As previously announced on April 5, 2021, we were admitted as an anchor investor in the Clean H2 Infra Fund (f/k/a the FiveT Hydrogen Fund), which is a private equity fund whose main objective is to support the hydrogen market by investing globally, directly or indirectly, in infrastructure projects or companies active in the hydrogen sector (the “Hydrogen Fund”).

As discussed in the “Equity Method Investments” section above, our investment to date is euro 2.2 million, making our unfunded commitment euro 47.8 million.

The fund manager of the Hydrogen Fund (the “Management Company”) will establish a Limited Partners Advisory Committee (the “LPAC”) as from the first closing date (which has yet to occur but shall be no later than June 30, 2022) to consult with and help advise the Management Company with respect to certain key decisions governing the fund that the Management Company shall make. The LPAC is expected to be comprised by up to fifteen (15) members, the majority of whom shall be chosen by certain industrial investors and who shall be (i) representatives of the anchor investors and (ii) subject to any remaining available seats, representatives of the non-anchor investors selected by the Management Company.

Class A1 Shares, which we shall hold, are entitled to the return of any associated paid-up capital contributions (excluding any subscription premium or default interest, if any), the Preferred Return calculated thereon as described below, and their share of the Hydrogen Fund’s capital gain beyond the Preferred Return in accordance with the order of distributions in the by-laws of the Hydrogen Fund (in each case to the extent of available funds). The “Preferred Return” equals an annual interest rate of seven percent (7%) if fifteen percent (15%) of the Hydrogen Fund’s aggregate capital commitments from all investors is

invested in strategic investments; provided, however, that such seven percent (7%) interest rate shall be reduced in a linear fashion to six and one-half percent (6.5%) if twenty percent (20%) of the Hydrogen Fund’s aggregate capital commitments from all investors is invested in strategic investments.
