Yes there are ways. The best way at the moment (ie. until one of the WIP export plugins is done) is using Ultimate Unwrap. You'll have to purchase Ultimate Unwrap but the minor cost is worth it for all the features you get (including very robust b3d file format support; as far as I am aware Ultimate Unwrap is the only way to import and save out animated b3d files to some other file format.) UUnwrap comes with a 3D Studio Max exporter; export to UUnwrap and then save to b3d file format.
Other ways include exporting to Half-Life smd and using Milkshape to convert to b3d, or exporting to .x and using Ultimate Unwrap to convert to b3d.
And of course you could export directly to md2 file format from 3D Studio Max. Md2 has a lot of disadvantages over b3d however.
