(2) Is attempting to commit, committing, or fleeing after the commission or attempted commission of a felony; or
 

(3) Was the aggressor or was engaged in a combat by agreement unless he withdraws from the encounter and effectively communicates to such other person his intent to do so and the other, notwithstanding, continues or threatens to continue the use of unlawful force.
