000-00-0000.  Employer identification numbers have nine digits separated by only
one hyphen: i.e.  00-0000000.  The table below will help determine the number to

Privacy Act Notice. -- Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payors
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, dividend and certain other payments to the 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) 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. -- Willfully falsifying
certifications of affirmations may subject you to criminal penalties including
fines and/or imprisonment.
