                            FORM OF ESCROW AGREEMENT

         THIS ESCROW AGREEMENT, dated as of __________, [ ], 2000 (this "Escrow
Agreement"), is by and among Wit Capital Group, Inc., a corporation organized
under the laws of Delaware ("Parent "), E*TRADE Group, Inc. as the agent (the
"Shareholders' Agent") of the shareholders (the "Shareholders") of E*OFFERING
Corp., a California corporation (the "Company"), and [ ] as escrow agent (the
"Escrow Agent").

         Pursuant to the Agreement and Plan of Merger, dated as of May [ ], 2000
(the "Merger Agreement"), by and among Parent, Wit SoundView Corp., a
corporation organized under the laws of the State of Delaware ("Merger Sub"),
and the Company, the Company has been merged with and into Merger Sub (the
"Merger"). Capitalized terms not otherwise defined in this Escrow Agreement have
the meanings ascribed to them in the Merger Agreement.

         Pursuant to Section 10.1 of the Merger Agreement, [ ] shares of common
stock, $0.01 par value per share, of Parent (the "Escrow Shares") are being
deposited by Wit Capital Group, Inc. into the Escrow Fund established hereunder
on behalf of the Shareholders to provide for the indemnification of the
Indemnified Persons (as defined in the Merger Agreement) under Article X of the
Merger Agreement. The Final Allocation Schedule delivered by the Shareholders'
Agent pursuant to Section 4.1 of the Merger Agreement, a copy of which is
attached, sets forth the name of each Shareholder and the number of Escrow
Shares initially being deposited on each Shareholder's behalf.

         NOW THEREFORE, the parties hereto agree as follows:

         1. ESTABLISHMENT OF ESCROW. Parent has delivered to the Escrow Agent
and the Escrow Agent acknowledges receipt of the Escrow Shares in the form of a
single stock certificate registered in the name of the nominee of the Escrow
Agent [   ]. The Escrow Agent shall hold the Escrow Shares, and any dividends or
other distributions on the Escrow Shares and other securities or property into
which the Escrow Shares may be converted or reclassified into or exchanged for,
in escrow, in its name or the name of its nominee, in accordance with this
Escrow Agreement. The Escrow Shares shall not be subject to any lien,
attachment, trustee process or any other judicial process of any creditor of any
party hereto.
<PAGE>

         The Escrow Agent shall have no responsibility for the genuineness,
validity, market value, title or sufficiency for any intended purpose of the
Escrow Shares. The Escrow Agent shall be under no obligation to preserve,
protect or exercise rights in the Escrow Shares, and shall be responsible only
for reasonable measures to maintain the physical safekeeping thereof, and
otherwise to perform and observe such duties on its part as are expressly set
forth in this Agreement; except that the Escrow Agent shall, at the written
request of the Shareholders' Agent given to the Escrow Agent at least three (3)
business days prior to the date on which the Escrow Agent is requested therein
to take any action, deliver to the Shareholders' Agent a duly executed proxy or
other instrument in the form supplied to it by the Shareholders' Agent for
voting or otherwise exercising any right of consent with respect to any of the
Escrow Shares held by it hereunder, which proxy or other instrument shall
authorize the Shareholders' Agent to exercise such voting or consent authority
in respect of the Escrow Shares. The Escrow Agent shall not be responsible for
forwarding to any party, notifying any party with respect to, or taking any
action with respect to, any notice, solicitation or other document or
information, written or otherwise, received from Parent or other person with
respect to the Escrow Shares, including but not limited to, proxy material,
tenders, options, the pendency of calls and maturities and expiration of rights.

         2. DIVIDENDS AND DISTRIBUTIONS ON ESCROW SHARES. Until distributed
pursuant to the last paragraph of this Section 2, (a) the Escrow Agent shall
invest all cash dividends and other cash distributions, if any, on the Escrow
Shares (such cash dividends and other cash distributions are referred to herein
as the "Escrow Funds") at, and pursuant to, the written direction of the
Shareholders' Agent in Eligible Investments (as defined below) (including any
interest earned thereon) and shall not be responsible or liable for any loss
accruing from any investment made in accordance herewith and (b) the Escrow
Agent shall hold any noncash dividends and other noncash distributions on the
Escrow Shares.

         "Eligible Investments" means (a) obligations issued or guaranteed by
the United States of America or any agency or instrumentality thereof (provided
that the full faith and credit of the United States is pledged in support of
interest and principal thereto); (b) obligations (including certificates of
deposit and banker's acceptances) of any domestic commercial bank having capital
and surplus in excess of $500,000,000; (c) repurchase obligations for underlying
securities of the type described in clause (a); or (d) shares of any registered
money market fund at least 95% of the assets of which constitute obligations of
the type described in clause (a) above. No investment shall have a term of more
than 30 days. If otherwise qualified, obligations of the Escrow Agent shall
qualify as Eligible Investments.


                                       2
<PAGE>

         Absent its timely receipt of such specific written investment
instruction from the Shareholders' Agent, the Escrow Agent shall have no
obligation or duty to invest (or otherwise pay interest on) the Escrow Funds.
All earnings received from the investment of the Escrow Funds shall be credited
to, and shall become a part of, the Escrow Funds (and any losses on such
investments shall be debited to the Escrow Funds). The Escrow Agent shall have
no liability for any investment losses, including any losses on any investment
required to be liquidated prior to maturity in order to make a payment required
hereunder.

         3. TAX TREATMENT AND ALLOCATION. Dividends and other distributions on
the Escrow Shares, Escrow Funds and earnings thereon will be allocable for tax
purposes to the Shareholders in proportion to their respective Escrow Shares at
the time of such allocation and the Shareholders will include any such
allocations constituting income in their gross income for federal, state and
local income tax purposes and pay any tax resulting therefrom. The Shareholders'
Agent shall use his reasonable best efforts to provide the Escrow Agent with a
certified tax identification number for each Shareholder by arranging for
execution and return of a Form W-9 (or Form W-8, in the case of non-U.S.
persons) to the Escrow Agent prior to the date on which any such allocation is
made. The parties hereto acknowledge that in the event that the Shareholders'
tax identification numbers are not certified to the Escrow Agent, the Escrow
Agent may be required to withhold a portion of any interest or other income
earned on the Escrow Funds. The Escrow Agent will be permitted to withhold and
pay to the appropriate taxing authority any amount of the Escrow Shares, Escrow
Funds and earnings thereon that the Escrow Agent in its determination believes
is required to be withheld and paid to the applicable taxing authority.

         4. TAX INDEMNIFICATION. Each Shareholder: (i) assumes any and all
obligations imposed now or hereafter by any applicable tax law with respect to
any payment or distribution of the Escrow Funds, or performance of other
activities under this Escrow Agreement, with respect to the Shareholder's Escrow
Shares; (ii) shall instruct the Escrow Agent in writing with respect to the
Escrow Agent's responsibility for withholding and other taxes, assessments or
other governmental charges, and instruct the Escrow Agent with respect to any
certifications and governmental reporting that may be required under any laws or
regulations that may be applicable in connection with its acting as Escrow Agent
under this Escrow Agreement with respect to the Shareholder's Escrow Shares; and
(iii) shall indemnify and hold the Escrow Agent harmless from any liability or
obligation on account of taxes, assessments, additions for late payment,
interest, penalties, expenses and other governmental charges that may be
assessed or asserted against the Escrow Agent in connection with or relating to
any payment made or other activities performed under this Escrow Agreement with
respect to the Shareholder's Escrow Shares, including


                                       3
<PAGE>

without limitation any liability for the withholding or deduction of (or the
failure to withhold or deduct) the same, and any liability for failure to obtain
proper certifications or to report properly to governmental authorities in
connection with this Escrow Agreement, including costs and expenses (including
reasonable legal fees and expenses), interest and penalties.

         5. CLAIMS AGAINST ESCROW SHARES.

         At any time or times prior to the Expiration Date (as defined in
Section 7 of this Escrow Agreement), Parent may make claims against the Escrow
Shares for amounts potentially eligible for indemnification under Section 10.2
of the Merger Agreement by delivering to the Escrow Agent an Officer's
Certificate prepared in accordance with Section 10.4 of the Merger Agreement,
with a copy delivered at the same time to the Shareholders' Agent. Upon the
earliest of: (i) receipt of written authorization from the Shareholders' Agent
or from the Shareholders' Agent jointly with Parent to make such delivery, (ii)
receipt of written notice of a final decision in arbitration of the claim, (iii)
in the event the claim set forth in the Officer's Certificate is uncontested by
the Shareholders' Agent, in accordance with Section 10.5 of the Merger
Agreement, and if the aggregate amount of undisputed claims exceeds $3,000,000,
each such undisputed claim shall be deemed to have been acknowledged to be
payable from the Escrow Shares in the full amount of the Damages (as defined in
the Merger Agreement) set forth in the Officer's Certificate, and the Escrow
Agent shall pay such amount to Parent as soon as practicable after expiration of
the (twenty) 20 business day dispute period provided for in Section 10.5 of the
Merger Agreement. The Escrow Agent shall effect such payment of Escrow Shares to
Parent by surrendering the certificate representing the Escrow Shares to
Parent's transfer agent for cancellation with instructions to issue a new
certificate to the Escrow Agent for the number of Escrow Shares remaining after
giving effect to such payment and a certificate to Parent for the number of
Escrow Shares constituting such payment. If the amount of the claim exceeds the
aggregate value of the Escrow Shares, none of the Escrow Agent, the
Shareholders' Agent, the Shareholders or any Company Indemnified Person shall
have liability or responsibility for any deficiency. For purposes of determining
how many Escrow Shares shall be delivered in satisfaction of any claim, each
Escrow Share shall have a value equal to the average of the closing prices for
the common stock of Parent as reported for the primary trading session
(currently ending at 4:00 p.m. on the Nasdaq National Market) during the period
comprised of ten (10) consecutive trading days ending on the trading day two
business days preceding delivery of the Escrow Shares to Parent in satisfaction
of such claim (the "Escrow Share Value"). The number of Escrow Shares to be paid
to Parent by the Escrow Agent shall be calculated by dividing the amount of the
Damages to which such claim relates by the Escrow Share Value. Any payment to
Parent shall reduce the number of Escrow Shares in which


                                       4
<PAGE>

the Shareholder or Shareholders obligated to make such payment have an interest.
All claims paid out of the Escrow Shares shall be rounded to the nearest whole
share. If the shares of Parent common stock originally constituting the Escrow
Shares are converted or reclassified into or exchanged for any other securities
or property, the foregoing claim and payment provisions shall apply to such
other security or property. To the extent that the Escrow Agent is required to
deliver Escrow Shares to Parent under this Agreement, it shall deliver such
Escrow Shares based on the respective ownership of the Escrow Shares among the
shareholder parties.

         6. DISPUTED CLAIMS.

         The Shareholders' Agent may dispute any claim set forth on an Officer's
Certificate by giving written notice thereof to Parent and the Escrow Agent
within twenty (20) business days after the date Parent delivered the Officer's
Certificate to the Escrow Agent with a copy thereof to the Shareholder's Agent.
If the Shareholders' Agent disputes a claim, the Escrow Agent shall
provisionally allocate that portion of the Escrow Shares equal to 105% of the
amount of the Damages set forth in the copy of the Officer's Certificate (the
"Set Aside Amount") divided by the Escrow Share Value on the date such notice of
dispute is received and shall adjust the number of allocated Escrow Shares at
least once each quarter prior to resolution of such dispute. No distribution of
Escrow Shares allocated to a Set Aside Amount shall be made by the Escrow Agent
to Parent or to the Shareholders until such disputed claim has been resolved as
evidenced by a written notice executed by Parent and the Shareholders' Agent or
a court or arbitrator instructing the Escrow Agent as to the distribution of the
Escrow Shares allocated to such Set Aside Amount or portion thereof.

         7. TERMINATION

         On _______ [ ], 2001, (the "Expiration Date"), the Escrow Agent shall
deliver the remaining Escrow Shares to the Shareholders according to their
respective Escrow Shares then held in escrow, provided that the Escrow Agent
shall retain and continue to hold in escrow all Escrow Shares then allocated to
Set Aside Amounts until such time or time as such Escrow Shares may be
distributed pursuant to Section 6. This Escrow Agreement shall terminate upon
the later of the Expiration Date or the distribution of all the Escrow Shares in
accordance with this Escrow Agreement, provided that Section 4 shall survive
termination of this Escrow Agreement.


                                       5

         8. THE ESCROW AGENT.

                  (1) Notwithstanding anything herein to the contrary, the
Escrow Agent shall dispose of all or any part of the Escrow Shares as directed
by a writing jointly signed by the Shareholders' Agent and Parent within two (2)
business days of receipt of such notice. The reasonable fees and expenses of the
Escrow Agent in connection with the preparation of this Escrow Agreement and its
execution and performance of this Escrow Agreement as set forth on SCHEDULE II
hereto shall be borne out of the Escrow Shares. The Escrow Agent shall not be
liable for any act or failure to act under this Escrow Agreement, including any
and all claims made against the Escrow Agent as a result of its holding the
Escrow Shares or Escrow Funds in its own name, except for its own negligence,
bad faith or willful misconduct. Subject to the foregoing, the Escrow Agent
shall not be liable for, and Parent and the Shareholders shall, jointly and
severally, indemnify and hold harmless the Escrow Agent and its directors,
employees, officers, agents, successors and assigns against any losses or claims
(including reasonable out-of-pocket expenses and attorney fees) arising out of
any action taken or omitted hereunder and reasonable costs of investigation and
counsel fees and expenses which may be imposed on the Escrow Agent or reasonably
incurred by it in connection with its acceptance of this appointment or
performance of its duties hereunder. The Escrow Agent may decline to act and
shall not be liable for failure to act if in doubt as to its duties under this
Escrow Agreement. The Escrow Agent may act upon any instrument or signature
(including wire transfer instructions) believed by it to be genuine and may
assume that any person purporting to give any notice or instruction hereunder,
believed by it to be authorized, has been duly authorized to do so. The Escrow
Agent's duties shall be determined only with reference to the express duties set
forth in this Escrow Agreement, each of which duties are ministerial in nature,
and applicable law and the Escrow Agent shall not be deemed to be a fiduciary
and is not charged with knowledge of or any duties or responsibilities in
connection with any other document or agreement, including without limitation,
the Merger Agreement; and the parties hereto agree that the use of defined terms
incorporated by reference to the Merger Agreement is solely for the convenience
of the other parties and the Escrow Agent may rely on the use of defined terms
in any communication received by it. In no event will the Escrow Agent be liable
for punitive, special or consequential damages or losses (including lost
profits) whatsoever, even if the Escrow Agent has been informed of the
likelihood of such damages or losses.


                                       6
<PAGE>

                  (2) The Escrow Agent shall have the right at any time to
resign hereunder by giving written notice of its resignation to the parties
hereto, at the addresses set forth herein or at such other address as the
parties shall provide, at least thirty days prior to the date specified for such
resignation to take effect. In such event Parent shall with the approval of the
Shareholders' Agent, which approval shall not be unreasonably withheld, appoint
a successor escrow agent within that thirty-day period; if Parent does not
designate a successor escrow agent within such period, the Escrow Agent may
appoint a successor escrow agent. Upon the effective date of such resignation,
the Escrow Shares and Escrow Fund then held by the Escrow Agent hereunder shall
be delivered by it to such successor escrow agent or as otherwise shall be
designated in writing by Parent and the Shareholders' Agent. If no successor
escrow agent is appointed as provided herein, the Escrow Agent may apply to a
court of competent jurisdiction for appointment of a successor escrow agent.

                  (3) In the event that the Escrow Agent should at any time be
(i) confronted with inconsistent or conflicting claims or demands by the other
parties hereto or (ii) unsure of its duties hereunder, the Escrow Agent shall
have the right to inter plead the parties in any Delaware court or any court of
competent jurisdiction and request that such court determine the respective
rights of the parties with respect to this Escrow Agreement and, upon doing so,
the Escrow Agent shall be released from any obligations or liability to the
other parties as a consequence of any such claims or demands. The Escrow Agent
may consult counsel satisfactory to it, including in-house counsel, and will be
protected in respect of any action taken or omitted in reliance thereon.

                  (4) The Escrow Agent may execute any of its powers or
responsibilities hereunder and exercise any rights hereunder, either directly or
by or through its agents or attorneys. Nothing in this Escrow Agreement shall be
deemed to impose upon the Escrow Agent any duty to qualify to do business in any
jurisdiction other than Delaware or to act as fiduciary. The Escrow Agent shall
not be responsible for and shall not be under a duty to examine, inquire into or
pass upon the validity, binding effect, execution or sufficiency of this Escrow
Agreement or of any amendment or supplement hereto.

         9. SHAREHOLDERS' AGENT.

than any such book-entry depository, securities intermediary or other subescrow
