Also (from FED):

7.5.7 SITUATION C:

Team B has scored a field goal and A1 has the ball along the end line for a throw-in. Team A is not in the bonus. Prior to the ball being thrown inbounds by A1: (a) B1 fouls A2 inbounds near A1; (b) B1 fouls A2 at the *division line; (c) B1 fouls A2 beyond the division line; or (d) A2 requests a time-out.

RULING: In (a) and (d), Team A may throw-in from anywhere out of bounds along the end line following the foul reporting and the time-out. In (b) and (c), the ball will be given to Team A for a throw-in from the spot out of bounds nearest to where the foul occurred.

So from the OP I'm putting the ball in play nearest the spot of the foul after A1's second free throw. In a case where the foul was along the lane line (meaning end line throw-in) then if A1's 2nd free throw is successful then I would allow Team B to run the end line.

I have no clear cut rules backing. Just a mish-mash of other rulings.
