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.

IDENTIFICATION NUMBER ON PART III OF THE FORM, WRITE "EXEMPT" ON THE FACE OF THE
FORM AND SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.

    Payments that are not subject to information reporting are also not subject
to backup withholding.  For details, see sections 6041, 6041A(a), 6042, 6044,
6045, 6049, 6050A, and 605ON of the Code and their regulations.

PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividends,
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 and to help verify the accuracy of your tax return.
Payers must be given the numbers whether or not recipients are required to file
a tax return.  Payers must generally withhold 31% of taxable interest,
dividends, 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.
