GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                          NUMBER ON SUBSTITUTE FORM W-9
                         (SECTION REFERENCES ARE TO THE
                  INTERNAL REVENUE CODE OF 1986, AS AMENDED)


GUIDELINES FOR DETERMINING THE PROPER TAXPAYER IDENTIFICATION NUMBER ("TIN") TO
GIVE THE PAYER--Social Security numbers ("SSNs") have nine digits separated by
two hyphens: i.e., 000-00-0000. Employer identification numbers ("EINs") have
nine digits separated by only one hyphen: i.e., 00-0000000. The table below
will help determine the number to give the payer.

You must enter your TIN in the appropriate box. If you are a resident alien and
you do not have and are not eligible to get an SSN, your TIN is your IRS
individual taxpayer identification number ("ITIN"). Enter it in the social
security number box. If you do not have an ITIN, see HOW TO GET A TIN below.

If you are a sole proprietor and you have an EIN, you may enter either your SSN
or EIN. However, using your EIN may result in unnecessary notices to the person
requesting your TIN.

             GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                          NUMBER ON SUBSTITUTE FORM W-9
                         (SECTION REFERENCES ARE TO THE
                   INTERNAL REVENUE CODE OF 1986, AS AMENDED)


PURPOSE OF FORM--A person who is required to file an information return with
the IRS must get your correct TIN to report, for example, income paid to you,
real estate transactions, mortgage interest you paid, the acquisition or
abandonment of secured property, cancellation of debt, or contributions you
made to an IRA. Use Form W-9 only if you are a U.S. person (including a
resident alien) to give your correct TIN to the person requesting your TIN and,
when applicable, (1) to certify the TIN you are giving is correct (or you are
waiting for a number to be issued), (2) to certify you are not subject to
backup withholding, or (3) to claim exemption from backup withholding if you
are an exempt payee. If you are a nonresident alien or a foreign entity not
subject to backup withholding, give the requester a completed Form W-8,
Certificate of Foreign Status.

WHAT IS BACKUP WITHHOLDING?--Persons making certain payments to you must
withhold and pay to the IRS 30.5% of such payments under certain conditions.
This is called "backup withholding." Payments that could be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.

If you give the requester your correct TIN, make the proper certifications, and
report all your taxable interest and dividends on your tax return, payments you
receive will not be subject to backup withholding. Payments you received will
be subject to backup withholding if:

1.    You do not furnish your TIN to the requester, or
2.    The IRS tells the requester that you furnished an incorrect TIN, or
3.    The IRS tells you that you are subject to backup withholding because you
      did not report all your interest and dividends on your tax return (for
      reportable interest and dividends only), or
4.    You do not certify to the requester that you are not subject to backup
      withholding (for reportable interest and dividend accounts opened after
      1983 only), or
5.    You do not certify your TIN

Certain payees and payments are exempt from backup withholding and information
reporting. See below.

HOW TO GET A TIN: If you do not have a TIN, apply for one immediately. To apply
for an SSN, get Form SS-5 from your local Social Security Administration
office. Get Form W-7 to apply for an ITIN or Form SS-4 to apply for an EIN. You
can get Forms W-7 and SS-4 from the IRS by calling 1-800-TAX-Form
(1-800-829-3676) or from the IRS's Internet Web Site at www.irs.gov.

If you do not have a TIN, check the box titled "Applied For" in the space for
the TIN, sign and date the form, and give it to the requester.

NOTE: Checking the box titled "Applied For" on the form means that you have
already applied for a TIN OR that you intend to apply for one soon.

As soon as you receive your TIN, complete another Form W-9, include your TIN,
sign and date the form, and give it to the requester.


PAYEES EXEMPT FROM BACKUP WITHHOLDING

Individuals (including sole proprietors) are NOT exempt from backup
withholding. Corporations are exempt from backup withholding for certain
payments, such as interest and dividends.

If you are exempt from backup withholding, you should still complete this form
to avoid possible erroneous backup withholding Enter your correct TIN in Part
I, write "Exempt" in Part II, and sign and date the form.

PRIVACY ACT NOTICE--Section 6109 requires you to give your correct TIN to
persons who must file information returns with the IRS to report interest,
dividends, and certain other income paid to you, mortgage interest you paid,
the acquisition or abandonment of secured property, cancellation of debt, or
contributions you made to an IRA or MSA. The IRS uses the numbers for
identification purposes and to help verify the accuracy of your tax return. The
IRS may also provide this information to the Department of Justice for civil
and criminal litigation and to cities, states, and the District of Columbia to
carry out their tax laws.

You must provide your TIN whether or not you are required to file a tax return.
Payers must generally withhold 30.5% of taxable interest, dividend, and certain
other payments to a payee who does not give a TIN to a payer. Certain penalties
may also apply.



PENALTIES

(1) FAILURE TO FURNISH TIN--If you fail to furnish your TIN to a requester, 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 that results in no backup
withholding, you are subject to a penalty of $500.


                                       2




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

(4) MISUSE OF TINS--If the requester discloses or uses TINs in violation of
Federal law, the requester may be subject to civil and criminal penalties.
