"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 the
date hereof (the "Initial Exercise Date") and on or prior to the close of

                                       1
<PAGE>

            1. 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.

            2. 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).

            3. 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.

                  (c) If no registration statement is effective permitting the
resale of the shares of Common Stock issued upon exercise of this Warrant at any
time commencing one year after the issuance date hereof, then this Warrant shall
also be exercisable by means of a "cashless exercise" in which the Holder shall
be entitled to receive a certificate for the number of shares equal to the
quotient obtained by dividing [(A-B) (X)] by (A), where:

                                       2
<PAGE>

(A) = the average of the high and low trading prices per share of Common Stock
on the Trading Day preceding the date of such election on the Nasdaq Stock
Market, or if the Common Stock is not traded on the Nasdaq Stock Market, then
the Principal Market in terms of volume, and converted into US Dollars;

(B) =  the Exercise Price of the Warrants; and

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

            4. 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.

            5. 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.

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

            7. 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

                                       3
<PAGE>

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.

            8. 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.

            9. 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.

            10. 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.

            11. 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

                                       4
<PAGE>

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
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.

            12. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant, reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

            13. 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

                                       5
<PAGE>

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.

            14. 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
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).

            15. 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

                                       6
<PAGE>

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.

            16. 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.

                  (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.

                                       7
<PAGE>

                  (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
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.

                            A.B. WATLEY GROUP INC.

            THIS CERTIFIES that, for value received, Ladenburg Thalmann & Co.
Inc. (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
the date hereof (the "Initial Exercise Date") and on or prior to the close of
business on August 9, 2003 (the "Termination Date") but not thereafter, to

incorporated in the State of Delaware (the "Company"), up to 70,893 shares (the
"Warrant Shares") of Common Stock, $0.001 par value, of the Company (the "Common

                                       1
<PAGE>

            1. 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.

            2. 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).

            3. 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.

                  (c) If no registration statement is effective permitting the
resale of the shares of Common Stock issued upon exercise of this Warrant at any
time commencing one year after the issuance date hereof, then this Warrant shall
also be exercisable by means of a "cashless exercise" in which the Holder shall
be entitled to receive a certificate for the number of shares equal to the
quotient obtained by dividing [(A-B) (X)] by (A), where:

                                       2
<PAGE>

(A) = the average of the high and low trading prices per share of Common Stock
on the Trading Day preceding the date of such election on the Nasdaq Stock
Market, or if the Common Stock is not traded on the Nasdaq Stock Market, then
the Principal Market in terms of volume, and converted into US Dollars;

(B) =  the Exercise Price of the Warrants; and

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

            4. 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.

            5. 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.

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

            7. 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

                                       3
<PAGE>

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.

            8. 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.

            9. 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.

            10. 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.

            11. 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

                                       4
<PAGE>

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
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.

            12. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant, reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

            13. 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

                                       5
<PAGE>

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.

            14. 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
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).

            15. 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

                                       6
<PAGE>

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.

            16. 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.

                  (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.

                                       7
<PAGE>

                  (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
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
