  We evaluate the static $qqqq\bar{q}$ potential in the quenched theory at
$\beta=5.8$ and $\beta=6.0$ on a lattice of size $16^3\times 32$. The mass and
density-density correlator for the $\Theta^+$ is investigated in the quenched
theory at $\beta=6.0$ on lattices of size $16^3\times 32$, $24^3\times 32$ and
$32^3 \times 64$.
