It is demonstrated that {ital N}({pi},{ital e}{sup +}{ital e}{sup {minus}}){ital N} measurements will provide new information about the nucleon timelike form factor in the {phi} meson region including the value of the {phi}{ital N} coupling {ital g}{sub {phi}{ital NN}}. Using vector meson dominance, {ital N}({pi},{ital e}{sup +}{ital e}{sup {minus}}){ital 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}{ital 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. {copyright} {ital 1996 The American Physical Society.}
