by only one hyphen: i.e., 00-0000000. The table below will help determine the

Obtaining a Number
If you do not have a taxpayer identification number or you do not know your
number, obtain Form SS-5, Application for a Social Security Number Card (for
resident individuals), Form SS-4, Application for Employer Identification Num-
ber (for businesses and all other entities), or Form W-7 for International
Taxpayer Identification Number (for alien individuals required to file U.S.
Tax returns), at an office of the Social Security Administration or the Inter-
nal Revenue Service.
To complete the Substitute Form W-9, if you do not have a taxpayer identifica-
tion number, write "Applied For" in the space for the taxpayer identification
number in Part 1, sign and date the Form, and give it to the requester. Gener-
ally, you will then have 60 days to obtain a taxpayer identification number
and furnish it to the requester. If the requester does not receive your tax-
payer identification number within 60 days, backup withholding, if applicable,
will begin and will continue until you furnish your taxpayer identification
number to the requester.
Payees Exempt from Backup Withholding
Payees specifically exempted from backup withholding on ALL payments include
the following:
. A corporation.
. A financial institution.
. An organization exempt from tax under section 501(a), or an individual
retirement plan, or a custodial account under section 403(b)(7).
. The United States or any agency or instrumentality thereof.
. A State, the District of Columbia, a possession of the United States, or
any subdivision or instrumentality thereof.
. A foreign government, or a political subdivision, agency or
instrumentality thereof.
. An international organization or any agency or instrumentality thereof.
. A registered dealer in securities or commodities registered in the U.S.
or a possession of the U.S.

. An exempt charitable remainder trust, or a nonexempt trust described in
section 4947(a)(1).
. An entity registered at all times under the Investment Company Act of
1940.
. A foreign central bank of issue.
Payments of dividends and patronage dividends not generally subject to backup
withholding include the following:
. Payments to nonresident aliens subject to withholding under section 1441.
. Payments to partnerships not engaged in a trade or business in the U.S.
and which have at least one nonresident partner.
. Payments of patronage dividends where the amount received is not paid in
money.
. Payments made by certain foreign organizations.
. Payments made to a nominee.
Payments of interest not generally subject to backup withholding include the
following:
. Payments of interest on obligations issued by individuals.
Note: You may be subject to backup withholding if this interest is $600 or
more and is paid in the course of the payer's trade or business and you
have not provided your correct taxpayer identification number to the
payer.
. 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 a Substitute Form W-9 to avoid pos-
sible erroneous backup withholding.
FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION 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 with-
holding. For details, see the regulations under sections 6041, 6041A(a), 6045,
and 6050A.
Privacy Act Notice.--Section 6109 requires most recipients of dividend, inter-
est, or other payments to give taxpayer identification numbers to payers who
must report the payments to the IRS. The IRS uses the numbers for identifica-
tion 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, dividends, and certain other payments to a payee who does not fur-
nish 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 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.
