has been received by Seller ; (ii) the full amount of the Security Withholding under Article 5 has been paid into the client escrow at Tiefenbacher within the time required under such Article; and (iii) the Buyers have complied with
their obligations under Article 8.2 to provide documents necessary (Abtretungsanzeige) to the Seller to enable it to avoid cash payment of VAT due by claiming Buyer(s)’s reimbursement. If the condition in Article 21.3 (iii) has not

under Article 8.2. 
 21.5 Notwithstanding the delivery of a Bank Guaranty, a Buyer shall make no demand for payment under such Guarantees for any claim
until: 
 (i) it has provided 30 day written notice of the claim to Seller on which the Buyer intends to make a demand, except where the
Guarantees or any of them have less than 30 days remaining in which case the notice shall be equal to the remaining period of the Guaranty; and 
 (ii) the Buyer has given Seller an adequate opportunity and details of the claim within that same period to reach agreement with the Buyer on such claims.

shall pay the arbitrator’s fees and cost, with each side bearing its own costs for these specific claims provided that if the Buyer does not justify its claim it shall return the amount of the funds drawn down to the Seller immediately with
interest at the European Central Bank Rate plus 8 per cent on the amount from the date of the drawn down on the Bank Guaranty.

fail to pay in the Security Withholding as required by Article 5.1. (iii) for 10 additional working days beyond the original due date the Seller may either withdraw both Bank Guarantees, or may declare as fully vested the Seller’s Loan in
the amount of 1,300,000 EUR (one million three hundred thousand EUR), which amount shall become immediately repayable to the Seller from that extended date with interest at the Loan rate from the original due date for such payment. Further, if as a
result of the Buyers’ failure to meet their obligations under Article 8.2, the Seller must pay VAT due in cash, and the defects in performance are not cured to allow Seller to reclaim the VAT payment in full, then the Seller may also declare
the Loan vested in the amount due with interest. 
 Furthermore, the failure of a claiming Buyer to repay to the Seller within 5 days an award in its favour
under the provisions of this Article shall also result at Seller’s option in a reduction of any remaining Guaranty in the same amount or a vesting of the amount due in the same manner from the Seller’s Loan.
