We report the first observation of the exclusive decays [Formula presented], using [Formula presented] [Formula presented] pairs collected at the [Formula presented] with the CLEO detector. We measure the following branching fractions: [Formula presented], [Formula presented], [Formula presented], and [Formula presented]. The [Formula presented] branching ratios are the averages of those corresponding to the 00 and 11 helicity states. The errors shown are statistical and systematic, respectively.
