000-00-0000. Employer Identification Numbers have nine digits separated by only
one hyphen: i.e. 00-0000000. The table below will help you determine the number

EXEMPT PAYEES DESCRIBED ABOVE SHOULD FILE SUBSTITUTE FORM W-9 TO AVOID POSSIBLE
ERRONEOUS BACKUP WITHHOLDING. CHECK THE BOX ON THE FACE OF THE FORM IN PART 2,
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, 6041A, 6042,
6044, 6045, 6049, 6050A, and 6050N of the Internal Revenue Code.

PRIVACY ACT NOTICE -- Section 6109 of the Internal Revenue Code requires most
recipients to give their correct Taxpayer Identification Number 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 tax returns. Payers must be given
the numbers whether or not recipients are required to file tax returns. Payers
must generally withhold a certain percentage (currently 28%) 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 requester, 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 backup
withholding, you are subject to a $500 penalty.
(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 Taxpayer Identification Numbers. If the requester discloses or
uses taxpayer identification numbers in violation of federal law, the requester
may be subject to civil and criminal penalties.
