Section 2--317. Cumulation   and   Conflict  of  Warranties  Express  or
                    Implied.
    Warranties whether express or implied shall be construed as consistent
  with  each  other  and  as  cumulative,  but  if  such  construction  is
  unreasonable the intention of the parties shall determine which warranty
  is dominant. In ascertaining that intention the following rules apply:
    (a)  Exact or technical specifications displace an inconsistent sample
  or model or general language of description.
    (b) A sample from an  existing  bulk  displaces  inconsistent  general
  language of description.
    (c)  Express warranties displace inconsistent implied warranties other
  than an implied warranty of fitness for a particular purpose.
