We present a UBV CCD photometric study of four open clusters, NGC 7245, King 9, IC 166 and King 13, located between l = 90° and 135°. All are embedded in a rich Galactic field. NGC 7245 and King 9 are close together in the sky and have similar reddenings. The distances and ages are: NGC 7245, 3.8±0.35 kpc and 400 Myr; King 9 (the most distant cluster in this quadrant), 7.9±1.1 kpc and 3.0 Gyr. King 13 is 3.1±0.3 kpc distant and 300 Myr old. King 9 and IC 166 (4.8±0.5 kpc distant and 1 Gyr old) may be metal-poor clusters (Z = 0.008), as estimated from isochrone fitting. The average value of the distance of young clusters from the Galactic plane in the above longitude range and beyond 2 kpc (-47±16 pc, for 64 clusters) indicates that the young disc bends towards the southern latitudes.
