Let A be a separable exact quasidiagonal C\*-algebra. Suppose that ?: A Γ L(H) is a faithful representation whose image does not contain nonzero compact operators. Then there exists a sequence . n : A Γ L(H) of completely positive contractions such that &?(a)&. n (a)& Γ 0 for all a # A, and the C\*-
