ARTICLE II. 

REGISTRATION RIGHTS 

Section 2.01 Demand Registration. 

(a) Upon receipt of a written request from a Demand Holder at any time following the 180th day after the date hereof, the Company shall
prepare and file with the Commission a registration statement under the Securities Act (a “Registration Statement”) providing for the resale of the Registrable Securities, which may, at the option of the Demand Holder, be a
registration statement that provides for the resale of the Registrable Securities from time to time pursuant to Rule 415 under the Securities Act (a “Shelf Registration Statement”). Within five (5) business days of the
receipt of a Demand Notice, the Company shall give written notice of such Demand Notice to all Holders, and the Holders shall have three (3) business days following receipt of such notice of the Demand Notice from the Company to request in writing
(including by electronic mail) to the Company to be included as a seller of Registrable Securities in such Registration Statement. The Company shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective
by the Commission as soon as reasonably practicable after the initial filing of the Registration Statement. The Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested
by, the Holders of any and all Registrable Securities covered by such Registration Statement (including those elected to be included in such Registration Statement following notice of a Demand Notice from the Company pursuant to this Section
2.01). The Company 

  
 3 

 
shall use its commercially reasonable efforts to cause the Registration Statement filed pursuant to this Section 2.01 to be continuously effective, supplemented and amended to
the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities (the
“Effectiveness Period”). The Registration Statement when effective (and the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act
and shall not 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 not misleading. As soon as practicable following the date that the Registration
Statement becomes effective, but in any event within two (2) business days of such date, the Company shall provide the Holders with written notice of the effectiveness of the Registration Statement. The Company shall only be obligated to effect
two (2) demand registrations on a Long-Form Registration Statement under this Section 2.01 in any twelve-month period; provided, however, that a registration on a Long-Form Registration Statement
shall not count as a registration under this Section 2.01 unless it has become effective. The Company shall be obligated to effect an unlimited number of registrations under this Section 2.01 on Short-Form Registration
Statements. The Company shall not be obligated to file more than one (1) Registration Statement (including Short-Form Registration Statements) in response to requests pursuant to this Section 2.01 within 90 days after the effective
date of any Registration Statement filed by the Company in response to requests pursuant to this Section 2.01. Once a Holder’s Registrable Securities become eligible for resale without restriction and without the need for current
public information pursuant to any section of Rule 144 (or any similar provision then in effect) under the Securities Act, assuming the Holder of such Registrable Securities is not an affiliate (as defined in Rule 144(a)(1) under the Securities Act)
of the Company, then such Holder may, at its option, at any time, request that the Company take such steps as are reasonably necessary to deregister such Holder’s Registrable Securities. In connection with such request, such Holder’s
rights under this Agreement shall all be terminated, including without limitation the right to demand an Underwritten Offering and the right to participate in a Piggyback Registration, and such Holder, to the extent such Holder beneficially owns
less than 0.5% of the Common Stock then outstanding, shall no longer be subject to any obligations under this Agreement, including without limitation the obligation to enter into letter agreements with underwriters pursuant to
Section 2.13.  
 Section 2.02 Underwritten Offerings. 

(a) Request for an Underwritten Offering. If a Demand Holder(s) elects to dispose of Registrable Securities (whether pursuant to an
effective registration statement or a registration statement requested pursuant to Section 2.01) having a market price, based on the last sales price of the shares of Common Stock as of the trading date prior to the date of demand, of at
least $20.0 million, individually or in aggregate with another Demand Holder (subject to adjustment pursuant to Section 3.04), the Company shall, upon the written request by such Demand Holder, retain underwriters (selected as provided
in Section 2.02(c)) in order to permit such Demand Holder to effect such sale through an Underwritten Offering. Within two (2) business days of the receipt of the Demand Notice, the Company shall give written notice of such Demand
Notice to all Holders, and the Holders shall have three (3) business days following receipt of such notice of the Demand Notice from the Company to request in writing (including by electronic mail) to

  
 4 

 
the Company to include, subject to Section 2.02(e), any Registrable Securities in such Underwritten Offering; provided that, in the case of an already effective shelf
registration statement, unless the Company is eligible to use an Automatic Registration Statement, Holders shall be entitled to include only those Registrable Securities that are available or can be made available for sale pursuant to such
Registration Statement without the need for filing a new registration statement or a post-effective amendment to such Registration Statement. The obligation of the Company to retain underwriters shall include the preparation and entry into an
underwriting agreement, in customary form, with the Managing Underwriter or underwriters, which shall include, among other provisions, such representations, covenants, indemnities and other rights and obligations as are customary and indemnities to
the effect provided in Section 2.08 and taking all reasonable actions as requested by the Managing Underwriter or underwriters to expedite or facilitate the disposition of such Registrable Securities, including causing its management to
participate in a “roadshow” or similar marketing efforts. 
 (b) Block Trades. Notwithstanding the foregoing, if a Demand
Holder wishes to engage in an underwritten block trade off of a Short-Form Registration Statement, then notwithstanding the foregoing time periods, such Holder only need to notify the Company of the block trade offering two business days prior to
the day such offering is to commence (unless a longer period is agreed to by the holders of a majority of the Registrable Securities wishing to engage in the underwritten block trade) and the Company shall promptly notify other holders of
Registrable Securities and such other holders of Registrable Securities must elect whether or not to participate by the next business day (i.e. one business day prior to the day such offering is to commence) (unless a longer period is agreed
to by the holders of a majority of the Registrable Securities wishing to engage in the underwritten block trade) and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such offering (which may close
as early as three business days after the date it commences); provided that the holders of a majority of the Registrable Securities included in such registration shall use commercially reasonable efforts to work with the Company and
the underwriters prior to making such request in order to facilitate preparation of the Registration Statement and other offering documentation related to the underwritten block trade. 

(b) Limitation on Offerings. In no event shall the Company be required hereunder to participate in more than one Underwritten Offering
in any ninety-day period. 
 (c) Selection of Underwriters. The Demand Holder holding a majority of the Registrable Securities
included in any Underwritten Offering requested pursuant to this Section 2.02 shall have the right to select the Managing Underwriter as well as other investment banker(s) and manager(s) to administer the offering, subject to the
Company’s approval, which shall not be unreasonably withheld, conditioned or delayed. 
 (d) Withdrawal. If any Selling Holder
disapproves of the terms of an Underwritten Offering, such Person may elect to withdraw its request that the Company undertake such offering by written notice to the Company; provided, however, that such withdrawal must be made at a
time prior to the time of pricing of such offering. No such withdrawal shall affect the Company’s obligation to pay Registration Expenses, if applicable. 

(e) Priority on Underwritten Offerings Pursuant to a Demand Notice. If in 

  
 5 

 
connection with an Underwritten Offering pursuant to Section 2.02, the Managing Underwriter shall advise the Company that, in its reasonable opinion, the number of securities
requested and otherwise proposed to be included in such Underwritten Offering exceeds the number which can be sold in such offering without an adverse effect on the price, timing or distribution of the securities to be offered (an
“Adverse Effect”), then in the case of any such registration pursuant to Section 2.02, the Company shall include in such Underwritten Offering prior to the inclusion of any securities that are not Registrable
Securities, the number of Registrable Securities that such Managing Underwriter advises the Company can be sold without having such Adverse Effect, pro rata among the Holders that have requested to participate in such Underwritten Offering based on
the relative number of Registrable Securities then held by each such Holder (provided that any securities thereby allocated to a Holder that exceed such Holder’s request shall be reallocated among the remaining requesting Holders in like
manner). 
 Section 2.03 Piggyback Rights. 

(a) Participation. So long as a Holder has Registrable Securities, if the Company proposes to file a Registration Statement or conduct
an Underwritten Offering, whether for its own account or for the account of any holders of its securities (other than in connection with a Demand Notice, which shall be governed by Section 2.01 and Section 2.02), ( a “Piggyback
Registration”), then the Company shall give prompt written notice (a “Piggyback Notice”) (including notice by electronic mail) to each Holder holding at least $0.1 million of the then-outstanding Registrable
Securities of the Company (based on the last sales prices of the shares of Common Stock as of the trading date prior to the date of the Piggyback Notice) regarding such proposed registration, and such notice shall offer such Holders the opportunity
to include in such Piggyback Registration such number of Registrable Securities as each such Holder may request. Each Piggyback Notice shall specify, at a minimum, the number and type of securities proposed to be registered, the proposed date
of filing of such Piggyback Registration with the Commission, the proposed means of distribution, the proposed Managing Underwriter or underwriters (if any and if known) and a good faith estimate by the Company of the proposed minimum offering price
of such securities. Each such Holder shall make such request in writing to the Company (including by electronic mail) within five (5) business days (or one (1) business day in connection with any overnight or bought Underwritten Offering)
after the receipt of any such Piggyback Notice, which request shall specify the number of Registrable Securities intended to be disposed of by such Holder, and, subject to the terms and conditions of this Agreement, the Company shall use its
reasonable best efforts to include in such Piggyback Registration all Registrable Securities held by such Holders; provided, that if, at any time after giving written notice of its intention to register equity securities and prior to the
effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register its equity securities, the Company may, at its election, give written notice of such determination
within five business days thereof to each Holder of Registrable Securities and, thereupon, shall not be obligated to register any Registrable Securities in connection with such registration (but shall nevertheless pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of the Holders of Registrable Securities that a registration be effected under Section 2.01 or Section 2.02. 

  
 6 

 (b) Priority in Connection with Piggyback Registrations. If in connection with an
Underwritten Offering pursuant to this Section 2.03, the Managing Underwriter shall advise the Company that, in its reasonable opinion, the number of securities requested and otherwise proposed to be included in such Underwritten
Offering exceeds the number which can be sold in such offering without an Adverse Effect, then the Company shall include in such registration the number of Registrable Securities that such Managing Underwriter advises the Company can be sold without
having such Adverse Effect. In the case of a primary offering initiated by the Company, such number shall be allocated to (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities of the Holders that
have elected to participate in such Underwritten Offering pro rata among the Holders that have requested to participate in such Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder
(provided that any securities thereby allocated to a Holder that exceed such Holder’s request shall be reallocated among the remaining requesting Holders in like manner), and (iii) third, if any, the number of other securities that,
in the opinion of such Managing Underwriter, can be sold without having such Adverse Effect In connection with a secondary registration on behalf of holders of the Company’s securities (other than the Holders pursuant to Section 2.02),
such number shall be allocated to the securities requested to be sold by the holders initially requesting such registration and the Registrable Securities requested to be included in such registration, pro rata among such persons based on the
relative number of securities then held by each such person (provided that any securities thereby allocated to a person that exceed such person’s request shall be reallocated among the remaining requesting persons in like manner). 

Section 2.04 Selection of Underwriters. If any Piggyback Registration is an Underwritten Offering, the selection of investment
banker(s) and manager(s) for the offering shall be made (a) by the Company, in the event that the Underwritten Offering is conducted by the Company, for its own account or for the account of any holders of its securities (other than in
connection with a Demand Notice), and no single Holder requests to include in the Underwritten Offering more Registrable Securities than the Company or any other holder of its securities, or (b) by the Holder that requests to include in the
Underwritten Offering the most Registrable Securities if there is more than one Holder that requests to include more Registrable Securities than the Company; provided, that, in the case of Section 2.04(b), any such investment
banker(s) and manager(s) must be approved by the Company, with such approval not to be unreasonably withheld, conditioned or delayed. 

Section 2.05 Delay Rights. If the Board determines in its reasonable good faith judgment that the Company’s compliance with
its obligations under this Article II would be materially detrimental to the Company because such registration would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction
involving the Company, (b) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (c) render the Company unable to comply with applicable securities
laws, then the Company shall have the right to postpone compliance with its obligations to all but not less than all Holders under this Article II until such time that, in the Board’s reasonable good faith determination, compliance would
not be materially detrimental to the Company; provided, that such postponement does not exceed 60 calendar days in any twelve-month period.

 Section 2.06 Sale Procedures. In connection with its obligations under this
Article II, the Company will, as expeditiously as possible: 
 (a) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement; 
 (b) if a prospectus
supplement, offering memorandum or similar marketing document will be used in connection with the marketing of an Underwritten Offering and the Managing Underwriter notifies the Company in writing that, in the sole judgment of such Managing
Underwriter, inclusion of detailed information in such prospectus supplement is of material importance to the success of such offering, the Company shall use its commercially reasonable efforts to include such information in such prospectus
supplement, offering memorandum or similar marketing document; 
 (c) furnish to each Selling Holder (i) as far in advance as
reasonably practicable before filing the Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents

the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to
filing the Registration Statement or such other registration statement or supplement or amendment thereto or use of a similar marketing instrument, and (ii) such number of copies of the Registration Statement or such other registration

 (d) if applicable, use its commercially reasonable efforts to
register or qualify the Registrable Securities covered by the Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall

amendment thereto, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus
contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any other
registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable
Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Company agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take
other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing and to take such other reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal

other matters as the underwriters or Selling Holders, as applicable, may reasonably request;

 (i) otherwise use its commercially reasonable efforts to comply with all applicable rules and

holders of Registrable Securities, and the holders of Registrable Securities do not request that their Registrable Securities be included in such Shelf Registration Statement, the Company agrees that, at the request of the holders of a majority of
the Registrable Securities, it shall include in such Automatic Shelf Registration Statement such disclosures as may be required by Rule 430B under the Securities Act in order to ensure that the holders of Registrable Securities may be added to such

 10

respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Registration
Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of
or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not
misleading, and will reimburse each such Selling Holder, its directors, officers, employee and agents, and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such Loss or actions or proceedings as such expenses are incurred; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, its directors, officers, employees and agents or such controlling Person in writing specifically for use in the Registration
Statement or any other registration statement contemplated by this Agreement, or prospectus or any amendment or supplement thereto, as applicable. Such indemnity shall remain in full force and 

  
 12 

 
effect regardless of any investigation made by or on behalf of such Selling Holder or any such directors, officers, employees agents or controlling Person, and shall survive the transfer of such
securities by such Selling Holder. 
 (b) By Each Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold
harmless the Company, its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same
extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration
Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereto; provided,
however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to
such indemnification. 
 (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it
from any liability that it may have to any indemnified party other than under this Section 2.08. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying
party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified
party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel
reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable
defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying
party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other
reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which
such indemnified party is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability
of, the indemnifying party and further, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the

  
 13 

 
consent of such indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified
party. 
 (d) Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government
agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the
statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall the Selling Holder be required to contribute an aggregate amount in excess of the dollar
amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities following an offering giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the
indemnified party on the other shall be determined 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 has been made by, or relates to,
information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party
as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the
subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.08 shall be in addition to any other rights to indemnification
or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 
 Section 2.10
Distributions. If the Holders of Registrable Securities seek to effectuate a distribution in kind of all or part of their respective Registrable Securities to their respective direct or indirect equityholders, the Company shall, subject to
any applicable lock-up agreements, work with the foregoing persons to facilitate such distribution in kind in the manner reasonably requested. 

Section 2.11 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to: 

  
 14 

 (a) make and keep public information regarding the Company available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof; 
 (b) file with the Commission in
a timely manner all reports and other documents required of the Company under the Exchange Act at all times from and after the date hereof; and 

(c) so long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without
registration. 
 Section 2.12 Transfer or Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities granted to a Holder by the Company under this Article II and all other rights as a Holder hereunder (including rights as a Demand Holder) may be transferred or assigned by such Holder to one or more transferee(s) or
assignee(s) of such Registrable Securities; provided, however, that (a) unless such transferee or assignee is an Affiliate of the Holder, each such transferee or assignee holds Registrable Securities representing at least $2.0 million of
Registrable Securities (based on the last sales price of the shares of Common Stock as of the trading date prior to the time of such transfer or assignment), subject to adjustment pursuant to Section 3.04, (b) the Company is given
written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the Registrable Securities with respect to which such registration rights are being transferred or assigned and
(c) each such transferee or assignee agrees to be bound by this Agreement. 
 In the event any Demand Holder elects to transfer or
assigns its rights hereunder as a Demand Holder to a transferee or assignee of all or a portion of its Registrable Securities, such Demand Holder’s Registrable Securities and the Registrable Securities so transferred or assigned shall be
aggregated for purposes of exercising the rights of any Demand Holder hereunder and any rights exercisable by Clearlake or Keystone as a Demand Holder hereunder will thereafter be exercisable by the holder of a majority of the Registrable Securities
held by Clearlake and its assignees or transferees in aggregate or by the holder of a majority of the Registrable Securities held by Keystone and its assignees or transferees in aggregate, as applicable. 

Section 2.13 Limitation on Subsequent Registration Rights. From and after the date hereof, the Company shall not enter into any
agreement with any current or future holder of any securities of the Company that would allow such current or future holder to require the Company to include securities in any registration statement filed by the Company on a basis that would reduce
or limit the rights of the Holders of Registrable Securities hereunder or otherwise on terms more favorable to such other holders than this Agreement. 

Section 2.14 Holdback Agreements. (i) Each Holder of Registrable Securities agrees to enter into a customary letter agreement
with underwriters providing such Holder will not effect 

  
 15 

 
any sale, transfer or distribution of the Registrable Securities during a period, in the case of the Company’s initial Public Offering, commencing on the earlier of the date on which
the Company gives notice to the holders of Registrable Securities that a preliminary prospectus has been circulated for such initial Public Offering or the “pricing” of such offering and continuing to the date that is 180 days following
the date of the final prospectus for such initial Public Offering and, in the case of any other offering, commencing on the earlier of the date on which the Company gives notice to the holders of Registrable Securities of the circulation of a
preliminary or final prospectus for such Public Offering or the “pricing” of such offering and continuing to the date that is 90 days following the date of the final prospectus for such Public Offering (or, in each case, such shorter
period as agreed to by the managing underwriter for such Underwritten Offering), provided that the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally
imposed by the underwriters on the Company or the officers, directors or any stockholder of the Company on whom a restriction is imposed (the foregoing periods, “the Hold-Back Period”). 

(ii) The Company (i) shall not file any registration statement for a Public Offering or cause any such registration statement to become
effective, or effect any public sale or distribution of its equity securities, or any securities, options or rights convertible into or exchangeable or exercisable for such securities during any Holdback Period, (ii) (A) shall use its best
efforts to cause each holder of at least one percent (1%) (on a fully-diluted basis) of its Common Stock, or any securities convertible into or exchangeable or exercisable for Common Stock, purchased from the Company at any time after the date
of this Agreement (other than in a Public Offering) to agree not to effect any of the foregoing transaction during any Holdback Period and (B) shall cause each of its directors and executive officers to agree not to effect any such transactions
during any Holdback Period, in each case, except as part of such underwritten registration, if otherwise permitted, unless the underwriters managing the Public Offering otherwise agree in writing.

be binding upon the successors and assigns of each of the parties, including subsequent Holders of Registrable Securities to the extent permitted herein.

transferred or assigned by the Holders in accordance with Section 2.11 hereof. 
 Section 3.04 Recapitalization,
Exchanges, Etc. Affecting the Registrable Securities. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all securities of the Company or any successor or assign of the Company (whether by

distributions and the like occurring after the date of this Agreement. 
 Section 3.05 Specific Performance. Damages in the
event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each party, in addition to and without limiting any other remedy or right it may have, will have the right to an
injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the
ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity that such
party may have. 
 Section 3.06 Counterparts. This Agreement may be executed in any number of counterparts and by different
parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

jurisdiction. 
 Section 3.10 Scope of Agreement. This Agreement is intended by the parties as a final expression of their
agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than
those set forth 

  
 18 

 
or referred to herein with respect to the rights granted by the Company set forth herein. This Agreement supersedes all prior agreements and understandings between the parties with respect to
such subject matter. 
 Section 3.11 Amendment. (i) This Agreement may be amended only by means of a written amendment
signed by the Company and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that that no such amendment, modification or waiver that would adversely affect a Holder disproportionately to all other
Holders, other than amendments and modifications required to implement the provisions of clause (ii) below, shall be effective against such Holder without the consent of the Holder adversely affected thereby. 

(ii) Subject to the prior written consent of the holders of a majority of the Registrable Securities, the Company may permit any Person who
acquires Common Stock or rights to acquire Common Stock from the Company after the date of this Agreement (the “Acquired Common”) to become a party to this Agreement and to succeed to all of the rights and obligations of a holder of
Registrable Securities under this Agreement, if applicable, by obtaining an executed joinder to this Agreement from such Person in the form of Exhibit A attached hereto (a “Joinder”). Upon the execution and delivery of a Joinder by such
Person, the Acquired Common Stock shall constitute Registrable Securities and such Person shall be a holder of Registrable Securities under this Agreement with respect to the Acquired Common, and the Company shall add such Person’s name and

held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

Person other than the Company and the Holders shall have any obligation hereunder and that, notwithstanding that one or more of the Holders may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any
documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Holders
or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding,
or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general
or limited partner, manager, member, stockholder or Affiliate of any of the Holders or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing,

creation, except in each case for any assignee of the Holders hereunder. 
 Section 3.15 Independent Nature of Each Holder’s
Obligations. The obligations of each Holder under this Agreement are several and not joint with the obligations of any other Holder, and no Holder shall be responsible in any way for the performance of the obligations of any other Holder under
this Agreement. Nothing contained herein, and no action taken by any Holder pursuant thereto, shall be deemed to constitute the Holders as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption
that the Holders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Holder shall be entitled to independently protect and enforce its rights, including without
limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose.

instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.”
Whenever any determination, consent or approval is to be made or given by the Holders under this Agreement, such action shall be in the Holders’ sole discretion unless otherwise specified.

of September 13, 2011 (the “Existing Stockholders Agreement”) among the Company and certain of the parties hereto. The parties hereto that are party to the Existing Stockholders Agreement and the Company acknowledge and
agree that the Existing Stockholders Agreement shall automatically terminate and be of no further force and effect without any action of any party hereto upon the consummation of the Company’s initial Public Offering; provided that such
termination shall not impair the Investors’ (as defined in the Existing Stockholders Agreement) rights to reimbursement pursuant to Section 7.13 of the Existing Stockholders Agreement with respect to any costs or expenses incurred by them
prior to such termination, including those incurred in connection with Company’s initial Public Offering.

SMART SAND, INC. 

[●], 2016 

 SMART SAND, INC. 

STOCKHOLDERS AGREEMENT 

THIS STOCKHOLDERS AGREEMENT (this “Agreement”) is made and entered into as of [●], 2016, by and among Smart Sand, Inc.,
a Delaware corporation (the “Company”), and each of Clearlake Capital Partners II (Master), L.P., a Delaware limited partnership (“Clearlake”), and Keystone Cranberry, LLC, a Pennsylvania limited liability company
(“Keystone” and Clearlake, each a “Principal Stockholder”). This Agreement shall become effective (the “Effective Date”) upon the closing of the Company’s initial public offering of shares of
its common stock, par value $0.001 per share (the “Common Stock”). 
 WHEREAS, the Company is contemplating making an
initial public offering of shares of its Common Stock; 
 WHEREAS, in connection with the initial public offering, the Company and each of
the Principal Stockholders wish to set forth certain understandings between such Principal Stockholder and the Company, including with respect to certain governance matters; 

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company agrees with each of the Principal Stockholders as follows: 

1.    Certain Definitions. As used in this Agreement, the following terms have the following meanings: 

“Affiliate” means, with respect to any person, any other person controlled by, controlling or under common control with such
person; provided that the Company and its Subsidiaries shall not be deemed to be Affiliates of either of the Principal Stockholders. As used herein, “control” (including, with its correlative meanings, “controlling,”
“controlled by” and “under common control with”) means possession, directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of securities, by contract or otherwise).

 “Beneficially Own” means that a specified person has or shares the right, directly or indirectly, through any contract,
arrangement, understanding, relationship or otherwise, to vote shares of capital stock of the Company. 
 “Board” means the
board of directors of the Company. 
 “Change of Control” means (i) the sale or disposition of all or substantially
all of the assets of the Company and its Subsidiaries on a consolidated basis to any person or group (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended), other than to either of the Principal Stockholder or
their respective Affiliates; or (ii) any transaction or series of related transactions (including, but not limited to, a merger or consolidation) that results in any person or group (within the meaning of Section 13(d)(3) of the Securities
Exchange Act of 1934, as amended), other than either of the Principal Stockholders and their respective Affiliates, acquiring shares of Common Stock or other equity interest of the Company that represent more than 50% of the total voting power of
the Company (or any resulting company after such transaction). 

 “Subsidiary” or “Subsidiaries” of any person means any
corporation, partnership, joint venture or other legal entity of which such person (either alone or through or together with any other person), owns, directly or indirectly, 50% or more of the stock or other equity interests which are generally
entitled to vote for the election of the board of directors or other governing body of such corporation or other legal entity. 

2.    Board Nomination Rights.

(a)    The Company covenants and agrees with Clearlake that, on and after the Effective Date, at every meeting of the
Board, or a committee thereof, for which directors of the Company are appointed by the Board or are nominated to stand for election by stockholders of the Company, Clearlake, together with its Affiliates, shall have the right, but not the
obligation, to appoint or nominate for election to the Board, as applicable, a number of representatives equal to (such persons, the “Clearlake Nominees”): (i) three (3) directors so long as Clearlake (together with its Affiliates)
Beneficially Owns at least thirty percent (30%) of the then outstanding Common Stock; (ii) two (2) directors so long as Clearlake (together with its Affiliates) Beneficially Owns at least twenty percent (20%) of the then outstanding Common Stock;

Feliciano, Colin Leonard and Timothy Pawlenty. 
 (b)    The Company covenants and agrees with Keystone that, on and
after the Effective Date, at every meeting of the Board, or a committee thereof, for which directors of the Company are appointed by the Board or are nominated to stand for election by stockholders of the Company, Keystone, together with its
Affiliates, shall have the right, but not the obligation, to appoint or nominate for election to the Board, as applicable, a number of representatives equal to (such persons, the “Keystone Nominees” and together with the Clearlake
Nominees, the “Nominees”): (i) three (3) directors so long as Keystone (together with its Affiliates) Beneficially Owns at least thirty percent (30%) of the then outstanding Common Stock; (ii) two (2) directors so long as Keystone
(together with its Affiliates) Beneficially Owns at least twenty percent (20%) of the then outstanding Common Stock; and (iii) one (1) director so long as Keystone (together with its Affiliates) Beneficially Owns at least ten percent (10%) of the
