In this paper, we classify the finite generalized quadrangles of order ( s, t), s, t > 1, which have a line L of elation points, with the additional property that there is a line M not meeting L for which { L, M} is regular. This is a first fundamental step towards the classification of those generalized quadrangles having a line of elation points.
