Technical foul administration at end of first quarter

[jodibuck]

NFHS game: A1 releases the ball on a shot before horn sounds to end the first quarter. The ball goes in the basket, then A1 taunts B1 clearly after the horn sounded. A technical foul is called on A1. When do we administer the technical foul? Do we shoot the foul shots, then go to alternating possession arrow to start the 2nd quarter, or do we administer the foul shots to start the second quarter, with A1 getting the ball at the division line as part of the technical foul. Rule 5-6-2 exception 3 says: No penalty or part of a penalty carries over from one quarter or extra period to the next. However, Rule 5-6-2 exception 4 says: If a technical foul occurs after the ball has become dead to end a quarter or extra period, the next quarter or extra period is started by administering the free throws.
