We consider the non-selfadjoint operator H = [ -δ + μ - V 1-V2 V2 δ - μ + V1 ] where μ < 0 and V1, V2 are real-valued decaying potentials. Such operators arise when linearizing a focusing NLS equation around a standing wave. Under natural spectral assumptions we obtain L 1(R2)×L1(R2) →; L (R2)→;L(R2) dispersive decay estimates for the evolution e<HPac. We also obtain the following weighted estimate ||w-1e ithPacf||L(R2)<L 1(R2) . 1 |t| log2(|t|) |wf|L 1(R2)×L1(R2), |t| > 2; with w(x) = log2(2 + |x|).
