各位帮看看这两句意思的区别，涉及保密协议的条款，不太懂，请帮忙解释下两个句子的不同，非常感谢。
"However, under no circumstances shall the treatment of the confidential information be held under a reasonable degree of care."
"However, under no circumstances shall the treatment of the confidential information be held under less than a reasonable degree of care."
