            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         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
number to give the payer.

                                     Page 2
Obtaining a Number

If you don't have a taxpayer identification number or you don't know your
number, obtain Form SS-5, Application for a Social Security Number Card (for
resident individual), or Form SS-4, Application for Employer Identification
Number (for businesses and all other entities), 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 Internal
Revenue Service.

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 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, 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 United
    States or a possession of the United States.
  . A real estate investment trust.
  . A common trust fund operated by a bank under section 584(a)
  . An exempt charitable remainder trust, or a non-exempt trust described in
    section 4947(a)(1).
  . An entity registered at all times during the year 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 (i) this interest is
    $600 or more (ii) this interest is paid in the course of the payor's trade
    or business and (iii) you have not provided your correct taxpayer identi-
    fication number to the payor.

  . Payments of tax-exempt interest (including exempt-interest dividends un-
    der 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
IDENTIFICATION NUMBER, WRITE "EXEMPT" IN PART 2, SIGN AND DATE THE FORM AND
RETURN IT TO THE PAYOR.

 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 dividends, inter-
est, or other payments to give taxpayer identification numbers to payors 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. Payors must be
given the numbers whether or not recipients are required to file tax returns.
Payors must generally withhold 31% of taxable interest, dividends, and certain
other payments to a payee who does not furnish a taxpayer identification number
to a payor. 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 payor, 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 Statements 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.--If you falsify certifications
or affirmations you are subject to criminal penalties including fines and/or
imprisonment.
