  A new class of models of dynamical supersymmetry breaking is proposed. The
models are based on SU(N_C) gauge theories with N_F(<N_C) flavors of quarks and
singlets. Dynamically generated superpotential exibits runaway behavior. By
embedding the models into conformal field theories at high energies, the
runaway potential is stabilized by strong quantum corrections to the Kahler
potential. The quantum corrections are large but nevertheless can be controlled
due to superconformal symmetry of the theories.
