                         NUMBER ON SUBSTITUTE FORM W-9

   Guidelines for Determining the Proper Name and Identification Number to Give
the Payor.--The taxpayer identification number for an individual is the
individual's social security number. Social security numbers have nine digits
separated by two hyphens: i.e., 000-00-0000. The taxpayer identification number
for an entity is the entity's employer identification number. 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 payor.

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9

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, or
Form SS-4, Application for Employer Identification Number, at the local office
of the Social Security Administration or the Internal Revenue Service (the
"IRS") and apply for a number.

To complete the Substitute Form W-9, if you do not have a taxpayer
identification 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. Generally, 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 taxpayer 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 broker transactions
and interest and dividend payments include the following:
  . A corporation.
  . A financial institution.
  . An organization exempt from tax under section 501(a) of the Internal
    Revenue Code of 1986, as amended (the "Code"), 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.

Payments of dividends and patronage dividends not generally subject to backup
withholding include the following:

  . Payments to partnerships not engaged in a trade or business in the U.S. and
    which have at least one nonresident alien partner.
  . Payments of patronage dividends not paid in money.
  . Payments made by certain foreign organizations.
  . Payments made to a nominee.
Payments made to a nominee. Payments of interests not generally subject to
backup withholding include the following:

    section 852 of the Code).
  . Payments described in Code section 6049(b)(5) of nonresident aliens.
  . Payments on tax-free covenant bonds under section 1451 of the Code.
  . Payments made by certain foreign organizations.

Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. ENTER YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT"
ON THE FACE OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.

Privacy Act Notice.--Section 6109 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 your tax return.
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 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.
