“(a) Treasury Function. The Company acknowledges that the Depository shall have the sole and exclusive right to determine the manner in which the proceeds of the Purchase Price is held (e.g. in Bitcoin, fiat currency or otherwise) and to make all investment decisions regarding the Note, the proceeds of the Purchase Price and proceeds of any investment made, including whether to lend it to third parties or invest in other assets or in securities. The Company further acknowledges that the Depository, its affiliates and its subsidiaries shall not have any fiduciary duty or other responsibility to invest the proceeds of the Purchase Price or proceeds of any investment in cash or cash equivalents and may, in its sole and absolute discretion, invest in liquid and/or illiquid investments including in or through related parties of the Depository. Notwithstanding anything to the contrary herein, the Depository shall invest or direct the investment of such funds as provided above, but only to the extent that such investment would not cause either the Company or the Guarantor to be considered an “investment company” under Section 3(a) of the Investment Company Act of 1940, pursuant to then applicable interpretations of the SEC.
