Go to the Saints Row District and achieve a four star Ultor notoriety by causing as much damage as you can. Once you have accomplished this, head to the nearest Forgive and Forget to shake off the police, then head to the Ultor base. While Ultor is distracted, steal the keycard to open the doors for the labratories. Kill anyone who impedes your progress and plant the bombs in each labratory. Once finished, comendere the Bear and move as far away from the base before the bombs detonate.
