and apply for a number.

     be subject to backup withholding if this interest is $600 or more and is
     paid in the course of the Payer's trade or business and you have not
     provided your correct taxpayer identification number to the Payer.

Exempt Payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR 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, which
are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under Section 6041, 6041(A),
6045, 6050A and 6050N.

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. Payers must be given the numbers whether or not recipients are
required to file tax returns. Payers must generally withhold up to 31% 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 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.
