Owners of land shall not be liable for injuries, mental harm or death sustained by persons using their land, including but not limited to cave resources, for recreational, educational or scientific purposes. By granting permission for entry or use, the owner does not thereby:
     (a) extend any assurance that the premises are safe for such purposes, or
     (b) constitute to the permittee the legal status of an invitee or licensee to whom a duty of care is owed, or
     (c) assume responsibility for or incur liability for any injury to person or property caused by an act or omission of a permittee except as provided in this Section.
     This Act shall not limit the liability which otherwise exists for (1) willful or malicious failure to guard or warn against a dangerous condition, use or natural structure; or (2) failure to guard or warn against a dangerous manmade structure, fixture or activity; or (3) for injury suffered in any case where permission to enter for the above purpose was granted for a consideration.
     Nothing in this Section creates a duty of care or ground of liability for injury to person or property.
