 Exhibit 4.1 

INTERMEDIA CLOUD COMMUNICATIONS, INC. 

REGISTRATION RIGHTS AGREEMENT 

THIS REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made as of [•], 2021 among Intermedia Cloud Communications,
Inc., a Delaware corporation (the “Company”), Ivy Parent Holdings, LLC (“Ivy Parent”), and each other Person who executes a Joinder as an “Other Holder” (collectively, the “Other
Holders”). Except as otherwise specified herein, all capitalized terms used in this Agreement are defined in Exhibit A attached hereto. 

In consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties to this Agreement hereby agree as follows: 
 Section 1. Demand Registrations. 

(a) Requests for Registration. At any time and from time to time, the Majority Holders may request registration under the Securities
Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration statement (“Long-Form Registrations”) or on Form
S-3 or any similar short-form registration statement (“Short-Form Registrations”), if available (any such requested registration, a “Demand Registration”). The Majority
Holders may request that any Demand Registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and (if the Company is a WKSI at the time any such request is submitted to the Company or will become
one by the time of the filing of such Shelf Registration) that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”).
Each request for a Demand Registration must specify the approximate number or dollar value of Registrable Securities requested to be registered by the requesting Holders and (if known) the intended method of distribution. The Majority Holders will
be entitled to request an unlimited number of Demand Registrations in which the Company will pay all Registration Expenses, whether or not any such registration is consummated. 

(b) Notice to Other Holders. Within four (4) days after receipt of any such request, the Company will give written notice of the
Demand Registration to all other Holders and, subject to the terms of Section 1(e), will include in such Demand Registration (and in all related registrations and qualifications under state 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 ten (10) days after the receipt of the Company’s notice; provided that, with the written consent of the Majority
Holders, the Company may, or at the written request of the Majority Holders, the Company shall, instead provide notice of the Demand Registration to all other Holders within three (3) Business Days following the
non-confidential filing of the registration statement with respect to the Demand Registration so long as such registration statement is not an Automatic Shelf Registration Statement. 

(c) Form of Registrations. All Long-Form Registrations will be underwritten registrations unless otherwise approved by the Majority
Holders. Demand Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short form unless otherwise requested by the Majority Holders. 












 (d) Shelf Registrations. 

(i) For so long as a registration statement for a Shelf Registration (a “Shelf Registration Statement”) is and remains
effective, the Majority Holders will have the right at any time or from time to time to elect to sell pursuant to an offering (including an underwritten offering) Registrable Securities available for sale pursuant to such registration statement
(“Shelf Registrable Securities”). If the Majority Holders desire to sell Registrable Securities available for sale pursuant to an underwritten offering, they shall deliver to the Company a written notice (a “Shelf Offering
Notice”) specifying the number of Shelf Registrable Securities that the holders desire to sell pursuant to such underwritten offering (the “Shelf Offering”). As promptly as practicable, but in no event later than two
(2) Business Days after receipt of a Shelf Offering Notice, the Company will give written notice of such Shelf Offering Notice to all other Holders of Shelf Registrable Securities that have been identified as selling stockholders in such Shelf
Registration Statement and are otherwise permitted to sell in such Shelf Offering. The Company, subject to Section 1(e) and Section 7, will include in such Shelf Offering all Shelf Registrable Securities with respect to which the Company
has received written requests for inclusion (which request will specify the maximum number of Shelf Registrable Securities intended to be disposed of by such Holder) within seven (7) days after the receipt of the Shelf Offering Notice. The
Company will, as expeditiously as possible (and in any event within fourteen (14) days after the receipt of a Shelf Offering Notice), but subject to Section 1(e), use its best efforts to facilitate such Shelf Offering. 

(ii) If the Majority Holders wish to engage in an underwritten block trade or bought deal off of a Shelf Registration Statement (either
through filing an Automatic Shelf Registration Statement or through a take-down from an already existing Shelf Registration Statement) (each, an “Underwritten Block Trade”), then notwithstanding the time periods set forth in
Section 1(d)(i), such Majority Holders may notify the Company of the Underwritten Block Trade not less than two (2) Business Days prior to the day such offering is first anticipated to commence. If requested by the Majority Holders, the
Company will promptly notify other Holders of such Underwritten Block Trade and such notified Holders (each, a “Potential Participant”) may elect whether or not to participate no later than the next Business Day (i.e., one
(1) Business Day prior to the day such offering is to commence) (unless a longer period is agreed to by the Majority Holders), and the Company will as expeditiously as possible use its best efforts to facilitate such Underwritten Block Trade
(which may close as early as two (2) Business Days after the date it commences); provided further that, notwithstanding the provisions of Section 1(d)(i), no Holder (other than Holders of Investor Registrable Securities) will
be permitted to participate in an Underwritten Block Trade without the written consent of the Majority Holders. Any Potential Participant’s request to participate in an Underwritten Block Trade shall be binding on the Potential Participant.

 (iii) All determinations as to whether to complete any Shelf Offering and as to the timing, manner, price and other terms of any Shelf
Offering contemplated by this Section 1(d) shall be determined by the Majority Holders, and the Company shall use its best efforts to cause any Shelf Offering to occur in accordance with such determinations as promptly as practicable. 

(iv) The Company will, at the request of the Majority Holders, file any prospectus supplement or any post-effective amendments and otherwise
take any action necessary to include therein all disclosure and language deemed necessary or advisable by the Majority Holders to effect such Shelf Offering. 

  
 2 













 (e) Priority on Demand Registrations and Shelf Offerings. The Company will not
include in any Demand Registration any securities which are not Registrable Securities without the prior written consent of the Majority Holders. If a Demand Registration or a Shelf 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, then the Company will include in such offering (prior to the inclusion of any securities which
are not Registrable Securities); (i) first, the number of Investor Registrable Securities requested to be included by any Holder which, in the opinion of such underwriters, can be sold, without any such adverse effect, to Ivy Parent; and
(ii) second, the number of Registrable Securities requested to be included by Other Holders which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective other Holders on the basis of
the number of Registrable Securities owned by each such other Holder. 
 (f) Restrictions on Demand Registration and Shelf Offerings.

 (i) The Company may postpone, for up to sixty (60) days (or with the consent of the Majority Holders, a longer period) 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 a Shelf Registration Statement (and therefore suspend
sales of the Shelf Registrable Securities) by providing written notice to the Holders if the following conditions are met: (A) the Company determines that the offer or sale of Registrable Securities would reasonably be expected to have a
material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer,
recapitalization, reorganization, financing or other transaction involving the Company and (B) upon advice of counsel, the sale of Registrable Securities pursuant to the registration statement would require disclosure of material non-public information not otherwise required to be disclosed under applicable law, and either (x) the Company has a bona fide business purpose for preserving the confidentiality of such transaction,
(y) disclosure would have a material adverse effect on the Company or the Company’s ability to consummate such transaction, or (z) such transaction renders the Company unable to comply with SEC requirements, in each case under
circumstances that would make it impractical or inadvisable to cause the registration statement (or such filings) to become effective or to promptly amend or supplement the registration statement on a post effective basis, as applicable. The Company
may delay or suspend the effectiveness of a Demand Registration or Shelf Registration Statement pursuant to this Section 1(f)(i) only once in any twelve (12)-month period (for avoidance of doubt, in addition to the Company’s rights and
obligations under Section 4(a)(vi)) unless additional delays or suspensions are approved by Ivy Parent. 

  
 3 













 (ii) In the case of an event that causes the Company to suspend the use of a Shelf
Registration Statement as set forth in paragraph (f)(ii) above or pursuant to Section 4(a)(vi) (a “Suspension Event”), the Company will give a notice to the Holders whose Registrable Securities are registered pursuant to
such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice must state generally the basis for the notice and that such suspension will continue only for so long as the
Suspension Event or its effect is continuing. Each Holder agrees not to effect any sales of its Registrable Securities pursuant to such Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the
Company and prior to receipt of an End of Suspension Notice. A Holder may recommence effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following further written notice to such effect (an
“End of Suspension Notice”) from the Company, which End of Suspension Notice will be given by the Company to the Holders promptly following the conclusion of any Suspension Event. 

(g) Selection of Underwriters. The Majority Holders will have the right to select the investment banker(s) and manager(s) to administer
any underwritten offering in connection with any Demand Registration or Shelf Offering. 
 (h) Other Registration Rights. Except as
provided in this Agreement, the Company will not grant to any Person(s) the right to request the Company or any Subsidiary to register any equity securities 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 Majority Holders. 
 (i) Revocation of Demand Notice or Shelf
Offering 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 Shelf Offering Notice, the Majority Holders may revoke or withdraw
such notice of a Demand Registration or Shelf Offering Notice on behalf of all Holders participating in such Demand Registration or Shelf Offering without liability to such Holders (including, for the avoidance of doubt, the Majority Holders), in
each case by providing written notice to the Company. 
 (j) Confidentiality. Each Holder agrees to treat as confidential the receipt
of any notice hereunder (including notice of a Demand Registration, a Shelf Offering Notice and a Suspension Notice) and the information contained therein, and not to disclose or use the information contained in any such notice (or the existence
thereof) 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). 
 Section 2. Piggyback Registrations. 

(a) Right to Piggyback. Whenever the Company proposes to register any of its equity securities under the Securities Act (including
primary and secondary registrations, and other than pursuant to an Excluded Registration) (a “Piggyback Registration”), the Company will give prompt written notice (and in any event within three (3) Business Days after the
public filing of the registration statement relating to the Piggyback Registration) to all Holders of its intention to effect such Piggyback Registration and, subject to the terms of Section 2(b) and Section 2(c), will 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
twenty (20) days after delivery 

  
 4 













 
of the Company’s notice; provided that the Company shall not be required to provide such notice or include any Registrable Securities in such registration if Ivy Parent elects not to
include any Investor Registrable Securities in such registration, unless the Majority Holders otherwise consent in writing. Any participating Majority 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) 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 will include in such registration (i) first, the
securities the Company proposes to sell, (ii) second, the Investor Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, (iii)
third, the Registrable Securities requested to be included in such registration by Other Holders which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the other Holders on the basis of the
number of Registrable Securities owned by each such other Holder, 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.

 (c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of
holders of the Company’s equity securities (other than Majority Holders), 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 will include in such registration (i) first, the securities
requested to be included therein by the holders initially requesting such registration and the Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse
effect, (ii) second, the Registrable Securities requested to be included in such registration, pro rata among the Holders on the basis of the number of Registrable Securities owned by each such Holder which, in the opinion of the
underwriters, can be sold without any such adverse effect, and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect. 

(d) Right to Terminate Registration. The Company will have the right to terminate or withdraw any registration initiated by it under
this Section 2, whether or not any holder of Registrable Securities has elected to include securities in such registration. 
 (e)
Selection of Underwriters. If any Piggyback Registration is an underwritten offering, the selection of investment banker(s) and manager(s) for the offering must be approved by the Majority Holders, which approval shall not be unreasonably
withheld, conditioned, or delayed.

 Section 3. Stockholder Lock-Up Agreements
and Company Holdback Agreement. 
 (a) Stockholder Lock-up Agreements. In connection with
any underwritten Public Offering, each Holder will enter into any lock-up, holdback or similar agreements requested by the underwriter(s) managing such offering, in each case with such modifications and
exceptions as may be approved by the Majority Holders. Without limiting the generality of the foregoing, each Holder hereby agrees that in connection with the Company’s initial Public Offering and in connection with any Demand Registration,
Shelf Offering or Piggyback Registration that is an underwritten Public Offering, not to (i) offer, sell, contract to sell, pledge or otherwise dispose of (including sales pursuant to Rule 144), directly or indirectly, any equity securities of
the Company (including equity securities of the Company that may be deemed to be owned beneficially by such Holder in accordance with the rules and regulations of the SEC) (collectively, “Securities”), or any securities, options or
rights convertible into or exchangeable or exercisable for Securities (collectively, “Other Securities”), (ii) enter into a transaction which would have the same effect as described in clause (i) above, (iii) 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 or Other Securities, whether such transaction is to be settled by delivery of such Securities or Other Securities,
in cash or otherwise (each of (i), (ii) and (iii) above, a “Sale Transaction”), or (iv) publicly disclose the intention to enter into any Sale Transaction, commencing on the date on which the Company gives notice to the
Holders that a preliminary prospectus has been circulated for such underwritten Public Offering or the “pricing” of such offering and continuing to the date that is (x) 180 days following the date of the final prospectus for such
underwritten Public Offering in the case of the Company’s initial Public Offering, or (y) 90 days following the date of the final prospectus in the case of any other such underwritten Public Offering (each such period, or such shorter period as
agreed to by the managing underwriters, a “Holdback Period”), in each case with such modifications and exceptions as may be approved by the Majority Holders. The Company may impose stop-transfer instructions with respect to any
Securities or Other Securities subject to the restrictions set forth in this Section 3(a) until the end of such Holdback Period. Notwithstanding the foregoing, no Holder (other than officers and directors of the Company) will be subject to the
Holdback Period in connection with an underwritten block Shelf Offering unless such Holder was provided notice one day prior to such underwritten block Shelf Offering and provided the opportunity to participate therein (whether or not such Holder
elects to participate in such underwritten block trade). 
 (b) Company Holdback Agreement. The Company (i) will 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 Securities or Other Securities during any Holdback Period (other than as part of such
underwritten Public Offering, or a registration on Form S-4 or Form S-8 or any successor or similar form which is (x) then in effect or (y) shall become
effective upon the conversion, exchange or exercise of any then outstanding Other Securities) and (ii) will cause each holder of Securities and Other Securities (including each of its directors and executive officers) to agree not to effect any
Sale Transaction during any Holdback Period, except as part of such underwritten registration (if otherwise permitted), unless approved in writing by the Majority Holders and the underwriters managing the Public Offering and to enter into any lock-up, holdback or similar agreements requested by the underwriter(s) managing such offering, in each case with such modifications and exceptions as may be approved by the Majority Holders.

 Section 4. Registration Procedures. 

(a) Company Obligations. Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered
pursuant to this Agreement or have initiated a Shelf Offering, the Company will use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant
thereto the Company will as expeditiously as possible: 
 (i) prepare and file with (or submit confidentially to) the SEC a registration
statement, and all amendments and supplements thereto and related prospectuses, with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, all in accordance with the Securities Act
and all applicable rules and regulations promulgated thereunder (provided that before filing or confidentially submitting a registration statement or prospectus or any amendments or supplements thereto, the Company will furnish to the counsel
selected by the Majority Holders covered by such registration statement copies of all such documents proposed to be filed or submitted, which documents will be subject to the review and comment of such counsel); 

(ii) notify each Holder of (A) the issuance by the SEC of any stop order suspending the effectiveness of any registration statement or
the initiation of any proceedings for that purpose, (B) the receipt by the Company or its counsel of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose, and (C) the effectiveness of each registration statement filed hereunder; 

(iii) prepare and file with the SEC 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) and comply with the provisions of the Securities Act with respect
to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; 

(iv) furnish, without charge, to each seller of Registrable Securities thereunder and each underwriter, if any, such number of copies of such
registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) (in each case including all exhibits and documents incorporated by reference therein), each
amendment and supplement thereto, each Free Writing Prospectus and such other documents as such seller or underwriter, if any, may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller (the
Company hereby consenting to the use in accordance with all applicable laws of each such registration statement, each such amendment and supplement thereto, and each such prospectus (or preliminary prospectus or supplement thereto) or Free Writing
Prospectus by each such seller of Registrable Securities and the underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by such registration statement or prospectus); 

  
 7 













 (v) use its best efforts to register or qualify such Registrable Securities under such other
securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of
the Registrable Securities owned by such seller (provided that the Company will 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 in writing 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 SEC 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 or of any information or circumstances 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 1(f), if required by applicable law or to the extent
requested by the Majority Holders, the Company will use its best efforts to promptly prepare and file a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus
will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading and (D) if at any time the representations and warranties of the Company in any underwriting agreement,
securities sale agreement, or other similar agreement, relating to the offering shall cease to be true and correct; 
 (vii) (A) use
best efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on a securities exchange and, without limiting the
generality of the foregoing, to arrange for at least two market markers to register as such with respect to such Registrable Securities with FINRA, and (B) comply (and continue to comply) with the requirements of any self-regulatory
organization applicable to the Company, including without limitation all corporate governance requirements; 
 (viii) use best efforts to
provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement; 

  
 8 













 (ix) enter into and perform such customary agreements (including, as applicable,
underwriting agreements in customary form) and take all such other actions as the Majority Holders or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including, without
limitation, making available the executive officers of the Company and participating in “road shows,” investor presentations, marketing events and other selling efforts and effecting a stock or unit split or combination, recapitalization
or reorganization); 
 (x) make available for inspection by any seller of Registrable Securities, any underwriter participating in any
disposition or sale 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 will be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors, employees, agents, representatives and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement and the disposition of such Registrable Securities pursuant thereto; 

(xi) take all actions to ensure that any Free-Writing Prospectus utilized in connection with any Demand Registration or Piggyback Registration
or Shelf Offering 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, prospectus supplement and related documents, 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; 
 (xii) otherwise 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 (12) 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 will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 

(xiii) permit any Holder which, 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) use best efforts to (A) make Short-Form Registration available for the sale of
Registrable Securities and (B) prevent 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 Equity included in such registration statement for sale in any jurisdiction use, and in the event any such order is issued, best efforts to obtain promptly the withdrawal of such order; 

(xv) use its 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; 

  
 9 













 (xvi) cooperate with the Holders 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, or the removal of any restrictive legends
associated with any account at which such securities are held, 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) if requested by any managing underwriter, include in any prospectus or prospectus supplement updated financial or business information
for the Company’s most recent period or current quarterly period (including estimated results or ranges of results) if required for purposes of marketing the offering in the view of the managing underwriter; 

(xviii) take no direct or indirect action prohibited by Regulation M under the Exchange Act; provided, however, that to the
extent that any prohibition is applicable to the Company, the Company will take such action as is necessary to make any such prohibition inapplicable; 

(xix) (A) cooperate with each Holder 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 the preparation and filing of applications, notices, registrations and responses to requests for additional information with FINRA, the New York Stock Exchange, Nasdaq or
any other national securities exchange on which the shares of Common Equity are or are to be listed, and (B) to the extent required by the rules and regulations of FINRA, retain a Qualified Independent Underwriter acceptable to the managing
underwriter; 
 (xx) in the case of any underwritten offering, use its best efforts to obtain, and deliver to the underwriter(s), in the
manner and to the extent provided for in the applicable underwriting agreement, one or more cold comfort letters from the Company’s independent public accountants in customary form and covering such matters of the type customarily covered by
cold comfort letters; 
 (xxi) use its best efforts to provide a legal opinion of the Company’s outside counsel, (i) dated the
effective date of such registration statement addressed to the Company addressing the validity of the Registrable Securities being offered thereby, and (ii) on the date that such Registrable Securities are delivered to the underwriters for sale
in connection with a Demand Registration or Shelf Offering, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the closing date of the applicable sale, (A) one or more
legal opinions of the Company’s outside counsel, dated such date, in form and substance as customarily given to underwriters in an underwritten public offering or, in the case of a non-underwritten
offering, to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities and (B) one or more “negative assurances letters” of the Company’s outside counsel, dated such date, in
form and substance as is customarily given to underwriters in an underwritten public offering or, in the case of a non-underwritten offering, 

  
 10 













 
to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities, in each case, addressed to the underwriters, if any, or, if requested, in the
case of a non-underwritten offering, to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities and (iii) customary certificates executed by
authorized officers of the Company as may be requested by any Holder or any underwriter of such Registrable Securities; 
 (xxii) if the
Company files an Automatic Shelf Registration Statement covering any Registrable Securities, use its best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which
such Automatic Shelf Registration Statement is required to remain effective; 
 (xxiii) 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; 

(xxiv) if the Automatic Shelf Registration Statement has been outstanding for at least three (3) 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 best efforts to refile the Shelf Registration Statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such
registration statement is required to be kept effective; and 
 (xxv) if requested by Ivy Parent, cooperate with Ivy Parent and with the
managing underwriter or agent, if any, on reasonable notice to facilitate any Charitable Gifting Event and to prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to permit any such recipient Charitable Organization to sell in the underwritten offering if it so elects. 

(b) Officer Obligations. Each Holder that is an officer of the Company agrees that if and for so long as he or she is employed by the
Company or any Subsidiary thereof, he or she will participate fully in the sale process in a manner customary for persons in like positions and consistent with his or her other duties with the Company, including the preparation of the registration
statement and the preparation and presentation of any road shows. 
 (c) Automatic Shelf Registration Statements. If the Company
files any Automatic Shelf Registration Statement for the benefit of the holders of any of its securities other than the Holders, and the Holders of Investor Registrable Securities do not request that their Registrable Securities be included in such
Shelf Registration Statement, the Company agrees that, at the request of the Majority Holders, it will include in such Automatic Shelf Registration Statement such disclosures as may be required by Rule 430B in order to ensure that the Holders of
Investor Registrable Securities may be added to such Shelf Registration Statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment. If the Company has filed any Automatic Shelf Registration
Statement for the benefit of the holders of any of its securities other than the Holders, the Company shall, at the request of the Majority Holders, file any post-effective amendments necessary to include therein all disclosure and language
necessary to ensure that the holders of Registrable Securities may be added to such Shelf Registration Statement.

Company’s obligations under the Securities Act. 
 (f) Suspended Distributions. Each Person participating in a registration
hereunder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4(a)(vi), such Person will immediately discontinue the disposition of its Registrable Securities pursuant to the

of the Company’s initial Public Offering), (vii) all applicable rating agency fees with respect to the Registrable Securities, (viii) all reasonable fees and disbursements of one legal counsel for selling Holders selected by the Majority

to the sale of Registrable Securities. 
 Section 6. Indemnification and Contribution. 

(a) By the Company. The Company will indemnify and hold harmless, to the fullest extent permitted by law and without limitation as to
time, each Holder, such Holder’s officers, directors employees, agents, fiduciaries, stockholders, managers, partners, members, affiliates, direct and indirect equityholders, consultants and representatives, and any successors and assigns
thereof, 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) (collectively, “Losses”) caused by, resulting from, arising out of, based upon or related to any of the following (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 6, 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 “blue sky” or securities laws thereof, (ii) any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or
regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In addition, the Company will reimburse such 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 will 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 

  
 13 













 
an untrue statement, or 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 will
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
or as otherwise agreed to in the underwriting agreement executed in connection with such underwritten offering. 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) By Holders. In connection with any
registration statement in which a Holder is participating, each such Holder will 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, will 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
resulting from any untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any 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 expressly for use therein; provided
that the obligation to indemnify will be individual, not joint and several, for each holder and will be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement.

 (c) Claim Procedure. Any Person entitled to indemnification hereunder will (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 will 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 will not be subject to any liability for any settlement made by the indemnified party without its consent (but
such consent will 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 will 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 will have a right to retain one separate counsel, chosen by the Majority Holders, at the expense of the indemnifying party. 

  
 14 













 (d) Contribution. If the indemnification provided for in this Section 6 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 referred to herein, then such indemnifying party will contribute to the
amounts paid or payable by such indemnified party as a result of such Loss, (i) 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 as well as any other relevant equitable considerations or (ii) if the allocation provided by clause (i) of this Section 6(d) is not permitted by applicable law,
then in such proportion as is appropriate to reflect not only such relative fault but also the relative benefit of the Company on the one hand and of the sellers of Registrable Securities and any other sellers participating in the registration
statement on the other in connection with the statement or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect of such contribution will 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 will be determined by reference to, among other things, whether the untrue (or if applicable, 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 6(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 referred to herein will 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) will be entitled to contribution from any Person who is not guilty of such fraudulent
misrepresentation. 
 (e) Release. No indemnifying party will, except with the consent of the indemnified party, consent to the entry
of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

(f) Non-exclusive Remedy; Survival. The indemnification and contribution provided for under
this Agreement will be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract (and the Company and its Subsidiaries shall be considered the indemnitors of first resort in
all such circumstances to which this Section 6 applies) and will 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 will survive the transfer of Registrable Securities and the termination or expiration of this Agreement. 

  
 15 













 Section 7. Cooperation with Underwritten Offerings. No Person may participate in
any underwritten registration hereunder 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 the terms of any over-allotment or “green shoe” option requested by the underwriters; provided that no Holder will be required to sell more than the number of Registrable Securities such
Holder has requested to include in such registration) and (ii) completes, executes and delivers all questionnaires, powers of attorney, stock powers, custody agreements, indemnities, underwriting agreements and other documents and agreements
required under the terms of such underwriting arrangements or as may be reasonably requested by the Company and the lead managing underwriter(s). To the extent that any such agreement is entered into pursuant to, and consistent with, Section 3,
Section 4 and/or this Section 7, the respective rights and obligations created under such agreement will supersede the respective rights and obligations of the Holders, the Company and the underwriters created thereby with respect to such
registration. 
 Section 8. Subsidiary Public Offering. If, after an initial Public Offering of the common equity
securities of one of its Subsidiaries, the Company distributes securities of such Subsidiary to its equityholders, then the rights and obligations of the Company pursuant to this Agreement will apply, mutatis mutandis, to such Subsidiary, and the
Company will cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement as if it were the Company hereunder. 

Section 9. Joinder; Additional Parties; Transfer of Registrable Securities. 

(a) Joinder. The Company may from time to time (with the prior written consent of the Majority Holders) permit any Person who acquires
Common Equity (or rights to acquire Common Equity) to become a party to this Agreement and to be entitled to and be bound by all of the rights and obligations as a Holder by obtaining an executed joinder to this Agreement from such Person in the
form of Exhibit B attached hereto (a “Joinder”). Upon the execution and delivery of a Joinder by such Person, the Common Equity held by such Person shall become the category of Registrable Securities (i.e. Investor or Other
Registrable Securities), and such Person shall be deemed the category of Holder (i.e. Ivy Parent or Other Holder), in each case as set forth on the signature page to such Joinder. 

(b) Restrictions on Transfers. Prior to transferring any Registrable Securities to any Person (including, without limitation, by
operation of law), the transferring Holder must first obtain the prior written consent of the Majority Holders, and if so obtained, cause the prospective transferee to execute and deliver to the Company a Joinder, except that such consent and
Joinder shall not be required in the case of (i) a transfer to the Company, (ii) a transfer by Ivy Parent to its partners or members, (iii) a Public Offering, (iv) a sale pursuant to Rule 144 after the completion of the
Company’s initial Public Offering and/or (v) a transfer in connection with a Sale of the Company. Any transfer or attempted transfer of Registrable Securities in violation of any provision of this Agreement will be void, and the Company
will not record such transfer on its books or treat any purported transferee of such Registrable Securities as the owner thereof for any purpose (but the Company will be entitled to enforce against such Person the obligations hereunder). 

(c) Legend. Each certificate (if any) 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) will be stamped or otherwise imprinted with a legend in substantially the following form: 

  
 16 













 “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 ______, 2021 AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S EQUITYHOLDERS, AS AMENDED. A COPY OF SUCH AGREEMENT WILL BE
FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.” 
 The Company will imprint such legend on
certificates evidencing Registrable Securities outstanding prior to the date hereof. The legend set forth above will be removed from the certificates evidencing any securities that have ceased to be Registrable Securities. 

Section 10. General Provisions. 

(a) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived
only with the prior written consent of the Company and the Majority Holders. The failure or delay of any Person to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will 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 will not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement. 

(b) Remedies. The parties to this Agreement will be entitled to enforce their rights under this Agreement specifically (without posting
a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that a breach of this Agreement would
cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party will be entitled to specific performance and/or other injunctive relief
from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement. 

(c) Severability. Whenever possible, each provision of this Agreement will 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 will 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 will be reformed, construed and enforced in such jurisdiction as
if such prohibited, invalid, illegal or unenforceable provision had never been contained herein. 
 (d) Entire Agreement. Except as
otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or
among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

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 of the State of Delaware or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of Delaware.

BARGAINED FOR INDUCEMENT FOR EACH OF THE PARTIES HERETO TO ENTER INTO THIS AGREEMENT (AFTER HAVING THE OPPORTUNITY TO CONSULT WITH COUNSEL), EACH PARTY HERETO EXPRESSLY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY LAWSUIT OR PROCEEDING RELATING TO OR

(k) No Recourse. Notwithstanding anything to the contrary in this Agreement, the Company and each Holder agrees and acknowledges that
no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement, will be had against any current or future director, officer, employee, general or limited partner or member of any Holder or any Affiliate

express their mutual intent, and no rule of strict construction will be applied against any party.

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 will be treated in all manner and respects as an original agreement or instrument and will 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 will re-execute original forms thereof and deliver them to all other parties. No party
hereto or to any such agreement or instrument will 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.

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.

requirements of either the Securities Act or the Exchange Act, the Company will file all reports required to be filed by it under the Securities Act and the Exchange Act and will take such further action as the Majority Holders may reasonably
request, all to the extent required to enable such Holders to sell Registrable Securities (or securities that would be Registrable Securities but for the final sentence of the definition of Registrable Securities) pursuant to Rule 144.
