                         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 type of
number to give the payer.

                         NUMBER ON SUBSTITUTE FORM W-9
                                    Page 2
 . Payments of tax-exempt interest (including exempt-interest dividends under
   section 852).
 . Payments described in section 6049(b)(5) to non-resident aliens.
 . Payments on tax-free covenant bonds under section 1451.
 . Payments made by certain foreign organizations.
 . Payments made to a nominee.
Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDEN-
TIFICATION 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.
Privacy Act Notice.-- Section 6109 requires most recipients of dividend, in-
terest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are re-
quired to file tax returns. Beginning January 1, 1993, 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. Cer-
tain 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 sub-
ject to a penalty of $50 for each such failure unless your failure is due to
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 pat-
ronage 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 evi-
dence 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 im-
prisonment.
