English to Persian (Farsi) Law/Patents Law: Contract(s) Terms and conditions of a sale contract

Seller has the right to claim a higher indemnity from the Buyer for all external or additional costs and expenses reasonably incurred in the enforcement of its rights under this clause, including, but not limited to, the payment of agency and legal fees and expenses whether incurred before or after legal proceedings. Late payment interest on this indemnity will accrue, as form the date the expenditure is incurred. Moreover, In the event of late payment of any installment or balance, we reserve the right to consider the contract as dissolved, by right and without prior notice, either in full or in relation to the part which has not yet been executed. In case of late payment of an invoice, all other debts of the customer that are not yet due will become payable immediately by operation of law and without prior notification.
