GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER
                             ON SUBSTITUTE FORM W-9
 
SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE.
 
     Purpose of Form. -- A person who is required to file an information return
with the IRS must get your correct taxpayer identification number (TIN) to
report, for example, income paid to you, real estate transactions, mortgage
interest you paid, acquisition or abandonment of secured property, cancellation
of debt, or contributions you made to an IRA.
 
     Use Form W-9 to give your correct TIN to the person requesting it (the
requester) and, when applicable, to:
 
     1. Certify the TIN you are giving is correct (or you are waiting for a
number to be issued),
 
     2. Certify you are not subject to backup withholding,
 
     3. Claim exemption from backup withholding if you are an exempt payee.
 
     Note: If a requester gives you a form other than a W-9 to request your TIN,
you must use the requester's form if it is substantially similar to this Form
W-9.
 
     What is Backup Withholding? -- Persons making certain payments to you must
withhold and pay to the IRS 31% of such payments under certain conditions. This
is called 'backup withholding.' Payments that may be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.
 
     If you give the requester your correct TIN, make the proper certifications,
and report all your taxable interest and dividends on your tax return, payments
you receive will not be subject to backup withholding. Payments you receive will
be subject to backup withholding if:
 
     1. You do not furnish your TIN to the requester, or
 
     2. The IRS tells the requester that you furnished an incorrect TIN, or
 
     3. The IRS tells you that you are subject to backup withholding because you
did not report all your interest and dividends on your tax return (for
reportable interest and dividends only), or
 
     4. You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened
after 1983 only), or
 
     5. You do not certify your TIN when required. See the Part III instructions
on page 3 for details.

 
     Certain payees and payments are exempt from backup withholding. See the
Part II instructions and the separate Instructions for the Requester of Form
W-9.
 
PENALTIES
 
     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.
 
     Civil Penalty for False Information With Respect to Withholding. -- If you
make a false statement with no reasonable basis that results in no backup
withholding, you are subject to a $500 penalty.
 
     Criminal Penalty for Falsifying Information. -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
 
     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.
 
SPECIFIC INSTRUCTIONS
 
     Name. -- If you are an individual, you must generally enter the name shown
on your social security card. However, if you have changed your last name, for
instance, due to marriage, without informing the Social Security Administration
of the name change, enter your first name, the last name shown on your social
security card, and your new last name.
 
     If the account is in joint names, list first and then circle the name of
the person or entity whose number you enter in Part I of the form.



     Sole Proprietor. -- You must enter your individual name as shown on your
social security card. You may enter your business, trade, or 'doing business as'
name on the business name line.
 
     Other Entities. -- Enter the business name as shown on required Federal tax
documents. This name should match the name shown on the charter or other legal
document creating the entity. You may enter any business, trade or 'doing
business as' name on the business name line.
 
PART I -- TAXPAYER IDENTIFICATION NUMBER
 
     You must enter your TIN in the appropriate box. If you are a resident alien
and you do not have and are not eligible to get an SSN, your TIN is your IRS
individual taxpayer identification number (ITIN). Enter it in the social
security number box. If you do not have an ITIN, see How To Get a TIN below.
 
     If you are a sole proprietor and you have an EIN, you may enter either your
SSN or EIN. However, using your EIN may result in unnecessary notices to the
requester.

 
     Note: See the chart on pages 4 and 5 for further clarification of name and
TIN combinations.
 
     How to Obtain a TIN. -- If you do not have a TIN, apply for one
immediately. To apply for an SSN, get Form SS-5 from your local Social Security
Administration office. Get Form W-7 to apply for an ITIN or Form SS-4 to apply
for an EIN. You can get Forms W-7 and SS-4 from the IRS by calling
1-800-TAX-FORM (1-800-829-3676).
 
     If you do not have a TIN, write 'Applied For' in the space for the TIN,
sign and date the form, and give it to the requester. For interest and dividend
payments, and certain payments made with respect to readily tradable
instruments, you will generally have 60 days to get a TIN and give it to the
requester. Other payments are subject to backup withholding.
 
     Note: Writing 'Applied For' means that you have already applied for a TIN
OR that you intend to apply for one soon.
 
PART II -- FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING
 
     Individuals (including sole proprietors) are not exempt from backup
withholding. Corporations are exempt from backup withholding for certain
payments, such as interest and dividends. For more information on exempt payees,
see the separate instructions for the Requester of Form W-9.
 
     If you are exempt from backup withholding, you should still complete this
form to avoid possible erroneous backup withholding. Enter your correct TIN in
Part I, write 'Exempt' in Part II, and sign and date the form.
 
     If you are a nonresident alien or a foreign entity not subject to backup
withholding, give the requester a completed Form W-8, Certificate of Foreign
Status.
 
PART III -- CERTIFICATION
 
     For a joint account, only the person whose TIN is shown in Part I should
sign (when required).
 
     1. Interest, Dividend, and Barter Exchange Accounts Opened Before 1984 and
Broker Accounts Considered Active During 1983. You give your correct TIN, but
you do not have to sign the certification.
 
     2. Interest, Dividend, Broker and Barter Exchange Accounts Opened After
1983 and Broker Accounts Considered Inactive During 1983. You must sign the
certification or backup withholding will apply. If you are subject to backup
withholding and you are merely providing your correct TIN to the requester, you
must cross out item 2 in the certification before signing the form.
 
     3. Real Estate Transactions. You must sign the certification. You may cross
out item 2 of the certification.
 
     4. Other Payments. You must give your correct TIN, but you do not have to
sign the certification unless you have been notified that you have previously

given an incorrect TIN. 'Other payments' include payments made in the course of
the requester's trade or business for rents, royalties, goods (other than bills
for merchandise), medical and health care services (including payments to
corporations), payments to a nonemployee for services (including attorney and
accounting fees), and payments to certain fishing boat crew members.
 
     5. Mortgage Interest Paid by You, Acquisition or Abandonment of Secured
Property, Cancellation of Debt, or IRA Contributions. You must give your correct
TIN, but you do not have to sign the certification.



PRIVACY ACT NOTICE
 
     Section 6109 of the Internal Revenue Code requires you to give your correct
TIN to persons who must file information returns 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. 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.
 
     You must provide your TIN whether or not you are required to file a tax
return. Payers must generally withhold 31% of taxable interest, dividend, and
certain other payments to a payee who does not give a TIN to a payer. Certain
penalties may also apply.
