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  nevertheless  should  file  Form  W-9 to avoid
possible erroneous backup  withholding.  FILE THIS FORM WITH THE PAYER,  FURNISH
YOUR TIN, 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 Treasury  regulations  under  sections 6041,
6041A(a),  6045, and 6050A. (All "section" references herein are to the Internal
Revenue Code of 1986)

PRIVACY ACT NOTICE -- Section  6109  requires you to furnish your correct TIN to
persons  who must file  information  returns  with the IRS to  report  interest,
dividends, and certain other income paid to you, mortgage interest you paid, the
acquisition or abandonment of secured property,  or contributions you made to an
IRA. The IRS uses the numbers for identification purposes and to help verify the
accuracy  of your tax return.  Payers must  generally  withhold  the  applicable
withholding rate of taxable interest,  dividend, and certain other payments to a
payee who does not furnish a TIN to a payer. Certain penalties may apply.

PENALTIES

(1) PENALTY  FOR FAILURE TO FURNISH TIN -- If you fail to furnish  your TIN 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--   Willfully   falsifying
certifications or affirmations may subject you to criminal  penalties  including
fines and/or imprisonment.
