(4) A place or method of inspection fixed by the parties is presumed to
be exclusive but unless otherwise expressly agreed it does not postpone
identification or shift the place for delivery or for passing the risk of
loss. If compliance becomes impossible, inspection shall be as provided in
this Section unless the place or method fixed was clearly intended as an
indispensable condition failure of which avoids the contract.
