Dear David:

As you know, I have resigned from Bion's Board, effective today.  I and
certain business colleagues are currently engaged in intensive negotiations to
acquire a business.  This matter is now consuming essentially all of my time.

I wish Bion every success in its continuing financing efforts and in
exploiting its promising technology.

Sincerely,


/s/ Howard E. Chase
