Manning 3rdQ TD pass ML (+130)
Manning 4thQ TD pass ML (-115)
The only way you lose is if Manning doesn't throw a second half touchdown. If throws one in the 3rd qtr but not the 4th your $100 gets you $15. If he throws one in the 4th but not the 3rd, you push.
BUT, if he throws one in both qtrs....BOOM!
