Registrations in which the Company shall pay all Registration Expenses whether or not any such Short-Form Registration has become effective; provided that the aggregate offering value of the Registrable Securities requested to be registered
in any Short-Form Registration must equal at least $25,000,000. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form registration and if the managing underwriters (if any) agree to

Registrable Securities and to remain qualified so that Short-Form Registrations continue to be available for such offer and sale. If the Majority Whitney Holders and the Majority Bain Holders request that a Short-Form Registration be filed pursuant
to Rule 415 (a “Shelf Registration”) and the Company is eligible to do so, the Company shall use its reasonable best efforts to cause the Shelf Registration to be declared effective under the Securities Act as soon as practicable
after filing, and, if the Company is a WKSI at the time of any such request, to cause such Shelf Registration to be an Automatic Shelf Registration Statement, and once effective, the Company shall cause the Shelf Registration to remain effective
(including by filing a new Shelf Registration, if necessary) for a period ending on the earlier of (i) the date on which all Registrable Securities included in such registration have been sold or distributed pursuant to the Shelf Registration,
(ii) the date as of which there are no longer in existence any Registrable Securities covered by the Shelf Registration and (iii) an earlier date agreed to in writing by both the Majority Whitney Holders and the Majority Bain Holders. If
for any reason the Company ceases to be a WKSI or becomes ineligible to utilize Form S-3, the Company shall prepare and file with the Securities and Exchange Commission a registration statement or registration statements on such form that is
available for the sale of Registrable Securities. 
 (d)    Resale Shelf Registration. Unless the Major Sponsors
instruct the Company otherwise in writing prior to such registration statement becoming effective, on the first day of the calendar month immediately following the first anniversary of the IPO, or as promptly as practicable thereafter, so long as
the Company is then-eligible to use any applicable short-form registration, the Company shall use its reasonable best efforts to cause a registration statement for the sale or distribution by the Sponsors and other holders of Registrable Securities
approved by the Majority Whitney Holders and the Majority Bain Holders of all of the Registrable Securities held by such holders on a delayed or continuous basis pursuant to Rule 415, including by way of an underwritten offering, block sale or other
distribution plan (the “Resale Shelf Registration”), to be filed and declared effective under the Securities Act, and, if the Company is a WKSI at the time of such Resale Shelf Registration, to cause that such Resale Shelf
Registration to be an Automatic Shelf Registration Statement, and once effective, the Company shall cause the Resale Shelf Registration to remain effective (including by filing a new Resale Shelf Registration, if necessary) for a period ending on
the earlier of (i) the date on which all Registrable Securities included in such registration have been sold or distributed pursuant to the Resale Shelf Registration, (ii) the date as of which there are no longer in existence any
Registrable Securities covered by the Shelf Registration and (iii) an earlier date agreed to in writing by both the Majority Whitney Holders and the Majority Bain Holders. The Company shall pay all Registration Expenses in connection with the

Registration or any Shelf Registration at any time during which the Company is ineligible to use any applicable short-form registration; provided that at such time, pursuant to Section 2(c), the Company shall use its reasonable
best efforts to become and remain eligible to use Short-Form Registrations and, upon the request of the Majority Whitney Holders or the Majority Bain Holders pursuant to this Section 2, the Company shall prepare and file with the

 (e)    Shelf Takedowns. At any time when the Resale Shelf
Registration or a Shelf Registration is effective and its use has not been otherwise suspended by the Company in accordance with the terms of Section 2(c) or Section 2(d) above, upon a written demand (a “Takedown
Demand”) by any Whitney Sponsor or Bain Sponsor that is a Shelf Participant holding Registrable Securities at such time (the “Initiating Sponsor”), the Company will facilitate in the manner described in this Agreement a
“takedown” of Registrable Securities off of such Resale Shelf Registration or Shelf Registration and the Company shall pay all Registration Expenses in connection therewith; provided that the Company will provide (x) in
connection with any non-marketed underwritten takedown offering (other than a Block Trade) or non-underwritten takedown offering, at least two (2) Business Days’ notice of such Takedown Demand to each Whitney Sponsor and Bain Sponsor

Block Trade, by 10:00 p.m. Eastern time on the date notice is given to such participant and (C) in the case of a marketed underwritten takedown offering, three (3) Business Days following the date notice is given to such participant), the
Initiating Sponsor and the other Shelf Participants that request inclusion of their Registrable Securities shall be entitled to sell their Registrable Securities in such offering (x) in connection with any non-underwritten takedown offering, on
a pro rata basis based on the amount of Registrable Securities owned by all such Shelf Participants requesting to include Registrable Securities in such non-underwritten takedown offering as of the date the Company provided notice of the Takedown
Demand to the Shelf Participants pursuant to this Section 2(e) and (y) in connection with any underwritten takedown offering, subject to Section 2(f) below. Each holder of Registrable Securities that is a Shelf
Participant agrees that such holder shall treat as confidential the receipt of the notice of a Takedown Demand and shall not disclose or use the information contained in such notice without the prior written consent of the Company until such time as
the information contained therein is or becomes available to the public generally, other than as a result of disclosure by the holder in breach of the terms of this Agreement. 

(f)    Priority on Demand Registrations and Takedown Offerings. The Company shall not include in any Demand
Registration any securities which are not Registrable Securities without the prior written consent of the Applicable Approving Party. If a Demand Registration or a takedown offering is an underwritten offering and the managing underwriters advise
the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any,
which can be sold therein without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such offering prior to the inclusion of any securities which are not
Registrable Securities (i) first, the number of Sponsor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on
the basis of the amount of Registrable Securities owned by each such holder relative to the total number of Registrable Securities held by all 

  
 -8- 














 
such holders of Sponsor Registrable Securities requesting to include Registrable Securities in such Demand Registration or takedown offering as of the date the Company provided written notice of
the Demand Registration or Takedown Demand to the holders of Registrable Securities, without distinguishing between holders based on who initially requested such Demand Registration or Takedown Demand or otherwise, and (ii) second, the number
of Executive Registrable Securities and Other Investor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on the
basis of the amount of Registrable Securities owned by each such holder relative to the total number of Registrable Securities held by all such holders of Executive Registrable Securities and Other Investor Registrable Securities requesting to
include Registrable Securities in such Demand Registration or takedown offering as of the date the Company provided written notice of the Demand Registration or Takedown Demand to the holders of Registrable Securities. 

(g)    Restrictions on Demand Registrations and Takedown Offerings. Any demand for the filing of a registration
statement or for a registered offering (including a takedown offering) hereunder will be subject to the constraints of any applicable lock-up arrangements, and any such demand must be deferred until such lock-up arrangements no longer apply. 

(i)    The Company shall not be obligated to effect any Demand Registration within 180 days after the effective date of a
previous Demand Registration or a previous registration in which Registrable Securities were included pursuant to Section 3. The Company may postpone, for up to 60 days from the date of the request (the “Suspension
Period”), the filing or the effectiveness of a registration statement for a Demand Registration or suspend the use of a prospectus that is part of the Resale Shelf Registration or any Shelf Registration (and therefore suspend sales of the
Registrable Securities included therein) by providing written notice to the holders of Registrable Securities if the Company and the Applicable Approving Party agree 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 or disposition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation,
tender offer, recapitalization, reorganization or similar transaction or would require the Company to disclose any material nonpublic information which would reasonably be likely to be detrimental to the Company and its Subsidiaries; provided
that in such event, the holders of Registrable Securities initially requesting such Demand Registration or Takedown Demand shall be entitled to withdraw such request. The Company may delay or suspend the effectiveness of a Demand Registration or
takedown offering pursuant to this Section 2(g)(i) only once in any twelve-month period; provided that, for the avoidance of doubt, the Company may in any event delay or suspend the effectiveness of Demand Registration or takedown
offering in the case of an event described under Section 5(a)(vi) to enable it to comply with its obligations set forth in Section 5(a)(vi). The Company may extend the Suspension Period for an additional consecutive 60 days
with the consent of the Applicable Approving Party, which consent shall not be unreasonably withheld. 
 (ii)    In the
case of an event that causes the Company to suspend the use of the Resale Shelf Registration or any Shelf Registration as set forth in Section 2(g)(i) or pursuant to Section 5(a)(vi) (a “Suspension Event”),
the Company shall give a notice to the holders of Registrable Securities registered pursuant to such Resale Shelf Registration or Shelf Registration (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. A holder of Registrable Securities shall not effect any sales of the Registrable
Securities pursuant to such Resale Shelf Registration or Shelf Registration (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). Each holder
of Registrable Securities agrees that such holder shall treat as confidential the receipt of the Suspension Notice and shall not disclose or use the information contained in such 

  
 -9- 














 
Suspension Notice without the prior written consent of the Company until such time as the information contained therein is or becomes available to the public generally, other than as a result of
disclosure by such holder in breach of the terms of this Agreement. The holders of Registrable Securities may recommence effecting sales of the Registrable Securities pursuant to the Resale Shelf Registration or Shelf Registration (or such filings)
following further 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 of Registrable Securities and to such holders’
counsel, if any, promptly following the conclusion of any Suspension Event. 
 (iii)    Notwithstanding any provision
herein to the contrary, if the Company shall give a Suspension Notice with respect to the Resale Shelf Registration or any Shelf Registration pursuant to this Section 2(g), the Company agrees that it shall extend the period of time
during which such Resale Shelf Registration or Shelf Registration shall be maintained effective pursuant to this Agreement by the number of days during the period from the date of receipt by the holders of the Suspension Notice to and including the
date of receipt by the holders of the End of Suspension Notice and provide copies of the supplemented or amended prospectus necessary to resume sales, with respect to each Suspension Event; provided that such period of time shall not be extended
beyond the date that Common Stock covered by such Resale Shelf Registration or Shelf Registration are no longer Registrable Securities. 

(h)    Selection of Underwriters. In connection with any Demand Registration, the Applicable Approving Party shall
have the right to select the investment banker(s) and manager(s) to administer the offering. If any takedown offering is an underwritten offering, the Applicable Approving Party shall have the right to select the investment banker(s) and manager(s)
to administer such takedown offering. In each case, the Applicable Approving Party shall have the right to approve the underwriting arrangements with such investment banker(s) and manager(s) on behalf of all holders of Registrable Securities
participating in such offering. 
 (i)    Other Registration Rights. The Company represents and warrants that
other than the Stockholders Agreement, 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 any Subsidiary, or any securities convertible or exchangeable into or exercisable for such securities, without
the prior written consent of the Major Sponsors. 
 (j)    Revocation of Demand Notice or Takedown Notice. At any
time prior to the effective date of the Registration Statement relating to a Demand Registration or the “pricing” of any offering relating to a Takedown Demand, the holders of Registrable Securities that requested such Demand Registration
or takedown offering may revoke such request for a Demand Registration or takedown offering on behalf of all holders of Registrable Securities participating in such Demand Registration or takedown offering without liability to such holders of
Registrable Securities, in each case by providing written notice to the Company; provided that if both Sponsors are participating in such Demand Registration or takedown offering and the non-requesting Sponsor otherwise has the right to make
a Demand Registration or takedown offering pursuant to Section 2 and desires to continue to participate in such Demand Registration or takedown offering, then the revocation shall only apply to the requesting Sponsor.

 Section 3.     Piggyback Registrations. 

(a)     Right to Piggyback. Whenever the Company proposes to register any of its securities under the Securities Act
(other than (i) pursuant to a Demand Registration, in which case the ability of a holder of Registrable Securities to participate in such Demand Registration is addressed by Section 2(a), (ii) pursuant to a Takedown Demand, in
which case the ability of a holder of Registrable Securities to participate in such takedown offering is addressed by Section 2(e), (iii) with respect to the holders of Executive Registrable Securities and the holders of Other
Investor Registrable Securities, in connection with the IPO, (iv) with respect to the holders of Sponsor Registrable Securities, with the written consent of the Major Sponsors, in connection with the IPO, if no Registrable Securities of the
Major Sponsors are included in the IPO, (v) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange Commission (or any successor or similar forms), (vi) in connection with a registration the primary
purpose of which is to register debt securities, or (vii) 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 Registrable Securities of its
intention to effect such Piggyback Registration and, subject to the terms of Section 3(c) and Section 3(d), 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 with respect to which the Company has received written requests for inclusion therein within 20 days after delivery of the Company’s notice; provided that any such other holder
may withdraw its request for inclusion at any time prior to executing the underwriting agreement or, if none, prior to the applicable registration statement becoming effective. 

(b)     Piggyback Expenses. The Registration Expenses of the holders of Registrable Securities shall be paid by the
Company in all Piggyback Registrations, whether or not any such registration became effective. 
 (c)     Priority on
Primary 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 number of Sponsor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse
effect, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder relative to the total number of Registrable Securities held by all such holders of Sponsor Registrable Securities
requesting to include Registrable Securities in such registration as of the date the Company provided written notice of the Piggyback Registration to the holders of Registrable Securities, (iii) third, the number of Executive Registrable
Securities and Other Investor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on the basis of the amount of
Registrable Securities owned by each such holder relative to the total number of Registrable Securities held by all such holders of Executive Registrable Securities and Other Investor Registrable Securities requesting to include Registrable
Securities in such registration as of the date the Company provided written notice of the Piggyback Registration to the holders of Registrable Securities, and (iv) fourth, 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)     Priority on Secondary
Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities (it being understood 

  
 -11- 














 
that Demand Registrations and Shelf Registrations (including any related takedown offerings) by or on behalf of holders of Registrable Securities are addressed in Section 2 rather
than in this Section 3(d)), 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 requested to be included therein by the holders
initially requesting such registration and the number of Sponsor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof
on the basis of the amount of securities owned by each such holder relative to the total number of securities held by all such holders initially requesting such registration and holders of Sponsor Registrable Securities requesting to include
Registrable Securities in such registration as of the date the Company provided written notice of the Piggyback Registration to the holders of Registrable Securities, (ii) second, the number of Executive Registrable Securities and Other
Investor Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities
owned by each such holder relative to the total number of Registrable Securities held by all such holders of Executive Registrable Securities and Other Investor Registrable Securities requesting to include Registrable Securities in such registration
as of the date the Company provided written notice of the Piggyback Registration to the holders of Registrable Securities, 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. 
 Section 4.     Holdback Agreements. 

(a)     Holders of Registrable Securities. If required by the Applicable Approving Party, each holder of Registrable
Securities (in the case of any underwritten Public Offering) shall enter into lock-up agreements with the managing underwriter(s) of such underwritten Public Offering in such form as agreed to by the Applicable Approving Party. In the absence of any
such lock-up agreement: 
 (i)     each holder of Registrable Securities agrees that in connection with the
Company’s IPO, such Person shall not (A) offer, sell, contract to sell, pledge or otherwise dispose of (including sales pursuant to Rule 144), directly or indirectly, any Capital Stock of the Company (including Capital Stock of the Company

same effect as described in clause (A) above, (C) enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences or ownership of any Securities, whether such transaction is to be
settled by delivery of such Securities, in cash or otherwise (each of (A), (B) and (C) above, a “Sale Transaction”), or (D) publicly disclose the intention to enter into any Sale Transaction, from the date on which
the Company gives notice to the holders of Registrable Securities that a preliminary prospectus has been circulated for such IPO to the date that is 180 days following the date of the final prospectus for such IPO (the “Holdback
Period”), unless the Applicable Approving Party and the underwriters managing the IPO otherwise agree in writing; 

(ii)     each holder of Registrable Securities agrees that in connection with all other underwritten Public Offerings
other than the IPO, such Person shall not effect any Sale Transaction from 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 to the
date that is 90 days following the date of the final prospectus for such Public Offering (“Follow-On Holdback Period”), unless, if an underwritten Public Offering, the Applicable Approving Party and the underwriters managing such
Public Offering otherwise agree in writing. 

  
 -12- 














 The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the restrictions set forth in this Section 4(a) until the end of such period. 

(b)     The Company. 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 or Follow-On Holdback Period, and (ii) shall use its reasonable best efforts to cause (A) each holder of at least 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) and (B) each of its directors and executive officers to agree not to effect any Sale Transaction or publicly disclose
the intention to enter into any Sale Transaction during any Holdback Period or Follow- On Holdback Period, except as part of such underwritten registration, if otherwise permitted, unless the underwriters managing the Public Offering otherwise agree
in writing. 
 Section 5.     Registration Procedures. 

(a)     Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered

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 not in any event 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)

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) consent to general service of process in any such jurisdiction or (C) 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 request by the Securities and Exchange Commission for the amendment or
supplementing of such registration statement or prospectus or for additional information, 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(g), at the request of any
such seller, the Company shall use its reasonable best efforts to 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

all such other actions as the Applicable Approving Party or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including, without limitation, effecting a stock split,
combination of shares, recapitalization or reorganization); 
 (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

 -14- 














 (xi)     take all reasonable actions to ensure that any Free-Writing
Prospectus utilized in connection with any Demand Registration (including any Shelf 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 its 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)     permit any holder of Registrable Securities which holder, in its sole and exclusive judgment, might be deemed
to be an underwriter or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to 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
registration statement for sale in any jurisdiction use reasonable best efforts promptly to obtain the withdrawal of such order; 

(xv)     use its reasonable best efforts to cause such Registrable Securities covered by such registration statement to
be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; 

(xvi)     cooperate with the holders of Registrable Securities covered by the registration statement and the managing
underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement and enable such securities to be in such
denominations and registered in such names as the managing underwriter, or agent, if any, or such holders may request; 

(xvii)     cooperate with each holder of Registrable Securities covered by the registration statement and each
underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA; 

(xviii)     use its reasonable best efforts to make available the executive officers of the Company to participate with
the holders of Registrable Securities and any underwriters in any “road shows” or other selling efforts that may be reasonably requested by the holders in connection with the methods of distribution for the Registrable Securities; 

  
 -15- 














 (xix)     in the case of any underwritten offering, use its reasonable

requests; 
 (xx)     in the case of any underwritten offering, use its reasonable best efforts to provide a legal

to the registration statement, each amendment and supplement thereto, the prospectus included therein (including the preliminary prospectus) and such other documents relating thereto in customary form and covering such matters of the type
customarily covered by legal opinions of such nature, which opinion shall be addressed to the underwriters and the holders of such Registrable Securities; 

(xxi)     if the Company files an Automatic Shelf Registration Statement covering any Registrable Securities, use its
reasonable best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405)) during the period during which such Automatic Shelf Registration Statement is required 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; and 

(xxiii)     subject to the terms of Section 2(c) and Section 2(d), if an Automatic Shelf
Registration Statement has been outstanding for at least three years, at the end of the third year, refile a new Automatic Shelf Registration Statement covering the Registrable Securities, and, if at any time when the Company is required to
re-evaluate its WKSI status the Company determines that it is not a WKSI, use its reasonable best efforts to refile the registration statement on Form S-3 and keep such registration statement effective (including by filing a new Resale Shelf

the Suspension Period and to file and cause to become effective or terminate the suspension of use or effectiveness, as the case may be, of the subject registration statement. 

(c)     If the Company files any Automatic Shelf Registration Statement for the benefit of the holders of any of its
securities other than the holders of Registrable Securities, and the Whitney Holders or the Bain Holders do not request that their Registrable Securities be included in such Shelf Registration, the Company agrees that, at the request of the Majority
Whitney Holders and/or the Majority Bain Holders, it shall include in such Automatic Shelf Registration Statement such disclosures as may be required by Rule 430B in order to ensure that the Whitney Holders and/or the Bain Holders may be added to
such Shelf Registration at a later time through the filing of a prospectus supplement rather than a post-effective amendment.

 Section 6.     Registration Expenses. 

(a)     The Company’s Obligation. All expenses incident to the Company’s performance of or compliance with
this Agreement (including, without limitation, all registration, qualification and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of
custodians, and fees and disbursements of counsel for the Company and all independent certified public accountants, underwriters (excluding underwriting discounts and commissions) and other Persons retained by the Company) (all such expenses being
herein called “Registration Expenses”), shall be borne by the Company, and, for the avoidance of doubt, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which
similar securities issued by the Company are then listed. Each Person that sells securities pursuant to a Demand Registration, a Takedown Demand or Piggyback Registration hereunder shall bear and pay all underwriting discounts and commissions and
transfer taxes 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 takedown offering that is an underwritten offering in which Whitney Holders and/or Bain Holders participate, the Company shall reimburse each of the
Whitney Holders and/or Bain Holders (as applicable) participating in such registration for the reasonable fees and disbursements of one separate counsel and one separate local counsel (if necessary) chosen by each of the Majority Whitney Holders and
the Majority Bain Holders (as applicable). In connection with each registration in which neither the Whitney Holders nor the Bain Holders participate, the Company shall reimburse the holders of Registrable Securities included in such registration
for the reasonable fees and disbursements of one counsel and one local counsel (if necessary) chosen by the holders of a majority of the Registrable Securities included in such registration for the purpose of rendering a legal opinion on behalf of
such holders in connection with any underwritten Demand Registration, takedown offering or Piggyback Registration. 

(c)     Security Holders. To the extent Registration Expenses are not required to be paid by the Company, each
holder of securities included in any registration hereunder shall pay those Registration Expenses allocable to the registration of such holder’s securities so included, and any Registration Expenses not so allocable shall be borne by all
sellers of securities included in such registration in proportion to the aggregate selling price of the securities to be so registered. 

Section 7.     Indemnification and Contribution. 

(a)     By the Company. The Company shall indemnify and hold harmless, to the extent permitted by law, each holder
of Registrable Securities, such holder’s officers, directors employees, agents and representatives, and each Person who controls such holder (within the meaning of the Securities Act) (the “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 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 

  
 -17- 














 
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 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 Indemnified Party
expressly for use therein or by such 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 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 Indemnified Parties. 
 (b)     By Each
Security Holder. In connection with any registration statement in which a holder of Registrable Securities 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, 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 actually 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 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 of a majority of the Registrable Securities included in the registration if such holders are
indemnified parties, at the expense of the indemnifying party. 

  
 -18- 














 (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(f) 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 a release of such indemnified party by the claimant or plaintiff from all liability in respect to such claim or litigation. 

(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.

 Section 8.     Underwritten Registrations. No Person may
participate in any registration 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 of Registrable Securities 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, custody agreements, stock powers, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements. Each holder of Registrable Securities 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 or that are necessary to give further effect thereto. To the extent that any such agreement is entered into pursuant to, and consistent with,
Section 4 and this Section 8, 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. 
 Section 9.     Additional Parties; Joinder. 

(a) Subject to the prior written consent of the Majority Whitney Holders and the Majority Bain Holders, the Company may permit any Person who
acquires Common Stock or rights to acquire Common Stock from the Company after the date hereof 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 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 Common Stock acquired by
such Person (the “Acquired Shares”) shall be Sponsor Registrable Securities, Executive Registrable Securities or Other Investor Registrable Securities, as determined by the Major Sponsors, such Person shall be a “holder of
Registrable Securities” under this Agreement with respect to the Acquired Shares, and the Company shall add such Person’s name and address to the appropriate schedule hereto and circulate such information to the parties to this Agreement.

 (b)     Notwithstanding anything to the contrary contained herein, except in the case of (i) a transfer to the
Company, (ii) a transfer by any Sponsor to its limited partners or members following which such limited partners or members will not hold Registrable Securities, (iii) a Public Offering, (iv) a sale pursuant to Rule 144 after the
completion of the IPO or (v) a transfer in connection with a Sale of the Company, prior to transferring any Registrable Securities to any Person (including, without limitation, by operation of law), the transferring holder shall cause the
prospective transferee to execute and deliver to the Company a Joinder agreeing to be bound by the terms of this Agreement. Any transfer or attempted transfer of any Registrable Securities in violation of any provision of this Agreement or the
Stockholders Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Registrable Securities as the owner thereof for any purpose. 

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 or holders of Registrable Securities 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 of Restricted Securities 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, the Company distributes securities of such Subsidiary to its 

  
 -20- 














 
equity holders, 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.     Legend. Each
certificate evidencing any Registrable Securities and each certificate issued in exchange for or upon the transfer of any Registrable Securities (unless such Registrable Securities would no longer be Registrable Securities after such transfer) shall
be stamped or otherwise imprinted with a legend in substantially the following form: 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO RESTRICTIONS ON TRANSFER AND OTHER PROVISIONS SET FORTH IN A REGISTRATION RIGHTS AGREEMENT DATED AS OF MARCH 16, 2017 AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S STOCKHOLDERS,
AS AMENDED. A COPY OF SUCH REGISTRATION RIGHTS AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.” 

The Company shall imprint such legend on certificates evidencing Registrable Securities outstanding prior to the date hereof. The legend set forth above shall
be removed from the certificates evidencing any securities that have ceased to be Registrable Securities. 

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 each Sponsor holding at least 1% of the outstanding shares of voting Common Stock on a fully-diluted basis; provided that no such amendment, modification or waiver that by its terms
would materially and adversely affect a holder or group of holders of Registrable Securities in a manner materially different than any other holder or group of holders of Registrable Securities shall be effective against such holder or group of
holders of Registrable Securities without the consent of the holders of a majority of the Registrable Securities that are held by the group of holders that is materially and adversely affected thereby. 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 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. Notwithstanding anything to the contrary herein, no amendment to this Agreement in connection with an additional investment or a new investor shall be deemed to
adversely affect any class of Registrable Securities merely because of the addition of such new investor or amendments to account for the addition of such new investor or the terms of such investment, and, for the avoidance of doubt, differences
resulting from Stockholders holding different amounts or classes of Registrable Securities will not be deemed disproportionate for any purposes under this Agreement. 

(b)     Remedies. The parties to this Agreement shall be entitled to enforce their rights under this Agreement by
specific performance, injunctive relief and other equitable remedies (without posting a bond or other security or proving insufficiency of damages), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise
all other rights existing in their 

  
 -21- 














 
favor. The parties agree and acknowledge that (i) the Company and the Registrable Securities are unique, (ii) a breach of this Agreement would cause substantial and irreparable harm to
the Company and the non-breaching parties, (iii) money damages would not be an adequate remedy for any such breach and (iv) in addition to any other rights and remedies existing hereunder, any party shall be entitled to specific
performance, other injunctive relief and other equitable remedies from any court of law or equity of competent jurisdiction (without posting any bond or other security or proving insufficiency of damages) in order to enforce or prevent any 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 and in the Stockholders Agreement, this Agreement
(including all schedules, exhibits and annexes hereto) 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. Except as otherwise provided herein, this Agreement shall bind and inure to the
benefit of and be enforceable by the Company and its successors and permitted assigns and the holders of Registrable Securities and their respective successors and permitted assigns (whether so expressed or not), so long as such Persons hold
Registrable Securities. Except as otherwise set forth herein, the provisions of this Agreement which are for the benefit of purchasers or holders of Registrable Securities are also for the benefit of, and enforceable by, any subsequent holder of
Registrable Securities. 
 (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 (i) when delivered personally to the recipient, (ii) when sent to the recipient by confirmed electronic mail or facsimile if sent during
normal business hours of the recipient on a Business Day, 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) 3 Business Days
after it is deposited in the U.S. Mail, addressed to the recipient, first-class mail, return receipt requested. Such notices, demands and other communications shall be sent to the Company at the address specified below and to any holder of
Registrable Securities or to any other party subject to this Agreement at such address as indicated on Schedule of Sponsors hereto, or 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 giving written notice of the change to the sending party as provided herein.

(h)     Governing Law. All issues and questions concerning the construction, validity, interpretation and
enforcement of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether

interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

 (i)     MUTUAL WAIVER OF JURY TRIAL. AS A SPECIFICALLY BARGAINED FOR INDUCEMENT FOR EACH OF THE PARTIES HERETO

 (j)     CONSENT TO JURISDICTION AND SERVICE OF PROCESS. 

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, IF
(AND ONLY IF) THE COURT OF CHANCERY OF THE STATE OF DELAWARE DECLINES TO ACCEPT OR DOES NOT HAVE JURISDICTION OVER A PARTICULAR MATTER, THE SUPERIOR COURT OF THE STATE OF DELAWARE OR ANY FEDERAL COURT SITTING IN THE STATE OF DELAWARE) OVER ANY SUIT,
ACTION OR OTHER PROCEEDING BROUGHT BY ANY PARTY ARISING OUT OF OR RELATING TO THIS AGREEMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS WITH RESPECT TO ANY SUCH SUIT, ACTION OR OTHER PROCEEDING SHALL BE HEARD AND

BE EFFECTIVE SERVICE OF PROCESS FOR ANY ACTION, SUIT OR PROCEEDING WITH RESPECT TO ANY MATTERS TO WHICH IT HAS SUBMITTED TO JURISDICTION IN THIS SECTION. EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION TO THE LAYING

PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH SUIT, ACTION, OR OTHER PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

Registrable Securities agrees and acknowledges that no recourse under this 

  
 -24- 














 
Agreement or any documents or instruments delivered in connection with this Agreement, shall be had against any current or future director, officer, employee, agent, general or limited partner or
member of any holder of Registrable Securities or of any Affiliate or assignee thereof, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other 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 current or future director, officer, employee, agent, general or limited partner or member of any holder of
Registrable Securities or of any Affiliate or assignee thereof, as such, for any obligation of any holder of Registrable Securities under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based
on, in respect of or by reason of such obligations or their creation. 
 (l)     Descriptive Headings;
Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. The use of the word “including” in this Agreement shall be by way of example rather than by
limitation. 
 (m)     No Strict Construction. The language used in this Agreement shall be deemed to be the
language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party. 

(n)     Counterparts. This Agreement may be executed in multiple counterparts, any one of which need not contain
the signatures of more than one party, but all such counterparts taken together shall constitute one and the same agreement. 

(o)     Electronic Delivery. This Agreement, the agreements referred to herein, and each other agreement or
instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent executed and delivered by means of a photographic, photostatic, facsimile or similar reproduction of
such signed writing using a facsimile machine or electronic mail shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed
version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to
any such agreement or instrument shall raise the use of a facsimile machine or electronic mail to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or
electronic mail as a defense to the formation or enforceability of a contract and each such party forever waives any such defense. 

(p)     Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each holder
of Registrable Securities shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and the transactions
contemplated hereby. 
 (q)     No Inconsistent Agreements. The Company shall not hereafter enter into any
agreement with respect to its securities which violates the rights granted to, or is inconsistent with the rights or obligations of, the holders of Registrable Securities in this Agreement. 

(r)     No Third Party Beneficiaries. This Agreement shall be binding on each party hereto solely for the benefit
of each other party hereto and nothing set forth in this Agreement, express or implied, shall be construed to confer, directly or indirectly, upon or give to any Person other than the parties hereto from time to time any benefits, rights or remedies
under or by reason of, or any rights to enforce or cause the parties hereto to enforce, any provisions of this Agreement.
