(1) If the donor fraudulently conceals a defect in the donated thing, they are obliged to compensate the donee for the resulting damage.
(2) If the donor promised to provide a thing designated only by class that the donor was still to acquire, the donee may, if the thing provided is defective and the donor was aware of the defect when the thing was acquired or remained unaware of it due to gross negligence, demand that in place of the defective thing a thing free of defects is supplied. If the donor fraudulently concealed the defect, the donee may demand damages for non-performance in place of supply of a thing free of defects. The provisions applicable to a warranty for defects in a thing sold apply to these claims accordingly.
