Abstract: Let $ \mathfrak{N}$ be a variety of groups which has nilpotency class two and finite odd exponent. Let $ \mathfrak{A}$ be an abelian variety of groups with finite exponent relatively prime to the exponent of $ \mathfrak{N}$. The existence in the product variety $ \mathfrak{N}\mathfrak{A}$ of nonnilpotent critical groups having central monoliths is established. The structure of these critical groups is studied. This structure is shown to depend on an invariant, k. The join-irreducible subvariety of $ \mathfrak{N}\mathfrak{A}$ generated by the nonnilpotent critical groups of $ \mathfrak{N}\mathfrak{A}$ having central monoliths is determined, in particular, for k odd.
