 AGREEMENT 

NOW, THEREFORE, in consideration of the mutual covenants rights and obligations set forth in this Amendment and the LLC Agreement, the
benefits to be derived therefrom, and other good and valuable consideration, the receipt and the sufficiency of which each party hereto acknowledges, each party hereto, by execution of this Amendment, hereby agrees as follows: 

1.01 Defined Terms. Capitalized terms used but not defined in this Amendment shall have the meanings ascribed to such
terms in the LLC Agreement. 
 1.02 Amendments to the LLC Agreement. 

(a) Effective as of the Effective Date, Section 3.1(c)(iv)(D) of the LLC Agreement is hereby deleted in its entirety and replaced with the
following: 












 “(D) “Class B
Proceeds” means the sum of (I) the aggregate amount of cash which the Partners Group Members receive in respect of their Units as a result of a Transfer thereof or a distribution with respect thereto (other than
(1) as management fees from the Company or any of its Subsidiaries, (2) any reimbursements of transaction or other expenses incurred by and payable directly by Partners Group Members, (3) the transaction fee payable upon the
consummation of the transactions contemplated by the Purchase Agreement, (4) any Tax Distributions or (5) any securities distributed to the Members in connection with a Public Offering of the Company or any of its Subsidiaries or
otherwise), and (II) in the event that the Company distributes the stock of a Corporate Vehicle to the Members in connection with a Conversion contemplated by Section 10.4 in accordance with
Section 5.2 (any such distribution, a “Conversion Distribution”), an amount equal to the aggregate Fair Market Value of the shares of the stock of such Corporate Vehicle distributed to the Partners Group
Members in respect of their Units in such Conversion Distribution, determined based on the per share offering price of the stock of such Corporate Vehicle in the applicable Public Offering, net of underwriting discounts and commissions. For the
avoidance of doubt, (i) in the event the Partners Group Members receive consideration other than cash in any distribution, other than a Conversion Distribution, such amount shall not be included in determining whether the Class B-2 Performance Hurdle or Class B-3 Performance Hurdle has been met until such consideration (or any successor consideration that is not cash or cash
equivalents) has been converted to cash and received by the Partners Group Members free and clear of any restriction, such additional proceeds shall then be included in determining whether the Class B-2
Performance Hurdle or the Class B-3 Performance Hurdle has been met, whereupon the vesting of the Class B-2 and
Class B-3 Units hereunder, whether or not then outstanding, shall be redetermined and upon such redetermination such Class B Proceeds and any other distributions that would have been made to the
holders or former holders of such Class B-2 and Class B-3 Units shall be distributed or paid to the Persons entitled thereto in accordance with
Section 5.2 by the Company or the Partners Group Members, as the case may be, to the holders or former holders of such Class B-2 and
Class B-3 Units as if such Units had been vested upon the closing of such distribution had such additional Class B Proceeds then been paid to such holders, and (ii) in the event that a
Class B Distribution Event involves an escrow, indemnification obligations, deferred payments or contingent payments, and upon resolution thereof additional Class B Proceeds are payable to the Partners Group Members, such proceeds shall
then be included in determining whether the Class B-2 Performance Hurdle or the Class B-3 Performance Hurdle has been met, whereupon the vesting of the Class B-2 and Class B-3 Units hereunder, whether or not then outstanding, shall be redetermined and upon such redetermination such Class B Proceeds and any
other distributions that would have been made to the holders or former holders of such Class B-2 and Class B-3 Units shall be distributed in accordance with
Section 5.2 by the Company or the Partners Group Members, as the case may be, to the holders or former holders of such Class B-2 and
Class B-3 Units as if such Units had been vested upon the closing of such Class B Distribution Event had such additional proceeds then been paid to such holders.” 

(b) Effective as of the Effective Date, the following is hereby added to Section 5.2(a) of the LLC Agreement as a new sentence at the end
of Section 5.2(a) of the LLC Agreement: 
 “Notwithstanding anything in this Section 5.2
to the contrary, in the event that the Company distributes the stock of a Corporate Vehicle to the Members in connection with a Conversion contemplated by Section 10.4 in accordance with this
Section 5.2, the Board may determine to (A) distribute shares of such stock that are “substituted basis property” with respect to the “section 704(c) property” originally contributed to the Company
by a Member, each within the meaning of Treasury Regulation Section 1.704-3(a)(8), first only to such Member before distributing such shares to any other Members and (B) distribute the remaining
shares of such stock (i.e., that are not “substituted basis property” with respect to “section 704(c) property” that was originally contributed to the Company) in accordance with this Section 5.2(a)
first only to Members other than such Member before distributing any remaining shares to such Member; provided that, for the avoidance of doubt, any such determination by the Board shall not affect the total number of shares of such stock
that any Member is entitled to receive in such distribution in accordance with the order of priority set forth in this Section 5.2(a).”

 1.03 Continued Effect. Except to the extent expressly amended hereby,
all terms, conditions, covenants, representations and warranties of the LLC Agreement shall continue in full force and effect and the LLC Agreement shall remain enforceable and binding in accordance with its terms. This Amendment shall become a part
of the LLC Agreement as if set forth in full therein and references to the Agreement shall be to the Agreement as amended by this Amendment. 

1.04 Authorization of Substitute Pages. The Company, by approval of this Amendment, authorizes the law firm of
Latham & Watkins LLP to insert substitute pages into the LLC Agreement which reflect the Amendments set forth herein. 
 1.05
Miscellaneous. 
 (a) Governing Law. This Amendment shall be construed in accordance with and governed by the internal
laws of the State of Delaware, without regard to the principles of conflicts or choice of laws thereof that would give rise to the application of the domestic substantive law of any other jurisdiction. 

(b) Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY ACTION OR OTHER
PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT. 
 (c) Binding Effect. This Amendment shall be binding upon and shall inure to
the benefit of the Company and the Members and their respective successors and permitted assigns. 
 (d) Counterpart Execution; Fax
Signatures. This Amendment may be executed in any number of counterparts, each of which, when so executed and delivered, shall be an original, but all of which together shall constitute one agreement binding on the parties hereto. Transmission
of an executed counterpart by fax or PDF file of this Amendment shall be deemed to constitute due and sufficient delivery of such counterpart, and such signatures shall be deemed original signatures for purposes of the enforcement and construction
of this Amendment. 
 (e) Incorporation by Reference. Sections 1.2 (Rules of Interpretation), 13.4 (Equitable Remedies),
13.7 (Severability), 13.8 (Headings) and 13.15 (Consent to the Exclusive Jurisdiction of the Courts of Delaware) of the LLC Agreement are hereby incorporated by reference as if set forth herein, mutatis mutandis.
