Magnetotransport and drag measurements on a quasi-Corbino two-dimensional electron bilayer at a total filling factor of 1 (nu(T)=1) reveal a drag voltage that is equal in magnitude to the drive voltage as soon as the two layers begin to form the expected nu(T)=1 exciton condensate. The identity of both voltages remains present even at elevated temperatures of 0.25 K. The conductance of the drive layer vanishes only in the limit of strong coupling between the two layers and at T -> 0 K which suggests the presence of an excitonic circular current.
