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




Guidelines for Determining the Proper Identification Number to Give the Payer. 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 payer.

     Privacy Act Notice. Section 6109 requires you to provide your correct
taxpayer identification number to persons who must file information returns with
the IRS to report interest, dividends and certain other income paid to you. 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. 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. Payers
must be given the numbers whether or not recipients are required to file tax
returns. Payers must generally withhold 28% of taxable interest, dividends, and
certain other payments to a payee who does not furnish a taxpayer identification
number to a payee. Certain penalties may also apply.

Penalties:

(1)   Penalty for failure to furnish Taxpayer Identification Number. If you fail
      to furnish your correct 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.
