Narrative:

While on climb out from ama at approximately 5000 ft MSL, we received a TCASII alert and had to take evasive action to avoid another aircraft. When I looked in the direction of the alert, I could see that we were on a head-on collision with another aircraft. I leveled a little above 5000 ft and altered course to the right. The other aircraft which appeared to be a beech baron or some other light twin also saw us and altered his course to the right, right after the tower had given us the TA. We were both in tower controled airspace and the tower controller apologized for the late advisory. Our flight then proceeded to las without further incident.
