N2 - We consider compactifications of type II string theory using exact internal CFT's with central charge c = 9 + epsilon, vertical bar epsilon vertical bar 0 the potential is positive and the dilaton is ultimately driven to weak coupling. For epsilon <0 the dilaton is driven to strong coupling, but we can stabilise the background by including D-branes. The resulting minimum admits an AdS(4) solution where the cosmological constant is of the order epsilon(3) and the string coupling constant is of order epsilon. Furthermore these CFT's typically do not possess any massless or tachyonic modes. Thus these vacua provide exact CFT descriptions of moduli stabilisation in weakly coupled string theory.
