4. If, by virtue of a declaration under this article, this Convention does not extend to all territorial units of a State and the law governing the original contract is the law in force in a territorial unit to which this Convention does not extend, the law governing the original contract is considered not to be the law of a Contracting State.
4. 由于按本条规定作出的一项声明，本公约并非对一国所有领土单位皆适用的，而管辖原始合同的法律是本公约不适用的领土单位的现行有效法律，管辖原始合同的法律被视为并非一缔约国的法律。
