  We consider solitonic solutions of coupled scalar systems, whose Lagrangian
has a potential term (quasi-supersymmetric potential) consisting of the square
of derivative of a superpotential. The most important feature of such a theory
is that among soliton masses there holds a Ritz-like combination rule (e.g.
$M_{12}+M_{23}=M_{13}$), instead of the inequality ($M_{12}+M_{23}<M_{13}$)
which is a stability relation generally seen in N=2 supersymmetric theory. The
promotion from N=1 to N=2 theory is considered.
