such Lock-up Shares, whether any of these transactions are to be settled by delivery of any such Lock-up Shares, in cash or otherwise,
publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or
other arrangement, or engage in any Short Sales (as defined below) with respect to any security of AQU.



(b)In
furtherance of the foregoing, AQU will (i) place an irrevocable stop order on all AQU Shares which are Lock-up Shares, including
