PRIVACY ACT NOTICE. -- Section 6109 requires recipients of dividend, interest,
or other payments to give taxpayer identification numbers to payers who must
report the payments to IRS. IRS uses the numbers for identification purposes.
Payers must be given the numbers whether or not recipients are required to file
tax returns. Beginning January 1, 1993, payers must generally withhold a portion
of taxable interest, dividend, and certain other payments to a payee who does
not furnish a taxpayer identification number to a payer. Certain penalties may
also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS. -- If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty

                                        3


of 5% on any portion of an under-payment attributable to that failure unless
there is clear and convincing evidence to the contrary.

(3) CRIMINAL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If
you make a false statement with no reasonable basis which results in no
imposition of backup withholding, you are subject to penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Falsifying certificates or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
