one hyphen: i.e. 00-0000000. The table below will help determine the number to
give the payer.

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 sections 6041, 6041A(a), 6042, 6044, 6045,

PRIVACY ACT NOTICE. Section 6109 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 and to help verify the accuracy of tax reforms. Payers must be given
the numbers whether or not recipients are required to file tax returns. 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 correct 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) 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. Willfully falsifying
certifications or affirmations may subject you to criminal penalties, including
fines and/or imprisonment.

(4) Misuse of Taxpayer Identification Numbers. If the payer discloses or uses
taxpayer identification numbers in violation of Federal law, the payer may be
subject to civil and criminal penalties.

SERVICE.
