 Given 2-morphisms $f$ and $g$, we define the horizontal composition $f *_h g$ to be any of the four
 equal 2-morphisms in Figure \ref{fzo5}.
-Figure \ref{fig:horizontal-compositions-equal}illustrates part of the proof that these four 2-morphisms are equal.

 Similar arguments show that horizontal composition is associative.

 Note that here we have used in an essential way the associativity of product morphisms (Axiom \ref{axiom:product}.3) 
 as well as compatibility of product morphisms with fiber-preserving maps (Axiom \ref{axiom:product}.1).
