Resurrecting Rosemary

[Bumperstump Cummerbund]

I think I may have killed my rosemary plant. Everyone told me they were very drought hardy, so over winter, I pretty much didn't water it, or even look at it unless I needed rosemary. Click the pic to see what it looks like now :/

I've fed it, and have been watering every couple of days. Should I prune it right back to encourage new growth if I haven't completely killed it yet?

Any suggestions much appreciated!
