Scharlemann constructed a connected simplicial 2-complex $Gamma$ with an action by the group ${mathcal H_{2}}$ of isotopy classes of orientation preserving homeomorphisms of $S^3$ that preserve the isotopy class of an unknotted genus 2 handlebody $V$. In this paper we prove that the 2-complex $Gamma$ is contractible. Therefore we get a finite presentation of ${mathcal H_{2}}$.
