Sadly, the 24-105L is not the greatest choice for low light photography unless you have a tripod. This is something that I realized as soon as i bought my 24-105 and took it to a graduation that wasn't well lit.
That aside, doing F4 @ 1/10 is a bit slow, so you'll unless you're really steady, you'll get a little blur. was there anything around that you could have used to steady your camera while taking the shot?
a few other suggestions:
1. jumping up to ISO800
2. shoot in raw, underexpose a stop or 2 to get a faster shutter speed, and get the exposure back in PP.
3. tripod / mirror lockup / shutter release remote
4. save up for a good lens you can use in low light situations, like a 24-70L F2.8 or even a nifty-fifty (since the 24-70 is not a cheap lens)
just keep in mind that you can adjust the exposure, levels, etc., but you can't save a blurred shot. I like the first 3 shots, but i wish they were a bit sharper and a little brighter.
