next succeeding calendar month after such change of election is made. For the avoidance of doubt, the Parties acknowledge and agree that
the Manager’s previous and ongoing election in connection with the Previous Agreement to invest 100% of any and all Base Management
Fees to which the Manager is entitled in Common Stock remains in full force and effect and shall apply to any and all Base Management

anything in this Section 7.2(e) to the contrary, in the event that (x) the Manager has determined to invest all or any
portion of its Base Management Fee for any calendar month in Company Common Units, and (y) the Base Fee VWAP for such calendar month

    19

     

    

 

(A)            in
the event the Manager previously had determined to invest 100% of its Base Management Fee for such calendar month in Company Common Units,
then the Manager instead shall (x) receive from the Company cash in an amount (the “Full Base Fee Cash Amount”)
equal to the product of such Base Management Fee multiplied by a fraction, the numerator of which shall be the excess of the Base Fee
VWAP over the Threshold Price, and the denominator of which shall be the Base Fee VWAP, and (y) invest the remainder of such Base
Management Fee (excluding the Full Base Fee Cash Amount) in Company Common Units as contemplated by the preceding clauses (i) and
(ii); and

 

(B)            in
the event the Manager previously had determined to invest any portion (less than 100%) of its Base Management Fee for such calendar month
in Company Common Units, then, in lieu of such investment, the Manager instead shall (x) receive from the Company cash in an amount
(the “Partial Base Fee Cash Amount”) equal to the product of such portion of its Base Management Fee multiplied
by a fraction, the numerator of which shall be the excess of the Base Fee VWAP over the Threshold Price, and the denominator of which
shall be the Base Fee VWAP, and (y) invest the remainder of such portion of its Base Management Fee (excluding the Partial Base

Business Days after that Fiscal Quarter End Date.

 

(c) The Performance Fee
calculated pursuant to Section 7.3(b) above will be allocated between the Company and the Managed Subsidiaries in accordance
with the Company’s corporate allocation policy and otherwise in accordance with GAAP.

 

(d) The Performance Fee,
if any, to which the Manager is entitled under this Section 7.3 is due in cash (subject to Section 7.3(e)) as of the Fiscal
Quarter End Date of the relevant Fiscal Quarter and shall be settled by the Company and the Managed Subsidiaries (in accordance with
the allocation pursuant to Section 7.3(c) above) within 10 Business Days of receipt by the Company of notification pursuant
to Section 7.3(b).

 

(e) The Manager has the
right but not the obligation to invest all or a portion of the Performance Fee to which the Manager is entitled under this Section 7.3
in Company Common Units.

 

(i) If the
Manager determines to invest all or any portion of its Performance Fee with respect to a Fiscal Quarter in Company Common Units, the
Manager shall be entitled to purchase, upon payment and subject to clause (iii) below, that number of Company Common Units equal
to such amount of the Performance Fee calculated pursuant to Section 7.3(b), divided by the volume weighted average trading price
of a Company Common Unit during the period commencing on and including the first Trading Day of the last calendar month of the relevant
Fiscal Quarter and ending on and including the last Trading Day of such calendar month (such volume weighted average trading price, the
 “Performance Fee VWAP”).

 

    20

     

    

 

(ii) In the
event the Manager determines to invest all or any portion of its Performance Fee for any Fiscal Quarter in Company Common Units, it shall
notify the Company and the Compensation Committee of the percentage of the Performance Fee to be invested in Company Common Units during
the Election Period immediately preceding the Fiscal Quarter End Date for such Fiscal Quarter (subject to the third sentence of this
Section 7.3(e)(ii)). Such Company Common Units shall be issued to the Manager in accordance with Section 7.3(d). Any election
made by the Manager during any Election Period pursuant to this Section 7.3(e)(ii) shall be effective beginning with the fiscal
quarter after such change of election is made and shall remain in effect for all subsequent Election Periods unless and until the Manager
affirmatively changes in a timely manner such election in any subsequent Election Period for the next succeeding Fiscal Quarter after
such change of election is made. For the avoidance of doubt, the Parties acknowledge and agree that the Manager’s previous and
ongoing election in connection with the Previous Agreement to invest 100% of any and all Performance Fees to which the Manager is entitled
in Common Stock remains in full force and effect and shall apply to any and all Performance Fees to which the Manager becomes entitled
hereunder after the date hereof, until such election is changed in accordance with the preceding sentence; it being understood that following
the Reorganization such election shall be an election to invest in Company Common Units.

 

(iii) Notwithstanding
anything in this Section 7.3(e) to the contrary, in the event that (x) the Manager has determined to invest all or any
portion of its Performance Fee with respect to a Fiscal Quarter in Company Common Units, and (y) the Performance Fee VWAP for such
Fiscal Quarter exceeds the Threshold Price, then:

 

(A) in the event
the Manager previously had determined to invest 100% of its Performance Fee for such Fiscal Quarter in Company Common Units, then the
Manager instead shall (x) receive from the Company cash in an amount (the “Full Performance Fee Cash Amount”)
equal to the product of such Performance Fee multiplied by a fraction, the numerator of which shall be the excess of the Performance
Fee VWAP over the Threshold Price, and the denominator of which shall be the Performance Fee VWAP, and (y) invest the remainder
of such Performance Fee (excluding the Full Performance Fee Cash Amount) in Company Common Units as contemplated by the preceding clauses
(i) and (ii); and

 

(B) in the event
the Manager previously had determined to invest any portion (less than 100%) of its Performance Fee for such Fiscal Quarter in Company

Performance Fee Cash Amount”) equal to the product of such portion of its Performance Fee multiplied by a fraction, the
numerator of which shall be the excess of the Performance Fee VWAP over the Threshold Price, and the denominator of which shall be the
Performance Fee VWAP, and (y) invest the remainder of such portion of its Performance Fee (excluding the Partial Performance Fee
Cash Amount) in Company Common Units as contemplated by the preceding clauses (i) and (ii).

 

(f) The Manager will notify
the Company and the Compensation Committee of the Net Equity Value, Foreign Net Equity Value and U.S. Net Equity Value, and the calculations

of the Fiscal Quarter End Date for the immediately prior Fiscal Quarter.

 

(g) The Manager will notify
the Company and the Compensation Committee of the Additional Offering Foreign Net Equity Value and Additional Offering U.S. Net Equity

INDEMNITY

 

Section 11.1 Indemnification
of Manager. The Company and each Managed Subsidiary, jointly and severally, agrees to indemnify the Manager, any controlling person
of the Manager, and each of their respective directors, officers, employees, agents, Affiliates and representatives (each, an “Indemnified
Party”) and hold each of them harmless against any and all losses, (including lost profits) claims, damages, expenses or
liabilities, joint or several (collectively, “Liabilities”), to which the Indemnified Parties may become liable,
directly or indirectly, arising out of, or relating to, this Agreement, unless it is finally judicially determined that the Liabilities
resulted from the gross negligence, willful misconduct, bad faith or reckless disregard of duty of any Indemnified Party or fraudulent
or dishonest acts of such Indemnified Party. The Company and the Managed Subsidiaries further agree to reimburse each Indemnified Party
immediately upon request for all expenses (including reasonable attorneys’ fees and expenses) as they are incurred in connection
with the investigation of, preparation for, defense of, or providing evidence in any action, claim, suit, proceeding or investigation,
directly or indirectly, arising out of, or relating to, this Agreement or the Manager’s services hereunder, whether or not pending
or threatened and whether or not any Indemnified Party is a party to such proceeding. The Company and the Managed Subsidiaries also agree
that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company, the
Managed Subsidiaries, or any person asserting claims on behalf of or in right of the Company or the Managed Subsidiaries, directly or
indirectly, arising out of, or relating to, this Agreement or the Manager’s services thereunder, unless it is finally judicially
determined that such Liability resulted from the gross negligence, willful misconduct, bad faith or reckless disregard of duty of such
Indemnified Party or fraudulent or dishonest acts of such Indemnified Party. Moreover, in no event, regardless of the legal theory advanced,
shall any Indemnified Party be liable to the Company, the Managed Subsidiaries, or any person asserting claims on behalf of or in the
right of the Company or the Managed Subsidiaries for any consequential, indirect, incidental or special damages of any nature. In the
event that an Indemnified Party is requested or required to appear as a witness in any action brought by or on behalf of or against the
Company or the Managed Subsidiaries or any Affiliate of the Company or the Managed Subsidiaries in which such Indemnified Party is not
named as a defendant, the Company and the Managed Subsidiaries agree to reimburse the Manager for all expenses incurred by it in connection
with such Indemnified Party’s appearing and preparing to appear as such a witness, including, without limitation, the reasonable
fees and disbursements of its legal counsel.

 

The Company and the Managed
Subsidiaries agree that, without the Manager’s prior written consent, they will not settle, compromise or consent to the entry
of any judgment in or otherwise seek to terminate any claim, action, suit, proceeding or investigation in respect of which indemnification
could be sought hereunder (whether or not the Manager or any other Indemnified Party is an actual or potential party to such claim, action,
suit, proceeding or investigation), unless (a) such settlement, compromise, consent or termination includes an unconditional release
of each Indemnified Party from any liabilities arising out of such claim action, suit, proceeding or investigation and (b) the parties
agree that the terms of such settlement shall remain confidential.

 

    27

     

    

 

Section 11.2 Indemnification
of Company. The Manager agrees to indemnify the Company and hold it harmless against any Liabilities to the same extent as the foregoing
indemnity from the Company and the Managed Subsidiaries to the Manager, but only insofar as it is finally judicially determined that
the Liabilities arose out of or were based on the gross negligence, willful misconduct, bad faith or reckless disregard of duty of the
Manager in the performance of its duties under this Agreement or its fraudulent or dishonest acts.

 

Section 11.3 Indemnification.
The rights of the Indemnified Parties referred to above shall be in addition to any rights that any Indemnified Party may otherwise have.
The indemnities referred to in this Article XI survive the termination of this Agreement.

 

Article XII

Subsidiaries (including, without limitation, by reason of the purchase, sale or retention of any security) in connection with the performance
of the Manager’s duties under this Agreement, except for a loss resulting from gross negligence, willful misconduct or bad faith

Manager believes in good faith to be the original or a copy of an appointment by a Stockholder in respect of a Company Common Unit or
holder of a Certificate in respect of a Company Common Unit of a person to act as their agent for any purpose connected with the Company;
and

 

(d) any other document
provided to the Manager in connection with the Company upon which it is reasonable for the Manager to rely;
