We extend our previous work on the nonlinear realization of the top quark field, which is a consequence of its being much heavier than any other scales. A one-loop effective Lagrangian to account for virtual top effects is constructed in this article for processes where there are two external fermions, as well as any number of bosons. In particular, we focus on those terms which have a power dependence on the top mass mt.
