The one-loop and two-loop contributions to kählerian effective potential and two-loop (first non-zero) contribution to chiral effective potential are found for arbitrary form of functions $K(\barΦ,Φ)$ and $W(Φ)$. It is found that despite the theory is non-renormalizable in general case two-loop contribution to holomorphic effective potential is always finite.LaTeX, 7 pages; to be published in Proceedings of International Workshop "Supersymmetries and Quantum Symmetries - 1999", Dubna, Russia; minor correctionsHigh Energy Physics - Theorytext
