The decay of {sup 10}C excited states to the 2p+2{alpha} exit channel has been studied using an E/A=10.7 MeV {sup 10}C beam inelastically scattered from a {sup 9}Be target. Levels associated with two-proton decay to the ground state of {sup 8}Be have been observed. These include states at 5.18 and 6.54 MeV which decay by sequential two-proton emission through the long-lived ground state of {sup 9}B. In addition, states at 5.3 and 6.57 MeV were found in which there is no long-lived intermediate state between the two proton emissions. For the 6.57 MeV state, the two protons are preferably emitted on the same side of the decaying {sup 10}C fragment.
