FILE THIS FORM WITH THE PAYOR, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" IN PART 2, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYOR. Certain payments other than interest, dividends, and patronage dividends that are not subject to information reporting are also not subject to backup withholding.

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 IRS. 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 at the Withholding Rate 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) Civil Penalty for False Statements 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.--If you willfully falsify certifications or affirmations, you may be subject to criminal penalties including fines and/or imprisonment.
