It is demonstrated that N(pi, (e){sup +} (e){sup -})N measurements will provide new information about the nucleon timelike form factor in the phi N coupling g{sub (phi-NN)}. Using vector meson dominance, N(pi, (e){sup +} (e){sup -})N calculations reveal a 3 order of magnitude enhancement from the phi resonance coupled to the nucleon compared to the expected background phi production from the (rho)(pi)(phi) contribution through rho exchange. The effect from phi-N coupling in the nucleon form factors yields a novel experimental signature for OZI (Okubo-Zweig-Iizuka) violation and the related strangeness content of the nucleon.
