Non-disclosure Agreements (NDAs) are sometimes referred to as confidentiality agreements and are used when NETL and/or another party wish to exchange information that is either considered potentially patentable by NETL or proprietary by the other party. NETL is bound to maintain information received in the course of business confidential by the Trade Secrets Act (18 USC Sec. 1905). However, NETL will enter into an NDA that reiterates this protection. NDA's may be unilateral or bi-lateral, depending on the circumstances. NETL only executes its own NDA's.
