I will not sign your non-compete NDA. They are two separate things. An NDA is required to protect info from disclosure, even if we never use it (i.e. work together). A non-compete means our areas of business are too close and perhaps we should not be exchanging confidential information in the first place. However, an NDA with language that states you will not use confidential info except for the benefit of the person you received it from is perfectly reasonable.
