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.

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.  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 30% 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) 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.

(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.
