TAXPAYER IDENTIFICATION NUMBER, CHECK "EXEMPT" IN PART II OF THE FORM, 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

PRIVACY ACT NOTICE.--Section 6109 of the Code requires most recipients of
dividend, 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. Payers must be given the numbers whether or not
recipients are required to file tax returns. Beginning January 1, 2002, payers
must generally withhold a portion 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 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.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment. FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE
INTERNAL REVENUE SERVICE.
