Ulster secured a bonus point as they scored four tries in an emphatic win over Irish interprovincial rivals Munster at a packed Ravenhill.
Playing against the wind Ulster led 20-10 at half-time and then pulled away.
Stefan Terblanche, John Afoa, Ian Humphreys and Ruan Pienaar were the Ulster try-scorers, with Luke O'Dea and Johne Murphy scoring Munster's tries.
Humphreys kicked eight points and Pienaar three for Ulster while Ian Keatley landed seven points.
Both sides began the game without their Irish international players, who are taking part in a training camp.
Ian Humphreys gave his side an early boost by kicking a penalty but Luke O'Dea crossed the line for the visitors in the 14th minute.
Keatley executed a perfect cross kick and young winger O'Dea brushed off the challenge of Adam D'Arcy to stretch and score in the corner.
Keatley converted but Humphreys soon knocked over his second penalty to reduce the deficit to one point.
Ulster's first try came on 25 minutes, Afoa winning the ball and Terblanche completing a fine move involving Humphreys and Darren Cave by diving over in the corner.
Humphreys added the additional two points to make it 13-7.
Keatley was successful with his first penalty attempt of the game but then missed with a simple effort from in front of the posts.
Afoa touched down in the 35th minute after Ulster recycled possession and Pienaar provided the pass for the big Kiwi prop to score.
Humphreys' conversion gave Ulster a 10-point lead at the interval.
Five minutes into the second half, Ulster scored their third try of the game.
A tackle by flanker Willie Faloon secured turnover ball, Pedrie Wannenburg kicked the ball on and Humphreys won the race to the line.
The Ulster fly-half was off-target with his relatively straightforward conversion attempt, which cannonned off the upright.
Pienaar sealed the bonus point by showing a fine turn of speed to sprint over the line after Ulster turned the ball over at a scrum, Humphreys again failing to convert.
The Springbok then kicked a penalty but Munster ran in for a late try.
Peter Nelson was unable to hold onto a Pienaar pass and Murphy was on hand to capitalise by touching down, Keatley adding the conversion.
Munster lie third in the table, with Ulster moving up one place to seventh.
