2. Registration. 
 (a)
Demand Registration.

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 on 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 timing and method 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) (A) represent at least [3]% of the total outstanding shares of Common Stock or (B) have an aggregate value of at
least $[50] million based on the VWAP (the “Minimum Amount”) as of the date of the Demand Notice. 

(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 offer and
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, and the 

  
 5 













 
intended timing and method of disposition described in, 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 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, as soon as reasonably practicable after the filing thereof, and remain continuously, effective under the Securities Act until the earlier of (A) 180 days (or three
years if a Shelf Registration Statement is requested) after the Effective Date of such Registration Statement or (B) the date on which all Registrable Securities covered by such Registration Statement have been sold or otherwise disposed of or
such Shares are no longer Registrable Securities (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 Requested Underwritten Offering, (B) more than a total of [four] Demand Registrations for which THRC (or any transferee thereof in accordance with
Section 8(e)) is the Initiating Holder, (C) more than a total of [four] Demand Registrations for which Equify Financial (or any transferee thereof in accordance with Section 8(e)) is the
Initiating Holder, (D) more than a total of [four] Demand Registrations for which Mr. Farris Wilks (or any transferee thereof in accordance with Section 8(e)) is the Initiating Holder, and (E) 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 of disposition thereof specified in the Demand Notice; provided, that a
demand for a Shelf Registration Statement shall not count against the number of allowable Demand Registrations for (B), (C) and (D) of this paragraph. 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. Further, a Demand Registration shall not constitute a Demand Registration of the Initiating Holder for purposes of this Section 2(a)(iii) if, as a result of
Section 2(a)(vi), there is included in the Demand Registration less than the lesser of (x) Registrable Securities of the Initiating Holder having a VWAP measured on the Effective Date of the applicable Registration
Statement of $[50] million and (y) [two-thirds] of the number of Registrable Securities the Initiating Holder set forth in the applicable Demand Notice. 

  
 6 













 (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). 
 (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(d)(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 in such registration 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, to the Company, and (C) third, if there remains availability for
additional securities to be included in such Demand Registration following the allocation provided in clauses (A) and (B) above, to any other holders of Company Securities entitled to participate in such Demand Registration, if applicable,
based on the relative number of Company 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 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, 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 (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 shall amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place. 

  
 7 













 (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 Registrable 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 such 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 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 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 the transferee of such Registrable Securities
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 each other Holder 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 Holder then able to effectuate a Demand Registration pursuant to the terms of
Section 2(a) (or 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 

  
 8 













 
Underwritten Offering have an aggregate value of 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 $25 million based on the VWAP 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 Company shall propose three or
more nationally prominent firms of investment bankers reasonably acceptable to the Initiating Holder to act as the managing underwriter or managing underwriters in connection with such Underwritten Offering from which the Initiating Holder shall
select the managing underwriter or managing underwriters. The Initiating Holder, in connection with any other Holder participating in such Underwritten Offering, shall determine the pricing of the Registrable Securities offered pursuant to any
Requested Underwritten Offering and the applicable underwriting discounts and commissions and determine the timing of any such Requested Underwritten Offering. 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, 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(d)(iii)(A), the Requested Underwritten Offering includes less than the lesser of (i) Registrable Securities of the Initiating Holder having a VWAP measured on the effective date of the
related Registration Statement of $[50] million and (ii) [two-thirds] of the number of Registrable Securities the Initiating Holder set forth in the applicable Underwritten Offering Notice. 

(c) Block Trades. Notwithstanding anything contained in this Section 2, in the event a sale of
Registrable Securities is an underwritten transaction requiring the involvement of the Company but not involving (i) any “road show” or (ii) a lock-up agreement of more than [45]
days to which the Company is a party, and which is commonly known as a “block trade” (a “Block Trade”), (1) the requesting Holder shall (A) give at least [four] Business Days prior notice in writing of
such transaction to (i) the Company and (ii) any holder of Registrable Securities that is a Party and (x) holds more than 5% of the Class A Common Stock if able to be identified through public filings or (y) is identified by
the Company as an Affiliate of the Company and (B) with respect to any Block Trade, identify the potential underwriter in such notice with contact information for such underwriter; and (2) the Company shall cooperate with such requesting
Holder to the extent it is reasonably able and shall not be required to give notice thereof to other Holders or permit their participation therein unless reasonably practicable. Any Block Trade shall be for at least $[5] million in expected
gross proceeds. The Company shall not be required to effectuate more than [three] Block Trades in any 90-day period. For the avoidance of doubt, a Block Trade shall not constitute a Requested
Underwritten Offering. 

  
 9 













 (d) 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 Class A Common Stock (other than a registration statement on Form S-4 or Form S-8 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 within three Business Days after sending the Piggyback
Registration Notice. 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 and delivered 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 as may be filed
by the Company with respect to offerings of Class A 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, except if the Underwritten Offering will be made pursuant to a
Shelf Registration Statement, at least two Business Days, before) the commencement of such Underwritten 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 Class A Common Stock that are proposed to be registered (the “Underwritten Offering Piggyback
Notice”). Receipt of any Underwritten Offering Piggyback Notice required to be provided in this Section 2(d)(ii) to Holders shall be kept confidential by the Holder until such proposed Underwritten Offering is
(A) publicly announced or (B) such Holder receives notice that such proposed Underwritten Offering has been abandoned, which such notice shall be provided as reasonably practicable by the Company to each Holder. The Underwritten Offering
Piggyback Notice shall offer Holders the opportunity to include in such Underwritten Offering (and any related registration of Company 

  
 10 













 
Securities, 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 other than an Automatic Shelf Registration Statement, only Registrable Securities of Holders that are
subject to an effective Shelf Registration Statement may be included in such Underwritten Piggyback Offering, unless the Company is then able to file an Automatic Shelf Registration Statement and, in the reasonable judgment of the Company, the
filing of the Automatic Shelf Registration Statement including Registrable Securities of Holders that are not otherwise included in an effective Shelf Registration Statement would not have any material adverse effect on the price, timing or
distribution of the Class A Common Stock 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 within three Business Days after sending the Underwritten Offering Piggyback Notice. 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. 
 (iii) If the managing underwriter or managing underwriters of an
Underwritten Offering advise the Company and the Holders that, in their reasonable opinion, 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 Class A Common Stock proposed to be included in such Underwritten Offering) exceeds the number of shares of Class A Common Stock that can be included without being likely to have a significant adverse effect
on the price, timing or distribution of the Company Securities offered or the market for the Company Securities offered, the Company shall include in such Underwritten Offering (and any related registration, if applicable) only that number of shares
of Class A 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 significant
adverse effect, with such number of shares of Class A Common Stock to be allocated as follows: (A) in the case of a Requested Underwritten Offering, (1) first, pro-rata among all Holders
(including 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, (2) second, if there remains
availability for additional shares of Class A Common Stock to be included in such Underwritten Offering, to the Company, and (3) third, if there remains availability for additional shares of Class A Common Stock to be included in such
Underwritten Offering, to any other holders of Class A Common Stock entitled to participate in such Underwritten Offering, if applicable, based on the relative number of shares of Class A 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 Class A Common Stock to be included in such Underwritten Offering, pro-rata among all Holders desiring to include Registrable 

  
 11 













 
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 Class A Common Stock to be included in such registration, pro-rata among any other holders of Class A Common Stock entitled to participate in such Underwritten Offering, if applicable,
based on the relative number of Class A 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 Underwritten Offering. Any Registrable Securities withdrawn from such Underwritten Offering shall be excluded and withdrawn from the registration, 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. 

(iv) The Company shall have the right to terminate or withdraw any registration initiated by it under this
Section 2(d) 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 5. 
 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: 

(a) In connection with a Demand Registration, the Company will, at least three Business Days prior to the anticipated filing of the
Registration Statement and any related Prospectus or any amendment or supplement thereto (other than, after effectiveness of the Registration Statement, any filing made under the Exchange Act that is incorporated by reference into the Registration
Statement) (for purposes of this subsection, supplements and amendments shall not be deemed to include any filing that the Company is required to make pursuant to the Exchange Act or any amendments and supplements that do not materially alter the
previous disclosure or do nothing more than name Holders and provide information with respect thereto), (i) furnish to such Holders and representatives of such Holders copies of all such documents prior to filing and (ii) provide each Holder
and its representatives the opportunity to (A) review and comment on such documents and (B) object to any information pertaining to such Holder and its plan of distribution that is contained therein, and, in either such case, the Company
shall use commercially reasonable efforts to make any changes reasonably requested by the Holders prior to the filing of the Registration Statement. 

(b) In connection with a Piggyback Registration, Underwritten Piggyback Offering or a Requested Underwritten Offering, the Company will, at
least three Business Days prior to the anticipated filing of any initial Registration Statement that identifies the Holders and any related Prospectus or any amendment or supplement thereto (other 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), as applicable, furnish to such Holders 

  
 12 













 
copies of any such 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 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). The Company will also 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 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; (iii) respond to any comments received from the Commission with respect to each Registration Statement 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; and (iv) cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable to the Holders of such Registrable Securities to consummate
the disposition of such Registrable Securities in accordance with their intended method of distribution thereof. 
 (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 Statement and the disposition of all Registrable Securities covered by a 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 when 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 

  
 13 













 
Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence (but not the details) 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 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 ends. 
 (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) as promptly as reasonably practical 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 as promptly as reasonably practical deliver to each Holder, without charge, as many copies of each Prospectus (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 8(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 (or book-entry shares) representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates (or book-entry shares) 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


  
 14 













 
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 that 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. 

(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, subject to the right of a Holder to withdraw such Holder’s Registrable Securities from an
Underwritten Offering in accordance with the terms of this Agreement, (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 severally agrees to enter into and execute an
underwriting agreement in customary form and sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangement approved by the Persons entitled to select the managing underwriter hereunder and (iii) each
Holder participating in such Underwritten Offering severally agrees to complete and execute all questionnaires, powers of attorney, indemnities, and other documents customarily and reasonably required under the terms of such underwriting
arrangement. Any such underwriting agreement to be entered into among the Company, managing underwriter of such offering and each Holder participating in such Underwritten Offering shall contain representations and warranties by such Holders and
such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions on the part of selling stockholders. All of the representations and warranties by, and the other agreements on the part
of, the Company to, and for the benefit of, the underwriter of such offering, included in each such underwriting agreement shall also be made to, and for the benefit of, such Holder participating in such Underwritten Offering, and any or all of the
conditions precedent to the obligations of such underwriter under such underwriting agreement shall be conditions precedent to the obligations of such Holders. No Holder shall be required in any such underwriting agreement to make any
representations or warranties to, or agreements with, the Company or the underwriter other than representations, warranties or agreements regarding such Holder, such Holder’s Registrable Securities, such Holder’s intended method of
distribution and any other representations required by applicable law or reasonably required by the underwriter or the Company. 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 

  
 15 













 
the terms of such underwriting arrangement, including using commercially reasonable efforts to procure customary legal opinions, auditor “comfort” letters and reports of the independent
mining engineers and geologists 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 mining engineer and
geologist. 
 (l) For a reasonable period of time 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 as determined by the Company in its discretion, for inspection during normal business hours by a representative
of the selling Holders, the managing underwriter and any attorneys or accountants retained by such selling Holders or managing underwriter, 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, applicable 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. 

(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”); provided, however, that in no event
shall any Blackout Period together with any Suspension Period exceed an aggregate of 120 days in any 12-month period. In effecting a Blackout Period, the Company shall not disclose any material non-public information that is the basis for such Blackout Period to a Holder without the consent of the Holder. 

  
 16 













 (p) In connection with an Underwritten Offering, the Company shall use commercially
reasonable efforts to provide to each Holder named as a selling stockholder in any Registration Statement a copy of any auditor “comfort” letters, customary legal opinions or reports of the independent mining engineers and geologists of
the Company relating to the oil and gas reserves of the Company, in each case that have been provided to the managing underwriter in connection with the Underwritten Offering, not later than the Business Day prior to the effective date of such
Registration Statement. 
 (q) In connection with any Underwritten Offering made pursuant to a Registration Statement filed pursuant to
Section 2, if requested by the managing underwriter in an Underwritten Offering, each Holder shall execute a customary “lock-up” agreement with the underwriters of such
Underwritten Offering containing a lock-up period equal to the shorter of (i) the shortest number of days that a director of the Company or “executive officer” (as defined under Section 16
of the Exchange Act) of the Company contractually agrees with the underwriters of such Underwritten Offering not to sell any Company Securities following such Underwritten Offering and (ii) [90] days from the date of the execution of the
underwriting agreement with respect to such Underwritten Offering. Notwithstanding the foregoing, any discretionary waiver or termination of this lock-up provision by the Company or the underwriters with
respect to any of the Holders shall apply to the other Holders as well, pro rata based upon the number of shares subject to such obligations. 

(r) Notwithstanding anything to the contrary in this Agreement, any Holder may make a written election (an “Opt-Out Election”) to no longer receive from the Company any Demand Notice, Piggyback Registration Notice or Underwritten Offering Piggyback Notice (each, a “Covered Notice”),
and, following receipt of such Opt-Out Election, the Company shall not be required to, and shall not, deliver any such Covered Notice to such Holder from the date of receipt of such Opt-Out Election and such Holder shall have no right to participate in any Registration Statement or Underwritten Offering as to which such Covered Notices pertain. An Opt-Out
Election shall remain in effect until it has been revoked in writing and received by the Company. A Holder who previously has given the Company an Opt-Out Election may revoke such election at any time in
writing, and there shall be no limit on the ability of a Holder to issue and revoke subsequent Opt-Out Elections. 

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 the rights granted to the Holders by this Agreement. The Company shall not, prior to the termination of this Agreement, grant any registration rights that
are superior to, conflict with, or would otherwise prevent the Company from performing, the rights granted to the Holders hereby. 

  
 17 













 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 or whether or not a Registration Statement is filed or becomes effective. “Registration
Expenses” means all expenses incurred in connection with registrations, filings or qualifications pursuant to Section 2 and Section 3, (i) registration and filing fees (including fees
and expenses (A) with respect to filings required to be made with the Trading Market, (B) in compliance with applicable state securities or “Blue Sky” laws and (C) with respect to filings with FINRA), (ii) printing expenses
(including expenses of printing certificates for Company 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 mining engineers and geologists 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) reasonable fees and expenses of one counsel to the Holders reasonably acceptable to the Company and selected by the Holders that hold a majority of the
Registrable Securities to be included in such filing in connection with the filing or amendment of any Registration Statement or Prospectus hereunder. 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 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 prospectus (if the Company authorized the use of such preliminary prospectus prior to the Effective Date of such Registration Statement), or in any summary or final prospectus or free writing prospectus (if such free writing prospectus
was authorized for use by the Company) 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; 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 

  
 18 













 
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 free writing prospectus 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, in its capacity as such, 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 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 indefinitely. 

(b) In connection with any Registration Statement in which a Holder participates, such Holder, solely in its capacity as such, 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 free writing prospectus 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, solely in its capacity as such, expressly for use therein; provided, however, that this
Section 6(b) shall not apply to any information furnished in writing by such Holder to the Company that corrected or made not misleading information previously furnished to the Company, if such information was furnished
prior to the filing of any such Registration Statement, preliminary prospectus, summary or final prospectus, or free writing prospectus, or in any amendment or supplement thereto, and the Company failed to include such information 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 net 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 (each, an “Indemnified Party”) 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 Party and indemnifying party 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 

  
 19 













 
not be subject to any liability for any settlement made by the Indemnified Party without its consent (but such consent may not be unreasonably withheld, delayed or conditioned). 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 as provided in clause (i) above 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 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 hand, in connection with the
untrue or alleged untrue statement of a material fact or the omission or alleged 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 or alleged 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 alleged statement or omission or alleged 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. Facilitation of Sales Pursuant to Rule 144. To the extent is 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 such 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. 

8. 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 applicable 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. 

  
 20 













 (b) Discontinued Disposition. 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) (provided that the Company shall not disclose any material non-public
information that is the basis for such notice to the Holder without the consent of the Holder), such Holder will forthwith discontinue disposition of such Registrable Securities under the applicable Registration Statement until such Holder’s
receipt of the copies of the supplemental Prospectus or amended Registration Statement 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 8(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 such Holder. 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 facsimile or electronic mail as specified in this
Section 8(d) prior to 5:00 p.m. in the time zone of the receiving party on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic
mail as specified in this Agreement later than 5:00 p.m. in the time zone of the receiving party on any date and earlier than 11:59 p.m. in the time zone of the receiving party on such date, (iii) the Business Day following the date of mailing,
if sent by nationally recognized overnight courier service or (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:

portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend 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, that (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 Holders. 

(f) No Third Party Beneficiaries. Nothing in this Agreement, whether express or implied, shall be construed to give any Person, other
than the Parties or their respective successors and permitted assigns and any Indemnified Party, any legal or equitable right, remedy, claim or benefit under or in respect of this Agreement. 

(g) Execution and Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile or electronic mail transmission, such signature shall create a valid binding 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 LAWS OF THE STATE OF [DELAWARE] (WITHOUT GIVING EFFECT TO CONFLICT OF LAW RULES OR PROVISIONS (WHETHER OF THE STATE OF [DELAWARE] OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION
OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF [DELAWARE]). With respect to any Proceeding arising out of or relating to this Agreement, each of the Parties hereby irrevocably (a) submits to the exclusive jurisdiction of the [Court of
Chancery of the State of Delaware] and the [United States District Court for the District of Delaware] and the appellate courts therefrom (the “Selected Courts”) and waives any objection to venue being laid in the Selected
Courts whether based on the grounds of forum non conveniens or otherwise and hereby agrees not to commence any such Proceeding other than before one of the Selected Courts; provided, however, that a Party may commence any Proceeding in
a court other than a Selected Court solely for the purpose of enforcing an order or judgment issued by one of the Selected Courts; (b) consents to service of process in any Proceeding by the mailing of copies thereof by registered or certified
