PRIVACY ACT NOTICE

IRC 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. The 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 30% 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.
