any portion of their Registrable Securities on Form S-3 or any similar short-form registration 

  
 4 

 
(“Short-Form Registrations”) if available. All registrations requested pursuant to this Section 2(a) are referred to herein as “Demand
Registrations.” The Holder making a Demand Registration may request that the registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and, if the Company is a WKSI at the time
any request for a Demand Registration is submitted to the Company, that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration
Statement”). Except to the extent that Section 2(c) applies, promptly upon receipt of a request for a Demand Registration (but in no event more than five Business Days thereafter), the Company shall give written notice of
the Demand Registration to all other Holders. Notwithstanding the foregoing, other than delivery to each Holder of the written notice in accordance with this Section 2(a), the Company shall not be required to take any action that would
otherwise be required under this Section 2 if such action would violate Section 4(a) hereof or any similar provision contained in the underwriting agreement entered into in connection with any underwritten Public Offering.

 (b) Demand Registrations. Each Holder shall be entitled to request an unlimited number of Demand Registrations in which the
Company shall pay all Registration Expenses, regardless of whether any registration statement is filed or any such Demand Registration is consummated. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use
any applicable short form and the managing underwriters (if any) agree to the use of a Short-Form Registration. After the Company has become subject to the reporting requirements of the Exchange Act, the Company shall use its reasonable best efforts
to make Short-Form Registrations available for the sale of Registrable Securities. All Long-Form Registrations shall be underwritten registrations unless otherwise approved by the applicable Holder. 

(c) Shelf Registrations. 

(i) Subject to the availability of required financial information, as promptly as practicable after the Company receives
written notice of a request for a Shelf Registration from a Holder (a “Shelf Registration Request”) and the expiration of the Shelf Registration Participation Deadline (as defined below), the Company shall file with the
Securities and Exchange Commission a registration statement under the Securities Act for the Shelf Registration (a “Shelf Registration Statement”). As promptly as practicable, but no later than two Business Days after receipt
of a Shelf Registration Request, the Company shall give written notice (the “Shelf Registration Notice”) of such Shelf Registration Request to all other Holders. The Company, subject to Section 8 hereof, shall
include in such Shelf Registration (and in all related registrations and qualifications under state blue sky laws) all Registrable Securities of each Holder with respect to which the Company has received a written request for inclusion therein
within two Business Days after the Shelf Registration Notice was delivered (such deadline, the “Shelf Registration Participation Deadline”). The Company shall use its reasonable best efforts to cause any Shelf Registration
Statement filed in accordance with this Section 2(c)(i) to be declared effective under the Securities Act as soon as practicable after the initial filing of such Shelf Registration Statement and, once effective, the Company shall cause
such Shelf Registration Statement to remain continuously effective for such time period as is specified in the request by the Holders, but for no time period 

  
 5 

 
longer than the period ending on the earliest of (A) the date on which all Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement and (B) the date as of which there are no longer any Registrable Securities covered by such Shelf Registration Statement in existence. 

(ii) Notwithstanding the rights of each Holder under Section 2(c)(i), subject to the availability of required
financial information, as promptly as practicable after the Company becomes eligible to file a Shelf Registration Statement on Form S-3 the Company shall file with the Securities and Exchange Commission a Shelf Registration Statement on Form S-3
that includes in such Shelf Registration Statement (and in all related registrations and qualifications under state blue sky laws) all Registrable Securities held by each Holder. No later than five Business Days prior to the initial filing of the
Shelf Registration Statement pursuant to this Section 2(c)(ii), the Company shall give written notice of such filing to each Holder (the “Shelf Registration Filing Notice”). Within two Business Days after the
receipt of the Shelf Registration Filing Notice each holder shall send the Company a written notice specifying the number of Registrable Securities then held by each Holder or, at the option of such Holder, a lesser number of Registrable Securities
to be included in such Shelf Registration Statement, as well as any additional information requested by the Company pursuant to Section 5(c). The Company shall use its reasonable best efforts to cause any Shelf Registration Statement
filed in accordance with this Section 2(c)(ii) to be declared effective under the Securities Act as soon as practicable after the initial filing of such Shelf Registration Statement and, once effective, the Company shall cause such Shelf
Registration Statement to remain continuously effective for such time period ending on the earliest of (A) the date on which all Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement and (B) the date as of which there are no longer any Registrable Securities covered by such Shelf Registration Statement in existence. 

(iii) In the event that a Shelf Registration Statement is effective, Holders representing Registrable Securities with a market
value of at least $15 million (or such lesser amount if all Registrable Securities available for sale pursuant to such registration statement held by a Holder are requested to be included) shall have the right at any time or from time to time to
elect to offer and sell (including pursuant to an underwritten offering (an “Underwritten Takedown”)) Registrable Securities available for sale pursuant to such Shelf Registration Statement (“Shelf Registrable
Securities”), so long as the Shelf Registration Statement remains effective, and the Company shall pay all Registration Expenses in connection therewith. The applicable Holders shall make such election by delivering to the Company a
written request (a “Shelf Offering Request”) for such offering specifying the number of Shelf Registrable Securities that such Holders desire to sell pursuant to such offering (the “Shelf Offering”).
As promptly as practicable, but no later than two Business Days after receipt of a Shelf Offering Request, the Company shall give written notice (the “Shelf Offering Notice”) of such Shelf Offering Request to all other
holders of Shelf Registrable Securities. The Company shall, as expeditiously as possible (and in any event within 10 days after the receipt of a Shelf Offering Request, unless a longer period is agreed to by the Holders of the Registrable Securities
that made the Shelf Offering Request), use its reasonable best efforts to facilitate such Shelf Offering. 

  
 6 

 (iv) The Company shall, at the request of any Holder of the Registrable
Securities covered by a Shelf Registration Statement, file any prospectus supplement or, if the applicable Shelf Registration Statement is an Automatic Shelf Registration Statement, any post-effective amendments and otherwise take any action
necessary to include therein all disclosure and language deemed necessary or advisable by such Holders to effect such Shelf Offering. 
 (d)
Restrictions on Demand Registration and Shelf Offerings. 
 (i) Notwithstanding the foregoing, the Company shall not
be obligated to effect any Demand Registration within 45 days after the consummation of another Demand Registration. Further notwithstanding the foregoing, the Company may postpone, for up to 90 days from the date of the request, the filing or the
effectiveness of a registration statement for a Demand Registration or suspend the filing of a Shelf Registration Statement or the use of a prospectus that is part of a Shelf Registration Statement for up to 90 days from the date of the Suspension
Notice (as defined below) and therefore suspend sales of the Shelf Registrable Securities (such period, the “Suspension Period”) by providing written notice to the Holders if (A) the Company’s board of directors
determines in its reasonable good faith judgment that the offer or sale of Registrable Securities would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material
acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer, recapitalization, reorganization or other transaction involving the Company or any Subsidiary, or (B) upon
advice of counsel, the sale of Registrable Securities pursuant to the registration statement would require disclosure of MNPI not otherwise required to be disclosed under applicable law, and either (x) the Company has a bona fide business
purpose for preserving the confidentiality of such transaction or (y) disclosure of such MNPI would have a material adverse effect on the Company or the Company’s ability to consummate such transaction; provided that in such event,
the Holders shall be entitled to withdraw such request for a Demand Registration or underwritten Shelf Offering and the Company shall pay all Registration Expenses in connection with such Demand Registration or Shelf Offering. The Company may delay
a Demand Registration hereunder only once in any twelve-month period, except with the consent of the applicable Holder. 

(ii) In the case of an event that causes the Company to suspend the filing or use of a Shelf Registration Statement as set
forth in paragraph (d)(i) above or pursuant to applicable subsections of Section 5(a)(vi) (a “Suspension Event”), the Company shall give a notice to the Holders of Registrable Securities registered pursuant to
such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice shall state generally the basis for the notice and that such suspension shall continue only for so long
as the Suspension Event or its effect is continuing. If the basis of such suspension is nondisclosure of MNPI, the Company shall not be required to disclose the subject matter of such MNPI to Holders. A Holder shall

  
 7 

 
not effect any sales of the Registrable Securities pursuant to such Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior
to receipt of an End of Suspension Notice (as defined below). Holders may recommence effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following written notice to such effect (an
“End of Suspension Notice”) from the Company, which End of Suspension Notice shall be given by the Company to the Holders promptly following the conclusion of any Suspension Event. 

(iii) Notwithstanding any provision herein to the contrary, if the Company gives a Suspension Notice with respect to any Shelf
Registration Statement pursuant to this Section 2(d), the Company agrees that it shall provide copies of any supplemented or amended prospectus necessary to resume sales, with respect to each Suspension Event. 

(e) Selection of Underwriters. The Holder requesting the Demand Registration or Underwritten Takedown shall have the right to select
the investment banker(s) and manager(s) to administer such offering (including assignment of titles), subject to the Company’s approval not be unreasonably withheld, conditioned or delayed. 

(f) Other Registration Rights. The Company represents and warrants that it is not a party to, or otherwise subject to, any other
agreement granting registration rights to any other Person with respect to any securities of the Company. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company or any Subsidiary to register
any Capital Stock of the Company or of any Subsidiary, or any securities convertible or exchangeable into or exercisable for such securities. 

Section 3. Piggyback Registrations. 

(a) Right to Piggyback. Following the IPO, whenever the Company proposes to register any of its securities under the Securities Act
(other than (i) pursuant to a Demand Registration, (ii) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange Commission or any successor or similar forms or (iii) a registration on any form
that does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities) and the registration form to be used may be used for the registration of
Registrable Securities (a “Piggyback Registration”), the Company shall give prompt written notice to all Holders of its intention to effect such Piggyback Registration and, subject to the terms of Section 3(c),
shall include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities of each Holder with respect to which the Company has received a written
request for inclusion therein within 5 days after delivery of the Company’s notice. 
 (b) Piggyback Expenses. The Registration
Expenses of the Holders shall be paid by the Company in all Piggyback Registrations, whether or not any such registration became effective. 

  
 8 

 (c) Priority on Registrations. If a Piggyback Registration is an underwritten primary
registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering
without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second,
the Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the Holders on the basis of the number of Registrable Securities then
owned by each such Holder that such Holder of Registrable Securities shall have requested to be included therein, and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be
sold without any such adverse effect. 
 (d) 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 at the election of the Company; provided that Holders representing a majority of the Registrable Securities included in such Piggyback Registration may request
that one or more investment banker(s) or manager(s) be included in such offering (such request not to be binding on the Company or such other initiating holders of Company securities). 

(e) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under
this Section 3 whether or not any Holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 6. 

Section 4. Holdback Agreements. 

(a) Holders of Registrable Securities. If requested by the managing underwriter(s), each Holder participating in an underwritten Public
Offering shall enter into customary lock-up agreements, substantially consistent with the lock-up agreements entered into by such Holders in connection with the IPO, with the managing underwriter(s) of such Public Offering. Each Holder not
participating in an offering pursuant to this Agreement agrees to be bound by the terms of such customary lock-up agreement entered into by the participating Holders in connection therewith as if such Holder had been a party thereto; provided
that, notwithstanding the terms of the customary lock-up agreement entered into by the participating Holders, non-participating Holders shall not be prohibited from (i) establishing any contract, instruction or plan (a “Plan”)
that satisfies all of the requirements of Rule 10b5-1(c)(1) under the Exchange Act during the lock-up period set forth in such agreements (provided that no sales may be made pursuant to such a Plan prior to the expiration of the lock-up
period set forth in such agreements and no public announcement of the establishment or existence of a Plan or filing in respect thereof is required or made voluntarily prior to the expiration of the lock-up period set forth in such agreements) or
(ii) making sales pursuant to a Plan that exists on the date of the customary lock-up agreement entered into by the participating Holders. The Company may impose stop-transfer instructions with respect to the Shares (or other securities)
subject to the restrictions set forth in this Section 4(a) until the end of the lock-up period set forth in such agreements, including any extension thereof as may be required to comply with FINRA Rule 2711(f)(4). 

  
 9 

 (b) Exceptions. The foregoing holdback agreements in Section 4(a) shall not
apply to a registration on Form S-8 or any successor or similar form or otherwise in connection with an employee benefit plan or in connection with any registration on Form S-4 or any successor or similar form in connection with any type of
acquisition transaction or exchange offer. 
 Section 5. Registration Procedures. 

(a) Whenever the Holders have requested that any Registrable Securities be registered pursuant to this Agreement or have initiated a Shelf
Offering, the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously
as possible: 
 (i) in accordance with the Securities Act and all applicable rules and regulations promulgated thereunder,
prepare and file with the Securities and Exchange Commission a registration statement, and all amendments and supplements thereto and related prospectuses with respect to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become effective (provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the Holders copies of all such documents
proposed to be filed, which documents shall be subject to the review and comment of such counsel); 
 (ii) notify each Holder
of (A) the issuance by the Securities and Exchange Commission of any stop order suspending the effectiveness of any registration statement or the initiation of any proceedings for that purpose, (B) the receipt by the Company or its counsel
of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (C) the effectiveness of each
registration statement filed hereunder; 
 (iii) prepare and file with the Securities and Exchange Commission such amendments
and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period ending when all of the securities covered by such registration statement
have been disposed of in accordance with the intended methods of distribution by the sellers thereof set forth in such registration statement (but in any event not before the expiration of any longer period required under the Securities Act or, if
such registration statement relates to an underwritten Public Offering, such longer period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with sale of Registrable Securities by an
underwriter or dealer) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the
sellers thereof set forth in such registration statement; 
 (iv) furnish to each seller of Registrable Securities thereunder
such number of copies of such registration statement, each amendment and supplement thereto, the 

  
 10 

 
prospectus included in such registration statement (including each preliminary prospectus), each Free Writing Prospectus and such other documents as such seller may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by such seller; 
 (v) use reasonable best efforts to register
or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subparagraph or (B) subject itself to taxation in any such jurisdiction); 
 (vi)
notify each seller of such Registrable Securities (A) promptly after it receives notice thereof, of the date and time when such registration statement and each post-effective amendment thereto has become effective or a prospectus or supplement
to any prospectus relating to a registration statement has been filed and when any registration or qualification has become effective under a state securities or blue sky law or any exemption thereunder has been obtained, (B) promptly after
receipt thereof, of any written comments by the Securities and Exchange Commission, or any request by the Securities and Exchange Commission or other federal or state governmental authority for amendments or supplements to such registration
statement or such prospectus, or for additional information (whether before or after the effective date of the registration statement) or any other correspondence with the Securities and Exchange Commission relating to, or which may affect, the
registration and (C) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an
untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, subject to Section 2(d), at the request of any such seller, the Company shall prepare a supplement or amendment to such
prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

 (vii) use reasonable best efforts to cause all such Registrable Securities to be listed on each securities exchange on
which similar securities issued by the Company are then listed and, if not so listed, to be listed on a securities exchange; 

(viii) use reasonable best efforts to provide a transfer agent, registrar and CUSIP number for all such Registrable Securities
not later than the effective date of such registration statement; 
 (ix) enter into and perform such customary agreements
(including underwriting agreements in customary form), which may include indemnification provisions in favor of underwriters and other Persons in addition to the provisions of Section 7 hereof, make such representations and warranties to
the Holders registering 

  
 11 

 
securities and the underwriters or agents, if any, in form, substance and scope as are customarily made by issuers in public offerings similar to the offering then being undertaken, and take all
such other actions as the Holders of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; 

(x) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate and business documents and properties of the Company as shall be
necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors, employees, agents, representatives and independent accountants to make themselves available to discuss the business of the
Company and to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; 

(xi) use reasonable best efforts to ensure that any Free Writing Prospectus utilized in connection with any Demand Registration
or Piggyback Registration hereunder complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the extent required thereby, is retained in accordance with the Securities Act to the extent required
thereby and, when taken together with the related prospectus, shall not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were
made, not misleading; 
 (xii) otherwise use reasonable best efforts to comply with all applicable rules and regulations of
the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company’s first full
calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158; 

(xiii) to the extent that a Holder, in its sole and exclusive judgment, might be deemed to be an underwriter of any Registrable
Securities or a controlling person of the Company, permit such Holder to participate in the preparation of such registration or comparable statement and allow such Holder to provide language for insertion therein, in form and substance satisfactory
to the Company, which in the reasonable judgment of such Holder and its counsel should be included; 
 (xiv) in the event of
the issuance of any stop order suspending the effectiveness of a registration statement, or the issuance of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Common Stock included in such

 (xix) in the case of any underwritten Public Offering, use its reasonable best efforts to obtain

to remain effective; 
 (xxii) if the Company does not pay the filing fee covering the Registrable Securities at the time an
Automatic Shelf Registration Statement is filed, pay such fee at such time or times as the Registrable Securities are to be sold; 

(xxiii) if an Automatic Shelf Registration Statement has been outstanding for at least three (3) years, at the end of the

similar securities issued by the Company are then listed or quotation of the Registrable Securities on any inter-dealer quotation system. Each Person that sells securities pursuant to a Demand Registration or Piggyback Registration hereunder shall
bear and pay all underwriting discounts and commissions applicable to the securities sold for such Person’s account. 
 (b) Counsel
Fees and Disbursements. In connection with each Demand Registration, each Piggyback Registration and each Shelf Offering that is an underwritten Public Offering, the Company shall reimburse the Holders of Registrable Securities included in such
registration for the reasonable fees and disbursements of (i) one counsel chosen by the Holders representing a majority of the Registrable Securities included in such registration or participating in such Shelf Offering, and (ii) each
additional counsel retained by any Holder for the purpose of rendering an opinion on behalf of such Holder in connection with any Demand Registration, Piggyback Registration or Shelf Offering that is an underwritten Public Offering, where the
counsel referred to in clause (i) is unable or unwilling to render an opinion on behalf of such Holder. 
 Section 7.
Indemnification and Contribution. 
 (a) By the Company. The Company shall indemnify and hold harmless, to the extent permitted
by law, each Holder, such Holder’s officers, directors, managers, employees, agents and representatives, and each Person who controls such Holder (within the meaning of the Securities Act) (the “Holder Indemnified
Parties”) against all losses, claims, actions, damages, liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) caused by,
resulting from, arising out of, based upon or related to any of the following statements, omissions or violations (each a “Violation”) by the Company: (i) any untrue or alleged untrue statement of material fact

  
 15 

 
contained in (A) any registration statement, prospectus, preliminary prospectus or Free Writing Prospectus, or any amendment thereof or supplement thereto or (B) any application or
other document or communication (in this Section 7, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in
any jurisdiction in order to qualify any securities covered by such registration under the securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and
relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In addition, the Company will reimburse such Holder Indemnified Party for any legal or any other expenses reasonably
incurred by them in connection with investigating or defending any such losses. Notwithstanding the foregoing, the Company shall not be liable in any such case to the extent that any such losses result from, arise out of, are based upon, or relate
to an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus, preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto, or in any
application, in reliance upon, and in conformity with, written information prepared and furnished in writing to the Company by such Holder Indemnified Party expressly for use therein or by such Holder Indemnified Party’s failure to deliver a
copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Holder Indemnified Party with a sufficient number of copies of the same. In connection with an underwritten offering, the
Company shall indemnify such underwriters, their officers and directors, and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holder
Indemnified Parties. 
 (b) By Each Holder. In connection with any registration statement in which a Holder is participating, each
such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the
Company, its officers, directors, managers, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder; provided that the
obligation to indemnify shall be individual, not joint and several, for each Holder and shall be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement. 

(c) Claim Procedure. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying
party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall impair any Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying
party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between 

  
 16 

 
such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or
delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect
to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicted
indemnified parties shall have a right to retain one separate counsel, chosen by the Holders representing a majority of the Registrable Securities included in the registration if such Holders are indemnified parties, at the expense of the
indemnifying party. 
 (d) Contribution. If the indemnification provided for in this Section 7 is held by a court of
competent jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party shall
contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action 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 statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided that the maximum amount of
liability in respect of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to
such registration. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties
hereto agree that it would not be just or equitable if the contribution pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable
considerations. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending against any action or claim which is the subject hereof. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(t) of the Securities Act) shall be entitled to
contribution from any Person who is not guilty of such fraudulent misrepresentation. 
 (e) Release. No indemnifying party shall,
except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release
from all liability in respect to such claim or litigation. Notwithstanding anything to the contrary in this Section 7, an indemnifying party shall not be liable for any amounts paid in settlement of any loss, claim, damage, liability or
action if such settlement is effected without the consent of the indemnifying party, such consent not to be unreasonably withheld, conditioned or delayed. 

  
 17 

 (f) Non-exclusive Remedy; Survival. The indemnification and contribution provided for
under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this Agreement. Notwithstanding the foregoing, to
the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the IPO are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall
control. 
 Section 8. Underwritten Registrations. 

(a) Participation. No Person may participate in any Public Offering hereunder which is underwritten unless such Person (i) agrees
to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to any over-allotment or
“green shoe” option requested by the underwriters; provided that no Holder shall be required to sell more than the number of Registrable Securities such Holder has requested to include) and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements and that are consistent in all material respects with the documents to be completed and executed
by the Holders. Each Holder shall execute and deliver such other agreements as may be reasonably requested by the Company and the lead managing underwriter(s) that are consistent with such Holder’s obligations under Section 4,
Section 5 and this Section 8(a) or that are necessary to give further effect thereto and that are consistent in all material respects with the documents to be completed and executed by the Holders. To the extent that any such
agreement is entered into pursuant to, and consistent with, Section 4 and this Section 8(a), the respective rights and obligations created under such agreement shall supersede the respective rights and obligations of the
Holders, the Company and the underwriters created pursuant to this Section 8(a). 
 (b) Price and Underwriting Discounts.
In the case of an underwritten Demand Registration or Underwritten Takedown requested by a Holder pursuant to this Agreement, the price, underwriting discount and other financial terms of the related underwriting agreement for the Registrable
Securities shall be determined by such Holder. 
 (c) Suspended Distributions. Each Person that is participating in any registration
under this Agreement, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5(a)(vi)(B) or (C), shall immediately discontinue the disposition of its Registrable Securities
pursuant to the registration statement until such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by Section 5(a)(vi). 

  
 18 

 Section 9. Additional Parties; Joinder. Subject to the prior written consent of each
Holder, the Company may make any Person who acquires Common Stock or rights to acquire Common Stock from the Company after the date hereof a party to this Agreement (each such Person, an “Additional Investor”) and to succeed
to all of the rights and obligations of a Holder under this Agreement by obtaining an executed joinder to this Agreement from such Additional Investor in the form of Exhibit A attached hereto (a “Joinder”). Upon the execution
and delivery of a Joinder by such Additional Investor, the Common Stock of the Company acquired by such Additional Investor or to which such Additional Investor has the right to acquire (the “Acquired Common”) shall be
Registrable Securities to the extent provided herein, such Additional Investor shall be a Holder under this Agreement with respect to the Acquired Common, and the Company shall add such Additional Investor’s name and address to the Schedule of
Investors and circulate such information to the parties to this Agreement. 
 Section 10. Current Public Information. At all
times after the Company has filed a registration statement with the Securities and Exchange Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file all reports required to be filed by it under
the Securities Act and the Exchange Act and shall take such further action as any Holder may reasonably request, all to the extent required to enable such Holders to sell Registrable Securities pursuant to Rule 144. Upon request, the Company shall
deliver to any Holder a written statement as to whether it has complied with such requirements. 
 Section 11. Subsidiary Public
Offering. If, after an initial Public Offering of the Capital Stock of one of its Subsidiaries (including the Company), the Company distributes securities of such Subsidiary to its equityholders, then the rights and obligations of the Company
pursuant to this Agreement shall apply, mutatis mutandis, to such Subsidiary, and the Company shall cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement. 

Section 12. MNPI Provisions. 

(a) Each Holder acknowledges that (i) the provisions of this Agreement that require communications by the Company or other Holders to such
Holder may result in such Holder and its Representatives (as defined below) acquiring MNPI (which may include, solely by way of illustration, the fact that an offering of the Company’s securities is pending or the number of Company securities
or the identity of the selling Holders), and (ii) there is no limitation on the duration of time that such Holder and its Representatives may be in possession of MNPI and no requirement that the Company or other Holders make any public
disclosure to cause such information to cease to be MNPI; provided that the Company will use reasonable best efforts to promptly notify each Holder if any proposed registration or offering for which a notice has been delivered pursuant to
this Agreement has been terminated or aborted. 
 (b) Each Holder agrees that it will maintain the confidentiality of such MNPI and, to the
extent such Holder is not a natural person, such confidential treatment shall be in accordance with procedures adopted by it in good faith to protect confidential information of third parties delivered to such Holder
(“Policies”); provided that a Holder may deliver or disclose MNPI to (i) its directors, officers, employees, agents, attorneys, affiliates and financial and other advisors (collectively, the
“Representatives”), but solely to the extent such disclosure reasonably relates to its evaluation of exercise of its rights under this Agreement and the sale of any Registrable

  
 19 

 
Securities in connection with the subject of the notice, (ii) any federal or state regulatory authority having jurisdiction over such Holder, (iii) any Person if necessary to effect
compliance with any law, rule, regulation or order applicable to such Holder, (iv) in response to any subpoena or other legal process, or (v) in connection with any litigation to which such Holder is a party; provided further, that
in the case of clause (i), the recipients of such MNPI are subject to the Policies or agree to hold confidential the MNPI in a manner substantially consistent with the terms of this Section 12 and that in the case of clauses
(ii) through (v), such disclosure is required by law and you promptly notify the Company of such disclosure to the extent such Holder is legally permitted to give such notice. 

(c) Each Holder, by its execution of a counterpart to this Agreement or of a Joinder, hereby (i) acknowledges that it is aware that the
U.S. securities laws prohibit any Person who has MNPI about a company from purchasing or selling, directly or indirectly, securities of such company (including entering into hedge transactions involving such securities), or from communicating such
information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities, and (ii) agrees that it will not use or permit any third party to use, and that it will
use its reasonable best efforts to assure that none of its Representatives will use or permit any third party to use, any MNPI the Company provides in contravention of the U.S. securities laws and it will cease trading in the Company’s
securities while in possession of MNPI. 
 (d) Each Holder shall have the right, at any time and from time to time (including after
receiving information regarding any potential Public Offering), to elect not to receive any notice that the Company or any other Holders otherwise are required to deliver pursuant to this Agreement by delivering to the Company a written statement
signed by such Holder that it does not want to receive any notices hereunder (an “Opt-Out Request”); in which case and notwithstanding anything to the contrary in this Agreement the Company and other Holders shall not be
required to, and shall not, deliver any notice or other information required to be provided to Holders hereunder to the extent that the Company or such other Holders reasonably expect would result in a Holder acquiring MNPI. An Opt-Out Request may
state a date on which it expires or, if no such date is specified, shall remain in effect indefinitely. A Holder who previously has given the Company an Opt-Out Request may revoke such request at any time, and there shall be no limit on the ability
of a Holder to issue and revoke subsequent Opt-Out Requests. 
 Section 13. General Provisions. 

(a) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived
only with the prior written consent of the Company and each Holder; provided that no such amendment, modification or waiver that would adversely affect a Holder in a manner that is different from any other Holder (provided that the
accession by any Additional Investor to this Agreement pursuant to Section 9 shall not be deemed to adversely affect any Holder), shall be effective against such Holder without the prior written consent of such Holder. The failure or
delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in
accordance with its terms. A waiver or consent to or of any breach or default by 

  
 20 

 
any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the
performance by that Person of the same or any other obligations of that Person under this Agreement. 
 (b) Remedies. The parties to
this Agreement shall be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other
rights existing in their favor. The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and
remedies existing hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent
violation of the provisions of this Agreement. 
 (c) Severability. Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any
jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall
be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein. 

(d) Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any
way. 
 (e) Successors and Assigns. This Agreement shall bind and inure to the benefit and be enforceable by the Company and its
successors and assigns and the Holders and their respective successors and assigns (whether so expressed or not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit Holders
are also for the benefit of, and enforceable by, any subsequent or successor Holder. 
 (f) Notices. Any notice, demand or other
communication to be given under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or delivered (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic
mail or facsimile if sent during normal business hours of the recipient but, if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or
(iv) three Business Days after it is mailed to the recipient by first class mail, return receipt requested. Such notices, demands and other communications shall be sent to the Company and the Holders at the addresses specified below and to any
other party subject to this Agreement at such address or to the attention of such other Person as the recipient party has specified by prior written notice to the sending party. Any party may change such party’s address for receipt of notice by

(c) Benefits. During the Term, the Executive shall be eligible to participate in employee benefit plans, programs and arrangements of
the Company in accordance with their terms, as in effect from time to time, and as are generally provided by the Company to its executive officers.

the Executive, as applicable, without any breach of this Agreement only under the following circumstances: 
 (a) Circumstances. 

(i) Death. The Executive’s employment hereunder shall terminate upon the Executive’s death. 

(ii) Disability. If the Executive incurs a Disability, the Company may give the Executive written notice of its intention to terminate
the Executive’s employment. In that event, the Executive’s employment with the Company shall terminate, effective on the later of the thirtieth (30th) day after receipt of such

 5 

 accordance with the terms and conditions of such employee benefit plans, programs or arrangements. Any equity
awards granted to the Executive shall continue to be governed by the terms and conditions of the applicable plans and agreements. The payments and benefits described in this Section 5 shall be the only payments and benefits payable in the event
of the Executive’s termination of employment for any reason. 
  

	 	6.	Confidential Information. 

 (a) The Executive shall not disclose or use at any
time, either during his employment or thereafter, any Trade Secrets and Confidential Information of which he becomes aware, whether or not such information is developed by the Executive, except to the extent that such disclosure or use is directly
related to and required by the Executive’s performance in good faith of duties for the Company Group. The Executive will take all appropriate steps to safeguard Trade Secrets and Confidential Information in his possession and to protect it
against disclosure, misuse, espionage, loss and theft. The Executive shall deliver to the Company at the termination of his employment, or at any time the Company may request, all memoranda, notes, plans, records, reports, computer tapes and
software and other documents and data (and copies thereof) relating to the Trade Secrets and Confidential Information or the Work Product of the business of the Company Group which the Executive may then possess or have under his control.
Notwithstanding the foregoing, the Executive may truthfully respond to a lawful and valid subpoena or other legal process, but shall give the Company the earliest possible notice thereof. 

(b) All Work Product that the Executive may have discovered, invented or originated during his employment by any Company Group Member(s) prior
to such employment, that the Executive may discover, invent or originate during his employment or at any time following the termination of his or her employment with the applicable Company Group Member(s), shall be the exclusive property of the
Company Group, and the Executive hereby assigns all of his right, title and interest in and to such Work Product to the Company or the applicable Company Group Member, including all intellectual property rights therein. The Executive shall promptly
disclose all Work Product to the Company, shall execute at the request of the Company any assignments or other documents the Company may deem necessary to protect or perfect its (or any Company Group Member’s as applicable) rights therein, and
shall assist the Company, at the Company’s expense, in obtaining, defending and enforcing the Company’s (or any Company Group Member’s, as applicable) rights therein. The Executive hereby appoints the Company as his attorney-in-fact
to execute on his behalf any assignments or other documents deemed necessary by the Company to protect or perfect each Company Group Member’s rights to any Work Product. 

(c) The Executive acknowledges that the covenants contained in this Section 6 are an essential element of this Agreement and are being
provided in consideration of the compensation provided under this Agreement, and that any breach by the Executive of any provision of this Section 6 will result in irreparable injury to the Company Group Members. The Executive acknowledges that
in the event of such a breach, in addition to all other remedies available at law, the Company shall be entitled to equitable relief, including injunctive relief, without the necessity of proving actual damages or posting a bond therefor. 

  
 6 

 7. Assignment and Successors. The Company may assign its rights and obligations
under this Agreement to any entity, including any successor to all or substantially all the assets of the Company, by merger or otherwise, and may assign or encumber this Agreement and its rights hereunder as security for indebtedness of the Company
and its Affiliates. The Executive may not assign the Executive’s rights or obligations under this Agreement to any individual or entity. This Agreement shall be binding upon and inure to the benefit of the Company, the Executive and their
respective successors, assigns, personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. 

8. Governing Law. All issues and questions concerning the application, construction, validity, interpretation and enforcement of
this Agreement shall be governed, construed, interpreted and enforced in accordance with the substantive laws of the State of Ohio, without giving effect to any principles of conflicts of law, whether of the State of Ohio or any other jurisdiction,
and where applicable, the laws of the United States, that would result in the application of the laws of any other jurisdiction. 
 9.
Validity. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 

10. Notices. Any notice, request, claim, demand, document and other communication hereunder to any party hereto
shall be effective upon receipt (or refusal of receipt) and shall be in writing and delivered personally or sent by telex, telecopy, or certified or registered mail, postage prepaid, to the following address (or at any other address as any party
hereto shall have specified by notice in writing to the other party hereto): 
  

	 	(a)	If to the Company:

	 	  	Cincinnati, Ohio 45227 

	 	  	Attn: General Counsel 

	 	  	Facsimile: (513) 579-0444 

  

	 	(b)	If to the Executive, at the address set forth on the signature page hereto. 

 11.
Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, but all of which together will constitute one and the same Agreement. 

12. Entire Agreement. As of the Effective Date, this Agreement shall supersede and replace the Prior Employment Agreement, and
the Prior Employment Agreement shall be null and void and of no further force or effect. The terms of this Agreement (together with any other agreements and instruments contemplated hereby or referred to herein (other than the Prior Employment
Agreement)) are intended by the parties hereto to be the final expression of their agreement with respect to the employment of the Executive by the Company and may not be contradicted by evidence of any prior or contemporaneous agreement (including,
without limitation, any term sheet or offer letter); provided, however, that the provisions in this 

  
 7 

 Agreement are not intended to limit or extinguish any restrictive covenants in any other agreement or arrangement
between the Executive and the Company or any of its Affiliates. The parties hereto further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in
any judicial, administrative, or other legal proceeding to vary the terms of this Agreement. 
 13. Amendments; Waivers. This
Agreement may not be modified, amended, or terminated except by an instrument in writing, signed by the Executive and a duly authorized officer of the Company and approved by the Board, which expressly identifies the amended provision of this
Agreement. By an instrument in writing similarly executed and approved by the Board, the Executive or a duly authorized officer of the Company may waive compliance by the other party or parties hereto with any provision of this Agreement that such
other party was or is obligated to comply with or perform; provided, however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure to comply or perform. No failure to exercise
and no delay in exercising any right, remedy, or power hereunder shall preclude any other or further exercise of any other right, remedy, or power provided herein or by law or in equity. 

14. No Inconsistent Actions. The parties hereto shall not voluntarily undertake or fail to undertake any action or course of
action inconsistent with the provisions or essential intent of this Agreement. Furthermore, it is the intent of the parties hereto to act in a fair and reasonable manner with respect to the interpretation and application of the provisions of this
Agreement. 
 15. Construction. This Agreement shall be deemed drafted equally by both of the parties hereto. Its language
shall be construed as a whole and according to its fair meaning. Any presumption or principle that the language is to be construed against any party hereto shall not apply. The headings in this Agreement are only for convenience and are not intended
to affect construction or interpretation. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. Also, unless the context clearly indicates to
the contrary, (a) the plural includes the singular and the singular includes the plural; (b) “and” and “or” are each used both conjunctively and disjunctively; (c) “any,” “all,”
“each,” or “every” means “any and all,” and “each and every”; (d) “includes” and “including” are each “without limitation”; (e) “herein,” “hereof,”
“hereunder” and other similar compounds of the word “here” refer to the entire Agreement and not to any particular paragraph, subparagraph, section or subsection; and (f) all pronouns and any variations thereof shall be
deemed to refer to the masculine, feminine, neuter, singular or plural as the identity of the Persons referred to may require. 
 16.
Enforcement. If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the
illegal, invalid or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall 

  
 8 

 be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable. 
 17. Withholding. The Company and its
Affiliates shall be entitled to withhold from any amounts payable under this Agreement, any federal, state, local or foreign withholding or other taxes or charges that the Company or any of its Affiliates is required to withhold. The Company and its
Affiliates shall be entitled to rely on an opinion of counsel if any questions as to the amount or requirement of withholding shall arise. 

18. Absence of Conflicts; Executive Acknowledgement; Confidentiality. The Executive hereby represents that from and after the
Effective Date the performance of the Executive’s duties hereunder will not breach any other agreement to which the Executive is a party. The Executive acknowledges that the Executive has read and understands this Agreement, is fully aware of
its legal effect, has not acted in reliance upon any representations or promises made by the Company or any of its Affiliates other than those contained in writing herein, and has entered into this Agreement freely based on the Executive’s own
judgment. The Executive agrees not to disclose the terms or existence of this Agreement to any Person unless the Company agrees to such disclosure in advance and in writing; provided that the Executive may, without such permission, make such
disclosures as are required by applicable law, including disclosures to taxing agencies, and disclose the terms of this Agreement to the Executive’s attorney(s), accountant(s), tax advisor(s), and other professional service provider(s), and to
members of the Executive’s immediate family, as reasonably necessary; provided, further, that the Executive instructs such Person(s) that the terms of this Agreement are strictly confidential and are not to be revealed to anyone
else except as required by applicable law. 
 19. Survival. The expiration or termination of the Term shall not impair
the rights or obligations of any party hereto which shall have accrued prior to such expiration or termination (including, without limitation, pursuant to the provisions of Section 6 hereof). 

 

	 	20.	Section 409A. 

 (a) General. The parties hereto acknowledge and agree
that, to the extent applicable, this Agreement shall be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event that the
Company determines that any amounts payable hereunder will be immediately taxable to the Executive under Section 409A, the Company reserves the right (without any obligation to do so or to indemnify the Executive for failure to do so) to
(i) adopt such amendments to this Agreement and appropriate policies and procedures, including amendments and policies with retroactive effect, that the Company determines to be necessary or appropriate to preserve the intended tax treatment of
the benefits provided by this Agreement, to preserve the economic benefits of this Agreement and to avoid less favorable accounting or tax consequences for the Company and/or (ii) take such other actions as the Company determines to be
necessary or appropriate to exempt the amounts payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder. Notwithstanding anything herein to the
contrary, in no event shall any liability for failure to comply with the requirements of Section 409A be transferred from the Executive or any other individual to the Company or any of its Affiliates, employees or agents pursuant to the terms
of this Agreement or otherwise.

 (b) Miscellaneous. To the extent that any reimbursement of expenses or in-kind benefits
constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31 of the year following the year in which the expense was incurred. The amount of expenses eligible
for reimbursement, or in-kind benefits provided, in one year shall not affect the amount eligible for reimbursement, or in-kind benefits provided, in any other year. The Executive’s right to reimbursement of any such expenses or such in-kind
benefits shall not be subject to liquidation or exchange for any other benefit. Notwithstanding any provision to the contrary in this Agreement, if the Executive is deemed at the time of his separation from service to be a “specified
employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the termination benefits to which the Executive is entitled under this Agreement is required in order to avoid a
prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of the Executive’s termination benefits shall not be provided to the Executive prior to the earlier of (A) the expiration of the six-month period
measured from the date of the Executive’s “separation from service” with the Company (as such term is defined in the Department of Treasury regulations issued under Section 409A of the Code) and (B) the date of the
Executive’s death; upon the earlier of such dates, all payments and benefits deferred pursuant to this sentence shall be paid in a lump sum to the Executive, and any remaining payments and benefits due under the Agreement shall be paid as
otherwise provided herein. The determination of whether the Executive is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of his separation from service shall be made by the Company in
accordance with the terms of Section 409A (including, without limitation, Section 1.409A-1(i) of the Department of Treasury regulations). 

21. Compensation Recovery Policy. The Executive acknowledges and agrees that, to the extent the Company adopts any clawback or
similar policy pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act or otherwise, and any rules and regulations promulgated thereunder, he shall take all action necessary or appropriate to comply with such policy (including,
without limitation, entering into any further agreements, amendments or policies necessary or appropriate to implement and/or enforce such policy).
