It is important that the description for the type of information is specific to what is being confidentially disclosed. As an example a software company working in the field of transportation systems might say; "The information being disclosed is a concept for passing waybills from carrier to carrier using mobile phone technology". This is by far preferential to saying "The information being to disclosed is information relating to software for transportation carriers". Anyone charged with determining whether confidential information is being disclosed is more able to make the assessment when the description is more specific.
In deed, to this writer's knowledge, crude buyers, particularly the more established and prominent ones, would very rarely offer an LOI upfront to any sellers to initiate a purchase. And when, especially, the supposed "seller" that's involved is one that is a virtual unknown to the buyer, or one that is merely an Internet_generated seller about whose bona fides and credentials the buyer knows practically next to nothing, one can be almost absolutely certain that the chances of a crude buyer of substance signing over an LOI to such a seller, is practically next to zero.
