000-00-0000. Employer identification numbers have nine digits separated by only
one hyphen: e.g., 00-0000000. The table below will help determine the name and
number to give the payer.

OBTAINING A TAXPAYER IDENTIFICATION NUMBER

    Persons without a taxpayer identification number should apply for one and
write "Applied for" in Part I of Substitute Form W-9. Individuals should file
Form SS-5, Application for a Social Security Card (or, in the case of resident
aliens who do not have and are not eligible for Social Security numbers, Form
W-7, Application for IRS Individual Taxpayer Identification Number),
corporations, partnerships or other entities should file Form SS-4, Application
for Employer Identification Number. Form SS-5 may be obtained from local Social
Security Administration offices. Forms W-7 and SS-4 may be obtained from the IRS
by calling 1-800-TAX-FORM (1-800-829-3676).

NOTE:  Writing "Applied for" in Part I means that you have already applied for a
       TIN or that you intend to apply for one soon.

6049, 6050A, and 6050N of the IRC, and their regulations.

CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING--If you make a
false statement with no reasonable basis that results in no backup withholding,
you are subject to a $500 penalty.

CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Willfully falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.

PRIVACY ACT NOTICE--Section 6109 of the IRC requires most recipients of
dividend, 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 individuals' tax
returns. The IRS may also provide this information to the Department of Justice
for civil and criminal litigation and to states, cities and the District of
Columbia to help carry out their tax laws.

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.
