                           UNIVERSAL BRIDGE FUND, INC.
                          NOTES TO FINANCIAL STATEMENTS

1.       BASIS OF PREPARATION.

         The accompanying financial statements as of June 30, 1999 are
unaudited; however, in the opinion of the management of Universal Bridge Fund,
Inc, a Delaware corporation (the "Company"), such statements include all
adjustments (consisting of normal recurring accruals) necessary to present a
fair statement of the information presented therein.

         Pursuant to accounting requirements of the Securities and Exchange
Commission ("SEC") applicable to quarterly reports on Form 10-Q, the
accompanying financial statements and these notes do not include all disclosures
required by generally accepted accounting principles for audited consolidated
financial statements. Accordingly, these statements should be read in
conjunction with the most recent audited financial statements included in the
Form 10-K, filed by Walnut Financial Services Inc., a Utah corporation (the
"Parent Company"), for the fiscal year ended December 31, 1998, in which the
financial statements of the Company are consolidated.

         Results of operations for interim periods are not necessarily
indicative of those to be achieved for fiscal years.

         The Company has determined it is required to present its financial
statements in accordance with generally accepted accounting principles and SEC
regulations in the format applicable to investment companies, which generally
means that investments are reported at fair market value rather than cost.

2.       ORGANIZATION.

         The Company is a wholly-owned subsidiary of the Parent Company. The
Parent Company is a closed-end management investment company, which elected on
October 15, 1997 to be regulated as a Business Development Company ("BDC") under
the Investment Company Act of 1940, as amended (the "Investment Company Act").
As a result of the technical nature of the Investment Company Act, the Company
and the Parent Company's other then wholly-owned subsidiaries (collectively, the
"Other Subsidiaries"), Walnut Capital Corp., a Delaware corporation, and Walnut
Funds, Inc., a Delaware corporation, also elected to be regulated as BDCs and
registered as reporting companies under the Securities Exchange Act of 1934, as
amended (the "Securities Exchange Act"). Notwithstanding their registration
under the Securities Exchange Act, the Company and the Other Subsidiaries did
not begin filing the periodic reports and other information required by the
Securities Exchange Act in reliance upon a no-action letter (the "No-Action
Letter") received from the staff of the SEC. In the No-Action Letter, the SEC
staff indicated that it would take no action against the Company and the Other
Subsidiaries for failing to file information required by the Securities Exchange
Act in order to permit the Company, the Parent Company and the Other
Subsidiaries to avoid the significant expense and administrative burden of such
filings while applying to the SEC to permit the Company and the Other
Subsidiaries not to file such reports. The SEC staff's position taken in the
No-Action Letter has expired by its terms and the application of the Company,
the Other Subsidiaries and the Parent Company has not been approved by the SEC.
The Company and the Other Subsidiaries have not asked the SEC staff to renew its
position in the No-Action Letter. Therefore, this Quarterly Report on Form 10-Q
is the first periodic report that the Company has filed under the Exchange Act.

         The Company owns 50% of the outstanding general partnership interests
and approximately 83% of the limited partnership of Universal Partnership, L.P.,
an Illinois limited partnership ("UPLP"), which was established in 1994.

3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.

         NET INCOME (LOSS) PER SHARE. Net income (loss) per share is computed
based on the weighted-average number of shares outstanding for each period.
Common stock equivalents have been considered where they are not anti-dilutive.


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

         The only operating activity of the Company is recording the change in
fair value of its investment in UPLP. Due to the nature of its business, the
Company has not generated any cash flow from investing or financing activities
during the applicable period nor has it been required to utilize any funds.

         Certain statements contained in this Quarterly Report on Form 10-Q
which are not historical facts are forward-looking statements that are subject
to risks and uncertainties that could cause actual results to differ materially
from those set forth in or implied by such forward-looking statements.



RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1999 AND 1998.

         The Company had unrealized depreciation on investments of $65,000 for
the six months ended June 30, 1999, compared to unrealized depreciation on
investments of $203,000 for the six months ended June 30, 1998. The unrealized
depreciation on investments reflects solely the change in value of the Company's
investment in UPLP.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 1999 AND 1998.

         The Company had unrealized depreciation on investments of $50,000 for
the three months ended June 30, 1999, compared to unrealized depreciation on
investments of $130,000 for the three months ended June 30, 1998. The unrealized
depreciation on investments reflects solely the change in value of the Company's
investment in UPLP.

INVESTMENT PORTFOLIO CHANGES.

The Company's equity investments that appreciated/(depreciated) in value during
the six months ended June 30, 1999 were as follows:

                                        Unrealized Appreciation (Depreciation)
                                        --------------------------------------

Universal Partners, L.P.                            $   (65,000)


YEAR 2000 COMPLIANCE.

         The year 2000 creates the potential for date related data to cause
computer processing errors or system shut-downs because computer-controlled
systems have historically used two digits rather than four to define years.
Computer programs that contain time data sensitive software may recognize a date
using two digits of "00" as the year 1900 rather than the year 2000. The
miscalculations and systems failures that may be caused by such date
misrecognition could disrupt the operations of the Company or


<PAGE>   10

its portfolio companies. Since this risk relates to computer-controlled systems,
the year 2000 issue affects computer software, computer hardware, and any other
equipment with imbedded technology that involves date sensitive functions. Since
the Company's only activity is recording the change in value of its investment
in UPLP, which is performed with software and hardware owned by the Parent
Company, the Company will be affected by the Year 2000 issue only if the Parent
Company is not Year 2000 compliant.
