                           FORWARD LOOKING STATEMENTS

         This Report contains forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended and Section 27A
of the Securities Act of 1933, as amended. When used in this Report, the words
"may," "will," "expect," "anticipate," "continue," "estimate," "project" or
"intend" and similar expressions identify forward-looking statements regarding
events, conditions and financial trends in connection with our future plan of
operations, business strategy, operating results and financial position.
Discussions containing such forward-looking statements may be found in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations under the captions "Comparison of Six Months Ended June 30, 2000 and
June 30, 1999," and "Liquidity and Capital Resources," below. Current
shareholders and prospective investors are cautioned that any forward-looking
statements are not guarantees of future performance. Such forward-looking
statements by their nature involve substantial risks and uncertainties, certain
of which are beyond the Company's control, and actual results for future periods
could differ materially from those discussed in this Report, depending on a
variety of important factors, among which are the success or failure of
management's efforts to implement its business strategy; the level of
acquisition opportunities available to the Company and the Company's ability to
price and negotiate such transactions on a favorable basis; the Company's
ability to properly manage growth and successfully integrate acquired companies
and operations; the Company's ability to compete with major established
companies; the Company's ability to attract and retain qualified personnel, and
other risks which are described in the Company's Form 10-SB, as amended, and as
may be described from time to time in the Company's other filings with the SEC.

ITEM 1.  FINANCIAL STATEMENTS

Board of Directors and Shareholders
Summit Brokerage Services, Inc. and Subsidiaries
Indialantic, Florida

We have reviewed the consolidated statements of financial condition of Summit
Brokerage Services, Inc. and Subsidiaries as of June 30, 2000 and the related
consolidated statements of income (loss) for the six months and three months
ended June 30, 2000, and the consolidated statement of cash flows for the six
months ended June 30, 2000. These financial statements are the responsibility of
the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the aforementioned financial statements for them to be in conformity
with generally accepted accounting principles.

                SUMMIT BROKERAGE SERVICES, INC. AND SUBSIDIARIES

                          NOTES TO FINANCIAL STATEMENTS

NOTE 1 - GENERAL

The consolidated financial statements for the six months and three months ended
June 30, 2000 reflect all adjustments (consisting only of normal recurring
adjustment) which are, in the opinion of management, necessary for a fair
presentation of the financial position and operating results for the interim
period. The consolidated financial statements should be read in conjunction with
the consolidated financial statements and notes thereto, together with
management's discussion and analysis of financial condition and results of
operations, contained in the Company's Annual Report on Form 10-SB for the
fiscal year ended December 31, 1999. The results of operations for the six and
three months ended June 30, 2000 are not necessarily indicative of the results
for the entire fiscal year ending December 31, 2000.

NOTE 2 - LIABILITIES SUBORDINATED TO CLAIMS OF GENERAL CREDITORS

On March 31, 2000, the Company entered into a secured demand note collateral
agreement with a corporation 100% owned by Summit's majority shareholder. The
note is due on April 30, 2001 and accrues interest at 12.0% per annum. The
subordinated borrowing is available in computing net capital under the SEC's
uniform net capital rule. To the extent that such borrowings are required for
the Company's continued compliance with minimum net capital requirements, it may
not be repaid.

NOTE 3 - RELATED PARTY TRANSACTION

During the quarter ended June 30, 2000, the Company purchased fixed assets with
a net book value of $69,582 from a company owned by the majority stockholder of
the Company. Payment for these assets was made by reducing $51,280 of a
receivable due from the related party and assuming an $18,302 capital lease
obligation on the acquired assets.

NOTE 4 - STOCK OPTIONS

On May 16, 2000, the Company cancelled all previously issued and outstanding
options to purchase the Company's common stock, none of which had been
exercised. In replacement thereof, the Company granted stock options to its
officers, directors and certain employees to purchase an aggregate of 1,037,878
shares of common stock at an exercise price of $2.50 per share. The exercise
price is not less than 85% of the market price, therefore, under APB Number 25,
the stock option plan is not considered to be compensatory. Accordingly, no
compensation expense has been recognized in the financial statements.

NOTE 5 - COMMITMENTS AND CONTINGENCY

On May 16, 2000, the two-year employment agreement with William R. Turner (the
"Turner Employment Agreement") was amended. Mr. Turner will, effective January
1, 2000 through the remaining term of the original agreement, forego his rights
to receive 15,000 shares of company stock per year and his rights to receive
100,000 options (50,000 options each year of the term). In lieu of these items,
the Company granted to Mr. Turner on May 16, 2000, 160,000 options of the
company's common stock exercisable at $2.50 per share. All other terms and
conditions of the agreement remain the same. Effective August 16, 2000, Mr.
Turner tendered his resignation to the Company for personal reasons and he will
retain 80,000 options of 160,000 options granted pursuant to his employment
agreement.

On May 16, 2000, the Company entered into employment agreements with Mr. Richard
Parker, (the "Parker Employment Agreement"), the Company's Chairman and CEO and
Mr. Mark F. Caulfield (the "Caulfield Employment Agreement"), the Company's
Chief Financial Officer. Both agreements commenced on January 1, 1998 and will
expire December 31, 2001. The Parker Agreement provides that in consideration
for Mr. Parker's services, he is to be paid a salary of $155,000 in year 2000
and his salary will be increased by $5,000 per year each year thereafter. Also
on May 16, 2000, Mr. Parker was granted 320,000 common stock options. Options
will be granted each year thereafter at a rate of 100,000 shares annually. The
Caulfield Employment Agreement provides that in consideration for Mr.
Caulfield's services, he is to be paid a salary of $60,000. This salary will be
increased $5,000 per year each year thereafter. Mr. Caulfield also was granted
on May 16, 2000 160,000 common stock options. Options will be granted each year
thereafter at a rate of 50,000 shares annually. The exercise price under both
employment agreements is $2.50 per share.

No compensation has been recorded under APB 25, for the shares received since
the exercise price is not less than 85% of the market price on the date granted.
These options have been included in Note 4.

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

The following discussion and analysis of the Company's financial condition and
results of its operations for the six month periods ended June 30, 2000 and
1999, should be read in conjunction with the Company's financial statements
included elsewhere herein. When used in the following discussions, the words
"believes," "anticipates," "intends," "expects," and similar expressions are
intended to identify forward-looking statements. Such statements are subject to
certain risks and uncertainties, which could cause results to differ materially
from those projected.

RESULTS OF OPERATIONS

COMPARISON OF SIX MONTHS ENDED JUNE 30, 2000 AND JUNE 30, 1999

            Revenues. Revenues for the six months ended June 30, 2000 rose to
$4,401,432, an increase of $2,455,275 or 126% over the six months ended June 30,
1999. This change was due to the increase in new branch offices from 1999 to
2000 (from 32 to 51,) higher revenues from existing offices (those added prior
to 2000,) and the increase in new offices that employ higher producing
registered representatives.

            Expenses. Expenses for the six months ended June 30, 2000 increased
by $2,106,403 or 93% to $4,368,207 from $2,261,804 for the six months ended June
30, 1999. The higher expenses were largely attributable to the related direct
costs of the increased revenues - commissions expense (the payments to the
registered representatives for their portion of the revenue). Such commission
expenses were $3,400,225 for the six months ended June 30, 2000 compared with
$1,354,893 for the comparable period in 1999. The Company also incurred higher
non-cash expenses for amortization of unearned stock compensation in the amount
of $205,996 for the six months ended June 30, 2000, compared with $84,960 for
the comparable period in 1999.

            Management fees expense as a category was eliminated on January 1,
2000 due to the termination of the agreement with the former management company,
Summit Group of Companies, Inc., effective January 1, 2000. The services were
replaced internally by the Company, and the expenses are now reflected in
various general and administrative categories, such as salaries and wages. In
the six months ended June 30, 1999, total management fees expense was $538,933.

            Net Income. Net income for the six months ended June 30, 2000 was
$33,225, an increase of $348,872 or 111% from a loss of ($315,647) during the
six months ended June 30, 1999. Net income for the six months ended June 30,
2000 was .75% of revenues compared to a net loss of (16.2%) for the six months
ended June 30, 1999. The increase in income from operations overall resulted
primarily from increased revenues and gross profits. The Company's basic
earnings per share were $0.0073 for the six months ended June 30, 2000 compared
to a per share loss of ($0.0794) for the six months ended June 30, 1999. The
Company's diluted earnings per share were $0.0072 for the six months ended June
30, 2000 compared to a per share loss of ($0.0794) for the six months ended June
30, 1999.

LIQUIDITY AND CAPITAL RESOURCES

            Net cash used in operating activities totaled $140,865 during the
six months ended June 30, 2000, compared to net cash used of $270,773 for the
comparable period in 1999. The decrease in cash used by operating activities is
due to the Company's overall increase in revenue from its operations.

           Cash used in investing activities (capital expenditures) totaled
$25,578 and $8,095 during the six months ended June 30, 2000 and 1999,
respectively. During 2000 and 1999, capital expenditures were primarily
comprised of the Company's investments in securities and replacement of office
computer equipment.


                                       10
<PAGE>   12

            Net cash provided by financing activities during the six months
ended June 30, 1999 totaled $201,000 from the issuance of common stock through a
limited private placement. No such issuance occurred during the six months ended
June 30, 2000.

            On March 31, 2000 the Company entered into a secured demand note
collateral agreement with a corporation 100% owned by the Company's majority
shareholder. The note is due on April 30, 2001 and accrues interest at 12% per
annum. The subordinated borrowing is available in computing net capital under
the SEC's uniform net capital rule. To the extent that such borrowings are
required for the Company's continued compliance with minimum net capital
requirements, it may not be repaid.

            The Company anticipates, based on its currently proposed plans and
assumptions relating to its operations, that the Company's existing working
capital and anticipated cash flows from the Company's operations will be
sufficient to satisfy the Company's cash requirements for at least twelve
months. As the Company continues to grow, additional equity and/or debt
offerings may be considered, in part or in combination, as the situation
warrants. In the normal course of business, the Company evaluates acquisitions
of businesses that compliment the Company's business. In connection with any
acquisitions, the Company may issue additional securities, which could result in
dilution for existing shareholders. In addition, in the event the Company's
plans change or its assumptions change or prove to be inaccurate, or if
projected cash flow otherwise proves insufficient to fund operations, the
Company might need to seek other sources of financing to conduct its operations.
There can be no assurance that any such other sources of financing would be
available when needed, on commercially reasonable terms, or at all.

            Inflation. Inflation has not been a major factor in the Company's
business since inception. There can be no assurances that this will continue if
and when the Company completes an acquisition or merger.
