Heat oven to 325°F. Line shallow roasting pan with foil. Place ham, cut side down, on rack in pan. Insert ovenproof meat thermometer so tip is in thickest part of ham and does not touch bone.
Bake uncovered about 1 hour 30 minutes or until thermometer reads 135°F to 140°F. Meanwhile, in small bowl, mix remaining ingredients. Brush over ham during last 30 minutes of baking.
Cover ham loosely with foil and let stand 10 to 15 minutes for easier carving.
