REGISTRATIONS AND OFFERINGS 

2.1 Shelf Registration. 

2.1.1 Filing. Within thirty (30) calendar days following the Closing Date, the Company shall submit to or file with the Commission
a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”) or a Registration Statement for a Shelf Registration on Form
S-3 (the “Form S-3 Shelf”), if the Company is then eligible to use a Form S-3 Shelf, in each case,
covering the resale of all the Registrable Securities (determined as of two (2) business days prior to such submission or filing) on a delayed or continuous basis and shall use its commercially reasonable efforts to have such Shelf declared
effective as soon as practicable after the submission or filing thereof, but no later than the earlier of (a) the ninetieth (90th) calendar day following the submission or filing date thereof
if the Commission notifies the Company that it will “review” the Registration Statement and (b) the tenth (10th) business day after the date the Company is notified (orally or in
writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review. Such Shelf shall provide for the resale of the Registrable Securities included therein
pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the Commission such
amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in
compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially
reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration Statement) to a Form S-3 Shelf as soon as practicable after the Company is
eligible to use Form S-3. The Company’s obligation under this Section 2.1.1, shall, for the avoidance of doubt, be subject to Section 3.4. 

2.1.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while
Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under
the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably
practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional 

  
 7 

 
registration statement as a Shelf Registration (a “Subsequent Shelf Registration Statement”) registering the resale of all Registrable Securities (determined as of two
(2) business days prior to such filing). If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration Statement 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 Statement shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the
Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration
Statement continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any
Registrable Securities. Any such Subsequent Shelf Registration Statement shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration
Statement shall be on another appropriate form. The Company’s obligation under this Section 2.1.2, shall, for the avoidance of doubt, be subject to Section 3.4. 

2.1.3 Additional Registrable Securities. Subject to Section 3.4, in the event that any Holder holds
Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon written request of the Sponsor, a ProKidney Holder, an Investor Stockholder, a Director Holder or an Advisor Holder, shall use commercially
reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, any then available Shelf (including by means of a post-effective amendment) or by filing a Subsequent Shelf Registration
Statement and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration Statement shall be subject to the terms hereof; provided, however, that the Company shall only be
required to cause such Registrable Securities to be so covered twice per calendar year for each of the Sponsor, each ProKidney Holder, each Investor Stockholder, each Director Holder and each Advisor Holder; provided, further, that
prior to making such filing with respect to any written request by a Holder, the Company shall notify the other Holders and provide such other Holders a reasonable opportunity to include additional Registrable Securities held by such other Holders
in such filing. 
 2.1.4 Requests for Underwritten Shelf Takedowns. Subject to Section 3.4, at any time and
from time to time when an effective Shelf is on file with the Commission, the Sponsor, an Investor Stockholder or a ProKidney Holder (any of the Sponsor, an Investor Stockholder or a ProKidney Holder being, in such case, a “Demanding
Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that
the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder, either individually or together with other Demanding Holders, with a
total offering price reasonably expected to exceed, in the aggregate, $50.0 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company,
which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Underwriters for such offering (which shall consist of one or more
reputable nationally recognized investment banks) shall be selected by the majority-in-interest of the Demanding Holders, subject to the Company’s prior approval
(which shall not be 

  
 8 

 
unreasonably withheld, conditioned or delayed). The Sponsor, an Investor Stockholder and a ProKidney Holder may each demand not more than (i) one (1) Underwritten Shelf Takedown pursuant to
this Section 2.1.4 within any six (6) month period or (ii) two (2) Underwritten Shelf Takedowns pursuant to this Section 2.1.4 in any twelve (12) month period. Notwithstanding
anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such
offering. 
 2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown,
in good faith, advises the Company, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Holders”) (if any) in writing
that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Class A Common Stock or other equity securities that the Company
desires to sell and the shares of Class A Common Stock or other equity securities, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who
desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability
of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, before including
any shares of Class A Common Stock or other equity securities proposed to be sold by Company or by other holders of Class A Common Stock or other equity securities, the Registrable Securities of the Demanding Holders and the Requesting
Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable
Securities that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf takedown) that can be sold without exceeding the Maximum Number of Securities. 

2.1.6 Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing
such Underwritten Shelf Takedown, any Demanding Holder initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a
“Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Underwritten Shelf Takedown; provided that the Sponsor, an Investor Stockholder or a ProKidney
Holder may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by the Sponsor, the Investor
Stockholders, the ProKidney Holders or any of their respective Permitted Transferees, as applicable. If withdrawn by a Demanding Holder, the Sponsor, an Investor Stockholder or a ProKidney Holder may elect to continue an Underwritten Shelf Takedown
pursuant to the proviso in the immediately preceding sentence and such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown demanded by the Sponsor, such Investor Stockholder or such ProKidney Holder, as applicable, for
purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other 

  
 9 

 
Holders that had elected to participate in such Shelf Takedown and shall not include the Registrable Securities of such withdrawing Demanding Holder in the applicable registration and such
Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement). Notwithstanding anything to the contrary in this Agreement, the Company shall be
responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6. 

2.2 Piggyback Registration. 

2.2.1 Piggyback Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a
registered offering of, or if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible,

Section 2.1), other than a Registration Statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration

not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus

of distribution thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for

a Demanding Holder, whose right to withdraw from an Underwritten Shelf Takedown, and related obligations, shall be governed by Section 2.1.6) shall have the right to withdraw from a Piggyback Registration for any or no
reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the
Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration, the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such
Piggyback Registration used for marketing such transaction. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons or entities pursuant to separate written contractual obligations) may
withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration (which, in no circumstance, shall include a Shelf or other Registration pursuant to Section 2.1) at any time prior to
the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its
withdrawal under this Section 2.2.3. 
 2.2.4 Unlimited Piggyback Registration Rights. For purposes of
clarity, subject to Section 2.1.6, any Piggyback Registration effected pursuant to Section 2.2 shall not be counted as a demand for an Underwritten Shelf Takedown under
Section 2.1.4. 
 2.3 Market Stand-off. In connection with any
Underwritten Offering of equity securities of the Company pursuant to this Agreement (other than a Block Trade), each participating Holder and each other Holder who, together with its affiliates, beneficially owns greater than five percent (5%) of
the outstanding shares of Class A Common Stock in the aggregate, agrees that it shall not Transfer any shares of Common Stock or other equity securities of the Company (other than those included in such offering pursuant to this Agreement),
without the prior written consent of the Company, during the ninety (90)-day period (or such shorter time agreed to by the managing Underwriters) beginning on the date of pricing of such offering, except as
expressly permitted by such lock-up agreement or in the event the managing Underwriters otherwise agree by written consent. Each such Holder agrees to execute a customary
lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Holders ).

 2.4 Block Trades. 

2.4.1 Notwithstanding any other provision of this Article II, but subject to Section 3.4, at any time and from
time to time when an effective Shelf is on file with the Commission, if a Demanding Holder wishes to engage in an underwritten registered offering not involving a “roadshow,” i.e., an offering commonly known as a “block trade” (a
“Block Trade”), with a total offering price reasonably expected to exceed, in the aggregate, either (x) $25.0 million or (y) all remaining Registrable Securities held by the Demanding Holder, then such
Demanding Holder shall notify the Company of its request to engage in a Block Trade and, subject to Section 3.1.8 or the waiver thereof by such Demanding Holder, the Company shall as expeditiously as possible use its
commercially reasonable efforts to facilitate such Block Trade; provided that such Demanding Holder shall use commercially reasonable efforts to work with the Company and any Underwriters prior to making such request in order to facilitate
preparation of the registration statement, prospectus and other offering documentation related to the Block Trade. 
 2.4.2 Prior to the
filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade or the issuance of a press release by the applicable Demanding Holder or by the Company with respect thereto, the Demanding
Holders initiating such Block Trade shall have the right to submit a Withdrawal Notice to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to the contrary in this
Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Block Trade prior to its withdrawal under this Section 2.4.2. 

2.4.3 Notwithstanding anything to the contrary in this Agreement, Section 2.2 shall not apply to a Block Trade
initiated by a Demanding Holder pursuant to this Agreement. 
 2.4.4 The Demanding Holder in a Block Trade shall have the right to select the
Underwriters for such Block Trade (which shall consist of one or more reputable nationally recognized investment banks). 
 2.4.5 A Holder in
the aggregate may demand no more than two (2) Block Trades per year pursuant to this Section 2.4. For the avoidance of doubt, any Block Trade effected pursuant to this Section 2.4 shall not be
counted as a demand for an Underwritten Shelf Takedown pursuant to Section 2.1.4. 
 ARTICLE III

reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 
 3.1.8 at
least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (or such shorter period of time as may be (a) necessary in order to comply with

customarily included in such opinions and negative assurance letters; 
 3.1.13 in an Underwritten Offering, enter into an underwriting
agreement in form, scope and substance as is customary in underwritten offerings and in connection therewith, (A) make representations and warranties to the Holders of such Registrable Securities and the Underwriters, if any, with respect to
the business of the Company and its subsidiaries, and the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance and scope as are customarily made by
issuers in underwritten offerings, and, if true, confirm the same if and when requested, (B) include in the underwriting agreement indemnification provisions and procedures substantially to the effect set forth in Article IV hereof with
respect to the Underwriters and all parties to be indemnified pursuant to said Article except as otherwise agreed by the majority-in-interest of the participating

 3.1.14 in the event of any Underwritten Offering or sale by a
broker, placement agent or sales agent pursuant to such Registration, enter into and perform its obligations under an underwriting or other purchase or sales agreement, in usual and customary form, with the managing Underwriter or the broker,

 3.1.15 make available to its security holders, as soon as reasonably practicable,
an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect); 

  
 16 

 3.1.16 with respect to an Underwritten Offering pursuant to
Section 2.1.4, make available senior executives of the Company to participate in meetings with analysts or customary “road show” presentations that may be reasonably requested by the Underwriter in such
Underwritten Offering; 
 3.1.17 cooperate with the participating Holders and the Underwriters, if any, to facilitate the timely preparation
and delivery of certificates (if such securities are certificated and which shall not bear any restrictive legends unless required under applicable law) representing securities sold under any Registration Statement, and enable such securities to be
in such denominations and registered in such names as such Holders or Underwriters may request and keep available and make available to the Company’s transfer agent prior to the effectiveness of such Registration Statement a supply of such
certificates (if such securities are certificated); 
 3.1.18 file the applicable Registration Statement with FINRA within three
(3) Business Days of the date such Registration Statement is filed with or submitted to the SEC, and cooperate with each participating Holder and Underwriter, if any, and their respective counsels in connection with any other filings required
to be made with FINRA; and 
 3.1.19 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably
be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration. 
 Notwithstanding the
foregoing, the Company shall not be required to provide any documents or information to an Underwriter, broker, sales agent or placement agent if such Underwriter, broker, sales agent or placement agent has not then been selected as an Underwriter,
broker, sales agent or placement agent, as applicable, with respect to the applicable Underwritten Offering or other offering involving a registration. 

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the
Holders that the Holders shall bear all Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs, transfer taxes and, other than as set forth in the definition of “Registration Expenses,” all fees and
expenses of any legal counsel representing the Holders. 
 3.3 Requirements for Participation in Registration Statement in Offerings.
Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable Registration
Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the registration and such Holder continues thereafter to withhold such information. No person or entity may participate
in any Underwritten Offering or other offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person or entity (i) agrees to sell such person’s or entity’s securities on
the basis provided in any underwriting, sales, distribution or placement arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities,
lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such underwriting, sales, distribution or placement arrangements. The
exclusion of a Holder’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration. 

  
 17 

 3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration
Rights. 
 3.4.1 Upon receipt of written notice from the Company that: (a) a Registration Statement or Prospectus contains a
Misstatement; or (b) any request by the Commission for any amendment or supplement to any Registration Statement or Prospectus or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment
to such Prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement or Prospectus, such Registration Statement or Prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make the statements therein not misleading, each of the Holders shall forthwith discontinue disposition of Registrable Securities pursuant to such Registration Statement
covering such Registrable Securities until it has received copies of a supplemented or amended Prospectus (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time
of such notice) or until it is advised in writing by the Company that the use of the Prospectus may be resumed, and, if so directed by the Company, each such Holder will deliver to the Company all copies, other than permanent file copies then in
such Holder’s possession, of the most recent Prospectus covering such Registrable Securities at the time of receipt of such notice. In the event that a Holder exercises a demand right pursuant to Section 2.1 and the
related offering is expected to, or may, occur during a quarterly earnings blackout period of the Company (such blackout periods determined in accordance with the Company’s written insider trading compliance program adopted by the Board), the
Company and such Holder shall act reasonably and work cooperatively in view of such quarterly earnings blackout period. 
 3.4.2 Subject to
Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure or
(b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control after the exercise by the Company of reasonable best efforts, or (c) in the
good faith judgment of the majority of the Board, be seriously detrimental to the Company and as a result it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice
of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the
Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection
with any sale or offer to sell Registrable Securities until such Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its
contents. 
 3.4.3 (a) During the period starting with the date thirty (30) days prior to the Company’s good faith estimate of the
date of the filing of, and ending on a date ninety (90) days after the effective date of, a Company-initiated Registration, and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the
effectiveness of 

  
 18 

 
the applicable Shelf, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4
and, (b) during the period starting with the date fifteen (15) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date forty five (45) days after the effective date of, a
Company-initiated Registration, and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf, the Company may, upon giving prompt written notice of such
action to the Holders, delay any other registered offering pursuant to Section 2.4. 
 3.4.4 The right to delay or
suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2 or a registered offering pursuant to Section 3.4.3 shall be exercised by the
Company, in the aggregate, on not more than ninety (90) consecutive calendar days, or for more than one hundred and twenty (120) total calendar days, in each case during any twelve-month period. 

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a
reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a)
or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering,
Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. The Company further covenants that it shall (i) take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act (or any successor rule then in effect) and (ii) certify to the Holders in writing that it has filed current Form 10 information with the Commission within four (4) Business Days of the Closing. Upon the
request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE IV 

INDEMNIFICATION AND CONTRIBUTION 

4.1 Indemnification. 

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors,
partners, members and agents and each person or entity who controls such Holder (within the meaning of the Securities Act), against all losses, claims, damages, liabilities and
out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees and reasonable expenses of investigation) arising out of, resulting from
or based upon any untrue or alleged untrue statement of material fact contained in or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except 

  
 19 

 
insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the
Underwriters, their officers and directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder. 

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or
cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder Information”) and, to
the extent permitted by law, shall indemnify the Company, its directors, officers, partners, members and agents and each person or entity who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees and reasonable expenses of investigation) arising out of,
resulting from or based upon any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement is contained in (or not contained in, in the case of an
omission) any Holder Information so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of
Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds actually received by such Holder from the sale of Registrable Securities pursuant to such Registration
Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the
foregoing with respect to indemnification of the Company. 
 4.1.3 Any person or entity entitled to indemnification herein shall
(i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to
indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Article IV for any legal or other expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation, unless (1) such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it which are different from or in addition to the
defenses available to such indemnifying party, (2) the indemnifying party shall have failed within a reasonable period of time to assume such defense or, having assumed such defense, has not conducted the defense of such claim actively and
diligently or (3) the named parties in any such proceeding (including any impleaded parties) include both the indemnified party and the indemnifying party and representation of both parties by the same counsel would be inappropriate

  
 20 

 
due to actual or potential differing interest between them, in which case the indemnified party shall be promptly reimbursed by the indemnifying party for the expenses incurred in connection with
retaining one separate legal counsel, in addition to any local counsel (for the avoidance of doubt, for all indemnified parties in connection therewith). If such defense is assumed, (A) the indemnifying party shall keep the indemnified party
informed as to the status of such claim at all stages thereof (including all settlement negotiations and offers), promptly submit to such indemnified party copies of all pleadings, responsive pleadings, motions and other similar legal documents and
paper received or filed in connection therewith, permit such indemnified party and their respective counsels to confer with the indemnifying party and its counsel with respect to the conduct of the defense thereof, and permit indemnified party and
its counsel a reasonable opportunity to review all legal papers to be submitted prior to their submission and (B) the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent
(but such consent shall not be unreasonably withheld). In any action hereunder as to which the indemnifying party has assumed the defense thereof with counsel satisfactory to the indemnified party, the indemnified party shall continue to be entitled
to participate in the defense thereof, with counsel of its own choice, but the indemnifying party shall not be obligated hereunder to reimburse the indemnified party for the costs thereof. No indemnifying party shall, without the prior written
consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such
settlement) or which settlement includes a statement or admission of fault, culpability or failure to act on the part of such indemnified party or which settlement does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation that shall be in form and substance satisfactory to such indemnified party. 

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities. 

4.1.5 If the indemnification provided under Section 4.1 from the indemnifying party is unavailable or insufficient to
hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in
lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and
out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other
relevant equitable considerations. The relative fault of the 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 a
material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by in the case of an omission), such indemnifying party or
indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder
under this Section 4.1.5 shall be limited to the amount of the net proceeds actually received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or
other 

  
 21 

 
liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other
fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not
be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in
this Section 4.1.5. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this
Section 4.1.5 from any person or entity who was not guilty of such fraudulent misrepresentation. 
 4.1.6 The
obligations of the parties under this Article IV shall be in addition to any liability which any party may otherwise have to any other party.

consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall
operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies
hereunder or thereunder by such party. Notwithstanding anything herein to the contrary, any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. 

5.7 Other Registration Rights. Other than as provided in the Subscription Agreements, the Company represents and warrants that no person
or entity, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration Statement filed by the Company for the
sale of securities for its own account or for the account of any other person or entity. For so long as (a) the Sponsor and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock,
the Company hereby agrees and covenants that it will not grant rights to register any Common Stock (or securities convertible into or exchangeable for Common Stock) pursuant to the Securities Act that are more favorable, pari passu or senior to
those granted to the Holders hereunder (such rights “Competing Registration Rights”) without the prior written consent of the Sponsor, (b) an Investor Stockholder and its affiliates hold, in the aggregate, at least one
percent (1%) of the outstanding shares of Class A Common Stock, the Company hereby agrees and covenants that it will not grant Competing Registration Rights without the prior written consent of such Investor Stockholder, and (c) a
ProKidney Holder and its affiliates 

  
 24 

 
hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock, the Company hereby agrees and covenants that it will not grant Competing Registration
Rights without the prior written consent of such ProKidney Holder. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of
a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. 
 5.8 Term. This
Agreement shall terminate on the earlier of (a) the tenth (10th) anniversary of the date of this Agreement and (b) with respect to any Holder, on the date that such Holder no
longer holds any Registrable Securities. The provisions of Sections 3.2 and 3.5 and Articles IV and V shall survive any termination. 

5.9 Holder Information. Each Holder agrees, if requested in writing, to represent to the Company the total number of Registrable
Securities held by such Holder in order for the Company to make determinations hereunder. 
 5.10 Additional Holders; Joinder. In addition to persons or entities who may become Holders pursuant to Section 5.2, subject to the prior written consent of each of the Sponsor, each ProKidney Holder and each
Investor Stockholder (in each case, so long as such Holder and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock), the Company may make any person or entity who acquires
Class A Common Stock or rights to acquire Class A Common Stock after the date hereof a party to this Agreement (each such person or entity, an “Additional Holder”) by obtaining an executed joinder to this Agreement
from such Additional Holder in the form of Exhibit A attached hereto (a “Joinder”). Such Joinder shall specify the rights and obligations of the applicable Additional Holder under this Agreement.
Upon the execution and delivery and subject to the terms of a Joinder by such Additional Holder, the Class A Common Stock then owned, or underlying any rights then owned, by such Additional Holder (the “Additional Holder Common
Stock”) shall be Registrable Securities to the extent provided herein and therein and such Additional Holder shall be a Holder under this Agreement with respect to such Additional Holder Common Stock. 

5.11 Severability. It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid,
prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. 

  
 25 

 5.12 Specific Performance. Each of the parties acknowledges and agrees that the other
parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, to the fullest extent permitted by law, each of
the parties agrees that, without posting bond or other undertaking, the other parties will be entitled to an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement
and the terms and provisions hereof in any action, claim or suit in addition to any other remedy to which it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect of such
breach or violation, it will not assert that the defense that a remedy at law would be adequate. 
 5.13 Entire Agreement;
Restatement. This Agreement constitutes the full and entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. Upon
the Closing, the Original RRA shall no longer be of any force or effect.

that differs from its adjusted tax basis, Carrying Value shall be adjusted by the amount of depreciation calculated for purposes of the definition of “Profits” and “Losses” rather than the amount of depreciation determined for
U.S. federal income tax purposes, and depreciation shall be calculated by reference to Carrying Value rather than tax basis once Carrying Value differs from tax basis. The Carrying Value of Partnership assets shall be increased (or decreased) to

by the General Partner pursuant to the provisions of this Agreement. As of the date of this Agreement, the only Class consists of the Common Units, which includes the Restricted Common Units. Subclasses within a Class shall not be separate

exemption with respect to its Units, not to resell any such Units and/or Class B Common Shares. For the avoidance of doubt, no Partner may Transfer all or any portion of its Units or other interest in the Partnership (or beneficial interest
therein), except as set forth in Section 10.

Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)).

with Section 9. 

  

	3.2	 Partners The respective names, addresses for notice number of Common Units and Capital
Contributions made by the Partners are as set forth in Part 2 of Schedule 1, which are fully vested at the time of issuance. Schedule 1 shall be amended from time to time by the General Partner to reflect any changes of address, the
admission of any substitute or additional Partners, any changes to the Common Units of any Partner or any changes to the information set forth thereon.

Contribution or (b) partly by way of an Equity Contribution and partly by way of an Advance provided that at least 0.01% of the Capital Contribution shall be an Equity Contribution (with up to 99.99% being an Advance). No Limited Partner shall,
while it remains a Limited Partner, be entitled directly or indirectly to draw out or receive back all or part of its Equity Contribution or Advances other than with the written agreement of the General Partner and the written consent of PubCo. The
Partners intend to treat any Advances or Equity Contributions of a Partner to the Partnership as a contribution of property to the Partnership in exchange for an interest in the Partnership pursuant to Section 721 of the Code for U.S. federal
income tax (or any similar provisions of applicable state or local tax Law) purposes and an equity contribution to the Partnership for Mexican tax purposes. 

  

	3.4	 No Additional Capital Contributions No Partner shall be required to make additional Capital
Contributions to the Partnership without the consent of such Partner or permitted to make additional capital contributions to the Partnership without the consent of the General Partner, which may be granted or withheld in its sole discretion.

PubCo (if any) or any Subsidiary of PubCo (if any)) and its representatives access thereto at any reasonable time, subject to giving 3 (three) days written notice in advance, for the purpose of inspecting same. In any event, upon request by the
Partners or within 10 (ten) days before any proposed change, the General Partner must notify the Partners of the place of maintenance of the books and records of the Partnership; 

 

	 	4.4.7	 to make distributions to the Partners in accordance with the terms of this Agreement;

 20 

 Notwithstanding any other provision of this Agreement to the contrary, without the consent
of any Partner being required, the General Partner is hereby authorized to execute, deliver and perform (x) the Tax Receivable Agreement; and (y) any amendment and any agreement, document or other instrument contemplated thereby or related
thereto. The General Partner is hereby authorized to enter into the documents described in the preceding sentence on behalf of the Partnership and the Partners, but such authorization shall not be deemed a restriction on the power of the General
Partner (or any Officer or director of the General Partner) to enter into other documents on behalf of the Partnership. Nothing set forth in this Agreement shall reduce or restrict the rights of any Person set forth in the Tax Receivable Agreement,
subject to the terms and conditions thereof. 
 The Partnership shall not enter into any contract, transaction or arrangement with any
Partner or any Connected person of a Partner, without PubCo’s prior written consent (other than contracts and dealings solely among the Partnership and its Subsidiaries). 
  

	4.5	 Maintaining the limited liability of the Limited Partners. The General Partner shall do all things and
discharge all duties or requirements of or imposed on a general partner by the Act and in particular so as to ensure, so far as it is able, that the liability of each Limited Partner is and remains limited as provided in the Act. If, for any reason,
a Limited Partner is adjudicated to have lost its limited liability status or privileges as a limited partner under the Act by reason of taking part in the management of the Partnership business or otherwise, the General Partner and each other
Limited Partner agrees and undertakes not to bring any claim itself or to support any claim by any other person that such Limited Partner should be liable for the debts or obligations of the Partnership beyond the amount it would otherwise be liable
for under section 4 of the Act if it had retained such limited liability status and privileges. 

  

	4.6	 Salary or fees. No salary or fees will be paid to the General Partner for the performance of its duties
under this Agreement.

control over the management of the business of the Partnership. Except as expressly provided herein, the Units do not confer any rights upon the Limited Partners to participate in the affairs of the Partnership described in this Agreement.

  
 21 

 SECTION 6 

DISTRIBUTIONS AND ALLOCATIONS 
  

	6.1	 Distributions 

 

	6.1.1	 Distributions Generally. The General Partner may, subject to (i) any restrictions contained in the
financing agreements to which the Partnership or any its Subsidiaries is a party, (ii) having Available Cash, and (iii) any other restrictions set forth in this Agreement, make Distributions at any time and from time to time. If any assets
of the Partnership are to be distributed in kind, they shall be distributed on the basis of their Fair Market Value. The Partners’ Capital Accounts shall be appropriately adjusted before any such distribution to reflect the increases or
decreases to the Capital Accounts which would have occurred if the property distributed in kind had been sold for its Fair Market Value by the Partnership prior to the distributions. Notwithstanding any other provision of this Agreement to the
contrary, no Distribution, Tax Distribution or other payment in respect of Units shall be required to be made to any Partner if, and to the extent that, such Distribution, Tax Distribution or other payment in respect of Units would not be permitted
under the Act or other applicable Law. 

  

	6.1.2	 Operating Distributions. The General Partner, in its sole discretion, may authorize Distributions (to
the extent of Available Cash) by the Partnership to the Partners at any time and from time to time. All Distributions by the Partnership (other than those made in connection with a Liquidity Event pursuant to Section 6.2)
shall be made or allocated to holders of Participating Units pro rata based on the number of Participating Units held by each such holder. 

  

	6.1.3	 Restricted Common Unit Distributions. No Restricted Common Unit shall be entitled to
receive any Distributions pursuant to Section 6.1.2 or Section 6.2 unless and until a Vesting Event has occurred with respect to such Restricted Common Unit (and then only with respect to periods
following such Vesting Event). Notwithstanding anything to the contrary herein, Restricted Common Units shall not be entitled to any “catch up” distributions in respect of periods prior to such Vesting Event. 

 

	6.1.4	 Tax Distributions. 

(a) Partner’s Required Tax Distribution With respect to each Partner, the Partnership shall calculate
the excess of (x)(A) the Income Amount allocated or allocable to such Partner for the Tax Estimation Period in question and for all preceding Tax Estimation Periods, if any, within the taxable year containing such Tax Estimation Period multiplied by
(B) the Assumed Tax Rate over (y) the aggregate amount of all prior Tax Distributions in respect of such taxable year and any Distributions made to such Partner pursuant to Section 6.1.2,
Section 6.1.3 or Section 6.2, with respect to the Tax Estimation Period in question and any previous Tax Estimation Period falling in the taxable year containing the applicable Tax Estimation Period
referred to in (x)(A) (the amount so calculated pursuant to this sentence is herein referred to as a “Partner’s Required Tax Distribution”); provided, however, that the General Partner may make adjustments in its
reasonable discretion to reflect transactions occurring during the taxable year; provided, further, that if the amount of a Tax Distribution actually made with respect to a Tax Estimation Period is greater than or less than any such Partner’s
Required Tax Distribution that would have been made under this Section 6.1.4(a) for such period based on subsequent tax information and assuming no limitations based on prohibitions under applicable Law, Available Cash, or
insolvency (such limitations, the “Liquidity Limitations”) (e.g., because the estimated Tax Distribution for a Tax Estimation Period was greater than or less than the amount calculated based on actual taxable income for such Tax
Estimation Period or because such Tax 

  
 22 

 
Distribution would have rendered the Partnership insolvent), then, for subsequent Tax Estimation Periods, the General Partner shall, subject to the Liquidity Limitations, cause the Partnership to
adjust the next Partner’s Required Tax Distribution downward (but not below zero) or upward (but the resulting Tax Distribution shall in all cases remain pro rata in accordance with each Partner’s Common Percentage Interest) to
reflect such excess or shortfall; provided, further, with respect to PubCo and its wholly owned Subsidiaries, the Partner’s Required Tax Distribution for any Tax Estimation Period shall be an amount sufficient for PubCo and its wholly owned
Subsidiaries to receive a Distribution pursuant to Section 6.1.1 and this Section 6.1.4 sufficient to enable PubCo and its wholly owned Subsidiaries to meet (i) their U.S. federal, state and local and
non-U.S. tax obligations and (ii) their obligations under the Tax Receivable Agreement for such Tax Estimation Period (but the resulting Tax Distribution shall in all cases remain pro rata in
accordance with each Partner’s Common Percentage Interest). For purposes of this Agreement, the “Income Amount” for a Tax Estimation Period shall equal, with respect to any Partner, the net taxable income (or, if applicable,
gross taxable income, except to the extent offset by items of loss thereof) of the Partnership allocated or allocable to such Partner for such Tax Estimation Period (excluding any compensation paid to a Partner but taking into account any corrective
allocations made pursuant to Section 7.4.10 or Section 7.4.12). For purposes of computing the Income Amount, the taxable income shall be determined by including (i) any special adjustments of
tax items required as a result of any election under Section 754 of the Code, including adjustments required by Sections 734 and 743 of the Code, and (ii) adjustments to taxable income in respect of Section 704(c) of the Code
(including “reverse Section 704(c) allocations”). For the avoidance of doubt, taxable income will include any amounts required to be included in taxable income by a Partner as a result of ownership by the
Partnership of an entity classified as a: (i) “passive foreign investment company” within the meaning of Section 1297 of the Code (including by reason of a “qualifying electing fund” election or a mark-to-market election) or (ii) “controlled foreign corporation” within the meaning of Section 957 of the Code in which a Partner (or any of its direct or
indirect owners) could be a “United States shareholder” for U.S. federal income tax purposes. 
 (b) Timing of
Tax Distributions At least five (5) days before the quarterly due date for payment of estimated tax payments by corporations or individuals (whichever is earlier) on a calendar year under the Code, the Partnership shall distribute (to the
extent of Available Cash and unless prohibited by applicable Law or by any restrictions applicable to tax distributions contained in the Partnership’s or its Subsidiaries’ then applicable bank financing agreements by which the Partnership
or its Subsidiaries are bound) to the Partners pro rata in accordance with their Common Percentage Interest), an aggregate amount of cash sufficient to provide each such Partner with a Distribution at least equal to such Partner’s
Required Tax Distribution (with amounts distributed pursuant to this Section 6.1.4, “Tax Distributions”). Notwithstanding anything to the contrary contained in this Agreement, (i) the General Partner shall make, in its
reasonable discretion, equitable adjustments (downward (but not below zero) or upward) to the Partners’ Required Tax Distributions (but the resulting Tax Distribution shall in all cases remain pro rata in accordance with each
Partner’s Common Percentage Interest) to take into account increases or decreases in the number of Common Units held by each Partner during the relevant period (including as a result of conversion of any Restricted Common Units into Common
Units in connection with the occurrence of a Vesting Event); provided that, no such adjustments shall be made that would have a material adverse effect on the Continuing Partners without the Continuing Partner Representative’s prior written
consent (which consent shall not be unreasonably withheld, conditioned, or delayed), and (ii) no Tax Distributions (or downward (but not below zero) or upward adjustment to any Tax Distributions) shall be made other than on a pro rata
basis in proportion to the Partners’ respective number of Common Units). Any Tax Distributions shall be treated in all respects as advances against future Distributions pursuant to Section 6.1.2 and Section 6.2 and shall be treated
for all purposes of this Agreement as having been paid pursuant to Section 6.1.2 or Section 6.2, as applicable. 

  
 23 

 (c) No Tax Distributions for Covered Transactions Notwithstanding
anything to the contrary herein, no Tax Distributions will be required to be made with respect to items arising with respect to any Covered Transaction, provided that any unpaid Tax Distributions with respect to any Tax Estimation Period, or portion
thereof, ending before a Covered Transaction shall continue to be required to be paid prior to any Distributions being made under Section 6.1.2 and Section 6.2. 
  

	6.2	 Liquidation Distribution All Distributions by the Partnership, and all proceeds (whether received
by the Partnership or directly by the Partners) in connection with dissolution of the Partnership shall be made or allocated among the holders of Participating Units pro rata based on the number of Participating Units held by each such
holder.  

  

	6.3	 Limitations on Distribution Notwithstanding any provision to the contrary contained in this
Agreement, the General Partner shall not make a Distribution to any Partner if such Distribution would violate the Act or other applicable Law. 

  

	6.4	 Use of Distribution Funds by PubCo PubCo shall use Distributions received from the
Partnership for payment of taxes, obligations under the Tax Receivable Agreement, liabilities or expenses, to loan funds to the Partnership in accordance with this Agreement, for the payment of dividends to its shareholders or for other general
corporate purposes as determined in the sole discretion of the PubCo; provided that, PubCo may not use such Distributions to acquire any Units, except as otherwise provided in Section 9.5. 

 

	6.5	 Distributions to the General Partner Notwithstanding any other provision of this Agreement, the General
Partner shall be allocated an amount equal to a 0.000001% share of profits and losses of the Partnership, up to a maximum allocated profit or loss of $10 per year, and the aggregate of its reasonable vouched expenses. The Available Cash available
for distribution to the Limited Partners shall be determined after reserving an amount of Available Cash equal to any profits so allocated to the General Partner (after taking into account any allocated losses), which may be distributed by the
Partnership to the General Partner any time after 180 days following the end of each Fiscal Year. Other than as specified in this Section 6.5 the General Partner shall have no entitlement to participate in any Distribution.

 SECTION 7 

CAPITAL ACCOUNTS; TAX ALLOCATIONS; TAX MATTERS 
  

	7.1	 Capital Contributions Made Prior to the Effective Date The Continuing Partners have made, prior to the
date hereof, Capital Contributions and, in exchange, the Continuing Partners have been allocated the number of Common Units as specified in Schedule 1 hereto. 

 

	7.2	 Capital Accounts. 

 

	7.2.1	 Partner Capital Accounts A separate capital account (a “Capital Account”) shall be
established and maintained for each Partner in accordance with the provisions of Treasury Regulations Section 1.704-1(b)(2)(iv) and this Section 7.2.1. The Partnership may adjust the Capital Accounts
of its Partners to reflect revaluations of the property of any Subsidiary of the Partnership that is treated as a partnership (or entity disregarded from a partnership) for U.S. federal income tax purposes. The Capital Account of each Partner shall
be credited with such 

  
 24 

	 	
Partner’s Capital Contributions, if any, all Profits allocated to such Partner pursuant to Section 7.3 and any items of income or gain which are specially allocated pursuant to
Section 7.4; and shall be debited with all Losses allocated to such Partner pursuant to Section 7.3, any items of loss or deduction of the Partnership specially allocated to such Partner pursuant to Section 7.4, and all cash and the
Carrying Value of any property (net of liabilities assumed by such Partner and the liabilities to which such property is subject) distributed by the Partnership to such Partner. Any references in any section of this Agreement to the Capital Account
of a Partner shall be deemed to refer to such Capital Account as the same may be credited or debited from time to time as set forth above. In the event of any Transfer of any interest in the Partnership in accordance with the terms of this
Agreement, the Transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred interest. The General Partner shall also (i) make any adjustments that are necessary or appropriate in accordance with
Treasury Regulations Section 1.704-1(b)(2)(iv)(q) and (ii) make any appropriate modifications for unanticipated events that might otherwise cause this Agreement not to comply with Treasury
Regulations Section 1.704-1(b), provided that, to the extent that any such adjustment is inconsistent with any other provisions of this Agreement and would have a disproportionate (compared to PubCo) and
material adverse effect on any Partner, such adjustment shall require the consent of such Partner. For Mexican tax purposes, the applicable rules shall be article 4-A, and related provisions of the Mexican
income tax law. 

  

	7.2.2	 Loans to the Partnership If a Partner advances or lends any funds to the Partnership (other than, for
the avoidance of doubt, any Advance made as part of a Capital Contribution), the amount of any such loan shall not increase the Partner’s Capital Account or affect in any way his, her or its share, as a Partner, in the profits, losses or
distributions of the Partnership, but shall be a debt due from the Partnership. 

  

	7.3	 Allocations of Profits and Losses Except as otherwise provided in this Agreement, Profits
and Losses (and, to the extent necessary, individual items of income, gain or loss or deduction of the Partnership) shall be allocated in a manner such that the Capital Account of each Partner after giving effect to the special allocations set forth
in Section 7.4 is, as nearly as possible, equal (proportionately) to (i) the Distributions that would be made pursuant to Section 6.2 if the Partnership were dissolved, its affairs wound up and its assets sold for cash equal to their
Carrying Value, all Partnership liabilities were satisfied in cash in accordance with their terms (limited with respect to each nonrecourse liability to the Carrying Value of the assets securing such liability) and all remaining or resulting cash
was distributed to the Partners, minus (ii) such Partner’s share of Partnership Minimum Gain and Partnership Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets. Notwithstanding the foregoing, the
General Partner shall make such adjustments to Capital Accounts as it determines in its reasonable discretion to be appropriate to ensure allocations are made in accordance with a Partner’s interest in the Partnership. 

 

	7.4	 Special Allocations Notwithstanding any other provisions in this Section 7:

  

	7.4.1	 Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain (determined in
accordance with the principles of Treasury Regulations Section 1.704-2(d)) during any Partnership taxable year, the Partners shall be specially allocated items of Partnership income and gain for such year
(and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Section 1.704-2(g). The items to be
so allocated shall be determined in accordance with Treasury Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 7.4.1 is intended to comply with the
minimum gain chargeback requirements in Treasury Regulations Section 1.704-2(f) shall be interpreted consistently therewith, including that no chargeback shall be required to the extent of the exceptions
provided therein. 

  
 25 

	7.4.2	 Nonrecourse Debt Minimum Gain Chargeback. If there is a net decrease in Partner Nonrecourse Debt Minimum
Gain (determined in accordance with the principles of Treasury Regulations Section 1.704-2(i)) during any Partnership taxable year, the Partners shall be specially allocated items of Partnership income
and gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations
Section 1.704-2(i)(5). The items to be so allocated shall be determined in accordance with Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 7.4.2 is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Section 1.704-2(i)(4) and shall be
interpreted consistently therewith, including that no chargeback shall be required to the extent of the exceptions provided therein. 

  

	7.4.3	 Qualified Income Offset. If any Partner unexpectedly receives any adjustments, allocations, or
distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner
sufficient to eliminate the deficit balance in such Partner’s Adjusted Capital Account Balance created by such adjustments, allocations or distributions as promptly as possible; provided that, an allocation pursuant to this Section 7.4.3
shall be made only to the extent that a Partner would have a deficit Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Section 7 have been tentatively made as if this Section 7.4.3 were
not in this Agreement. This Section 7.4.3 is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith. 

 

	7.4.4	 Gross Income Allocation. If any Partner has a deficit Capital Account at the end of any Fiscal Year
which is in excess of the sum of (i) the amount such Partner is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate
sentences of Treasury Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be specially allocated items of Partnership income and gain in
the amount of such excess as quickly as possible; provided that, an allocation pursuant to this Section 7.4.4 shall be made only if and to the extent that a Partner would have a deficit Capital Account in excess of such sum after all other
allocations provided for in this Section 7 have been tentatively made as if Section 7.4.3 and this Section 7.4.4 were not in this Agreement. 

  

	7.4.5	 Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners
holding Common Units in accordance with their respective Common Percentage Interest. 

  

	7.4.6	 Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated
to the Partner who bears the economic risk of loss with respect to the liability to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulations
Section 1.704-2(i)(1). 

  

	7.4.7	 Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any
Partnership Asset, pursuant to Code Section 734(b) or Section 743(b) is required, pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) or
Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a Distribution to a Partner in complete liquidation of such Partner’s interest in the
Partnership, the amount of such adjustment 

  
 26 

	 	
to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be
specially allocated to the Partners in accordance with their interests in the Partnership in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Partner to whom such
Distribution was made in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies. 

  

	7.4.8	 Ameliorative Allocations. Any special allocations of income or gain pursuant to Sections 7.4.1, 7.4.2,
7.4.3 or 7.4.4 hereof shall be taken into account in computing subsequent allocations pursuant to Section 7.3 and this Section 7.4.8, so that the net amount of any items so allocated and all other items allocated to each Partner shall, to
the extent possible, be equal to the net amount that would have been allocated to each Partner if such allocations pursuant to Sections 7.4.1, 7.4.2, 7.4.3 or 7.4.4 had not occurred. 

 

	7.4.9	 Allocations Relating to Taxable Issuance of Partnership Units. Any income, gain, loss, or deduction
realized as a direct or indirect result of the issuance of Units by the Partnership to a Partner (the “Issuance Items”) shall be allocated among the Partners so that, to the extent possible, the net amount of such Issuance Items,
together with all other allocations under this Agreement to each Partner shall be equal to the net amount that would have been allocated to each such Partner if the Issuance Items had not been realized. The forfeiture allocations described in
Proposed Regulations Section 1.704-1(b)(4)(xii)(C) (2005), and the allocations to which they relate, shall be treated as Issuance Items. 

 

	7.4.10	 Restricted Common Units. Notwithstanding anything to the contrary contained in this Agreement,
(1) no allocation (of Profits or Losses or otherwise) shall be made in respect of any Restricted Common Units in determining Capital Accounts unless and until such Restricted Common Units are converted into Common Units upon the occurrence of a
Vesting Event and (2) in the event the Carrying Value is adjusted pursuant to clause (g) of the definition of Carrying Value, any Profits or Losses resulting from such adjustment shall, in the manner reasonably determined by the General
Partner, be allocated among the Partners (including the Partners who held the Restricted Common Units giving rise to such adjustment) such that the Capital Account balance relating to each Common Unit (including such Restricted Common Units that
have been converted into Common Units) is equal in amount immediately after making such allocation in accordance with principles similar to those set forth in Treasury Regulations
Section 1.704-1(b)(2)(iv)(s). In connection with and following the occurrence of each Vesting Event, Tolerantia, LLC may require that the Partnership either (A) allow it or its Affiliate to subscribe
for and purchase $10,000 worth of Common Units from the Partnership (or a larger amount with the consent of the General Partner) rounded down to the nearest Common Unit for cash consideration priced using the 5 Day VWAP (at which time Carrying Value
shall be adjusted pursuant to clause (a) of the definition of Carrying Value); or (B) redeem Tolerantia, LLC of $10,000 worth of its Common Units (or a larger amount with the consent of the General Partner) rounded down to the nearest
Common Unit for cash consideration priced using 5 Day VWAP (at which time Carrying Value shall be adjusted pursuant to clause (b) of the definition of Carrying Value). 

 

	7.4.11	 Forfeiture Allocation. In the event that the Units of any Partner are forfeited, then for the fiscal
year of such forfeiture or other period (as determined by the General Partner): 

 (i) items of income, gain, loss, and
deduction shall be excluded from the calculation of Profits and Losses and shall be specially allocated to the Partner whose Units have been forfeited so as to cause such Partner’s Capital Account to equal such Partner’s Distribution
entitlements under Section 6.1 after giving effect to the adjustment in the Partner’s Common Percentage Interest resulting from the applicable forfeiture; and 

  
 27 

 (ii) the General Partner may elect to apply another allocation or Capital Account adjustment
method to a Unit forfeiture as it reasonably deems appropriate in lieu of the method set forth in Section 7.4.11(i). 
  

	7.4.12	 Non-compensatory Options. If, as a result of an exercise of a non-compensatory option to acquire an interest in the Partnership, a Capital Account reallocation is required under Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(3),
the Partnership shall make corrective allocations pursuant to Treasury Regulations Section 1.704-1(b)(4)(x). 

  

	7.5	 Tax Allocations For U.S. federal income tax purposes, each item of income, gain, loss and
deduction of the Partnership shall be allocated among the Partners in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that, in the case of any asset
the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated solely for income tax purposes in accordance with the principles of
Sections 704(b) and (c) of the Code (in any manner determined by the General Partner and permitted by the Code and Treasury Regulations; provided that, except as otherwise provided in this Section 7.5, the prior written consent of the
Requisite Continuing Partners shall be required for use of any method other than the traditional method (without curative allocations) described in Treasury Regulation Section 1.704-3(b)) so as to take
account of the difference between Carrying Value and adjusted basis of such asset; provided, further, that with respect to the reverse Section 704(c) allocations resulting from the adjustment that occurred immediately prior to the investment by
PubCo in connection with the Existing Partnership Agreement and the subsequent purchase of interests in the Partnership by PubCo pursuant to the Business Combination Agreement, the Partnership shall adopt the “remedial allocation method”
described in Treasury Regulation Section 1.704-3(d) (unless otherwise consented to by PubCo), for making such allocations. Notwithstanding the foregoing, the General Partner shall make such allocations
for tax purposes as it determines in its reasonable discretion, subject to, for so long as the Continuing Partners collectively own at least 10% of the Units, the prior written consent, not to be unreasonably withheld, conditioned or delayed, of the
Requisite Continuing Partners, to be appropriate to ensure allocations are made in accordance with a Partner’s interest in the Partnership. 

  

	7.6	 Tax Advances If the Partnership or any other Person in which the Partnership holds an interest is
required by Law to withhold or to make tax payments on behalf of or with respect to any Partner, or the Partnership is subjected to tax itself (including any amounts withheld from amounts directly or indirectly payable to the Partnership or to any
other Person in which the Partnership holds an interest) by reason of the status of any Partner as such or that is specifically attributable to a Partner (including U.S. federal, state, or local or non-U.S.
withholding, personal property, unincorporated business or other taxes, the amount of any taxes arising under the Partnership Audit Provisions, the amount of any taxes imposed under Code Section 1446(f), and any interest, penalties, additions
to tax, and expenses related to any such amounts) (“Tax Advances”), the General Partner may cause the Partnership to withhold such amounts and cause the Partnership to make such tax payments as so required. All Tax Advances made on
behalf of a Partner shall be repaid by reducing the amount of the current or next succeeding Distribution or Distributions which would otherwise have been made to such Partner or, if such Distributions are not sufficient for that purpose, by so
reducing the proceeds of liquidation otherwise payable to such Partner. For all purposes of this Agreement, such Partner shall be 

  
 28 

	 	
treated as having received the amount of the Distribution that is equal to the Tax Advance. Each Partner hereby agrees to indemnify and hold harmless the Partnership and the other Partners from
and against any liability (including any liability for taxes, penalties, additions to tax or interest other than any penalties, additions to tax or interest imposed as a result of the Partnership’s failure to withhold or make a tax payment on
behalf of such Partner which withholding or payment is required pursuant to applicable Law) with respect to income attributable to or Distributions or other payments to such Partner. For the avoidance of doubt, any income taxes, penalties, additions
to tax and interest payable by the Partnership or any fiscally transparent entity in which the Partnership owns an interest shall be treated as specifically attributable to the Partners and shall be allocated among the Partners such that the burden
of (or any diminution in distributable proceeds resulting from) any such amounts is borne by those Partners to whom such amounts are specifically attributable (whether as a result of their status, actions, inactions or otherwise, including pursuant
to an allocation made under Section 7.7), in each case as reasonably determined by the General Partner. For the avoidance of doubt, any taxes, penalties, and interest payable under the Partnership Audit Provisions by the Partnership or any
fiscally transparent entity in which the Partnership owns an interest shall be treated as specifically attributable to the Partners of the Partnership, and the General Partner shall use commercially reasonable efforts to allocate the burden of (or
any diminution in distributable proceeds resulting from) any such taxes, penalties or interest to those Partners to whom such amounts are specifically attributable (whether as a result of their status, actions, inactions or otherwise), as reasonably
determined by the General Partner. 

  

	7.7	 Partnership Representative 

(a) General Partner as Partnership Representative The General Partner is hereby designated as the “partnership
representative” as that term is defined in Partnership Audit Provisions for taxable years of the Partnership beginning with the taxable year including the Effective Date. In addition, the General Partner is hereby authorized to designate or
remove any other Person as the Partnership Representative. For each Fiscal Year in which the Partnership Representative is an entity, the Partnership Representative shall appoint an individual identified by the Partnership Representative for such
Fiscal Year to act on its behalf (the “Designated Individual”) in accordance with the applicable regulations or analogous provisions of state or local Law. Each Partner hereby expressly consents to such designations and agrees to
take, and that the General Partner is authorized to take (or cause the Partnership to take), such other actions as may be necessary or advisable pursuant to Treasury Regulations or other IRS or Treasury guidance or state or local Law to cause such
designations or evidence such Partner’s consent to such designations. 
 (b) Authority of Partnership
Representative Subject to this Section 7.7, the Partnership Representative shall have the sole authority to act on behalf of the Partnership in connection with, make all relevant decisions regarding application of, and to exercise the
rights and powers provided for in the Partnership Audit Provisions, including making any elections under the Partnership Audit Provisions or any decisions to settle, compromise, challenge, litigate or otherwise alter the defense of any action, audit
or examination before the IRS or any other tax authority (each, an “Audit”), and to expend Partnership funds for professional services and other expenses reasonably incurred in connection therewith. 

  
 29 

 (c) Notice of Audits Without limiting the foregoing, the Partnership
Representative shall give prompt written notice to the Continuing Partner Representative of the commencement of any Audit of the Partnership or any of its Subsidiaries the resolution of which would reasonably be expected to have a disproportionate
(compared to PubCo) and material adverse effect on the Continuing Partners (a “Specified Audit”). The Partnership Representative shall (i) keep the Continuing Partner Representative reasonably informed of the material
developments and status of any such Specified Audit, (ii) permit the Continuing Partner Representative (or its designee) to participate (including using separate counsel), in each case at the Continuing Partner’ sole cost and expense, in
any such Specified Audit, and (iii) promptly notify the Continuing Partner Representative of receipt of a notice of a final partnership adjustment (or equivalent under applicable Laws) or a final decision of a court or IRS Independent Office of
Appeals panel (or equivalent body under applicable Laws) with respect to such Specified Audit. The Partnership Representative or the Partnership shall promptly provide the Continuing Partner Representative with copies of all material correspondence
between the Partnership Representative or the Partnership (as applicable) and any governmental entity in connection with such Specified Audit and shall give the Continuing Partner Representative a reasonable opportunity to review and comment on any
material correspondence, submission (including settlement or compromise offers) or filing in connection with any such Specified Audit. Additionally, the Partnership Representative shall not (and the Partnership shall not (and shall not authorize the
Partnership Representative to)) settle, compromise or abandon any Specified Audit in a manner that would reasonably be expected to have a disproportionate (compared to PubCo) and material adverse effect on the Continuing Partners without the
Requisite Continuing Partners’ prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned). The Partnership Representative shall obtain the prior written consent of the Requisite Continuing Partners (which
consent shall not be unreasonably withheld, delayed or conditioned) before (i) making an election under Section 6226(a) of the Code (or any analogous provision of state, local or non-U.S. Law) or
(ii) taking any material action under the Partnership Audit Provisions that would reasonably be expected to have a disproportionate (compared to PubCo) and material adverse effect on the Continuing Partners, in the case of clauses (i) and
(ii); provided that, no consent from the Requisite Continuing Partners is required in order to make an election under Section 6226(a) of the Code with respect to taxable periods that began on or before the Effective Time. 

(d) Expenses of Partnership Representative All expenses incurred by the Partnership Representative or Designated
Individual in connection with its duties as partnership representative or designated individual, as applicable, shall be expenses of the Partnership (including, for the avoidance of doubt, any costs and expenses incurred in connection with any
claims asserted against the Partnership Representative or Designated Individual, as applicable, except to the extent the Partnership Representative or Designated Individual is determined to have performed its duties in the manner described in
clauses (i) and (ii) of the final sentence of this Section 7.7(d)), and the Partnership shall reimburse and indemnify the Partnership Representative or Designated Individual, as applicable, for all such expenses and costs. Nothing herein
shall be construed to restrict the Partnership Representative or Designated Individual from engaging lawyers, accountants, tax advisers, or other professional advisers or experts to assist the Partnership Representative or Designated Individual in
discharging its duties hereunder. Neither the Partnership Representative nor Designated Individual shall be liable to the Partnership, any Partner or any Affiliate thereof for any costs or losses to any Persons, any diminution in value or any
liability whatsoever arising as a result of the performance of its duties pursuant to this Section 7.7 absent (i) willful breach of any provision of this Section 7.7 or (ii) bad faith, fraud, gross negligence or wilful misconduct
on the part of the Partnership Representative or Designated Individual, as applicable. 

  
 30 

 (e) Adherence to Business Combination Agreement The Partnership, the
Partnership Representative, and the Partners expressly agree to be bound by the terms of Section 7.6 of the Business Combination Agreement. Notwithstanding anything to the contrary contained in this Agreement, in the event of any conflict
between Section 7.6 of the Business Combination Agreement and this Agreement, Section 7.6 of the Business Combination Agreement shall control. 
  

	7.8	 Other Allocation Provisions Certain of the foregoing provisions and the other provisions of this
Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such
regulations. In addition to amendments effected in accordance with Section 14.12 or otherwise in accordance with this Agreement, Sections 7.2, 7.3 and 7.4 may also, so long as any such amendment does not materially change the relative economic
interests of the Partners, be amended at any time by the General Partner if necessary, in the opinion of tax counsel to the Partnership, to comply with such regulations or any applicable Law. 

 

	7.9	 Survival Sections 7.6 and 7.7 shall be interpreted to apply to Partners and former Partners and shall
survive the Transfer of a Partner’s Units and the termination, dissolution, liquidation and winding up of the Partnership and, for this purpose to the extent not prohibited by applicable Law, the Partnership shall be treated as continuing in
existence. 

  

	7.10	 Mexican Income Tax Law With respect to Sections 7.4.1 to 7.4.6 (inclusive), 7.4.9, 7.4.11 and 7.5, for
Mexican tax purposes, Mexican income tax law shall apply to any Partner that is resident in Mexico for tax purposes. 

  

	7.11	 Business Combination Agreement Holder Representative Matters Section 7.6(f) of the Business
Combination Agreement is hereby incorporated by reference into this Agreement and, without limiting the generality of the foregoing, each Existing Company Unitholder and Closing Company Unitholder hereby acknowledges and agrees that amounts
otherwise payable to such Existing Company Unitholder or Closing Company Unitholder hereunder may instead be remitted to the Holder Representative (as defined in the Business Combination Agreement) in the circumstances, and at the times and in the
amounts, set forth in such section of the Business Combination Agreement. 

 SECTION 8 

BOOKS OF ACCOUNT, ACCOUNTING REPORTS, TAX RETURNS, FISCAL YEAR, BANKING 

 

	8.1	 Books, Records and Reports; Information Rights. 

 

	8.1.1	 Maintenance of books and records At all times during the continuance of the Partnership, the Partnership
shall prepare and maintain separate books of account for the Partnership in accordance with GAAP. The Partnership shall keep correct and complete books and records of its accounts and transactions and minutes of the proceedings of its Partners. The
books and records of the Partnership may be in written form or in any other form which can be converted within a reasonable time into written form for visual inspection. Minutes shall be recorded in written form, but may be maintained in the form of
a reproduction. The books and records of the Partnership maintained by the General Partner and shall be available for examination by any Partner, or its duly-authorized representatives, during regular business hours, upon ten (10) Business
Days’ written notice to the General Partner, for any purpose reasonably related to the Partner’s ownership interest in the Partnership. 

  
 31 

	8.1.2	 Limited Partner Right to Agreement Each Limited Partner shall have the right to receive, for a purpose
reasonably related to such Limited Partner’s interest as a Partner in the Partnership, upon reasonable written demand stating the purpose of such demand and at such Partner’s own expense, a copy of the Certificate and this Agreement and
all amendments thereto, together with a copy of the executed copies of all powers of attorney pursuant to which the Certificate and this Agreement and all amendments thereto have been executed. 

 

	8.2	 Tax returns and tax information The General Partner shall cause to be prepared and filed all necessary
U.S. federal, state, local and non-U.S. tax returns for the Partnership, including making any tax elections. At the Partnership’s expense, the General Partner, within 120 days of the close of the Fiscal
Year, shall use commercially reasonable efforts to furnish to each Partner that was a Partner during such Fiscal Year a Schedule K-1 and such other tax information reasonably required for U.S. federal, state
and local income tax reporting purposes. The Partnership shall use commercially reasonable efforts to provide to each Person that was a Partner during the Fiscal Year (a) by May 15th, August 15th and November 15th of such Fiscal Year, with an
estimate of the taxable income, gains, deductions, losses and other items for, respectively, the first, second and third fiscal quarters that such Person will be required to include in its taxable income and (b) by March 1st of such Fiscal
Year, with an estimate of the taxable income, gains, deductions, losses and other items of such Person to be reflected on the Schedule K-1 of such Person for the prior Fiscal Year (it being understood such
estimated information is subject to change based on the final Schedule K-1 made available by the Partnership). The Partnership also shall provide the Partner with such other information as may be reasonably
requested for purposes of allowing the Partners to prepare and file their own tax returns; provided that, any costs or expenses with respect to the foregoing shall be borne by the requesting Partner. 

 

	8.3	 Tax Elections. The General Partner shall make the following elections on the appropriate tax returns and
shall not rescind them without the prior written consent of the Requisite Continuing Partners (provided that, the election described in clause (ii) below cannot be rescinded without the prior written consent of all the Partners):

  

	 	(i)	 to adopt an appropriate U.S. federal income tax method of accounting and to keep the Partnership’s books
and records on such income-tax method; 

  

	 	(ii)	 to have in effect (and to cause each direct or indirect Subsidiary that is treated as a partnership for U.S.
federal income tax purposes and over 50% owned and controlled by the Partnership to have in effect, to the extent eligible to do so) an election, pursuant to Section 754 of the Code (and any similar election for state or local tax purposes), to
adjust the tax basis of Partnership properties, for the taxable year of the Partnership that includes the Effective Date and each subsequent taxable year in which an Exchange Transaction occurs; and 

 

	 	(iii)	 any other available election that the General Partner deems appropriate; provided that, for so long as the
Continuing Partners collectively own at least 10% of the Units, the General Partner shall consult in good faith with the Continuing Partner Representative with respect to any material tax election with respect to the Partnership that could
reasonably be expected to have a disproportionate (as compared to PubCo) and material adverse effect on the Continuing Partners, and not make such election without the Requisite Continuing Partners’ prior written consent (which consent shall
not be unreasonably withheld, delayed or conditioned). 

  
 32 

 No Partner may make an election for the Partnership to be excluded from the application of
the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state Law, and no provision of this Agreement shall be construed to sanction or approve such an election. 

 

	8.4	 Confidentiality 

 

	8.4.1	 Confidential Information Each of the Partners (other than PubCo) agrees to hold the Partner’s
Confidential Information in confidence and may not disclose or use such information except as otherwise authorized separately in writing by the General Partner. “Confidential Information” as used herein includes all non-public information concerning the Partnership or its Subsidiaries including, but not limited to, ideas, financial product structuring, business strategies, innovations and materials, all aspects of the
Partnership’s business plan, proposed operation and products, corporate structure, financial and organizational information, analyses, proposed partners, software code and system and product designs, employees and their identities, equity
ownership, the methods and means by which the Partnership plans to conduct its business, all trade secrets, trademarks, tradenames and all intellectual property associated with the Partnership’s business. With respect to each Partner,

violation of this Agreement; (ii) is approved for release by written authorization of the Chief Executive Officer, Chief Financial Officer or General Counsel of the Partnership or of PubCo, or any other officer designated by the General Partner
and PubCo; (iii) is disclosed to such Partner or their representatives by a third party not, to the knowledge of such Partner, in violation of any obligation of confidentiality owed to the Partnership, PubCo or any of their respective
Subsidiaries with respect to such information; or (iv) is or becomes independently developed by such Partner or their respective representatives without use of or reference to the Confidential Information. 

 

	8.4.2	 Limited Right to Disclose Confidential Information Solely to the extent it is reasonably necessary or
appropriate to fulfil its obligations or to exercise its rights under this Agreement, each of the Partners may disclose Confidential Information to its Subsidiaries, Affiliates, partners, directors, officers, employees, counsel, advisers,
consultants, outside contractors and other agents, on the condition that such Persons keep the Confidential Information confidential to the same extent as such Partner is required to keep the Confidential Information confidential; provided
that, such Partner shall remain liable with respect to any breach of this Section 8.4 by any such Subsidiaries, Affiliates, partners, directors, officers, employees, counsel, advisers, consultants, outside contractors and
other agents (as if such Persons were party to this Agreement for purposes of this Section 8.4). 

  

	8.4.3	 Further Right to Disclose Confidential Information Notwithstanding anything herein to the contrary, each
of the Partners may disclose Confidential Information: 

 (a) to the extent that such Partner is required
by Law (by oral questions, interrogatories, request for information or documents, subpoena, civil investigative demand or similar process) to disclose any of the Confidential Information, 

(b) for purposes of reporting to its stockholders and direct and indirect equity holders (each of whom are bound by customary
confidentiality obligations) the performance of the Partnership and its Subsidiaries and for purposes of including applicable information in its financial statements to the extent required by applicable Law or applicable accounting standards; or

  
 33 

 (c) to any bona fide prospective purchaser of the equity or assets of
a Partner, or the Common Units held by such Partner (provided, in each case, that such Partner determines in good faith that such prospective purchaser would be a Permitted Transferee), or a prospective merger partner of such Partner
(provided that, (i) such Persons will be informed by such Partner of the confidential nature of such information and shall agree in writing to keep such information confidential in accordance with the contents of this Agreement and
(ii) each Partner will be liable for any breaches of this Section 8.4 by any such Persons (as if such Persons were party to this Agreement for purposes of this Section 8.4)). 

 

	8.4.4	 PubCo’s Use of Confidential Information Notwithstanding any of the foregoing, nothing in this
Section 8.4 will restrict in any manner the ability of PubCo to comply with its disclosure obligations under Law, and the extent to which any Confidential Information is necessary or desirable to disclose. 

SECTION 9 
 UNITS

  

	9.1	 Units 

  

	9.1.1	 Units in the Partnership Interests in the Partnership shall be represented by Units. At the execution of
this Agreement, the Units are comprised of only Common Units, which includes the Restricted Common Units, comprised of Series 1 RCUs, Series 2 RCUs, Series 3 RCUs, and PMEL RCUs. 

(a) Restricted Common Units In connection with the transactions contemplated by the Business Combination Agreement,
(a) each Partner that is an Earnout Participant (as defined in the Business Combination Agreement) shall be issued Series 1 RCUs, Series 2 RCUs and Series 3 RCUs, and (b) certain PMEL Post-Combination Unitholders shall be issued the PMEL
RCUs. All such Restricted Common Units shall be outstanding as of the Effective Time. Immediately following the Effective Time, no fractional Restricted Common Unit will remain outstanding and any fractional Restricted Common Unit held by a Partner
shall be rounded down to the nearest whole number. For the avoidance of doubt, the terms contained in a PMEL Award Agreement, including with respect to vesting and forfeiture, shall be read for all relevant purposes hereunder as if they were grants
of the corresponding number of PMEL RCUs into which the PMEL Interests were substituted by virtue of the Business Combination Agreement and the General Partner shall have the authority to reasonably interpret the provisions of any PMEL Award
Agreements in accordance with the foregoing principle for all purposes of this Agreement. 
 (b) Allocation of Restricted
Common Units Immediately after giving effect to the transactions contemplated by the Business Combination Agreement, each Partner holds the number of Common Units and the number of Series 1 RCUs, Series 2 RCUs, Series 3 RCUs, and PMEL RCUs set
forth opposite such Partner’s name on Schedule I attached hereto. 
  

	9.1.2	 Further Issuances Subject to Section 9.5, the General Partner in its sole discretion may establish
and issue, from time to time in accordance with such procedures as the General Partner shall determine from time to time, additional Units, in one or more classes or series of Units, or other Partnership securities, at such price, and with such
designations, preferences and relative, participating, optional or other special rights, powers and duties (which may be senior to existing Units, classes and series of Units or other Partnership securities), as shall be determined by the General
Partner without the approval of any Partner, including: 

  
 34 

 (a) the right of such Units to share in Profits and Losses or items thereof;

 (b) the right of such Units to share in Partnership Distributions; 

(c) the rights of such Units upon dissolution and winding up of the Partnership; 

(d) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem such Units (including
sinking fund provisions); 
 (e) whether such Units are issued with the privilege of conversion or exchange and, if so, the
terms and conditions of such conversion or exchange; 
 (f) the terms and conditions upon which such Units will be issued,
evidenced by certificates and assigned or transferred; 
 (g) the method for determining the Common Percentage Interest as to
such Units; 
 (h) the terms and conditions of the issuance of such Units (including the amount and form of consideration, if
any, to be received by the Partnership in respect thereof, the General Partner being expressly authorized, in its sole discretion, to cause the Partnership to issue such Units for less than Fair Market Value); and 

(i) the right, if any, of the holder of such Units to vote on Partnership matters, including matters relating to the relative
designations, preferences, rights, powers and duties of such Units; 
 provided that notwithstanding anything to the contrary in this
Agreement, no Partnership securities ranking senior to the Common Units held by PubCo (including with respect to voting, liquidation and distribution rights) shall be authorized or issued without PubCo’s prior written consent. 

Notwithstanding any other provision of this Agreement (except as set forth in the immediately preceding proviso), the General Partner in its
sole discretion, without the approval of any other Partner, is authorized to: 
 (a) issue Units or other Partnership
securities of any newly established class or any existing class to Partners or other Persons who may acquire an interest in the Partnership, including Equity Interests which constitute a “profits interest” to Persons within the meaning of
IRS Revenue Procedures 93-27 and 2001-43 and IRS Notice 2005-43 and which will be issued with the intention that under current
interpretations of the Code the recipient will not realize income upon the issuance of such Equity Interests, and that neither the Partnership nor any Partner is entitled to any deduction either immediately or through depreciation or amortization as
a result of the issuance of such Equity Interest; 
 (b) amend this Agreement to reflect the creation of any such new class,
the issuance of Units or other Partnership securities of such class, and the admission of any Person as a Partner which has received Units or other Partnership securities; and 

  
 35 

 (c) effect the combination, subdivision and/or reclassification of
outstanding Units as may be necessary or appropriate to give economic effect to equity investments in the Partnership by PubCo that are not accompanied by the issuance by the Partnership to PubCo of additional Units and to update the books and
records of the Partnership accordingly. 
  

	9.1.3	 References to Units Except as expressly provided in this Agreement to the contrary, any reference to
“Units” shall include the Common Units and Units of any other class or series that may be established in accordance with this Agreement. All Units of a particular class shall have identical rights in all respects as all other Units
of such class, except in each case as otherwise specified in this Agreement. 

  

	9.1.4	 Limitation on Issuances Notwithstanding anything to the contrary in this Agreement, the General Partner
shall not cause or permit the Partnership to issue, or authorize the issuance of, any Units unless PubCo has a sufficient number of Class A Common Shares authorized, available and reserved for issuance upon an exchange of such newly issued
Units for Class A Common Shares pursuant to an Exchange Transaction. 

  

	9.1.5	 Restriction on Number of “Partners” for Treasury Regulations Purposes In addition to the
restriction set out in Section 2.12, notwithstanding anything to the contrary in this Agreement, the Partnership shall not, and the General Partner shall not cause the Partnership to, issue any Units if such issuance would result in the
Partnership having more than seventy-five (75) “partners”, within the meaning of Treasury Regulations Section 1.7704-1(h) (but looking through all entities treated as transparent or
flow-throughs for U.S. federal income tax purposes) or if the Partnership already has more than seventy-five (75) “partners” but such issuance would further increase the number of “partners” in the Partnership; provided
that, for such purposes, the Partnership and the General Partner shall be entitled to assume that each person who is a Partner immediately before the Effective Time is treated as a single partner within the meaning of Treasury Regulations Section 1.7704-1(h) (but looking through all entities treated as transparent or flow-throughs for U.S. federal income tax purposes), unless otherwise required by applicable Law. 

 

	9.2	 Register The books and records of the Partnership shall be the definitive record of ownership of
each Unit and all relevant information with respect to each Partner. Unless the General Partner in its sole discretion shall determine otherwise, Units shall be uncertificated and recorded in the books and records of the Partnership.

  

	9.3	 Registered Partners The Partnership shall be entitled to recognize the exclusive right of a
Person registered on its records as the owner of Units for all purposes and shall not be bound to recognize any equitable or other claim to or interest in Units on the part of any other Person, whether or not it shall have express or other notice
thereof, except as otherwise provided by the Act or other applicable Law. 

  

	9.4	 Forfeiture of Common Units. Each PMEL Post-Combination Unitholder hereby agrees that any Common
Units (for the avoidance of doubt, including any Common Units which were formerly PMEL RCUs and were converted into Common Units pursuant to this Agreement) which, by virtue of the transactions contemplated by the Business Combination Agreement,
were received in substitution for PMEL Interests held by a PMEL Award Recipient, shall be subject to the same forfeiture provisions as contained in any corresponding PMEL Award Agreement. The General Partner shall have the authority pursuant to
Section 9.4 of this Agreement to cancel and extinguish for no consideration, automatically and without the consent of the applicable PMEL Post-Combination Unitholder (or PMEL Award Recipient), any Common

  
 36 

	 	
Units (and PubCo shall cancel and extinguish for no consideration the Acquiror Class B PMEL RSRs or the Class B Common Shares, as the case may be, held by such PMEL Post-Combination
Unitholder (or PMEL Award Recipient), on a one-for-one basis, without the consent of the applicable PMEL Post-Combination Unitholder (or PMEL Award Recipient)) to the
same extent the corresponding PMEL Interests would have been subject to forfeiture under the corresponding PMEL Award Agreement. 

  

	9.5	 Issuances, Repurchases and Redemptions, Recapitalizations 

 

	9.5.1	 Issuances by PubCo. 

(a) Subject to Section 9.5.1(b) and the Exchange Agreement, if, at any time after the Closing Date,
PubCo sells or issues Class A Common Shares or any other Equity Interests of PubCo (other than Class B Common Shares): 
  

	 	(i)	 the Partnership shall concurrently issue to PubCo an equal number of Common Units (if PubCo issues Class A
Common Shares), or an equal number of such other Equity Interests of the Partnership corresponding to the Equity Interests issued by PubCo (if PubCo issues Equity Interests other than Class A Common Shares), and with substantially the same
rights to dividends and Distributions (including Distributions upon liquidation) and other economic rights as those of such Equity Interests of PubCo so issued; and 

 

	 	(ii)	 PubCo shall concurrently contribute to the Partnership the net proceeds or other property received by PubCo, if
any, for such Class A Common Share or other Equity Interest. 

 (b) Notwithstanding anything to the
contrary contained in Section 9.5.1(a) or Section 9.5.1(c), this Section 9.5.1 shall not apply to: 
  

	 	(i)	 the issuance and distribution to holders of Class A Common Shares or other Equity Interests of PubCo of
rights to purchase Equity Interests of PubCo under a “poison pill” or similar shareholder rights plan (and upon exchange of Common Units for Class A Common Shares pursuant to the Exchange Agreement, such Class A Common Shares
will be issued together with a corresponding right under such plan); or 

  

	 	(ii)	 the issuance under PubCo’s employee benefit plans of any warrants, options, stock appreciation right,
restricted stock, restricted stock units, performance based award or other rights to acquire Equity Interests of PubCo, 

but Section 9.5.1 shall, in each of the foregoing cases, apply to the issuance of Equity Interests of PubCo in
connection with the exercise or settlement of such warrants, options, stock appreciation right, restricted stock units, performance based awards or other rights to acquire Equity Interests of PubCo. 

(c) Exercise or Conversion of PubCo Equity Interests In the event any outstanding Equity Interest of PubCo is
exercised or otherwise converted and, as a result, any Class A Common Shares or other Equity Interests of PubCo are issued (including as a result of the exercise of warrants of PubCo): 

  
 37 

	 	(i)	 the corresponding Equity Interests issued by the Partnership, if any, shall be similarly exercised or otherwise
converted, if applicable; 

  

	 	(ii)	 an equivalent number of Common Units or equivalent Equity Interests of the Partnership shall be issued to PubCo
as required by the first sentence of Section 9.5.1; and 

  

	 	(iii)	 PubCo shall concurrently contribute to the Partnership the net proceeds received by PubCo from any such
exercise or conversion. 

 (d) Issuance of Debt If at any time PubCo or any of its
Subsidiaries (other than the Partnership and its Subsidiaries) issues any securities in respect of or otherwise incurs indebtedness for borrowed money (“Debt”), PubCo or such Subsidiary shall Transfer to the Partnership the net
proceeds received by PubCo or such Subsidiary, as applicable, in exchange for such Debt in a manner that burdens the Partnership with the repayment of such Debt (including for example through a “back-to-back” loan from the PubCo or such Subsidiary to the Partnership). 
  

	9.5.2	 Issuance of New Common Units to PubCo Except pursuant to the Exchange Agreement, (a) the
Partnership may not issue any additional Common Units to PubCo or any of its Subsidiaries (other than Subsidiaries of the Partnership) unless substantially simultaneously therewith PubCo or such Subsidiary issues or Transfers an equal number of
newly-issued Class A Common Shares (or relevant Equity Interest of such Subsidiary) to another Person or Persons and contributes the net proceeds therefrom to the Partnership, and (b) the Partnership may not issue any other Equity
Interests of the Partnership to PubCo or any of its Subsidiaries (other than Subsidiaries of the Partnership) unless substantially simultaneously therewith PubCo or such Subsidiary issues or Transfers, to another Person, an equal number of
newly-issued shares of Equity Interests of PubCo or such Subsidiary with substantially the same rights to dividends and Distributions (including Distributions upon liquidation) and other economic rights as those of such Equity Interests of the
Partnership and contributes the net proceeds therefrom to the Partnership. 

  

	9.5.3	 Repurchases and Redemptions 

(a) Repurchases and Redemptions by PubCo Neither PubCo nor any of its Subsidiaries (other than the Partnership
and its Subsidiaries) may redeem, repurchase or otherwise acquire: 
  

	 	(i)	 Class A Common Shares pursuant to a PubCo Board approved repurchase plan or program (or otherwise in
connection with a transaction approved by the PubCo Board) unless substantially simultaneously therewith the Partnership redeems, repurchases or otherwise acquires from PubCo or such Subsidiary an equal number of Common Units for the same price per
security, if any, or 

  

	 	(ii)	 any other Equity Interests of PubCo or any of its Subsidiaries (other than the Partnership and its
Subsidiaries) pursuant to a PubCo Board approved repurchase plan or program (or otherwise in connection with a transaction approved by the PubCo Board) unless substantially simultaneously therewith the Partnership redeems, repurchases or otherwise
acquires from PubCo or such Subsidiary an equal number of the corresponding class or series of Equity Interests of the Partnership with the same rights to dividends and Distributions (including Distributions upon liquidation) and other economic
rights as those of such Equity Interests of PubCo or such Subsidiary for the same price per security, if any. 

  
 38 

 (b) Repurchases and Redemptions by the Partnership Subject to
Section 9.6, the Partnership may not redeem, repurchase or otherwise acquire: 
  

	 	(i)	 any Common Units from PubCo or any of its Subsidiaries (other than the Partnership and its Subsidiaries) unless
substantially simultaneously PubCo or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a PubCo Board approved repurchase plan or program (or otherwise in connection with a transaction approved by the PubCo Board) an equal
number of Class A Common Shares for the same price per security from holders thereof; or 

  

	 	(ii)	 any other Equity Interests of the Partnership from PubCo or any of its Subsidiaries (other than the Partnership
and its Subsidiaries) unless substantially simultaneously PubCo or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a PubCo Board approved repurchase plan or program (or otherwise in connection with a transaction approved by
the PubCo Board) for the same price per security an equal number of Equity Interests of PubCo (or such Subsidiary) of a corresponding class or series with substantially the same rights to dividends and Distributions (including Distributions upon
liquidation) and other economic rights as those of such Equity Interests of PubCo or such Subsidiary. 

(c) Cashless Redemptions Notwithstanding the foregoing Section 9.5.1 and Section 9.5.2, to the extent that any
consideration payable by PubCo in connection with the redemption, repurchase or acquisition of Class A Common Shares or other equity securities of PubCo or any of its Subsidiaries (other than the Partnership and its Subsidiaries) consists (in
whole or in part) of Class A Common Shares or such other Equity Interests (including in connection with the cashless exercise of an option or warrant (or other convertible right or security)), other than under PubCo’s employee benefit
plans for which there are no corresponding Common Units or other Equity Interests of the Partnership, the redemption, repurchase or acquisition of the corresponding Common Units or other Equity Interests of the Partnership shall be effectuated in a
substantially similar manner. 
  

	9.5.4	 Equity Subdivisions and Combinations 

(a) Limitation on the Partnership The Partnership shall not in any manner effect any subdivision (by any equity
split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of the outstanding Equity Interests of the Partnership unless accompanied by an
identical subdivision or combination, as applicable, of the outstanding related class or series of Equity Interest of PubCo, with corresponding changes made with respect to any other exchangeable or convertible Equity Interests of the Partnership
and PubCo. 
 (b) Limitation on PubCo PubCo shall not in any manner effect any subdivision (by any equity
split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of any class or series of Equity Interest of PubCo, unless accompanied by an
identical subdivision or combination, as applicable, of the outstanding related class or series of Equity Interests of the Partnership, with corresponding changes made with respect to any applicable exchangeable or convertible Equity Interests of
the Partnership and PubCo. 

  
 39 

 (c) Maintenance of one-to-one ratio of Common Units to PubCo’s Class A Common Shares For the avoidance of doubt, but subject to Section 9.1, Section 9.2, Section 9.5 and
Section 9.6, the Partnership and the General Partner shall be permitted to undertake all actions, including an issuance, redemption, reclassification, distribution, division or recapitalization, with respect to the Common Units or the
Restricted Common Units as the General Partner determines is necessary to maintain at all times a one-to-one ratio between (i) the number of Common Units
owned by PubCo, directly or indirectly, and the number of outstanding Class A Common Shares; and (ii) the number of outstanding Class B Common Shares held, directly or indirectly, by any Partner and the number of Common Units (other
than Restricted Common Units) held (directly or indirectly) by such Partner, disregarding for purposes of maintaining the one-to-one ratios in clause (i): 

 

	 	(i)	 options, rights or securities of PubCo issued under any plan involving the issuance of any Equity Interests
that are convertible into or exercisable or exchangeable for Class A Common Shares, 

  

	 	(ii)	 treasury stock, or 

  

	 	(iii)	 preferred stock or other debt or equity securities (including warrants, options or rights) issued by PubCo that
are convertible into or exercisable or exchangeable for Class A Common Shares (but in each case prior to such conversion, exercise or exchange). 

  

	9.5.5	 Redemptions pursuant to the Exchange Agreement If the Partnership is obliged, pursuant to
Section 2.2 of the Exchange Agreement, to cancel a number of Common Units surrendered to it by a Limited Partner (a “Surrendering Partner”), those surrendered Common Units shall be treated as redeemed by the Partnership and
shall be cancelled immediately upon redemption. The recorded balance of the Equity Contribution and (if any) the Advance of such Limited Partner shall each be reduced, on that surrender and redemption, by a proportionate amount (equal to the
proportion which the number of surrendered Common Units bears to the total number of Common Units held by that Limited Partner immediately prior to that surrender (such proportion the “Exchanged Proportion”)), and the recorded
balance of the Equity Contribution and Advance of PubCo shall each be correspondingly and automatically increased by the same respective amounts. The Partnership shall issue a number of Common Units to PubCo, as required by Section 2.2 of the
Exchange Agreement, equal to the number of Common Units surrendered by the Surrendering Partner and redeemed by the Partnership and on the issuance of such Common Units a proportion of the Surrendering Partner’s right to the repayment of its
Advance equal to the Exchanged Proportion shall hereby be assigned to PubCo. 

  

	9.6	 Restricted Common Units. 

 

	9.6.1	 Restricted Common Units and Vesting Each Restricted Common Unit will be held in accordance with this
Agreement unless and until a Vesting Event occurs with respect to such Restricted Common Unit. Upon the occurrence of a Vesting Event, on the Conversion Date, each applicable Restricted Common Unit with respect to which a Vesting Event has occurred
shall be converted immediately and automatically, without any further action on the part of the holder thereof or any other person (including the Partnership, the General Partner and PubCo) into a Common Unit, with all rights and privileges of a
Common Unit under this Agreement from and 

  
 40 

	 	
after the Conversion Date, subject in all respects to Section 9.4. Notwithstanding anything to the contrary contained in this Agreement or the Exchange Agreement, no Partner shall be
permitted to effect an Exchange Transaction with respect to any Restricted Common Units, and in no event shall the Partnership or PubCo effect an Exchange Transaction with respect to any Restricted Common Unit unless and until a Vesting Event and
Conversion Date has occurred with respect to such Restricted Common Unit and it has been converted to a Common Unit in accordance with the terms hereof. For the avoidance of doubt and without limiting the immediately foregoing sentence, in the event
that a Vesting Event, Conversion Date and conversion into Common Unit has occurred in respect of a Restricted Common Unit, the Partnership and PubCo may effect an Exchange of such then converted Common Unit in accordance with this Agreement and the
Exchange Agreement. 

  

	9.6.2	 HSR Act & Conversion Notwithstanding anything to the contrary contained in this
Agreement, if, upon the occurrence of a Vesting Event, a filing is required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 of the United States of America, and the rules and regulations promulgated thereunder (“HSR
Act”), for the immediate conversion of any Restricted Common Unit into a Common Unit, then the Conversion Date with respect to each such Restricted Common Unit shall be delayed until the earlier of (i) such time as the required filing
under the HSR Act has been made and the waiting period applicable to such conversion under the HSR Act shall have expired or been terminated or (ii) such filing is no longer required, at which time such conversion shall automatically occur
without any further action by the holder of any such Restricted Common Unit. Each of the Partners and PubCo agree to promptly take all actions required to make such filing under the HSR Act and the filing fee for such filing shall be paid by the
Partnership. 

  

	9.6.3	 Issuance on Conversion On the applicable Conversion Date for each Restricted Common Unit that is not a
PMEL RCU, PubCo shall issue to each Continuing Partner that holds a Acquiror Class B Earnout RSR (as defined in the Business Combination Agreement) that vests on such Conversion Date, one Class B Common Share. On the applicable Conversion
Date for each Restricted Common Unit that is a PMEL RCU, PubCo shall issue to each PMEL Post-Combination Unitholder that holds an Acquiror Class B PMEL RSR that vests on such Conversion Date, one Class B Common Share. PubCo hereby agrees
to reserve for issuance at all times an adequate number of Class B Common Shares to permit the issuance of all Class B Common Shares assuming (x) all of the Acquiror Class B Earnout RSRs were to vest under the terms of the
Business Combination Agreement and (y) all of the PMEL Post-Combination Unitholders’ Acquiror Class B PMEL RSRs were to vest under their applicable terms. 

 

	9.6.4	 Cancellation of Restricted Common Units  

 

	9.6.5	 To the extent that, in the case of the Restricted Common Units that are not PMEL RCUs, by the Earnout
Expiration Date (as defined in the Business Combination Agreement), a Vesting Event has not occurred with respect to a Restricted Common Unit, and such Restricted Common Unit has not vested and converted into a Common Unit, then as of the Earnout
Expiration Date, immediately and without any further action under this Agreement, on such date, any such Restricted Common Units outstanding under this Agreement shall be cancelled and extinguished for no consideration. To the extent that a PMEL RCU
is forfeited pursuant to the terms of the applicable PMEL Agreement (with the terms of such agreement as applied to the PMEL RCUs in accordance with the final sentence of Section 9.4), immediately and without any further action under this
Agreement, on the date of forfeiture, such PMEL RCU shall be cancelled and extinguished for no consideration. Upon the cancellation and extinguishment of any Restricted Common Unit pursuant to this Section 9.6.5, PubCo shall cancel and
extinguish for no consideration the corresponding Acquiror Class B Earnout RSR or Acquiror Class B PMEL RSR on a one-for-one basis, without the consent of the
applicable holder thereof. 

  
 41 

	9.6.6	 U.S. Tax Treatment The parties hereto intend that, for U.S. federal income tax purposes, (i) the
Restricted Common Units received by the Continuing Partners in connection with the Business Combination Agreement not be treated as being received in connection with the performance of services and (ii) no such Partner be treated as having
taxable income or gain as a result of such receipt of such Restricted Common Units or as a result of holding any such Restricted Common Units at the time of any Vesting Event (other than as a result of corrective allocations made pursuant to
Section 7.4.10) and the Partnership shall prepare and file all tax returns consistent therewith unless otherwise required by a “determination” within the meaning of Section 1313(a) of the Code.

 SECTION 10 

TRANSFER RESTRICTIONS 
  

	10.1	 Transfers of Units 

 

	10.1.1	 Restriction on Transfers Except as otherwise agreed to in writing between the General Partner and the
applicable Partner and reflected in the books and records of the Partnership or as otherwise provided in this Section 10, but without limiting the Lock-Up Agreement, no Partner may Transfer all or any
portion of its Units or other interest in the Partnership (or beneficial interest therein) without the prior consent of the General Partner, which consent may be given or withheld, or made subject to such conditions (including the receipt of such
legal opinions and other documents that the General Partner may require) as are determined by the General Partner, in each case in the General Partner’s sole discretion, and which consent may be in the form of a plan or program entered into or
approved by the General Partner, in its sole discretion. Any such determination in the General Partner’s sole discretion in respect of Units shall be final and binding. Such determinations need not be uniform and may be made selectively among
Partners, whether or not such Partners are similarly situated, and shall not constitute the breach of any duty hereunder or otherwise existing at law, in equity or otherwise. Any purported Transfer of Units that is not in accordance with, or
subsequently violates, this Agreement shall be, to the fullest extent permitted by law, null and void. If a Partner Transfers all or a portion of its Common Units to a Transferee in compliance with this Agreement, the Partner shall transfer to such
Transferee an equal number of Class B Common Shares. 

  

	10.1.2	 Lock-Up Period Each Partner hereby agrees and covenants that
such Partner will not, during the Lock-Up Period, Transfer any Units in the Partnership or any equity interests of PubCo (including any Class A Common Shares or Class B Common Shares) received or
retained as consideration under the Business Combination Agreement, including any securities held in escrow or otherwise issued or delivered after the Closing pursuant to the Business Combination Agreement (collectively, the “Restricted
Securities”) (a “Prohibited Transfer”) except to the extent provided in Section 10.1.5 or any applicable restrictions on Transfer are waived in accordance with the
Lock-Up Agreement. If any Prohibited Transfer is made or attempted contrary to the provisions of this Agreement, such purported Prohibited Transfer shall be null and void ab initio, and the Partnership
and PubCo shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders for any purpose. In order to enforce this Section 10.1.2, the Partnership and PubCo may impose
stop-transfer instructions with respect to the Restricted Securities of each Partner until the end of the Lock-Up Period, as well as include customary legends on any certificates for any of the Restricted
Securities reflecting the restrictions under this Section 10.1. 

  
 42 

	10.1.3	 End of Lock-Up Period Notwithstanding anything otherwise to the
contrary in this Agreement, following the expiration of the Lock-Up Period, each Partner that is a Partner holding at least 3% of the Common Percentage
Interest (excluding, for purposes of this calculation, Common Units then owned by PubCo or any Subsidiary of PubCo (if any)) may Transfer all or any portion of its Common Units in a Transfer that complies with Section 10.5, without the consent
of the General Partner or any other Person. 

  

	10.1.4	 Exchange Transactions Notwithstanding anything otherwise to the contrary in this Agreement, following
the expiration of the Lock-Up Period, each Partner may Transfer Units in Exchange Transactions pursuant to, and in accordance with, the Exchange Agreement; provided that, in the case of any Partner
other than a Partner holding at least 3% of the Common Percentage Interest (excluding, for purposes of this calculation, Common Units then owned by the PubCo (if any) or any Subsidiary of the PubCo (if any)), such Exchange Transactions shall
be effected in compliance with reasonable policies that the General Partner may adopt or promulgate from time to time and advise the Partners of in writing (including policies requiring the use of designated administrators or brokers) in its
reasonable discretion; provided, further, that if such policies conflict with the terms of the Exchange Agreement, the provisions of the Exchange Agreement shall apply in lieu thereof to any Exchange Transaction to the extent of such
conflict. 

  

	10.1.5	 Family Group and Affiliate Transfers Notwithstanding anything otherwise to the contrary in this
Section 10.1, but subject to the limitations set forth herein and compliance with, and to the extent otherwise permitted by, the Lock-Up Agreement, an individual Partner may Transfer all or any portion of
his, her or its Restricted Securities without consideration to (i) any member of his or her Family Group or (ii) any Affiliate of such Partner (including any direct or indirect partner, shareholder, equityholder of such Partner or any
Affiliated investment fund or vehicle of such Partner or such Partner’s direct or indirect partners, shareholders or equityholders), but excluding any Affiliate under this clause (ii) who operates or engages in a business which
competes with the business of PubCo or the Partnership and (iii) to a trust solely for the benefit of such Partner and such Partner’s Family Group (or a re-Transfer of such Restricted Securities by
such trust back to such Partner upon the revocation of any such trust) or pursuant to the applicable Laws of descent or distribution among such Partner’s Family Group, in each case, in a Transfer that complies with
Section 10.5 (each of clauses (i)-(iii), an “Exempt Transfer”); provided that, (x) the restrictions contained in this Section 10 shall apply to an Exempt Transfer and (y) the
restrictions contained in this Agreement will continue to apply to the Restricted Securities after any Exempt Transfer and each Transferee of Restricted Securities shall agree in writing, by entering into an appropriate supplemental agreement in
such form and terms as the General Partner may reasonably specify, prior to and as a condition precedent to the effectiveness of such Exempt Transfer, to be bound by the provisions of this Agreement, without modification or condition, subject only
to the consummation of such Exempt Transfer. Upon the Exempt Transfer of Restricted Securities, the transferor will deliver written notice to the Partnership, which notice will disclose in reasonable detail the identity of such Transferee(s) and
shall include an executed original counterpart of this Agreement in a form acceptable to the General Partner. Notwithstanding the foregoing and any other term in this Agreement, (a) notice of such an Exempt Transfer shall be forthwith
advertised in Iris Oifigiúil as so required by the Act, and until notice of such transfer is so advertised, the arrangement or transaction shall, for the purposes of the Act, be deemed to be of no effect, and (b) no
party hereto shall avoid the provisions of this Agreement by making one or more Exempt Transfers to one or more Transferees and then disposing of all or any portion of such party’s interest in such Transferee if such disposition would result in
such Transferee ceasing to be a Permitted Transferee. Without limiting the Lock-Up Agreement, the General Partner may implement other policies and procedures to permit the Transfer of Restricted Securities by
the Partners for personal planning purposes and any such Transfer effected in compliance with such policies and procedures shall not require the prior consent of the General Partner. 

  
 43 

	10.1.6	 Purported Transfers Void Any Transfer or attempted Transfer of any Units in violation of any provision
of this Agreement shall, to the fullest extent permitted by law, be null and void ab initio, and the Partnership will not record such Transfer on its books or treat any purported Transferee of such Units as the owner of such securities for
any purpose. 

  

	10.2	 Mandatory Exchanges The Partnership may, with the approval of the board of the General Partner,
at any time and from time to time, without the consent of any Partner or other Person, cause to be Transferred to PubCo in an Exchange Transaction any and all Units, except for Units held by any Partner holding at least 3% of the Common Percentage
Interest (excluding, for purposes of this calculation, Common Units then owned by PubCo or any Subsidiary of PubCo) (a “Mandatory Exchange”); provided that, if at any time after the expiration of the Lock-Up Period: 

 (a) (x) the General Partner is not a wholly-owned
Subsidiary of PubCo or (y) for any other reason the Partnership’s nationally recognized tax advisors are unable to render an opinion to the Partnership at least at a “more likely than not” level of comfort that a wholly-owned
Subsidiary of PubCo constitutes a “general partner” within the meaning of Treasury Regulations Section 1.7704-1(k)(1), 

(b) the Partnership has more than seventy-five (75) “partners”, within the meaning of Treasury Regulations Section 1.7704-1(h) (but looking through all entities treated as transparent or flow-throughs for U.S. federal income tax purposes), and 

(c) there are not binding agreements by and among Partners and the Partnership and/or its assignees to sell Units in a manner
that will not cause the Partnership to be classified as a “publicly traded partnership” within the meaning of Section 7704 of the Code pursuant to one or more closings that will occur no later than seventy-five (75) days of
expiration of the Lock-Up Period and that would cause the Partnership to have seventy-five (75) or fewer “partners”, within the meaning of Treasury Regulations
Section 1.7704-1(h) (but looking through all entities treated as transparent or flow-throughs for U.S. federal income tax purposes), upon the consummation of the transactions contemplated by such
agreements (including, agreements to tender Units to the Partnership or one or more purchasers approved by the Partnership), 
 then the
Partnership shall promptly, and in any event within seventy-five (75) days of the expiration of the Lock-Up Period, cause a Mandatory Exchange to be effected with respect to a number of Partners holding
less than 3% of the Common Percentage Interest (excluding, for purposes of this calculation, Common Units then owned by PubCo or any Subsidiary of PubCo) sufficient to cause the Partnership to have no more than seventy-five (75)
“partners”, within the meaning of Treasury Regulations Section 1.7704-1(h) (but looking through all entities treated as transparent or flow-throughs for U.S. federal income tax purposes), upon
the consummation of such Mandatory Exchange. Any Mandatory Exchange need not be uniform and may be made by the Partnership and PubCo selectively among Partners, whether or not such Partners are similarly situated; provided that, in the event that a
tender offer, share exchange offer, take-over bid, recapitalization or similar transaction with respect to any Class A Common Shares (a “PubCo Offer”) is proposed by PubCo or is proposed to PubCo or its stockholders and
approved 

  
 44 

 
by the PubCo Board or is otherwise effected or to be effected with the consent or approval of the PubCo Board that would result in PubCo undergoing a Change of Control, then the General Partner
shall require, and each Partner shall be deemed to effect, an Exchange Transaction with respect to any and all Units held by all Partners conditioned upon, and subject to, the consummation of such PubCo Offer or Change of Control, in each case, to
the extent that such Partner has not effected an Exchange Transaction with respect to all of its Units prior to the consummation of such transaction. 
  

	10.3	 Approved Qualified Transaction 

 

	10.3.1	 Drag-Along Right In the event that the General Partner and the holders of a majority of the voting power
of all outstanding capital stock of PubCo entitled to vote thereon approve a Qualified Transaction (the “Approved Qualified Transaction”), each other Partner (each, a “Required Partner”) agrees to Transfer all of
such Required Partner’s Units in connection with such Approved Qualified Transaction (the “Drag-Along Right”) for an amount of consideration per Unit and corresponding Class B Common Share equal (before taking into account
any rights such Required Partner may have under the Tax Receivable Agreement) to the amount of consideration to be received per Class A Common Share by the holders thereof (the “Drag Price”), and otherwise with respect to such
Units on the same terms and conditions as apply to the Class A Common Shares in such Approved Qualified Transaction, with such modifications as are appropriate, as determined in good faith by the General Partner, solely to reflect the fact that
Units and corresponding Class B Common Shares rather than Class A Common Shares will be Transferred in the first instance by such Partner. Any Transfer effected in connection with the Drag-Along Right shall be structured in the sole
discretion of the General Partner and, without limitation to any other structure, the General Partner will use its reasonable best efforts expeditiously and in good faith to take all such actions and do all such things as are necessary or desirable
to enable and permit the Partners to participate in such Approved Qualified Transaction to the same extent or on an economically equivalent basis as the holders of Class A Common Shares without discrimination; provided that, without
limiting the generality of this sentence, the General Partner will use its reasonable best efforts expeditiously and in good faith to ensure that such Partners may participate in each such Approved Qualified Transaction without being required to
have their Common Units and Class B Common Shares redeemed (or, if so required, to ensure that any such redemption shall be effective only upon, and shall be conditional upon, the closing of such Approved Qualified Transaction, or, as
applicable, to the extent necessary to exchange the number of Common Units being repurchased). 

  

	10.3.2	 Drag-Along Notice PubCo shall send written notice (the “Drag-Along Notice”) to the
Partnership and the Required Partners at least thirty (30) days prior to the closing of the Approved Qualified Transaction notifying them that such Required Partners will be required to sell all (but not less than all) of their Units in such
sale, and setting forth (i) a copy of the written proposal or agreement pursuant to which the Approved Qualified Transaction will be effected, (ii) the Drag Price, (iii) the terms and conditions of Transfer and payment and
(iv) the date and location of and procedures for selling the Units. In the event that the information set forth in the Drag-Along Notice changes from that set forth in the initial Drag-Along Notice, a subsequent Drag-Along Notice shall be
delivered by PubCo no less than seven (7) days prior to the closing of the Approved Qualified Transaction. Notwithstanding the foregoing, to the extent that any of the foregoing information to be included in the Drag-Along Notice is publicly
available, PubCo shall not be required to include such information in the Drag-Along Notice or deliver a subsequent Drag-Along Notice. Each Required Partner shall thereafter be obligated to sell their Units and corresponding Class B Common
Shares on the terms set forth in the Drag-Along Notice.

	10.3.3	 Obligation of Required Partners to Sell Upon receipt of a Drag-Along Notice, each Required Partner
receiving such notice shall be obligated to sell all of its Units and corresponding Class B Common Shares in the Approved Qualified Transaction as contemplated by the Drag-Along Notice for the Drag Price, on the terms and conditions described
in this Section 10.3, including by executing any document containing customary representations, warranties and agreements with respect to itself and its ownership of the Units or Class B Common Shares, as applicable,
as requested by the General Partner in connection with the Approved Qualified Transaction, which representations, warranties, indemnities and agreements shall be substantially the same as those contained in any letter of transmittal to be executed
by the holders of Class A Common Shares with such modifications as are appropriate, as determined in good faith by the General Partner, solely to reflect the fact that Units or Class B Common Shares, as applicable, rather than Class A
Common Shares will be transferred by such Required Partner. The General Partner and each Required Partner shall cooperate in good faith in connection with the consummation of the Approved Qualified Transaction. 

 

	10.4	 Encumbrances 

No Partner or Assignee may create an Encumbrance with respect to all or any portion of its Units (or any beneficial interest therein) other
than Encumbrances that run in favor of the Partner unless the General Partner consents in writing thereto, which consent may be given or withheld, or made subject to such conditions as are determined by the General Partner, in the General
Partner’s sole discretion (but without limiting the Lock-Up Agreement). Consent of the General Partner shall be withheld until the holder of the Encumbrance acknowledges the terms and conditions of this
Agreement. Any purported Encumbrance that is not in accordance with this Agreement shall be, to the fullest extent permitted by law, null and void. 
  

	10.5	 Further Restrictions. 

 

	10.5.1	 Terms for New Issuances Units issued from time to time after the date of this Agreement, including Units
issued under equity incentive plans of the Partnership or PubCo (or upon settlement of awards granted under such plans), may be subject to such additional or other terms and conditions, including with regard to vesting, forfeiture, minimum retained
ownership and Transfer, as may be agreed between the General Partner and the applicable Partner and reflected in the books and records of the Partnership. Such requirements, provisions and restrictions need not be uniform and may be waived or
released by the General Partner in its sole discretion with respect to all or a portion of the Units owned by any one or more Partners at any time and from time to time, and shall not constitute the breach of any duty hereunder or otherwise existing
at law, in equity or otherwise. 

  

	10.5.2	 Prohibitions on Transfer Notwithstanding any contrary provision in this Agreement, in no event may any
Transfer of a Unit (other than, in each case, in accordance with the Exchange Agreement) be made by any Partner or Assignee if the General Partner determines that: 

(a) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit; 

(b) except pursuant to an Exchange Transaction, such Transfer would require the registration of such transferred Unit or of any
Class of Unit pursuant to any applicable U.S. federal or state securities Laws (including, without limitation, the Securities Act or the Exchange Act) or other non-U.S. securities Laws or would constitute
a non-exempt distribution pursuant to applicable provincial or state securities Laws; 

  
 46 

 (c) such Transfer would cause (i) all or any portion of the assets of
the Partnership to (A) constitute “plan assets” (under ERISA, the Code or any applicable Similar Law) of any existing or contemplated Partner, or (B) be subject to the provisions of ERISA, Section 4975 of the Code or any
applicable Similar Law, or (ii) the General Partner or PubCo to become a fiduciary with respect to any existing or contemplated Partner, pursuant to ERISA, any applicable Similar Law, or otherwise; 

(d) would result in a breach of Section 2.12; 

(e) to the extent requested by the General Partner, the Partnership does not receive such legal and/or tax opinions and written
instruments (including copies of any instruments of Transfer and such Assignee’s consent to be bound by this Agreement as an Assignee) that are in a form satisfactory to the General Partner, as determined in the General Partner’s sole
discretion; provided that, no such legal and/or tax opinions shall be required for a Transfer by a Partner holding at least 3% of the Common Percentage Interest (excluding, for purposes of
this calculation, Common Units then owned by PubCo (if any) or any Subsidiary of PubCo (if any)); 
 (f) such Transfer would
cause the Partnership to be treated as having more than seventy-five (75) “partners” within the meaning of Treasury Regulations Section 1.7704-1(h) but looking through all entities treated as
transparent or flow-through for U.S. federal income tax purposes or if the Partnership already has more than seventy-five (75) “partners” but such issuance would further increase the number of “partners” in the Partnership; 

(g) the General Partner shall reasonably determine that such Transfer would pose a material risk that the Partnership would be
treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the Treasury Regulations promulgated thereunder. 

All determinations with respect to this Section 10.5 shall be made by the General Partner in its sole discretion; provided,
however, that all such determinations with respect to a Partner holding at least 3% of the Common Percentage Interest (excluding, for purposes of this calculation, Common Units then owned by PubCo (if any) or any Subsidiary of PubCo (if any))
shall be made by the General Partner exercising its reasonable discretion. 
  

	10.5.3	 Treasury Regulation, Code and Partner Restrictions In addition, notwithstanding any contrary provision
in this Agreement, to the extent the General Partner shall reasonably determine that interests in the Partnership do not meet the requirements of Treasury Regulations Section 1.7704-1(h) (determined
taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3) in a taxable year, provided that, for such purpose, the Partnership and the General Partner shall assume that each
Continuing Partner is treated as a single “partner” within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)) unless otherwise required by applicable Law), in no event may any Transfer or assignment of Units by any Partner be made if such Transfer would (i) be considered to be effected on
or through an “established securities market” or a “secondary market or the substantial equivalent thereof” as such terms are used in Treasury Regulations Section 1.7704-1, (ii)
materially increase the possibility of the Partnership becoming a “publicly traded partnership” within the meaning of Section 7704 of the Code, or (iii) cause the Partnership to be treated as a “publicly traded
partnership” within the meaning of Section 7704 of the Code or successor provision of the Code or to be treated as an association taxable as a corporation pursuant to the Code. For the avoidance of doubt, any Transfer that constitutes a

  
 47 

	 	
“block transfer” within the meaning of Treasury Regulation Section 1.7704-1(e)(2) shall not be considered to be (i) effected on or
through an “established securities market” or a “secondary market or the substantial equivalent thereof” as such terms are used in Treasury Regulations Section 1.7704-1, (ii)
materially increase the possibility of the Partnership becoming a “publicly traded partnership” within the meaning of Section 7704 of the Code, or (iii) cause the Partnership to be treated as a “publicly traded
partnership.” Notwithstanding anything contrary in this Agreement, in no event may any Transfer, assignment of Units, or other transfer of beneficial entitlement to Units by any Partner be made if such Transfer would cause the Partnership to be
treated as having more than seventy-five (75) “partners” within the meaning of Treasury Regulations Section 1.7704-1(h) but looking through all entities treated as transparent or flow-through
for U.S. federal income tax purposes or if the Partnership already has more than seventy-five (75) “partners” but such issuance would further increase the number of “partners” in the Partnership. 

 

	10.5.4	 Timing of Permitted Transfers Transfers of Units (other than pursuant to an Exchange Transaction) that
are otherwise permitted by this Section 10 may only be made effective as of the first day of a fiscal quarter of the Partnership, unless the General Partner otherwise agrees. 

 

	10.5.5	 Void Transfers To the fullest extent permitted by law, any Transfer in violation of this Section 10
(including the final sentence of Section 10.5.3) shall be deemed null and void ab initio and of no effect. 

  

	10.5.6	 Notice of the Transfer Notwithstanding any other term in this Agreement, notice of any Transfer shall be
forthwith set out in Iris Oifigiúil as so required by the Act, and until notice of such Transfer is so made, the arrangement or transaction shall, for the purposes of the Act, be deemed to be of no effect.

  

	10.5.7	 Lock-Up Agreement Notwithstanding any other term in this
Agreement, nothing in this Agreement shall limit a Partner’s obligations pursuant to the Lock-Up Agreement. 

  

	10.6	 Admissions, Resignations and Removals  

 

	10.6.1	 No Partner will be removed or entitled to resign from being a Partner of the Partnership except in accordance
with this Section 10.6 and Section 10.7 hereof. No Person may be admitted to the Partnership as an additional general partner or substitute general partner without the prior written consent of each incumbent General Partner, which consent
may be given or withheld, or made subject to such conditions as are determined by each incumbent general partner, in each case in the sole discretion of each incumbent general partner. Any additional General Partner or substitute partners of the
General Partner shall be admitted as a general partner of the Partnership by executing and delivering to the existing General Partner an appropriate supplement to this Agreement pursuant to which the Person agrees to be bound by the terms and
conditions of this Agreement, as it may be amended from time to time, and thereafter shall be authorized to, and shall, continue the Partnership without dissolution. Except as otherwise provided in Section 10 or the Act, no admission,
substitution, resignation or removal of a Partner will cause the dissolution of the Partnership. To the fullest extent permitted by law, any purported admission, resignation or removal that is not in accordance with this Agreement shall be null and
void. 

  

	10.6.2	 It is agreed that ProKidney GP Ireland Limited shall resign as general partner of the Partnership as and from
the admission of ProKidney Corp. GP Limited to the Partnership, which admission shall take effect upon the Closing on the Effective Date. ProKidney GP Ireland Limited, as its final act as general partner of the Partnership immediately prior to the
Closing, hereby approves the Post-Recapitalization Unit Issuance, if any such Post-Recapitalization Unit Issuance occurs pursuant to the Business Combination Agreement. 

  
 48 

	10.7	 Admission of Assignees as Substitute Limited Partners  

 

	10.7.1	 Conditions for Admission as Limited Partner A proposed assignee will become a substitute Limited Partner
only if and when each of the following conditions is satisfied: 

 (a) the General Partner consents in
writing to such admission, which consent may be given or withheld, or made subject to such conditions as are determined by the General Partner, in each case in the General Partner’s sole discretion; 

(b) if required by the General Partner, the General Partner receives written instruments (including copies of any instruments
of Transfer, a notarised and apostilled copy (in English) of such assignee’s governing documents (if the Assignee is not a natural person) and such Assignee’s consent to be bound by this Agreement as a substitute Partner) that are in a
form satisfactory to the General Partner (as determined in its sole discretion); 
 (c) if required by the General Partner,
the General Partner receives an opinion of counsel satisfactory to the General Partner to the effect that such Transfer is in compliance with this Agreement and all applicable Law; 

(d) if required by the General Partner, the parties to the Transfer, or any one of them, pays all of the Partnership’s
reasonable expenses connected with such Transfer (including the reasonable legal and accounting fees of the Partnership); 

(e) notice of the Transfer is set out in Iris Oifigiúil as so required by the Act; and 

(f) other than where the assignee is a Permitted Transferee of PubCo and such Transfer occurs after the expiration of the Lock-Up Period, the assignee enters into a written agreement with the Partnership and PubCo agreeing to be bound by the transfer restrictions in section 2 of the Lock-Up
Agreement. 
  

	10.8	 Resignation and Removal of Partners Subject to Section 10.6, if a Partner ceases to hold any
Units, then such Partner shall cease to be a Partner and to have the power to exercise any rights or powers of a Partner of the Partnership, and shall be deemed to have resigned from the Partnership. 

 

	10.9	 Withholding In the event any Transfer is permitted pursuant to this Section 10, the
transferring parties shall demonstrate to the satisfaction of the General Partner either that no withholding is required in connection with such transfer under applicable U.S. federal, state or local or
non-U.S. law (including under Sections 1445 or 1446 of the Code) or that any amounts required to be withheld in connection with such transfer under applicable U.S. federal, state or local or non-U.S. law (including under Section 1446 of the Code, other than by reason of Section 1446(f)(4)) have been so withheld. 

  
 49 

	10.10	 Allocations in Respect of Transferred Units. With regard to PubCo’s acquisition of the New Company
Common Units (as defined in the Business Combination Agreement), Profits or Losses shall be allocated to the Partners of the Partnership so as to take into account the varying interests of the Partners in the Partnership using an “interim
closing of the books” method in a manner that complies with the provisions of Section 706 of the Code and the Treasury Regulations promulgated thereunder. If during any taxable year there is any other change in any Partner’s Units in
the Partnership, the General Partner shall consult in good faith with the Continuing Partner Representative and the tax advisors to the Partnership and allocate the Profits or Losses to the Partners of the Partnership so as to take into account the
varying interests of the Partners in the Partnership using an “interim closing of the books” method in a manner that complies with the provisions of Section 706 of the Code and the Treasury Regulations promulgated thereunder;
provided, however, that such allocations may instead be made in another manner that complies with the provisions of Section 706 of the Code and the Treasury Regulations promulgated thereunder and that is selected by the General Partner (with
the prior written consent of the Requisite Continuing Partners, not to be unreasonably withheld, conditioned or delayed); provided that, the Requisite Continuing Partners shall not have the consent right described in this Section 10.10 in the
event that the Continuing Partners collectively own less than 10% of the Units. 

 SECTION 11 

DISSOLUTION AND WINDING UP OF THE PARTNERSHIP 
  

	11.1	 No dissolution The Partnership shall not be dissolved by the admission of additional Partners or
resignation of Partners in accordance with the terms of this Agreement. The Partnership may be dissolved, liquidated, wound up and terminated only pursuant to the provisions of this Section 11. 

 

	11.2	 Dissolution The Partnership will be dissolved and its affairs wound up on the happening of any of the
following events: 

 (a) any event which makes it unlawful for the business of the Partnership to be
carried on by the Partners; 
 (b) the written consent of all Partners; or 

(c) the General Partner resolves to dissolve the Partnership in its reasonable discretion and with the consent of PubCo;
provided that, in the event of a dissolution pursuant to this clause (c), the relative economic rights of each Class of Units immediately prior to such dissolution shall be preserved to the greatest extent practicable with respect to
Distributions made to Partners pursuant to Section 11.4 below in connection with the winding up of the Partnership, taking into consideration tax and other legal constraints that may adversely affect one or more parties hereto and subject to
compliance with applicable Laws and regulations, unless, and to the extent that, with respect to any Class of Units, holders of not less than 90% of the Units of such Class consent in writing to a treatment other than as described above.

  

	11.3	 Effectiveness of Dissolution Dissolution of the Partnership shall be effective on the day on which the
event described in Section 11.2 occurs, but the Partnership shall not terminate until the winding up of the Partnership has been completed, and the assets of the Partnership have been distributed as provided in Sections
11.4.3 and 11.5. 

  

	11.4	 Liquidation If the Partnership is dissolved pursuant to Section 11.2, the
Partnership shall be liquidated and its business and affairs wound up in accordance with the Act and the following provisions: 

  

	 	11.4.1	 Liquidator. The General Partner, or, if the General Partner is unable to do so, a Person selected by the
General Partner, shall act as liquidator to wind up the Partnership (the “Liquidator”). The Liquidator shall have full power and authority to sell, assign, and encumber any or all of the Partnership’s assets and to wind up
and liquidate the affairs of the Partnership in an orderly and business-like manner. 

  
 50 

	 	11.4.2	 Accounting. As promptly as possible after dissolution and again after final liquidation, the Liquidator
shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Partnership’s assets, liabilities and operations through the last day of the calendar month in which the dissolution occurs or the final
liquidation is completed, as applicable. 

  

	 	11.4.3	 Distribution of Proceeds. The Liquidator shall liquidate the assets of the Partnership and Distribute
the proceeds of such liquidation in the following order of priority: 

 (a) first, to the payment of all
of the Partnership’s debts and liabilities to its creditors (save for amounts owed to Partners, including Advances) and the expenses of liquidation; 

(b) second, to the payment to the Partners of any debts (and any accrued interest thereon), other than Advances, owed by the
Partnership to such Partners; and 
 (c) third, to the payment to the Partners pro rata based on the number of
Participating Units then held by each Partner, and such payments to each Partner shall be applied with respect to such Partner first in reducing the balance of any Advances (if any) owing to that Partner, next in repaying the capital contributed by
that Partner, and thereafter as a distribution of surplus to that Partner. 
  

	11.5	 Time for Liquidation A reasonable amount of time shall be allowed for the orderly
liquidation of the assets of the Partnership and the discharge of liabilities to creditors so as to enable the Liquidator to minimize the losses attendant upon such liquidation. Notwithstanding the provisions of Section 11.4, but subject to the
order of priorities set forth therein, if upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss (or would otherwise not be
beneficial) to the Partners, the Liquidator may, in its sole discretion, defer for a reasonable time the winding up of any assets except those necessary to satisfy Partnership liabilities (other than loans to the Partnership by Partners) and
reserves. Subject to the order of priorities set forth in Section 11.4.3, the Liquidation Agent may, in its sole discretion, distribute to the Partners, in lieu of cash, either (i) all or any portion of such remaining Partnership assets in-kind in accordance with the provisions of Section 11.4.3, (ii) as tenants in common and in accordance with the provisions of Section 11.4.3, undivided interests in all or any portion of such Partnership
assets or (iii) a combination of the foregoing. Any such Distributions in kind shall be subject to (x) such conditions relating to the disposition and management of such assets as the Liquidator deems reasonable and equitable and
(y) the terms and conditions of any agreements governing such assets (or the operation thereof or the holders thereof) at such time. Any Partnership assets distributed in kind will first be written up or down to their Fair Market Value, thus
creating Profit or Loss (if any), which shall be allocated in accordance with Section 7. The Liquidator shall determine the Fair Market Value of any property distributed in accordance with the valuation procedures set forth in Section 13.

  

	11.6	 Termination Upon completion of the Distribution of the assets of the Partnership as provided in
Section 11.4.3(c) hereof, the Partnership shall be terminated and the Liquidator shall take such other actions as may be necessary to terminate the Partnership. 

  
 51 

	11.7	 Survival of Rights, Duties and Obligations Dissolution, liquidation, winding up or termination of the
Partnership for any reason shall not release any party from any Losses which at the time of such dissolution, liquidation, winding up or termination already had accrued to any other party or which thereafter may accrue in respect of any act or
omission prior to such dissolution, liquidation, winding up or termination. For the avoidance of doubt, none of the foregoing shall replace, diminish or otherwise adversely affect any Partner’s right to indemnification pursuant to
Section 12. 

  

	11.8	 Recourse for Claims Each Partner shall look solely to the assets of the Partnership for all
Distributions with respect to the Partnership, such Partner’s Capital Account, and such Partner’s share of Profit or Loss and other items of income, gain, loss and deduction, and shall have no recourse therefor (upon dissolution or
otherwise) against the General Partner, the Liquidator or any other Partner. No Partner shall have any right to demand or receive property other than cash upon dissolution and liquidation of the Partnership. 

 

	11.9	 Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the
provisions of Sections 7.6, 12.1, 12.2, and 14.10 shall survive the termination of the Partnership. 

 SECTION 12

 LIABILITY AND INDEMNIFICATION 
  

	12.1	 Limitation of Liability 

 

	12.1.1	 To the extent permissible by law, each of the Partners and the Partnership hereby waives any and all fiduciary
duties that, absent such waiver, may be implied by Applicable Law, and in doing so, acknowledges and agrees that the duties and obligation of each Covered Person to each other and to the Partnership are, to the extent permissible by law, only as
expressly set forth in this Agreement. To the extent permissible by law, the provisions of this Agreement, to the extent that they restrict the duties and liabilities of a Covered Person otherwise existing at law or in equity, are agreed by the
Partners to replace such other duties and liabilities of such Covered Person. 

  

	12.1.2	 To the fullest extent permitted by law, no Partner or Continuing Partner Representative shall have duties
(including fiduciary duties) to any of the Partners or to the Partnership, and in doing so, recognize, acknowledge and agree that their duties and obligations to one another and to the Partnership are only as expressly set forth in this Agreement;
provided, however, that each Partner shall have the duty to act in accordance with the implied contractual covenant of good faith and fair dealing. 

 

	12.1.3	 To the extent that, at law or in equity, any Partner (including PubCo) or the Continuing Partner Representative
has any duties (including fiduciary duties) and liabilities relating thereto to the Partnership, to another Partner or to another Person who is a party to or is otherwise bound by this Agreement, none of the Partners (including PubCo) or the
Continuing Partner Representative acting under this Agreement will, to the extent permitted by law, be liable to the Partnership, to any such other Partner or to any such other Person who is a party to or is otherwise bound by this Agreement, for
their good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Partner (including PubCo) or Continuing Partner
Representative otherwise existing at law or in equity, are agreed by the Partners to replace to that extent such other duties and liabilities of the Partners or Continuing Partner Representative relating thereto (including PubCo).

  
 52 

	12.1.4	 The General Partner may consult with legal counsel, accountants and financial or other advisors selected by it,
and any act or omission taken by the General Partner on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reliance upon and in accordance with the advice of such Person as to matters the General Partner
reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion or advice, and the General Partner will be fully
protected in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care. 

  

	12.1.5	 For the purposes of this Section 12.1.5, a “Business Opportunities Exempt Party” shall be
(a) any Partner that is not a director, manager, officer or employee of the General Partner, PubCo or any of their respective Subsidiaries, in which case solely acting in their capacity as such, (b) any of their respective Affiliates
(other than the Partnership, PubCo or any of their respective Subsidiaries), (c) any Person that was a Partner immediately before the Effective Time or any of its respective Affiliates (including its respective investors and equityholders and any
associated Persons or investment funds or any of their respective portfolio companies or investments) or (d) any of the respective officers, managers, directors, agents, shareholders, Partners, and partners of any of the foregoing (but in each
case excluding any director, manager, officer or employee of the General Partner, PubCo or any of their respective Subsidiaries solely acting in their capacity as such). The Partnership and each of the Partners, on its own behalf and on behalf of
their respective Affiliates and equityholders, hereby renounces any interest or expectancy of the Partnership in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to any Business
Opportunities Exempt Party and irrevocably waives any right to require any Business Opportunity Exempt Party to act in a manner inconsistent with the provisions of this Section 12.1.5. No Business Opportunities Exempt Party
who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for PubCo, the Partnership or any of their respective Subsidiaries, Affiliates or equityholders shall have any duty to communicate
or offer such opportunity to the Partnership and none of PubCo, the Partnership or any of their respective Subsidiaries, Affiliates or equityholders will acquire or be entitled to any interest or participation in any such transaction, agreement,
arrangement or other matter or opportunity as a result of participation therein by a Business Opportunity Exempt Party. This Section 12.1.5 shall not apply to, and no interest or expectancy of the Partnership is renounced
with respect to, any opportunity offered to any director or officer of PubCo or its Subsidiaries if such opportunity is expressly offered or presented to, or acquired or developed by, such Person solely in his or her capacity as a director or
officer of PubCo or its Subsidiaries. No amendment or repeal of this Section 12.1.5 shall apply to or have any effect on the liability or alleged liability of any Business Opportunities Exempt Party for or with respect to
any opportunities of which any such Business Opportunities Exempt Party becomes aware prior to such amendment or repeal. Any Person purchasing or otherwise acquiring any interest in any Units shall be deemed to have notice of and consented to the
provisions of this Section 12.1.5. Neither the amendment or repeal of this Section 12.1.5, nor the adoption of any provision of this Agreement inconsistent with this
Section 12.1.5, shall eliminate or reduce the effect of this Section 12.1.5 in respect of any business opportunity first identified or any other matter occurring, or any cause of action that, but
for this Section 12.1.5, would accrue or arise, prior to such amendment, repeal or adoption. No action or inaction taken by any Business Opportunities Exempt Party in a manner consistent with this
Section 12.1.5 shall be deemed to be a violation of any fiduciary or other duty owed to any Person. 

  
 53 

	12.2	 Indemnification. 

 

	12.2.1	 Exculpation and Indemnification. Notwithstanding any other provision of this Agreement, whether express
or implied, to the fullest extent permitted by law, no Indemnitee shall be liable to the Partnership or any Partner for any act or omission in relation to the Partnership or this Agreement or any transaction contemplated hereby taken or omitted by
an Indemnitee unless such Indemnitee’s conduct constituted fraud, bad faith or willful misconduct. To the fullest extent permitted by law, as the same exists or hereafter be amended (but in the case of any such amendment, only to the extent
that such amendment permits the Partnership to provide broader indemnification rights than such law permitted the Partnership to provide prior to such amendment), the Partnership shall indemnify any Indemnitee who was or is made or is threatened to
be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Partnership or otherwise), whether civil, criminal, administrative, arbitrative or investigative, and whether
formal or informal (hereinafter a “Proceeding”), including appeals, by reason of his or her or its status as an Indemnitee or by reason of any action alleged to have been taken or omitted to be taken by Indemnitee in such capacity,
for and against all loss and liability suffered and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by such Indemnitee in connection with such action, suit or proceeding, including
appeals; provided that such Indemnitee shall not be entitled to indemnification hereunder if, but only to the extent that, such Indemnitee’s conduct constituted fraud, bad faith or willful misconduct. Notwithstanding the preceding sentence,
except as otherwise provided in Section 12.2.3, the Partnership shall be required to indemnify an Indemnitee in connection with any action, suit or proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of
such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the General Partner, and (ii) by or in the right of the Partnership only if the General Partner has provided its prior written consent. The indemnification
of an Indemnitee of the type identified in clause (d) of the definition of Indemnitee shall be secondary to any and all indemnification to which such Indemnitee is entitled from the relevant other Person (including any payment made to such
Indemnitee under any insurance policy issued to or for the benefit of such Person or Indemnitee) (the “Primary Indemnification”), and will only be paid to the extent the Primary Indemnification is not paid and/or does not provide
coverage (e.g., a self-insured retention amount under an insurance policy). No such Person shall be entitled to contribution or indemnification from or subrogation against the Partnership. The indemnification of any other Indemnitee shall, to the
extent not in conflict with such policy, be secondary to any and all payment to which such Indemnitee is entitled from any relevant insurance policy issued to or for the benefit of the Partnership or any Indemnitee. 

 

	12.2.2	 Advancement of Expenses. To the fullest extent permitted by law, the Partnership shall promptly pay
reasonable expenses (including attorneys’ fees) incurred by any Indemnitee in appearing at, participating in or defending any Proceeding in advance of the final disposition of such Proceeding, including appeals, upon presentation of an
undertaking on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Section 12.2 or otherwise. Notwithstanding the preceding
sentence, except as otherwise provided in Section 12.2.3, the Partnership shall be required to pay expenses of an Indemnitee in connection with any Proceeding (or part thereof) (i) commenced by such Indemnitee only if
the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the General Partner and (ii) by or in the right of the Partnership only if the General Partner has provided its prior written consent.

  

	12.2.3	 Unpaid Claims. If a claim for indemnification (following the final disposition of such Proceeding) or
advancement of expenses under this Section 12.2 is not paid in full within 30 days after a written claim therefor by any Indemnitee has been received by the Partnership, such Indemnitee may file proceedings to recover the
unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Partnership shall have the burden of proving that such Indemnitee is not entitled to the
requested indemnification or advancement of expenses under applicable Law. 

  
 54 

	12.2.4	 Insurance. 

  

	 	(i)	 To the fullest extent permitted by law, the Partnership may purchase and maintain insurance on behalf of any
Person described in Section 12.2.1 against any liability asserted against such person, whether or not the Partnership would have the power to indemnify such person against such liability under the provisions of this
Section 12.2 or otherwise. 

  

	 	(ii)	 In the event of any payment by the Partnership under this Section 12.2, the
Partnership shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee from any relevant other Person or under any insurance policy issued to or for the benefit of the Partnership, such relevant other
Person, or any Indemnitee. Each Indemnitee agrees to execute all papers required and take all action necessary to secure such rights, including the execution of such documents as are necessary to enable the Partnership to bring suit to enforce any
such rights in accordance with the terms of such insurance policy or other relevant document. The Partnership shall pay or reimburse all expenses actually and reasonably incurred by the Indemnitee in connection with such subrogation.

  

	 	(iii)	 The Partnership shall not be liable under this Section 12.2 to make any payment of
amounts otherwise indemnifiable hereunder (including judgments, fines and amounts paid in settlement, and excise taxes with respect to an employee benefit plan or penalties) if and to the extent that the applicable Indemnitee has otherwise actually
received such payment under this Section 12.2 or any insurance policy, contract, agreement or otherwise. 

  

	12.2.5	 Non-Exclusivity of Rights. The provisions of this
Section 12.2 shall be applicable to all actions, claims, suits or proceedings made or commenced after the date of this Agreement, whether arising from acts or omissions to act occurring before or after its adoption. The provisions of this
Section 12.2 shall be deemed to be a contract between the Partnership and each person entitled to indemnification under this Section 12.2 (or legal representative thereof) who serves in such capacity at any time while this
Section 12.2 and the relevant provisions of applicable Law, if any, are in effect, and any amendment, modification or repeal hereof shall not affect any rights or obligations then existing with respect to any state of facts or any action, suit
or proceeding then or theretofore existing, or any action, suit or proceeding thereafter brought or threatened based in whole or in part on any such state of facts. If any provision of this Section 12.2 shall be found to be invalid or limited
in application by reason of any Law or regulation, it shall not affect the validity of the remaining provisions hereof. The rights of indemnification provided in this Section 12.2 shall neither be exclusive of, nor be deemed in limitation of,
any rights to which any person may otherwise be or become entitled or permitted by contract, this Agreement or as a matter of law, both as to actions in such person’s official capacity and actions in any other capacity, it being the policy of
the Partnership that indemnification of any person whom the Partnership is obligated to indemnify pursuant to Section 12.2.1 shall be made to the fullest extent permitted by law. 

  
 55 

	12.2.6	 For purposes of this Section 12.2, references to “other enterprises”
shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Partnership”
shall include any service as a director, officer, employee or agent of the General Partner (if engaged by the General Partner in its capacity as general partner of the Partnership) or as an employee or agent of the Partnership which imposes duties
on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries. 

  

	12.2.7	 This Section 12.2 shall not limit the right of the Partnership, to the extent and in
the manner permitted by law, to indemnify and to advance expenses to, and purchase and maintain insurance on behalf of, persons other than persons described in Section 12.2.1. 

 

	12.3	 Survival. The provisions of this Section 12 shall survive the dissolution, liquidation, winding up
and termination of the Partnership. 

 SECTION 13 

VALUATION 
  

	13.1	 Fair Market Value For all purposes of this Agreement, “Fair Market Value” of any
asset, property or equity interest means the amount which a seller of such asset, property or equity interest would receive in a sale of such asset, property or equity interest in an arms-length transaction with an unaffiliated third party
consummated on a date determined by the General Partner (which may be the date on which the event occurred which necessitated the determination of the Fair Market Value) (and after giving effect to any transfer taxes payable in connection with such
sale). 

  

	13.2	 Determination Fair Market Value shall be determined by the General Partner (or, if pursuant to
Section 11.4, the Liquidator) in its good faith judgment in such manner as it deems reasonable and using all factors, information and data deemed to be pertinent; provided that, no determination of Fair Market Value
shall give effect or take into account any “minority discount” or “liquidity discount” (or any similar discount arising out of the fact that the Units are restricted or is not registered with the Commission, publicly traded or
listed on a securities exchange), but shall value the Partnership and its Subsidiaries and their respective businesses in their entirety on an enterprise basis using any variety of industry recognized valuation techniques commonly used to value
businesses.

the parties thereto, the parties expressly agree that all the terms and provisions hereof shall be governed by and construed in accordance with the laws of the Ireland. The courts of Ireland shall have
non-exclusive jurisdiction to hear and determine any claim, suit, action or proceeding, and to settle any disputes, which may arise out of or are in any way related to or in connection with this Agreement,

	14.12	 Amendments and Waivers  

 

	14.12.1	 Amendments by General Partner with Approval of PubCo This Agreement (including the Annexes hereto) may
be amended, supplemented, waived or modified by the General Partner with the approval of PubCo (with the approval of a majority of the disinterested members of the PubCo Board) and without the approval of any other Partner or other Person so long as
such amendment is executed and delivered to the Partnership by PubCo and has been approved by the General Partner and each of the Limited Partners (other than PubCo) hereby appoints the General Partner as its lawful attorney for the purposes of
executing and delivering such amendment on its behalf; provided that, no amendment, including any amendment effected by way of merger, consolidation or Transfer of all or substantially all the assets of the Partnership, may (i) materially and
adversely affect the rights of a holder of Units, as such, other than on a pro rata basis with other holders of Units of the same Class without the consent of such holder (or, if there is more than one such holder that is so affected,
without the consent of a majority in interest of such affected holders in accordance with their holdings of such Class of Units); provided that, the creation or issuance of any new Unit or Equity Interest of the Partnership permitted pursuant
to Section 9.5 and any amendments or modifications to Agreement to the extent necessary to reflect such creation or issuance shall not be deemed to disproportionately and adversely affect a Partner or remove a right or privilege specifically
granted to a Partner in any event; (ii) modify the limited liability of any Partner, or increase the Liabilities of any Partner, in each case, without the prior written consent of each such affected Partner; or (iii) alter or change any
rights, preferences or privileges of any Units in a manner that is different or prejudicial relative to any other Units in the same class of Units, without the prior written consent of the holders of a majority of such Units. 

 

	14.12.2	 Amendments by General Partner Without Approval of Other Persons Notwithstanding anything to the contrary
herein, the General Partner may, without the written consent of any Partner, amend, supplement, waive or modify any provision of this Agreement, including Schedule I, and execute, swear to, acknowledge, deliver, file and record whatever documents
may be required in connection therewith, to reflect: 

 (a) any amendment, supplement, waiver or
modification that the General Partner determines in its reasonable discretion to be necessary or appropriate in connection with the creation, authorization or issuance of Units or any Class or series of equity interest in the Partnership
pursuant to Section 9.1 hereof; 
 (b) the admission, substitution, or withdrawal of Partners in accordance with this
Agreement, pursuant to Sections 10.6 and 10.7 hereof; 
 (c) a change in the name of the Partnership, the location of the
principal place of business of the Partnership, the registered agent of the Partnership or the registered office of the Partnership (whether to a location in Ireland or outside Ireland); 

(d) any amendment, supplement, waiver or modification that the General Partner determines in its reasonable discretion to be
necessary or appropriate to address changes in U.S. federal income tax regulations, legislation or interpretation or Irish tax regulations, legislation or interpretation; and/or 

(e) a change in the Fiscal Year or taxable year of the Partnership and any other changes that the General Partner determines to
be necessary or appropriate as a result of a change in the Fiscal Year or taxable year of the Partnership including a change in the dates on which Distributions are to be made by the Partnership. 

  
 60 

 If an amendment has been approved in accordance with this Agreement, such amendment shall be
adopted and effective with respect to all Partners. Upon obtaining such approvals as may be required by this Agreement, and without further action or execution on the part of any Partner or other Person, any amendment to this Agreement may be
implemented and reflected in a writing executed solely by the General Partner and the Partners shall be deemed a party to and bound by such amendment. 
  

	14.12.3	 Failure to Act not a Waiving of Rights No failure or delay by any party in exercising any right, power
or privilege hereunder (other than a failure or delay beyond a period of time specified herein) shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law. 

  

	14.12.4	 Waiving of Certain Rights Except as may be otherwise required by law in connection with the winding-up, liquidation, or dissolution of the Partnership, each Partner hereby irrevocably waives any and all rights that it may have to maintain an action for judicial accounting or for partition of any of the
Partnership’s property. 

  

	14.13	 No Third Party Beneficiaries This Agreement shall be binding upon and inure solely to the benefit of the
parties hereto and their permitted assigns and successors and nothing herein, express or implied, is intended to or shall confer upon any other Person or entity, any legal or equitable right, benefit or remedy of any nature whatsoever under or by
reason of this Agreement (other than pursuant to Section 12.2 hereof). 

  

	14.14	 Power of Attorney Each Partner, by its execution hereof, hereby makes, constitutes and appoints the
General Partner as its true and lawful agent and attorney in fact, with full power of substitution and full power and authority in its name, place and stead, to make, execute, sign, acknowledge, swear to, record and file (a) this Agreement and
any amendment to this Agreement that has been consented to and adopted as herein provided; (b) all certificates and other instruments (including consents and ratifications which the Partners have agreed to provide upon a matter receiving the
agreed support of Partners) deemed advisable by the General Partner to carry out the provisions of this Agreement and Law or to permit the Partnership to continue as a limited partnership wherein the Partners have limited liability in each
jurisdiction where the Partnership may be doing business; (c) all instruments that the General Partner deems appropriate to reflect a change or modification of this Agreement or the Partnership in accordance with this Agreement, including the
admission of additional Partners or substituted Partners pursuant to the provisions of this Agreement; (d) all conveyances and other instruments or papers deemed advisable by the General Partner to effect the liquidation and termination of the
Partnership in accordance with this Agreement; and (e) all assumed name certificates required or permitted (in light of the Partnership’s activities) to be filed on behalf of the Partnership. 

 

	14.15	 Separate Agreements; Schedules Notwithstanding any other provision of this Agreement, including
Section 14.12, the General Partner in its sole discretion may, or may cause the Partnership to, without the approval of any Partner or other Person, enter into separate subscription, letter or other agreements with individual Partners that have
become or will become Partners after the date hereof with respect to any matter, which have the effect of establishing rights under, or altering, supplementing or amending the terms of, this Agreement. The parties hereto agree that any terms
contained in any such separate agreement shall govern with respect to such future Partner(s) party thereto notwithstanding the provisions of this 

  
 61 

	 	
Agreement. The General Partner in its sole discretion may from time to time execute and deliver to the Partners schedules which set forth information contained in the books and records of the
Partnership and any other matters deemed appropriate by the General Partner. Such schedules shall be for information purposes only and shall not be deemed to be part of this Agreement for any purpose whatsoever. Notwithstanding anything to the
contrary, solely for U.S. federal income tax purposes, this Agreement, the Tax Receivable Agreement, the Exchange Agreement and any other separate agreement described in this Section 14.15 shall constitute a “partnership agreement”
within the meaning of Section 761 of the Code. 

  

	14.16	 Delivery by Facsimile or Email This Agreement, the agreements referred to herein, and each other
agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine or email with scan or facsimile
attachment, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to
any such agreement or instrument shall raise the use of a facsimile machine or email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or email as
a defence to the formation or enforceability of a contract, and each such party forever waives any such defence. 

  

	14.17	 Registration of changes in the Partnership The General Partner shall ensure that all necessary returns
(other than tax returns under Section 8.2), filings and registrations required to be made by or on behalf of the Partnership are made in the manner and time required by the Act and the other Partners agree to complete or provide the necessary

regard. Notwithstanding any other provision of this Agreement, to the extent required by the Act, if any change is made or occurs in (a) the name of the Partnership, (b) the general nature of the business of the Partnership, (c) the
principal place of business of the Partnership, (d) the Partners or the name of any Partner, (e) the term or character of the Partnership, (f) the sum contributed by any Limited Partner or (g) the liability of any Partner by
reason of its becoming a limited instead of a general partner under the Act or a general instead of a limited partner under the Act, such change shall only take effect from the date a statement of the change, signed by, or on behalf of, the General
