Dear Terry:
This will confirm our conversations regarding the Common Stock of
N-Viro held by Hydropress and acquired pursuant to our agreement of December 30,
1994, as amended by our Settlement Agreement effective as of March 22, 1999 (as
so amended the "Agreement").
1. You will instruct your transfer agent that all stock held by
Hydropress is no longer subject to any restrictions on transfer.
2. By signing below you waive the currently effective 18-month period
during which Hydropress was to defer any stock sales to permit the sales
described below.
3. Hydropress may seek to sell initially up to 15,000 shares of N-Viro
Common Stock monthly. Offers for sale in excess of the 15,000 shares shall in
each case require the prior approval of N-Viro given by fax signed by you.
4. As to any sales by Hydropress under this arrangement, N-Viro shall
be released from its minimum guarantee obligations as set forth in the
Agreement.
If the foregoing is acceptable, please sign below and return to my by
facsimile.
Very truly yours,
/s/ Dana G. Taylor
