That is the definition.
But perhaps some here may want to know why have one.
For instance, KWG hires or arranges someone to do a study, or construct, the N/S railraod.
The hired company gets to see KWG's private information which cost the company a lot of dough..
To do that a non-disclosure agreement is necessary so that the hired company does not divulge this info to KWG's competitors or devalue the info through public knowldege.
That is for non disclosure.

Similarly with Standstill.

The hired company having examined the data is in a position to know details about the KWG and besides continuing the railway, they decide that KWG is a worthy company to buy.
Stand still is a preventive measure against a Hiring taking advantage of the disclosing company.

Hope that helps someone.
