unenforceable in any jurisdiction, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and
(b) the remainder of this Agreement and the application of such provision to other persons, entities or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the
validity or enforceability of such provision, or the application thereof, in any other jurisdiction. 
 Section 4.10
Enforcement. Each party hereto acknowledges that money damages would not be an adequate remedy in the event that any of the covenants or agreements in this Agreement are not performed in accordance with its terms, and it is therefore
agreed that in addition to and without limiting any other remedy or right it may have, the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any
court of competent jurisdiction enjoining any such breach and enforcing specifically the terms and provisions hereof. 

Section 4.11 Counterparts; Facsimile Signatures. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together shall constitute one instrument. This Agreement may be executed by facsimile, e-mail or .pdf format signature(s).

Transactions to the extent such costs are incurred for the benefit of all Pre-IPO Equityholders (including those incurred by the Company), as reasonably determined by the Company. Expenses incurred by any Pre-IPO Equityholders on its own behalf (including the fees and disbursements of counsel, advisors and other Persons retained by such Pre-IPO Equityholder) will not be

 Section 2. Registration Rights. 

2.1. Demand Registrations. 

(a) Demand Registrations Generally. This Section 2.1 sets forth the terms pursuant to which Advent, Spectrum
and the Krantz Holder may request registration under the Securities Act of all or any portion of the Registrable Securities held by such Holders on Form S-1 or similar long form registration (“Long
Form Registration”) and the Key Holders may request registration under the Securities Act of all or any portion of the Registrable Securities held by such Key Holders on Form S-3 or any similar short
form registration (“Short Form Registration”), if available. All registrations requested pursuant to this Section 2.1 are referred to herein as “Demand Registrations.” If the Company shall
receive from a written request that the Company file a Long Form Registration or with respect to all or a portion of the Registrable Securities (a “Demand Registration Request,”) and the sender(s) of such request pursuant to this
Agreement shall be known as the “Initiating Holder(s)”), then the Company shall, within ten (10) Business Days of the receipt thereof, give written notice (the “Demand Exercise Notice”) of such request to all

 5 

 (b) Long Form Registrations. At any time that the Company is not legally eligible to
file a registration statement with the SEC on Form S-3 or any similar short form registration statement, each of Advent, Spectrum and the Krantz Holder shall be entitled to request one (1) Long Form
Registration subject to Section 2.1(e), and the Company shall effect such Long Form Registrations pursuant to Section 2.4 and the Company shall pay all Expenses in connection with such Long Form
Registrations. 
 (c) Short Form Registrations. 

(i) In addition to the Long Form Registrations provided pursuant to Section 2.1(b), each Key Holder shall be entitled
to request an unlimited number of Short Form Registrations, the Company shall effect such Short Form Registrations pursuant to Section 2.4 and the Company shall pay all Expenses in connection with any such Short Form
Registration. The Company shall use its best efforts to make Short Form Registrations on Form S-3 available for the sale of Registrable Securities and if Short Form Registrations on Form S-3 are available for the sale of Registerable Securities, Advent, Spectrum and the Krantz Holder may only request registration on Form S-3. 

(ii) At any time that any Short Form Registration is effective, if any Holder or group of Holders holding Registrable Securities delivers a
notice to the Company (a “Take-Down Notice”) stating that it intends to effect an underwritten offering or distribution of all or part of its Registrable Securities included by it on any Short Form Registration (a “Shelf
Offering”) and stating the number of the Registrable Securities to be included in the Shelf Offering, then the Company shall amend or supplement the Short Form Registration as may be necessary in order to enable such Registrable Securities
to be distributed pursuant to the Shelf Offering (taking into account the inclusion of Registrable Securities by any other Holders thereof pursuant to this Section 2.1(c)(ii)). In connection with any Shelf Offering, the
Company shall, promptly after receipt of a Take-Down Notice, deliver such notice to all other Holders of Registrable Securities included in any Short Form Registration and permit each Holder to include its Registrable Securities included on a Short
Form Registration in the Shelf Offering if such Holder notifies the proposing Holders and the Company within 2 Business Days after delivery of the Take-Down Notice to such Holder, and in the event that the managing underwriter advises the Holders of
such securities in writing that in its or their view the total number or dollar amount of Registrable Securities proposed to be sold in such offering is such as to adversely affect the success of such offering (including, without limitation,
securities proposed to be included by other Holders of securities entitled to include securities in such offering pursuant to piggyback registration rights described in Section 2.2 hereof), the managing underwriter may
limit the number of shares which would otherwise be included in such Shelf Offering in the same manner as is described in Section 2.1(d). 

(iii) Notwithstanding the foregoing, if any of Advent, Spectrum, the Krantz Holder or 22C wishes to engage in an Underwritten Block Trade off
of a Shelf Registration Statement on Form S-3 (either through filing an automatic shelf registration statement or through a take-down from an already existing Shelf Registration Statement), then
notwithstanding the foregoing time periods, the Initiating Holder only needs to notify the Company of the Underwritten Block Trade not less than (i) two (2) business days prior to the day such offering is first anticipated to commence, in the
case of a take-down from an already existing Shelf Registration Statement on 

  
 6 

 
Form S-3, or (ii) twenty days (20) business days prior to the day such offering is first anticipated to commence, in the case of filing a new
Shelf Registration Statement on Form S-3. Advent, Spectrum, the Krantz Holder and 22C must elect whether or not to participate in such Underwritten Block Trade on the day such offering is to commence, and the
Company shall as expeditiously as possible use its reasonable best efforts (including co-operating with such Holders with respect to the provision of necessary information) to facilitate such Underwritten
Block Trade (which may close as early as two (2) Business Days after the date it commences), provided, that the Holder requesting such Underwritten Block Trade shall use commercially reasonable efforts to work with the Company and the
underwriters prior to making such request in order to facilitate preparation of offering documents related to the Underwritten Block Trade. For the avoidance of doubt, Holders other than Advent, Spectrum, the Krantz Holder and 22C shall not be
entitled to demand, receive notice of, or to elect to participate in, a Underwritten Block Trade or any Shelf Registration Statement or prospectus to be used in connection with such Underwritten Block Trade. 

(d) Demand Registration Priority. The Company shall not include in any Demand Registration any securities which are not Registrable
Securities without the prior written consent of the Majority Participating Holders included in such registration. If a Demand Registration 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 in an orderly manner
in such offering within a price range acceptable to the Majority Participating Holders to be included in such registration therein, without adversely affecting the marketability of the offering, the Company shall include in such registration prior
to the inclusion of any securities which are not Registrable Securities (i) first, the number of Registrable Securities requested to be included which in the opinion of such underwriters can be sold in an orderly manner within the price range
of such offering, pro rata among the respective Holders thereof on the basis of the number of Registrable Securities beneficially owned by each such Holder, and (ii) second, any other securities with respect to which the Company has granted
registration rights in accordance with Section 2.1(g) hereof requested to be included in such registration, pro rata among the respective Holders thereof on the basis of the amount of such securities requested to be
included therein by each such Holder. Without the consent of the Company and the Majority Participating Holders included in such registration, any Persons other than Holders of Registrable Securities who participate in Demand Registrations which are
not at the Company’s expense must pay their share of the Expenses as provided in Section 2.5 hereof. 
 (e)
Restrictions on Demand Registrations. The Company shall not be obligated to effect any Demand Registration (i) within thirty (30) days after a Demand Registration pursuant to this Section 2.1 that has been
declared or ordered effective, (ii) during the period any applicable restrictions are still in effect pursuant to any Lock-Up Agreement that has not been waived (or is not reasonably expected to be
waived) by the underwriters party thereto, (iii) if the Company shall furnish to such Holders a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board (after consultation with
external legal counsel), any registration of Registrable Securities should not be made or continued (or sales under a Shelf Registration Statement should be suspended) because (i) such registration (or continued sales under a Shelf Registration
Statement) would materially and adversely interfere with any existing or potential material financing, acquisition, corporate reorganization or merger or other material 

  
 7 

 
transaction or event involving the Company or any of its subsidiaries or (ii) the Company is in possession of material non-public information, the
premature disclosure of which has been determined by the Board to not be in the Company’s best interests (in either case, a “Valid Business Reason”) then (x) the Company may postpone filing a registration statement relating to a
Demand Registration Request or suspend sales under an existing Shelf Registration Statement until five Business Days after such Valid Business Reason no longer exists, but in no event for more than 60 days after the date the Board determines a Valid
Business Reason exists and (y) in the case a registration statement has been filed relating to a Demand Registration Request, if the Valid Business Reason has not resulted from actions taken by the Company, the Company may cause such
registration statement to be withdrawn and its effectiveness terminated or may postpone amending or supplementing such registration statement until five Business Days after such Valid Business Reason no longer exists, but in no event for more than
60 days after the date the Board determines a Valid Business Reason exists; and the Company shall give written notice to the Participating Holders of its determination to postpone or withdraw a registration statement or suspend sales under a Shelf
Registration Statement and of the fact that the Valid Business Reason for such postponement, withdrawal or suspension no longer exists, in each case, promptly after the occurrence thereof; provided, however, that the Company shall not defer its
obligation in this manner for more than (A) 60 days in any 90 day period or (B) for periods exceeding, in the aggregate, 90 days in any 12 month period, or (z) in the case of a Demand Registration, consisting of a Long Form Registration,
within 180 days after the effective date of a previous Long Form Registration or a previous registration in which the Holders of Registrable Securities were given piggyback rights pursuant to Section 2.2 and in which at
least 75% of the number of Registrable Securities requested to be included by the Holders were included in such registration. In the event the Company gives written notice of a Valid Business Reason, the Holders of Registrable Securities initially
requesting such Demand Registration shall be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration shall not be treated as one of the permitted Demand Registrations hereunder and the Company shall pay all
Expenses in connection with such registration. Notwithstanding the foregoing, the Company may postpone a Demand Registration hereunder only twice in any twelve-month period. 

If the Company shall give any notice of postponement, withdrawal or suspension of any registration statement pursuant to clause (iv) of
this Section 2.1(e), the Company shall not, during the period of postponement, withdrawal or suspension, register any Class A Common Stock, other than pursuant to a registration statement on Form S-4 or S-8 (or an equivalent registration form then in effect). Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company that the Company
has determined to withdraw any registration statement pursuant to clause (iv) of this Section 2.1(e), such Holder will discontinue its disposition of Registrable Securities pursuant to such registration statement and,
if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the prospectus covering such Registrable Securities that was in effect
at the time of receipt of such notice. If the Company shall have withdrawn or prematurely terminated a registration statement filed pursuant to a Demand Registration (whether pursuant to clause (iv) of this
Section 2.1(e) or as a result of any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court), the Company shall not be considered to have effected an effective registration
for the purposes of this Agreement until the Company shall have filed a new registration statement covering the Registrable Securities covered by the withdrawn registration statement and such registration statement shall have been declared

  
 8 

 
effective and shall not have been withdrawn. If the Company shall give any notice of withdrawal or postponement of a registration statement, the Company shall, not later than five Business Days
after the Valid Business Reason that caused such withdrawal or postponement no longer exists (but in no event later than 60 days after the date of the postponement or withdrawal), use its reasonable best efforts to effect the registration under the
Securities Act of the Registrable Securities covered by the withdrawn or postponed registration statement in accordance with Section 2.1 (unless the Initiating Holders shall have withdrawn such request, in which case the
Company shall not be considered to have effected an effective registration for the purposes of this Agreement), and such registration shall not be withdrawn or postponed pursuant to clause (iv) of this Section 2.1(c).

 (f) Selection of Underwriters. The Initiating Holder(s) shall have the right to select the managing underwriters for such
registration, provided that, each such managing underwriter is reasonably satisfactory to the Company, which approval shall not be unreasonably withheld or delayed. 

(g) Other Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of
Holders that hold or Beneficially Own more than 50% of the Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the
terms of which are more favorable taken as a whole than the registration rights granted to the Holders hereunder unless the Company shall also give such rights to such Holders. 

2.2. Piggyback Registrations. 

(a) Piggyback Rights. If the Company at any time proposes to file a registration statement with respect to any offering of its
securities for its own account or for the account of any Person who holds its securities (other than (i) a registration on Form S-4 or S-8 or any successor form to
such forms, (ii) a registration of securities solely relating to an offering and sale to employees, directors or consultants of the Company pursuant to any employee stock plan or other employee benefit plan arrangement, (iii) a
registration of non-convertible debt securities or (iv) an Underwritten Block Trade) (a “Piggyback Registration”) then, as expeditiously as reasonably possible (but in no event less than
ten (10) days following the date of filing such registration statement), the Company shall give written notice (the “Incidental Registration Notice”) of such proposed filing to all Holders of Registrable Securities, and such
notice shall offer the Holder the opportunity to register such number of Registrable Securities as each such Holder may request in writing. Subject to Section 2.2(c) and Section 2.2(d), the Company
shall include in such registration statement all such Registrable Securities which are requested to be included therein within fifteen (15) days after the Incidental Registration Notice is given to such Holders. 

(b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and
the Board and 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 an orderly manner in such offering within a price
range acceptable to the Company, the Company shall include, after including all of the primary securities the Company desires to include in such registration, (i) first, the number of Registrable Securities requested to be included which in the
opinion of such underwriters can be 

  
 9 

 
sold in an orderly manner within the price range acceptable to the Holder(s), pro rata among the respective Holders thereof on the basis of the number of Registrable Securities beneficially owned
by each such Holder, and (ii) second, other securities with respect to which the Company has granted registration rights in accordance with Section 2.1(g) hereof requested to be included in such registration, pro rata
among the respective Holders thereof on the basis of the amount of such securities beneficially owned by each such Holder. No employee stockholder of the Company will be entitled to include Registrable Securities in an underwritten offering
requested by the Initiating Holders pursuant to Section 2.1 to the extent that the managing underwriters and the Board of such underwritten offering shall determine in good faith that the participation of such employee
stockholder, in whole or in part, would adversely affect the marketability of the securities being sold by the Initiating Holders in such underwritten offering. 

(c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of Holders of
the Company’s securities, and the managing underwriters and the Board 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 an orderly
manner in such offering within a price range acceptable to the consent of the Majority Participating Holders to be included in such registration, the Company shall include in such registration (i) first, the securities requested to be included
therein by the Holders requesting such registration and the Registrable Securities requested to be included in such registration, pro rata among the Holders of such securities and such Registrable Securities on the basis of the number of shares
beneficially owned by each such Holder, and (ii) second, other securities with respect to which the Company has granted registration rights in accordance with Section 2.1(g) hereof requested to be included in such
registration, pro rata among the respective Holders thereof on the basis of the amount of such securities requested to be included therein by each such Holder. No Holder who is an employee stockholder of the Company will be entitled to include
Registrable Securities in an underwritten offering requested by the Initiating Holders pursuant to Section 2.1 to the extent that the managing underwriters and the Board of such underwritten offering shall determine in good
faith that the participation of such employee stockholder, in whole or in part, would adversely affect the marketability of the securities being sold by the Initiating Holders in such underwritten offering. 

(d) Selection of Underwriters. If any Piggyback Registration is an underwritten secondary offering on behalf of the Holders of the
Company’s securities, the Initiating Holder selection of investment banker(s) and manager(s) for the offering must be approved in writing by the Company. 

(e) Other Registrations. If the Company has previously filed a registration statement with respect to Registrable Securities pursuant to
Section 2.1 or pursuant to this Section 2.2, and if such previous registration has not been withdrawn or abandoned or all shares offered thereunder have been sold, the Company shall not file or
cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-8
or any successor form), whether on its own behalf or at the request of any Holder or Holders of such securities, until a period of at least 180 days has elapsed from the effective date of such previous registration. 

  
 10 

 2.3. Holdback Agreements. 

(a) Each Holder agrees not to offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any equity securities of
the Company, or any securities convertible into or exchangeable or exercisable for such securities, enter into a transaction which would have the same effect or would otherwise effect a public sale or distribution (including sales pursuant to Rule
144), or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned transaction is to be settled by delivery of such
securities or other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, in each case during the period
beginning seven days before and ending up to 180 days in connection with an initial public offering and up to 90 days in connection with a subsequent underwritten public offering, as requested by Advent or the underwriters of such initial public
offering or subsequent underwritten public offering, as applicable; provided, that no Participating Holders shall be required to agree to any lock-up restrictions to which Advent is not subject and
shall be released from any restrictions to which Advent is not subject and shall be released from any such restrictions simultaneous with and to the same extent as any other Participating Holder. In addition, each Holder of Registrable Securities
agrees to execute any further letters, agreements and/or other documents reasonably requested by the Company or its underwriters which are consistent with the terms of this Section 2.3(a). The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such restricted period. 
 (b)
The Company (i) shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such equity securities, during the period beginning seven days before and ending
180 days after the effective date of any underwritten public offering of the Company’s equity securities (including Demand and Piggyback Registrations) (except as part of such underwritten registration or pursuant to registrations on Form S-4 or S-8 or any successor form), unless the underwriters managing the registered public offering otherwise agree, and (ii) shall cause each Holder of its equity
securities, or any securities convertible into or exchangeable or exercisable for equity securities, purchased or otherwise acquired from the Company at any time after the date of this Agreement (other than in a registered public offering) to agree
not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities during any such period (except as part of such underwritten registration, if otherwise permitted), unless the underwriters managing the
registered public offering otherwise agree and such agreement permits all Holders of Registrable Securities to sell such securities on a pro rata basis. 

2.4. Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to effect or cause the
registration of any Registrable Securities under the Securities Act as provided in this Agreement, the Company shall use its reasonable best efforts to effect the registration and the widely disseminated sale of such Registrable Securities in

(l) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such

underwritten offering; 

  
 14 

 (q) promptly prior to the filing of any document which is to be incorporated by reference
into the registration statement or the prospectus (after the initial filing of such registration statement), and prior to the filing of any free writing prospectus, provide copies of such document to counsel for each Participating Holder and to each
managing underwriter, if any, and make the Company’s representatives reasonably available for discussion of such document and make such changes in such document concerning the Participating Holders prior to the filing thereof as counsel for the
Participating Holders or underwriters may reasonably request; 
 (r) furnish to counsel for each Participating Holder and to each managing

and registered in such names in accordance with the underwriting agreement at least two Business Days prior to any sale of Registrable Securities to the underwriters or, if not an underwritten offering, in accordance with the instructions of the
Participating Holders at least two Business Days prior to any sale of Registrable Securities and instruct any transfer agent and registrar of Registrable Securities to release any stop transfer orders in respect thereof; 

(t) cooperate with any due diligence investigation by any manager, underwriter or Participating Holder and make available such documents and
records of 
 (u) the Company and its Subsidiaries that they reasonably request (which, in the case of the Participating Holder, may be
subject to the execution by the Participating Holder of a customary confidentiality agreement in a form which is reasonably satisfactory to the Company); 

(v) take no direct or indirect action prohibited by Regulation M under the Exchange Act; 

(w) use its best efforts to comply with all applicable rules and regulations of the SEC, 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 thereunder; 
 (x) 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 require the
insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such Holder and its counsel should be included; 

  
 15 

 (y) in the event of the issuance of any stop order suspending the effectiveness of a
registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any of the Company’s equity securities included in such registration statement for sale in any jurisdiction,
the Company shall use its best efforts promptly to obtain the withdrawal of such order;

registration covered by Section 2.1 or Section 2.2 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, will 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; and 
 (dd) in connection with any underwritten
offering, if at any time the information conveyed to a purchaser at the time of sale includes any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, promptly file with the SEC such amendments or supplements to such information as may be necessary so that the statements as so amended or supplemented will not, in light of the circumstances,
be misleading. 
 2.5. Registration Expenses. All Expenses incurred in connection with any registration, filing, qualification or
compliance pursuant to Article 2 shall be borne by the Company, whether or not a registration statement becomes effective. All underwriting discounts and all selling commissions relating to securities registered by the Holders shall be borne by the
holders or such securities pro rata in accordance with the number of shares sold in the offering by such Participating Holder. 
 2.6. No
Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any Holder to sell any Registrable Securities pursuant to any effective registration statement. 

  
 16 

 2.7. Indemnification. 

(a) In the event of any registration and/or offering of any securities of the Company under the Securities Act pursuant to this Article 2, the
Company will, and hereby agrees to, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, fiduciaries, trustees, employees, shareholders, members or general and limited partners
(and the directors, officers, fiduciaries, employees, shareholders, members, beneficiaries or general and limited partners thereof), any underwriter (as defined in the Securities Act) for such Holder and each Person, if any, who controls such Holder
or underwriter within the meaning of the Securities Act or Exchange Act, from and against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) and expenses (including
reasonable fees of counsel and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) to which each such indemnified party may become subject under the Securities Act
or otherwise in respect thereof (collectively, “Claims”), insofar as such Claims arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any registration statement
under which such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in any preliminary or final prospectus or any amendment or supplement thereto, together with the documents incorporated by reference therein, or any free writing prospectus utilized
in connection therewith, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading, or (iii) any untrue statement or alleged untrue statement of a material fact in the information conveyed by the Company to any purchaser at the time of the sale to such purchaser, or the omission or alleged omission to state therein
a material fact required to be stated therein, or (iv) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection
with any such registration, and the Company will reimburse any such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim as such expenses are
incurred; provided, however, that the Company shall not be liable to any such indemnified party in any such case to the extent such Claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact or omission
or alleged omission of a material fact made in such registration statement or amendment thereof or supplement thereto or in any such prospectus or any preliminary or final prospectus or free writing prospectus in reliance upon and in conformity with
written information furnished to the Company by or on behalf of such indemnified party specifically for use therein. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on
behalf of such indemnified party and shall survive the transfer of such securities by such seller. 
 (b) Each Participating Holder shall,
severally and not jointly, indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) of this Section 2.7) to the extent permitted by law the Company, its officers and
directors, each Person controlling the Company within the meaning of the Securities Act, each underwriter (within the meaning of the Securities Act) of the Company’s securities covered by such a registration statement, any

  
 17 

 
Person who controls such underwriter, and any other Holder selling securities in such registration statement and each of its directors, officers, partners or agents or any Person who controls
such Holder with respect to any untrue statement or alleged untrue statement of any material fact in, or omission or alleged omission of any material fact from, such registration statement, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto, or any free writing prospectus utilized in connection therewith, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information
furnished to the Company or its representatives by or on behalf of such Participating Holder, specifically for use therein and reimburse such indemnified party for any legal or other expenses reasonably incurred in connection with investigating or
defending any such Claim as such expenses are incurred; provided, however, that the aggregate amount which any such Participating Holder shall be required to pay pursuant to this Section 2.7(b) and
Section 2.7(d) shall in no case be greater than the amount of the net proceeds actually received by such Participating Holder upon the sale of the Registrable Securities pursuant to the registration statement giving rise to
such Claim. The Company and each Participating Holder hereby acknowledge and agree that, unless otherwise expressly agreed to in writing by such Participating Holders to the contrary, for all purposes of this Agreement, the only information
furnished or to be furnished to the Company for use in any such registration statement, preliminary or final prospectus or amendment or supplement thereto or any free writing prospectus are statements specifically relating to (a) the Beneficial
Ownership of Class A Common Stock by such Participating Holder and its Affiliates and (b) the name and address of such Participating Holder. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of
any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such Holder. 
 (c) Any
Person entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this
Section 2.9, but the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 2.9, except
to the extent the indemnifying party is materially and actually prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Article 2. In case any action or
proceeding is brought against an indemnified party, the indemnifying party shall be entitled to (x) participate in such action or proceeding and (y) unless, in the reasonable opinion of outside counsel to the indemnified party, a conflict
of interest between such indemnified and indemnifying parties may exist in respect of such claim, assume the defense thereof jointly with any other indemnifying party similarly notified, with counsel reasonably satisfactory to such indemnified
party. The indemnifying party shall promptly notify the indemnified party of its decision to assume the defense of such action or proceeding. If, and after, the indemnified party has received such notice from the indemnifying party, the indemnifying
party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action or proceeding other than reasonable costs of investigation; provided,
however, that (i) if the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within 10 days after receiving notice from such indemnified party that the indemnified party believes it has
failed to do so; or (ii) if such indemnified party who is a defendant in any action or proceeding which is also brought against the indemnifying party reasonably shall have concluded that there 

  
 18 

 
may be one or more legal or equitable defenses available to such indemnified party which are not available to the indemnifying party or which may conflict with those available to another
indemnified party with respect to such Claim; or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the indemnified party shall have
the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all indemnified parties in each jurisdiction, except to the extent any indemnified party or parties reasonably shall have made a
conclusion described in clause (ii) or (iii) above) and the indemnifying party shall be liable for any expenses therefor. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of,
or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to
such action or claim), unless such settlement or compromise (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action or claim and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. The indemnity obligations contained in Section 2.7(a) and Section 2.7(b) shall
not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the indemnified party which consent shall not be unreasonably withheld. 

(d) If for any reason the foregoing indemnity is held by a court of competent jurisdiction to be unavailable to an indemnified party under
Section 2.7(a) or Section 2.7(b), then each applicable indemnifying party shall contribute to the amount paid or payable to such indemnified party as a result of any Claim in such proportion as is
appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, with respect to such Claim as well as any other relevant equitable considerations. The relative fault shall be
determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying
party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. If, however, the allocation provided in the second preceding sentence is
not permitted by applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of
the indemnifying party and the indemnified party as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if any contribution pursuant to this Section 2.7(d)
were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the preceding sentences of this Section 2.7(d). The amount paid or
payable in respect of any Claim shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim. 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 was not guilty of such fraudulent misrepresentation. Notwithstanding anything in this Section 2.7(d) to
the contrary, no indemnifying party (other than the Company) shall be required pursuant to this Section 2.7(d) to contribute any amount greater than the amount of the net proceeds actually received by such indemnifying
party upon the sale of the Registrable Securities pursuant to the registration statement giving rise to such Claim, less the amount of any indemnification payment made by such indemnifying party pursuant to Section 2.7(b).

  
 19 

 (e) The indemnity and contribution agreements contained herein shall be in addition to any
other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract (except as set forth in subsection (f) below) and shall remain operative and in full force and effect regardless of any
investigation made or omitted by or on behalf of any indemnified party and shall survive the transfer of the Registrable Securities by any such party and the completion of any offering of Registrable Securities in a registration statement. 

(f) If a customary underwriting agreement shall be entered into in connection with any registration pursuant to
Section 2.1 or Section 2.2 and certain indemnity, contribution and related provisions between the Company and the Participating Holder, the indemnity, contribution and related provisions set forth
therein shall supersede the indemnification and contribution provisions set forth in this Section 2.7. 
 2.8. Participation in
Underwritten Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s Registrable Securities on the basis provided in any underwriting arrangements
approved by the Person or Persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such
underwriting arrangements; provided, that no Holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and
warranties regarding such Holder and such Holder’s intended method of distribution) or to undertake any indemnification obligations, or provide any information, to the Company or the underwriters with respect thereto, except as otherwise
provided in Section 2.8 hereof. 
 2.9. No Inconsistent Agreements. The Company shall not hereafter enter
into any agreement with respect to its securities that is inconsistent with or violates the rights granted to the Holders in this Agreement. 

2.10. Adjustments Affecting Registrable Securities. The Company shall not take any action, or permit any change to occur, with respect
to its securities which would adversely affect the ability of the Holders of Registrable Securities to include such Registrable Securities in a registration undertaken pursuant to this Agreement or which would adversely affect the marketability of
such Registrable Securities in any such registration (including, without limitation, effecting a stock split or a combination of shares). 

Section 3. General 

3.1. Rule 144 and Rule 144A. If the Company shall have filed a registration statement pursuant to the requirements of
Section 12 of the Exchange Act or a registration statement pursuant to the requirements of the Securities Act in respect of the Class A Common Stock or Common Stock Equivalents, the Company covenants that (i) so long as it remains
subject to the reporting provisions of the Exchange Act, it will timely file the reports required to be filed by it under the Securities Act or the Exchange Act (including, but not limited to, the reports under Sections 13

  
 20 

 
and 15(d) of the Exchange Act referred to in subparagraph (c)(1)(i) of Rule 144 promulgated by the SEC under the Securities Act, as such Rule may be amended (“Rule 144”)) or, if
the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales by such Holder under Rule 144, Rule 144A promulgated by the SEC under the
Securities Act, as such Rule may be amended (“Rule 144A”), or any similar rules or regulations hereafter adopted by the SEC, and (ii) it will take such further action as any Holder may reasonably request, all to the extent
required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144, (B) Rule 144A or (C) any similar rule or
regulation hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. 

3.2. Nominees for Beneficial Owners. If Registrable Securities are held by a nominee for the Beneficial Owner thereof the Beneficial
Owner thereof may, at its option, be treated as the Holder of such Registrable Securities for purposes of any request or other action by any Holder or Holders of Registrable Securities pursuant to this Agreement (or any determination of any number
or percentage of shares constituting Registrable Securities held by any Holder or Holders of Registrable Securities contemplated by this Agreement), provided that the Company shall have received assurances reasonably satisfactory to it of
such Beneficial Ownership. 
 3.3. Amendments and Waivers. Except as otherwise provided herein, no modification, amendment or waiver
of any provision of this Agreement shall be effective against the Company or any Holder unless such modification, amendment or waiver is approved in writing by (i) the Company and (ii) the Holders holding or Beneficially Owning more than
50% of the Registrable Securities then held by all Holders; provided that any amendment, modification, supplement or waiver of any of the provisions of this Agreement which disproportionately and materially adversely affects any Holder shall
not be effective without the written approval of such Holder. For purposes of the foregoing proviso, each of Advent, Spectrum, the Krantz Holder and 22C shall be deemed to be disproportionately materially adversely affected if any right specifically
granted to any such Person herein (even if such right is granted to one or more other Holders), is amended, modified, supplemented or waived. No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any
other provision hereof (whether or not similar). No failure or delay on the part of any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof or of any other or future exercise of any such right, power or
privilege. 
 3.4. Notices. 

(a) All notices and other communications under this Agreement shall be in writing and shall be deemed given (i) when delivered personally
by hand (with written confirmation of receipt), (ii) when sent by e-mail, (iii) when received or rejected by the addressee if sent by registered or certified mail, postage prepaid, return receipt
requested, or (iv) one Business Day following the day sent by reputable overnight courier (with written confirmation of receipt), in each case at the following addresses (or to such other address as a party may have specified by notice given to

of the parties hereto, whether so expressed or not. This Agreement may not be assigned by the Company without the prior written consent of each of Advent, Spectrum, the Krantz Holder and 22C. Each Holder shall have the right to assign all or part of

all rights of the assigning Holder which are assigned to it and, to the extent such rights are assigned, any reference to the assigning Holder shall be treated as a reference to the assignee. If any Holder shall acquire additional Registrable
Securities, such Registrable Securities shall be subject to all of the terms, and entitled to all the benefits, of this Agreement.

 3.8. Interpretation; Construction. 

(a) The table of contents and headings in this Agreement are for convenience of reference only, do not constitute part of this Agreement and
shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words
“include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” 

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or

 23 

 3.10. Severability. The provisions of this Agreement shall be deemed severable
and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any person or any circumstance, is invalid or
unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of
this Agreement and the application of such provision to other persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such
provision, or the application thereof, in any other jurisdiction. 
 3.11. Remedies. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each party hereto shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, without the posting of any bond, and, if any action should be brought in equity to enforce any of the provisions of this
Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law. All remedies, either under this Agreement, by law, or otherwise afforded to any party, shall be cumulative and not alternative. 

3.12. Further Assurances. Each party hereto shall do and perform or cause to be done and performed all such further acts and
things and shall execute and deliver all such other agreements, certificates, instruments, and documents as any other party hereto reasonably may request in order to carry out the intent and accomplish the purposes of this Agreement and the
consummation of the transactions contemplated hereby. 
 3.13. Confidentiality. 

(a) Each Holder acknowledges that the provisions of this Agreement that require communications by the Company or other Holders to such Holder
may result in such Holder and its Section 3.13 Representatives acquiring material non-public information (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). 
 (b) Each Holder agrees that it will
maintain the confidentiality of such material non-public information 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 material non-public information to
(i) its directors, officers, employees, agents, attorneys, Affiliates and financial and other advisors, in each case, who reasonably need to know such information (collectively, the “Section 3.13
Representatives”), (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 and such Holder is advised by counsel that such information reasonably needs to be disclosed in connection with such
litigation; provided further, that in the case of clause (i), the recipients of such material non-public information are subject to the Policies or are directed to hold confidential the material non-public information in a manner substantially consistent with the terms of this Section 3.13. 

  
 24 

 (c) Each Holder shall have the right, at any time and from time to time (including after
receiving information regarding any potential sale or distribution to the public of Class A Common Stock of the Company pursuant to an offering registered under the Securities Act, whether by the Company, by Holders and/or by any other Holders
of the Company’s Class A Common Stock), to elect to not 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 material non-public information. 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; provided that each Holder shall use commercially reasonable efforts to minimize the administrative burden on the Company arising in connection with any such
Opt-Out Requests. 
 3.14. Termination and Effect of Termination. This Agreement shall
terminate with respect to each Holder when such Holder no longer holds any Registrable Securities and will terminate in full when no Holder holds any Registrable Securities, except for the provisions of Sections 2.7, which shall
survive any such termination. No termination under this Agreement shall relieve any Person of liability for breach or Expenses incurred prior to termination. In the event this Agreement is terminated, each Person entitled to indemnification rights
pursuant to Section 2.7 shall retain such indemnification rights with respect to any matter that (i) may be an indemnified liability thereunder and (ii) occurred prior to such termination.
