HAVE ONE), WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO THE PAYER.
IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO SIGN AND
DATE THE FORM.
Certain payments other than interest, dividends, and patronage dividends that
are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under Sections 6041, 6041A(a),

PRIVACY ACT NOTICE. -- Section 6109 of the Code requires most recipients of
dividends, interest or other payments to give taxpayer identification numbers to
payers who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payers must be given the numbers whether or not
recipients are required to file tax returns. Payers must generally withhold 31%
of taxable interest, dividends 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 correct taxpayer identification number to a payer, you may
be subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you
make a false statement with no reasonable basis that results in no backup
withholding tax, you are subject to a penalty of $500.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

CONSULTANT OR THE INTERNAL REVENUE SERVICE.
