Epicor Software Corporation (the "Company") is filing this Amendment on Form
10-K/A to correct two points, one in Part I, Item 8, Financial Statements and
Supplementary Data regarding Note 1 to the Consolidated Financial Statements and
one in Part IV, Item 14, Exhibits, Financial Statement Schedules and Reports on
Form 8-K.

In Note 1 to the Company's Consolidated Financial Statements, under the heading
"Net Income (Loss) per Share" there was a typographical error for the line items
"Net Income (loss) per share - basic" and "Net Income (loss) per share -
diluted" for the year ended June 30, 1998. The Net Income (loss) per share -
basic was reported as ($.56) and the Net Income (loss) per share - diluted was
reported as ($.45) when such numbers should have been $.56 and $.45,
respectively. Set forth below is a corrected table for Net Income (Loss) Per
Share:

                                     PART I

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The section entitled "Net Income (Loss) per Share" in Note 1 to the Consolidated
Financial Statements is hereby amended to read as follows:

"NET INCOME (LOSS) PER SHARE

Basic net income per share is computed by dividing net income (loss) by the
weighted average number of shares of common stock outstanding during the period.
Diluted net income (loss) per share is computed by dividing net income (loss) by
the weighted average number of shares of common stock and common stock
equivalents outstanding during the period. For the year ended December 31, 1999,
the six months ended December 31, 1998 and the year ended June 30, 1997,
employee stock options and preferred stock were not considered in calculating
diluted net loss per common share as their effect would be anti-dilutive. As a
result, during those periods the Company's basic and diluted net loss per common
share are the same.

The following table computes basic and diluted net income (loss) per share (in
thousands, except per share amounts):
