the definition of Event of Default to include the announcement in connection
with any restatement or re-audit of the financial statements for the seven year

that period that reflects a reduction from the previously reported aggregate net
income for the period by an amount that is greater than 130% of the expected
aggregate reduction of net income for the period as disclosed in writing to
Wells Fargo prior to the Closing Date (as defined); (d) provide Wells Fargo with
the right to create a security interest in, or pledge all or any portion of its
rights and interest under the Loan Agreement to an Eligible Transferee (as
defined); (e) waive the EBITDA Default that occurred for the period ended June
30, 2005; and (f) extend the deadline to deliver certain audited consolidated
