The processes $e^+e^-tomu^+mu^-$ and $e^+e^-topi^+pi^-$ have been studied with SND detector at VEPP-2M $e^+e^-$ collider in the vicinity of $phi(1020)$ resonance. The branching ratios $B(phitomu^+mu^-)=(3.30pm 0.45pm 0.32)times 10^{-4}$ and $B(phitopi^+pi^-)=(0.71pm 0.11pm 0.09)times 10^{-4}$ were obtained.
