Kwaliteitsrekening (USD account), from or on behalf of the Purchaser the amount of USD [•], being the (i) Share Consideration Amount plus

2.2. Upon receipt of the Completion Amount in the Notary Account, I will confirm in writing receipt thereof to each of the Purchaser and the Seller (the “First Confirmation”), such First Confirmation to be made by email addressed to the Purchaser and the Seller at the addresses and for the attention of the persons mentioned in the address line of this letter above.

2.3. Upon receipt of the Completion Amount into the Notary Account, I will hold the Completion Amount for the account of the Purchaser as the person who made the payment or on whose behalf the payment was made and until I will hold the Completion Amount for the account of the Seller as the person who becomes entitled thereto (or to part thereof) in accordance with this letter.

2.4. Immediately upon receipt by me of each of:

a. the Completion Amount in the Notary Account; and

b. a notice in the form as attached as Annex 1 to this letter, from the Purchaser and the Seller confirming that the steps referred to under 1 (a) and (b) and 2 (a) of Schedule 4 of the Share Purchase Agreement have been satisfied (the “Notice”),

I will execute the Transfer Deed.
