In case of late payment, Ebo Systems may suspend all orders in progress without any prejudice to any other means of action. Any sum not paid at the scheduled payment time will give rise by full right and without any prior warning, to payment of late payment interest at a rate equal to one and a half times the legal interest rate in force in France, from the due date up to the payment date. In case of failure to pay forty-eight hours after formal notice without response, the sale shall be cancelled by full right if considered necessary by Ebo Systems, who can request restitution of products, without prejudice for other compensation. The resolution will not simply affect the order involved but also all previous orders whether delivered or being delivered and related payment, whether due or not. In case of payment by letter of credit, the returned letter shall be considered as a refusal to accept, assimilated to a failure to pay. Non-payment of a single invoice or at a payment date will result in the immediate payment of all sums due without other warnings. In all preceding cases, the sums due for other reasons or any other cause become immediately payable if Ebo Systems does not opt for the resolution of the corresponding orders. The purchaser shall reimburse, other than the principle and the interest, all expenses caused by the recovery by litigation of sums due, as well as a 15% (fifteen percent) penalty of the unpaid sum. In no case may payments be suspended or be the subject of any compensation without prior written approval from Ebo Systems. All partial payments shall first used to pay compensation and penalties, then the sums with the oldest due payment date. No failure to pay, or late payment, can be justified later by a claim. Lastly, reference to the stipulations made in Article 2 of these general sales conditions is made.
