GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE
PAYER.-- Social Security numbers have nine digits separated by two hyphens:
i.e. 000-00-0000. Employer identification numbers have nine digits separated by
only one hyphen: i.e. 00-0000000. The table below will help determine the
number to give 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, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT
TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS,
ALSO SIGN AND DATE THE FORM.
 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(a),
6045, and 6050A of the Code and the Treasury regulations promulgated
thereunder.
 
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. Payers must generally withhold
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 a reasonable cause and not to willful neglect.
   
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and
convincing evidence to the contrary.     
   
(3) 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.     
   
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.-- Falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.
