Question

非常急！！！那位英语高手帮我翻译一下下面合同抬头？ 用在线翻译者最好不要提交答案 多谢合作！

The contract provides mutual agreements to close the deal and becomes fully valid if replaced with a hard contract duly signed and sealed by the Buyer and Seller. The contracts signed and sealed in electronic format have its full legal power and remain fully valid until Sides exchange duly signed and sealed hard copies of the hard contract.

Answer 1

双方经协商一致，达成此项交易；此项严格的合同一旦到期被签署，并由双方共同铅封后立即生效。直至双方互换到期的签署并铅封过的全套合同正本，以电子形式签署并铅封的合同具有同等的法律效力，并一直有效。
