I wrote an e-mail to AGFA back in the spring describing these types of storage conditions. AGFA wrote back saying these conditions are perefectly fine for their b&w films - refrigeration\freezing aren't necessary. They didn't say exactly how long film starts to degrade if not frozein, but the implication was clear that a few years out of date would be perfectly reasonable. Go ahead and use the film without worry. I'd feel the same about the paper.
