Section 515A.4-113 - EXCLUSION OR MODIFICATION OF IMPLIED WARRANTIES(a) Except as limited by subsection (b) implied warranties: (1) may be excluded or modified by agreement of the parties; and(2) are excluded by expression of disclaimer, such as "as is," "with all faults," or other language which in common understanding calls the buyer's attention to the exclusion of warranties.(b) With respect to a purchaser of a unit which may be occupied for residential use, no general disclaimer of implied warranties is effective, but a declarant may disclaim liability in an instrument signed by the purchaser for a specified defect or specified failure to comply with applicable law, if the defect or failure entered into and became a part of the basis of the bargain.1980 c 582 art 4 s 515.4-113
