                       Substitute Form W-9 with Guidelines



                               Substitute Form W-9


o  Purpose of the Substitute Form W-9

   Each tendering  Limited Partner is required to provide to the Partnership its
correct Taxpayer  Identification  Number ("TIN") on Substitute Form W-9 which is
provided below,  and to certify whether the Limited Partner is subject to backup
withholding of federal  income tax. If the  Partnership is not provided with the
correct TIN, the Limited Partner may be subject to a $500 penalty imposed by the
Internal  Revenue  Service  (the  "IRS").  In  addition,  failure to provide the
information on Substitute Form W-9 may subject the tendering  Limited Partner to
31% federal  income tax  withholding on the payment of the purchase price of all
Units purchased by the Offerors from the Limited Partner pursuant to this Offer.

o  Instructions for filling out the Substitute Form W-9

   Each tendering  Limited  Partner must fill out the Substitute  Form W-9 below
by: (1) inserting  their TIN; (2) certifying  whether the Limited Partner is (a)
subject to backup  withholding  of federal  income tax and (b) a U.S.  person or
resident alien; and (3) signing the form.

   If the tendering  Limited  Partner is an  individual,  the TIN is the Limited
Partner's social security number.

   If the  tendering  Limited  Partner  has  been  notified  by the IRS that the
Limited Partner is subject to backup withholding, the Limited Partner must cross
out item (2) of the  "Certification"  box of  Substitute  Form W-9,  unless  the
Limited  Partner has since been notified by the IRS that the Limited  Partner is
no longer subject to backup  withholding.  If backup  withholding  applies,  the
Partnership  is  required to withhold  31% of any  payments  made to the Limited
Partner.  Backup withholding is not an additional tax. Rather, the tax liability
of persons  subject to backup  withholding  will be reduced by the amount of tax
withheld.  If  withholding  results in an  overpayment of taxes, a refund may be
obtained from the IRS.

   If the  tendering  Limited  Partner has not been issued a TIN and has applied
for one or  intends to apply for one in the near  future,  the  Limited  Partner
should write  "Applied  For" in the space  provided for the TIN in Part I of the
Substitute Form W-9, and sign and date the Substitute Form W-9. If "Applied For"
is written in Part I and the  Partnership  is not provided  with a TIN within 60
days, the Partnership will withhold 31% on all payments of the purchase price to
the Limited Partner until a TIN is provided to the Partnership.

   Certain Limited  Partners  (including,  among others,  all  corporations  and
certain  foreign  individuals)  are not subject to these backup  withholding and
reporting  requirements.  In order for a foreign  individual  to  qualify  as an
exempt  recipient,  the  individual  must submit an Internal  Revenue  Form W-8,
signed under penalties of perjury, attesting to such individual's exempt status.
A Form W-8 may be obtained  from Maxus Real Property  Investors - Four,  L.P. at
the   address  and   telephone   number   provided  in  Section  16,   "Address;
Miscellaneous" of the Offer to Purchase.

   For complete  instructions  on how to fill out Substitute  Form W-9, refer to
the Guidelines enclosed.

                                                                          (OVER)

Part  II --  For  payees  exempt  from  backup  withholding,  see  the  enclosed
Guidelines and complete as instructed therein.

Certification -- Under penalties of perjury, I certify that:

(1) The number shown on this form is my correct Taxpayer  Identification  Number
(or I am waiting for a number to be issued to me), and

(2) I am not subject to backup  withholding  either because (a) I am exempt from
backup withholding, (b) I have not been notified by the Internal Revenue Service
(the  "IRS") that I am subject to backup  withholding  as a result of failure to
report all  interest or  dividends,  or (c) the IRS has notified me that I am no
longer subject to backup withholding, and

(3) I am a U.S. person (including a U.S. resident alien).


Certificate  Instructions -- You must cross out item (2) above, if you have been
notified by the IRS that you are subject to backup withholding  because of under
reporting  interest or  dividends  on your tax return.  However,  if after being
notified by the IRS that you were  subject to backup  withholding  you  received
another  notification  from the IRS that you are no  longer  subject  to  backup
withholding,  do not cross out item (2). (Also see  instructions in the enclosed
Guidelines.)

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                          NUMBER ON SUBSTITUTE FORM W-9

Obtaining a Number
If you do not have a  taxpayer  identification  number  or you do not know  your
number,  obtain  Form  SS-5,   Application  for  a  Social  Security  Card  (for
individuals),  or Form SS-4, Application for Employer Identification Number (for
businesses  and  all  other  entities),  at an  office  of the  Social  Security
Administration or the Internal Revenue Service.

To complete  Substitute Form W-9, if you do not have a tax payer  identification
number, write "Applied For" in the space for the taxpayer  identification number
in Part I sign and date the Form, and give it to the requester.  Generally,  you
will then have 60 days to obtain a taxpayer identification number and furnish it
to the requester. If the requester does not receive your taxpayer identification
number within 60 days, backup  withholding,  if applicable,  will begin and will
continue until you furnish your taxpayer identification number to the requester.

     may be subject to backup  withholding if (i) this interest is $600 or more,
     (ii) the  interest is paid in the course of the  payer's  trade or business
     and (iii) you have not provided your correct taxpayer identification number
     to the payer.

possible erroneous backup  withholding.  FILE THIS FORM WITH THE PAYER,  FURNISH
YOUR TAXPAYER  IDENTIFICATION  NUMBER,  WRITE  "EXEMPT" ON THE FACE OF THE FORM,
SIGN AND DATE THE FORM AND RETURN IT 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
withholding.  For details,  see the regulations  under sections 6041,  6041A(a),
6045, and 6050A.

Privacy Act  Notice.-  Section  6109  requires  most  recipients  of  dividends,
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 your tax return.
Payers must be given the numbers  whether or not recipients are required to file
tax returns. Payers must generally withhold 31% of taxable interest,  dividends,
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 Statements 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.-If you falsify  certifications
or affirmations,  you are subject to criminal  penalties  including fines and/or
imprisonment.
