July 24, 2001

TO THE LIMITED PARTNERS OF
MAXUS REAL PROPERTY INVESTORS - FOUR, L.P.

I have received the latest letter from the General Partner of Maxus Real
Property Investors - Four, L.P. dated July 19, 2001. The General Partner has
continued to expend Partnership funds to vigorously attack my tender offer.
The General Partner is clearly concerned by my offer which has led to a
sudden declaration of a $10 per unit quarterly distribution and a new-found
helpfulness in pointing out the deficiencies of my offer. The General
Partner has even gone to the trouble of locating a alleged third-party buyer
for our limited partnership units at prices "in excess of $400."

I am very pleased that my offer has had such a beneficial effect on the
General Partner's treatment of us as limited partners. Up until the recent
declaration of the $10 distribution in the middle of June, the General
Partner had not seen fit to pay distributions to us; in fact, the General
Partner's stated strategy was to stockpile funds in the Partnership so that
it could repurchase units at significantly discounted prices thereby
solidifying its control of the Partnership. In addition, just last month,
the General Partner sent me a letter (but only after the 1,356 units
tendered in the $300 per unit self-tender were purchased) stating that it
was not authorized under the partnership agreement to act on my $400 per
unit offer or even communicate the offer to you. The General Partner's tune
has certainly changed in the last few weeks, even to the extent of providing
a name and toll-free number of the purported interested buyer.

Now, the General Partner motivated by its recently discovered concern for us
as limited partners wants to guide us through the "confusion" created by my
"contingent" offer. Let me save us all the time and trouble in analyzing
this issue. With this letter and my concurrent filing with the Securities
and Exchange Commission, I am waiving absolutely and irrevocably the
condition requiring the tender of a minimum number of units that would
result in my holding a majority of the outstanding units upon completion of
my tender offer. As a result, I will purchase at a price of $400 per unit in
cash any and all units that are tendered and not withdrawn as of the
expiration of the offer at 12:00 Midnight, Central Daylight Time, on
Tuesday, August 7, 2001.

I am extremely comfortable in waiving this condition now because, regardless
of how the General Partner has characterized my offer, it was never
contingent. The condition is a standard one for public company tender offers
where a change of control is the intent of the offeror. I was only
fashioning the offer to make my intentions crystal clear.

I will buy any and all of the units that are tendered prior to the
expiration of my offer. I have no problem with taking a non-majority
interest in the Partnership at this time while continuing my efforts to gain
control. For those of you wishing to tender your units, you may do so by
delivering the letter of transmittal and certificates for the tendered units
to LaSalle Bank National Association at 135 South LaSalle Street, Suite
1811, Corporate Trust Operations, Chicago, Illinois 60603. If you need to
contact the depositary about any aspect of the tender offer by phone or
facsimile, the phone number is (800) 246-5761, menu option #2, and the
facsimile number is (312) 904-2584.





As you consider my offer and the General Partner's reaction to it, ask
yourselves, is the General Partner concerned about your economic interests
or its own? While the General Partner recently (and apparently, reluctantly)
declared a quarterly distribution of $10 per unit, it has been paid over
$180,000 per year in property and partnership management fees. Ask
yourselves, how soon after the completion of my tender offer will the
General Partner find an excuse to end the quarterly distribution? How soon
thereafter will the General Partner or its affiliates be purchasing units
for $200 to $300 or, worse yet, be using Partnership funds to redeem units
in another self-tender? It appears to me that the General Partner has no
plans for this Partnership, other than to collect management fees for as
long as it can. If there were any positive plans in the making, we would
certainly have heard about them in the General Partner's frequent
communications of the past few months. Instead, all we hear from the General
Partner are spurious attacks against me and my good faith offer. It is your
decision to tender into my offer or face the uncertain future with a general
partner which has had a history of placing its interest ahead of yours.

Thank you for your time and attention on these important matters.

Respectfully yours

/s/  O. Bruce Mills
