Raycast exit point of collider

Hi, I'd like to find the exit point of a raycast when hitting a collider, in the picture the raycast (the red line coming from left to right) you can see entering the collider on the top left and exiting the bottom right. What I'd like is the point of exit, is it possible as I cannot find the answer here or on google .. Thanks. ![alt text][1] [1]: /storage/temp/73681-screen-shot-2016-07-08-at-162124.jpg
