Class A1 Shares, which we 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. The Management Company currently expects that the Hydrogen Fund will attract aggregate capital commitments equal to its hard cap of euro 1.8 billion.

Investors cannot request the redemption of their shares by the Hydrogen Fund at any time prior to the final liquidation of the fund.
