  We construct a simple local model of dynamical supersymmetry breaking. The
model is a one generation SU(5) that arises from a IIB Z_N orientifold. It does
not admit a runaway direction and is argued to stabilize the blowup mode
related to the corresponding U(1) factor. The theory demonstrates the existence
of a new class of "blowup" fractional branes. We further discuss a compact
realization of the quiver on a Calabi-Yau 3-fold which enables one to add
fluxes and stabilize the complex structure moduli.
