End the motion by proposing a resolution that you think the AGM should take. Give alternative suggestions. If the first proposal is rejected, you may have an alternative that is almost as good, which the meeting may approve instead.
Think about what arguments the board may use to have the motion rejected. Prepare yourself by covering these arguments with your weighty counter-arguments already in the exercise.
Feel free to add in the motion that if there are any questions, you would like the board to contact you.
