Is This Yeast Too Old?

In my fridge, I've got a vial of White Labs San Fransisco Lager yeast with an expiration date of Dec. 30, 2008. With a proper starter and maybe some nutrients, do you think the yeast would be viable? Might it produce off flavors given its age?

If it's been treated well, it shouldn't be a big problem to nurture it back to health. Once you have the yeast population at its proper levels, the yeast will behave as good as new.

Thanks. I think it will end up in a California Common.
