                  5.9 No General Solicitation. The Investor did not learn of the
investment in the Securities as a result of any public advertising or general
solicitation.

         6. Registration Rights Agreement. The parties acknowledge and agree
that part of the inducement for the Investor to enter into this Agreement is the
Company's execution and delivery of the Registration Rights Agreement. The
parties acknowledge and agree that simultaneously with the execution hereof, the
Registration Rights Agreement is being duly executed and delivered by the
parties thereto.

         7. Covenants and Agreements of the Company.

                  7.1 Opinion of Counsel. On or prior to the Closing Date, the
Company will deliver to the Investors the opinion of legal counsel to the
Company, in form and substance reasonably acceptable to the Investors,
addressing those legal matters set forth in Schedule 7.2 hereto.

                  7.2 Reservation of Common Stock Pursuant to Exercise of
Penalty Warrants. The Company hereby agrees that if any Penalty Warrants are
issued, it shall at all times prior to exercise or expiration thereof reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the purpose of providing for the exercise of the Penalty Warrants,
such number of shares of Common Stock as shall from time to time equal the
number of shares sufficient to permit the exercise of the Penalty Warrants in
accordance with the terms of the Penalty Warrants.

                  7.3 No Conflicting Agreements. The Company will not take any
action, enter into any agreement or make any commitment that would conflict or
interfere in any material respect with the obligations to the Investors under
the Agreements.

                  7.4 Listing of Underlying Shares and Related Matters. The
Company hereby agrees, following the Closing of the transactions contemplated by
this Agreement, to take such


                                       10
<PAGE>


action to cause the Shares and (if applicable) the Penalty Warrant Shares to be
listed on the Nasdaq National Market as promptly as possible but no later than
the effective date of the registration contemplated by the Registration Rights
Agreement. The Company further agrees that if the Company applies to have its
Common Stock or other securities traded on any other principal stock exchange or
market, it will include in such application the Penalty Warrant Shares and will
take such other action as is necessary to cause such Common Stock to be so
listed. For so long as the Investors beneficially own any of the Securities, the
Company will take all action necessary to continue the listing and trading of
its Common Stock on the Nasdaq National Market and will comply in all respects
with the Company's reporting, filing and other obligations under the bylaws or
rules of such exchange, as applicable, to ensure the continued eligibility for
trading of the Shares and the Penalty Warrant Shares thereon. Notwithstanding
anything to the contrary in this section, the Company shall be under no
obligation to list any Penalty Warrant Shares until such time as Penalty
Warrants shall have been issued.

         8. Survival and Indemnification.

                  8.1 Survival. All representations, warranties, covenants and
agreements contained in this Agreement shall be deemed to be representations,
warranties, covenants and agreements as of the date hereof and shall survive the
execution and delivery of this Agreement for a period of twelve months from the
date of this Agreement; provided, however, that the provisions contained in
Section 7 hereof shall survive in accordance therewith.

                  8.2 Indemnification.

                           (a) The Company agrees to indemnify and hold
harmless, on an after-tax and after insurance recovery basis, each holder of
Securities and its Affiliates and their respective directors, officers,
employees and agents (each, an "Investor Indemnified Person") from and against
any and all losses, claims, damages, liabilities and expenses (including without
limitation reasonable attorney fees and disbursements and other expenses
incurred in connection with investigating, preparing or defending any action,
claim or proceeding, pending or threatened and the costs of enforcement hereof)
(collectively, "Losses") to which such Person may become subject as a result of
any breach of representation, warranty, covenant or agreement made by or to be
performed on the part of the Company under the Agreements and will reimburse any
such Person for all such amounts as they are incurred by such Person; provided,
however, that if an Investor Indemnified Person is reimbursed under this Section
8.2 for any expenses, such reimbursement of expenses shall be refunded to the
extent it is finally judicially determined that the Losses in question resulted
primarily from the wilful misconduct or gross negligence of such Investor
Indemnified Person.

                           (b) Each Investor, severally and not jointly, agrees
to indemnify and hold harmless, on an after-tax and after insurance recovery
basis, the Company and its Affiliates and their respective directors, officers,
employees and agents (each, a "Company Indemnified Person") from and against any
and all Losses to which such Person may become subject as a result of any breach
of representation, warranty, covenant or agreement made by or to be performed on
the part of such Investor under the Agreements and will reimburse any such
Person for all such amounts as they are incurred by such Person; provided,
however, that if a Company


                                       11
<PAGE>


Indemnified Person is reimbursed under this Section 8.2 for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally
judicially determined that the Losses in question resulted primarily from the
wilful misconduct or gross negligence of such Company Indemnified Person.

                  8.3 Conduct of Indemnification Proceedings. Promptly after
receipt by any Investor Indemnified Person or Company Indemnified Person (an
"Indemnified Person") of notice of any demand, claim or circumstances which
would or might give rise to a claim or the commencement of any action,
proceeding or investigation in respect of which indemnity may be sought pursuant
to Section 8.2, such Indemnified Person shall promptly notify the party
responsible for providing such indemnification (the "Indemnifying Person") in
writing and the Indemnifying Person shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Person,
and shall assume the payment of all fees and expenses; provided, however, that
the failure of any Indemnified Person so to notify the Indemnifying Person shall
not relieve the Indemnifying Person of its obligations hereunder except to the
extent that the Indemnifying Person is materially prejudiced by such failure to
notify. In any such proceeding, any Indemnified Person shall have the right to
retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Person unless: (i) the Indemnifying Person and
the Indemnified Person shall have mutually agreed to the retention of such
counsel; or (ii) in the reasonable judgment of such Indemnified Person, based
upon written advice of its counsel, representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. The Indemnifying Person shall not be liable for any settlement of
any proceeding effected without its written consent, which consent shall not be
unreasonably withheld, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Indemnifying Person shall indemnify and hold
harmless such Indemnified Person from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment. Without the prior
written consent of the Indemnified Person, the Indemnifying Person shall not
effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Party, unless such settlement
includes an unconditional release of such Indemnified Person from all liability
arising out of such proceeding.

         9. Miscellaneous.

                  9.1 Successors and Assigns. This Agreement may not be assigned
by a party hereto without the prior written consent of the other party hereto,
except that without the prior written consent of the Company, but after notice
duly given, an Investor may assign its rights and delegate its duties hereunder
in whole or in part to an Affiliate, and without the prior written consent of
the Investors, but after notice duly given and in compliance with this
Agreement, the Company may assign its rights and delegate its duties hereunder
to any successor-in-interest corporation in the event of a merger or
consolidation of the Company with or into another corporation, or any merger or
consolidation of another corporation with or into the Company that results
directly or indirectly in an aggregate change in the ownership or control of
more than 50% of the voting rights of the equity securities of the Company, or
the sale of all or substantially all of the Company's assets. The terms and
conditions of this Agreement shall inure to the benefit

Investor of any Securities in compliance with all applicable securities laws.

                                    EXHIBIT A



THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED,
ASSIGNED, PLEDGED, OFFERED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE APPLICABLE SECURITIES LAWS OR AN
OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY STATING THAT SUCH REGISTRATION IS
NOT REQUIRED.

         SUBJECT TO THE PROVISIONS OF SECTION 10 HEREOF, THIS WARRANT SHALL
BECOME VOID AFTER 5:00 P.M. EASTERN TIME ON OCTOBER 11, 2006 ("EXPIRATION
DATE").

                              VISIONICS CORPORATION

                      WARRANT TO PURCHASE 36,036 SHARES OF
             COMMON STOCK, $.01 PAR VALUE PER SHARE ("COMMON STOCK")

         For VALUE RECEIVED, Morgan Keegan & Company, Inc. ("Warrantholder"), is
entitled to purchase, subject to the provisions of this Warrant, from Visionics
Corporation, a Delaware corporation ("Company"), at any time not later than 5:00
P.M., Eastern time, on the Expiration Date, at an exercise price per share equal
to $16.86 (the exercise price in effect being herein called the "Warrant
Price"), 36,036 shares ("Warrant Shares") of Common Stock. The number of Warrant
Shares purchasable upon exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time as described herein.

         Section 1. Registration. The Company shall maintain books for the
transfer and registration of the Warrant. Upon the initial issuance of the
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

         Section 2. Transfers. As provided herein, this Warrant may be
transferred only pursuant to a registration statement filed under the Securities
Act of 1933, as amended ("Securities Act") or an exemption from such
registration. Subject to such restrictions, the Company shall transfer this
Warrant from time to time upon the books to be maintained by the Company for
that purpose, upon surrender thereof for transfer properly endorsed or
accompanied by appropriate instructions for transfer and such other documents as
may be reasonably required by the Company to establish that such transfer is
being made in accordance with the terms hereof, and a new Warrant shall be
issued to the transferee and the surrendered Warrant shall be canceled by the
Company.

         Section 3. Exercise of Warrant. Subject to the provisions hereof, the
Warrantholder may exercise this Warrant in whole or in part at any time upon
surrender of the Warrant, together with delivery of the duly executed Warrant
exercise form attached hereto as Appendix A (the "Exercise Agreement") and
payment by cash, certified check or wire transfer of funds (or by cashless
exercise as provided below) for the Warrant Price for that number of Warrant
Shares then being purchased, to the Company during normal business hours on any
business day at the Company's principal executive offices (or such other office
or agency of the Company as it may

<PAGE>


designate by notice to the holder hereof). The Warrant Shares so purchased shall
be deemed to be issued to the holder hereof or such holder's designee, as the
record owner of such shares, as of the close of business on the date on which
this Warrant shall have been surrendered (or evidence of loss, theft or
destruction thereof and security or indemnity satisfactory to the Company shall
have been provided to the Company), the Warrant Price shall have been paid and
the completed Exercise Agreement shall have been delivered. Certificates for the
Warrant Shares so purchased, representing the aggregate number of shares
specified in the Exercise Agreement, shall be delivered to the holder hereof
within a reasonable time, not exceeding seven (7) business days, after this
Warrant shall have been so exercised. The certificates so delivered shall be in
such denominations as may be requested by the holder hereof and shall be
registered in the name of such holder or such other name as shall be designated
by such holder. If this Warrant shall have been exercised only in part, then,
unless this Warrant has expired, the Company shall, at its expense, at the time
of delivery of such certificates, deliver to the holder a new Warrant
representing the number of shares with respect to which this Warrant shall not
then have been exercised.

                  Each exercise hereof shall constitute the representation and
warranty of the Warrantholder to the Company that the representations and
warranties contained in Article 5 of the Purchase Agreement (as defined below)
are true and correct in all material respects with respect to the Warrantholder
as of the time of such exercise.

         Section 4. Compliance with the Securities Act of 1933. The Company may
cause the legend set forth on the first page of this Warrant to be set forth on
each Warrant or similar legend on any security issued or issuable upon exercise
of this Warrant, unless counsel for the Company is of the opinion as to any such
security that such legend is unnecessary.

         Section 5. Payment of Taxes. The Company will pay any documentary stamp
taxes attributable to the initial issuance of Warrant Shares issuable upon the
exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates for Warrant Shares in a
name other than that of the registered holder of this Warrant, and in such case,
the Company shall not be required to issue or deliver any certificate for
Warrant Shares or any Warrant until the person requesting the same has paid to
the Company the amount of such tax or has established to the Company's
reasonable satisfaction that such tax has been paid. The holder shall be
responsible for income taxes due under federal, state or other law, if any such
tax is due.

         Section 6. Mutilated or Missing Warrants. In case this Warrant shall be
mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and
substitution of and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the Warrant lost, stolen or destroyed, a new Warrant of
like tenor and for the purchase of a like number of Warrant Shares, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond with respect thereto, if
requested by the Company.

         Section 7. Reservation of Common Stock. The Company hereby represents
and warrants that there have been reserved, and the Company shall at all
applicable times keep reserved until


                                       2
<PAGE>


issued (if necessary) as contemplated by this Section 7, out of the authorized
and unissued Common Stock, sufficient shares to provide for the exercise of the
rights of purchase represented by the Warrant. The Company agrees that all
Warrant Shares issued upon exercise of the Warrant shall be, at the time of
delivery of the certificates for such Warrant Shares, duly authorized, validly
issued, fully paid and non-assessable shares of Common Stock of the Company.

         Section 8. Adjustments. Subject and pursuant to the provisions of this
Section 8, the Warrant Price and number of Warrant Shares subject to this
Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

                  (a) If the Company shall at any time or from time to time
while the Warrant is outstanding, pay a dividend or make a distribution on its
Common Stock in shares of Common Stock, subdivide its outstanding shares of
Common Stock into a greater number of shares or combine its outstanding shares
of Common Stock into a smaller number of shares or issue by reclassification of
its outstanding shares of Common Stock any shares of its capital stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then the number of
Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in
effect immediately prior to the date upon which such change shall become
effective, shall be adjusted by the Company so that the Warrantholder thereafter
exercising the Warrant shall be entitled to receive the number of shares of
Common Stock or other capital stock which the Warrantholder would have received
if the Warrant had been exercised immediately prior to such event upon payment
of a Warrant Price that has been adjusted to reflect a fair allocation of the
economics of such event to the Warrantholder. Such adjustments shall be made
successively whenever any event listed above shall occur.

                  (b) If any capital reorganization, reclassification of the
capital stock of the Company, consolidation or merger of the Company with
another corporation in which the Company is not the survivor, or sale, transfer
or other disposition of all or substantially all of the Company's assets to
another corporation shall be effected, then, as a condition of such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition, lawful and adequate provision shall be made whereby each
Warrantholder shall thereafter have the right to purchase and receive upon the
basis and upon the terms and conditions herein specified and in lieu of the
Warrant Shares immediately theretofore issuable upon exercise of the Warrant,
such shares of stock, securities or assets as would have been issuable or
payable with respect to or in exchange for a number of Warrant Shares equal to
the number of Warrant Shares immediately theretofore issuable upon exercise of
the Warrant, had such reorganization, reclassification, consolidation, merger,
sale, transfer or other disposition not taken place, and in any such case
appropriate provision shall be made with respect to the rights and interests of
each Warrantholder to the end that the provisions hereof (including, without
limitation, provision for adjustment of the Warrant Price) shall thereafter be
applicable, as nearly equivalent as may be practicable in relation to any shares
of stock, securities or properties thereafter deliverable upon the exercise
thereof. The Company shall not effect any such consolidation, merger, sale,
transfer or other disposition unless prior to or simultaneously with the
consummation thereof the successor corporation (if other than the Company)
resulting from such consolidation or merger, or the corporation purchasing or
otherwise acquiring such assets or other appropriate corporation or entity shall
assume the obligation to deliver to the holder of the Warrant such shares of
stock,


                                       3
<PAGE>


securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase, and the other obligations under this
Warrant. The provisions of this paragraph (b) shall similarly apply to
successive reorganizations, reclassifications, consolidations, mergers, sales,
transfers or other dispositions.

                  (c) In case the Company shall fix a payment date for the
making of a distribution to all holders of Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness or assets
(other than cash dividends or cash distributions payable out of consolidated
earnings or earned surplus or dividends or distributions referred to in Section
8(a)), or subscription rights or warrants, the Warrant Price to be in effect
after such payment date shall be determined by multiplying the Warrant Price in
effect immediately prior to such payment date by a fraction, the numerator of
which shall be the total number of shares of Common Stock outstanding multiplied
by the Market Price per share of Common Stock (as defined below), less the fair
market value (as determined by the Company's Board of Directors in good faith)
of said assets or evidences of indebtedness so distributed, or of such
subscription rights or warrants, and the denominator of which shall be the total
number of shares of Common Stock outstanding multiplied by such Market Price per
share of Common Stock. "Market Price" as of a particular date (the "Valuation
Date") shall mean the following: (a) if the Common Stock is then listed on a
national stock exchange, the closing sale price of one share of Common Stock on
such exchange on the last trading day prior to the Valuation Date; (b) if the
Common Stock is then quoted on the Nasdaq National Market ("Nasdaq"), the
closing sale price of one share of Common Stock on Nasdaq on the last trading
day prior to the Valuation Date or, if no such closing sale price is available,
the average of the high bid and the low sales price quoted on Nasdaq on the last
trading day prior to the Valuation Date; or (c) if the Common Stock is not then
listed on a national stock exchange or quoted on Nasdaq, the fair market value
of one share of Common Stock as of the Valuation Date, which shall be determined
in good faith by the Board of Directors of the Company and the Warrantholder.
The Board of Directors of the Company shall respond promptly, in writing, to an
inquiry by the Warrantholder prior to the exercise hereunder as to the Market
Value of a share of Common Stock as determined by the Board of Directors of the
Company. In the event that the Board of Directors of the Company and the
Warrantholder are unable to agree upon the fair market value in respect of
subpart (c) hereof, the Company and the Warrantholder shall jointly select an
appraisor, who is experienced in such matters. The decision of such appraiser
shall be final and conclusive, and the cost of such appraiser shall be borne
evenly by the Company and the Warrantholder. Such adjustment shall be made
successively whenever such a payment date is fixed.

                  (d) For the term of this Warrant, in addition to the
provisions contained above, the Warrant Price shall be subject to adjustment as
provided below. An adjustment to the Warrant Price shall become effective
immediately after the payment date in the case of each dividend or distribution
and immediately after the effective date of each other event which requires an
adjustment.

                  (e) In the event that, as a result of an adjustment made
pursuant to Section 8(a), the holder of this Warrant shall become entitled to
receive any shares of capital stock of the Company other than shares of Common
Stock, the number of such other shares so receivable upon exercise of this
Warrant shall be subject thereafter to adjustment from time to time in a manner
and on terms as nearly equivalent as practicable to the provisions with respect
to the Warrant Shares contained in this Warrant.

                  (f) Except as provided in subsection (g) hereof, if and
whenever the Company shall issue or sell, or is, in accordance with any of
subsections (f)(l) through (f)(7) hereof, deemed to have issued or sold, any
shares of Common Stock for a consideration per share less than the Warrant Price
in effect immediately prior to the time of such issue or sale, then and in each
such case (a "Trigger Issuance") the then-existing Warrant Price, shall be
reduced, as of the close of business on the effective date of the Trigger
Issuance, to a price determined as follows:


                           Adjusted Warrant Price  =  (A x B) + D
                                                      -----------
                                                          A+C
                                          where

                           "A" equals the number of shares of Common Stock
         outstanding (including any Additional Shares of Common Stock (as
         defined below) immediately preceding such Trigger Issuance);

                           "B" equals the Warrant Price in effect immediately
         preceding such Trigger Issuance;

                           "C" equals the number of Additional Shares of Common
         Stock (as adjusted for stock splits, stock combinations,
         recapitalizations, and dividends and the like) issued or deemed issued
         hereunder as a result of all Trigger Issuances; and

                           "D" equals the aggregate consideration, if any,
         received or deemed to be received by the Company upon such Trigger
         Issuance.

                  For purposes of this subsection (f), "Additional Shares of
Common Stock" shall mean all shares of Common Stock issued by the Company or
deemed to be issued pursuant to this subsection (f), other than Excluded
Issuances (as defined in subsection (g) hereof).

                  For purposes of this subsection (f), the following subsections
(f)(l) to (f)(7) shall also be applicable (subject, in each such case, to the
provisions of subsection (g) hereof) and to each other subsection contained in
this subsection (f):

         (f)(1) Issuance of Rights or Options. In case at any time the Company
         shall in any manner grant (directly and not by assumption in a merger
         or otherwise) any warrants or other rights to subscribe for or to
         purchase, or any options for the purchase of, Common Stock or any stock
         or security convertible into or exchangeable for Common Stock (such
         warrants, rights or options being called "Options" and such convertible
         or exchangeable stock or securities being called "Convertible
         Securities") whether or not such Options or the right to convert or
         exchange any such Convertible Securities are immediately exercisable,
         and the price per share for which Common Stock is issuable upon the
         exercise of such Options or upon the conversion or exchange of such
         Convertible Securities (determined by dividing (i) the sum (which sum
         shall constitute the applicable consideration (the "Consideration")) of
         (x) the total amount, if any, received or receivable


                                       5

         by the Company as consideration for the granting of such Options, plus
         (y) the aggregate amount of additional consideration payable to the
         Company upon the exercise of all such Options, plus (z), in the case of
         such Options which relate to Convertible Securities, the aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (ii) the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such Options) shall be less than the Warrant Price in effect
         immediately prior to the time of the granting of such Options, then the
         total number of shares of Common Stock issuable upon the exercise of
         such Options or upon conversion or exchange of the total amount of such
         Convertible Securities issuable upon the exercise of such Options shall
         be deemed to have been issued for such price per share as of the date
         of granting of such Options or the issuance of such Convertible
         Securities and thereafter shall be deemed to be outstanding for
         purposes of adjusting the Warrant Price. Except as otherwise provided
         in subsection 8(f)(3), no adjustment of the Warrant Price shall be made
         upon the actual issue of such Common Stock or of such Convertible
         Securities upon exercise of such Options or upon the actual issue of
         such Common Stock upon conversion or exchange of such Convertible
         Securities.

         (f)(2) Issuance of Convertible Securities. In case the Company shall in
         any manner issue (directly and not by assumption in a merger or
         otherwise) or sell any Convertible Securities, whether or not the
         rights to exchange or convert any such Convertible Securities are
         immediately exercisable, and the price per share for which Common Stock
         is issuable upon such conversion or exchange (determined by dividing
         (i) the sum (which sum shall constitute the applicable Consideration)
         of (x) the total amount received or receivable by the Company as
         consideration for the issue or sale of such Convertible Securities,
         plus (y) the aggregate amount of additional consideration, if any,
         payable to the Company upon the conversion or exchange thereof, by (ii)
         the total number of shares of Common Stock issuable upon the conversion
         or exchange of all such Convertible Securities) shall be less than the
         Warrant Price in effect immediately prior to the time of such issue or
         sale, then the total maximum number of shares of Common Stock issuable
         upon conversion or exchange of all such Convertible Securities shall be
         deemed to have been issued for such price per share as of the date of
         the issue or sale of such Convertible Securities and thereafter shall
         be deemed to be outstanding for purposes of adjusting the Warrant
         Price, provided that (a) except as otherwise provided in subsection
         8(f)(3), no adjustment of the Warrant Price shall be made upon the
         actual issuance of such Common Stock upon conversion or exchange of
         such Convertible Securities and (b) no further adjustment of the
         Warrant Price shall be made by reason of the issue or sale of
         Convertible Securities upon exercise of any Options to purchase any
         such Convertible Securities for which adjustments of the Warrant Price
         have been made pursuant to other provisions of this subsection 8(f)(2).

         (f)(3) Change in Option Price or Conversion Rate. Upon the happening of
         any of the following events, namely, if the purchase price provided for
         in any Option referred to in subsection 8(f)(l) hereof, the additional
         consideration, if any, payable upon the conversion or exchange of any
         Convertible Securities referred to in subsections 8(f)(l) or 8(f)(2),
         or the rate at which Convertible Securities referred to in subsections
         8(f)(l) or 8(f)(2) are convertible into or exchangeable for Common
         Stock shall change at any time (including,


                                       6
<PAGE>


         but not limited to, changes under or by reason of provisions designed
         to protect against dilution), the Warrant Price in effect at the time
         of such event shall forthwith be readjusted to the Warrant Price which
         would have been in effect at such time had such Options or Convertible
         Securities still outstanding provided for such changed purchase price,
         additional consideration or conversion rate, as the case may be, at the
         time initially granted, issued or sold; and on the termination of any
         such Option or any such right to convert or exchange such Convertible
         Securities (including without limitation upon the redemption or
         purchase for Consideration of all such Convertible Securities by the
         Company), the Warrant Price then in effect hereunder shall forthwith be
         changed to the Warrant Price which would have been in effect at the
         time of such termination had such Option or Convertible Securities, to
         the extent outstanding immediately prior to such termination, never
         been issued.

         (f)(4) Stock Dividends. Subject to the provisions hereof, in case the
         Company shall declare a dividend or make any other distribution upon
         any stock of the Company (other than the Common Stock) payable in
         Common Stock, Options or Convertible Securities, then any Common Stock,
         Options or Convertible Securities, as the case may be, issuable in
         payment of such dividend or distribution shall be deemed to have been
         issued or sold without consideration.

         (f)(5) Consideration for Stock. In case any shares of Common Stock,
         Options or Convertible Securities shall be issued or sold for cash, the
         Consideration received therefor shall be deemed to be the net amount
         received by the Company therefor, after deduction therefrom of any
         expenses incurred or any underwriting commissions or concessions paid
         or allowed by the Company in connection therewith. In case any shares
         of Common Stock, Options or Convertible Securities shall be issued or
         sold for a Consideration other than cash, the amount of the
         Consideration other than cash received by the Company shall be deemed
         to be the fair value of such Consideration as determined in good faith
         by the Board of Directors of the Company, after deduction of any
         expenses incurred or any underwriting commissions or concessions paid
         or allowed by the Company in connection therewith. In case any Options
         shall be issued in connection with the issue and sale of other
         securities of the Company, together comprising one integral transaction
         in which no specific consideration is allocated to such Options by the
         parties thereto, such Options shall be deemed to have been issued for
         such consideration as determined in good faith by the Board of
         Directors of the Company.

         (f)(6) Record Date. In case the Company shall take a record of the
         holders of its Common Stock for the purpose of entitling them (i) to
         receive a dividend or other distribution payable in Common Stock,
         Options or Convertible Securities or (ii) to subscribe for or purchase
         Common Stock, Options or Convertible Securities, then such record date
         shall be deemed to be the date of the issue or sale of the shares of
         Common Stock deemed to have been issued or sold upon the declaration of
         such dividend or the making of such other distribution or the date of
         the granting of such right of subscription or purchase, as the case may
         be.

         (f)(7) Treasury Shares. The number of shares of Common Stock
         outstanding at any given time shall not include shares owned or held by
         or for the account of the Company


                                       7
<PAGE>


         or any of its wholly-owned subsidiaries, and the disposition of any
         such shares shall be considered an issue or sale of Common Stock for
         the purpose of this subsection (f).

                  (g) Anything herein to the contrary notwithstanding, the
Company shall not be required to make any adjustment of the Warrant Price in the
case of the issuance of any of (A) capital stock, Options or Convertible
Securities issued to directors, officers, employees or consultants of the
Company in connection with their service as directors of the Company, their
employment by the Company or their retention as consultants by the Company
pursuant to an equity compensation program approved by the Board of Directors of
the Company or the compensation committee of the Board of Directors of the
Company, (B) sales of shares of Common Stock upon the conversion or exercise of
Options or Convertible Securities issued prior to the date hereof or (C) capital
stock issued as full or partial consideration for a merger or acquisition, or a
strategic allegiance or alliance in which the Company with respect to such
strategic allegiance or alliance issues shares of its equity securities having
an aggregate Fair Market Value (as defined below) of less than $10 million,
approved by the Board of Directors of the Company. The "Fair Market Value" of a
security as of a particular date (the "Valuation Date") shall mean the
following: (a) if the security is then listed on a national stock exchange, the
closing sale price of one security on such exchange on the last trading day
prior to the Valuation Date; (b) if the security is then quoted on Nasdaq, the
closing sale price of one security on Nasdaq on the last trading day prior to
the Valuation Date or, if no such closing sale price is available, the average
of the high bid and the low sales price quoted on Nasdaq on the last trading day
prior to the Valuation Date; or (c) if the security is not then listed on a
national stock exchange or quoted on Nasdaq, the fair market value of one
security as of the Valuation Date, shall be determined in good faith by a
nationally selected investment banking firm or other nationally recognized
business appraiser selected by the Board of Directors of the Company. The
decision of such appraiser shall be final and conclusive, and the cost of such
appraiser shall be borne evenly by the Company and the Investors (pro rata in
respect of their ownership of Securities at such time) as such terms are defined
in that certain Purchase Agreement among the Company and the Investors dated
October 5, 2001. An "Excluded Issuance" shall mean each of items (A), (B) and
(C) above.

         Section 9. Fractional Interest. The Company shall not be required to
issue fractions of Warrant Shares upon the exercise of the Warrant. If any
fractional share of Common Stock would, except for the provisions of the first
sentence of this Section 9, be delivered upon such exercise, the Company, in
lieu of delivering such fractional share, shall pay to the exercising holder of
this Warrant an amount in cash equal to the current Fair Market Value of such
fractional share of Common Stock.

         Section 10. Extension of Expiration Date. If the Company fails to cause
any Registration Statement covering Registrable Securities (capitalized terms
used in this section are as defined in the Registration Rights Agreement dated
October 5, 2001) (the "Registration Rights Agreement") to be declared effective
prior to the applicable dates set forth therein, or if any of the events
specified in clause (B) or (C) of Section 2(c) of the Registration Rights
Agreement occurs and the Blackout Period (whether alone, or in combination with
any other Blackout Period) continues for more than 60 days in any 12 month
period, or for more than a total of 90 days, then the Expiration Date of this
Warrant shall be extended one day for each day beyond the 60-day or 90-day
limits, as the case may be, that the Blackout Period continues.

contract made under the laws of the State of New York, without giving effect to
its conflict of law principles, and for all purposes shall be construed in
accordance with the laws of said State; provided, however, that, insofar as the

such number of fully paid, validly issued and nonassessable shares of Common
Stock as is computed using the following formula:

                                  X = Y (A - B)
                                      ---------
                                          A

                        where

                  "X" = the number of shares of Common Stock which the
Warrantholder has then requested be issued to the Warrantholder

                  "Y" = the total number of shares of Common Stock covered by
this Warrant which the Warrantholder has surrendered at such time for cash-less
exercise

                  "A" = the "Fair Market Value" of one share of Common Stock as

         Section 19. Call Provision. Notwithstanding any other provision
contained herein to the contrary, in the event that the closing bid price of a
share of Common Stock as traded on Nasdaq (or such other exchange as the Common
Stock may then be listed) exceeds 150% of the Warrant Price for twenty (20)
consecutive trading sessions and all of the Warrant Shares issuable hereunder
are registered pursuant to an effective Registration Statement (as defined in
the Registration Rights Agreement), the Company, upon ten (10) business days
prior written notice (the "Notice Period"), following such twenty (20) day
period, to the Warrantholder, may demand that the Warrantholder exercise its
rights with regard to all Warrant Shares and the


                                       10

Warrantholder must exercise its rights prior to the expiration of the Notice
Period or if such exercise is not made or if only a partial exercise is made,
