                         NUMBER ON SUBSTITUTE FORM W-9

     GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE
PAYOR. Social Security numbers and individual taxpayer identification numbers
(ITIN) 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 payor.

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

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 Card, Form W-7,
Application for IAS Individual Taxpayer Identification Number or Form SS-4,
Application for Employer Identification Number (for business and all other
entities), at the local office of the Social Security Administration or the
Internal Revenue Service and apply for a number.

To complete Substitute Form W-9 if you do not have a taxpayer identification
number, write "Applied For" in the space for the taxpayer identification number,
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 of interest
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), if the account satisfies the
    requirements of Section 401(f)(2).

  - The United States or any agency or instrumentalities.

  - A state, the District of Columbia, a possession of the United States, or any
    political subdivision or instrumentality thereof.

  - A foreign government, a political subdivision of a foreign government, or
    any 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, the District of Columbia or a possession of the United States.

  - A real estate investment trust.

  - A common trust fund operated by a bank under section 584(a) of the Code.

  - An exempt charitable remainder trust, or a non-exempt trust described in
    section 4947(a)(I) of the Code.

  - An entity registered at all times under the Investment Company Act of 1940.

  - A foreign central bank of issue.

  - A middleman known in the investment community as a nominee or custodian.

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 payor's trade or business and you have not provided
    your correct taxpayer identification number to the payor.

  - Payments of tax-exempt interest (including exempt-interest dividends under
    Section 852 of the Code).

  - Payments described in Section 6049(b)(5) of the Code to nonresident aliens.

  - Payments made by certain foreign organizations.

  - Mortgage or student loan interest paid to you.

Exempt payees described above should file a Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYOR, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM. SIGN AND DATE THE
FORM AND RETURN IT TO THE PAYOR. IF YOU ARE A NONRESIDENT ALIEN OR A FOREIGN
ENTITY NOT SUBJECT TO BACKUP WITHHOLDING FILE WITH A PAYOR A COMPLETED INTERNAL
REVENUE FORM W-8BEN (CERTIFICATE FOREIGN STATUS OF BENEFICIAL OWNER FOR UNITED
STATES TAX WITHHOLDING) OR OTHER APPROPRIATE FORM W-8).

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 regulations under Section 6041, 6041A, 6042,
6044, 6045, 6049, 6050(A), and 6050(N) of the Code and the regulations
promulgated thereunder.

PRIVACY ACT NOTICE -- Section 6109 requires most recipients of dividends,
interest, or other payments to give taxpayer identification numbers to payors
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payors must be given the numbers whether or not
recipients are required to file tax returns. Payors must generally withhold
between 28% and 31%, depending on the year, 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 wilful neglect.

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

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

FOR ADDITIONAL INFORMATION, CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.
