CONFIDENTIALITY OBLIGATION. The Receiving Party agrees to protect the Confidential Information by using the same degree of care, but not less than a reasonable degree of care, to prevent the unauthorized use, dissemination or publication of the Confidential Information as the Receiving Party uses to protect its own confidential or proprietary Information of a like nature.
