The table below indicates the calculations related to the payments to the Bank for indicative forecasted next two milestone payments of USD 50m (in accordance with Articles 3.3(a) and 3.3(b)) and the USD [***] (in accordance with Article 3.3(c)) related to the US Regulatory Approval. The table below, based on the assumed exchange rate, shows that with USD [***], the cumulative milestone in EUR terms amounts to EUR [***], and thus the [***] rate has been used. Should the exchange rate have been different, and the cumulative milestone exceeded EUR [***], the [***] rate would have applied. The same mechanics outlined for the USD [***]milestone would apply to any other milestone achieved earlier, except for the one mentioned in Article 3.3(c) related to US Regulatory Approval.
