Well it depends what you extracted it with. Basically what you extracted was the meta plus the halo style info for the model. I'm guessing HMT was used for this? You'll either need to use sparkedit or eschaton to export an actual model. Or I suppose you could try converting the .vertices and .indeces by hand to .obj (not recommended if you don't already know how, plus it'd take a long time for a bsp).
