Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, 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. IF YOU ARE A NONRESIDENT ALIEN OR A FOREIGN
ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH A PAYER AN APPROPRIATE
COMPLETED INTERNAL REVENUE FORM W-8.
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),
6045 and 6050A of the Code and the regulations promulgated thereunder.
Privacy Act Notice.--Section 6109 of the Code requires most recipients of
dividend, 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. Beginning January 1, 1984, payers
must generally withhold 31% 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) Civil 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 a penalty of $500.
(3) Criminal Penalty for Falsifying Information.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
(4) Misuse of Taxpayer Identification Number (TINs).--If the requestor
discloses or uses TINs in violation of Federal law, the requestor may be
subject to civil and criminal penalties.

SERVICE.
