                         NUMBER ON SUBSTITUTE FORM W-9

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.

or the Internal Revenue Service and apply for a number.

Exempt payees described above should file form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAX-PAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, SIGN AND DATE
THE FORM AND RETURN IT TO THE PAYER. IF YOU ARE A NONRESIDENT ALIEN OR A
FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH A PAYER A
COMPLETED INTERNAL REVENUE FORM W-8 (CERTIFICATE OF FOREIGN STATUS).

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 6050(A) of the Code and the regulations promulgated thereunder.

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 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 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.--Wilfully fully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
