(2) Definition. As used herein, the following term shall have the following meaning unless the context otherwise requires:

Class T Common Stock Conversion Rate. A fraction, the numerator of which is the Net Asset Value per share of Class T Common Stock and the denominator of which is the Net Asset Value per share of Class I Common Stock.

(4) Rights Upon Conversion. Each Share of Class T Common Stock shall automatically and without any action on the part of the holder thereof convert into a number of Shares (including fractional Shares) of Class I Common Stock equal to the Class T Common Stock Conversion Rate at the end of the month in which the dealer manager for a public offering of the Company, in conjunction with the transfer agent for such public offering of the Company, determines that the total selling commissions, dealer manager fees, and distribution fees paid with respect to all Shares of Common Stock held by a Stockholder in their account would exceed, in the aggregate, 9.0% (or a lower limit as set forth in an applicable agreement between the dealer manager of such public offering and a participating broker-dealer) of the gross proceeds from the sale of such Shares of Common Stock (including the gross proceeds of any Shares issued under a distribution reinvestment plan with respect thereto).
