A vector-dominance two-photon exchange model is proposed to explain the recently observed production of {rho}{sup 0}{rho}{sup 0} and {rho}{sup 0}{phi} pairs in e{sup +}e{sup -} annihilation at 10.58 GeV with the BaBar detector. All the observed features of the data--angular and decay distributions, rates--are in agreement with the model. Predictions are made for yet-unobserved final states
