     GUIDELINES FOR DETERMINING THE PROPER NAME AND IDENTIFICATION NUMBER 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 name and number to give the requestor.

PAYEES EXEMPT FROM BACKUP WITHHOLDING

       The following is a list of payees specifically exempted from backup
withholding:

(1)    An organization exempt from tax under section 501(a), any IRA, or a

       requirements of section 401(f)(2).

(2)    The United States or of any of its agencies or instrumentalities.

(3)    A state, the District of Columbia, a possession of the United States, or

       instrumentalities.

         Exempt payees described at left should file Form W-9 to avoid possible
erroneous backup withholding. FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE
"EXEMPT" IN PART II OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE
PAYER. If you are a nonresident alien or a foreign entity not subject to backup
withholding, give the payer a completed Form W-8, Certificate of Foreign Status.

PRIVACY ACT NOTICE.

         Section 6109 of the Internal Revenue Code requires you to provide your
correct TIN to persons who must file information 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 Archer MSA. The IRS uses the numbers for
identification purposes and to help verify the accuracy of your return. The IRS
may also provide this information to the Department of Justice for criminal and
civil litigation and to cities, states and the District of Columbia to carry out
their tax laws. The IRS may also disclose this information to other countries
under a tax treaty, or to Federal and state agencies to enforce Federal nontax
criminal laws and to combat terrorism.

         You must provide your TIN whether or not you are required to file a tax
return. Payers must generally withhold 28 percent of taxable interest, dividend
and certain other payments to a payee who does not furnish a TIN to a payer.
Certain penalties may also apply.

PENALTIES

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

         (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.

REVENUE SERVICE.
