Since nobody takes this thread seriously, lemme give this another shot:
How are you trying to escape the position?
First of all, you need to push his elbow and start freeing the leg (starting with the knee if he is hugging the thigh) that he is controlling with his arms, then scoot your ass down to the mat. If your hips are on top of his, then he is controlling you. Now you can use your free leg to remove the lockdown, and you are in a back control defense scenario, defending against a single hook. If you want to be real smooth, you can then invert, grab his knee and hip, switch your knee position on his hooking leg and put him in the 'truck' instead. (See Ryan Hall's rolling back take DVD.)
Now, obviously, this is not going to be easy, because just as you're trying to undo everything he has done, he can re-do it as you try to escape. This is just how it is, as it happens to be a very dominant position. It is after all a form of back control.
