                         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.

Number (for alien individuals required to file U.S. tax returns), at the local
office of the Social Security Administration or the Internal Revenue Service

follows:

ENTER YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ACROSS THE FACE OF
THE FORM, SIGN, DATE, AND RETURN THE FORM TO THE PAYER.

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 sections 6041, 6041A(a), 6042, 6044, 6045, 6049,
6050A and 6050N and the regulations thereunder.

Privacy Act Notice.--Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes and to help verify the accuracy of tax reforms. 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. Payers must be given the numbers whether or not
recipients are required to file tax returns. Payers must generally withhold
31% of taxable interest, dividend, and certain other payments to a payee who
does not furnish a taxpayer identification number to a payer. 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) 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.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
(4) Misuse of Taxpayer Identification Numbers.--If the payer discloses or uses
taxpayer identification numbers in violation of Federal law, the payer may be
subject to civil and criminal penalties.
