A recurring problem, this ARC business... OK, once again: ARC/INFO 
produces *two* kinds of export formats, apart from its generic binary 
format. If you're having the *binary* stuff (easily recognizable by the 
fact that the map (coverage) is a directory in which you will find files 
with names likes arc, aat, pat, lab, tic and a lot more), then there is 
no way using the data outside ARC/INFO. If you're having the 'normal' ascii 
export format (extension .e00, .e01 etc.) you're also in trouble as this 
is only meant for conversion between different platforms that run 
ARC/INFO. The .e00 format is about as complex as DXF and is to my 
knowledge not supported outside ARC/INFO. The third format is UNGENERATE, 
a simple ascii format that is compatible with many other GIS packages. My 
experience is that most ARC/INFO users don't know these simple facts, so 
I end up regularly with diskettes from people with binary ARC/INFO or 
.e00 formats, and I'm afraid the same has happened to you. Hope this 
helps you!
