Department of the Treasury Internal Revenue Service

         Instructions for the Requester of Form W-9 (Rev. December 1996)
          Request for Taxpayer Identification Number and Certification
  SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE UNLESS OTHERWISE NOTED.

These  instructions  supplement  the  instructions  on  the  Form  W-9  for  the
requester.

CHANGES TO NOTE

INDIVIDUAL TAXPAYER  IDENTIFICATION  NUMBER  (ITIN).--Form W-9 (or an acceptable
substitute) is used by persons required to file information returns with the IRS
to get the payee's correct TIN. For  individuals,  the TIN is generally a social
security number (SSN).

     However, in some cases, individuals who become U.S. resident aliens for tax
purposes  are not  eligible to obtain an SSN.  This  includes  certain  resident
aliens who must receive information returns but who cannot obtain an SSN.

     These  individuals must apply for an ITIN on Form W-7,  Application for IRS
Individual  Taxpayer  Identification  Number,  unless  they have an  application
pending for an SSN. Individuals who have an ITIN must provide it on Form W-9.

TIN  APPLIED  FOR (60 DAY  RULE).--The  instructions  clarify  that  the  60-day
exemption  from  backup   withholding  upon   presentation  of  an  awaiting-TIN
certificate applies only to interest and dividend payments, and certain payments
made with respect to readily tradable instruments. Other payments are subject to
backup withholding.

SUBSTITUTE FORM W-9

You may develop and use your own Form W-9 (a substitute Form W-9) if its content
is substantially similar to the IRS's official Form W-9 and it satisfies certain
certification requirements.

     You may  incorporate a substitute  Form W-9 into other  business  forms you
customarily use, such as account  signature cards,  provided the  certifications
that (1) the  payee's  TIN is correct and (2) the payee is not subject to backup
withholding due to failure to report interest and dividend income,  shown on the
official Form W-9, are clearly set forth. You may not:

     1. Use a substitute Form W-9 that requires the payee, by signing,  to agree
to provisions unrelated to the required certifications.

     2. Imply that a payee may be subject to backup withholding unless the payee
agrees to provisions on the  substitute  form that are unrelated to the required
certifications.

     A substitute Form W-9 that contains a separate  signature line just for the
certifications  satisfies the requirement that the certifications be clearly set
forth.



     If a single  signature  line is used for the  required  certifications  and
other provisions,  the  certifications  must be highlighted,  boxed,  printed in
bold-face  type,  or  presented in some other manner that causes the language to
stand  out  from  all  other  information  contained  on  the  substitute  form.
Additionally, the following statement must be presented in the same manner as in
the preceding  sentence and must appear  immediately  above the single signature
line:  "The  Internal  Revenue  Service  does not  require  your  consent to any
provision  of this  document  other than the  certifications  required  to avoid
backup withholding."

     Generally,  the rules  concerning  the  signature on a substitute  Form W-9
apply to those completed after 1996. However,  the effective date is extended to
July 1, 1997, if the payer:

*    Must  obtain the  approval  of a  government  authority  for changes to the
     format of its substitute Form W-9, and

*    Applied for that approval by September 30, 1996, and

*    Thereafter actively pursues that approval.

     If you use a substitute  form, the instructions do not have to be furnished
to the  payee.  The payee only  needs to be  instructed  orally or in writing to
strike  out  the   language  of  the   certification   that   relates  to  payee
underreporting,  if the payee is subject to backup  withholding  due to notified
payee  underreporting.  However,  you are  encouraged  to  provide  instructions
relevant to the account, especially if the payee requests them.

TIN APPLIED FOR

If the payee returns a properly completed Form W-9 with "Applied For" written in
Part I (i.e.,  an  "awaiting  TIN"  certificate),  the payee must give you a TIN
within 60  calendar  days to avoid  backup  withholding.  You may use one of the
following rules to backup withholding. You may use one of the following rules to
backup  withhold  during this 60-day period on  reportable  interest or dividend
payments and certain payments with respect to readily tradable instruments.

RESERVE RULE.--If a payee withdraws more than $500 at one time during the 60-day
period,  you must backup  withhold on any  reportable  payments  made during the
period,  unless the payee  reserves 31% of all  reportable  payments made to the
account during the period.

ALTERNATIVE  RULE  (OPTION  1).--You  must  backup  withhold  on any  reportable
payments if the payee makes a withdrawal  from the account  after the close of 7
business  days  after  you  receive  the  awaiting-TIN  certificate.   Treat  as
reportable  payments  all cash  withdrawals  in an amount  up to the  reportable
payments made from the day after you receive the awaiting-TIN certificate to the
day of withdrawal.

ALTERNATIVE  RULE  (OPTION  2).--You  must  backup  withhold  on any  reportable
payments made to the payee's account,  regardless of whether the payee makes any
withdrawals.  Backup  withholding  under this  option must begin no later than 7
business days after you receive the awaiting-TIN certificate.

A Guide to Backup  Withholding,  or Pub. 1281, Backup Withholding on Missing and
Incorrect TINs.

JOINT FOREIGN PAYEES

If the first  payee  listed on an  account  gives you Form W-8,  Certificate  of
Foreign Status, or a similar statement signed under penalties of perjury, backup
withholding applies unless:

     1. Every joint payee provides the statement regarding foreign status; or

     2. Any one of the joint payees who has not established foreign status gives
you a TIN.

     If any one of the joint payees who has not established foreign status gives
you a TIN,  that  number  is the TIN that  must be used for  purposes  of backup
withholding and information reporting.

NAMES AND TINS TO USE FOR INFORMATION REPORTING

Show the full name and address as provided on Form W-9 on the information return
filed with the IRS and on the copy furnished to the payee.  If you made payments
to more than one  payee or the  account  is in more than one name,  enter on the
first name line ONLY the name of the payee whose TIN is shown on the information
return.  Show the names of any  other  individual  payees in the area  below the
first name line, if desired.

SOLE  PROPRIETORS.--You  must show the individual's name on the first name line.
On the second name line,  you may enter the business name or "doing  business as
(DBA)" if provided.  You may not enter only the business  name. For the TIN, you



may enter  either the  individual's  SSN or the employer  identification  number
(EIN) of the business. However, the IRS prefers that you show the SSN.

NOTICES FROM THE IRS

The IRS will send you a notice if the  payee's  name and TIN on the  information
return  you filed do not match  the  IRS's  records.  You may have to send a "B"
notice to the payee to solicit  another TIN. See Pubs.  1679 and 1281 for copies
of the two types of "B" notices.
