                WALNUT FINANCIAL SERVICES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       BASIS OF PREPARATION.

         The accompanying consolidated financial statements as of June 30, 1999
are unaudited; however, in the opinion of the management of Walnut Financial
Services, Inc., a Utah corporation (the "Company"), such statements include all
adjustments (consisting of normal recurring accruals) necessary to present a
fair statement of the information presented therein. The balance sheet at
December 31, 1998 was derived from the audited financial statements at such
date.

         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 financial
statements. Accordingly, these statements should be read in conjunction with the
Company's most recent audited financial statements included in its Form 10-K for
the fiscal year ended December 31, 1998.

         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,
including wholly-owed subsidiaries.

2.       ORGANIZATION.

         The 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 such, the Company, among other requirements, is required to
invest at least 70% of its total assets in certain prescribed "Eligible Assets,"
which generally include securities of privately-held companies and cash items,
government securities and high-quality short-term debt. As of June 30, 1999, the
Company had three primary business focuses: (i) investing in start-up and early
stage development companies; (ii) operating an investment vehicle that
specializes in bridge financing to small- to medium-sized companies; and (iii)
providing accounts receivable factoring services to small- and medium-sized
businesses. The Company engages in its investment business through its
wholly-owned subsidiary, Walnut Capital Corp., a Delaware corporation ("Walnut
Capital"), which was formed in 1980 for the purpose of operating as a Small
Business Investment Company (an "SBIC") under the Small Business Investment Act
of 1958 (as amended, the "SBIA") and is subject to regulations promulgated by
the Small Business Administration (the "SBA") pursuant to the provisions of the
SBIA. In the past, the Company also made investments through its wholly-owned
subsidiary, Walnut Funds, Inc., a Delaware corporation ("Walnut Funds"), which
has an ownership interest in and indirectly provides investment management
services to Walnut Growth Partners Limited Partnership, an Illinois limited
partnership ("Walnut Growth"), a $30 million investment fund. Walnut Growth did
not make any investments in 1998, has not made any investments in 1999, and the
Company does not expect Walnut Growth to make any future investments. The
Company pursues its bridge financings through its wholly-owned subsidiary,
Universal Bridge Fund, Inc., a Delaware corporation ("Universal Bridge").
Universal Bridge owns 50% of the outstanding general partnership interests and
approximately 83% of the limited partnership interests of Universal Partners,
L.P., an Illinois limited partnership ("UPLP"), which was established in 1994.

The Company engages in its accounts receivable factoring service business
through its two wholly-owned subsidiaries; Pacific Financial Services Corp., a
Washington corporation ("Pacific Financial"), which was acquired in January
1998, and Inland Financial Corp., a Washington corporation ("Inland Financial")
which was acquired in October 1998. The Company engaged in the human resources
and quality assurance consulting business through its wholly-owned subsidiary,
Walnut Consulting, Inc., a Delaware corporation ("Walnut Consulting"), during
1997 and 1998. The operations of Walnut Consulting were not significant to the
revenues of the Company. As a result of the technical nature of the Investment
Company Act, the Company's wholly-owned subsidiaries, Walnut Capital, Walnut
Funds and Universal Bridge, also have each elected to be regulated as a BDC. On
September 28, 1997, the Company sold all of the outstanding stock of its
wholly-owned subsidiary, NFS Services, Inc., a Delaware corporation ("NFS"),
which performed consulting and asset recovery services.

         On October 27, 1997, the Company initiated a private placement to
accredited investors (the "1997 Private Placement") of a minimum of 50, and a
maximum of 80, units (the "Units") at $50,000 per Unit. Each Unit consisted of
8,333 shares of Common Stock and 5,833 Class A Redeemable Common Stock purchase
warrants (a "Class A Warrant" and collectively, the "Class A Warrants").
Pursuant to the 1997 Private Placement, the Company issued 666,667 shares of
Common Stock and 466,667 Class A Warrants for gross proceeds of $4,000,000. The
Company used a portion of the proceeds of the 1997 Private Placement to acquire
all of the issued and outstanding capital stock of Pacific Financial Services
Corporation. Also on December 18, 1997, the Company consummated the sale of an
additional 166,667 Class A Warrants to certain investors for $100,000.

         On January 28, 1998, the Company acquired all the outstanding common
stock of Pacific Financial for $3,000,000 consisting of $1,500,000 in cash,
39,022 shares of the Company's common stock valued at $300,000, $300,000 in
short term notes and $900,000 in notes payable January 2, 2002. The $300,000
short-term notes were paid at the Pacific closing in accordance with the terms
of the acquisition agreement. The remaining notes are guaranteed by the Company
and bear interest at 8%. Pacific is in the business of accounts receivable
factoring in the Northwest United States.

         On October 19, 1998, the Company acquired Inland Financial through the
merger of a newly formed, wholly owned subsidiary of the Company with and into
Inland Financial with Inland Financial continuing after such merger as the
surviving corporation. Upon consummation of the merger, the Company received all
the outstanding shares of capital stock of the surviving corporation and the
former shareholders of Inland Financial received in the aggregate $650,000 in
cash, 153,393 shares of the Company's common stock valued at $650,000, and
$150,000 in short term notes. The short-term notes are guaranteed by the Company
and bear interest at 8% per annum. Such shareholders are eligible to receive
additional payments of cash, notes and stock of the Company valued at up to
$950,000, based on the net income performance of Inland through April 2000.
Inland is in the business of accounts receivable factoring in the Northwest
United States.

         On January 22, 1999, the Company effected a one-for-six reverse stock
split (the "Reverse Stock Split") of its Common Stock, pursuant to shareholder
approval granted at the annual meeting of the shareholders of the Company held
on January 20, 1999. Fractional shares held by any holder of Common Stock after
aggregating all of such holder's shares were rounded up to the nearest whole
share. Immediately following the effectiveness of the Reverse Stock Split, after
giving effect to the rounding up of fractional shares, there were 3,350,533
issued and outstanding shares of Common Stock. All share amounts, price and
other material terms described herein for the Common Stock and options and
warrants exercisable therefor give effect to the Reverse Stock Split regardless
of the date with respect to which such share amounts, price or other terms are
being described.

3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.

         PRINCIPLES OF CONSOLIDATION. The financial statements of the Company
include the accounts of the Company, Walnut Funds, Walnut Consulting and
Universal Bridge. Investments in Pacific Financial and Inland Financial are
recorded at costs which approximate fair market value. Intercompany transactions
and balances have been eliminated in consolidation.

         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.
All share and per share amounts have been retroactively adjusted to account for
the Reverse Stock Split.

4.       RELATED PARTY TRANSACTIONS.

         The Company and its subsidiaries retain a law firm at which a Company
officer is of counsel. Payments of $82,000 were paid to such firm by the Company
during the six months ended June 30, 1999 for reimbursement of expenses and
legal services incurred. Such expenses and fees were incurred in connection with
normal business activities and costs associated with the Annual Meeting Proxy
Statement and the Reverse Stock Split.

         In April 1997, the Company received an unsecured loan from a related
party in the amount of $400,000. Such loan bears interest at 9.5% per annum. The
loan was to be repaid in four quarterly installments commencing March 31, 1998.
The first and second installments were paid on April 1, 1998 and July 1998,
respectively. The third and forth payments which were due on October 1, 1998 and
January 1, 1999 respectively have been deferred and the Company is allowed to
defer further principal payments provided that quarterly interest is paid on the
outstanding balance.

         In connection with the transaction through which the Company acquired
Inland Financial, Inland Financial borrowed $293,000 from two related parties.
The Company issued to each entity a promissory note, which matures on October
19, 1999. The promissory notes bear interest at a rate of 16% per year payable
quarterly.


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


         As previously indicated, the Company reports the results of its
operations as an investment company rather than as an operating company. Because
of such reporting, the Company's consolidated financial statements include the
operating results only of the Company, Walnut Capital and Universal Bridge. For
all subsidiaries other than Walnut Capital and Universal Bridge, the Company
reports only the fair value of its investments therein as of the date of such
information. The only operating activity of Universal Bridge is recording the
change in fair value of its investment in UPLP.


         The Company separately discusses and analyzes the results of operations
and the liquidity and capital resources of the Company (excluding Walnut
Capital) and Walnut Capital. The Company is required by regulations promulgated
by the SBA to separately present such information for Walnut Capital in its
Annual Reports on Form 10-K and is utilizing the same reporting format in this
Quarterly Report on Form 10-Q. The results of operations of the Company
(excluding Walnut Capital) and Walnut Capital for a particular period in the
aggregate represent the consolidated results of operations of the


<PAGE>   11


Company for such period before adjustments to reflect intercompany transfers and
other adjustments all made in accordance with generally accepted accounting
principles.

         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. These
risks and uncertainties include the Company's entry into new commercial
businesses, the risk of obtaining financing, and other risks described in the
Company's filings with the SEC.

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

         Results of Walnut Capital's Operations for the Six Months Ended June
30, 1999 and 1998. Walnut Capital had realized gain income of $4,022,000 for the
six months ended June 30, 1999, compared to $1,126,000 for the six months ended
June 30, 1998. The realized gains for the six months ended June 30, 1999
resulted predominately from the sale of shares of First Health Group, Inc.
(formerly HealthCare COMPARE Corp.) and Multimedia Games, Inc.

         Interest expense for the six months ended June 30, 1999 was $101,000 as
compared to $209,000 for the same period in 1998. The decrease of $108,000 or
52% in interest expense is attributable to a repayment of $2,000,000 of
debentures to the SBA (the "Walnut Debentures") on June 1, 1998, and a reduction
in margin payable to brokers. General and administrative expenses for the six
months ended June 30, 1999 was $336,000 as compared to $325,000 for the six
months ended June 30, 1998.

         Unrealized depreciation on investments before income tax for the six
months ended June 30, 1999 was $3,715,000 as compared to $1,442,000 for the same
period in 1998. The difference of $2,273,000 in unrealized depreciation is
primarily the result of the recognition for the six months ended June 30, 1999
of amounts previously recorded as unrealized gains on investments before income
tax attributable to First Health Group, Inc.
securities.

         Results of the Operations of the Company (excluding Walnut Capital) for
the Six Months Ended June 30, 1999 and 1998. The Company had interest income of
$60,000 and general and administrative costs of $407,000 for the six months
ended June 30, 1999 as compared to $35,000 and $468,000, respectively, for the
six months ended June 30, 1998. The $61,000 decrease in general and
administrative costs is due to the payment of less directors' fees and legal
fees. For the six months ended June 30, 1999, the unrealized depreciation
attributable to the Company's wholly-owned subsidiary, Universal Bridge and its
majority owned subsidiary, UPLP, was $65,000.

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

         Results of Walnut Capital's Operations for the Three Months Ended June
30, 1999 and 1998. Walnut Capital had realized gain income of $2,000 for the
three months ended June 30, 1999, compared to $172,000 for the three months
ended June 30, 1998. The realized gains for the three months ended June 30, 1999
resulted predominately from the sale of shares of Multimedia Games, Inc.

         Interest expense for the three months ended June 30, 1999 was $49,000
as compared to $88,000 for the same period in 1998. The decrease of $39,000 or
44% in interest expense is attributable to a repayment of $2,000,000 of the
Walnut Debentures on June 1, 1998, and a reduction in margin payable to brokers.
General and administrative expenses for the three months ended June 30, 1999 was
$179,000 as compared to $170,000 for the three months ended June 30, 1998.


<PAGE>   12


         Unrealized appreciation on investments before income tax for the three
months ended June 30, 1999 was $267,000 as compared to $628,000 unrealized
depreciation on investments for the same period in 1998. The difference of
$895,000 in unrealized appreciation is primarily the result of the appreciation
in value of I-Flow Corp.'s stock in 1999 and the depreciation in value of
Paragon Health and I-Flow stock in 1998.

         Results of the Operations of the Company (excluding Walnut Capital) for
the Three Months Ended June 30, 1999 and 1998. The Company had interest income
of $19,000 and general and administrative costs of $211,000 for the three months
ended June 30, 1999 as compared to $16,000 and $257,000, respectively, for the
three months ended June 30, 1998. The $46,000 decrease in general and
administrative costs is due to a decrease in legal fees. For the three months
ended June 30, 1999, the unrealized depreciation attributable to the Company's
wholly-owned subsidiary, Universal Bridge and its majority owned subsidiary,
UPLP, was $50,000.

LIQUIDITY AND CAPITAL RESOURCES.

         Liquidity and Capital Resources of Walnut Capital. As part of the SBIC
program, Walnut Capital has, from time to time, issued $12 million of Walnut
Debentures, of which Walnut Debentures in the principal amount of $8 million
were repaid prior to 1998. Additional Walnut Debentures in the principal amount
of $2 million was repaid on June 1, 1998. Walnut Debentures in the principal
amount of $2 million were outstanding as of June 30, 1999. Such Walnut
Debentures were originally issued in September 1989, bear interest at a rate of
8.80% per annum and are due on September 1, 1999.

         Interest on the Walnut Debentures is paid semi-annually, and principal
is due at maturity. Walnut Capital has been current in all of its interest
payments to the SBA.

         The Walnut Debentures prohibit the distribution of earnings or other
assets of Walnut Capital to the Company, except for distributions made out of
undistributed realized earnings computed in accordance with SBA regulations. For
so long as any indebtedness under the Walnut Debentures remains outstanding,
Walnut Capital is prohibited from repurchasing or converting any of its equity
(but not debt) securities or paying dividends (including dividends to the
Company) without the consent of the SBA. In addition, Walnut Capital is
prohibited from incurring any secured indebtedness, except for the $5,765,000 of
secured indebtedness that was outstanding at April 8, 1994. There are no
limitations on the amount of unsecured indebtedness Walnut Capital can incur.
The Walnut Debentures cannot be prepaid without payment of a prepayment penalty
related to the time of such prepayment.

         Additionally, Walnut Capital reduced its broker margin account by $1.7
million and increased its cash and cash equivalents by $1.4 million in the first
quarter of 1999. The source of funds were primarily from the sale of First
Health Group, Inc. (formerly HealthCare COMPARE Corp.) securities, creating a
realized capital gain of approximately $4 million in the first quarter of 1999.
Walnut Capital has cash and a broker margin account available to repay the $2
million of Walnut Debentures due September 1, 1999.

         In 1998, the SBA issued a finding that Walnut Capital the Company had
violated Section 107.700, by purchasing securities from a big business as
defined in the SBA regulations. The Company believes the SBA is in error in its
interpretation of this finding, by including shares held by employees of the
seller as being affiliated with such seller. The SBA has also informed Walnut
Capital that it is in violation of section 107.503(c) and 107.650 and valuation
guidelines for SBICs. The Company disagrees with the SBA's interpretation of the
requirements and the matter is being discussed with the SBA. The SBA also found
Walnut Capital in violation of Section 107.825(e), purchase of securities from
non-issuers. The Company believes this finding to be inconsistent with actions
taken by the SBA in the past,

and has entered into discussions with the SBA to clarify the issue. The SBA, if
it finally determines that Walnut Capital did violate any of the foregoing
regulations, may declare a default under the outstanding $2,000,000 of Walnut
Debentures and accelerate the maturity for such Walnut Debentures from September
1, 1999 to the date of such acceleration. Further, Walnut Capital has not filed
its Form 468 for the year ended December 31, 1998. This report was due on March
31, 1999. Management believes that none of these findings will have material
effect on Walnut Capital, or the Company as a whole, and believes that if the
maturity of the Walnut Debentures is accelerated, it will have sufficient funds
available from existing sources of liquidity to satisfy its repayment
obligations.

         In April 1997, Walnut Capital received an unsecured loan from The
Holding Company ("THC"), a company for which Burton W. Kanter, a director of the
Company, serves as President, in the amount of $400,000. The loan bears interest
at 9.5%. The loan was to be repaid in four installments each following the end
of each of the fiscal quarters of the Company in 1998 with the first installment
to be paid on April 1, 1998. The first and second installments were paid on
April 1, 1998 and July 1998, respectively. The third and fourth payment which
were due on October 1, 1998 and January 1, 1999 had been deferred and the
Company is allowed to delay further principal payments provided that quarterly
interest to be paid on the outstanding balance. The Company has been current in
all of its interest payment to THC, and this loan has a principal balance of
$200,000 as of June 30, 1999.

         Liquidity and Capital Resources of the Company (excluding Walnut
Capital). On August 31, 1995, the Company established a $4 million line of
credit with American National Bank and Trust Company of Chicago ("ANB"). This
line was replaced as of September 8, 1996 with a term loan of $2,850,000. A
principal payment of $575,000 was made on March 31, 1997 and the balance was due
on July 31, 1997. This loan was renewed and amended to provide quarterly
principal payments of $250,000 commencing on December 31, 1997 with a maturity
date of June 30, 1999. On December 31, 1998, this bank loan was further amended
to require an immediate principal payment of $100,000 and quarterly principal
payments thereafter and it has an amended maturity date of December 31, 1999.
Following the principal payment required on such date, the loan had a principal
balance of $825,000 on June 30, 1999. The interest rate associated with this
loan is ANB's base rate plus 2% (10.5% as of June 30, 1999). Two Directors of
the Company personally guarantee the loan.

         In connection with the transaction through which the Company acquired
Inland Financial, Inland Finnacial borrowed $250,000 from the Kanter Family
Foundation, an entity affiliated with the Company, and $43,000 from Windy City,
Inc., an entity affiliated with the Company, in October 1998. The Company issued
to each entity a promissory note, which matures on October 19, 1999. The
promissory notes bear interest at a rate of 16% per year, which is payable
quarterly. These loans are unsecured.

         The Company guarantees the indebtedness of each of Pacific Financial
and Inland Financial under their respective revolving lines of credit. Subject
to certain conditions, Inland Financial is permitted to borrow up to $2,500,000
under its credit facility and Pacific Financial is permitted to borrow up to
$1,000,000 under its credit facility. The Company's guarantee of each facility
is a guarantee of payment and not a guarantee of collection.

         The Company has paid no cash dividends since its inception and it is
unlikely that any cash dividend will be paid in the future. The declaration in
the future of any cash or stock dividends will be at the discretion of the
Company's Board of Directors depending upon the earnings, capital requirements
and financial position of the Company, general economic conditions and other
pertinent factors. Unless otherwise approved by the SBA, Walnut Capital is
prohibited from making any dividend or other cash advance to the Company. Inland
Financial is prohibited from making any dividends to the Company without the
consent of Inland Financial's lender under the terms of a revolving credit
facility.

         There were unrealized losses of ($65,000) recorded in connection with
Universal Bridge's partnership interest in UPLP.

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 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.

         The Company has assessed the scope of its Year 2000 problems and
remediated such problems for each of its internal computer software programs and
its computer hardware. The Company spent no amounts to modify or replace its
internal computer software program and its computer hardware, including to
upgrade software and to modify maintenance agreements in the quarter ended June
30, 1999. Through June 30, 1999, it has spent $15,000 in aggregate for such
upgrades and modifications.


<PAGE>   15


The Company does not believe that it has machinery with embedded computer
technology or that it relies upon any supplier that is material to its business.
Since it believes its assessment and remediation efforts have been completed,
the Company has not developed any contingency plans in the event it or any of
its subsidiaries experiences year 2000 problems and it does not expect to expend
any material amounts on such remediation in the future. However, if the Company
has failed to properly assess any of the year 2000 problems or failed to fully
remedy any identified year 2000 problems of its computer hardware or computer
software programs, the Company may be forced to spend more on such remediation
in the future and the Company's operations may be adversely affected.

         Since the Company does not control its portfolio companies (other than
wholly-owned subsidiaries which are accounted for as portfolio companies because
the Company reports its financial results as an investment company), it has not
attempted to dictate assessment, remediation or contingency planning for such
companies, though Company representatives on the boards of directors of
portfolio companies have participated in such boards' oversight of those
companies' year 2000 efforts. Each portfolio company's year 2000 efforts are
necessarily directed by such companies' management and boards of directors.
Furthermore, the Company has invested in many private companies which are not
obligated to inform the Company about their year 2000 efforts. If any portfolio
company fails to timely assess or remediate its year 2000 problems, the value of
the Company's investment in such portfolio company may be adversely impacted.
The aggregate value of Company's portfolio could be materially adversely
impacted if a number of portfolio companies experience year 2000 problems or
significant costs to avoid or remediate such problems. The Company does not
expect to know the impact of the year 2000 problem on the aggregate value of its
portfolio until after January 1, 2000. None of the Company's computer systems
are interrelated with those of any of its portfolio companies.
