                          COMMON STOCK PURCHASE WARRANT

                                ATS MEDICAL, INC.

Warrant Shares: [_______               Initial Exercise Date: September 17, 2007

          THIS COMMON STOCK PURCHASE WARRANT (the "Warrant") certifies that, for
value received, _____________ (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 181 days after the date hereof (the "Initial Exercise
Date") and on or prior to the close of business on the fifth year anniversary of
the Initial Exercise Date (the "Termination Date") but not thereafter, to
subscribe for and purchase from ATS Medical, Inc., a Minnesota corporation (the
"Company"), up to ______ shares (the "Warrant Shares") of Common Stock. The
purchase price of one share of Common Stock under this Warrant shall be equal to
the Exercise Price, as defined in Section 2(b).

     Section 1. Definitions. Capitalized terms used and not otherwise defined
herein shall have the meanings set forth in that certain Securities Purchase
Agreement (the "Purchase Agreement"), dated March 15, 2007, among the Company
and the purchasers signatory thereto.

     Section 2. Exercise.

          a) Exercise of Warrant. Exercise of the purchase rights represented by
     this Warrant may be made, in whole or in part, 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


                                        1

<PAGE>

     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); and, within 3 Trading Days of the date said
     Notice of Exercise is delivered to the Company, 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. Notwithstanding anything herein to the contrary, the Holder shall not
     be required to physically surrender this Warrant to the Company until the
     Holder has purchased all of the Warrant Shares available hereunder and the
     Warrant has been exercised in full, in which case, the Holder shall
     surrender this Warrant to the Company for cancellation within 3 Trading
     Days of the date the final Notice of Exercise is delivered to the Company.
     Partial exercises of this Warrant resulting in purchases of a portion of
     the total number of Warrant Shares available hereunder shall have the
     effect of lowering the outstanding number of Warrant Shares purchasable
     hereunder in an amount equal to the applicable number of Warrant Shares
     purchased. The Holder and the Company shall maintain records showing the
     number of Warrant Shares purchased and the date of such purchases. The
     Company shall deliver any objection to any Notice of Exercise Form within 1
     Business Day of receipt of such notice. In the event of any dispute or
     discrepancy, the records of the Holder shall be controlling and
     determinative in the absence of manifest error. THE HOLDER AND ANY
     ASSIGNEE, BY ACCEPTANCE OF THIS WARRANT, ACKNOWLEDGE AND AGREE THAT, BY
     REASON OF THE PROVISIONS OF THIS PARAGRAPH, FOLLOWING THE PURCHASE OF A
     PORTION OF THE WARRANT SHARES HEREUNDER, THE NUMBER OF WARRANT SHARES
     AVAILABLE FOR PURCHASE HEREUNDER AT ANY GIVEN TIME MAY BE LESS THAN THE
     AMOUNT STATED ON THE FACE HEREOF.

          b) Exercise Price. The exercise price per share of the Common Stock
     under this Warrant shall be $2.40, subject to adjustment hereunder (the
     "Exercise Price").

          c) Cashless Exercise. If at any time after the later of (i) the
     Initial Exercise Date or (ii) the Effectiveness Date of the Initial
     Registration Statement, there is no effective Registration Statement
     registering, or no current prospectus available for, the resale of the
     Warrant Shares by the Holder, then 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)] by (A), where:

          (A) = the VWAP 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.

          d) Exercise Limitations.

          i.   Holder's Restrictions. The Company shall not effect any exercise
               of this Warrant, and a Holder shall not have the right to
               exercise any portion of this Warrant, pursuant to Section 2 or
               otherwise, to the extent that after giving effect to such
               issuance after exercise as set forth on the applicable Notice of
               Exercise, such Holder (together with such Holder's Affiliates,
               and any other person or entity acting as a group together with
               such Holder or any of such Holder's Affiliates), would
               beneficially own in excess of the Beneficial Ownership Limitation
               (as defined below). For purposes of the foregoing sentence, the
               number of shares of Common Stock beneficially owned by such
               Holder and its Affiliates shall include the number of shares of
               Common Stock issuable upon exercise of this Warrant with respect
               to which such determination 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 such 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 Common Stock Equivalents) subject
               to a limitation on conversion or exercise analogous to the
               limitation contained herein beneficially owned by such Holder or
               any of its affiliates. Except as set forth in the preceding
               sentence, for purposes of this Section 2(d)(i), beneficial
               ownership shall be calculated in accordance with Section 13(d) of
               the Exchange Act and the rules and regulations promulgated
               thereunder, it being acknowledged by the Holder that the Company
               is not representing to such Holder that such calculation is in
               compliance with Section 13(d) of the Exchange Act and such Holder
               is solely responsible for any schedules required to be filed in
               accordance therewith. To the extent that the limitation contained
               in this Section 2(d)(i) applies, the determination of whether
               this Warrant is exercisable (in relation to other securities
               owned by such Holder together with any Affiliates) and of which
               portion of this Warrant is exercisable shall be in the sole
               discretion of the Holder, and the submission of a Notice of
               Exercise shall be deemed to be the Holder's determination of
               whether this Warrant is exercisable (in relation to other
               securities owned by such Holder together with any Affiliates) and
               of which portion of this Warrant is exercisable, in each case
               subject the Beneficial Ownership Limitation, and the Company
               shall have no obligation to verify or confirm the accuracy of
               such determination. In addition, a determination as to any group
               status as contemplated above shall be determined in accordance
               with Section 13(d) of the Exchange Act and the rules and
               regulations promulgated thereunder. For purposes of this Section
               2(d)(i), in determining the number of outstanding shares of
               Common Stock, a 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 outstanding. Upon


                                        3

<PAGE>


               the written or oral request of a Holder, the Company shall within
               two Trading Days confirm orally and in writing to such 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 such Holder
               or its Affiliates since the date as of which such number of
               outstanding shares of Common Stock was reported. The "Beneficial
               Ownership Limitation" shall be 4.9% of the number of shares of
               the Common Stock outstanding immediately after giving effect to
               the issuance of shares of Common Stock issuable upon exercise of
               this Warrant. The Beneficial Ownership Limitation provisions of
               this Section 2(d)(i) may be waived by such Holder, at the
               election of such Holder, upon not less than 61 days' prior notice
               to the Company to change the Beneficial Ownership Limitation to
               9.9% of the number of shares of the Common Stock outstanding
               immediately after giving effect to the issuance of shares of
               Common Stock upon exercise of this Warrant, and the provisions of
               this Section 2(d)(i) shall continue to apply. Upon such a change
               by a Holder of the Beneficial Ownership Limitation from such 4.9%
               limitation to such 9.9% limitation, the Beneficial Ownership
               Limitation may not be further waived by such Holder. The
               provisions of this paragraph shall be construed and implemented
               in a manner otherwise than in strict conformity with the terms of
               this Section 2(d)(i) to correct this paragraph (or any portion
               hereof) which may be defective or inconsistent with the intended
               Beneficial Ownership Limitation herein contained or to make
               changes or supplements necessary or desirable to properly give
               effect to such limitation. The limitations contained in this
               paragraph shall apply to a successor holder of this Warrant.

          ii.  RESERVED.

          e) Mechanics of Exercise.

                    i. Delivery of Certificates Upon Exercise. Certificates for
               shares purchased hereunder shall be transmitted by the transfer
               agent of the Company to the Holder by crediting the account of
               the Holder's prime broker with the Depository Trust Company
               through its Deposit Withdrawal Agent Commission ("DWAC") system
               if the Company is a participant in such system and there is an
               effective Registration Statement permitting the resale of the
               Warrant Shares by the Holder, and otherwise by physical delivery
               to the address specified by the Holder in the Notice of Exercise
               within 3 Trading Days from the delivery to the Company of the
               Notice of Exercise Form, surrender of this Warrant (if required)
               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


                                        4

<PAGE>
               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 (or by cashless exercise, if permitted) and
               all taxes required to be paid by the Holder, if any, pursuant to
               Section 2(e)(vi) prior to the issuance of such shares, have been
               paid. If the Company fails for any reason to deliver to the
               Holder certificates evidencing the Warrant Shares subject to a
               Notice of Exercise by the Warrant Share Delivery Date, the
               Company shall pay to such Holder, in cash, as liquidated damages
               and not as a penalty, for each $1,000 of Warrant Shares subject
               to such exercise (based on the VWAP of the Common Stock on the
               date of the applicable Notice of Exercise), $10 per Trading Day
               (increasing to $20 per Trading Day on the fifth Trading Day after
               such liquidated damages begin to accrue) for each Trading Day
               after such Warrant Share Delivery Date until such certificates
               are delivered.

                    ii. Delivery of New Warrants Upon Exercise. If this Warrant
               shall have been exercised in part, the Company shall, at the
               request of a Holder and upon surrender of this Warrant
               certificate, 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.

                    iii. Rescission Rights. If the Company fails to cause its
               transfer agent to transmit to the Holder a certificate or
               certificates representing the Warrant Shares pursuant to this
               Section 2(e)(ii) by the Warrant Share Delivery Date, then the
               Holder will have the right to rescind such exercise.

                    iv. Compensation for Buy-In on Failure to Timely Deliver
               Certificates Upon Exercise. In addition to any other rights
               available to the Holder, if the Company fails to cause its
               transfer agent to transmit to the Holder a certificate or
               certificates representing the Warrant Shares pursuant to an
               exercise on or before the Warrant Share Delivery Date, and if
               after such date the Holder is required by its broker to purchase
               (in an open market transaction or otherwise) or the Holder's
               brokerage firm otherwise purchases, 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


                                        5

<PAGE>
               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 the amounts
               payable to the Holder in respect of the Buy-In and, upon request
               of the Company, evidence of the amount of such loss. 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.

                    v. 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 at its election, either pay a cash
               adjustment in respect of such final fraction in an amount equal
               to such fraction multiplied by the Exercise Price or round up to
               the next whole share.

                    vi. Charges, Taxes and Expenses. Issuance of certificates
               for Warrant Shares shall be made without charge to the 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; provided, however, that
               in the event certificates for Warrant Shares are to be issued in
               a name other than the name of the Holder, this Warrant when
               surrendered for exercise shall be accompanied by the Assignment
               Form attached hereto duly executed by the Holder; and the Company
               may require, as a condition thereto, the payment of a sum
               sufficient to reimburse it for any transfer tax incidental
               thereto.

                    vii. 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.

     Section 3. Certain Adjustments.

          a) Stock Dividends and Splits. If the Company, at any time while this
     Warrant is outstanding: (A) pays a stock dividend or otherwise make a
     distribution or distributions on shares of its Common Stock or any other
     equity or equity equivalent


                                        6

<PAGE>

     securities payable in shares of Common Stock (which, for avoidance of
     doubt, shall not include any shares of Common Stock issued by the Company
     upon exercise of this Warrant), (B) subdivides outstanding shares of Common
     Stock into a larger number of shares, (C) combines (including by way of
     reverse stock split) outstanding shares of Common Stock into a smaller
     number of shares, or (D) issues by reclassification of shares of the Common
     Stock any shares of capital stock of the Company, then in each case the
     Exercise Price shall be multiplied by a fraction of which the numerator
     shall be the number of shares of Common Stock (excluding treasury shares,
     if any) outstanding immediately before such event and of which the
     denominator shall be the number of shares of Common Stock outstanding
     immediately after such event and the number of shares issuable upon
     exercise of this Warrant shall be proportionately adjusted such that the
     aggregate Exercise Price of this Warrant shall remain unchanged. Any
     adjustment made pursuant to this Section 3(a) shall become effective
     immediately after the record date for the determination of stockholders
     entitled to receive such dividend or distribution and shall become
     effective immediately after the effective date in the case of a
     subdivision, combination or re-classification.

          b) RESERVED.

          c) Subsequent Rights Offerings. If the Company, at any time while the
     Warrant is outstanding, shall issue rights, options or warrants to all
     holders of Common Stock (and not to Holders) entitling them to subscribe
     for or purchase shares of Common Stock at a price per share less than the
     VWAP at the record date mentioned below, then the Exercise Price shall be
     multiplied by a fraction, of which the denominator shall be the number of
     shares of the Common Stock outstanding on the date of issuance of such
     rights or warrants plus the number of additional shares of Common Stock
     offered for subscription or purchase, and of which the numerator shall be
     the number of shares of the Common Stock outstanding on the date of
     issuance of such rights or warrants plus the number of shares which the
     aggregate offering price of the total number of shares so offered (assuming
     receipt by the Company in full of all consideration payable upon exercise
     of such rights, options or warrants) would purchase at such VWAP. Such
     adjustment shall be made whenever such rights or warrants are issued, and
     shall become effective immediately after the record date for the
     determination of stockholders entitled to receive such rights, options or
     warrants.

          d) Pro Rata Distributions. If the Company, at any time while this
     Warrant is outstanding, shall distribute to all holders of Common Stock
     (and not to Holders of the Warrants) evidences of its indebtedness or
     assets (including cash and cash dividends) or rights or warrants to
     subscribe for or purchase any security other than the Common Stock (which
     shall be subject to Section 3(b)), then in each such case the Exercise
     Price shall be adjusted by multiplying the Exercise Price in effect
     immediately prior to the record date fixed for determination of
     stockholders entitled to receive such distribution by a fraction of which
     the denominator shall be the VWAP determined as of the record date
     mentioned above, and of which the numerator shall be such VWAP on such
     record date less the then per share fair market value at such record date
     of the portion of such assets or evidence of indebtedness so distributed
     applicable to one outstanding share of the Common Stock as determined by
     the Board of Directors in good faith. In either case the adjustments shall


                                        7

<PAGE>

     be described in a statement provided to the Holder of the portion of assets
     or evidences of indebtedness so distributed or such subscription rights
     applicable to one share of Common Stock. Such adjustment shall be made
     whenever any such distribution is made and shall become effective
     immediately after the record date mentioned above.

          e) Fundamental Transaction. If, at any time while this Warrant is
     outstanding, (A) the Company effects any merger or consolidation of the
     Company with or into another Person, (B) the Company effects any sale of
     all or substantially all of its assets in one or a series of related
     transactions, (C) any tender offer or exchange offer (whether by the
     Company or another Person) is completed pursuant to which holders of Common
     Stock are permitted to tender or exchange their shares for other
     securities, cash or property, or (D) the Company effects any
     reclassification of the Common Stock or any compulsory share exchange
     pursuant to which the Common Stock is effectively converted into or
     exchanged for other securities, cash or property (each "Fundamental
     Transaction"), then, upon any subsequent exercise of this Warrant, the
     Holder shall have the right to receive, for each Warrant Share that would
     have been issuable upon such exercise immediately prior to the occurrence
     of such Fundamental Transaction, the number of shares of Common Stock of
     the successor or acquiring corporation or of the Company, if it is the
     surviving corporation, and any additional consideration (the "Alternate
     Consideration") receivable as a result of such 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. For
     purposes of any such exercise, the determination of the Exercise Price
     shall be appropriately adjusted to apply to such Alternate Consideration
     based on the amount of Alternate Consideration issuable in respect of one
     share of Common Stock in such Fundamental Transaction, and the Company
     shall apportion the Exercise Price among the Alternate Consideration in a
     reasonable manner reflecting the relative value of any different components
     of the Alternate Consideration. If holders of Common Stock are given any
     choice as to the securities, cash or property to be received in a
     Fundamental Transaction, then the Holder shall be given the same choice as
     to the Alternate Consideration it receives upon any exercise of this
     Warrant following such Fundamental Transaction. To the extent necessary to
     effectuate the foregoing provisions, any successor to the Company or
     surviving entity in such Fundamental Transaction shall issue to the Holder
     a new warrant consistent with the foregoing provisions and evidencing the
     Holder's right to exercise such warrant into Alternate Consideration. The
     terms of any agreement pursuant to which a Fundamental Transaction is
     effected shall include terms requiring any such successor or surviving
     entity to comply with the provisions of this Section 3(e) and insuring that
     this Warrant (or any such replacement security) will be similarly adjusted
     upon any subsequent transaction analogous to a Fundamental Transaction.
     Notwithstanding anything to the contrary, in the event of a Fundamental
     Transaction that is (1) an all cash transaction, (2) a "Rule 13e-3
     transaction" as defined in Rule 13e-3 under the Securities Exchange Act of
     1934, as amended, or (3) a Fundamental Transaction involving a person or
     entity not traded on a national securities exchange, the Nasdaq Global
     Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, the
     Company or any successor entity shall pay at the Holder's option,
     exercisable at any time concurrently with or within 30 days after the
     consummation of the Fundamental Transaction, an amount of cash equal to the
     value of this Warrant as determined in accordance with the Black-


                                        8
<PAGE>

     Scholes option pricing formula using an expected volatility equal to the
     100 day historical price volatility obtained from the HVT function on
     Bloomberg L.P. as of the trading day immediately prior to the public
     announcement of the Fundamental Transaction.

          f) Calculations. All calculations under this Section 3 shall be made
     to the nearest cent or the nearest 1/100th of a share, as the case may be.
     For purposes of this Section 3, the number of shares of Common Stock deemed
     to be issued and outstanding as of a given date shall be the sum of the
     number of shares of Common Stock (excluding treasury shares, if any) issued
     and outstanding.

          g) RESERVED.

          h) Notice to Holder.

                    i. Adjustment to Exercise Price. Whenever the Exercise Price
               is adjusted pursuant to any provision of this Section 3, the
               Company shall promptly mail to the Holder a notice setting forth
               the Exercise Price after such adjustment and setting forth a
               brief statement of the facts requiring such adjustment. If the
               Company issues a variable rate security, despite the prohibition
               thereon in the Purchase Agreement, the Company shall be deemed to
               have issued Common Stock or Common Stock Equivalents at the
               lowest possible conversion or exercise price at which such
               securities may be converted or exercised in the case of a
               Variable Rate Transaction (as defined in the Purchase Agreement).

                    ii. Notice to Allow Exercise by Holder. If (A) the Company
               shall declare a dividend (or any other distribution in whatever
               form) on the Common Stock; (B) the Company shall declare a
               special nonrecurring cash dividend on or a redemption of the
               Common Stock; (C) the Company shall authorize the granting to all
               holders of the Common Stock rights or warrants to subscribe for
               or purchase any shares of capital stock of any class or of any
               rights; (D) the approval of any stockholders of the Company shall
               be required in connection with any reclassification of the Common
               Stock, any consolidation or merger to which the Company is a
               party, any sale or transfer of all or substantially all of the
               assets of the Company, of any compulsory share exchange whereby
               the Common Stock is converted into other securities, cash or
               property; (E) the Company shall authorize the voluntary or
               involuntary dissolution, liquidation or winding up of the affairs
               of the Company; then, in each case, the Company shall cause to be
               mailed to the Holder at its last address as it shall appear upon
               the Warrant Register of the Company, at least 20 calendar days
               prior to the applicable record or effective date hereinafter
               specified, a notice stating (x) the date on which a record is to
               be taken for the purpose of such dividend, distribution,
               redemption, rights or warrants, or if a record is not


                                       9

<PAGE>

               to be taken, the date as of which the holders of the Common Stock
               of record to be entitled to such dividend, distributions,
               redemption, rights or warrants are to be determined or (y) the
               date on which such reclassification, consolidation, merger, sale,
               transfer or share exchange is expected to become effective or
               close, and the date as of which it is expected that holders of
               the Common Stock of record shall be entitled to exchange their
               shares of the Common Stock for securities, cash or other property
               deliverable upon such reclassification, consolidation, merger,
               sale, transfer or share exchange; provided that the failure to
               mail such notice or any defect therein or in the mailing thereof
               shall not affect the validity of the corporate action required to
               be specified in such notice. The Holder is entitled to exercise
               this Warrant during the period commencing on the date of such
               notice to the effective date of the event triggering such notice.

     Section 4. Transfer of Warrant.

          a) Transferability. Subject to compliance with any applicable
     securities laws and the conditions set forth in Section 4(d) hereof and to
     the provisions of Section 4.1 of the Purchase Agreement, this Warrant and
     all rights hereunder (including, without limitation, any registration
     rights) are transferable, in whole or in part, upon surrender of this
     Warrant at the principal office of the Company or its designated agent,
     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 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) New Warrants. 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 4(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. All
     Warrants issued on transfers or exchanges shall be dated the original Issue
     Date and shall be identical with this Warrant except as to the number of
     Warrant Shares issuable pursuant thereto.

          c) Warrant Register. The Company shall register this Warrant, upon
     records to be maintained by the Company for that purpose (the "Warrant
     Register"), in the name of the record Holder hereof from time to time. The
     Company may deem and treat the registered Holder of this Warrant as the
     absolute owner hereof for the purpose of any


                                       10

<PAGE>

     exercise hereof or any distribution to the Holder, and for all other
     purposes, absent actual notice to the contrary.

          d) Transfer Restrictions. 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, that the Holder or transferee of this Warrant, as the case may
     be, comply with the provisions of Section 5.7 of the Purchase Agreement.

     Section 5. Miscellaneous.

          a) 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 as set forth in Section 2(e)(i).

          b) 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
     deliver a new Warrant or stock certificate of like tenor and dated as of
     such cancellation, in lieu of such Warrant or stock certificate.

          c) 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 not be a Business Day, then such action may be taken or such
     right may be exercised on the next succeeding Business Day.

          d) 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. 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


                                       11

<PAGE>

          duly authorized, validly issued, fully paid and nonassessable and free
          from all taxes, liens and charges created by the Company in respect of
          the issue thereof (other than taxes in respect of any transfer
          occurring contemporaneously with such issue).

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

          e) Jurisdiction. All questions concerning the construction, validity,
     enforcement and interpretation of this Warrant shall be determined in
     accordance with the provisions of the Purchase Agreement.

          f) 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.

          g) 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 the fact that 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.


                                       12

<PAGE>

          h) 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.

          i) Limitation of Liability. No provision hereof, in the absence of any
     affirmative action by Holder to exercise this Warrant to 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.

          j) 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 and not to assert the defense in any action for
     specific performance that a remedy at law would be adequate.

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

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

          m) 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.

          n) 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.
