            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
type of number to give the payer.

Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding.  FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, CHECK "EXEMPT" IN PART II OF THE FORM, SIGN AND DATE THE
FORM AND RETURN IT TO THE PAYER.

Certain payments other than interest, dividends, and patronage dividends, which
are not subject to information reporting are also not subject to backup
withholding.  For details, see the regulations under Section 6041, 6041(A)(a),
6045, and 6050A.

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 IRS.  IRS uses the numbers for identification
purposes.  Payers must be given the numbers whether or not recipients are
required to file tax returns.  Beginning January 1, 1993, 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 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) Failure to Report Certain Dividend and Interest Payments.  -- If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an under-
payment attributable to that failure unless there is clear and convincing
evidence to the contrary.

(3) 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.

(4) Criminal Penalty for Falsifying Information. -- 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.
