OBTAINING A NUMBER
If you do not have a taxpayer identification number or you do not know your
number, obtain Form SS-5, Application for a Social Security Number Card (for
resident individuals), Form SS-4, Application for Employer Identification Number
(for businesses and all other entities), or Form W-7 for International Taxpayer
Identification Number (for alien individuals required to file U.S. tax returns),
at an office of the Social Security Administration of the Internal Revenue
Service.
To complete Substitute Form W-9, if you do not have a taxpayer
identification number, check the "Awaiting TIN" box in Part 3, sign and date the
Form, and give it to the requester.
Generally, you will then have 60 days to obtain a taxpayer identification
number and furnish it to the requester. If the requester does not receive your
taxpayer identification number within 60 days, backup withholding tax, if
applicable, will begin and will continue until you furnish your taxpayer
identification number to the requester.

include the following:*
- A corporation.

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.-If you fail
to furnish your 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 tax, you are subject to a $500 penalty.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.-If you willfully falsify
certifications or affirmations, you are subject to criminal penalties
including fines and/or imprisonment.
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.
SIGN AND DATE THE FORM AND RETURN IT TO 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 regulations under sections 6041, 6041(A)(a),
6045, and 6050A.
PRIVACY ACT NOTICES. Section 6109 requires most recipients of dividends,
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 your tax return. Payers must be
given the numbers whether or not recipients are required to file tax returns.
Payers must generally withhold 31% of taxable interest, dividends, and certain
other payments to a payee who does not furnish a taxpayer identification number
to a payer. Certain penalties may also apply.
