I would think it'd be fine. My assumption is that many times expiration dates err on the side or being too early rather than too late, and in some cases are virtually irrelevant (e.g., meds must carry expiration dates, but some seem not to be too realistic, especially for dry pills, like acetaminophen -- I'm still taking tablets from a plastic bottle that has an expiration date of Oct 2005 -- they seem to work and I feel no ill effects, not surprisingly).
For products like milk, eggs, meat, etc., I tend to follow expiration dates, but for vacuum-sealed food items, like your caviar, I'm guessing it'd be okay...and it "expired" relatively recently.
The real test would be to taste it. If the caviar is mushy or, obviously, off-tasting, dump it -- my guess is that it will taste fine.
