We present a conditionally integrable level-crossing model for the quantum time-dependent two-state problem involving irreversible losses from the second level. The model is given by an exponentially varying Rabi frequency and a level-crossing detuning that starts from the exact resonance and exponentially diverges at the infinity. The model includes irreversible losses from the second level, while the spontaneous relaxation to the first level is neglected. We derive the exact solution of the two-level problem for this and discuss the dynamics of levels' populations under different regimes of the interaction.
