                   BRUNNER COMPANIES INCOME PROPERTIES, L.P. I
                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

The accompanying unaudited financial statements of Brunner Companies Income
Properties L.P. I (the "Partnership") have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-QSB and Item 310(b)of Regulation S-B.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of 104 Management, Inc. (the "Managing General Partner"), an Ohio
corporation, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included. Operating
results for the six month period ended June 30, 1999, are not necessarily
indicative of the results that may be expected for the fiscal year ending
December 31, 1999. For further information, refer to the financial statements
and footnotes thereto included in the Partnership's annual report on Form 10-KSB
for the fiscal year ended December 31, 1998.

Certain reclassifications have been made to the 1998 information to conform to
the 1999 presentation.


Note B - Transactions with Affiliated Parties

The Partnership has no employees and is dependent on the Managing General
Partner and its affiliates for the management and administration of all
partnership activities. All of the outstanding stock of the Managing General
Partner is owned by BCIP I & III, LLC, an affiliate of Hull/Storey Development,
LLC ("Hull/Storey"). The partnership agreement provides for payments to
affiliates for property management services based on a percentage of revenue and
for reimbursement of certain expenses incurred by affiliates on behalf of the
Partnership. The following payments were made to affiliates of the Managing
General Partner during the six months ended June 30, 1999 and 1998 (in
thousands):

                                                                       ----             ----

         Property management fees (included in
                  operating expenses)                                  $39              $45
         Reimbursement for services of affiliates
                  (included in general and administrative
                  expenses)                                            $24              $24
</TABLE>

Additionally, the Partnership paid approximately $20,557 and $24,000 to an
affiliate of the Managing General Partner for lease commissions related to new
leases at the Partnership's properties during the six months ended June 30,1999
and 1998, respectively. These lease commissions are included in other assets and
amortized over the terms of the respective leases.

Note C - Mortgage Notes Payable

Pursuant to lender agreements the maturity dates of the mortgage notes were
extended until May 10, 2000. The agreements further provide that, from and after
October 10, 1998 through May 10, 2000, the mortgage notes accrued interest at a
fixed rate per annum of seven (7%) percent. Prior to the agreements, the stated
interest rate of the mortgage notes was nine (9%) percent. The agreement further
provides that, commencing with the June 1999 payment and continuing monthly
through the May 2000 payment, the Partnership is allowed to pay fixed monthly
payments based upon 7 1/2% per annum of the principal debt. The principal
balance bears interest at the rate of 7% per annum, and the excess payment is a
principal reduction. The agreements further provide that the lender, upon
fifteen (15) days prior written notice to the Managing General Partner, shall
have the right to accelerate repayment of the mortgage notes in full and demand
the Partnership repay the mortgage notes in full, with or without cause and
regardless of whether an event of default should exist or not. The mortgages
require a balloon payment at maturity for the remaining principal balance. These
notes are all cross-collateralized and cross-defaulted. The mortgage notes
payable are nonrecourse and are secured by the properties and by a pledge of
revenues from the respective properties.


The Partnership's continued ability to operate is dependent on its ability to
either restructure its existing debt or raise additional capital. To that end
the Managing General Partner is attempting to extend or modify the mortgage
notes, negotiating alternative financing sources requiring additional capital
infusions and evaluating the Partnership's alternatives. However, there can be
no assurance that debt restructuring will occur or additional capital will be
raised in a manner that allows the Partnership to continue its operations in its
present form.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

The Partnership's investment properties consist of three retail centers. The
following table sets forth the average occupancy of the properties for the six
months ended June 30, 1999, and June 30, 1998:

<TABLE>
<CAPTION>
                                                      Average
                                                     Occupancy
                                              1999               1998
                                              ----               ----
<S>                                           <C>                <C>
Hitchcock Plaza,                               91%                92%
 Aiken, South Carolina

Whitehorse Plaza,                              17%                99%
 Greenville, South Carolina

Georgetown Landing,                           100%                97%
 Georgetown, South Carolina
</TABLE>


All but approximately 20,000 square feet of Hitchcock Plaza has been leased. The
Managing General Partner has executed a new lease for a portion of this space,
and the Managing General Partner is currently negotiating a lease for the
remainder of this space. One of the anchor tenants,


<PAGE>   8



Kroger Company, has performed a major upfit of its space, and likewise, K-Mart
modified its space to a Big-K and reconfigured its current space.

Whitehorse Plaza's anchor tenants have both vacated their respective spaces. One
tenant continues to pay rent pursuant to its lease obligation. The other tenant
maintains that it is entitled to terminate its lease because the other anchor
tenant has vacated the center. The Managing General Partner has instituted a
lawsuit to enforce the lease obligations of the tenant who has ceased paying
rent, and there are currently two separate lawsuits pending regarding this
matter. The Managing General Partner intends to pursue this matter to a
conclusion.

As noted in the Partnership's Form 10-QSB for the quarterly period ended March
31, 1999, the Managing General Partner and the lender holding the debt on the
Partnership properties had entered into an agreement whereby the Partnership was
not obligated to pay the full monthly payment obligation for each property, but
interest only at the rate of 7% annum and certain escrow deposits. The lender
and the Managing General Partner have agreed to a similar arrangement through
and including May 10, 2000. Basically, the Partnership is making fixed monthly
payments which represent interest on the principal debt at the rate of 7% annum,
a moderate principal reduction and an escrow deposit for taxes and insurance.
After payment of a management fee and operating expenses, the net operating
income is deposited into a joint account with the lender and the Partnership. As
of June 30, 1999, $300,320 was deposited into the joint account pursuant to the
agreement.

As part of the ongoing business plan of the Partnership, the Managing General
Partner monitors the rental market environment of each of its investment
properties to access the feasibility of increasing rents, maintaining or
increasing occupancy levels and protecting the Partnership from increases in
expense. As part of this plan, the Managing General Partner attempts to protect
the expenses by increasing rents and maintaining a high overall occupancy level.
However, due to changing market conditions, which can result in the use of
rental concessions and rental reductions to offset softening market conditions,
there is no guarantee that the Managing General Partner will be able to sustain
such a plan.

At June 30, 1999, the Partnership held unrestricted cash of approximately
$998,000 compared to approximately $480,000 at June 30, 1998. The net increase
in cash for the six months ended June 30, 1999, was approximately $518,000
compared to a net increase of approximately $50,000 for the six months ended
June 30, 1998. The net increase in cash is primarily due to the decrease in
interest expense and operating expenses and to the increase in rental income
discussed above as well as to the lack of principal payments.

No cash distributions were made during fiscal year 1998 or during the first six
months of 1999, and future cash distributions will depend on the levels of net
cash generated from operations, refinancing, property sales, and the
availability of cash reserves after restructuring to existing indebtedness.

Year 2000

The "Year 2000 Issue" has arisen because many existing computer programs and
chip-based embedded technology systems use only the last two digits to refer to
a year, and therefore do not


<PAGE>   9



properly recognize a year that begins with "20" instead of the familiar "19". If
not corrected, many computer applications could fail or create erroneous
results. The following disclosure provides information regarding the current
status of the Partnership's Year 2000 compliance program.

The Partnership processes its records on computer hardware and software systems
maintained by Hull/Storey Development, LLC ("Hull/Storey"), the management
company retained by the General Partner of the Partnership. Hull/Storey has
adopted a compliance program because it recognizes the importance of minimizing
the number and seriousness of any disruptions that may occur as a result of the
Year 2000 issue. Hull/Storey compliance program includes an assessment of its
hardware and software computer systems and embedded systems.

Hull/Storey has invested in the implementation and maintenance of accounting and
reporting systems and equipment that are intended to enable the Partnership to
provide adequately for its information and reporting needs and which are also
Year 2000 compliant. Substantially all of Hull/Storey's in-house systems have
already been certified as Year 2000 compliant through testing and other
mechanisms and Hull/Storey has not delayed any systems projects due to the Year
2000 Issue. Hull/Storey is in the process of engaging a third party to review
its Year 2000 in-house compliance. The Managing General Partner believes that
future costs associated with Year 2000 issues for Hull/Storey's in-house systems
will be insignificant and will therefore not impact the Partnership's business,
financial condition and results of operations.
