The deal has been struck at close. If price continues to drop long term holders are better off, since they will end up getting more MITL. Exiting this position will be tricky on Monday. Two options exists, hold for retrace, which is likely to return to $12.20, maybe better; or sell at loss at $11.85 limit.
Pre-Market price action will determine whether or not to double up and hold out until the deal completes.
