List first and circle the name of the person whose number you furnish. If only one person on a joint account has a Social Security Number, that person's number must be furnished.

(2)

Circle the minor's name and furnish the minor's Social Security Number.

(3)

You must show your individual name, and you may also enter your business or "doing business as" name on the "Business name/disregarded entity" name line. You may use either your Social Security Number or Employer Identification Number (if you have one), but the IRS encourages you to use your Social Security Number.

(4)

List first and circle the name of the trust, estate, or pension trust. (Do not furnish the taxpayer identification number of the personal representative or trustee unless the legal entity itself is not designated in the account title.) Also see Special rules for partnerships on page 1 of Form W-9 instructions.

*Note. Grantor also must provide a Form W-9 to trustee of trust.

Note: If no name is circled when more than one name is listed, the number will be considered to be that of the first name listed.

Obtaining a Number

        If you don't have a taxpayer identification number or you don't know your number, obtain Form SS-5, Application for a Social Security Number Card (for individuals), or Form SS-4, Application for Employer Identification Number (for business and all other entities), and apply for a number. These forms are available at the local office of the Social Security Administration or the Internal Revenue Service, on the internet at http://www.irs.gov, or by calling 1 (800) TAX-FORM.

        Exempt payees described above should file the Substitute Form W-9 to avoid possible erroneous backup withholding.

        FILE THIS FORM WITH THE PAYOR, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, CHECK THE BOX IN PART 3 OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYOR. IF YOU ARE A NONRESIDENT ALIEN OR A FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH THE PAYOR THE APPROPRIATE COMPLETED IRS 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 Sections 6041, 6041A, 6042, 6044, 6045, 6049, 6050A and 6050N of the Code and the regulations promulgated thereunder.

        Privacy Act Notice.    Section 6109 of the Code requires most recipients of dividends, interest or other payments to give a taxpayer identification number ("TIN") to payors who must report the payments to the IRS. The IRS uses the TIN for identification purposes and to help verify the accuracy of your tax returns. Payors must be given a TIN whether or not recipients are required to file tax returns. Payors must generally withhold a percentage (currently 28%) of taxable interest, dividends and certain other payments to a payee who does not furnish a TIN to a payor. Certain penalties may also apply.

Penalties

(1)    Penalty for Failure to Furnish TIN.    If you fail to furnish your correct TIN to a payor, 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 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 TIN.    If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.
