                             STOCK PURCHASE WARRANT

                 To Purchase 3,000,000 Shares of Common Stock of

                             A.B. WATLEY GROUP INC.

      THIS CERTIFIES that, for value received, Blue Marble Investments Ltd. (the
      "Holder"), is entitled, upon the terms and subject to the limitations on
      exercise and the conditions hereinafter set forth, at any time on or after
      March 8, 2006 (the "Initial Exercise Date") and on or prior to the close
      of business on March 8, 2016 (the "Termination Date") but not thereafter,
      to subscribe for and purchase from A.B. Watley Group Inc., a corporation
      incorporated in the State of Delaware (the "Company"), up to 3,000,000
      shares (the "Warrant Shares") of Common Stock, $0.001 par value, of the
      Company (the "Common Stock"). The purchase price of one share of Common
      Stock (the "Exercise Price") under this Warrant shall be $0.01. The
      Exercise Price and the number of shares for which the Warrant is
      exercisable shall be subject to adjustment as provided herein.

      Title to Warrant. Prior to the Termination Date and subject to compliance
      with applicable laws, this Warrant and all rights hereunder are
      transferable, in whole or in part, at the office or agency of the Company
      by the Holder hereof in person or by duly authorized attorney, upon
      surrender of this Warrant together with the Assignment Form annexed hereto
      properly endorsed.


                                       1
<PAGE>

      1. Authorization of Shares. The Company covenants that all shares of
Common Stock which may be issued upon the exercise of the purchase rights
represented by this Warrant will, upon exercise of the purchase rights
represented by this Warrant, be duly authorized, validly issued, fully paid and
nonassessable and free from all taxes, liens and charges in respect of the issue
thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue).

      2. Exercise of Warrant.

            (a) Exercise of the purchase rights represented by this Warrant may
be made at any time or times on or after the Initial Exercise Date, and before
the close of business on the Termination Date by the surrender of this Warrant
and the Notice of Exercise annexed hereto duly executed, at the office of the
Company (or such other office or agency of the Company as it may designate by
notice in writing to the registered Holder hereof at the address of such Holder
appearing on the books of the Company) and upon payment of the Exercise Price of
the shares thereby purchased by wire transfer or cashier's check drawn on a
United States bank, the Holder of this Warrant shall be entitled to receive a
certificate for the number of shares of Common Stock so purchased. Certificates
for shares purchased hereunder shall be delivered to the Holder hereof within
three (3) Trading Days after the date on which this Warrant shall have been
exercised as aforesaid. This Warrant shall be deemed to have been exercised and
such certificate or certificates shall be deemed to have been issued, and Holder
or any other person so designated to be named therein shall be deemed to have
become a Holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by Holder, if any, pursuant to Section 5 prior to
the issuance of such shares, have been paid.

            (b) If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the certificate or certificates representing
Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder
to purchase the unpurchased shares of Common Stock called for by this Warrant,
which new Warrant shall in all other respects be identical with this Warrant.

      3. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

      4. Charges, Taxes and Expenses. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the Holder hereof for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificates, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the Holder of this Warrant or in such name or names as may be directed by the
Holder of this Warrant; provided, however, that in the event certificates for
shares of Common Stock are to be issued in a name other than the name of the
Holder of this Warrant, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the Holder
hereof; and the Company may require, as a condition thereto, the payment of a
sum sufficient to reimburse it for any transfer tax incidental thereto.


                                       2
<PAGE>

      5. Closing of Books. The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant.

      6. Transfer, Division and Combination. (a) Subject to compliance with any
applicable securities laws, transfer of this Warrant and all rights hereunder,
in whole or in part, shall be registered on the books of the Company to be
maintained for such purpose, upon surrender of this Warrant at the principal
office of the Company, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the
making of such transfer. Upon such surrender and, if required, such payment, the
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination or denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

            (b) This Warrant may be divided or combined with other Warrants upon
presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by Holder or its agent or attorney. Subject to compliance
with Section 7(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

            (c) The Company shall prepare, issue and deliver at its own expense
(other than transfer taxes) the new Warrant or Warrants under this Section 7.

            (d) The Company agrees to maintain, at its aforesaid office, books
for the registration and the registration of transfer of the Warrants.

      7. No Rights as Stockholder until Exercise. This Warrant does not entitle
the Holder hereof to any voting rights or other rights as a stockholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price, the Warrant Shares so purchased shall
be and be deemed to be issued to such Holder as the record owner of such shares
as of the close of business on the later of the date of such surrender or
payment.

      8. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant certificate
or any stock certificate relating to the Warrant Shares, and in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to it
(which shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company
will make and deliver a new Warrant or stock certificate of like tenor and dated
as of such cancellation, in lieu of such Warrant or stock certificate.


                                       3
<PAGE>

      9. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

      10. Adjustments of Exercise Price and Number of Warrant Shares.

            (a) Stock Splits, etc. The number and kind of securities purchasable
upon the exercise of this Warrant and the Exercise Price shall be subject to
adjustment from time to time upon the happening of any of the following. In case
the Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the Holder of this Warrant shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which he would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the Holder of this Warrant shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

            (b) Reorganization, Merger, Consolidation or Disposition of Assets.
In case the Company shall reorganize its capital, consolidate or merge with or
into another corporation (where the Company is not the surviving corporation or
where there is a change in or distribution with respect to the Common Stock of
the Company), or sell, transfer or otherwise dispose of all or substantially all
its property, assets or business to another corporation and, pursuant to the
terms of such reorganization, merger, consolidation or sale, transfer or
disposition of assets, shares of common stock of the successor or acquiring
corporation, or any cash, shares of stock or other securities or property of any
nature whatsoever (including warrants or other subscription or purchase rights)
in addition to or in lieu of common stock of the successor or acquiring
corporation ("Other Property"), are to be received by or distributed to the
holders of Common Stock of the Company, then Holder shall have the right
thereafter to receive, upon exercise of this Warrant, the number of shares of
common stock of the successor or acquiring corporation or of the Company, if it
is the surviving corporation, and Other Property receivable upon or as a result
of such reorganization, merger, consolidation or disposition of assets by a
Holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event. In case of any such reorganization,
merger, consolidation or disposition of assets, the successor or acquiring
corporation (if other than the Company) shall expressly assume the due and
punctual observance and performance of each and every covenant and condition of
this Warrant to be performed and observed by the Company and all the obligations


                                       4
<PAGE>

and liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of shares of Common Stock
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 11. For purposes of
this Section 11, "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event, and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing provisions of
this Section 11 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

      11. Notice of Adjustment. Whenever the number of Warrant Shares or number
or kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
Holder of this Warrant notice of such adjustment or adjustments setting forth
the number of Warrant Shares (and other securities or property) purchasable upon
the exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

      12. Notice of Corporate Action. If at any time:

            (a) the Company shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

            (b) there shall be any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

            (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

      then, in any one or more of such cases, the Company shall give to Holder
(i) at least 30 days' prior written notice of the date on which a record date
shall be selected for such dividend, distribution, right to subscribe or right
or for determining rights to vote in respect of any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up, and (ii) in the case of any such
reorganization, reclassification, recapitalization, merger, consolidation, sale,
transfer, disposition, dissolution, liquidation or winding up, at least 30 days'
prior written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause also shall specify (i) the date on which


                                       5
<PAGE>

any such record is to be taken for the purpose of such dividend, distribution or
right, the date on which the holders of Common Stock shall be entitled to any
such dividend, distribution or right, and the amount and character thereof, and
(ii) the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Stock shall be entitled to exchange their shares of Common
Stock for securities or other property deliverable upon such disposition,
dissolution, liquidation or winding up. Each such written notice shall be
sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with Section
16(d).

      13. Authorized Shares. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                  The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

                  Before taking any action which would result in an adjustment
in the number of shares of Common Stock for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

      14. Miscellaneous.

            (a) Jurisdiction. This Warrant shall be binding upon any successors
or assigns of the Company. This Warrant shall constitute a contract under the
laws of New York, without regard to its conflict of law principles or rules, and
be subject to arbitration pursuant to the terms set forth in the Purchase
Agreement.


                                       6
<PAGE>

            (b) Restrictions. The Holder hereof acknowledges that the Warrant
Shares acquired upon the exercise of this Warrant, if not registered, will have
restrictions upon resale imposed by state and federal securities laws.

            (c) Nonwaiver and Expenses. No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully fails to comply with any provision of this Warrant, the
Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys' fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

            (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the Holder hereof by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.

            (e) Limitation of Liability. No provision hereof, in the absence of
affirmative action by Holder to purchase shares of Common Stock, and no
enumeration herein of the rights or privileges of Holder hereof, shall give rise
to any liability of Holder for the purchase price of any Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

            (f) Remedies. Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive the defense in any action for specific performance that a remedy at law
would be adequate.

            (g) Successors and Assigns. Subject to applicable securities laws,
this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to
be for the benefit of all Holders from time to time of this Warrant and shall be
enforceable by any such Holder or holder of Warrant Shares.

            (h) Indemnification. The Company agrees to indemnify and hold
harmless Holder from and against any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, reasonable attorneys' fees,
expenses and disbursements of any kind which may be imposed upon, incurred by or
asserted against Holder in any manner relating to or arising out of any failure
by the Company to perform or observe in any material respect any of its
covenants, agreements, undertakings or obligations set forth in this Warrant;
provided, however, that the Company will not be liable hereunder to the extent
that any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, attorneys' fees, expenses or disbursements are


                                       7
<PAGE>

found in a final non-appealable judgment by a court to have resulted from
Holder's negligence, bad faith or willful misconduct in its capacity as a
stockholder or warrantholder of the Company.

            (i) Amendment. This Warrant may be modified or amended or the
provisions hereof waived with the written consent of the Company and the Holder.

            (j) Severability. Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

            (k) Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

      IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
