Vector meson production is studied in the reaction γγ→K+K-π+π-. A clear Φ(1020) signal is seen in the K+K- mass distribution and a K*0 (890) signal is visible in the K±π one. Both do not seem to be strongly correlated with quasi two body final states. Cross sections for the processes γγ→K+K-π+π-, γγ→Φπ+π-, γγ→K+0K±π and upper limits for the production of Φp, ΦΦ and K*0 {Mathematical expression} are given as function of the invariant γγ mass.
