              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND BASIS OF PRESENTATION

    Wit Capital Group, Inc. ("WCG" or the "Company") was incorporated on
March 27, 1996 and commenced operations in September 1997. The accompanying
unaudited consolidated financial statements include the accounts of WCG and its
wholly owned subsidiaries, Wit SoundView Corporation ("WSV", formerly SoundView
Technology Group, Inc.), Wit Capital Corporation ("WCC"), SoundView Asset
Management, Inc., SoundView Capital Management, Inc., BidPlus Corporation
("BidPlus") and Wit VC LLC. All material intercompany balances and transactions
have been eliminated in consolidation.

    These financial statements have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission (the "SEC") and, in the
opinion of management, reflect all adjustments necessary for a fair presentation
of the results for the periods presented in conformity with accounting
principles generally accepted in the United States. These financial statements
should be read in conjunction with the Company's audited financial statements
included in the Company's Annual Report on Form 10-K filed with the SEC on
March 30, 2000. Results of the interim periods are not necessarily indicative of
results to be obtained for a full fiscal year.

2. MERGER

    On January 31, 2000, the Company completed its merger with SoundView
Technology Group, Inc., a Connecticut-based private broker-dealer and investment
banking firm focused exclusively on technology. The total consideration was
$320 million consisting of Wit Capital Group, Inc. common stock and cash. The
merger was accounted for using the purchase method of accounting. The excess of
the purchase price over the estimated fair value of the net assets acquired was
allocated to certain identifiable intangible assets and goodwill, a total of
$275.9 million which will be amortized on a straight line basis over periods
between 3 and 20 years. Pro forma results for the three months ended March 31,
2000 are not presented as the merger closed on January 31, 2000, and the pro
forma results for the year ended December 31, 2000 will not be materially
different from the Company's actual results.

3. NET INCOME (LOSS) PER SHARE

    The following table sets forth the calculation of shares used in the
computation of basic and diluted net income (loss) per share

<TABLE>
<CAPTION>
                                                          THREE MONTHS ENDED
                                                              MARCH 31,
                                                        ----------------------
                                                           2000        1999

Shares used in computations:
  Weighted average common shares used in computation
    of basic net income (loss) per share..............  72,997,204   7,266,428
  Dilutive effect of common stock equivalents.........  25,088,551          --
                                                        ----------   ---------
  Weighted average common shares used in computation
    of diluted net income (loss) per share............  98,085,755   7,266,428
                                                        ==========   =========
</TABLE>

    Because the Company reported a net loss in the period ended March 31, 1999,
the calculation of diluted earnings per share in that period does not include
convertible preferred stock, options, warrants and common stock collateralizing
the notes receivable from stockholders, as they are anti-dilutive and would
result in a reduction of net loss per share. If the Company had reported net
income, there would have been an additional 24,991,082 shares as of March 31,
1999 included in the calculation of diluted earnings per share.

4. STOCK OPTION PLAN

    The Company has adopted a stock incentive plan (the "Plan") that permits the
granting of stock options, restricted stock and other awards to employees,
directors and certain consultants of the Company. The exercise price of any
share covered by an option granted to a person owning more than 10% of the
voting power of all classes of stock of WCG cannot be less than 110% of the fair
market value on the day of the grant. The exercise price of any share covered by
an option granted to any person cannot be less than 85% of the fair value on the
day of the grant. Options expire five or ten years from the date of grant, with
the majority of the options expiring in the year 2009.

    As part of the Company's merger with SoundView, on January 31, 2000, the
Company adopted SoundView's Stock Option Plan, although no additional options to
purchase common stock will be granted under SoundView's plan.

    As permitted by Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," ("SFAS No. 123") WCG has accounted
for options granted to employees using the intrinsic value method prescribed by
Accounting Practice Bulletin ("APB") Opinion No. 25, "Accounting for Stock
Issued to Employees." WCG has granted options with exercise prices that are
equal to or greater than management's estimate of the fair value of such common
stock at the date of grant, and accordingly, the Company has recorded no related
compensation expense. For restricted stock issued with future service
requirements, compensation expense is recognized over the relevant vesting
period.

    As of March 31, 2000, the Company has 18,007,174 outstanding options with a
range of exercise prices between $0.35 and $34.88 per share and a weighted
average exercise price of $4.63.

5. WARRANTS

    The Company has 5,796,405 outstanding warrants as of March 31, 2000 with a
range of exercise prices between $1.43 and $5.57. These warrants are exercisable
for 159,110 shares of common stock and 5,637,295 shares of Class B common stock.

6. INVESTMENTS

    In connection with the Company's investment in Wit Capital Europe, the
Company acquired 189,748 shares of enba plc, the Company's joint venture
partner, in exchange for 1,878,596 shares of the Company's common stock. In
addition, the Company holds investments in publicly traded and privately held
companies, venture capital and hedge funds and in limited liability companies.
The Company's investments are primarily accounted for at fair value.

7. CONTINGENCIES

    The Company is currently subject to claims and legal proceedings arising in
the normal course of its business. In the opinion of management, the resolution
of such legal proceedings should not have a material adverse effect on the
financial position, results of operations or liquidity of the Company.

    A person formerly associated with the Company has asserted a right to
purchase 560,000 shares of common stock at $1.43 per share. In the opinion of
management, such assertion is without merit, and the Company intends to contest
any lawsuit filed against it. These 560,000 shares of common stock have been
reported as forfeited stock options in 1998.

8. INCOME TAXES

    The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting For Income Taxes," which requires the recognition of deferred tax
assets and liabilities attributable to differences in the accounting basis and
tax basis of assets and liabilities at tax rates expected to be in effect when
these balances reverse. Future tax benefits attributable to temporary
differences are recognized to the extent that realization of such benefits is
more likely than not. The Company files consolidated Federal and combined state
and local income tax returns with its wholly-owned subsidiaries.

    The components of the Company's income tax expense for the periods ended
March 31, 2000 and March 31, 1999 are as follows:

    The Company's effective tax rate differs from the Federal statutory rate due
to the recording of a valuation allowance on the Company's current period losses
incurred prior to the acquisition of SoundView, nondeductible goodwill related
to the acquisition and state and local income taxes.

    The Company has released its valuation allowance of $16,800,000 recorded
through the date of the SoundView merger as part of purchase accounting for the
merger transaction. The Company has recorded deferred tax assets of $23,000,000
primarily related to net operating loss carryforwards and deferred compensation
offset by deferred tax liabilities resulting from unrealized appreciation on
investments. The Company has also recorded deferred tax liabilities of
$32,000,000 as a result of the difference between the accounting and tax basis
of intangible assets other than goodwill acquired in the merger with SoundView.

9. NET CAPITAL REQUIREMENTS

    WSV and WCC are subject to the SEC's Uniform Net Capital Rule 15c3-1. WSV's
net capital, as defined, is required to be the greater of $250,000 or an amount
determinable based on the market prices and number of securities in which WSV

which was $14,695,624 in excess of the minimum net capital requirement. WCC's
net capital, as defined, is required to be the greater of $100,000 or the
minimum net capital required based on aggregate indebtedness. As of March 31,
2000 and December 31, 1999, WCC's ratio of aggregate indebtedness to net capital
was .53 to 1 and .51 to 1 and its net capital was $14,944,191 and $23,914,930,
which was $14,413,008 and $23,095,740 in excess of the minimum net capital

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

OVERVIEW

    Wit Capital Group, Inc. ("WCG" or the "Company") was incorporated on
March 27, 1996 and commenced operations in September 1997. The accompanying
unaudited consolidated financial statements include the accounts of WCG and its
wholly owned subsidiaries, Wit SoundView Corporation ("WSV", formerly SoundView
Technology Group, Inc.), Wit Capital Corporation ("WCC"), SoundView Asset
Management, Inc., SoundView Capital Management, Inc., BidPlus Corporation
("BidPlus") and Wit VC LLC. Through our broker-dealer subsidiaries, we are the
largest online investment banking group focused exclusively on the Internet and
technology sectors. We offer a strong complement of investment banking services,
from Internet-strategic advisory, venture capital and private equity placements,
to public offerings and M&A advisory. With one of the largest research teams in
the sector, we produce comprehensive sell-side research on over 285 Internet and
technology companies, developed for our online and institutional audiences.

    We are also recognized as the first firm to bring online individual
investors directly into the capital formation process in a meaningful way and
continue to leverage the Internet to revolutionize the way in which issuers and
investors communicate.

    The results presented below for the three month period ended March 31, 2000
reflect the results of the combined company after completion of our merger with
SoundView Technology Group, Inc. ("SoundView") on January 31, 2000. In
March 2000, SoundView changed its name to Wit SoundView Corporation.

    The results presented in the discussion of the three months ended March 31,
1999 reflect the results of Wit Capital Group, Inc. and its broker-dealer
subsidiary, Wit Capital Corporation. During the first three months of 1999, Wit
Capital Corporation was in an early stage of its operations and generated only
minimal revenues from its investment banking and brokerage activities.
Accordingly, the Company does not believe that the period to period comparisons
of its operating results below are necessarily meaningful and should not be
relied upon as indicators of future performance.

MERGER

    On January 31, 2000, the Company completed its merger with SoundView
Technology Group, Inc., a Connecticut-based private broker-dealer and investment
banking firm focused exclusively on technology. The total consideration was
$320 million consisting of Wit Capital Group, Inc. common stock and cash. The
merger was accounted for using the purchase method of accounting. The excess of
the purchase price over the estimated fair value of the net assets acquired was
allocated to certain identifiable intangible assets and goodwill, a total of
$275.9 million which will be amortized on a straight line basis over periods
between 3 and 20 years.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2000 AS COMPARED TO
THE THREE MONTHS ENDED MARCH 31, 1999.

REVENUES

    The Company's revenues for the three months ended March 31, 2000, which
include revenues of SoundView after January 31, 2000, were $106.6 million
compared to $3.9 million for the three months ended March 31, 1999.

    Investment banking revenue for the three months ended March 31, 2000
increased to $60.3 million from $3.1 million for the three months ended
March 31, 1999. Investment banking revenue is primarily derived from the public
offering of equity securities, and also from Internet-strategic advisory,
venture capital and private equity placements, and M&A advisory services. The
growth in investment banking revenue is attributable to favorable issuing
conditions for technology and Internet companies as well as a

                                       10
<PAGE>
larger number of professionals dedicated to our investment banking activities.
During the first quarter of 2000, we participated in a total of 61 public equity
offerings, 31 as co-manager and 30 as syndicate member compared to the three
months ended March 31, 1999 during which we participated in 19 offerings, 8 as
co-manager and 11 as syndicate member. During the first quarter of 2000, we
retained 2.7 million shares for distribution to our online customers, compared
to 1.5 million shares in the first quarter of 1999. In addition to revenue
generated from public equity transactions, revenue related to Internet-strategic
advisory has also increased as a result of an increase number of strategic
advisory relationships and frequency of transactions.

    Brokerage revenue for the three months ended March 31, 2000 increased to
$36.5 million from $434,000 for the three months ended March 31, 1999. Revenues
derived from our brokerage operations are related to our institutional equity
and our online, or individual trading, operations. For the three months ended
March 31, 2000, our institutional and online operations contributed
$32.5 million and $4.0 million, respectively, to our total brokerage revenue.
With the completion of our merger with SoundView, our brokerage services were
expanded to include institutional sales and trading, and accordingly our results
for the three month period ended March 31, 2000 reflect the initial contribution
of that business to our brokerage revenue. For the quarter ended March 31, 2000,
average daily institutional trading commissions rose 31% compared to average
daily commissions recognized by SoundView in the fourth quarter of 1999, prior
to the merger. This revenue has increased as a result of increased trading
volumes, an increase in the number of companies under research coverage and an
increase in the number of stocks for which we make a market. The number of
stocks we make markets in increased to 219 as of March 31, 2000 compared to 181
stocks which SoundView made markets in as of December 31, 1999, prior to the
merger. The increase in revenue derived from our online, or individual trading
business resulted primarily from an increase in the number of active customer
accounts and an increase in the number of trades executed for our online
customers. Wit Capital Corporation charges its online customers a brokerage
commission of $14.95 for market orders and $19.95 for limit orders. The average
daily number of online trades executed for the three month period ended
March 31, 2000 was 3,000, compared to 405 for the three month period ended
March 31, 1999. As of March 31, 2000, total active online accounts numbered
83,100 compared to 2,900 active online accounts as of March 31, 1999.

    Asset management fees for the three months ended March 31, 2000 increased to
$7.8 million from $0 for the three months ended March 31, 1999. This revenue is
derived from management and syndication fees received from our series of
Dawntreader II venture capital funds which closed during the quarter and from
incentive royalties from hedge funds that were formerly managed by SoundView.
During the three months ended March 31, 1999, we had not yet commenced our
venture capital fund operations, and accordingly, derived no revenue from this
business.

    Interest income for the three months ended March 31, 2000 increased to
$1.8 million from $192,000 for the three months ended March 31, 1999. The
Company earns interest income from the investment of cash balances raised
through financing activities until the funds are used in its business. During
the first three months of 2000, the Company's average monthly cash balance was
$136.6 million as compared to a monthly average of $23.8 million for the first
three months of 1999.

    Unrealized gains on investments for the three months ended March 31, 2000
decreased to $62,000 from $155,000 for the three months ended March 31, 1999.
Unrealized gains on investments primarily consist of gains on the mark to market
and sale of equity securities that the Company receives as consideration for
financial advisory services and from increased investment returns from the
Company's investments in investment partnerships focused on the technology
sector.

EXPENSES

    Compensation and benefits expense for the three months ended March 31, 2000
increased to $64.9 million from $6.6 million for the three months ended
March 31, 1999. Compensation and benefits

                                       11
<PAGE>
expense consists of salaries, bonuses and other benefits paid or provided to our
employees. The increase in compensation expense primarily relates to higher
incentive compensation accrued on higher revenues and an increase in the number
of employees from 111 as of March 31, 1999 to 439 as of March 31, 2000.
Compensation and benefits expense as a percentage of total revenues was 61% for
the three months ended March 31, 2000 which represents an improvement from 168%
for the three months ended March 31, 1999. For the three months ended March 31,
1999, compensation expense included $2.6 million related to those portions of
contractual upfront payments to several professionals for which no future
service by the employees was required. As we continue to hire more investment
banking and research professionals and participate in more transactions, we
expect compensation expense to grow.

    Professional services expense for the three months ended March 31, 2000
increased to $2.3 million from $682,000 for the three months ended March 31,
1999. Professional services expense includes legal, consulting, accounting, and
recruiting fees which have increased as we continue to make strategic
investments, expand our business internationally, make improvements to our
customer service and infrastructure, hire additional personnel, and increase our
brokerage and investment banking operations.

    Brokerage and clearance expense for the three months ended March 31, 2000
increased to $6.2 million from $261,000 for the three months ended March 31,
1999. This expense primarily consists of fees paid to independent floor brokers
on the New York Stock Exchange for the execution of institutional customer
agency business as well as amounts paid to our clearing brokers for processing
and clearing customers' trades. The increase in brokerage and clearance expense
reflects the increased transactional volume and growth of our brokerage
operations.

    Data processing and communications expense for the three months ended
March 31, 2000 increased to $1.8 million from $300,000 for the three months
ended March 31, 1999. Data processing and communications expense includes costs
related to market data services, transaction processing and telephone and other
communication charges. These expenses have increased as a result of an increased
number of active customer accounts and an increased volume of transactions
processed. We expect these costs will continue to grow as transaction volume
increases.

    For the three months ended March 31, 2000, we wrote-off approximately
$1.3 million in computer software and hardware originally developed or purchased
to operate an after-hours trading system. In light of information that became
available to us during the quarter regarding redeployment of those assets, we
wrote-off approximately $1.3 million of previously capitalized costs
representing management's estimate of the impairment in the value of the assets.

    Technology development expense for the three months ended March 31, 2000
increased to $1 million from $336,000 for the three months ended March 31, 1999.
This increase resulted from continued enhancements to our technology
infrastructure, primarily related to our online brokerage operations. We expect
technology development expense to increase as operations continue to grow and as
we continue to invest in our infrastructure and new business initiatives.

    Depreciation and amortization for the three months ended March 31, 2000
increased to $1.3 million from $220,000 for the three months ended March 31,
1999. Depreciation and amortization consists primarily of depreciation and
amortization of property, equipment and leasehold improvements and amortization
of computer software. The increases in depreciation and amortization reflect the
increased investments the Company has made in its technology, equipment and
facilities. The Company expects these expenses to continue to grow as it
continues to invest in technology and infrastructure.

    Occupancy expense for the three months ended March 31, 2000 increased to
$792,000 from $90,000 for the three months ended March 31, 1999. As of
March 31, 1999, we leased one floor in our New York location. As a result of the
growth of our business and our merger with SoundView, we now lease several
floors in our New York location and we operate an office in Stamford,
Connecticut and an additional,

                                       12
<PAGE>
larger office in San Francisco. As we continue to grow and expand our business,
we expect occupancy expense to increase.

    Marketing and business development expense for the three months ended
March 31, 2000 increased to $3 million from $212,000 for the three months ended
March 31, 1999. Marketing and business development expense consists primarily of
travel, entertainment, advertising and costs associated with our conferences.
Marketing expense in 1999 primarily consists of travel, entertainment and other
costs associated with developing our investment banking business. We expect
these expenses to continue to increase as we continue to expand our investment
banking business and as we anticipate spending increased amounts on focused
marketing directed at issuers during the coming fiscal year.

    Other expenses for the three months ended March 31, 2000 increased to
$1.3 million from $145,000 for the three months ended March 31, 1999. Other
expenses include office supplies, registrations and other administrative
expenses which have all increased as we continue to expand our business and
operations.

    Equity in net loss of affiliates for the three months ended March 31, 2000
increased to $1.7 million from $0 for the three months ended March 31, 1999.
Equity in net loss of affiliates represents our proportional share of the losses
incurred by Wit Capital Japan and Wit Capital Europe based on our ownership
interest in each joint venture. We expect these losses to increase as Wit
Capital Japan and Wit Capital Europe prepare to commence operations in mid to
late 2000.

LIQUIDITY AND CAPITAL RESOURCES

    Historically, Wit Capital has satisfied its cash requirements primarily
through private placements of common stock and convertible preferred stock.
During June 1999, Wit Capital Group, Inc. completed an initial public offering
in which it issued 8,740,000 shares of its common stock at $9.00 per share. The
Company received approximately $72.8 million in cash proceeds, net of
underwriting discounts and offering costs. The Company believes that its
existing cash balances will be sufficient to meet anticipated cash requirements
for at least the next twelve months. We may, nonetheless, seek additional
financing to support our activities during the next twelve months or thereafter.
There can be no assurance, however, that additional capital will be available on
reasonable terms, if at all, when needed or desired.

    Net cash used in operating activities was $12.5 million for the three months
ended March 31, 2000, compared to $8.1 million during the same period in the
preceding year. Cash used in operating activities for the three months ended
March 31, 2000 was primarily from net income of $7.5 million, an increase in net
operating assets of $76.9 million offset by a net increase in operating
liabilities of $39.2 million. Cash used in operating activities for the three
months ended March 31, 1999 was primarily from a net loss of $4.9 million, a net
increase in operating assets of $4.5 million, and an increase in operating
liabilities of $1.1 million.

    Cash provided by investing activities was $54.1 million for the three months
ended March 31, 2000, compared to cash used of $543,000 for the three months
ended March 31, 1999. Cash provided by investing activities for the three months
ended March 31, 2000 was primarily for net purchases and sales of short-term
investments of $62.7 million, the acquisition of SoundView for $22.5 million
($6.8 million, net of cash received of $15.7 million), fixed asset purchases of
$1.1 million and purchases of computer software of $704,000. Cash used in
investing activities for the three months ended March 31, 1999 resulted from
purchases of fixed assets of $535,000 and from purchases of computer software of
$8,000.

    Cash provided by financing activities was $8.9 million for the three months
ended March 31, 2000, compared to $31.8 million for the three months ended
March 31, 1999. Cash provided by financing activities for the three months ended
March 31, 2000 resulted primarily from $8.9 million in proceeds received from
the issuance of common stock for exercise of options and warrants. Cash provided
by financing activities for the three months ending March 31, 1999 resulted
primarily from $31.6 million

                                       13
<PAGE>
received from issuances of the Company's Series D Preferred Stock, now common
stock, to accredited investors.

    The Company continues to use the net proceeds from its IPO for working
capital purposes. In January 2000, Wit Capital paid approximately $22.5 million
to shareholders of SoundView in connection with its merger with SoundView and in
March 2000, the Company invested $10 million in Internet HealthCare Group, a
business-to-business e-commerce company focused on e-healthcare and e-insurance.
The Company expects to continue to use the proceeds for working capital purposes
and for strategic acquisitions or investments.

ITEM 2--CHANGES IN SECURITIES AND USE OF PROCEEDS

    The Company continues to use the net proceeds from its IPO for working

    On January 31, 2000, the Company acquired by merger SoundView Technology
Group, Inc. for approximately 11.4 million shares and $22.5 million in cash.

    The Company has included in this Form 10-Q filing, and from time to time its
management may make, statements which may constitute forward-looking statements
within the meaning of the safe harbor provisions of the Private Securities

      profits;

    - increasing competitive pressures; and

    Additional information regarding these and other important factors that
