The converted policy shall not exclude a preexisting condition not excluded by the group policy. However, the converted policy may provide that any hospital, surgical or medical benefits payable thereunder may be reduced by the amount of any such benefits payable under the group policy after the termination of the individual's insurance thereunder. The converted policy may also include provisions so that during the first policy year the benefits payable under the converted policy, together with the benefits payable under the group policy, shall not exceed those that would have been payable had the individual's insurance under the group policy remained in force and effect.
