Net Assets

The Partnership, at the discretion of the General Partner, has the authority to issue an unlimited number of Units of each

Unit Class (as defined below).

The Partnership has fourteen classes of limited partnership units (the “Units”): Class A-1a, Class A-1b, Class A-1c, Class

D-1, Class D-2, Class F-1, Class F-2, Class F-3, Class F-4, Class I-1, Class I-2, Class S-1, Class S-2 and Class X (each a “Unit

Class” or a “Class”). The purchase price per Unit of each Class is equal to the transactional NAV per Unit (i.e., the price at

which transactions in the Partnership’s Units are made) for such Class as of the last calendar day of the immediately preceding

month. Before the Partnership had determined its first transactional NAV, the subscription price for Units was $25.00 per Unit

plus applicable Subscription Fees. The Partnership will only accept subscriptions as of the first business day of each month (a

“Subscription Date”), unless the General Partner determines otherwise. There are variations between these Unit Classes

including Subscription Fees, Servicing Fees, Management Fees and minimum investment limits.

On December 31, 2024, the General Partner invested $1,000 for no Units as its initial capital. As of December 31, 2025

and December 31, 2024, there were 24,572,600 Units and no Units outstanding, respectively.

The following tables present transactions in the Units during the year ended December 31, 2025:

Unless specific to a class, income and expenses are allocated proportionate to the class’s share of the Net Asset Value.

For the year ended December 31, 2025, the net investment income also includes a reallocation of Partnership expenses from the

General Partner.

Distributions to Unitholders

Distributions to Unitholders are recognized on the ex-distribution date of the distribution determined by the General

Partner. All distributions will be declared at the discretion of the General Partner. Unless otherwise determined by the General

Partner, all distributions of cash shall be made to the Unitholders in amounts proportionate to the aggregate net asset value of

the Units held by the respective Unitholders on the ex-distribution date set by the General Partner, except that the amount

distributed per Unit of any class may differ from the amount per Unit of another class on account of differences in class-specific

expense allocations or for other reasons as determined by the General Partner in good faith.

The following table presents our distributions that were paid and/or payable for each Class of its Units for the year ended

December 31, 2025:

Class of Units	Net Distribution per Unit
Class A-1a	$0.4003
Class A-1b	$0.4261
Class A-1c	$0.4600
Class F-1	$0.4600
Class I-1	$0.4600
Class X	$0.4600

The Partnership has adopted a distribution reinvestment plan (“DRIP”) pursuant to which Unitholders will have their

cash distributions automatically reinvested in additional Units of the Partnership’s same class of Units to which the distribution

relates unless they elect to receive their distributions in cash. Distributions that are reinvested are recognized in net assets on the

first business day following the record date of a distribution
