After 5 years the arms embargo is lifted, and after 8 years a missile embargo is lifted. I'm really surprised Obama and the Western powers agreed to that. Obama won't see much support for this deal in Congress.
This is my main concern as well. This is way too soon I think. Guess Putin and Lavrov pressed pretty hard for this to come through, cause they desperately need the money they can obtain from weapon sales (especially now that Russia is in a deep crisis). Should have been at least a 10-12 year embargo.
