16.5 If any payment by one party under an indemnity in this Agreement is subject to income tax or corporation tax (or any tax replacing them) in the hands of the recipient, the recipient may demand in writing to the party making the payment that the payment shall be increased by such amount (the "Additional Amount") as would ensure that, after taking into account any such tax payable in respect of the Additional Amount and any credit or saving that may arise as a result of paying the Additional Amount, the recipient receives and retains a net sum equal to the amount it would have otherwise received had the payment not been subject to such tax, with the result that it is left in no better or worse tax position. The party making the payment shall pay the Additional Amount within ten (10) Business Days of receipt of such demand.
