nominated pursuant to this Investor Rights Agreement as and to the extent consistent with applicable Law, the Certificate of Incorporation, the Bylaws and any indemnification agreements with directors (whether such right is contained in the
Organizational Documents or another document) (except to the extent such amendment or alteration permits PubCo to provide broader indemnification or exculpation rights on a retroactive basis than permitted prior thereto). 

(h) Review of Nominees. Any nominee as a Partner Director, Sponsor Director or Joint Director (or alternate thereof)
shall be subject to PubCo’s customary due diligence process, including its review of a completed questionnaire and a background check. Based on the foregoing, PubCo may reasonably object to any such nominee within fifteen (15) days of
receiving such completed questionnaire and background check authorization, (i) provided it does so in good faith and (ii) solely to the extent such objection is based upon any of the following: (1) such nominee was convicted in a
criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses); (2) such nominee was the subject of any order, judgment or decree not subsequently reversed, suspended or vacated of

to such nominated director, the applicable Holder shall be entitled to propose a different nominee to the Board within thirty (30) days of PubCo’s notice to such Holder of its objection to such nominee and such replacement nominee shall be
subject to the review process outlined in this Section 2.1(h).

competition or any other applicable Law, each of PubCo, each of the Partners and the Sponsor agrees and acknowledges that the directors designated by the Partners and the Sponsor, may share confidential,

adequate. Accordingly, each of the Partners and the Sponsor covenants and agrees that it will not (and will cause its respective controlled Affiliates and Representatives not to) at any time, except with the prior written consent of PubCo, directly
or indirectly, disclose any Confidential Information known to it to any third party, unless (a) such information becomes known to the public through no fault of such Party, (b) disclosure is required by applicable Law (including any filing
following the Closing Date with the SEC pursuant to applicable securities Laws) or by a court of competent jurisdiction or requested by a Governmental Entity; provided, that (other than in the case of any required filing following the Closing Date

and expense of PubCo, to minimize the extent of any such required disclosure, (c) such information was available or becomes available to such Party before, on or after the Effective Date, without restriction, from a source (other than PubCo)
without any breach of duty to PubCo or (d) such information was independently developed by such Party or its Representatives without the use of the Confidential Information. Notwithstanding the foregoing, nothing in this Investor Rights
Agreement shall prohibit any of the Partners or the Sponsor from disclosing Confidential Information (x) to any Affiliate, Representative, limited partner, member or shareholder of such Party, provided, that such Person shall be bound by an
obligation of confidentiality with respect to such Confidential Information and such Party shall be responsible for any breach of this Section 2.2 by any such Person or (y) if such disclosure is made to a Governmental
Entity or regulatory authority with jurisdiction over such Party in connection with a routine audit or examination that is not specifically directed at PubCo or the Confidential Information, provided that such Party shall request that confidential
treatment be accorded to any information so disclosed. No Confidential Information shall be deemed to be provided to any Person, including any Affiliate of the Partners or the Sponsor, unless such Confidential Information is actually provided to
such Person. Furthermore, receipt of Confidential Information shall not be imputed to any Affiliate of the Partners or the Sponsor solely by virtue of the fact that the party serves in a similar capacity for such Affiliate (a “Shared
Representative”) and has received Confidential Information unless a Shared Representative (1) conveys, shares or communicates, in any manner, Confidential Information to such Affiliate or (2) participates, directly or indirectly,
on behalf of such Affiliate in activities prohibited by this Agreement.

following the Closing Date, a Shelf Registration Statement covering the resale of all Registrable Securities (except as determined by PubCo pursuant to Section 3.7 as of two (2) Business Days prior to such filing) on a
delayed or continuous basis. PubCo shall use its reasonable best efforts to cause such Shelf Registration Statement to become effective under the Securities Act as soon as practicable after such filing, but in no event later than sixty
(60) calendar days, or the earlier of (i) the 120th calendar day if the SEC notifies PubCo that it will “review” the Shelf Registration Statement or (ii) the tenth (10th)
business day after the date PubCo is notified (orally or in writing, whichever is earlier) by the SEC that such Shelf Registration Statement will not be “reviewed” or will not be subject to further review and, once effective, to keep the
Shelf Registration Statement continuously effective under the Securities Act at all times until all Registrable Securities and other securities covered by the Shelf Registration Statement have been disposed of in accordance with the intended
method(s) of distribution set forth in such Shelf Registration Statement or such securities have been withdrawn after the Closing Date. PubCo shall maintain such Shelf Registration Statement in accordance with the terms of this Investor Rights
Agreement, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep such Shelf Registration Statement continuously effective, available for use and in compliance with
the provisions of the Securities Act until such time as of which all Registrable Securities registered by such Shelf Registration Statement have been sold or cease to be Registrable Securities. In the event PubCo files a Shelf Registration Statement
on Form S-1, PubCo shall use its commercially reasonable efforts to convert such Shelf Registration Statement (and any Subsequent Shelf Registration) to a Shelf Registration Statement on Form S-3 as soon as practicable after PubCo is eligible to use Form S-3. PubCo shall also use its reasonable best efforts to file any replacement or additional Shelf Registration
Statement and use reasonable best efforts to cause such replacement or additional Shelf Registration Statement to become effective prior to the expiration of the initial Shelf Registration Statement filed pursuant to this
Section 3.1(a). 
 (b) Subsequent Shelf Registration. If any Shelf Registration Statement
ceases to be effective under the Securities Act for any reason at any time while there remain any Registrable Securities registered by such Shelf Registration Statement, PubCo shall use its reasonable best efforts to as promptly as is reasonably
practicable cause such Shelf Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its
reasonable best efforts to as promptly as is reasonably practicable amend such Shelf Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or
file an additional Registration Statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale of all outstanding Registrable Securities registered by such prior Shelf Registration Statement. If a
Subsequent Shelf 

  
 23 

 
Registration is filed, PubCo shall use its reasonable best efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably
practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an Automatic Shelf Registration Statement if PubCo is a Well-Known Seasoned Issuer) and (ii) keep such Subsequent Shelf Registration
continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as of which all Registrable Securities registered by such Subsequent Shelf Registration have been sold or cease to be Registrable
Securities. 
 (c) Suspension of Filing or Registration. If PubCo shall furnish to the Shelf Holders a certificate
signed by the chief executive officer or equivalent senior executive of PubCo, stating that the filing, effectiveness or continued use of any Shelf Registration Statement would require PubCo to make an Adverse Disclosure, then PubCo shall have a
period of not more than sixty (60) days within which to delay the filing or effectiveness (but not the preparation) of such Shelf Registration Statement or, in the case of a Shelf Registration Statement that has been declared effective, to
suspend the use by Shelf Holders of such Shelf Registration Statement (in each case, a “Shelf Suspension”); provided, however, that PubCo shall not be permitted to exercise in any twelve (12) month period (i) more than one
(1) Shelf Suspension pursuant to this Section 3.1(c) and Demand Delay pursuant to Section 3.2(a)(i) in the aggregate, unless consented to in writing by the Partners or (ii) aggregate
Shelf Suspensions pursuant to this Section 3.1(c) and Demand Delays pursuant to Section 3.2(a)(i) of more than ninety (90) days. Each Holder shall keep confidential the fact that a Shelf
Suspension is in effect, and the certificate referred to above and its contents for the permitted duration of the Shelf Suspension or until otherwise notified by PubCo, except (A) for disclosure to such Holder’s employees, agents and
professional advisers who need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such
information confidential and (C) as required by Law. In the case of a Shelf Suspension that occurs after the effectiveness of the applicable Shelf Registration Statement, the Shelf Holders agree to suspend use of the applicable Prospectus for
the permitted duration of such Shelf Suspension in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the certificate referred to above. PubCo shall immediately notify the Holders or Shelf
Holders, as applicable, upon the termination of any Shelf Suspension, and (x) in the case of a Shelf Registration Statement that has not been declared effective, shall promptly thereafter file the Shelf Registration Statement and use its
reasonable best efforts to have such Shelf Registration Statement declared effective under the Securities Act and (y) in the case of an effective Shelf Registration Statement, shall amend or supplement the Prospectus, if necessary, so it does
not contain any material misstatement or omission prior to the expiration of the Shelf Suspension and furnish to the Shelf Holders such numbers of copies of the Prospectus as so amended or supplemented as the Shelf Holders may reasonably request.
PubCo agrees, if necessary, to supplement or make amendments to the Shelf Registration Statement if required by the registration form used by PubCo for the Registration or by the instructions applicable to such registration form or by the Securities
Act or the rules or regulations promulgated thereunder or as may reasonably be requested by the Shelf Holders Beneficially Owning a majority of the Registrable Securities then outstanding.

the Underwriter or Underwriters to administer such Underwritten Shelf Take-Down; provided, that such Underwriter or Underwriters shall be reasonably acceptable to PubCo. 

(B) With respect to any Underwritten Shelf Take-Down (including any Marketed Underwritten Shelf Take-Down), in the event that
a Shelf Holder otherwise would be entitled to participate in such Underwritten Shelf Take-Down pursuant to this Section 3.1(d)(ii), Section 3.1(d)(iii) or
Section 3.1(d)(iv), as the case may be, the right of such Shelf Holder to participate in such Underwritten Shelf Take-Down shall be conditioned upon such Shelf Holder’s participation in such underwriting and the
inclusion of such Shelf Holder’s Registrable Securities in the Underwritten Offering to the extent provided herein. PubCo, together with all Shelf Holders proposing to distribute their securities through such Underwritten Shelf Take-Down, shall
enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected in accordance with Section 3.1(d)(ii)(A). Notwithstanding any other provision of this
Section 3.1, if the Underwriter shall advise PubCo that marketing factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten in
an Underwritten Shelf Take-Down, then PubCo shall so advise all Shelf Holders that have requested to participate in such Underwritten Shelf Take-Down, and the number of Registrable Securities that may be included in such Underwritten Shelf Take-Down
shall be allocated pro rata among such Shelf Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such 

  
 25 

 
Shelf Holders at the time of such Underwritten Shelf Take-Down; provided, that any Registrable Securities thereby allocated to a Shelf Holder that exceed such Shelf Holder’s request shall be
reallocated among the remaining Shelf Holders in like manner; and provided, further, that the number of Registrable Securities to be included in such Underwritten Shelf Take-Down shall not be reduced unless all other Equity Securities of PubCo are
first entirely excluded from any contemporaneous Underwritten Offering. No Registrable Securities excluded from an Underwritten Shelf Take-Down by reason of the Underwriter’s marketing limitation shall be included in such underwritten offering.

 (iii) Marketed Underwritten Shelf Take-Downs. The Shelf Take-Down Initiating Holder submitting an Underwritten
Shelf Take-Down Notice shall indicate in such notice that it delivers to PubCo pursuant to Section 3.1(d)(ii) whether it intends for such Underwritten Shelf Take-Down to be Marketed (a “Marketed Underwritten Shelf
Take-Down”). Upon receipt of an Underwritten Shelf Take-Down Notice indicating that such Underwritten Shelf Take-Down will be a Marketed Underwritten Shelf Take-Down, PubCo shall promptly (but in any event no later than ten (10) days
prior to the expected date of such Marketed Underwritten Shelf Take-Down) give written notice of such Marketed Underwritten Shelf Take-Down to all other Shelf Holders under such Shelf Registration Statement and any such Shelf Holders requesting
inclusion in such Marketed Underwritten Shelf Take-Down must respond in writing within five (5) days after the receipt of such notice. Each such Shelf Holder that timely delivers any such request shall be permitted to sell in such Marketed
Underwritten Shelf Take-Down subject to the terms and conditions of Section 3.1(d)(ii). 
 (iv) Non-Marketed Underwritten Shelf Take-Downs and Non-Underwritten Shelf Take-Downs. 

(A) Any Shelf Take-Down Initiating Holder may initiate (x) an Underwritten Shelf Take-Down that is Non-Marketed (a “Non-Marketed Underwritten Shelf Take-Down”) or (y) a Shelf Take-Down that is not an Underwritten Shelf Take-Down (a “Non-Underwritten Shelf Take-Down”) by providing written notice thereof to PubCo and, to the extent required by Section 3.1(d)(iv)(B), PubCo shall provide written notice thereof to
all other Shelf Holders. For the avoidance of doubt, a Shelf Holder that is not a Shelf Take-Down Initiating Holder cannot initiate a Shelf Take-Down. 

(B) With respect to each Restricted Shelf Take-Down, the Shelf Take-Down Initiating Holder initiating such Restricted Shelf
Take-Down shall provide written notice (a “Restricted Shelf Take-Down Notice”) of such Restricted Shelf Take-Down to PubCo and PubCo shall provide written notice thereof to all other Shelf Holders at least forty-eight
(48) hours prior to the expected time of the pricing of the applicable Restricted Shelf Take-Down, which Restricted Shelf Take-Down Notice shall set forth (I) the total number of Registrable Securities expected to be offered and sold

  
 26 

 
in such Restricted Shelf Take-Down, (II) the expected timing and plan of distribution of such Restricted Shelf Take-Down, (III) other than in the case of a Distribution (if applicable),
an invitation to each Shelf Holder to elect (such Shelf Holders who make such an election being “Take-Down Tagging Holders” and, together with the Shelf Take-Down Initiating Holders and all other Persons (other than any Affiliates
of the Shelf Take-Down Initiating Holders) who otherwise are Transferring, or have exercised a contractual or other right to Transfer, Registrable Securities in connection with such Restricted Shelf Take-Down, the “Restricted Take-Down
Selling Holders”) to include in the Restricted Shelf Take-Down Registrable Securities held by such Take-Down Tagging Holder (but subject to Section 3.1(d)(ii)(B)) and (IV) the action or actions required
(including the timing thereof) in connection with such Restricted Shelf Take-Down with respect to each Shelf Holder that elects to exercise such right (including the delivery of one or more stock certificates representing Registrable Securities of
such Shelf Holder to be sold in such Restricted Shelf Take-Down). 
 (C) Upon delivery of a Restricted Shelf Take-Down
Notice, other than in the case of a Distribution, each Shelf Holder may elect to sell Registrable Securities in such Restricted Shelf Take-Down, at the same price per Registrable Security and pursuant to the same terms and conditions with respect to
payment for the Registrable Securities as agreed to by the Shelf Take-Down Initiating Holders, by sending an irrevocable written notice (a “Take-Down Participation Notice”) to PubCo within the time period specified in such
Restricted Shelf Take-Down Notice (which time period shall be at least twenty-four (24) hours prior to the expected time of the pricing of the applicable Restricted Shelf Take-Down), indicating its, his or her election to sell up to the number
of Registrable Securities in the Restricted Shelf Take-Down specified by such Shelf Holder in such Take-Down Participation Notice (but, in all cases, subject to Section 3.1(d)(ii)(B)). Following the time period specified in
such Restricted Shelf Take-Down Notice, each Take-Down Tagging Holder that has delivered a Take-Down Participation Notice shall be permitted to sell in such Restricted Shelf Take-Down on the terms and conditions set forth in the Restricted Shelf
Take-Down Notice, concurrently with the Shelf Take-Down Initiating Holders and the other Restricted Take-Down Selling Holders, the number of Registrable Securities calculated pursuant to Section 3.1(d)(ii)(B). It is
understood that in order to be entitled to exercise its, his or her right to sell Registrable Securities in a Restricted Shelf Take-Down pursuant to this Section 3.1(d)(iv), each Take-Down Tagging Holder must agree to make
the same representations, warranties, covenants, indemnities and agreements, if any, as the Shelf Take-Down Initiating Holders agree to make in connection with the Restricted Shelf Take-Down, with such additions or changes as are required of such
Take-Down Tagging Holder by the Underwriters (if applicable). 

  
 27 

 (D) Notwithstanding the delivery of any Restricted Shelf Take-Down Notice,
all determinations as to whether to complete any Restricted Shelf Take-Down and as to the timing, manner, price and other terms and conditions of any Restricted Shelf Take-Down shall be at the sole discretion of the applicable Shelf Take-Down
Initiating Holder, and PubCo agrees to cooperate in facilitating any Restricted Shelf Take-Down pursuant to Section 3.1(d). Each of the Shelf Holders agrees to reasonably cooperate with each of the other Shelf Holders and
PubCo to establish notice, delivery and documentation procedures and measures to facilitate such other Shelf Holders’ participation in Restricted Shelf Take-Downs pursuant to this Section 3.1(d). 

Section 3.2 Demand Registrations. 

(a) Holders’ Demand for Registration. If, at a time when a Shelf Registration Statement is not effective pursuant
to Section 3.1, PubCo shall receive from the Partners at any time following the Lock-up Period (the then eligible Holders, the “Demand Initiating Holders”) a written
demand that PubCo effect any Registration in connection with an Underwritten Offering other than a Shelf Registration or a Shelf Take-Down (a “Demand Registration”) of Registrable Securities held by such Holders, PubCo will:

 (i) use its reasonable best efforts to effect such registration as soon as practicable as will permit or facilitate the
sale and distribution of all or such portion of the Demand Initiating Holders’ Registrable Securities as are specified in such demand; provided, that PubCo shall not be obligated to file any Registration Statement or other disclosure document
pursuant to this Section 3.2 (but shall be obligated to continue to prepare such Registration Statement or other disclosure document) if PubCo shall furnish to the Demand Initiating Holders a certificate signed by the chief
executive officer or equivalent senior executive of PubCo, stating that the filing or effectiveness of such Registration Statement would require PubCo to make an Adverse Disclosure, in which case PubCo shall have an additional period (each, a
“Demand Delay”) of not more than forty-five (45) days within which to file such Registration Statement; provided, however, that PubCo shall not exercise, in any twelve (12) month period, (x) more than one
(1) Demand Delay pursuant to this Section 3.2(a)(i) and Shelf Suspension pursuant to Section 3.1(c) in the aggregate, unless consented in writing by the Demand Initiating Holders or
(y) aggregate Demand Delays pursuant to this Section 3.2(a)(i) and Shelf Suspensions pursuant to Section 3.1(c) of more than ninety (90) days. Each Holder shall keep confidential the fact
that a Demand Delay is in effect, the certificate referred to above and its contents for the permitted duration of the Demand Delay or until otherwise notified by PubCo, except (A) for disclosure to the Holder’s employees, agents and
professional advisers who need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such
information confidential and (C) as required by Law. 

  
 28 

 (b) Underwriting. If the Demand Initiating Holders intend to
distribute the Registrable Securities covered by their demand by means of an Underwritten Offering, they shall so advise PubCo as part of their demand made pursuant to this Section 3.2, and PubCo shall include such
information in the written notice referred to in Section 3.2(a)(i). In such event, the right of the Demand Initiating Holders’ registration pursuant to this Section 3.2 shall be conditioned
upon the Demand Initiating Holders’ participation in such Underwritten Offering and the inclusion of the Demand Initiating Holders’ Registrable Securities in the Underwritten Offering to the extent provided herein. PubCo, together with all
holders of Registrable Securities of PubCo proposing to distribute their securities through such Underwritten Offering, shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected by the Demand
Initiating Holders that own a majority of the Registrable Securities and reasonably satisfactory to PubCo. Notwithstanding any other provision of this Section 3.2, if the Underwriter shall advise PubCo that marketing
factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten, then PubCo shall so advise the Holders that have requested to participate in such Underwritten
Offering, and the number of Registrable Securities that may be included in the Demand Registration and Underwritten Offering shall be allocated pro rata among the Demand Initiating Holders and other holders of Registrable Securities exercising a
contractual or other right to dispose of Registrable Securities in such Underwritten Offering thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such persons at the time of filing the
Registration Statement; provided, that any Registrable Securities thereby allocated to any such person that exceed such person’s request shall be reallocated among the Demand Initiating Holders and other requesting holders of Registrable
Securities in like manner; and provided, further, that the number of Registrable Securities to be included in such Underwritten Offering shall not be reduced unless all other Equity Securities of PubCo are first entirely excluded from the
Underwritten Offering. No Registrable Securities excluded from the Underwritten Offering by reason of the Underwriter’s marketing limitation shall be included in such Demand Registration. If the Underwriter has not limited the number of
Registrable Securities to be underwritten, PubCo may include securities for its own account (or for the account of any other Persons) in such Demand Registration if the Underwriter so agrees and if the number of Registrable Securities would not
thereby be limited. 
 (c) Effective Registration. PubCo shall be deemed to have effected a Demand Registration if the
Registration Statement pursuant to such registration is declared effective by the SEC and remains continuously effective for not less than one hundred eighty (180) days (or such shorter period as will terminate when all Registrable Securities
covered by such Registration Statement have been sold or withdrawn), or, if such Registration Statement relates to an Underwritten 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 sales of Registrable Securities by an Underwriter or dealer (the applicable period, the “Demand Period”). No Demand Registration shall be deemed to have been effected if (i) during the Demand Period
such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other Governmental Entity or court or (ii) the conditions specified in the underwriting agreement, if any, entered into in connection
with such Registration are not satisfied other than by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement by a participating Holder. 

  
 29 

 Section 3.3 Piggyback Registration. 

(a) If at any time or from time to time PubCo shall determine to register any of its Equity Securities, either for its own
account or for the account of security holders, including (for the avoidance of doubt) the registration of shares of Common Stock subject to PubCo’s publicly-traded warrants (other than in (1) a registration relating solely to employee
benefit plans, (2) a registration statement on Form S-4 or S-8 (or such other similar successor forms then in effect under the Securities Act), (3) a registration
pursuant to which PubCo is offering to exchange its own securities for other securities, (4) a registration statement relating solely to dividend reinvestment or similar plans, (5) a Shelf Registration Statement pursuant to which only the
initial purchasers and subsequent transferees of debt securities of PubCo or any of its subsidiaries that are convertible for Common Stock and that are initially issued pursuant to Rule 144A and/or Regulation S (or any successor provision) of the
Securities Act may resell such notes and sell the Common Stock into which such notes may be converted, (6) a registration pursuant to Section 3.1 or Section 3.2 hereof or (7) a
registration expressly contemplated by the Note Subscription Agreements), PubCo will: 
 (i) promptly (but in no event less
than ten (10) days before the effective date of the relevant Registration Statement) give to each Holder written notice thereof; and 

(ii) include in such Registration (and any related qualification under state securities Laws or other compliance), and in any
Underwritten Offering involved therein, all the Registrable Securities specified in a written request or requests made within five (5) days after receipt of such written notice from PubCo by any Holder or Holders except as set forth in
Section 3.3(b) below. 
 Notwithstanding anything herein to the contrary, this Section 3.3 shall not
apply (i) to any Shelf Take-Down irrespective of whether such Shelf Take-Down is an Underwritten Shelf Take-Down or not an Underwritten Shelf Take-Down, or (ii) following the Lock-Up Period, to any
Distribution (if applicable). 
 (b) Underwriting. If the Registration of which PubCo gives notice pursuant to
Section 3.3(a) is for an Underwritten Offering, PubCo shall so advise the Holders as a part of the written notice given pursuant to Section 3.3(a)(i). In such event the right of any Holder to
participate in such registration pursuant to this Section 3.3 shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in the
Underwritten Offering to the extent provided herein. All Holders proposing to dispose of their Registrable Securities through such Underwritten Offering, together with PubCo and the other parties distributing their Equity Securities of PubCo through
such Underwritten Offering, shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Underwritten Offering by PubCo. Notwithstanding any other provision of this
Section 3.3, if the Underwriters shall advise PubCo that marketing factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten,
then PubCo may limit the number of Registrable Securities to be included in the Registration and Underwritten Offering as follows: 

  
 30 

 (i) If the Registration is initiated and undertaken for PubCo’s
account, PubCo shall so advise all Holders of Registrable Securities that have requested to participate in such offering, and the number of Registrable Securities that may be included in the Registration and Underwritten Offering shall be allocated
in the following manner: (A) first, to PubCo, (B) second, to the Holders of Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by such Holders and (C) third, to other holders of Equity
Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities in such Underwritten Offering on a pro rata basis based on the total number of Equity Securities of PubCo held by such persons; provided, in the case of
this foregoing clause (C) that any Registrable Securities or Equity Securities thereby allocated to any such person that exceed such person’s request shall be reallocated among the remaining requesting Holders or other requesting
holders, as applicable, in like manner. 
 (ii) If the Registration is initiated and undertaken at the request of one or more
holders of Equity Securities of PubCo who are not Holders or their Affiliates, PubCo shall so advise all Holders of Registrable Securities that have requested to participate in such offering, and the number of Registrable Securities that may be
included in the Registration and Underwritten Offering shall be allocated in the following manner: (A) first, to the initiating holders of Equity Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities
in such Underwritten Offering, on a pro rata basis based on the total number of Equity Securities of PubCo, (B) second, to the Holders of Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by
such Holders, (C) third, to PubCo, (D) fourth, to other holders of Equity Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities in such Underwritten Offering on a pro rata basis based on the total
number of Equity Securities of PubCo held by such persons; provided, in the case of this foregoing clause (D) that any Registrable Securities or Equity Securities thereby allocated to any such person that exceed such person’s
request shall be reallocated among the remaining requesting Holders or other requesting holders, as applicable, in like manner. 
 No such reduction
pursuant to the foregoing paragraphs (i) and (ii) shall reduce the amount of Registrable Securities of the selling Holders included in the Registration below twenty-five percent (25%) of the total amount of Equity Securities
included in such Registration. No securities excluded from the Underwritten Offering by reason of the Underwriter’s marketing limitation shall be included in such Registration. 

  
 31 

 (c) Right to Terminate Registration. PubCo shall have the right to
terminate or withdraw any Registration initiated by it under this Section 3.3 prior to the effectiveness of such Registration whether or not any Holder has elected to include Registrable Securities in such Registration. The
expenses of such withdrawn registration shall be borne by PubCo in accordance with Section 3.4 hereof. 

Section 3.4 Expenses of Registration. All Registration Expenses incurred in connection with all Registrations or other Transfers
effected pursuant to or permitted by this Investor Rights Agreement (including any Distribution), including, all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for PubCo, shall be
borne by PubCo. It is acknowledged by the Holders that the Holders selling or otherwise Transferring any Registrable Securities in any Registration or Transfer shall bear all incremental selling expenses relating to the sale of such Registrable
Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal
counsel representing such Holders, in each case pro rata based on the number of Registrable Securities that such Holders have sold or Transferred in such Registration. 

Section 3.5 Obligations of PubCo. Whenever required under this Article III to effect the Registration of any Registrable
Securities, PubCo shall, as expeditiously as reasonably possible: 
 (a) prepare and file with the SEC a Registration
Statement with respect to such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective, and, upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days (or for such period of time specified in Section 3.1) or, if earlier, until the distribution
contemplated in the registration statement has been completed, or until all Registrable Securities covered by such Registration Statement have been sold; 

(b) prepare and file with the SEC such amendments, post-effective amendments and supplements to such Registration Statement and
the Prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by
such Registration Statement in accordance with the intended methods of disposition by sellers thereof set forth in such Registration Statement; 

(c) permit any Holder that (in the good faith reasonable judgment of the Partners) might be deemed to be a controlling person
of PubCo to participate in good faith in the preparation of such Registration Statement and to cooperate in good faith to include therein material, furnished to PubCo in writing, that in the reasonable judgment of such Holder and its counsel should
be included; 
 (d) furnish to the Holders such numbers of copies of the Registration Statement and the related Prospectus,
including all exhibits thereto and documents incorporated by reference therein and a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate
the disposition of Registrable Securities owned by them; 

  
 32 

 (e) in the event of any Underwritten Offering, enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter(s) of such offering; each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement;

 (f) notify each Holder of Registrable Securities covered by such Registration Statement as soon as reasonably possible

additional information; 
 (g) notify each Holder of Registrable Securities covered by such Registration Statement, at any
time when a Prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

(h) notify each Holder of Registrable Securities covered by such Registration Statement as soon as reasonably practicable after
notice thereof is received by PubCo of the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or any order by the SEC or any other regulatory authority preventing or suspending the use of any
preliminary or final Prospectus or the initiation or threatening of any proceedings for such purposes, or any notification with respect to the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction or
the initiation or threatening of any proceeding for such purpose; 
 (i) use its reasonable best efforts to prevent the
issuance of any stop order suspending the effectiveness of any Registration Statement or of any order preventing or suspending the use of any preliminary or final Prospectus and, if any such order is issued, to obtain the withdrawal of any such
order as soon as practicable; 
 (j) make available for inspection by each Holder including Registrable Securities in such
Registration, any Underwriter participating in any distribution pursuant to such Registration, and any attorney, accountant or other agent retained by such Holder or Underwriter, all financial and other records, pertinent corporate documents and
properties of PubCo, as such parties may reasonably request, and cause PubCo’s officers, directors and employees to supply all information reasonably requested by any such Holder, Underwriter, attorney, accountant or agent in connection with
such Registration Statement; 
 (k) use its reasonable best efforts to register or qualify, and cooperate with the Holders of
Registrable Securities covered by such Registration Statement, the Underwriters, if any, and their respective counsel, in connection with the Registration or qualification of such Registrable Securities for offer and sale under the “Blue
Sky” or securities Laws of each state and other jurisdiction of the United States as any such Holder or Underwriters, if any, or their respective counsel reasonably request in writing, and do 

  
 33 

 
any and all other things reasonably necessary or advisable to keep such Registration or qualification in effect for such period as required by Section 3.1(b) and
Section 3.2(c), as applicable; provided, that PubCo shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to taxation or
service of process in any such jurisdiction where it is not then so subject; 
 (l) in the case of an Underwritten Offering,
obtain for delivery to the Holders of Registrable Securities covered by such Registration Statement and to the Underwriters an opinion or opinions from counsel for PubCo, dated the date of the closing under the underwriting agreement, in customary

(m) in the case of an Underwritten Offering, obtain for delivery to PubCo and the Underwriters, with copies to the Holders of
Registrable Securities included in such Registration, a cold comfort letter from PubCo’s independent certified public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the
managing Underwriter or Underwriters reasonably request, dated the date of execution of the underwriting agreement and brought down to the closing under the underwriting agreement; 

(n) use its reasonable best efforts to list the Registrable Securities that are covered by such Registration Statement with any

 Section 3.6
Indemnification. 
 (a) PubCo will, and does hereby undertake to, indemnify and hold harmless each Holder of
Registrable Securities and each of such Holder’s officers, directors, trustees, employees, partners, managers, members, equityholders, beneficiaries, affiliates and agents and each Person, if any, who controls such Holder, within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect to any Registration, qualification, compliance or sale effected pursuant to this Article III, and each Underwriter, if any, and each Person who
controls any Underwriter, of the Registrable Securities held by or issuable to such Holder, against all claims, losses, damages and liabilities (or actions in respect thereto) to which they may become subject under the Securities Act, the Exchange
Act, or other federal or state Law arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular, free writing prospectus or other similar document (including
any related Registration Statement, notification, or the like) incident to any such Registration, qualification, compliance or sale effected pursuant to this Article III, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, (B) any violation or alleged violation by PubCo of any Law applicable to PubCo in
connection with any such Registration, qualification, compliance or sale, or (C) any failure to register or qualify Registrable Securities in any state where PubCo or its agents have affirmatively undertaken or agreed in writing (including
pursuant to Section 3.5(k)) that PubCo (the undertaking of any Underwriter being attributed to PubCo) will undertake such Registration or qualification on behalf of the Holders of such Registrable Securities (provided, that
in such instance PubCo shall not be so liable if it has undertaken its reasonable best efforts to so register or qualify such Registrable Securities) and will reimburse, as incurred, each such Holder, each such Underwriter and each such director,
officer, trustee, employee, partner, manager, member, equityholder, beneficiary, affiliate, agent and controlling person, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss,
damage, liability or action; provided, that PubCo will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission made in reliance and in
conformity with written information furnished to PubCo by such Holder or Underwriter expressly for use therein. 

  
 35 

 (b) Each Holder (if Registrable Securities held by or issuable to such
Holder are included in such Registration, qualification, compliance or sale pursuant to this Article III) does hereby undertake to indemnify and hold harmless, severally and not jointly, PubCo, each of its officers, directors, employees,
affiliates and agents and each Person, if any, who controls PubCo within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each Underwriter, if any, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, prospectus, offering circular, free writing prospectus or
other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, and will
reimburse, as incurred, PubCo, each of its officers, directors, employees, affiliates and agents and each Person, if any, who controls PubCo within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act,
and each Underwriter, if any, for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such
untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in such Registration Statement, prospectus, offering circular, free writing prospectus or other document, in reliance upon and in conformity with written
information that (i) relates to such Holder in its capacity as a selling security holder and (ii) was furnished to PubCo by such Holder expressly for use therein; provided, however, that the aggregate liability of each Holder hereunder
shall be limited to the net proceeds after underwriting discounts and commissions received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. It is understood and agreed that the
indemnification obligations of each Holder pursuant to any underwriting agreement entered into in connection with any Registration Statement shall be limited to the obligations contained in this Section 3.6(b). 

(c) Each party entitled to indemnification under this Section 3.6 (the “Indemnified
Party”) shall give notice to the party required to provide such indemnification (the “Indemnifying Party”) of any claim as to which indemnification may be sought promptly after such Indemnified Party has actual knowledge
thereof, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be
subject to approval by the Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at the Indemnifying Party’s expense if representation of such Indemnified Party would be
inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding; and provided, further, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations under this Section 3.6, except to the extent that such failure to give notice materially prejudices the Indemnifying Party in the defense of any
such claim or any such litigation. An 

  
 36 

 
Indemnifying Party, in the defense of any such claim or litigation, may, without the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that
(i) includes as a term thereof the giving by the claimant or plaintiff therein to such Indemnified Party of an unconditional release from all liability with respect to such claim or litigation and (ii) does not include any recovery
(including any statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Indemnified Party) other than monetary damages, and provided, that any sums payable in connection with such settlement are paid in full
by the Indemnifying Party. 
 (d) In order to provide for just and equitable contribution in case indemnification is
prohibited or limited by Law, the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of material fact or
omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and such Person’s relative intent, knowledge, access to information and opportunity to
correct or prevent such actions; provided, however, that, in any case, (i) no Holder will be required to contribute any amount in excess of the net proceeds after Underwriting discounts and commissions received by such Holder upon the sale of
the Registrable Securities giving rise to such contribution obligation and (ii) 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 was not guilty of such fraudulent misrepresentation. 
 (e) The indemnities provided in this
Section 3.6 shall survive the Transfer of any Registrable Securities by such Holder. 
 Section 3.7
Information by Holder. The Holder or Holders of Registrable Securities included in any Registration shall furnish to PubCo such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as PubCo may
reasonably request in writing and as shall be required in connection with any Registration, qualification or compliance referred to in this Article III. Each Holder agrees, if requested in writing by PubCo, to represent to PubCo the total number of
Registrable Securities held by such Holder in order for PubCo to make determinations under this Investor Rights Agreement, including for purposes of Section 3.9 hereof. Notwithstanding anything to the contrary contained in
this Investor Rights Agreement, if any Holder does not provide PubCo with information requested pursuant to this Section 3.7, PubCo may exclude such Holder’s Registrable Securities from the applicable Registration Statement or
Prospectus if PubCo determines, based on the advice of outside counsel, that such information is necessary to effect the Registration and such Holder continues thereafter to withhold such information. No Person may participate in any Underwritten
Offering of Equity Securities of PubCo pursuant to a Registration under this Investor Rights Agreement unless such Person completes and executes all customary questionnaires, powers of attorney, custody agreements,

  
 37 

 
indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting
arrangements. Subject to the minimum thresholds set forth in Section 3.1(d)(ii) and Section 3.2(a) of this Investor Rights Agreement, the exclusion of a Holder’s Registrable Securities as a result of this Section 3.7 shall
not affect the registration of the other Registrable Securities to be included in such Registration. 
 Section 3.8 Delay of
Registration. No Holder shall have any right to obtain, and hereby waives any right to seek, an injunction restraining or otherwise delaying any such Registration as the result of any controversy that might arise with respect to the
interpretation or implementation of this Article III. 
 Section 3.9 Rule 144 Reporting. With a view to making available
to the Holders the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without Registration, PubCo agrees to use its reasonable best efforts to: 

(a) make and keep current public information available, within the meaning of Rule 144 (or any similar or analogous rule)
promulgated under the Securities Act, at all times; 
 (b) file with the SEC, in a timely manner, all reports and other
documents required of PubCo under the Securities Act and Exchange Act; and 
 (c) so long as a Holder owns any Registrable
Securities, furnish to such Holder forthwith upon request a written statement by PubCo as to its compliance with the reporting requirements of said Rule 144 (at any time commencing after the Lock-Up Period),
the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of PubCo and such other reports and documents as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without Registration. 
 Section 3.10 “Market Stand Off” Agreement. 

(a) Each Holder hereby agrees that, with respect to Underwritten Offerings initiated by a Holder only, during such period
(which period shall in no event exceed ninety (90) days) following the effective date of a Registration Statement of PubCo (or, in the case of an Underwritten Shelf Take-Down, the date of the filing of a preliminary Prospectus or Prospectus
supplement relating to such Underwritten Offering (or if there is no such filing, the first contemporaneous press release announcing commencement of such Underwritten Offering)) as the Holders that own a majority of the Registrable Securities
participating in such Underwritten Offering may agree to with the Underwriter or Underwriters of such Underwritten Offering (a “Market Stand-Off Period”), such Holder or its Affiliates shall
not sell, pledge, hypothecate, transfer, make any short sale of, loan, grant any option or right to purchase of, or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any Registrable Securities held by it at any
time during such period except Registrable Securities included in such Registration and shares of Common Stock subject to a Charitable Distribution in connection with such Underwritten Offering. In connection with any Underwritten Offering
contemplated by this 

  
 38 

 
Section 3.10, PubCo shall use reasonable best efforts to cause each director and executive officer of PubCo to execute a customary
lock-up for the Market Stand-Off Period. Each Holder agrees that it shall deliver to the Underwriter or Underwriters for any such Underwritten Offering a customary
agreement (with customary terms, conditions and exceptions) that is substantially similar to the agreement delivered to the Underwriter or Underwriters by the Holders that own a majority of the Registrable Securities participating in such
Registration reflecting their agreement set forth in this Section 3.10; provided, that such agreement shall not be materially more restrictive than any similar agreement entered into by PubCo’s directors and executive
officers participating in such Underwritten Offering; provided, further, that such agreement shall not be required unless all Holders are required to enter into similar agreements; provided, further, that such agreement shall provide that any early
release of any Holder from the provisions of the terms of such agreement shall be on a pro rata basis among all Holders. 

Section 3.11 Other Obligations. In connection with a Transfer of Registrable Securities exempt from Section 5 of the
Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within the Prospectus and pursuant to the Registration Statement of which such Prospectus forms a part, PubCo shall, subject to applicable Law,
as interpreted by PubCo with the advice of counsel, and the receipt of any customary documentation required from the applicable Holders in connection therewith, (a) promptly instruct its transfer agent to remove any restrictive legends
applicable to the Registrable Securities being Transferred and (b) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under the foregoing clause (a). In
addition, PubCo shall cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with the aforementioned Transfers; provided, however, that PubCo shall have no obligation to participate in
any “road shows” or assist with the preparation of any offering memoranda or related documentation with respect to any Transfer of Registrable Securities in any transaction that does not constitute an Underwritten Offering. 

Section 3.12 Other Registration Rights. Other than the registration rights set forth in the Original RA and in the Note
Subscription Agreements, PubCo represents and warrants that no Person, other than a Holder of Registrable Securities pursuant to this Investor Rights Agreement, has any right to require PubCo to register any securities of PubCo for sale or to
include such securities of PubCo in any Registration Statement filed by PubCo for the sale of securities for its own account or for the account of any other Person. Further, each of PubCo, the Sponsor and the Financial Services Representatives
acknowledges, agrees, represents and warrants that this Investor Rights Agreement supersedes any other registration rights agreement or agreement (including the Original RA), other than the Note Subscription Agreements. 

Section 3.13 Term. Article III shall terminate with respect to any Holder on the date that such Holder no longer holds any
Registrable Securities. The provisions of Section 3.6 shall survive any such termination with respect to such Holder. 

Section 3.14 Termination of Original RA. Upon the Closing, PubCo, the Sponsor, the Original Underwriter Representatives, Brad
Weightman and Dorothy Hayes hereby agree that the Original RA and all of the respective rights and obligations of the parties thereunder are hereby terminated in their entirety and shall be of no further force or effect. 

  
 39 

 ARTICLE IV 

LOCK-UP 

Section 4.1 Lock-Up. 

(a) Each Holder (other than the Financial Services Representatives) severally, and not jointly, agrees not to effect any
Transfer, or make a public announcement of any intention to effect such Transfer, of any Lock-Up Shares (as defined below) Beneficially Owned or otherwise held by such Person during the Lock-Up Period; provided, that such prohibition shall not apply to Transfers (i) permitted pursuant to Section 4.2, or (ii) permitted pursuant to Article III. For the
avoidance of doubt, each Holder agrees not to effect a Distribution during the Lock-Up Period. The “Lock-Up Shares” means the Registrable Securities
held by the Holders (other than the Financial Services Representatives) as of the Closing Date (other than, with respect to the Sponsor and the Original Underwriter Representatives, the Private Units (as defined in the Insider Letter) and the
securities underlying the Private Units (collectively, the “Private PubCo Equity Securities”)). 
 (b)
During the Lock-Up Period, any purported Transfer of Lock-Up Shares not in accordance with this Investor Rights Agreement shall be null and void, and PubCo shall refuse
to recognize any such Transfer for any purpose. 
 (c) The Holders acknowledge and agree that, notwithstanding anything to
the contrary contained in this Investor Rights Agreement, the Lock-Up Shares Beneficially Owned by such Person shall remain subject to any restrictions on Transfer under applicable securities Laws of any
Governmental Entity, including all applicable holding periods under the Securities Act and other rules of the SEC. 
 (d)
PubCo, the Sponsor and the Original Underwriter Representatives hereby agree that the Insider Letter is hereby amended such that the provisions of Section 9 thereof shall not apply or have any further effect with respect to any Registrable
Securities other than any Private PubCo Equity Securities (and, for the avoidance of doubt, the provisions of Section 9 of the Insider Letter shall only apply to the Private PubCo Equity Securities to the extent such provisions are expressly
applicable thereto). Except as amended by this subclause (d), the provisions of the Insider Letter shall remain in full force and effect. 

Section 4.2 Permitted Transfers. Notwithstanding anything to the contrary contained in this Investor Rights Agreement, during the Lock-Up Period, the Holders may Transfer, without the consent of PubCo, any of such Person’s Lock-Up Shares to (i) any of such Person’s Permitted Transferees,
upon written notice to PubCo and, in the case of such a Transfer by the Sponsor or any of the Financial Services Representatives, the Partners, and in the case of such a Transfer by the Partners or their Permitted Transferees, the Sponsor and the
Financial Services Representatives, (ii) (a) in the case of an individual, by virtue of Laws of descent and distribution upon death of the individual; (b) in the case of an individual, pursuant to a qualified domestic relations order; or
(c) pursuant to any liquidation, merger, stock exchange or other similar transaction which results in all of PubCo’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent
to the Business Combination, 

  
 40 

 
(iii) a charitable organization through a Charitable Distribution (which for avoidance of doubt shall be deemed separate from a Transfer pursuant to clause (ii)(a) above), (iv) PubCo in
connection with the “net” or “cashless” exercise or settlement of warrants or stock options, restricted stock units or other equity awards (and any transfer to PubCo necessary to generate such amount of cash needed for the
payment of taxes, including estimated taxes, due as a result of such vesting, settlement or exercise whether by means of a “net settlement” or otherwise), or (v) PubCo in connection with the repurchase of shares of Common Stock issued
pursuant to equity awards granted under a stock incentive plan or other equity award plan or pursuant to the agreements under which such shares were issued, provided that such repurchase of shares of Common Stock is in connection with the
termination of such Holder’s service provider relationship with PubCo; provided, that in connection with any Transfer of such Lock-Up Shares pursuant to clause (ii) above, (x) the
restrictions and obligations contained in Section 4.1 and this Section 4.2 will continue to apply to such Lock-Up Shares after any Transfer of such Lock-Up Shares and such Transferee shall agree to be bound by such restrictions and obligations in writing and acknowledged by PubCo, and (y) the Transferee of such
Lock-Up Shares shall have no rights under this Investor Rights Agreement, unless, for the avoidance of doubt, such Transferee is a Permitted Transferee in accordance with this Investor Rights Agreement. Any
Transferee of Lock-Up Shares who is a Permitted Transferee of the Transferor pursuant to this Section 4.2 shall be required, at the time of and as a condition to such Transfer, to
become a party to this Investor Rights Agreement by executing and delivering a joinder in the form attached to this Investor Rights Agreement as Exhibit A, whereupon such Transferee will be treated as a Party (with the same rights and
obligations as the Transferor) for all purposes of this Investor Rights Agreement. Notwithstanding the foregoing provisions of this Section 4.2, a Holder may not make a Transfer to a Permitted Transferee if such Transfer
has as a purpose the avoidance of or is otherwise undertaken in contemplation of avoiding the restrictions on Transfers in this Agreement (it being understood that the purpose of this provision includes prohibiting the Transfer to a Permitted
Transferee (A) that has been formed to facilitate a material change with respect to who or which entities Beneficially Own the underlying Lock-Up Shares, or (B) followed by a change in the
relationship between the Holder and the Permitted Transferee (or a change of control of such Holder or Permitted Transferee) after the Transfer with the result and effect that the Holder has indirectly made a Transfer of Lock-Up Shares by using a Permitted Transferee, which Transfer would not have been directly permitted under this Article IV had such change in such relationship occurred prior to such Transfer). 

ARTICLE V 
 GENERAL
PROVISIONS 
 Section 5.1 Assignment; Successors and Assigns; No Third Party Beneficiaries. 

(a) Except as otherwise permitted pursuant to this Investor Rights Agreement, no Party may assign such Party’s rights and
obligations under this Investor Rights Agreement, in whole or in part, without the prior written consent of the Partners. Any such assignee may not again assign those rights, other than in accordance with this Article V. Any attempted
assignment of rights or obligations in violation of this Article V shall be null and void. 

  
 41 

 (b) Notwithstanding anything to the contrary contained in this Investor
Rights Agreement (other than the succeeding sentence of this Section 5.1(b)), (i) prior to the expiration of the Lock-Up Period to the extent applicable to such Holder, no Holder may
Transfer such Holder’s rights or obligations under this Investor Rights Agreement in connection with a Transfer of such Holder’s Registrable Securities, in whole or in part, except in connection with a Transfer pursuant to
Section 4.2; and (ii) after the expiration of the Lock-up Period to the extent applicable to such Holder, a Holder may Transfer such Holder’s rights or obligations under
this Investor Rights Agreement in connection with a Transfer of such Holder’s Registrable Securities, in whole or in part, to (x) any of such Holder’s Permitted Transferees (other than any charitable organization), or (y) any
Person with the prior written consent of PubCo. In no event can the Sponsor or the Partners assign any of such Person’s rights under Section 2.1. Any Transferee of Registrable Securities (other than pursuant to an
effective registration statement under the Securities Act, pursuant to a Rule 144 transaction or pursuant to any In-Kind Distribution) shall, except as otherwise expressly stated herein, have all the rights
and be subject to all of the obligations of the Transferor Holder under this Investor Rights Agreement and shall be required, at the time of and as a condition to such Transfer, to become a party to this Investor Rights Agreement by executing and
delivering a joinder in the form attached to this Investor Rights Agreement as Exhibit A. No Transfer of Registrable Securities by a Holder shall be registered on PubCo’s books and records, and such Transfer of Registrable
Securities shall be null and void and not otherwise effective, unless any such Transfer is made in accordance with the terms and conditions of this Investor Rights Agreement, and PubCo is hereby authorized by all of the Holders to enter appropriate
stop transfer notations on its transfer records to give effect to this Investor Rights Agreement. 
 (c) All of the terms and
provisions of this Investor Rights Agreement shall be binding upon the Parties and their respective successors, assigns, heirs and representatives, but shall inure to the benefit of and be enforceable by the successors, assigns, heirs and
representatives of any Party only to the extent that they are permitted successors, assigns, heirs and representatives pursuant to the terms of this Investor Rights Agreement. 

(d) Other than as expressly set forth in this Agreement, nothing in this Investor Rights Agreement, express or implied, is
intended to confer upon any Party, other than the Parties and their respective permitted successors, assigns, heirs and representatives, any rights or remedies under this Investor Rights Agreement or otherwise create any third party beneficiary
hereto. 
 Section 5.2 Termination. Except for Section 2.1(g) (which section shall terminate at such time as the
Partners, the Sponsor and their Permitted Transferees are no longer entitled to any rights pursuant to such section), Article II shall terminate automatically (without any action by any Party) as to the Partners or the Sponsor at such time at
which such Party no longer has the right to designate an individual for nomination to the Board under this Investor Rights Agreement. Except for Section 3.6 (which section shall terminate at such time as the Partners, the Sponsor, the
Financial Services Representatives and their Permitted Transferees are no longer entitled to any rights pursuant to such section), Article III of this Investor Rights Agreement shall terminate as set forth in Section 3.13. The
remainder of this Investor Rights Agreement shall terminate automatically (without any action by any Party) as to each Holder when such Holder, following 

  
 42 

 
the Closing Date, ceases to Beneficially Own any Registrable Securities; provided, that the provisions of Section 5.11, Section 5.12 and Section 5.13 shall
survive any such termination with respect to such Holder. Notwithstanding anything herein to the contrary, in the event the Merger Agreement terminates in accordance with its terms prior to the Closing, this Investor Rights Agreement shall
automatically terminate and be of no further force or effect, without any further action required by the Parties. 
 Section 5.3
Severability. If any provision of this Investor Rights Agreement is determined to be invalid, illegal or unenforceable by any Governmental Entity, the remaining provisions of this Investor Rights Agreement, to the extent permitted by Law
shall remain in full force and effect. 
 Section 5.4 Entire Agreement; Amendments; No Waiver. 

(a) This Investor Rights Agreement, as it amends and restates the Original Investor Rights Agreement, together with the Exhibit
to this Investor Rights Agreement, the Merger Agreement and all other Transaction Agreements (as such term is defined in the Merger Agreement), constitute the entire agreement among the Parties with respect to the subject matter hereof and thereof
and supersede all prior and contemporaneous agreements, understandings and discussions, whether oral or written, relating to such subject matter in any way, and there are no warranties, representations or other agreements among the Parties in
connection with such subject matter except as set forth in this Investor Rights Agreement and therein. 
 (b) No provision of
this Investor Rights Agreement may be amended or modified in whole or in part at any time without the express written consent of (i) PubCo, (ii) for so long as the Partners collectively Beneficially Own Common Stock representing 10% or more of
the Common Stock Beneficially Owned by the Partners immediately after the Closing, the Partners, and (iii) in any event, at least the Holders holding in the aggregate more than fifty percent (50%) of the Registrable Securities Beneficially
Owned by the Holders; provided, that any such amendment or modification that adversely and disproportionately affects any Holder or Holders, as compared to any other Holder or Holders, shall require the prior written consent of such Holders who
Beneficially Own a majority of the Registrable Securities Beneficially Owned by all such Holders so adversely and disproportionately affected; provided, further that any amendment or modification to Article III, Article IV,
Section 5.12, Section 5.13, Section 5.15 or this Section 5.4 that adversely affects any right granted to the Partners, the Sponsor or the
Financial Services Representatives, shall require the consent of the Partners, the Sponsor or the Financial Services Representatives, as applicable; provided, further that any amendment or modification to Article II that adversely affects any
right granted to the Partners or the Sponsor shall require the consent of the Partners or the Sponsor, as applicable; provided, further that a provision that has terminated with respect to a Party shall not require any consent of such Party (and
such Party’s Common Stock shall not be considered in computing any percentages) with respect to amending or modifying such provision. 

(c) No waiver of any provision or default under, nor consent to any exception to, the terms of this Investor Rights Agreement
shall be effective unless in writing and signed by the Party to be bound and then only to the specific purpose, extent and instance so provided. 

  
 43 

 Section 5.5 Counterparts; Electronic Delivery. This Investor Rights Agreement
and any other agreements, certificates, instruments and documents delivered pursuant to this Investor Rights Agreement may be executed and delivered in one or more counterparts and by email or other electronic transmission, each of which shall be
deemed an original and all of which shall be considered one and the same agreement. No Party shall raise the use of email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the
use of email as a defense to the formation or enforceability of a contract and each Party forever waives any such defense. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in
or relating to this Investor Rights Agreement or any document to be signed in connection with this Investor Rights Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which
shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the Parties hereto consent to conduct the
transactions contemplated hereunder by electronic means. 
 Section 5.6 Notices. All notices, demands and other communications
to be given or delivered under this Investor Rights Agreement shall be in writing and shall be deemed to have been given (a) when personally delivered (or, if delivery is refused, upon presentment) or received by email (with confirmation of
transmission) prior to 5:00 p.m. eastern time on a Business Day and, if otherwise, on the next Business Day, (b) one (1) Business Day following sending by reputable overnight express courier (charges prepaid) or (c) three (3) calendar days
following mailing by certified or registered mail, postage prepaid and return receipt requested. Unless another address is specified in writing pursuant to the provisions of this Section 5.6, notices, demands and other communications shall be
sent to the addresses indicated below:

Section 5.7 Governing Law; Waiver of Jury Trial; Jurisdiction. The Law of the State of Delaware shall govern (a) all Actions,
claims or matters related to or arising from this Investor Rights Agreement (including any tort or non-contractual claims) and (b) any questions concerning the construction, interpretation, validity and
enforceability of this Investor Rights Agreement, and the performance of the obligations imposed by this Investor Rights Agreement, in each case 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 Law of any jurisdiction other than the State of Delaware. EACH PARTY TO THIS INVESTOR RIGHTS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION
BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS INVESTOR RIGHTS AGREEMENT, THE TRANSACTIONS CONTEMPLATED BY THIS
INVESTOR RIGHTS AGREEMENT AND/OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES UNDER THIS INVESTOR RIGHTS AGREEMENT. THE PARTIES FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH SUCH PARTY’S LEGAL COUNSEL, AND THAT EACH
KNOWINGLY AND VOLUNTARILY WAIVES SUCH PARTY’S JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. Each of the Parties submits to the exclusive jurisdiction of first, the Chancery Court of the State of Delaware or if such court declines
jurisdiction, then to the Federal District Court for the District of Delaware, in any Action arising out of or relating to this Investor Rights Agreement, agrees that all claims in respect of the Action shall be heard and determined in any such
court and agrees not to bring any Action arising out of or relating to this Investor Rights Agreement in any other courts. Each Party irrevocably consents to the service of process in any such Action by the mailing of copies thereof by registered or
certified mail, postage prepaid, to such Party, at its address for notices as provided in Section 5.6 of this Investor Rights Agreement, such service to become effective ten (10) days after such mailing. Each Party hereby
irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any Action commenced hereunder or under any other documents contemplated hereby that service of process was in any way
invalid or ineffective. Nothing in this Section 5.7, however, shall affect the right of any Party to serve legal process in any other manner permitted by Law or at equity; provided, that each of the Parties hereby waives any right it may
have under the Laws of any jurisdiction to commence by publication any Action with respect to this Investor Rights Agreement. To the fullest extent permitted by applicable Law, each of the Parties hereby

  
 47 

 
irrevocably waives any objection it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Investor Rights Agreement in any of the courts referred to in
this Section 5.7 and hereby further irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such Action. Each Party agrees that a final judgment in any Action so brought
shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law or at equity, in any jurisdiction. 

Section 5.8 Specific Performance. Each Party hereby agrees and acknowledges that it will be impossible to measure in money the
damages that would be suffered if the Parties fail to comply with any of the obligations imposed on them by this Investor Rights Agreement and that, in the event of any such failure, an aggrieved Party will be irreparably damaged and will not have
an adequate remedy at Law. Any such Party shall, therefore, be entitled (in addition to any other remedy to which such Party may be entitled at Law or in equity) to seek injunctive relief, including specific performance, to enforce such obligations,
without the posting of any bond, and if any Action should be brought in equity to enforce any of the provisions of this Investor Rights Agreement, none of the Parties shall raise the defense that there is an adequate remedy at Law. 

Section 5.9 Subsequent Acquisition of Shares. Any Equity Securities of PubCo acquired subsequent to the Effective Date by a Holder
shall be subject to the terms and conditions of this Investor Rights Agreement (other than the terms and conditions of Article IV) and such shares shall be considered to be “Registrable Securities” as such term is used in this
Investor Rights Agreement. 
 Section 5.10 Consents, Approvals and Actions. If any consent, approval or action of the Partners,
the Sponsor or the Financial Services Representatives is required or permitted at any time pursuant to this Investor Rights Agreement, such consent, approval or action shall be deemed given if the holders of a majority of the outstanding Equity
Securities of PubCo held by the Partners, the Sponsor, or the Financial Services Representatives, respectively, at such time provide such consent, approval or action in writing at such time; provided that, for the avoidance of doubt, the designation
of the Joint Director pursuant to Section 2.1(a) shall require the consent of both (i) the holders of a majority of the outstanding Equity Securities of PubCo held by the Partners and (ii) the holders of a majority of the
outstanding Equity Securities of PubCo held by Sponsor. 
 Section 5.11 Not a Group; Independent Nature of Holders’ Obligations
and Rights. The Holders and PubCo agree that the arrangements contemplated by this Investor Rights Agreement are not intended to constitute the formation of a “group” (as defined in Section 13(d)(3) of the Exchange Act). Each
Holder agrees that, for purposes of determining beneficial ownership of such Holder, it shall disclaim any beneficial ownership by virtue of this Investor Rights Agreement of PubCo’s Equity Securities owned by the other Holders, and PubCo
agrees to recognize such disclaimer in its Exchange Act and Securities Act reports. The obligations of each Holder under this Investor Rights Agreement are several and not joint with the obligations of any other Holder, and no Holder shall be
responsible in any way for the performance of the obligations of any other Holder under this Investor Rights Agreement. Nothing contained herein, and no action taken by any Holder pursuant hereto, shall be deemed to constitute the Holders as, and
PubCo acknowledges that the Holders do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group or entity with
respect to such obligations or the transactions contemplated by this Investor 

  
 48 

 
Rights Agreement, and PubCo acknowledges that the Holders are not acting in concert or as a group, and PubCo shall not assert any such claim, with respect to such obligations or the transactions
contemplated by this Investor Rights Agreement. Subject to Section 5.17, the decision of each Holder to enter into this Investor Rights Agreement has been made by such Holder independently of any other Holder. Subject to
Section 5.17, each Holder acknowledges that no other Holder has acted as agent for such Holder in connection with such Holder making its investment in PubCo and that no other Holder will be acting as agent of such Holder in
connection with monitoring such Holder’s investment in the Common Stock or enforcing its rights under this Investor Rights Agreement. PubCo and each Holder confirms that each Holder has had the opportunity to independently participate with
PubCo and its subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Holder shall be entitled to independently protect and enforce its rights, including, without limitation, the
rights arising out of this Investor Rights Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement to effectuate the rights and obligations
contemplated hereby was solely in the control of PubCo, not the action or decision of any Holder, and was done solely for the convenience of PubCo and its subsidiaries and not because it was required to do so by any Holder. It is expressly
understood and agreed that each provision contained in this Investor Rights Agreement is between PubCo and a Holder, solely, and not between PubCo and the Holders collectively and not between and among the Holders. 

Section 5.12 Other Business Opportunities. 

(a) The Parties expressly acknowledge and agree that to the fullest extent permitted by applicable Law: (i) each of the
Institutional Partners, the Sponsor and the Financial Services Representatives (including (A) their respective Affiliates, (B) any portfolio company in which they or any of their respective investment fund Affiliates have made a debt or
equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the Partner Directors and the Sponsor Directors
has the right to, and shall have no duty (fiduciary, contractual or otherwise) not to, directly or indirectly engage in and possess interests in other business ventures of every type and description, including those engaged in the same or similar
business activities or lines of business as PubCo or any of its subsidiaries or deemed to be competing with PubCo or any of its subsidiaries, on its own account, or in partnership with, or as an employee, officer, director or shareholder of any
other Person, with no obligation to offer to PubCo or any of its subsidiaries, or any other Holder the right to participate therein; (ii) each of the Institutional Partners, the Sponsor and the Financial Services Representatives (including
(A) their respective Affiliates, (B) any portfolio company in which they or any of their respective investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the Partner Directors and the Sponsor Directors may invest in, or provide services to, any Person that directly or indirectly competes with
PubCo or any of its subsidiaries; and (iii) in the event that any of the Institutional Partners, the Sponsor or the Financial Services Representatives (including (A) their respective Affiliates, (B) any portfolio company in which they
or any of their respective investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing

  
 49 

 
members or other similar direct or indirect investors) or any Partner Director or Sponsor Director, respectively, acquires knowledge of a potential transaction or matter that may be a corporate
or other business opportunity for PubCo or any of its subsidiaries, such Person shall have no duty (fiduciary, contractual or otherwise) to communicate or present such corporate opportunity to PubCo or any of its subsidiaries or any other Holder, as
the case may be, and, notwithstanding any provision of this Investor Rights Agreement to the contrary, shall not be liable to PubCo or any of its subsidiaries or any other Holder (or its Affiliates) for breach of any duty (fiduciary, contractual or
otherwise) by reason of the fact that such Person, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not present such opportunity to PubCo or any of its subsidiaries or any
other Holder (or its Affiliates). For the avoidance of doubt, the Parties acknowledge that this paragraph is intended to disclaim and renounce, to the fullest extent permitted by applicable Law, any right of PubCo or any of its subsidiaries with
respect to the matters set forth herein, and this paragraph shall be construed to effect such disclaimer and renunciation to the fullest extent permitted by Law. 

(b) Each of the Parties hereby, to the fullest extent permitted by applicable Law: 

(i) confirms that none of the Institutional Partners, the Sponsor or the Financial Services Representatives or any of their
respective Affiliates have any duty to PubCo or any of its subsidiaries or to any other Holder other than the specific covenants and agreements set forth in this Investor Rights Agreement; 

(ii) acknowledges and agrees that (A) in the event of any conflict of interest between PubCo or any of its subsidiaries,
on the one hand, and any of the Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates (or any Partner Director or Sponsor Director acting in his or her capacity as such), on the other hand,
the Institutional Partners, the Sponsor, the Financial Services Representatives or applicable Affiliates (or any Partner Director or Sponsor Director acting in his or her capacity as a director) may act in its best interest and (B) none of the
Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates or any Partner Director or Sponsor Director acting in his or her capacity as a director, shall be obligated (1) to reveal to PubCo
or any of its subsidiaries confidential information belonging to or relating to the business of such Person or any of its Affiliates or (2) to recommend or take any action in its capacity as a direct or indirect stockholder or director, as the
case may be, that prefers the interest of PubCo or its subsidiaries over the interest of such Person; and 
 (iii) waives any
claim or cause of action against any of the Institutional Partners, the Sponsor, the Financial Services Representatives and any of their respective Affiliates, and any officer, employee, agent or Affiliate of any such Person that may from time to
time arise in respect of a breach by any such person of any duty or obligation disclaimed under Section 5.12(b)(i) or Section 5.12(b)(ii). 

  
 50 

 (c) Each of the Parties hereto agrees that the waivers, limitations,
acknowledgments and agreements set forth in this Section 5.12 shall not apply to any alleged claim or cause of action against any of the Institutional Partners, the Sponsor or the Financial Services Representatives based
upon the breach or nonperformance by such Person of this Investor Rights Agreement or any other agreement to which such Person is a party. 

(d) The provisions of this Section 5.12, to the extent that they restrict the duties and liabilities
of any of the Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates or any Partner Director or Sponsor Director otherwise existing at Law or in equity, are agreed by the Parties to replace
such other duties and liabilities of the Institutional Partners, the Sponsor, the Original Financial Services Representatives or any of their respective Affiliates or any such Partner Director or Sponsor Director to the fullest extent permitted by
applicable Law. 
 Section 5.13 Indemnification; Exculpation. 

(a) PubCo will, and PubCo will cause each of its subsidiaries to, jointly and severally indemnify, exonerate and hold the
Holders and each of their respective direct and indirect partners, equityholders, members, managers, Affiliates, directors, officers, shareholders, fiduciaries, managers, controlling Persons, employees, representatives and agents and each of the
partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of each of the foregoing (collectively, the “Holder Indemnitees”) free and harmless from and against
any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and out-of-pocket expenses in connection therewith (including reasonable
attorneys’ fees and expenses) incurred by the Holder Indemnitees or any of them before or after the date of this Investor Rights Agreement (collectively, the “Indemnified Liabilities”), arising out of any action, cause of
action, suit, litigation, investigation, inquiry, arbitration or claim (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) any Holder’s or its Affiliates’ ownership of Equity
Securities of PubCo or control or ability to influence PubCo or any of its subsidiaries (other than any such Indemnified Liabilities (x) to the extent such Indemnified Liabilities arise out of any breach of this Investor Rights Agreement by
such Holder Indemnitee or its Affiliates or other related Persons or the breach of any fiduciary or other duty or obligation of such Holder Indemnitee to its direct or indirect equity holders, creditors or Affiliates, (y) to the extent such
control or the ability to control PubCo or any of its subsidiaries derives from such Holder’s or its Affiliates’ capacity as an officer or director of PubCo or any of its subsidiaries or (z) to the extent such Indemnified Liabilities
are directly caused by such Person’s willful misconduct), (ii) the business, operations, properties, assets or other rights or liabilities of PubCo or any of its subsidiaries or (iii) any services provided prior to, on or after the date of
this Investor Rights Agreement by any Holder or its Affiliates to PubCo or any of their respective subsidiaries; provided, however, that if and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, PubCo
will, and will cause its subsidiaries to, make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable Law. For the purposes of this Section 5.13,
none of the circumstances described in the limitations contained in the proviso in the immediately preceding sentence shall be deemed to apply absent a final non-appealable judgment of a court of competent
jurisdiction to such effect, in which case to 

  
 51 

 
the extent any such limitation is so determined to apply to any Holder Indemnitee as to any previously advanced indemnity payments made by PubCo or any of its subsidiaries, then such payments
shall be promptly repaid by such Holder Indemnitee to PubCo and its subsidiaries. The rights of any Holder Indemnitee to indemnification hereunder will be in addition to any other rights any such Person may have under any other agreement or
instrument to which such Holder Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under Law or regulation or under the organizational or governing documents of PubCo or its subsidiaries. 

(b) PubCo will, and will cause each of its subsidiaries to, jointly and severally, reimburse any Holder Indemnitee for all
reasonable costs and expenses (including reasonable attorneys’ fees and expenses and any other litigation-related expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any
Action for which the Holder Indemnitee would be entitled to indemnification under the terms of this Section 5.13, or any action or proceeding arising therefrom, whether or not such Holder Indemnitee is a party thereto.
PubCo or its subsidiaries, in the defense of any Action for which a Holder Indemnitee would be entitled to indemnification under the terms of this Section 5.13, may, without the consent of such Holder Indemnitee, consent to
entry of any judgment or enter into any settlement if and only if it (i) includes as a term thereof the giving by the claimant or plaintiff therein to such Holder Indemnitee of an unconditional release from all liability with respect to such
Action, (ii) does not impose any limitations (equitable or otherwise) on such Holder Indemnitee, and (iii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Holder
Indemnitee, and provided, that the only penalty imposed in connection with such settlement is a monetary payment that will be paid in full by PubCo or its subsidiaries. 

(c) PubCo acknowledges and agrees that PubCo shall, and to the extent applicable shall cause its subsidiaries to, be fully and
primarily responsible for the payment to any Holder Indemnitee in respect of Indemnified Liabilities in connection with any Jointly Indemnifiable Claims (as defined below), pursuant to and in accordance with (as applicable) the terms of (i) the
Delaware General Corporation Law and the Organizational Documents, each as amended, (ii) any director indemnification agreement, (iii) this Investor Rights Agreement, any other agreement between PubCo or any of its subsidiaries and such
Holder Indemnitee (or its Affiliates) pursuant to which such Holder Indemnitee is indemnified, (iv) the Laws of the jurisdiction of incorporation or organization of any subsidiary of PubCo and/or (v) the certificate of incorporation,
certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation, certificate of limited partnership or other organizational or governing documents of any subsidiary of PubCo ((i) through
(v) collectively, the “Indemnification Sources”), irrespective of any right of recovery such Holder Indemnitee (or its Affiliates) may have from any corporation, limited liability company, partnership, joint venture, trust,
employee benefit plan or other enterprise (other than PubCo, any of its subsidiaries or the insurer under and pursuant to an insurance policy of PubCo or any of its subsidiaries) from whom such Holder Indemnitee may be entitled to indemnification
with respect to which, in whole or in part, PubCo or any of its subsidiaries may also have an indemnification obligation (collectively, the “Indemnitee-Related Entities”). Under no circumstance shall PubCo or any of its

  
 52 

 
subsidiaries be entitled to any right of subrogation or contribution by the Indemnitee-Related Entities and no right of advancement or recovery any Holder Indemnitee may have from the
Indemnitee-Related Entities shall reduce or otherwise alter the rights of such Holder Indemnitee or the obligations of PubCo or any of its subsidiaries under the Indemnification Sources. In the event that any of the Indemnitee-Related Entities shall
make any payment to any Holder Indemnitee in respect of indemnification with respect to any Jointly Indemnifiable Claim, (x) PubCo shall, and to the extent applicable shall cause its subsidiaries to, reimburse the Indemnitee-Related Entity
making such payment to the extent of such payment promptly upon written demand from such Indemnitee-Related Entity, (y) to the extent not previously and fully reimbursed by PubCo and/or any of its subsidiaries pursuant to clause (x), the
Indemnitee-Related Entity making such payment shall be subrogated to the extent of the outstanding balance of such payment to all of the rights of recovery of the Holder Indemnitee against PubCo and/or any of its subsidiaries, as applicable, and
(z) such Holder Indemnitee shall execute all papers reasonably required and shall do all things that may be reasonably necessary to secure such rights, including the execution of such documents as may be necessary to enable the
Indemnitee-Related Entities effectively to bring suit to enforce such rights. Each of the Parties agree that each of the Indemnitee-Related Entities shall be third-party beneficiaries with respect to this Section 5.13(c),
entitled to enforce this Section 5.13(c) as though each such Indemnitee-Related Entity were a party to this Investor Rights Agreement. PubCo shall cause each of its subsidiaries to perform the terms and obligations of this
Section 5.13(c) as though each such subsidiary were a party to this Investor Rights Agreement. For purposes of this Section 5.13(c), the term “Jointly Indemnifiable Claims” shall
be broadly construed and shall include, without limitation, any Indemnified Liabilities for which any Holder Indemnitee shall be entitled to indemnification from both (1) PubCo and/or any of its subsidiaries pursuant to the Indemnification
Sources, on the one hand, and (2) any Indemnitee-Related Entity pursuant to any other agreement between any Indemnitee-Related Entity and such Holder Indemnitee (or its Affiliates) pursuant to which such Holder Indemnitee is indemnified, the
Laws of the jurisdiction of incorporation or organization of any Indemnitee-Related Entity and/or the certificate of incorporation, certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation,
certificate of limited partnership or other organizational or governing documents of any Indemnitee-Related Entity, on the other hand. 

(d) In no event shall any Holder Indemnitee be liable to PubCo or any of its subsidiaries for any act, alleged act, omission or
alleged omission that does not constitute willful misconduct or fraud of such Holder Indemnitee as determined by a final, nonappealable determination of a court of competent jurisdiction. 

(e) Notwithstanding anything to the contrary contained in this Investor Rights Agreement, for purposes of this
Section 5.13, the term Holder Indemnitees shall not include any Holder or its any of its partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents or
any of the partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of any of the foregoing who is an officer or director of PubCo or any of its subsidiaries in such capacity
as officer or director. Such officers and directors are or will be subject to separate indemnification in such capacity through this Investor Rights Agreement and/or the certificate of incorporation or organization, bylaws or limited partnership
agreements and other instruments of PubCo and its subsidiaries. 

  
 53 

 (f) The rights of any Holder Indemnitee to indemnification pursuant to this
Section 5.13 will be in addition to any other rights any such Person may have under any other section of this Investor Rights Agreement or any other agreement or instrument to which such Holder Indemnitee is or becomes a
party or is or otherwise becomes a beneficiary or under Law or regulation or under the certificate of limited partnership, limited partnership agreement, certificate of incorporation or bylaws (or equivalent governing documents) of PubCo or any of
its subsidiaries.

subsequently reversed, suspended or vacated; or (5) such nominee was the subject of, or a party to, any federal or state judicial or administrative order, judgment, decree or finding, not subsequently reversed, suspended or vacated, relating to
a violation of any federal or state securities Laws or regulations. In the event the Board reasonably finds any such nominee to be unsuitable based upon one or more of the foregoing clauses (1) through (5) and reasonably objects
to such nominated director, the applicable Holder shall be entitled to propose a different nominee to the Board within thirty (30) days of PubCo’s notice to such Holder of its objection to such nominee and such replacement nominee shall be
subject to the review process outlined in this Section 2.1(h). 
  

  
 13 

 Section 2.2 Sharing of Information. To the extent permitted by antitrust,
competition or any other applicable Law, each of PubCo, each of the Partners and the Sponsor agrees and acknowledges that the directors designated by the Partners and the Sponsor, may share confidential,
non-public information about PubCo and its subsidiaries (“Confidential Information”) with the Partners and the Sponsor, as applicable. Each of the Partners and the Sponsor recognizes that it,
or its Affiliates and Representatives, has acquired or will acquire Confidential Information the use or disclosure of which could cause PubCo substantial loss and damages that could not be readily calculated and for which no remedy at Law would be
adequate. Accordingly, each of the Partners and the Sponsor covenants and agrees that it will not (and will cause its respective controlled Affiliates and Representatives not to) at any time, except with the prior written consent of PubCo, directly
or indirectly, disclose any Confidential Information known to it to any third party, unless (a) such information becomes known to the public through no fault of such Party, (b) disclosure is required by applicable Law (including any filing
following the Closing Date with the SEC pursuant to applicable securities Laws) or by a court of competent jurisdiction or requested by a Governmental Entity; provided, that (other than in the case of any required filing following the Closing Date
with the SEC or in connection with any routine audit or examination as described below) such Party (to the extent legally permissible) promptly notifies PubCo of such requirement or request and takes commercially reasonable steps, at the sole cost
and expense of PubCo, to minimize the extent of any such required disclosure, (c) such information was available or becomes available to such Party before, on or after the Effective Date, without restriction, from a source (other than PubCo)
without any breach of duty to PubCo or (d) such information was independently developed by such Party or its Representatives without the use of the Confidential Information. Notwithstanding the foregoing, nothing in this Investor Rights
Agreement shall prohibit any of the Partners or the Sponsor from disclosing Confidential Information (x) to any Affiliate, Representative, limited partner, member or shareholder of such Party, provided, that such Person shall be bound by an
obligation of confidentiality with respect to such Confidential Information and such Party shall be responsible for any breach of this Section 2.2 by any such Person or (y) if such disclosure is made to a Governmental
Entity or regulatory authority with jurisdiction over such Party in connection with a routine audit or examination that is not specifically directed at PubCo or the Confidential Information, provided that such Party shall request that confidential
treatment be accorded to any information so disclosed. No Confidential Information shall be deemed to be provided to any Person, including any Affiliate of the Partners or the Sponsor, unless such Confidential Information is actually provided to
such Person. Furthermore, receipt of Confidential Information shall not be imputed to any Affiliate of the Partners or the Sponsor solely by virtue of the fact that the party serves in a similar capacity for such Affiliate (a “Shared
Representative”) and has received Confidential Information unless a Shared Representative (1) conveys, shares or communicates, in any manner, Confidential Information to such Affiliate or (2) participates, directly or indirectly,
on behalf of such Affiliate in activities prohibited by this Agreement.

 ARTICLE III 

REGISTRATION RIGHTS 

Section 3.1 Shelf Registration. 

(a) Filing. PubCo shall file, as soon as is reasonably practicable and in any event within forty-five (45) days
following the Closing Date, a Shelf Registration Statement covering the resale of all Registrable Securities (except as determined by PubCo pursuant to Section 3.7 as of two (2) Business Days prior to such filing) on a
delayed or continuous basis. PubCo shall use its reasonable best efforts to cause such Shelf Registration Statement to become effective under the Securities Act as soon as practicable after such filing, but in no event later than sixty
(60) calendar days, or the earlier of (i) the 120th calendar day if the SEC notifies PubCo that it will “review” the Shelf Registration Statement or (ii) the tenth (10th)
business day after the date PubCo is notified (orally or in writing, whichever is earlier) by the SEC that such Shelf Registration Statement will not be “reviewed” or will not be subject to further review and, once effective, to keep the
Shelf Registration Statement continuously effective under the Securities Act at all times until all Registrable Securities and other securities covered by the Shelf Registration Statement have been disposed of in accordance with the intended
method(s) of distribution set forth in such Shelf Registration Statement or such securities have been withdrawn after the Closing Date. PubCo shall maintain such Shelf Registration Statement in accordance with the terms of this Investor Rights
Agreement, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep such Shelf Registration Statement continuously effective, available for use and in compliance with
the provisions of the Securities Act until such time as of which all Registrable Securities registered by such Shelf Registration Statement have been sold or cease to be Registrable Securities. In the event PubCo files a Shelf Registration Statement
on Form S-1, PubCo shall use its commercially reasonable efforts to convert such Shelf Registration Statement (and any Subsequent Shelf Registration) to a Shelf Registration Statement on Form S-3 as soon as practicable after PubCo is eligible to use Form S-3. PubCo shall also use its reasonable best efforts to file any replacement or additional Shelf Registration
Statement and use reasonable best efforts to cause such replacement or additional Shelf Registration Statement to become effective prior to the expiration of the initial Shelf Registration Statement filed pursuant to this
Section 3.1(a). 
 (b) Subsequent Shelf Registration. If any Shelf Registration Statement
ceases to be effective under the Securities Act for any reason at any time while there remain any Registrable Securities registered by such Shelf Registration Statement, PubCo shall use its reasonable best efforts to as promptly as is reasonably
practicable cause such Shelf Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its
reasonable best efforts to as promptly as is reasonably practicable amend such Shelf Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or
file an additional Registration Statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale of all outstanding Registrable Securities registered by such prior Shelf Registration Statement. If a
Subsequent Shelf 

  
 15 

 
Registration is filed, PubCo shall use its reasonable best efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably
practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an Automatic Shelf Registration Statement if PubCo is a Well-Known Seasoned Issuer) and (ii) keep such Subsequent Shelf Registration
continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as of which all Registrable Securities registered by such Subsequent Shelf Registration have been sold or cease to be Registrable
Securities. 
 (c) Suspension of Filing or Registration. If PubCo shall furnish to the Shelf Holders a certificate
signed by the chief executive officer or equivalent senior executive of PubCo, stating that the filing, effectiveness or continued use of any Shelf Registration Statement would require PubCo to make an Adverse Disclosure, then PubCo shall have a
period of not more than sixty (60) days within which to delay the filing or effectiveness (but not the preparation) of such Shelf Registration Statement or, in the case of a Shelf Registration Statement that has been declared effective, to
suspend the use by Shelf Holders of such Shelf Registration Statement (in each case, a “Shelf Suspension”); provided, however, that PubCo shall not be permitted to exercise in any twelve (12) month period (i) more than one
(1) Shelf Suspension pursuant to this Section 3.1(c) and Demand Delay pursuant to Section 3.2(a)(i) in the aggregate, unless consented to in writing by the Partners or (ii) aggregate
Shelf Suspensions pursuant to this Section 3.1(c) and Demand Delays pursuant to Section 3.2(a)(i) of more than ninety (90) days. Each Holder shall keep confidential the fact that a Shelf
Suspension is in effect, and the certificate referred to above and its contents for the permitted duration of the Shelf Suspension or until otherwise notified by PubCo, except (A) for disclosure to such Holder’s employees, agents and
professional advisers who need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such
information confidential and (C) as required by Law. In the case of a Shelf Suspension that occurs after the effectiveness of the applicable Shelf Registration Statement, the Shelf Holders agree to suspend use of the applicable Prospectus for
the permitted duration of such Shelf Suspension in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the certificate referred to above. PubCo shall immediately notify the Holders or Shelf
Holders, as applicable, upon the termination of any Shelf Suspension, and (x) in the case of a Shelf Registration Statement that has not been declared effective, shall promptly thereafter file the Shelf Registration Statement and use its
reasonable best efforts to have such Shelf Registration Statement declared effective under the Securities Act and (y) in the case of an effective Shelf Registration Statement, shall amend or supplement the Prospectus, if necessary, so it does
not contain any material misstatement or omission prior to the expiration of the Shelf Suspension and furnish to the Shelf Holders such numbers of copies of the Prospectus as so amended or supplemented as the Shelf Holders may reasonably request.
PubCo agrees, if necessary, to supplement or make amendments to the Shelf Registration Statement if required by the registration form used by PubCo for the Registration or by the instructions applicable to such registration form or by the Securities
Act or the rules or regulations promulgated thereunder or as may reasonably be requested by the Shelf Holders Beneficially Owning a majority of the Registrable Securities then outstanding. 

  
 16 

 (d) Shelf Take-Downs. 

(i) Generally. Subject to the terms and provisions of this Article III, following the Lock-Up Period, a Shelf Take-Down Initiating Holder may initiate a Shelf Take-Down that, at the option of such Shelf Take-Down Initiating Holder (A) is in the form of an Underwritten Shelf Take-Down or a Shelf
Take-Down that is not an Underwritten Shelf Take-Down and (B) in the case of an Underwritten Shelf Take-Down, is Non-Marketed or Marketed, in each case, as shall be specified in the written demand
delivered by the Shelf Take-Down Initiating Holder to PubCo pursuant to the provisions of this Section 3.1(d). 

(ii) Underwritten Shelf Take-Downs. 

(A) A Shelf Take-Down Initiating Holder may elect in a written demand delivered to PubCo (an “Underwritten Shelf
Take-Down Notice”) for any Shelf Take-Down that it has initiated to be in the form of an underwritten offering (an “Underwritten Shelf Take-Down”), and PubCo shall, if so requested, file and effect an amendment or
supplement of the Shelf Registration Statement for such purpose as soon as practicable. The Shelf Holders that own a majority of the Registrable Securities to be offered for sale in such Underwritten Shelf Take-Down shall have the right to select
the Underwriter or Underwriters to administer such Underwritten Shelf Take-Down; provided, that such Underwriter or Underwriters shall be reasonably acceptable to PubCo. 

(B) With respect to any Underwritten Shelf Take-Down (including any Marketed Underwritten Shelf Take-Down), in the event that
a Shelf Holder otherwise would be entitled to participate in such Underwritten Shelf Take-Down pursuant to this Section 3.1(d)(ii), Section 3.1(d)(iii) or
Section 3.1(d)(iv), as the case may be, the right of such Shelf Holder to participate in such Underwritten Shelf Take-Down shall be conditioned upon such Shelf Holder’s participation in such underwriting and the
inclusion of such Shelf Holder’s Registrable Securities in the Underwritten Offering to the extent provided herein. PubCo, together with all Shelf Holders proposing to distribute their securities through such Underwritten Shelf Take-Down, shall
enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected in accordance with Section 3.1(d)(ii)(A). Notwithstanding any other provision of this
Section 3.1, if the Underwriter shall advise PubCo that marketing factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten in
an Underwritten Shelf Take-Down, then PubCo shall so advise all Shelf Holders that have requested to participate in such Underwritten Shelf Take-Down, and the number of Registrable Securities that may be included in such Underwritten Shelf Take-Down
shall be allocated pro rata among such Shelf Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such 

  
 17 

 
Shelf Holders at the time of such Underwritten Shelf Take-Down; provided, that any Registrable Securities thereby allocated to a Shelf Holder that exceed such Shelf Holder’s request shall be
reallocated among the remaining Shelf Holders in like manner; and provided, further, that the number of Registrable Securities to be included in such Underwritten Shelf Take-Down shall not be reduced unless all other Equity Securities of PubCo are
first entirely excluded from any contemporaneous Underwritten Offering. No Registrable Securities excluded from an Underwritten Shelf Take-Down by reason of the Underwriter’s marketing limitation shall be included in such underwritten offering.

 (iii) Marketed Underwritten Shelf Take-Downs. The Shelf Take-Down Initiating Holder submitting an Underwritten
Shelf Take-Down Notice shall indicate in such notice that it delivers to PubCo pursuant to Section 3.1(d)(ii) whether it intends for such Underwritten Shelf Take-Down to be Marketed (a “Marketed Underwritten Shelf
Take-Down”). Upon receipt of an Underwritten Shelf Take-Down Notice indicating that such Underwritten Shelf Take-Down will be a Marketed Underwritten Shelf Take-Down, PubCo shall promptly (but in any event no later than ten (10) days
prior to the expected date of such Marketed Underwritten Shelf Take-Down) give written notice of such Marketed Underwritten Shelf Take-Down to all other Shelf Holders under such Shelf Registration Statement and any such Shelf Holders requesting
inclusion in such Marketed Underwritten Shelf Take-Down must respond in writing within five (5) days after the receipt of such notice. Each such Shelf Holder that timely delivers any such request shall be permitted to sell in such Marketed
Underwritten Shelf Take-Down subject to the terms and conditions of Section 3.1(d)(ii). 
 (iv) Non-Marketed Underwritten Shelf Take-Downs and Non-Underwritten Shelf Take-Downs. 

(A) Any Shelf Take-Down Initiating Holder may initiate (x) an Underwritten Shelf Take-Down that is Non-Marketed (a “Non-Marketed Underwritten Shelf Take-Down”) or (y) a Shelf Take-Down that is not an Underwritten Shelf Take-Down (a “Non-Underwritten Shelf Take-Down”) by providing written notice thereof to PubCo and, to the extent required by Section 3.1(d)(iv)(B), PubCo shall provide written notice thereof to
all other Shelf Holders. For the avoidance of doubt, a Shelf Holder that is not a Shelf Take-Down Initiating Holder cannot initiate a Shelf Take-Down. 

(B) With respect to each Restricted Shelf Take-Down, the Shelf Take-Down Initiating Holder initiating such Restricted Shelf
Take-Down shall provide written notice (a “Restricted Shelf Take-Down Notice”) of such Restricted Shelf Take-Down to PubCo and PubCo shall provide written notice thereof to all other Shelf Holders at least forty-eight
(48) hours prior to the expected time of the pricing of the applicable Restricted Shelf Take-Down, which Restricted Shelf Take-Down Notice shall set forth (I) the total number of Registrable Securities expected to be offered and sold

  
 18 

 
in such Restricted Shelf Take-Down, (II) the expected timing and plan of distribution of such Restricted Shelf Take-Down, (III) other than in the case of a Distribution (if applicable),
an invitation to each Shelf Holder to elect (such Shelf Holders who make such an election being “Take-Down Tagging Holders” and, together with the Shelf Take-Down Initiating Holders and all other Persons (other than any Affiliates
of the Shelf Take-Down Initiating Holders) who otherwise are Transferring, or have exercised a contractual or other right to Transfer, Registrable Securities in connection with such Restricted Shelf Take-Down, the “Restricted Take-Down
Selling Holders”) to include in the Restricted Shelf Take-Down Registrable Securities held by such Take-Down Tagging Holder (but subject to Section 3.1(d)(ii)(B)) and (IV) the action or actions required
(including the timing thereof) in connection with such Restricted Shelf Take-Down with respect to each Shelf Holder that elects to exercise such right (including the delivery of one or more stock certificates representing Registrable Securities of
such Shelf Holder to be sold in such Restricted Shelf Take-Down). 
 (C) Upon delivery of a Restricted Shelf Take-Down
Notice, other than in the case of a Distribution, each Shelf Holder may elect to sell Registrable Securities in such Restricted Shelf Take-Down, at the same price per Registrable Security and pursuant to the same terms and conditions with respect to
payment for the Registrable Securities as agreed to by the Shelf Take-Down Initiating Holders, by sending an irrevocable written notice (a “Take-Down Participation Notice”) to PubCo within the time period specified in such
Restricted Shelf Take-Down Notice (which time period shall be at least twenty-four (24) hours prior to the expected time of the pricing of the applicable Restricted Shelf Take-Down), indicating its, his or her election to sell up to the number
of Registrable Securities in the Restricted Shelf Take-Down specified by such Shelf Holder in such Take-Down Participation Notice (but, in all cases, subject to Section 3.1(d)(ii)(B)). Following the time period specified in
such Restricted Shelf Take-Down Notice, each Take-Down Tagging Holder that has delivered a Take-Down Participation Notice shall be permitted to sell in such Restricted Shelf Take-Down on the terms and conditions set forth in the Restricted Shelf
Take-Down Notice, concurrently with the Shelf Take-Down Initiating Holders and the other Restricted Take-Down Selling Holders, the number of Registrable Securities calculated pursuant to Section 3.1(d)(ii)(B). It is
understood that in order to be entitled to exercise its, his or her right to sell Registrable Securities in a Restricted Shelf Take-Down pursuant to this Section 3.1(d)(iv), each Take-Down Tagging Holder must agree to make
the same representations, warranties, covenants, indemnities and agreements, if any, as the Shelf Take-Down Initiating Holders agree to make in connection with the Restricted Shelf Take-Down, with such additions or changes as are required of such
Take-Down Tagging Holder by the Underwriters (if applicable). 

  
 19 

 (D) Notwithstanding the delivery of any Restricted Shelf Take-Down Notice,
all determinations as to whether to complete any Restricted Shelf Take-Down and as to the timing, manner, price and other terms and conditions of any Restricted Shelf Take-Down shall be at the sole discretion of the applicable Shelf Take-Down
Initiating Holder, and PubCo agrees to cooperate in facilitating any Restricted Shelf Take-Down pursuant to Section 3.1(d). Each of the Shelf Holders agrees to reasonably cooperate with each of the other Shelf Holders and
PubCo to establish notice, delivery and documentation procedures and measures to facilitate such other Shelf Holders’ participation in Restricted Shelf Take-Downs pursuant to this Section 3.1(d). 

Section 3.2 Demand Registrations. 

(a) Holders’ Demand for Registration. If, at a time when a Shelf Registration Statement is not effective pursuant
to Section 3.1, PubCo shall receive from the Partners at any time following the Lock-up Period (the then eligible Holders, the “Demand Initiating Holders”) a written
demand that PubCo effect any Registration in connection with an Underwritten Offering other than a Shelf Registration or a Shelf Take-Down (a “Demand Registration”) of Registrable Securities held by such Holders, PubCo will:

 (i) use its reasonable best efforts to effect such registration as soon as practicable as will permit or facilitate the
sale and distribution of all or such portion of the Demand Initiating Holders’ Registrable Securities as are specified in such demand; provided, that PubCo shall not be obligated to file any Registration Statement or other disclosure document
pursuant to this Section 3.2 (but shall be obligated to continue to prepare such Registration Statement or other disclosure document) if PubCo shall furnish to the Demand Initiating Holders a certificate signed by the chief
executive officer or equivalent senior executive of PubCo, stating that the filing or effectiveness of such Registration Statement would require PubCo to make an Adverse Disclosure, in which case PubCo shall have an additional period (each, a
“Demand Delay”) of not more than forty-five (45) days within which to file such Registration Statement; provided, however, that PubCo shall not exercise, in any twelve (12) month period, (x) more than one
(1) Demand Delay pursuant to this Section 3.2(a)(i) and Shelf Suspension pursuant to Section 3.1(c) in the aggregate, unless consented in writing by the Demand Initiating Holders or
(y) aggregate Demand Delays pursuant to this Section 3.2(a)(i) and Shelf Suspensions pursuant to Section 3.1(c) of more than ninety (90) days. Each Holder shall keep confidential the fact
that a Demand Delay is in effect, the certificate referred to above and its contents for the permitted duration of the Demand Delay or until otherwise notified by PubCo, except (A) for disclosure to the Holder’s employees, agents and
professional advisers who need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such
information confidential and (C) as required by Law. 

  
 20 

 (b) Underwriting. If the Demand Initiating Holders intend to
distribute the Registrable Securities covered by their demand by means of an Underwritten Offering, they shall so advise PubCo as part of their demand made pursuant to this Section 3.2, and PubCo shall include such
information in the written notice referred to in Section 3.2(a)(i). In such event, the right of the Demand Initiating Holders’ registration pursuant to this Section 3.2 shall be conditioned
upon the Demand Initiating Holders’ participation in such Underwritten Offering and the inclusion of the Demand Initiating Holders’ Registrable Securities in the Underwritten Offering to the extent provided herein. PubCo, together with all
holders of Registrable Securities of PubCo proposing to distribute their securities through such Underwritten Offering, shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected by the Demand
Initiating Holders that own a majority of the Registrable Securities and reasonably satisfactory to PubCo. Notwithstanding any other provision of this Section 3.2, if the Underwriter shall advise PubCo that marketing
factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten, then PubCo shall so advise the Holders that have requested to participate in such Underwritten
Offering, and the number of Registrable Securities that may be included in the Demand Registration and Underwritten Offering shall be allocated pro rata among the Demand Initiating Holders and other holders of Registrable Securities exercising a
contractual or other right to dispose of Registrable Securities in such Underwritten Offering thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such persons at the time of filing the
Registration Statement; provided, that any Registrable Securities thereby allocated to any such person that exceed such person’s request shall be reallocated among the Demand Initiating Holders and other requesting holders of Registrable
Securities in like manner; and provided, further, that the number of Registrable Securities to be included in such Underwritten Offering shall not be reduced unless all other Equity Securities of PubCo are first entirely excluded from the
Underwritten Offering. No Registrable Securities excluded from the Underwritten Offering by reason of the Underwriter’s marketing limitation shall be included in such Demand Registration. If the Underwriter has not limited the number of
Registrable Securities to be underwritten, PubCo may include securities for its own account (or for the account of any other Persons) in such Demand Registration if the Underwriter so agrees and if the number of Registrable Securities would not
thereby be limited. 
 (c) Effective Registration. PubCo shall be deemed to have effected a Demand Registration if the
Registration Statement pursuant to such registration is declared effective by the SEC and remains continuously effective for not less than one hundred eighty (180) days (or such shorter period as will terminate when all Registrable Securities
covered by such Registration Statement have been sold or withdrawn), or, if such Registration Statement relates to an Underwritten 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 sales of Registrable Securities by an Underwriter or dealer (the applicable period, the “Demand Period”). No Demand Registration shall be deemed to have been effected if (i) during the Demand Period
such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other Governmental Entity or court or (ii) the conditions specified in the underwriting agreement, if any, entered into in connection
with such Registration are not satisfied other than by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement by a participating Holder. 

  
 21 

 Section 3.3 Piggyback Registration. 

(a) If at any time or from time to time PubCo shall determine to register any of its Equity Securities, either for its own
account or for the account of security holders, including (for the avoidance of doubt) the registration of shares of Common Stock subject to PubCo’s publicly-traded warrants (other than in (1) a registration relating solely to employee
benefit plans, (2) a registration statement on Form S-4 or S-8 (or such other similar successor forms then in effect under the Securities Act), (3) a registration
pursuant to which PubCo is offering to exchange its own securities for other securities, (4) a registration statement relating solely to dividend reinvestment or similar plans, (5) a Shelf Registration Statement pursuant to which only the
initial purchasers and subsequent transferees of debt securities of PubCo or any of its subsidiaries that are convertible for Common Stock and that are initially issued pursuant to Rule 144A and/or Regulation S (or any successor provision) of the
Securities Act may resell such notes and sell the Common Stock into which such notes may be converted, (6) a registration pursuant to Section 3.1 or Section 3.2 hereof or (7) a
registration expressly contemplated by the Note Subscription Agreements), PubCo will: 
 (i) promptly (but in no event less
than ten (10) days before the effective date of the relevant Registration Statement) give to each Holder written notice thereof; and 

(ii) include in such Registration (and any related qualification under state securities Laws or other compliance), and in any
Underwritten Offering involved therein, all the Registrable Securities specified in a written request or requests made within five (5) days after receipt of such written notice from PubCo by any Holder or Holders except as set forth in
Section 3.3(b) below. 
 Notwithstanding anything herein to the contrary, this Section 3.3 shall not
apply (i) to any Shelf Take-Down irrespective of whether such Shelf Take-Down is an Underwritten Shelf Take-Down or not an Underwritten Shelf Take-Down, or (ii) following the Lock-Up Period, to any
Distribution (if applicable). 
 (b) Underwriting. If the Registration of which PubCo gives notice pursuant to
Section 3.3(a) is for an Underwritten Offering, PubCo shall so advise the Holders as a part of the written notice given pursuant to Section 3.3(a)(i). In such event the right of any Holder to
participate in such registration pursuant to this Section 3.3 shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in the
Underwritten Offering to the extent provided herein. All Holders proposing to dispose of their Registrable Securities through such Underwritten Offering, together with PubCo and the other parties distributing their Equity Securities of PubCo through
such Underwritten Offering, shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Underwritten Offering by PubCo. Notwithstanding any other provision of this
Section 3.3, if the Underwriters shall advise PubCo that marketing factors (including an adverse effect on the per security offering price) require a limitation of the number of Registrable Securities to be underwritten,
then PubCo may limit the number of Registrable Securities to be included in the Registration and Underwritten Offering as follows: 

  
 22 

 (i) If the Registration is initiated and undertaken for PubCo’s
account, PubCo shall so advise all Holders of Registrable Securities that have requested to participate in such offering, and the number of Registrable Securities that may be included in the Registration and Underwritten Offering shall be allocated
in the following manner: (A) first, to PubCo, (B) second, to the Holders of Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by such Holders and (C) third, to other holders of Equity
Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities in such Underwritten Offering on a pro rata basis based on the total number of Equity Securities of PubCo held by such persons; provided, in the case of
this foregoing clause (C) that any Registrable Securities or Equity Securities thereby allocated to any such person that exceed such person’s request shall be reallocated among the remaining requesting Holders or other requesting
holders, as applicable, in like manner. 
 (ii) If the Registration is initiated and undertaken at the request of one or more
holders of Equity Securities of PubCo who are not Holders or their Affiliates, PubCo shall so advise all Holders of Registrable Securities that have requested to participate in such offering, and the number of Registrable Securities that may be
included in the Registration and Underwritten Offering shall be allocated in the following manner: (A) first, to the initiating holders of Equity Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities
in such Underwritten Offering, on a pro rata basis based on the total number of Equity Securities of PubCo, (B) second, to the Holders of Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by
such Holders, (C) third, to PubCo, (D) fourth, to other holders of Equity Securities of PubCo exercising a contractual or other right to dispose of such Equity Securities in such Underwritten Offering on a pro rata basis based on the total
number of Equity Securities of PubCo held by such persons; provided, in the case of this foregoing clause (D) that any Registrable Securities or Equity Securities thereby allocated to any such person that exceed such person’s
request shall be reallocated among the remaining requesting Holders or other requesting holders, as applicable, in like manner. 
 No such reduction
pursuant to the foregoing paragraphs (i) and (ii) shall reduce the amount of Registrable Securities of the selling Holders included in the Registration below twenty-five percent (25%) of the total amount of Equity Securities
included in such Registration. No securities excluded from the Underwritten Offering by reason of the Underwriter’s marketing limitation shall be included in such Registration. 

  
 23 

 (c) Right to Terminate Registration. PubCo shall have the right to
terminate or withdraw any Registration initiated by it under this Section 3.3 prior to the effectiveness of such Registration whether or not any Holder has elected to include Registrable Securities in such Registration. The
expenses of such withdrawn registration shall be borne by PubCo in accordance with Section 3.4 hereof. 

Section 3.4 Expenses of Registration. All Registration Expenses incurred in connection with all Registrations or other Transfers
effected pursuant to or permitted by this Investor Rights Agreement (including any Distribution), including, all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for PubCo, shall be
borne by PubCo. It is acknowledged by the Holders that the Holders selling or otherwise Transferring any Registrable Securities in any Registration or Transfer shall bear all incremental selling expenses relating to the sale of such Registrable
Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal
counsel representing such Holders, in each case pro rata based on the number of Registrable Securities that such Holders have sold or Transferred in such Registration. 

Section 3.5 Obligations of PubCo. Whenever required under this Article III to effect the Registration of any Registrable
Securities, PubCo shall, as expeditiously as reasonably possible: 
 (a) prepare and file with the SEC a Registration
Statement with respect to such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective, and, upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days (or for such period of time specified in Section 3.1) or, if earlier, until the distribution
contemplated in the registration statement has been completed, or until all Registrable Securities covered by such Registration Statement have been sold; 

(b) prepare and file with the SEC such amendments, post-effective amendments and supplements to such Registration Statement and
the Prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by
such Registration Statement in accordance with the intended methods of disposition by sellers thereof set forth in such Registration Statement; 

(c) permit any Holder that (in the good faith reasonable judgment of the Partners) might be deemed to be a controlling person
of PubCo to participate in good faith in the preparation of such Registration Statement and to cooperate in good faith to include therein material, furnished to PubCo in writing, that in the reasonable judgment of such Holder and its counsel should
be included; 
 (d) furnish to the Holders such numbers of copies of the Registration Statement and the related Prospectus,
including all exhibits thereto and documents incorporated by reference therein and a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate

thereto; 

  
 26 

 (s) notify each selling Holder, promptly after PubCo receives notice

 Section 3.6
Indemnification. 
 (a) PubCo will, and does hereby undertake to, indemnify and hold harmless each Holder of
Registrable Securities and each of such Holder’s officers, directors, trustees, employees, partners, managers, members, equityholders, beneficiaries, affiliates and agents and each Person, if any, who controls such Holder, within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect to any Registration, qualification, compliance or sale effected pursuant to this Article III, and each Underwriter, if any, and each Person who
controls any Underwriter, of the Registrable Securities held by or issuable to such Holder, against all claims, losses, damages and liabilities (or actions in respect thereto) to which they may become subject under the Securities Act, the Exchange
Act, or other federal or state Law arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular, free writing prospectus or other similar document (including
any related Registration Statement, notification, or the like) incident to any such Registration, qualification, compliance or sale effected pursuant to this Article III, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, (B) any violation or alleged violation by PubCo of any Law applicable to PubCo in
connection with any such Registration, qualification, compliance or sale, or (C) any failure to register or qualify Registrable Securities in any state where PubCo or its agents have affirmatively undertaken or agreed in writing (including
pursuant to Section 3.5(k)) that PubCo (the undertaking of any Underwriter being attributed to PubCo) will undertake such Registration or qualification on behalf of the Holders of such Registrable Securities (provided, that
in such instance PubCo shall not be so liable if it has undertaken its reasonable best efforts to so register or qualify such Registrable Securities) and will reimburse, as incurred, each such Holder, each such Underwriter and each such director,
officer, trustee, employee, partner, manager, member, equityholder, beneficiary, affiliate, agent and controlling person, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss,
damage, liability or action; provided, that PubCo will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission made in reliance and in
conformity with written information furnished to PubCo by such Holder or Underwriter expressly for use therein. 

  
 27 

 (b) Each Holder (if Registrable Securities held by or issuable to such
Holder are included in such Registration, qualification, compliance or sale pursuant to this Article III) does hereby undertake to indemnify and hold harmless, severally and not jointly, PubCo, each of its officers, directors, employees,
affiliates and agents and each Person, if any, who controls PubCo within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each Underwriter, if any, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, prospectus, offering circular, free writing prospectus or
other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, and will
reimburse, as incurred, PubCo, each of its officers, directors, employees, affiliates and agents and each Person, if any, who controls PubCo within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act,
and each Underwriter, if any, for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such
untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in such Registration Statement, prospectus, offering circular, free writing prospectus or other document, in reliance upon and in conformity with written
information that (i) relates to such Holder in its capacity as a selling security holder and (ii) was furnished to PubCo by such Holder expressly for use therein; provided, however, that the aggregate liability of each Holder hereunder
shall be limited to the net proceeds after underwriting discounts and commissions received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. It is understood and agreed that the
indemnification obligations of each Holder pursuant to any underwriting agreement entered into in connection with any Registration Statement shall be limited to the obligations contained in this Section 3.6(b). 

(c) Each party entitled to indemnification under this Section 3.6 (the “Indemnified
Party”) shall give notice to the party required to provide such indemnification (the “Indemnifying Party”) of any claim as to which indemnification may be sought promptly after such Indemnified Party has actual knowledge
thereof, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be
subject to approval by the Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at the Indemnifying Party’s expense if representation of such Indemnified Party would be
inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding; and provided, further, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations under this Section 3.6, except to the extent that such failure to give notice materially prejudices the Indemnifying Party in the defense of any
such claim or any such litigation. An 

  
 28 

 
Indemnifying Party, in the defense of any such claim or litigation, may, without the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that
(i) includes as a term thereof the giving by the claimant or plaintiff therein to such Indemnified Party of an unconditional release from all liability with respect to such claim or litigation and (ii) does not include any recovery
(including any statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Indemnified Party) other than monetary damages, and provided, that any sums payable in connection with such settlement are paid in full
by the Indemnifying Party. 
 (d) In order to provide for just and equitable contribution in case indemnification is
prohibited or limited by Law, the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of material fact or
omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and such Person’s relative intent, knowledge, access to information and opportunity to
correct or prevent such actions; provided, however, that, in any case, (i) no Holder will be required to contribute any amount in excess of the net proceeds after Underwriting discounts and commissions received by such Holder upon the sale of
the Registrable Securities giving rise to such contribution obligation and (ii) 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 was not guilty of such fraudulent misrepresentation. 
 (e) The indemnities provided in this
Section 3.6 shall survive the Transfer of any Registrable Securities by such Holder. 
 Section 3.7
Information by Holder. The Holder or Holders of Registrable Securities included in any Registration shall furnish to PubCo such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as PubCo may
reasonably request in writing and as shall be required in connection with any Registration, qualification or compliance referred to in this Article III. Each Holder agrees, if requested in writing by PubCo, to represent to PubCo the total number of
Registrable Securities held by such Holder in order for PubCo to make determinations under this Investor Rights Agreement, including for purposes of Section 3.9 hereof. Notwithstanding anything to the contrary contained in
this Investor Rights Agreement, if any Holder does not provide PubCo with information requested pursuant to this Section 3.7, PubCo may exclude such Holder’s Registrable Securities from the applicable Registration Statement or
Prospectus if PubCo determines, based on the advice of outside counsel, that such information is necessary to effect the Registration and such Holder continues thereafter to withhold such information. No Person may participate in any Underwritten
Offering of Equity Securities of PubCo pursuant to a Registration under this Investor Rights Agreement unless such Person completes and executes all customary questionnaires, powers of attorney, custody agreements,

  
 29 

 
indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting
arrangements. Subject to the minimum thresholds set forth in Section 3.1(d)(ii) and Section 3.2(a) of this Investor Rights Agreement, the exclusion of a Holder’s Registrable Securities as a result of this Section 3.7 shall
not affect the registration of the other Registrable Securities to be included in such Registration. 
 Section 3.8 Delay of
Registration. No Holder shall have any right to obtain, and hereby waives any right to seek, an injunction restraining or otherwise delaying any such Registration as the result of any controversy that might arise with respect to the
interpretation or implementation of this Article III. 
 Section 3.9 Rule 144 Reporting. With a view to making available
to the Holders the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without Registration, PubCo agrees to use its reasonable best efforts to: 

(a) make and keep current public information available, within the meaning of Rule 144 (or any similar or analogous rule)
promulgated under the Securities Act, at all times; 
 (b) file with the SEC, in a timely manner, all reports and other
documents required of PubCo under the Securities Act and Exchange Act; and 
 (c) so long as a Holder owns any Registrable
Securities, furnish to such Holder forthwith upon request a written statement by PubCo as to its compliance with the reporting requirements of said Rule 144 (at any time commencing after the Lock-Up Period),
the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of PubCo and such other reports and documents as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without Registration. 
 Section 3.10 “Market Stand Off” Agreement. 

(a) Each Holder hereby agrees that, with respect to Underwritten Offerings initiated by a Holder only, during such period
(which period shall in no event exceed ninety (90) days) following the effective date of a Registration Statement of PubCo (or, in the case of an Underwritten Shelf Take-Down, the date of the filing of a preliminary Prospectus or Prospectus
supplement relating to such Underwritten Offering (or if there is no such filing, the first contemporaneous press release announcing commencement of such Underwritten Offering)) as the Holders that own a majority of the Registrable Securities
participating in such Underwritten Offering may agree to with the Underwriter or Underwriters of such Underwritten Offering (a “Market Stand-Off Period”), such Holder or its Affiliates shall
not sell, pledge, hypothecate, transfer, make any short sale of, loan, grant any option or right to purchase of, or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any Registrable Securities held by it at any
time during such period except Registrable Securities included in such Registration and shares of Common Stock subject to a Charitable Distribution in connection with such Underwritten Offering. In connection with any Underwritten Offering
contemplated by this 

  
 30 

 
Section 3.10, PubCo shall use reasonable best efforts to cause each director and executive officer of PubCo to execute a customary
lock-up for the Market Stand-Off Period. Each Holder agrees that it shall deliver to the Underwriter or Underwriters for any such Underwritten Offering a customary
agreement (with customary terms, conditions and exceptions) that is substantially similar to the agreement delivered to the Underwriter or Underwriters by the Holders that own a majority of the Registrable Securities participating in such
Registration reflecting their agreement set forth in this Section 3.10; provided, that such agreement shall not be materially more restrictive than any similar agreement entered into by PubCo’s directors and executive
officers participating in such Underwritten Offering; provided, further, that such agreement shall not be required unless all Holders are required to enter into similar agreements; provided, further, that such agreement shall provide that any early
release of any Holder from the provisions of the terms of such agreement shall be on a pro rata basis among all Holders. 

Section 3.11 Other Obligations. In connection with a Transfer of Registrable Securities exempt from Section 5 of the
Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within the Prospectus and pursuant to the Registration Statement of which such Prospectus forms a part, PubCo shall, subject to applicable Law,
as interpreted by PubCo with the advice of counsel, and the receipt of any customary documentation required from the applicable Holders in connection therewith, (a) promptly instruct its transfer agent to remove any restrictive legends
applicable to the Registrable Securities being Transferred and (b) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under the foregoing clause (a). In
addition, PubCo shall cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with the aforementioned Transfers; provided, however, that PubCo shall have no obligation to participate in
any “road shows” or assist with the preparation of any offering memoranda or related documentation with respect to any Transfer of Registrable Securities in any transaction that does not constitute an Underwritten Offering. 

Section 3.12 Other Registration Rights. Other than the registration rights set forth in the Original RA and in the Note
Subscription Agreements, PubCo represents and warrants that no Person, other than a Holder of Registrable Securities pursuant to this Investor Rights Agreement, has any right to require PubCo to register any securities of PubCo for sale or to
include such securities of PubCo in any Registration Statement filed by PubCo for the sale of securities for its own account or for the account of any other Person. Further, each of PubCo, the Sponsor and the Financial Services Representatives
acknowledges, agrees, represents and warrants that this Investor Rights Agreement supersedes any other registration rights agreement or agreement (including the Original RA), other than the Note Subscription Agreements. 

Section 3.13 Term. Article III shall terminate with respect to any Holder on the date that such Holder no longer holds any
Registrable Securities. The provisions of Section 3.6 shall survive any such termination with respect to such Holder. 

Section 3.14 Termination of Original RA. Upon the Closing, PubCo, the Sponsor, the Original Underwriter Representatives, Brad
Weightman and Dorothy Hayes hereby agree that the Original RA and all of the respective rights and obligations of the parties thereunder are hereby terminated in their entirety and shall be of no further force or effect. 

  
 31 

 ARTICLE IV 

LOCK-UP 

Section 4.1 Lock-Up. 

(a) Each Holder (other than the Financial Services Representatives) severally, and not jointly, agrees not to effect any
Transfer, or make a public announcement of any intention to effect such Transfer, of any Lock-Up Shares (as defined below) Beneficially Owned or otherwise held by such Person during the Lock-Up Period; provided, that such prohibition shall not apply to Transfers (i) permitted pursuant to Section 4.2, or (ii) permitted pursuant to Article III. For the
avoidance of doubt, each Holder agrees not to effect a Distribution during the Lock-Up Period. The “Lock-Up Shares” means the Registrable Securities
held by the Holders (other than the Financial Services Representatives) as of the Closing Date (other than, with respect to the Sponsor and the Original Underwriter Representatives, the Private Units (as defined in the Insider Letter) and the
securities underlying the Private Units (collectively, the “Private PubCo Equity Securities”)). 
 (b)
During the Lock-Up Period, any purported Transfer of Lock-Up Shares not in accordance with this Investor Rights Agreement shall be null and void, and PubCo shall refuse
to recognize any such Transfer for any purpose. 
 (c) The Holders acknowledge and agree that, notwithstanding anything to
the contrary contained in this Investor Rights Agreement, the Lock-Up Shares Beneficially Owned by such Person shall remain subject to any restrictions on Transfer under applicable securities Laws of any
Governmental Entity, including all applicable holding periods under the Securities Act and other rules of the SEC. 
 (d)
PubCo, the Sponsor and the Original Underwriter Representatives hereby agree that the Insider Letter is hereby amended such that the provisions of Section 9 thereof shall not apply or have any further effect with respect to any Registrable
Securities other than any Private PubCo Equity Securities (and, for the avoidance of doubt, the provisions of Section 9 of the Insider Letter shall only apply to the Private PubCo Equity Securities to the extent such provisions are expressly
applicable thereto). Except as amended by this subclause (d), the provisions of the Insider Letter shall remain in full force and effect. 

Section 4.2 Permitted Transfers. Notwithstanding anything to the contrary contained in this Investor Rights Agreement, during the Lock-Up Period, the Holders may Transfer, without the consent of PubCo, any of such Person’s Lock-Up Shares to (i) any of such Person’s Permitted Transferees,
upon written notice to PubCo and, in the case of such a Transfer by the Sponsor or any of the Financial Services Representatives, the Partners, and in the case of such a Transfer by the Partners or their Permitted Transferees, the Sponsor and the
Financial Services Representatives, (ii) (a) in the case of an individual, by virtue of Laws of descent and distribution upon death of the individual; (b) in the case of an individual, pursuant to a qualified domestic relations order; or
(c) pursuant to any liquidation, merger, stock exchange or other similar transaction which results in all of PubCo’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent
to the Business Combination, 

  
 32 

 
(iii) a charitable organization through a Charitable Distribution (which for avoidance of doubt shall be deemed separate from a Transfer pursuant to clause (ii)(a) above), (iv) PubCo in
connection with the “net” or “cashless” exercise or settlement of warrants or stock options, restricted stock units or other equity awards (and any transfer to PubCo necessary to generate such amount of cash needed for the
payment of taxes, including estimated taxes, due as a result of such vesting, settlement or exercise whether by means of a “net settlement” or otherwise), or (v) PubCo in connection with the repurchase of shares of Common Stock issued
pursuant to equity awards granted under a stock incentive plan or other equity award plan or pursuant to the agreements under which such shares were issued, provided that such repurchase of shares of Common Stock is in connection with the
termination of such Holder’s service provider relationship with PubCo; provided, that in connection with any Transfer of such Lock-Up Shares pursuant to clause (ii) above, (x) the
restrictions and obligations contained in Section 4.1 and this Section 4.2 will continue to apply to such Lock-Up Shares after any Transfer of such Lock-Up Shares and such Transferee shall agree to be bound by such restrictions and obligations in writing and acknowledged by PubCo, and (y) the Transferee of such
Lock-Up Shares shall have no rights under this Investor Rights Agreement, unless, for the avoidance of doubt, such Transferee is a Permitted Transferee in accordance with this Investor Rights Agreement. Any
Transferee of Lock-Up Shares who is a Permitted Transferee of the Transferor pursuant to this Section 4.2 shall be required, at the time of and as a condition to such Transfer, to
become a party to this Investor Rights Agreement by executing and delivering a joinder in the form attached to this Investor Rights Agreement as Exhibit A, whereupon such Transferee will be treated as a Party (with the same rights and
obligations as the Transferor) for all purposes of this Investor Rights Agreement. Notwithstanding the foregoing provisions of this Section 4.2, a Holder may not make a Transfer to a Permitted Transferee if such Transfer
has as a purpose the avoidance of or is otherwise undertaken in contemplation of avoiding the restrictions on Transfers in this Agreement (it being understood that the purpose of this provision includes prohibiting the Transfer to a Permitted
Transferee (A) that has been formed to facilitate a material change with respect to who or which entities Beneficially Own the underlying Lock-Up Shares, or (B) followed by a change in the
relationship between the Holder and the Permitted Transferee (or a change of control of such Holder or Permitted Transferee) after the Transfer with the result and effect that the Holder has indirectly made a Transfer of Lock-Up Shares by using a Permitted Transferee, which Transfer would not have been directly permitted under this Article IV had such change in such relationship occurred prior to such Transfer). 

ARTICLE V 
 GENERAL
PROVISIONS 
 Section 5.1 Assignment; Successors and Assigns; No Third Party Beneficiaries. 

(a) Except as otherwise permitted pursuant to this Investor Rights Agreement, no Party may assign such Party’s rights and
obligations under this Investor Rights Agreement, in whole or in part, without the prior written consent of the Partners. Any such assignee may not again assign those rights, other than in accordance with this Article V. Any attempted
assignment of rights or obligations in violation of this Article V shall be null and void. 

  
 33 

 (b) Notwithstanding anything to the contrary contained in this Investor
Rights Agreement (other than the succeeding sentence of this Section 5.1(b)), (i) prior to the expiration of the Lock-Up Period to the extent applicable to such Holder, no Holder may
Transfer such Holder’s rights or obligations under this Investor Rights Agreement in connection with a Transfer of such Holder’s Registrable Securities, in whole or in part, except in connection with a Transfer pursuant to
Section 4.2; and (ii) after the expiration of the Lock-up Period to the extent applicable to such Holder, a Holder may Transfer such Holder’s rights or obligations under
this Investor Rights Agreement in connection with a Transfer of such Holder’s Registrable Securities, in whole or in part, to (x) any of such Holder’s Permitted Transferees (other than any charitable organization), or (y) any
Person with the prior written consent of PubCo. In no event can the Sponsor or the Partners assign any of such Person’s rights under Section 2.1. Any Transferee of Registrable Securities (other than pursuant to an
effective registration statement under the Securities Act, pursuant to a Rule 144 transaction or pursuant to any In-Kind Distribution) shall, except as otherwise expressly stated herein, have all the rights
and be subject to all of the obligations of the Transferor Holder under this Investor Rights Agreement and shall be required, at the time of and as a condition to such Transfer, to become a party to this Investor Rights Agreement by executing and
delivering a joinder in the form attached to this Investor Rights Agreement as Exhibit A. No Transfer of Registrable Securities by a Holder shall be registered on PubCo’s books and records, and such Transfer of Registrable
Securities shall be null and void and not otherwise effective, unless any such Transfer is made in accordance with the terms and conditions of this Investor Rights Agreement, and PubCo is hereby authorized by all of the Holders to enter appropriate
stop transfer notations on its transfer records to give effect to this Investor Rights Agreement. 
 (c) All of the terms and
provisions of this Investor Rights Agreement shall be binding upon the Parties and their respective successors, assigns, heirs and representatives, but shall inure to the benefit of and be enforceable by the successors, assigns, heirs and
representatives of any Party only to the extent that they are permitted successors, assigns, heirs and representatives pursuant to the terms of this Investor Rights Agreement. 

(d) Other than as expressly set forth in this Agreement, nothing in this Investor Rights Agreement, express or implied, is
intended to confer upon any Party, other than the Parties and their respective permitted successors, assigns, heirs and representatives, any rights or remedies under this Investor Rights Agreement or otherwise create any third party beneficiary
hereto. 
 Section 5.2 Termination. Except for Section 2.1(g) (which section shall terminate at such time as the
Partners, the Sponsor and their Permitted Transferees are no longer entitled to any rights pursuant to such section), Article II shall terminate automatically (without any action by any Party) as to the Partners or the Sponsor at such time at
which such Party no longer has the right to designate an individual for nomination to the Board under this Investor Rights Agreement. Except for Section 3.6 (which section shall terminate at such time as the Partners, the Sponsor, the
Financial Services Representatives and their Permitted Transferees are no longer entitled to any rights pursuant to such section), Article III of this Investor Rights Agreement shall terminate as set forth in Section 3.13. The
remainder of this Investor Rights Agreement shall terminate automatically (without any action by any Party) as to each Holder when such Holder, following 

  
 34 

 
the Closing Date, ceases to Beneficially Own any Registrable Securities; provided, that the provisions of Section 5.11, Section 5.12 and Section 5.13 shall
survive any such termination with respect to such Holder. Notwithstanding anything herein to the contrary, in the event the Merger Agreement terminates in accordance with its terms prior to the Closing, this Investor Rights Agreement shall
automatically terminate and be of no further force or effect, without any further action required by the Parties. 
 Section 5.3
Severability. If any provision of this Investor Rights Agreement is determined to be invalid, illegal or unenforceable by any Governmental Entity, the remaining provisions of this Investor Rights Agreement, to the extent permitted by Law
shall remain in full force and effect. 
 Section 5.4 Entire Agreement; Amendments; No Waiver. 

(a) This Investor Rights Agreement, as it amends and restates the Original Investor Rights Agreement, together with the Exhibit
to this Investor Rights Agreement, the Merger Agreement and all other Transaction Agreements (as such term is defined in the Merger Agreement), constitute the entire agreement among the Parties with respect to the subject matter hereof and thereof
and supersede all prior and contemporaneous agreements, understandings and discussions, whether oral or written, relating to such subject matter in any way, and there are no warranties, representations or other agreements among the Parties in
connection with such subject matter except as set forth in this Investor Rights Agreement and therein. 
 (b) No provision of
this Investor Rights Agreement may be amended or modified in whole or in part at any time without the express written consent of (i) PubCo, (ii) for so long as the Partners collectively Beneficially Own Common Stock representing 10% or more of
the Common Stock Beneficially Owned by the Partners immediately after the Closing, the Partners, and (iii) in any event, at least the Holders holding in the aggregate more than fifty percent (50%) of the Registrable Securities Beneficially
Owned by the Holders; provided, that any such amendment or modification that adversely and disproportionately affects any Holder or Holders, as compared to any other Holder or Holders, shall require the prior written consent of such Holders who
Beneficially Own a majority of the Registrable Securities Beneficially Owned by all such Holders so adversely and disproportionately affected; provided, further that any amendment or modification to Article III, Article IV,
Section 5.12, Section 5.13, Section 5.15 or this Section 5.4 that adversely affects any right granted to the Partners, the Sponsor or the
Financial Services Representatives, shall require the consent of the Partners, the Sponsor or the Financial Services Representatives, as applicable; provided, further that any amendment or modification to Article II that adversely affects any
right granted to the Partners or the Sponsor shall require the consent of the Partners or the Sponsor, as applicable; provided, further that a provision that has terminated with respect to a Party shall not require any consent of such Party (and
such Party’s Common Stock shall not be considered in computing any percentages) with respect to amending or modifying such provision. 

(c) No waiver of any provision or default under, nor consent to any exception to, the terms of this Investor Rights Agreement
shall be effective unless in writing and signed by the Party to be bound and then only to the specific purpose, extent and instance so provided.

and any other agreements, certificates, instruments and documents delivered pursuant to this Investor Rights Agreement may be executed and delivered in one or more counterparts and by email or other electronic transmission, each of which shall be
deemed an original and all of which shall be considered one and the same agreement. No Party shall raise the use of email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the
use of email as a defense to the formation or enforceability of a contract and each Party forever waives any such defense. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in

Section 5.7 Governing Law; Waiver of Jury Trial; Jurisdiction. The Law of the State of Delaware shall govern (a) all Actions,
claims or matters related to or arising from this Investor Rights Agreement (including any tort or non-contractual claims) and (b) any questions concerning the construction, interpretation, validity and
enforceability of this Investor Rights Agreement, and the performance of the obligations imposed by this Investor Rights Agreement, in each case 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 Law of any jurisdiction other than the State of Delaware. EACH PARTY TO THIS INVESTOR RIGHTS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION
BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS INVESTOR RIGHTS AGREEMENT, THE TRANSACTIONS CONTEMPLATED BY THIS
INVESTOR RIGHTS AGREEMENT AND/OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES UNDER THIS INVESTOR RIGHTS AGREEMENT. THE PARTIES FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH SUCH PARTY’S LEGAL COUNSEL, AND THAT EACH
KNOWINGLY AND VOLUNTARILY WAIVES SUCH PARTY’S JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. Each of the Parties submits to the exclusive jurisdiction of first, the Chancery Court of the State of Delaware or if such court declines
jurisdiction, then to the Federal District Court for the District of Delaware, in any Action arising out of or relating to this Investor Rights Agreement, agrees that all claims in respect of the Action shall be heard and determined in any such
court and agrees not to bring any Action arising out of or relating to this Investor Rights Agreement in any other courts. Each Party irrevocably consents to the service of process in any such Action by the mailing of copies thereof by registered or
certified mail, postage prepaid, to such Party, at its address for notices as provided in Section 5.6 of this Investor Rights Agreement, such service to become effective ten (10) days after such mailing. Each Party hereby
irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any Action commenced hereunder or under any other documents contemplated hereby that service of process was in any way
invalid or ineffective. Nothing in this Section 5.7, however, shall affect the right of any Party to serve legal process in any other manner permitted by Law or at equity; provided, that each of the Parties hereby waives any right it may
have under the Laws of any jurisdiction to commence by publication any Action with respect to this Investor Rights Agreement. To the fullest extent permitted by applicable Law, each of the Parties hereby

  
 39 

 
irrevocably waives any objection it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Investor Rights Agreement in any of the courts referred to in
this Section 5.7 and hereby further irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such Action. Each Party agrees that a final judgment in any Action so brought
shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law or at equity, in any jurisdiction. 

Section 5.8 Specific Performance. Each Party hereby agrees and acknowledges that it will be impossible to measure in money the
damages that would be suffered if the Parties fail to comply with any of the obligations imposed on them by this Investor Rights Agreement and that, in the event of any such failure, an aggrieved Party will be irreparably damaged and will not have
an adequate remedy at Law. Any such Party shall, therefore, be entitled (in addition to any other remedy to which such Party may be entitled at Law or in equity) to seek injunctive relief, including specific performance, to enforce such obligations,
without the posting of any bond, and if any Action should be brought in equity to enforce any of the provisions of this Investor Rights Agreement, none of the Parties shall raise the defense that there is an adequate remedy at Law. 

Section 5.9 Subsequent Acquisition of Shares. Any Equity Securities of PubCo acquired subsequent to the Effective Date by a Holder
shall be subject to the terms and conditions of this Investor Rights Agreement (other than the terms and conditions of Article IV) and such shares shall be considered to be “Registrable Securities” as such term is used in this
Investor Rights Agreement. 
 Section 5.10 Consents, Approvals and Actions. If any consent, approval or action of the Partners,
the Sponsor or the Financial Services Representatives is required or permitted at any time pursuant to this Investor Rights Agreement, such consent, approval or action shall be deemed given if the holders of a majority of the outstanding Equity
Securities of PubCo held by the Partners, the Sponsor, or the Financial Services Representatives, respectively, at such time provide such consent, approval or action in writing at such time; provided that, for the avoidance of doubt, the designation
of the Joint Director pursuant to Section 2.1(a) shall require the consent of both (i) the holders of a majority of the outstanding Equity Securities of PubCo held by the Partners and (ii) the holders of a majority of the
outstanding Equity Securities of PubCo held by Sponsor. 
 Section 5.11 Not a Group; Independent Nature of Holders’ Obligations
and Rights. The Holders and PubCo agree that the arrangements contemplated by this Investor Rights Agreement are not intended to constitute the formation of a “group” (as defined in Section 13(d)(3) of the Exchange Act). Each
Holder agrees that, for purposes of determining beneficial ownership of such Holder, it shall disclaim any beneficial ownership by virtue of this Investor Rights Agreement of PubCo’s Equity Securities owned by the other Holders, and PubCo
agrees to recognize such disclaimer in its Exchange Act and Securities Act reports. The obligations of each Holder under this Investor Rights Agreement are several and not joint with the obligations of any other Holder, and no Holder shall be
responsible in any way for the performance of the obligations of any other Holder under this Investor Rights Agreement. Nothing contained herein, and no action taken by any Holder pursuant hereto, shall be deemed to constitute the Holders as, and
PubCo acknowledges that the Holders do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group or entity with
respect to such obligations or the transactions contemplated by this Investor 

  
 40 

 
Rights Agreement, and PubCo acknowledges that the Holders are not acting in concert or as a group, and PubCo shall not assert any such claim, with respect to such obligations or the transactions
contemplated by this Investor Rights Agreement. Subject to Section 5.17, the decision of each Holder to enter into this Investor Rights Agreement has been made by such Holder independently of any other Holder. Subject to
Section 5.17, each Holder acknowledges that no other Holder has acted as agent for such Holder in connection with such Holder making its investment in PubCo and that no other Holder will be acting as agent of such Holder in
connection with monitoring such Holder’s investment in the Common Stock or enforcing its rights under this Investor Rights Agreement. PubCo and each Holder confirms that each Holder has had the opportunity to independently participate with
PubCo and its subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Holder shall be entitled to independently protect and enforce its rights, including, without limitation, the
rights arising out of this Investor Rights Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement to effectuate the rights and obligations
contemplated hereby was solely in the control of PubCo, not the action or decision of any Holder, and was done solely for the convenience of PubCo and its subsidiaries and not because it was required to do so by any Holder. It is expressly
understood and agreed that each provision contained in this Investor Rights Agreement is between PubCo and a Holder, solely, and not between PubCo and the Holders collectively and not between and among the Holders. 

Section 5.12 Other Business Opportunities. 

(a) The Parties expressly acknowledge and agree that to the fullest extent permitted by applicable Law: (i) each of the
Institutional Partners, the Sponsor and the Financial Services Representatives (including (A) their respective Affiliates, (B) any portfolio company in which they or any of their respective investment fund Affiliates have made a debt or
equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the Partner Directors and the Sponsor Directors
has the right to, and shall have no duty (fiduciary, contractual or otherwise) not to, directly or indirectly engage in and possess interests in other business ventures of every type and description, including those engaged in the same or similar
business activities or lines of business as PubCo or any of its subsidiaries or deemed to be competing with PubCo or any of its subsidiaries, on its own account, or in partnership with, or as an employee, officer, director or shareholder of any
other Person, with no obligation to offer to PubCo or any of its subsidiaries, or any other Holder the right to participate therein; (ii) each of the Institutional Partners, the Sponsor and the Financial Services Representatives (including
(A) their respective Affiliates, (B) any portfolio company in which they or any of their respective investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the Partner Directors and the Sponsor Directors may invest in, or provide services to, any Person that directly or indirectly competes with
PubCo or any of its subsidiaries; and (iii) in the event that any of the Institutional Partners, the Sponsor or the Financial Services Representatives (including (A) their respective Affiliates, (B) any portfolio company in which they
or any of their respective investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing

  
 41 

 
members or other similar direct or indirect investors) or any Partner Director or Sponsor Director, respectively, acquires knowledge of a potential transaction or matter that may be a corporate
or other business opportunity for PubCo or any of its subsidiaries, such Person shall have no duty (fiduciary, contractual or otherwise) to communicate or present such corporate opportunity to PubCo or any of its subsidiaries or any other Holder, as
the case may be, and, notwithstanding any provision of this Investor Rights Agreement to the contrary, shall not be liable to PubCo or any of its subsidiaries or any other Holder (or its Affiliates) for breach of any duty (fiduciary, contractual or
otherwise) by reason of the fact that such Person, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not present such opportunity to PubCo or any of its subsidiaries or any
other Holder (or its Affiliates). For the avoidance of doubt, the Parties acknowledge that this paragraph is intended to disclaim and renounce, to the fullest extent permitted by applicable Law, any right of PubCo or any of its subsidiaries with
respect to the matters set forth herein, and this paragraph shall be construed to effect such disclaimer and renunciation to the fullest extent permitted by Law. 

(b) Each of the Parties hereby, to the fullest extent permitted by applicable Law: 

(i) confirms that none of the Institutional Partners, the Sponsor or the Financial Services Representatives or any of their
respective Affiliates have any duty to PubCo or any of its subsidiaries or to any other Holder other than the specific covenants and agreements set forth in this Investor Rights Agreement; 

(ii) acknowledges and agrees that (A) in the event of any conflict of interest between PubCo or any of its subsidiaries,
on the one hand, and any of the Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates (or any Partner Director or Sponsor Director acting in his or her capacity as such), on the other hand,
the Institutional Partners, the Sponsor, the Financial Services Representatives or applicable Affiliates (or any Partner Director or Sponsor Director acting in his or her capacity as a director) may act in its best interest and (B) none of the
Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates or any Partner Director or Sponsor Director acting in his or her capacity as a director, shall be obligated (1) to reveal to PubCo
or any of its subsidiaries confidential information belonging to or relating to the business of such Person or any of its Affiliates or (2) to recommend or take any action in its capacity as a direct or indirect stockholder or director, as the
case may be, that prefers the interest of PubCo or its subsidiaries over the interest of such Person; and 
 (iii) waives any
claim or cause of action against any of the Institutional Partners, the Sponsor, the Financial Services Representatives and any of their respective Affiliates, and any officer, employee, agent or Affiliate of any such Person that may from time to
time arise in respect of a breach by any such person of any duty or obligation disclaimed under Section 5.12(b)(i) or Section 5.12(b)(ii). 

  
 42 

 (c) Each of the Parties hereto agrees that the waivers, limitations,
acknowledgments and agreements set forth in this Section 5.12 shall not apply to any alleged claim or cause of action against any of the Institutional Partners, the Sponsor or the Financial Services Representatives based
upon the breach or nonperformance by such Person of this Investor Rights Agreement or any other agreement to which such Person is a party. 

(d) The provisions of this Section 5.12, to the extent that they restrict the duties and liabilities
of any of the Institutional Partners, the Sponsor, the Financial Services Representatives or any of their respective Affiliates or any Partner Director or Sponsor Director otherwise existing at Law or in equity, are agreed by the Parties to replace
such other duties and liabilities of the Institutional Partners, the Sponsor, the Original Financial Services Representatives or any of their respective Affiliates or any such Partner Director or Sponsor Director to the fullest extent permitted by
applicable Law. 
 Section 5.13 Indemnification; Exculpation. 

(a) PubCo will, and PubCo will cause each of its subsidiaries to, jointly and severally indemnify, exonerate and hold the
Holders and each of their respective direct and indirect partners, equityholders, members, managers, Affiliates, directors, officers, shareholders, fiduciaries, managers, controlling Persons, employees, representatives and agents and each of the
partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of each of the foregoing (collectively, the “Holder Indemnitees”) free and harmless from and against
any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and out-of-pocket expenses in connection therewith (including reasonable
attorneys’ fees and expenses) incurred by the Holder Indemnitees or any of them before or after the date of this Investor Rights Agreement (collectively, the “Indemnified Liabilities”), arising out of any action, cause of
action, suit, litigation, investigation, inquiry, arbitration or claim (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) any Holder’s or its Affiliates’ ownership of Equity
Securities of PubCo or control or ability to influence PubCo or any of its subsidiaries (other than any such Indemnified Liabilities (x) to the extent such Indemnified Liabilities arise out of any breach of this Investor Rights Agreement by
such Holder Indemnitee or its Affiliates or other related Persons or the breach of any fiduciary or other duty or obligation of such Holder Indemnitee to its direct or indirect equity holders, creditors or Affiliates, (y) to the extent such
control or the ability to control PubCo or any of its subsidiaries derives from such Holder’s or its Affiliates’ capacity as an officer or director of PubCo or any of its subsidiaries or (z) to the extent such Indemnified Liabilities
are directly caused by such Person’s willful misconduct), (ii) the business, operations, properties, assets or other rights or liabilities of PubCo or any of its subsidiaries or (iii) any services provided prior to, on or after the date of
this Investor Rights Agreement by any Holder or its Affiliates to PubCo or any of their respective subsidiaries; provided, however, that if and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, PubCo
will, and will cause its subsidiaries to, make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable Law. For the purposes of this Section 5.13,
none of the circumstances described in the limitations contained in the proviso in the immediately preceding sentence shall be deemed to apply absent a final non-appealable judgment of a court of competent
jurisdiction to such effect, in which case to 

  
 43 

 
the extent any such limitation is so determined to apply to any Holder Indemnitee as to any previously advanced indemnity payments made by PubCo or any of its subsidiaries, then such payments
shall be promptly repaid by such Holder Indemnitee to PubCo and its subsidiaries. The rights of any Holder Indemnitee to indemnification hereunder will be in addition to any other rights any such Person may have under any other agreement or
instrument to which such Holder Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under Law or regulation or under the organizational or governing documents of PubCo or its subsidiaries. 

(b) PubCo will, and will cause each of its subsidiaries to, jointly and severally, reimburse any Holder Indemnitee for all
reasonable costs and expenses (including reasonable attorneys’ fees and expenses and any other litigation-related expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any
Action for which the Holder Indemnitee would be entitled to indemnification under the terms of this Section 5.13, or any action or proceeding arising therefrom, whether or not such Holder Indemnitee is a party thereto.
PubCo or its subsidiaries, in the defense of any Action for which a Holder Indemnitee would be entitled to indemnification under the terms of this Section 5.13, may, without the consent of such Holder Indemnitee, consent to
entry of any judgment or enter into any settlement if and only if it (i) includes as a term thereof the giving by the claimant or plaintiff therein to such Holder Indemnitee of an unconditional release from all liability with respect to such
Action, (ii) does not impose any limitations (equitable or otherwise) on such Holder Indemnitee, and (iii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Holder
Indemnitee, and provided, that the only penalty imposed in connection with such settlement is a monetary payment that will be paid in full by PubCo or its subsidiaries. 

(c) PubCo acknowledges and agrees that PubCo shall, and to the extent applicable shall cause its subsidiaries to, be fully and
primarily responsible for the payment to any Holder Indemnitee in respect of Indemnified Liabilities in connection with any Jointly Indemnifiable Claims (as defined below), pursuant to and in accordance with (as applicable) the terms of (i) the
Delaware General Corporation Law and the Organizational Documents, each as amended, (ii) any director indemnification agreement, (iii) this Investor Rights Agreement, any other agreement between PubCo or any of its subsidiaries and such
Holder Indemnitee (or its Affiliates) pursuant to which such Holder Indemnitee is indemnified, (iv) the Laws of the jurisdiction of incorporation or organization of any subsidiary of PubCo and/or (v) the certificate of incorporation,
certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation, certificate of limited partnership or other organizational or governing documents of any subsidiary of PubCo ((i) through
(v) collectively, the “Indemnification Sources”), irrespective of any right of recovery such Holder Indemnitee (or its Affiliates) may have from any corporation, limited liability company, partnership, joint venture, trust,
employee benefit plan or other enterprise (other than PubCo, any of its subsidiaries or the insurer under and pursuant to an insurance policy of PubCo or any of its subsidiaries) from whom such Holder Indemnitee may be entitled to indemnification
with respect to which, in whole or in part, PubCo or any of its subsidiaries may also have an indemnification obligation (collectively, the “Indemnitee-Related Entities”). Under no circumstance shall PubCo or any of its

  
 44 

 
subsidiaries be entitled to any right of subrogation or contribution by the Indemnitee-Related Entities and no right of advancement or recovery any Holder Indemnitee may have from the
Indemnitee-Related Entities shall reduce or otherwise alter the rights of such Holder Indemnitee or the obligations of PubCo or any of its subsidiaries under the Indemnification Sources. In the event that any of the Indemnitee-Related Entities shall
make any payment to any Holder Indemnitee in respect of indemnification with respect to any Jointly Indemnifiable Claim, (x) PubCo shall, and to the extent applicable shall cause its subsidiaries to, reimburse the Indemnitee-Related Entity
making such payment to the extent of such payment promptly upon written demand from such Indemnitee-Related Entity, (y) to the extent not previously and fully reimbursed by PubCo and/or any of its subsidiaries pursuant to clause (x), the
Indemnitee-Related Entity making such payment shall be subrogated to the extent of the outstanding balance of such payment to all of the rights of recovery of the Holder Indemnitee against PubCo and/or any of its subsidiaries, as applicable, and
(z) such Holder Indemnitee shall execute all papers reasonably required and shall do all things that may be reasonably necessary to secure such rights, including the execution of such documents as may be necessary to enable the
Indemnitee-Related Entities effectively to bring suit to enforce such rights. Each of the Parties agree that each of the Indemnitee-Related Entities shall be third-party beneficiaries with respect to this Section 5.13(c),
entitled to enforce this Section 5.13(c) as though each such Indemnitee-Related Entity were a party to this Investor Rights Agreement. PubCo shall cause each of its subsidiaries to perform the terms and obligations of this
Section 5.13(c) as though each such subsidiary were a party to this Investor Rights Agreement. For purposes of this Section 5.13(c), the term “Jointly Indemnifiable Claims” shall
be broadly construed and shall include, without limitation, any Indemnified Liabilities for which any Holder Indemnitee shall be entitled to indemnification from both (1) PubCo and/or any of its subsidiaries pursuant to the Indemnification
Sources, on the one hand, and (2) any Indemnitee-Related Entity pursuant to any other agreement between any Indemnitee-Related Entity and such Holder Indemnitee (or its Affiliates) pursuant to which such Holder Indemnitee is indemnified, the
Laws of the jurisdiction of incorporation or organization of any Indemnitee-Related Entity and/or the certificate of incorporation, certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation,
certificate of limited partnership or other organizational or governing documents of any Indemnitee-Related Entity, on the other hand. 

(d) In no event shall any Holder Indemnitee be liable to PubCo or any of its subsidiaries for any act, alleged act, omission or
alleged omission that does not constitute willful misconduct or fraud of such Holder Indemnitee as determined by a final, nonappealable determination of a court of competent jurisdiction. 

(e) Notwithstanding anything to the contrary contained in this Investor Rights Agreement, for purposes of this
Section 5.13, the term Holder Indemnitees shall not include any Holder or its any of its partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents or
any of the partners, equityholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of any of the foregoing who is an officer or director of PubCo or any of its subsidiaries in such capacity
as officer or director. Such officers and directors are or will be subject to separate indemnification in such capacity through this Investor Rights Agreement and/or the certificate of incorporation or organization, bylaws or limited partnership
agreements and other instruments of PubCo and its subsidiaries. 

  
 45 

 (f) The rights of any Holder Indemnitee to indemnification pursuant to this
Section 5.13 will be in addition to any other rights any such Person may have under any other section of this Investor Rights Agreement or any other agreement or instrument to which such Holder Indemnitee is or becomes a
party or is or otherwise becomes a beneficiary or under Law or regulation or under the certificate of limited partnership, limited partnership agreement, certificate of incorporation or bylaws (or equivalent governing documents) of PubCo or any of
its subsidiaries. 
 Section 5.14 Representations and Warranties of the Parties. Each of the Parties hereby represents and
warrants to each of the other Parties as follows: 
 (a) Such Party, to the extent applicable, is duly organized or
incorporated, validly existing and in good standing under the Laws of the jurisdiction of its organization or incorporation and has all requisite organizational power and authority to conduct its business as it is now being conducted and is proposed
to be conducted. 
 (b) Such Party has the full organizational power, authority and legal right to execute, deliver and
perform this Investor Rights Agreement. The execution, delivery and performance of this Investor Rights Agreement have been duly authorized by all necessary organizational action, corporate or otherwise, of such Party. This Investor Rights Agreement
has been duly executed and delivered by such Party and constitutes its, his or her legal, valid and binding obligation, enforceable against it, him or her in accordance with its terms, subject to applicable bankruptcy, insolvency and similar Laws
affecting creditors’ rights generally. 
 (c) The execution and delivery by such Party of this Investor Rights
Agreement, the performance by such Party of its, his or her obligations hereunder by such Party does not and will not violate (i) in the case of Parties who are not individuals, any provision of its
by-laws, charter, articles of association, partnership agreement or other similar organizational document, (ii) any provision of any material agreement to which it, he or she is a Party or by which it, he
or she is bound or (iii) any Law, rule, regulation, judgment, order or decree to which it, he or she is subject. 
 (d)
Such Party is not currently in violation of any Law, rule, regulation, judgment, order or decree, which violation could reasonably be expected at any time to have a material adverse effect upon such Party’s ability to enter into this Investor
Rights Agreement or to perform its, his or her obligations hereunder. 
 (e) There is no pending legal action, suit or
proceeding that would materially and adversely affect the ability of such Party to enter into this Investor Rights Agreement or to perform its, his or her obligations hereunder. 

  
 46 

 Section 5.15 No Third Party Liabilities. This Investor Rights Agreement may only
be enforced against the named parties hereto. All claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to any of this Investor Rights Agreement, or the negotiation, execution or performance of this
Investor Rights Agreement (including any representation or warranty made in or in connection with this Investor Rights Agreement or as an inducement to enter into this Investor Rights Agreement), may be made only against the Persons that are
expressly identified as parties hereto, as applicable; and no past, present or future direct or indirect director, officer, employee, incorporator, member, partner, stockholder, Affiliate, portfolio company in which any such Party or any of its
investment fund Affiliates have made a debt or equity investment (and vice versa), agent, attorney or representative of any Party hereto (including any Person negotiating or executing this Investor Rights Agreement on behalf of a Party hereto),

this Investor Rights Agreement, or the negotiation, execution or performance of this Investor Rights Agreement (including a representation or warranty made in or in connection with this Investor Rights Agreement or as an inducement to enter into
this Investor Rights Agreement). 
 Section 5.16 Legends. Without limiting the obligations of PubCo set forth in
Section 3.11, each of the Holders acknowledges that (i) no Transfer, hypothecation or assignment of any Registrable Securities Beneficially Owned by such Holder may be made except in compliance with applicable federal
and state securities Laws and (ii) PubCo shall (x) place customary restrictive legends on the certificates or book entries representing the Registrable Securities subject to this Investor Rights Agreement and (y) remove such
restrictive legends at the time the applicable Transfer and other restrictions contemplated thereby are no longer applicable to the Registrable Securities represented by such certificates or book entries. 

Section 5.17 Adjustments. If there are any changes in the Common Stock as a result of stock split, stock dividend, combination or
reclassification, or through merger, consolidation, recapitalization or other similar event, appropriate adjustment shall be made in the provisions of this Investor Rights Agreement, as may be required, so that the rights, privileges, duties and
obligations under this Investor Rights Agreement shall continue with respect to the Common Stock as so changed.
