(1) Around February 1, 2013, prior to the end of February 2013, the notice of the instant agreement was made by the Defendant Research Institute, and (2) as a large research institute with considerable organization, it was well aware that the Defendants did not constitute a public research institute under Article 2 subparag. 5 of the Special Act on the Promotion of Special Research and Development Zones, which is qualified to participate in the instant project. Nevertheless, the Defendant Research Institute, together with the Defendant Company, filed an application for support for the instant project with the Defendant Company, and concluded the instant agreement with the opportunity that the Plaintiff would not become a member of the Defendant Research Institute. Accordingly, the instant agreement was concluded by the Plaintiff due to gross negligence, but the Defendants were aware of the Plaintiff’s mistake and concluded by using it, so the Plaintiff’s expression of intent cannot be deemed to have been cancelled due to gross negligence, and thus, the Plaintiff’s expression of intent is not aware of the other party’s expression of intent.
