taxpayer identification number to payers, who must report the payments to the
IRS. The IRS uses the number for identification purposes and may also provide
this information to various government agencies for tax enforcement or
litigation purposes. Payers must be given the numbers whether or not recipients
are required to file tax returns. Payers must generally withhold up to 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) 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) 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, you are subject to a $500 penalty.

(3) Criminal Penalty for Falsifying Information -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
