                                  ATTACHMENT A

         N-Viro International Corporation (the "Company") expects to report on
Form 10-K, when filed, that consolidated revenues amounted to approximately $4.2
million for the year ended December 31, 1996, compared to $5.2 million for the
year ended December 31, 1995.

         The Company anticipates generating a net loss of $193,000 for the year
ended December 31, 1996 compared to a combined net loss of $1.8 million for the
year ended December 31, 1995. The decrease in net loss was principally due to:
reduced expenditures for salaries, employee benefits and professional fees, as
well as the discontinuation of losses generated by two subsidiaries that were
sold in 1995 and early 1996.

         The Company expects working capital to be approximately ($286,000) as
of December 31, 1996, compared to ($34,000) as of December 31, 1995. The
decrease in working capital was principally due to the operating loss and the
reclassification of long-term debt as current liabilities as a result of the
passage of time.

         The Company expects stockholders' equity to amount to $1.4 million as
of December 31, 1996, compared to $1.6 million as of December 31, 1995. The
decrease in stockholders' equity was principally due to the operating loss.
