusion therein (“Underwritten
Offering Piggyback Request”) within three Business Days after sending the Underwritten Offering Piggyback Notice (or one Business Day in connection with a “bought deal” or overnight Underwritten Offering); provided,
however, that the Company shall not be required to include in such Underwritten Piggyback Offering a Holder’s Registrable Securities in the event such Holder, together with its Affiliates, does not request for inclusion Registrable
Securities having an aggregate value, based on the VWAP as of the date of the Underwritten Offering Piggyback Notice, of at least $10 million. Notwithstanding anything to the contrary in this Section 2(c)(ii), if the
Underwritten Offering pursuant to this Section 2(c)(ii) is a “bought deal” or overnight Underwritten Offering and the managing underwriter advises the Company that the giving of notice pursuant to this
Section 2(c)(ii) would adversely affect the Underwritten Offering, no such notice shall be required. Each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from an
Underwritten Piggyback Offering at any time prior to the effectiveness of the applicable registration statement, and such Holder shall continue to have the right to include any Registrable Securities in any subsequent Underwritten Offerings, all
upon the terms and conditions set forth herein. Notwithstanding anything to the contrary in this Agreement, no Holder (other than GSO and its Affiliates and their respective successors and assigns) shall have the right to make an Underwritten
Offering Piggyback Request unless the contemplated plan of distribution of such Underwritten Offering includes a customary “road show” or other marketing effort by the Company and the underwriters. 

(iii) If the managing underwriter or managing underwriters of an Underwritten Offering advise the Company and the Holders that in their
reasonable opinion that the inclusion of all of the Holders’ Registrable Securities requested for inclusion in the subject Underwritten Offering (and any related registration, if applicable) (and any other Common Stock proposed to be included
in such offering) exceeds the number that can be included without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, the Company shall include in
such Underwritten Offering (and any related registration, if applicable) only that number of shares of Common Stock proposed to be included in such Underwritten Offering (and any related registration, if applicable) that, in the reasonable opinion
of the managing underwriter or managing underwriters, will not have such adverse effect, with such number to be allocated as follows: (A) in the case of a Requested Underwritten Offering, (1) first, to the Initiating Holder in full with
respect to the number of Registrable Securities such Initiating Holder requested for inclusion, (2) second, pro-rata among all Holders (other than the Initiating Holder) that have requested to include
Registrable Securities in such Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder, (3) third, if there remains availability for additional shares of Common Stock to be included in such
Underwritten 

  
 10 

 
Offering, to the Company, and (4) fourth, if there remains availability for additional shares of Common Stock to be included in such Underwritten Offering, to any other holders entitled to
participate in such Underwritten Offering, if applicable, based on the relative number of shares of Common Stock then held by each such Holder; and (B) in the case of any other Underwritten Offerings, (x) first, to the Company,
(y) second, if there remains availability for additional shares of Common Stock to be included in such Underwritten Offering, pro-rata among all Holders desiring to include Registrable Securities in such
Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder, and (z) third, if there remains availability for additional shares of Common Stock to be included in such registration, pro-rata among any other holders entitled to participate in such Underwritten Offering, if applicable, based on the relative number of Common Stock then held by each such Holder. If any Holder disapproves of the
terms of any such Underwritten Offering, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering. Any Registrable
Securities withdrawn from such underwriting shall be excluded and withdrawn from the registration. 
 (iv) The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 2(c) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration
Statement. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 4 hereof. 

3. Registration and Underwritten Offering Procedures. 

The procedures to be followed by the Company and each Holder electing to sell Registrable Securities in a Registration Statement pursuant to
this Agreement, and the respective rights and obligations of the Company and such Holders, with respect to the preparation, filing and effectiveness of such Registration Statement and the effectuation of any Underwritten Offering, are as follows:

Registration Statement or related Prospectus or amendment or supplement thereto that identify the Holders and any related Prospectus or any amendment or supplement thereto (other 

  
 11 

 
than amendments and supplements that do not materially alter the previous disclosure or do nothing more than name Holders and provide information with respect thereto) prior to filing and
(ii) use commercially reasonable efforts to address in each such document when so filed with the Commission such comments as such Holders reasonably shall propose prior to the filing thereof. 

(c) The Company will use commercially reasonable efforts to as promptly as reasonably practicable (i) prepare and file with the
Commission such amendments, including post-effective amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary under applicable law to keep such Registration Statement continuously
effective with respect to the disposition of all Registrable Securities covered thereby for its Effectiveness Period and, subject to the limitations contained in this Agreement, prepare and file with the Commission such additional Registration
Statements in order to register for resale under the Securities Act all of the Registrable Securities held by the Holders; (ii) cause the related Prospectus to be amended or supplemented by any required prospectus supplement, and as so
supplemented or amended to be filed pursuant to Rule 424; and (iii) respond to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably practicable
provide such Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to such Holders as selling stockholders but not any comments that would result in the disclosure to
such Holders of material and non-public information concerning the Company. 
 (d) The Company will
comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statements and the disposition of all Registrable Securities covered by each Registration Statement. 

(e) The Company will notify such Holders who are included in a Registration Statement as promptly as reasonably practicable:
(i) (A) when a Prospectus or any prospectus supplement or post-effective amendment to a Registration Statement in which such Holder is included has been filed; (B) when the Commission notifies the Company whether there will be a
“review” of the applicable Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case the Company shall provide true and complete copies thereof and all written responses thereto to
each of such Holders that pertain to such Holders as selling stockholders); and (C) with respect to each applicable Registration Statement or any post-effective amendment thereto, when the same has been declared effective; (ii) of any
request by the Commission or any other federal or state governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information that pertains to such Holders as sellers of Registrable
Securities; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of such Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose;
(iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of
any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such 

  
 12 

 
Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (provided, however, that no notice by the Company shall be required pursuant to this clause (v) in the
event that the Company either promptly files a prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration
Statement, which in either case, contains the requisite information that results in such Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading). 
 (f) The Company will use commercially reasonable efforts
to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction, as promptly as reasonably practicable, or if any such order or suspension is made effective during any Blackout Period or Suspension Period, as promptly as reasonably practicable after such
Blackout Period or Suspension Period is over. 
 (g) During the Effectiveness Period, the Company will furnish to each such Holder, without
charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Holder (including those incorporated by reference) promptly after the filing of such documents with the
Commission; provided, that the Company will not have any obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 

(h) The Company will promptly deliver to each Holder, without charge, as many copies of each Prospectus or Prospectuses (including each form
of Prospectus) authorized by the Company for use and each amendment or supplement thereto as such Holder may reasonably request during the Effectiveness Period. Subject to the terms of this Agreement, including
Section 9(b), the Company consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such
Prospectus and any amendment or supplement thereto. 
 (i) The Company will cooperate with such Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable Securities are
unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in
writing. In connection therewith, if required by the Company’s transfer agent, the Company will promptly, after the Effective Date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement
to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to issue such Registrable Securities without
any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement. 

  
 13 

 (j) Upon the occurrence of any event contemplated by Section 3(e)(v),
as promptly as reasonably practicable, the Company will prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration Statement or a supplement to the related Prospectus or any
document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain 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, in the light of the circumstances under which they were made, not misleading. 

(k) With respect to Underwritten Offerings, (i) the right of any Holder to include such Holder’s Registrable Securities in an
Underwritten Offering shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (ii) each Holder
participating in such Underwritten Offering agrees to enter into an underwriting agreement in customary form and sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled
to select the managing underwriter or managing underwriters hereunder and (iii) each Holder participating in such Underwritten Offering agrees to complete and execute all questionnaires, powers of attorney, indemnities, underwriting agreements
and other documents customarily and reasonably required under the terms of such underwriting arrangements. The Company hereby agrees with each Holder that, in connection with any Underwritten Offering in accordance with the terms hereof, it will
negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using all commercially reasonable efforts to procure customary legal
opinions, auditor “comfort” letters and reports of the independent petroleum engineers of the Company relating to the oil and gas reserves of the Company included in the Registration Statement if the Company has had its reserves prepared,
audited or reviewed by an independent petroleum engineer. 
 (l) For a reasonable period prior to the filing of any Registration Statement
and throughout the Effectiveness Period, the Company will make available, upon reasonable notice at the Company’s principal place of business or such other reasonable place, for inspection during normal business hours by a representative or
representatives of the selling Holders, the managing underwriter or managing underwriters and any attorneys or accountants retained by such selling Holders or underwriters, all such financial and other information and books and records of the
Company, and cause the officers, employees, counsel and independent certified public accountants of the Company to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in
such counsel’s reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that any information that is not generally publicly available at the time of
delivery of such information shall be kept confidential by such Persons unless disclosure of such information is required by court or administrative order or, in the opinion of counsel to such Person, law, in which case, such Person shall be
required to give the Company written notice of the proposed disclosure prior to such disclosure and, if requested by the Company, assist the Company in seeking to prevent or limit the proposed disclosure. 

  
 14 

 (m) In connection with any Requested Underwritten Offering, the Company will use commercially
reasonable efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road shows. 

(n) Each Holder agrees to furnish to the Company any other information regarding the Holder and the distribution of such securities as the
Company reasonably determines is required to be included in any Registration Statement or any Prospectus or prospectus supplement relating to an Underwritten Offering. 

(o) Notwithstanding any other provision of this Agreement, the Company shall not be required to file a Registration Statement (or any
amendment thereto) or effect a Requested Underwritten Offering (or, if the Company has filed a Shelf Registration Statement and has included Registrable Securities therein, the Company shall be entitled to suspend the offer and sale of Registrable
Securities pursuant to such Registration Statement) for a period of up to 60 days if (i) the Board determines that a postponement is in the best interest of the Company and its stockholders generally due to a pending transaction involving the
Company (including a pending securities offering by the Company), (ii) the Board determines such registration would render the Company unable to comply with applicable securities laws or (iii) the Board determines such registration would
require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential (any such period, a “Blackout Period”). Notwithstanding anything to the contrary in this
Agreement, in no event shall any Blackout Periods and any Suspension Periods continue for more than 120 days in the aggregate during any 12-month period. 

(p) In connection with an Underwritten Offering, the Company shall use all commercially reasonable efforts to provide to each Holder named as
a selling securityholder in any Registration Statement a copy of any auditor “comfort” letters, customary legal opinions or reports of the independent petroleum engineers of the Company relating to the oil and gas reserves of the Company,
in each case that have been provided to the managing underwriter or managing underwriters in connection with the Underwritten Offering, not later than the Business Day prior to the Effective Date of such Registration Statement. 

4. No Inconsistent Agreements; Additional Rights. The Company shall not hereafter enter into, and is not currently a party to, any agreement
with respect to its securities that is inconsistent in any material respect with, or superior to, the rights granted to the Holders by this Agreement. 
 5.
Registration Expenses. All Registration Expenses incident to the Parties’ performance of or compliance with their respective obligations under this Agreement or otherwise in connection with any Demand Registration, Requested
Underwritten Offering, Piggyback Registration or Underwritten Piggyback Offering (in each case, excluding any Selling Expenses) shall be borne by the Company, whether or not any Registrable Securities are sold pursuant to a Registration Statement.
“Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with the Trading Market and (B) in
compliance with applicable state securities or “Blue Sky” laws), (ii) printing expenses (including expenses of printing certificates for Company 

  
 15 

 
Securities and of printing Prospectuses if the printing of Prospectuses is reasonably requested by a Holder of Registrable Securities included in the Registration Statement),
(iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel, auditors, accountants and independent petroleum engineers for the Company, (v) Securities Act liability insurance, if the Company so desires
such insurance, (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement, (vii) all expenses relating to marketing the sale of the
Registrable Securities, including expenses related to conducting a “road show” and (viii) the reasonable fees and disbursements of one counsel for the Sponsoring Holders and any local counsel for the Sponsoring Holders to the extent
required. In addition, the Company shall be responsible for all of its expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including expenses payable to third parties and including all salaries
and expenses of their officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on the Trading Market. 

6. Indemnification. 
 (a) The
Company shall indemnify and hold harmless each Holder, its Affiliates and each of their respective officers and directors and any agent thereof (collectively, “Holder Indemnified Persons”), to the fullest extent permitted by
applicable law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines, penalties, interest,
settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Holder Indemnified Person may be involved, or is threatened to be involved,
as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration
Statement under which any Registrable Securities were registered, in any preliminary, final or summary prospectus contained therein (if the Company authorized the use of such preliminary prospectus prior to the Effective Date), or any amendment or
supplement thereto (if used during the period the Company is required to keep the Registration Statement current), or any document incorporated by reference therein, any other such disclosure document (including reports and other documents filed
under the Exchange Act and any document incorporated by reference therein), or in any issuer free writing prospectus, as defined in Rule 433(h) of the Securities Act or in any “road show” as defined by Rule 433(h) of the Securities Act, or
arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they were made,
not misleading; provided, however, that the Company shall not be liable to any Holder Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission
or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or issuer free writing prospectus or road show or such amendment or supplement, in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder Indemnified Person or any underwriter specifically for use in the preparation thereof. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by 

  
 16 

 
this Agreement. This indemnity shall be in addition to any liability the Company may otherwise have and shall remain in full force and effect regardless of any investigation made by or on behalf
of such Holder Indemnified Person or any indemnified party and shall survive the transfer of such securities by such Holder. Notwithstanding anything to the contrary herein, this Section 6 shall survive any termination or
expiration of this Agreement in its entirety or as to any Holder indefinitely. 
 (b) In connection with any Registration Statement in which
a Holder participates, such Holder shall, severally and not jointly, indemnify and hold harmless the Company, its Affiliates and each of their respective officers, directors and any agent thereof, to the fullest extent permitted by applicable law,
from and against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, in any preliminary prospectus (if used prior to the Effective Date
of such Registration Statement), or in any summary or final prospectus or issuer free writing prospectus or road show or in any amendment or supplement thereto (if used during the period the Company is required to keep the Registration Statement
current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which
they were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to the Holder furnished in writing to the Company by such Holder for use therein. This indemnity shall be in
addition to any liability such Holder may otherwise have and shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any indemnified party. In no event shall the liability of any selling Holder
hereunder be greater in amount than the dollar amount of the proceeds received by such Holder from the sale of the Registrable Securities giving rise to such indemnification obligation. 

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks indemnification 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 or there may be
reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party shall 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). An indemnifying
party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with
respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another
indemnified party with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder. 

(d) If the indemnification provided for in this Section 6 is held by a court of competent jurisdiction to be
unavailable to an indemnified party with respect to any Losses referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party 

  
 17 

 
thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other, in connection with the untrue or alleged untrue statement of a material fact or the omission to state a material fact that resulted in
such Losses, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. 

7. Spin-Offs or Split-Offs. If the Company effects the separation of any portion of its business into one or more entities (each, a
“NewCo”), whether existing or newly formed, including, without limitation, by way of spin-off, split-off, carve-out,
demerger, recapitalization, reorganization or similar transaction, and any stockholder will receive equity interests in any such NewCo as part of such separation, the Company shall cause any such NewCo to enter into a registration rights agreement
with such stockholders that provides the Sponsoring Holders with rights vis-á-vis such NewCo that are substantially identical to those set forth in this Agreement. 

8. Facilitation of Sales Pursuant to Rule 144. To the extent it shall be required to do so under the Exchange
Act, the Company shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of
Rule 144), and shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the
limitations of the exemption provided by Rule 144. Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, the Company shall deliver to such Holder a written statement as to whether it has complied
with such requirements. 
 9. Miscellaneous. 

(a) Remedies. In the event of actual or potential breach by the Company of any of its obligations under this Agreement, each
Holder, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company agrees that monetary
damages would not provide adequate compensation for any Losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the event of any action for specific performance in respect of such breach, it
shall waive the defense that a remedy at law would be adequate. 
 (b) Discontinued Disposition. Subject to the last sentence
of Section 3(o), each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e),
such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement

  
 18 

 
as contemplated by Section 3(j) or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has
received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”). The Company may provide
appropriate stop orders to enforce the provisions of this Section 9(b). 
 (c) Amendments and
Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed by the Company and Holders that hold a majority of the Registrable Securities as of the date of such waiver or amendment; provided,
that any waiver or amendment that would have a disproportionate adverse effect on a Holder relative to the other Holders shall require the consent of Holders that hold a majority of the Registrable Securities held by all Holders. The Company shall
provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any
subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right. 

(d) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be
in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via electronic mail as specified in this Section 9(d) prior to
5:00 p.m. Central Time on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via electronic mail as specified in this Agreement later than 5:00 p.m. Central
Time on any date and earlier than 11:59 p.m. Central Time on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service (iv) upon actual receipt by the Party to
whom such notice is required to be given. The address for such notices and communications shall be as follows:

or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (i) the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (ii) such transferee or assignee agrees in
writing to be bound by and subject to the terms set forth in this Agreement. The Company may not assign its rights or obligations hereunder without the prior written consent of the Sponsoring Holders.

obligation of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or electronic mail transmission were the original thereof. 

(h) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in
accordance with, the internal laws of the State of New York. Each of the Parties irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in in the Borough of Manhattan in the City of New York and the United
States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any
such suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any
such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO
REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 

  
 20 

 (i) Cumulative Remedies. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. 
 (j) Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated, and the Parties shall use their reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction.
It is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or
unenforceable. 
 (k) Entire Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the
subject matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and the matters addressed or governed hereby, whether oral or written. 

(l) Termination. Except for Section 6, this Agreement shall terminate as to any Holder, when all
Registrable Securities held by such Holder no longer constitute Registrable Securities. 
 [THIS SPACE LEFT BLANK INTENTIONALLY]

FORM OF 

STOCKHOLDERS’ AGREEMENT 

This STOCKHOLDERS’ AGREEMENT (this “Agreement”), dated as of [●], 2017, is entered into by and
between Tapstone Energy Inc., a Delaware corporation (the “Company”) and GSO E&P Holdings I LP, a Delaware limited partnership (“GSO”). 

WHEREAS, GSO, the Company and certain other parties thereto have entered into that certain Master Reorganization Agreement, dated as of
[●], 2017 (the “Reorganization Agreement”), pursuant to which GSO and the other parties to the Reorganization Agreement agreed to enter into certain restructuring transactions (collectively, the
“Reorganization”) as set forth therein and, in connection therewith, GSO has received shares of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”); and 

WHEREAS, pursuant to the Reorganization Agreement, and in connection with, and effective upon, the completion of an underwritten public
offering (the “IPO”) of shares of Common Stock, GSO and the Company desire to enter into this Agreement to set forth certain understandings between themselves, including with respect to certain corporate governance matters.

 NOW, THEREFORE, in consideration of the mutual covenants contained herein and for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 ARTICLE I 

DEFINITIONS 

Section 1.1 Certain Definitions. As used in this Agreement, the following terms shall have the following meanings: 

“Affiliate” means, with respect to any specified Person, a Person that directly or indirectly Controls or is
Controlled by, or is under common Control with, such specified Person. For purposes of this Agreement, (i) any fund or account managed, advised or sub-advised by or Controlled by GSO or its Affiliates
shall constitute an Affiliate of GSO, and (ii) no party to this Agreement shall be deemed to be an Affiliate of another party to this Agreement solely by reason of the execution and delivery of this Agreement.

understanding, relationship or otherwise, has or shares (a) voting power, which includes the power to vote, or to direct the voting of, such security and/or (b) investment power, which includes the power to dispose of, or to direct the
disposition of, such security. The terms “Beneficially Own” and “Beneficial Ownership” shall have correlative meanings. 

“Board” means the Board of Directors of the Company. 

“Control” (including the terms “Controls,” “Controlled by” and

 ARTICLE II

 GOVERNANCE MATTERS 

Section 2.1 Designees. 

(a) Upon the closing of the IPO, the Board shall consist of seven directors, including Steven C. Dixon, D. Dwight Scott, Robert Horn, David
Posnick, Robert Baker, David Reed and Martha Burger (the “Initial Directors”). Of the Initial Directors, D. Dwight Scott, Robert Horn, David Posnick and Robert Baker are each deemed to be designees of GSO. From and after the
closing of the IPO, the rights of GSO to designate directors to the Board shall be as set forth in the remainder of this Section 2.1. The Company and GSO shall take all Necessary Action to cause the Board to include the
Chief Executive Officer of the Company. 
 (b) The Company shall take all Necessary Action to cause the Board to include a number of
directors designated by GSO (each such director, a “GSO Director”) such that: 
 (i) at least a
majority of the directors on the Board are GSO Directors for so long as GSO and its Affiliates collectively Beneficially Own at least 50% of the outstanding shares of Common Stock; 

(ii) at least 35% of the directors of the Board are GSO Directors for so long as GSO and its Affiliates collectively
Beneficially Own less than 50% but at least 25% of the outstanding shares of Common Stock; and 
 (iii) at least one director
of the Board is a GSO Director for so long as GSO and its Affiliates collectively Beneficially Own less than 25% but at least 5% of the outstanding shares of Common Stock. 

  
 -3- 

 If GSO and its Affiliates collectively Beneficially Own less than 5% of the outstanding shares of
Common Stock, GSO shall not have the right under this Agreement to designate a nominee to the Board. 
 For purposes of calculating the
number of GSO Directors that GSO is entitled to designate pursuant to this Section 2.1(b), any fractional amounts shall automatically be rounded upward to the nearest whole number of GSO Directors that is greater than such fractional amount,
and any such calculations shall be made on a pro forma basis. 
 For the avoidance of doubt, the rights granted to GSO to designate members
of the Board are additive to, and not intended to limit in any way, the rights that GSO or its Affiliates may have to nominate, elect or remove directors under the Company’s certificate of incorporation, bylaws or the General Corporation Law of
the State of Delaware. 
 The Company agrees, to the fullest extent permitted by applicable law (including with respect to any applicable
fiduciary duties under Delaware law), that taking all Necessary Action to effectuate the above shall include (A) including the persons designated pursuant to this Section 2.1(b) in the slate of nominees recommended by the Board for
election or appointment at any meeting of stockholders called for the purpose of electing or appointing directors, (B) nominating and recommending each such individual to be elected or appointed as a director as provided herein and
(C) soliciting proxies or consents in favor thereof. The Company is entitled to identify such individual as a GSO Director pursuant to this Agreement. 

(c) If at any time GSO has designated fewer than the total number of individuals that GSO is then entitled to designate pursuant to Section
2.1(b), GSO shall have the right, at any time and from time to time, to designate such additional individuals that it is entitled to so designate, and if GSO exercises such right, any individuals nominated by or at the direction of the Board or
any duly-authorized committee thereof for election or appointment as directors to fill any vacancy on the Board shall include such designees, and the Company shall use its reasonable best efforts to (i) effect the election or appointment of
such additional designees, whether by increasing the size of the Board or otherwise, and (ii) cause the election or appointment of such additional designees to fill any such newly-created vacancies or to fill any other existing vacancies. 

(d) At any time the members of the Board are allocated among separate classes of directors, (i) the GSO Directors shall be evenly
distributed in different classes of directors to the extent practicable and (ii) after taking into account clause (i) of this Section 2.1(c), GSO shall be permitted to designate the class or classes to which each GSO Director shall
be allocated. 
 (e) GSO shall have the right to remove any GSO Director (with or without cause) appointed by it, from time to time and at
any time, from the Board, exercisable upon written notice to the Company, and the Company shall take all Necessary Action to cause such removal. 

(f) If a vacancy is created on the Board by the death, disability, resignation or removal (whether by GSO or otherwise in accordance with the
Company’s certificate of incorporation and bylaws, as either may be amended or restated from time to time) of a GSO Director, then GSO shall be entitled to designate an individual to fill the vacancy so long as the

  
 -4- 

 
total number of persons that will serve on the Board as designees of GSO immediately following the filling of such vacancy will not exceed the total number of persons GSO is entitled to designate
pursuant to Section 2.1(b) on the date of such replacement designation. The Company shall take all Necessary Action to cause such individual so designated by GSO as such replacement designee to become a member of the Board, as soon as
possible. 
 (g) If at any time the number of GSO Directors exceeds the number of GSO Directors that GSO is then entitled to designate to
the Board, then if requested by the Company, GSO shall take such actions as are reasonably necessary to remove such excess GSO Directors from the Board. 

(h) In addition to any vote or consent of the Board or the stockholders of the Company required by applicable law or the charter or bylaws of
the Company, and notwithstanding anything to the contrary in this Agreement, for so long as this Agreement is in effect and GSO and its Affiliates collectively Beneficially Own at least 25% of the outstanding shares of Common Stock, any action by
the Board to increase or decrease the total number of directors comprising the Board (other than any increase in the total number of directors in connection with the election of one or more directors elected exclusively by the holders of one or more
classes or series of the Company’s stock other than Common Stock) shall require the prior written consent of GSO, delivered in accordance with Section 5.1 of this Agreement. 

Section 2.2 Compensation. Except to the extent GSO may otherwise notify the Company that one or more GSO Directors should receive
a lesser amount, the GSO Directors shall be entitled to compensation consistent with the compensation received by other non-employee directors, including any fees and equity awards, provided that (x) to
the extent any director compensation is payable in the form of equity awards, at the election of a GSO Director, in lieu of any equity award, such compensation shall be paid in an amount of cash equal to the value of the equity award as of the date
of the award, with any such cash subject to the same vesting terms, if any, as the equity awarded to other directors and (y) at the election of a GSO Director, any director compensation (whether cash, equity awards and/or cash in lieu of equity
as may be designated by the electing GSO Director) shall be paid to a stockholder or an Affiliate thereof specified by such GSO Director rather than to such GSO Director. If the Company adopts a policy that directors own a minimum amount of equity
in the Company, GSO Directors shall not be subject to such policy. 
 Section 2.3 Other Rights of GSO Directors. Except as
provided in Section 2.2, each GSO Director serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of
the foregoing, the Company shall indemnify, exculpate, and reimburse fees and expenses of the GSO Directors (including by entering into an indemnification agreement in a form substantially similar to the Company’s form director indemnification
agreement) and provide the GSO Directors with director and officer insurance, in each case, to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the charter and bylaws of the
Company, applicable law or otherwise.
