We have studied transverse momentum distributions for exclusiveρ0 muoproduction on protons and heavier nuclei at $2\lt Q^2\lt 25$ GeV2. The $Q^2$ dependence of the slopes of the $p_t^2$ andt′ distributions is discussed. The influence of the non-exclusive background is investigated. Thept2-slope for exclusive events is 4.3±0.6±0.7 GeV$^{−2}$ at large $Q^2$. The $p_t^2$ spectra are much softer than inclusive $p_t^2$ spectra of leading hadrons produced in deep inelastic scattering
