NEITHER THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE
HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM

ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR

                          COMMON STOCK PURCHASE WARRANT

                  To Purchase 22,000 Shares of Common Stock of

                           BIO-KEY INTERNATIONAL, INC.

          THIS COMMON STOCK PURCHASE WARRANT (the "WARRANT") CERTIFIES that, for
value received, David Moss (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 of issuance of this Warrant (the "INITIAL
EXERCISE DATE") and on or prior to the five year anniversary of the Initial
Exercise Date (the "TERMINATION DATE") but not thereafter, to subscribe for and
purchase from Bio-Key International, Inc., a Minnesota corporation (the
"COMPANY"), up to 22,000 shares (the "WARRANT SHARES") of Common Stock, par
value $0.01 per share, of the Company (the "COMMON Stock"). The purchase price
of one share of Common Stock (the "EXERCISE PRICE") under this Warrant shall be
$1.35, subject to adjustment hereunder.

          1.   TITLE TO WARRANT. Prior to the Termination Date and subject to
compliance with applicable laws and Section 7 of this Warrant, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or
agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed. The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.

          2.   AUTHORIZATION OF SHARES. The Company covenants that all Warrant
Shares 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

                                        1
<Page>

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 on or before the Termination Date by delivery to the Company of a
     duly executed facsimile copy of the Notice of Exercise Form annexed hereto
     (or such other office or agency of the Company as it may designate by
     notice in writing to the registered Holder at the address of such Holder
     appearing on the books of the Company); provided, however, within 5 Trading
     Days of the date said Notice of Exercise is delivered to the Company, the
     Holder shall have surrendered this Warrant to the Company and the Company
     shall have received payment of the aggregate Exercise Price of the shares
     thereby purchased by wire transfer or cashier's check drawn on a United
     States bank. Certificates for shares purchased hereunder shall be delivered
     to the Holder within 3 Trading Days from the delivery to the Company of the
     Notice of Exercise Form, surrender of this Warrant and payment of the
     aggregate Exercise Price as set forth above ("WARRANT SHARE DELIVERY
     DATE"). This Warrant shall be deemed to have been exercised on the date the
     Exercise Price is received by the Company. The Warrant Shares 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 the Holder, if any, pursuant to Section 5 prior to the issuance of
     such shares, have been paid. If the Company fails to deliver to the Holder
     a certificate or certificates representing the Warrant Shares pursuant to
     this Section 3(a) by the Warrant Share Delivery Date, then the Holder will
     have the right to rescind such exercise. In addition to any other rights
     available to the Holder, if the Company fails to deliver to the Holder a
     certificate or certificates representing the Warrant Shares pursuant to an
     exercise by the Warrant Share Delivery Date, and if after such day the
     Holder is required by its broker to purchase (in an open market transaction
     or otherwise) shares of Common Stock to deliver in satisfaction of a sale
     by the Holder of the Warrant Shares which the Holder anticipated receiving
     upon such exercise (a "BUY-IN"), then the Company shall (1) pay in cash to
     the Holder the amount by which (x) the Holder's total purchase price
     (including brokerage commissions, if any) for the shares of Common Stock so
     purchased exceeds (y) the amount obtained by multiplying (A) the number of
     Warrant Shares that the Company was required to deliver to the Holder in
     connection with the exercise at issue times (B) the price at which the sell
     order giving rise to such purchase obligation was executed, and (2) at the
     option of the Holder, either reinstate the portion of the Warrant and
     equivalent number of Warrant Shares for which such exercise was not honored
     or deliver to the Holder the number of shares of Common Stock that would
     have been issued had the Company timely complied with its exercise and
     delivery obligations hereunder. For example, if the Holder purchases Common
     Stock having a total purchase price of $11,000 to cover a Buy-In with
     respect to an attempted exercise of shares of Common Stock with an
     aggregate sale price giving rise to such purchase obligation of $10,000,
     under clause (1) of the immediately preceding sentence the Company shall be
     required to pay the Holder $1,000. The Holder shall provide the Company
     written notice indicating

                                        2
<Page>

     the amounts payable to the Holder in respect of the Buy-In, together with
     applicable confirmations and other evidence reasonably requested by the
     Company. Nothing herein shall limit a Holder's right to pursue any other
     remedies available to it hereunder, at law or in equity including, without
     limitation, a decree of specific performance and/or injunctive relief with
     respect to the Company's failure to timely deliver certificates
     representing shares of Common Stock upon exercise of the Warrant as
     required pursuant to the terms hereof.

                    (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 Warrant Shares called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant.

                    (c) The Holder shall not have the right to exercise any
     portion of this Warrant, pursuant to Section 3(a) or otherwise, to the
     extent that after giving effect to such issuance after exercise, the Holder
     (together with the Holder's affiliates), as set forth on the applicable
     Notice of Exercise, would beneficially own in excess of 4.99% of the number
     of shares of the Common Stock outstanding immediately after giving effect
     to such issuance. For purposes of the foregoing sentence, the number of
     shares of Common Stock beneficially owned by the Holder and its affiliates
     shall include the number of shares of Common Stock issuable upon exercise
     of this Warrant with respect to which the determination of such sentence is
     being made, but shall exclude the number of shares of Common Stock which
     would be issuable upon (A) exercise of the remaining, nonexercised portion
     of this Warrant beneficially owned by the Holder or any of its affiliates
     and (B) exercise or conversion of the unexercised or nonconverted portion
     of any other securities of the Company (including, without limitation, any
     other Warrants) subject to a limitation on conversion or exercise analogous
     to the limitation contained herein beneficially owned by the Holder or any
     of its affiliates. Except as set forth in the preceding sentence, for
     purposes of this Section 3(c), beneficial ownership shall be calculated in
     accordance with Section 13(d) of the Exchange Act, it being acknowledged by
     Holder that the Company is not representing to Holder that such calculation
     is in compliance with Section 13(d) of the Exchange Act and Holder is
     solely responsible for any schedules required to be filed in accordance
     therewith. To the extent that the limitation contained in this Section 3(c)
     applies, the determination of whether this Warrant is exercisable (in
     relation to other securities owned by the Holder) and of which a portion of
     this Warrant is exercisable shall be in the sole discretion of such Holder,
     and the submission of a Notice of Exercise shall be deemed to be such
     Holder's determination of whether this Warrant is exercisable (in relation
     to other securities owned by such Holder) and of which portion of this
     Warrant is exercisable, in each case subject to such aggregate percentage
     limitation, and the Company shall have no obligation to verify or confirm
     the accuracy of such determination. For purposes of this Section 3(c), in
     determining the number of outstanding shares of Common Stock, the Holder
     may rely on the number of outstanding shares of Common Stock as reflected
     in (x) the Company's most recent Form 10-Q or Form 10-K, as the case may
     be, (y) a more recent public announcement by the Company or (z) any other
     notice by the Company or the Company's Transfer Agent setting forth the
     number of shares of Common Stock

                                        3
<Page>

     outstanding. Upon the written or oral request of the Holder, the Company
     shall within two Trading Days confirm orally and in writing to the Holder
     the number of shares of Common Stock then outstanding. In any case, the
     number of outstanding shares of Common Stock shall be determined after
     giving effect to the conversion or exercise of securities of the Company,
     including this Warrant, by the Holder or its affiliates since the date as
     of which such number of outstanding shares of Common Stock was reported.

                    (d) This Warrant may also be exercised at such time by means
     of a "cashless exercise" in which the Holder shall be entitled to receive a
     certificate for the number of Warrant Shares equal to the quotient obtained
     by dividing [(A-B) x (X)] by (A), where:

          (A) = the Closing Price on the Trading Day immediately preceding the
                date of such election;

          (B) = the Exercise Price of this Warrant, as adjusted; and

          (X) = the number of Warrant Shares issuable upon exercise of this
                Warrant in accordance with the terms of this Warrant by means of
                a cash exercise rather than a cashless exercise.

          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 such fraction multiplied by
the Closing Price on the Trading Day.

          5.   CHARGES, TAXES AND EXPENSES. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder, or any subsequent holder, for
any issue or transfer tax or other incidental expense in respect of the issuance
of such certificate, all of which taxes and expenses shall be paid by the
Company, and such certificates shall be issued in the name of the Holder or in
such name or names as may be directed by the Holder.

          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, pursuant to the terms hereof.

          7.   TRANSFER, DIVISION AND COMBINATION.

                    (a) Subject to compliance with any applicable securities
     laws and the conditions set forth in Sections 1 and 7(e) hereof, this
     Warrant and all rights hereunder are transferable, in whole or in part,
     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 the 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

                                        4
<Page>

     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
     Warrant Shares 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 the Holder or its agent or
     attorney. Subject to compliance with Section 7(a), as to any transfer which
     may be involved in such division or combination, the Company shall execute
     and deliver a new Warrant or Warrants in exchange for the Warrant or
     Warrants to be divided or combined in accordance with such notice.

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

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

                    (e) If, at the time of the surrender of this Warrant in
     connection with any transfer of this Warrant, the transfer of this Warrant
     shall not be registered pursuant to an effective registration statement
     under the Securities Act and under applicable state securities or blue sky
     laws, the Company may require, as a condition of allowing such transfer (i)
     that the Holder or transferee of this Warrant, as the case may be, furnish
     to the Company a written opinion of counsel (which opinion shall be in
     form, substance and scope customary for opinions of counsel in comparable
     transactions) to the effect that such transfer may be made without
     registration under the Securities Act and under applicable state securities
     or blue sky laws, (ii) that the holder or transferee execute and deliver to
     the Company an investment letter in form and substance acceptable to the
     Company and (iii) that the transferee be an "accredited investor" as
     defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8) promulgated
     under the Securities Act or a qualified institutional buyer as defined in
     Rule 144A(a) under the Securities Act.

          8.   NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
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 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, in
the case of the Warrant, 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

                                        5
<Page>

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. 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, (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 shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which it 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 shall thereafter be entitled to purchase the
number of Warrant Shares or other securities resulting from such adjustment at
an Exercise Price per Warrant Share or other security obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of
the Company that are purchasable pursuant hereto immediately after 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.

          12.  REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, 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 its property, assets or business to
another corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation 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 the Holder shall have the right thereafter to receive, at the option of the
Holder, (a) 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, reclassification, 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 or (b) cash equal to the value of
this Warrant as determined in accordance with the Black Scholes

                                        6
<Page>

option pricing formula. In case of any such reorganization, reclassification,
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 Warrant Shares for which
this Warrant is exercisable which shall be as nearly equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "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 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

          13.  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.

          14.  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 give notice thereof to the Holder, which notice shall state 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.

          15.  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;

                                        7
<Page>

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
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 Warrant Shares 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 17(d).

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

          Except and to the extent as waived or consented to by the Holder, 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 as set forth in this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company will (a) not increase the par value of any Warrant Shares 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
Warrant Shares 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 Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall

                                        8
<Page>

obtain all such authorizations or exemptions thereof, or consents thereto, as
may be necessary from any public regulatory body or bodies having jurisdiction
thereof.

          17.  MISCELLANEOUS.

                    (a) GOVERNING LAW. All questions concerning the
     construction, validity, enforcement and interpretation of this Warrant
     shall be determined in accordance with the laws of the State of New York,
     without giving effect to its conflicts of laws principles or rules. The
     Company and the Holder agree that any dispute concerning this Warrant shall
     be resolved through binding arbitration before the NASD pursuant to its
     arbitration rules.

                    (b) RESTRICTIONS. The Holder 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 and knowingly fails to
     comply with any provision of this Warrant, which results in any material
     damages to the Holder, the Company shall pay to Holder such amounts as
     shall be sufficient to cover any costs and expenses including, but not
     limited to, reasonable attorneys' fees, including those of appellate
     proceedings, incurred by Holder in collecting any amounts due pursuant
     hereto or in otherwise enforcing any of its rights, powers or remedies
     hereunder.

                    (d) NOTICES. Any notice, request or other document required
     or permitted to be given or delivered to the Holder 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 any affirmative action by Holder to exercise this Warrant or
     purchase Warrant Shares, and no enumeration herein of the rights or
     privileges of Holder, 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

                                        9
<Page>

     from time to time of this Warrant and shall be enforceable by any such
     Holder or holder of Warrant Shares.

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

                    (i) 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.

                    (j) 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.

                    (k) INTEGRATION. This Warrant constitutes the entire
     understanding and agreement between the Company and the Holder with respect
     to the subject matter hereof and there are no agreements or understandings
     with respect hereto which are not contained in this Warrant.

HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM

ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN

REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE

                          COMMON STOCK PURCHASE WARRANT

                  To Purchase 22,000 Shares of Common Stock of

                           BIO-KEY INTERNATIONAL, INC.

          THIS COMMON STOCK PURCHASE WARRANT (the "WARRANT") CERTIFIES that, for
value received, Patrick Gaynes (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 of issuance of this Warrant (the "INITIAL
EXERCISE DATE") and on or prior to the five year anniversary of the Initial
Exercise Date (the "TERMINATION DATE") but not thereafter, to subscribe for and
purchase from Bio-Key International, Inc., a Minnesota corporation (the
"COMPANY"), up to 22,000 shares (the "WARRANT SHARES") of Common Stock, par
value $0.01 per share, of the Company (the "COMMON STOCK"). The purchase price
of one share of Common Stock (the "EXERCISE PRICE") under this Warrant shall be
$1.35, subject to adjustment hereunder.

          1. TITLE TO WARRANT. Prior to the Termination Date and subject to
compliance with applicable laws and Section 7 of this Warrant, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or
agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed. The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.

          2. AUTHORIZATION OF SHARES. The Company covenants that all Warrant
Shares 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

                                        1
<Page>

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
     on or before the Termination Date by delivery to the Company of a duly
     executed facsimile copy of the Notice of Exercise Form annexed hereto (or
     such other office or agency of the Company as it may designate by notice in
     writing to the registered Holder at the address of such Holder appearing on
     the books of the Company); provided, however, within 5 Trading Days of the
     date said Notice of Exercise is delivered to the Company, the Holder shall
     have surrendered this Warrant to the Company and the Company shall have
     received payment of the aggregate Exercise Price of the shares thereby
     purchased by wire transfer or cashier's check drawn on a United States
     bank. Certificates for shares purchased hereunder shall be delivered to the
     Holder within 3 Trading Days from the delivery to the Company of the Notice
     of Exercise Form, surrender of this Warrant and payment of the aggregate
     Exercise Price as set forth above ("WARRANT SHARE DELIVERY DATE"). This
     Warrant shall be deemed to have been exercised on the date the Exercise
     Price is received by the Company. The Warrant Shares 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
     the Holder, if any, pursuant to Section 5 prior to the issuance of such
     shares, have been paid. If the Company fails to deliver to the Holder a
     certificate or certificates representing the Warrant Shares pursuant to
     this Section 3(a) by the Warrant Share Delivery Date, then the Holder will
     have the right to rescind such exercise. In addition to any other rights
     available to the Holder, if the Company fails to deliver to the Holder a
     certificate or certificates representing the Warrant Shares pursuant to an
     exercise by the Warrant Share Delivery Date, and if after such day the
     Holder is required by its broker to purchase (in an open market transaction
     or otherwise) shares of Common Stock to deliver in satisfaction of a sale
     by the Holder of the Warrant Shares which the Holder anticipated receiving
     upon such exercise (a "BUY-IN"), then the Company shall (1) pay in cash to
     the Holder the amount by which (x) the Holder's total purchase price
     (including brokerage commissions, if any) for the shares of Common Stock so
     purchased exceeds (y) the amount obtained by multiplying (A) the number of
     Warrant Shares that the Company was required to deliver to the Holder in
     connection with the exercise at issue times (B) the price at which the sell
     order giving rise to such purchase obligation was executed, and (2) at the
     option of the Holder, either reinstate the portion of the Warrant and
     equivalent number of Warrant Shares for which such exercise was not honored
     or deliver to the Holder the number of shares of Common Stock that would
     have been issued had the Company timely complied with its exercise and
     delivery obligations hereunder. For example, if the Holder purchases Common
     Stock having a total purchase price of $11,000 to cover a Buy-In with
     respect to an attempted exercise of shares of Common Stock with an
     aggregate sale price giving rise to such purchase obligation of $10,000,
     under clause (1) of the immediately preceding sentence the Company shall be
     required to pay the Holder $1,000. The Holder shall provide the Company
     written notice indicating

                                        2
<Page>

     the amounts payable to the Holder in respect of the Buy-In, together with
     applicable confirmations and other evidence reasonably requested by the
     Company. Nothing herein shall limit a Holder's right to pursue any other
     remedies available to it hereunder, at law or in equity including, without
     limitation, a decree of specific performance and/or injunctive relief with
     respect to the Company's failure to timely deliver certificates
     representing shares of Common Stock upon exercise of the Warrant as
     required pursuant to the terms hereof.

               (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 Warrant Shares called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant.

               (c) The Holder shall not have the right to exercise any portion
     of this Warrant, pursuant to Section 3(a) or otherwise, to the extent that
     after giving effect to such issuance after exercise, the Holder (together
     with the Holder's affiliates), as set forth on the applicable Notice of
     Exercise, would beneficially own in excess of 4.99% of the number of shares
     of the Common Stock outstanding immediately after giving effect to such
     issuance. For purposes of the foregoing sentence, the number of shares of
     Common Stock beneficially owned by the Holder and its affiliates shall
     include the number of shares of Common Stock issuable upon exercise of this
     Warrant with respect to which the determination of such sentence is being
     made, but shall exclude the number of shares of Common Stock which would be
     issuable upon (A) exercise of the remaining, nonexercised portion of this
     Warrant beneficially owned by the Holder or any of its affiliates and (B)
     exercise or conversion of the unexercised or nonconverted portion of any
     other securities of the Company (including, without limitation, any other
     Warrants) subject to a limitation on conversion or exercise analogous to
     the limitation contained herein beneficially owned by the Holder or any of
     its affiliates. Except as set forth in the preceding sentence, for purposes
     of this Section 3(c), beneficial ownership shall be calculated in
     accordance with Section 13(d) of the Exchange Act, it being acknowledged by
     Holder that the Company is not representing to Holder that such calculation
     is in compliance with Section 13(d) of the Exchange Act and Holder is
     solely responsible for any schedules required to be filed in accordance
     therewith. To the extent that the limitation contained in this Section 3(c)
     applies, the determination of whether this Warrant is exercisable (in
     relation to other securities owned by the Holder) and of which a portion of
     this Warrant is exercisable shall be in the sole discretion of such Holder,
     and the submission of a Notice of Exercise shall be deemed to be such
     Holder's determination of whether this Warrant is exercisable (in relation
     to other securities owned by such Holder) and of which portion of this
     Warrant is exercisable, in each case subject to such aggregate percentage
     limitation, and the Company shall have no obligation to verify or confirm
     the accuracy of such determination. For purposes of this Section 3(c), in
     determining the number of outstanding shares of Common Stock, the Holder
     may rely on the number of outstanding shares of Common Stock as reflected
     in (x) the Company's most recent Form 10-Q or Form 10-K, as the case may
     be, (y) a more recent public announcement by the Company or (z) any other
     notice by the Company or the Company's Transfer Agent setting forth the
     number of shares of Common Stock

                                        3
<Page>

     outstanding. Upon the written or oral request of the Holder, the Company
     shall within two Trading Days confirm orally and in writing to the Holder
     the number of shares of Common Stock then outstanding. In any case, the
     number of outstanding shares of Common Stock shall be determined after
     giving effect to the conversion or exercise of securities of the Company,
     including this Warrant, by the Holder or its affiliates since the date as
     of which such number of outstanding shares of Common Stock was reported.

               (d) This Warrant may also be exercised at such time by means of a
     "cashless exercise" in which the Holder shall be entitled to receive a
     certificate for the number of Warrant Shares equal to the quotient obtained
     by dividing [(A-B) x (X)] by (A), where:

          (A) = the Closing Price on the Trading Day immediately preceding the
                date of such election;

          (B) = the Exercise Price of this Warrant, as adjusted; and

          (X) = the number of Warrant Shares issuable upon exercise of this
                Warrant in accordance with the terms of this Warrant by means of
                a cash exercise rather than a cashless exercise.

          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 such fraction multiplied by
the Closing Price on the Trading Day.

          5. CHARGES, TAXES AND EXPENSES. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder, or any subsequent holder, for
any issue or transfer tax or other incidental expense in respect of the issuance
of such certificate, all of which taxes and expenses shall be paid by the
Company, and such certificates shall be issued in the name of the Holder or in
such name or names as may be directed by the Holder.

          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,
pursuant to the terms hereof.

          7. TRANSFER, DIVISION AND COMBINATION.

               (a) Subject to compliance with any applicable securities laws and
     the conditions set forth in Sections 1 and 7(e) hereof, this Warrant and
     all rights hereunder are transferable, in whole or in part, 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 the 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

                                        4
<Page>

     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
     Warrant Shares 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 the Holder or its agent or attorney.
     Subject to compliance with Section 7(a), as to any transfer which may be
     involved in such division or combination, the Company shall execute and
     deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
     to be divided or combined in accordance with such notice.

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

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

               (e) If, at the time of the surrender of this Warrant in
     connection with any transfer of this Warrant, the transfer of this Warrant
     shall not be registered pursuant to an effective registration statement
     under the Securities Act and under applicable state securities or blue sky
     laws, the Company may require, as a condition of allowing such transfer (i)
     that the Holder or transferee of this Warrant, as the case may be, furnish
     to the Company a written opinion of counsel (which opinion shall be in
     form, substance and scope customary for opinions of counsel in comparable
     transactions) to the effect that such transfer may be made without
     registration under the Securities Act and under applicable state securities
     or blue sky laws, (ii) that the holder or transferee execute and deliver to
     the Company an investment letter in form and substance acceptable to the
     Company and (iii) that the transferee be an "accredited investor" as
     defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8) promulgated
     under the Securities Act or a qualified institutional buyer as defined in
     Rule 144A(a) under the Securities Act.

          8. NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
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 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, in
the case of the Warrant, 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

                                        5
<Page>

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. 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, (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 shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which it 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 shall thereafter be entitled to purchase the
number of Warrant Shares or other securities resulting from such adjustment at
an Exercise Price per Warrant Share or other security obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of
the Company that are purchasable pursuant hereto immediately after 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.

          12. REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, 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 its property, assets or business to
another corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation 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 the Holder shall have the right thereafter to receive, at the option of the
Holder, (a) 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, reclassification, 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 or (b) cash equal to the value of
this Warrant as determined in accordance with the Black Scholes

                                        6
<Page>

option pricing formula. In case of any such reorganization, reclassification,
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 Warrant Shares for which
this Warrant is exercisable which shall be as nearly equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "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 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

          13. 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.

          14. 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 give notice thereof to the Holder, which notice shall state 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.

          15. 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;

                                        7
<Page>

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
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 Warrant Shares 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 17(d).

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

          Except and to the extent as waived or consented to by the Holder, 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 as set forth in this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company will (a) not increase the par value of any Warrant Shares 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
Warrant Shares 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 Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall

                                        8
<Page>

obtain all such authorizations or exemptions thereof, or consents thereto, as
may be necessary from any public regulatory body or bodies having jurisdiction
thereof.

          17. MISCELLANEOUS.

               (a) GOVERNING LAW. All questions concerning the construction,
     validity, enforcement and interpretation of this Warrant shall be
     determined in accordance with the laws of the State of New York, without
     giving effect to its conflicts of laws principles or rules. The Company and
     the Holder agree that any dispute concerning this Warrant shall be resolved
     through binding arbitration before the NASD pursuant to its arbitration
     rules.

               (b) RESTRICTIONS. The Holder 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 and knowingly fails to comply with any
     provision of this Warrant, which results in any material damages to the
     Holder, the Company shall pay to Holder such amounts as shall be sufficient
     to cover any costs and expenses including, but not limited to, reasonable
     attorneys' fees, including those of appellate proceedings, incurred by
     Holder in collecting any amounts due pursuant hereto or in otherwise
     enforcing any of its rights, powers or remedies hereunder.

               (d) NOTICES. Any notice, request or other document required or
     permitted to be given or delivered to the Holder 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 any affirmative action by Holder to exercise this Warrant or purchase
     Warrant Shares, and no enumeration herein of the rights or privileges of
     Holder, 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

                                        9
<Page>

     from time to time of this Warrant and shall be enforceable by any such
     Holder or holder of Warrant Shares.

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

               (i) 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.

               (j) 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.

               (k) INTEGRATION. This Warrant constitutes the entire
     understanding and agreement between the Company and the Holder with respect
     to the subject matter hereof and there are no agreements or understandings
     with respect hereto which are not contained in this Warrant.

                              ********************
