                          COMMON STOCK PURCHASE WARRANT

                             TOWERSTREAM CORPORATION

Warrant Shares: _______                  Initial Exercise Date: January 18, 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 the date hereof (the "Initial Exercise Date") and on or
prior to the close of business on the five year anniversary of the Initial
Exercise Date (the "Termination Date") but not thereafter, to subscribe for and
purchase from Towerstream Corporation, a Delaware corporation (the "Company"),
up to ______ shares (the "Warrant Shares") of common stock, par value $.001 per
share, of the Company (the "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 January __, 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 other office or agency of the Company
     as it may designate by notice in writing to the

                                        1

     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 of
     immediately available funds. 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 2 Business Days of receipt of such notice.
     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 $_____[50% AT $4.00 AND 50% AT $6.00], subject
     to adjustment hereunder (the "Exercise Price").

          c) Cashless Exercise. If at any time after one year from the date of
     issuance of this Warrant 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.

          Notwithstanding anything herein to the contrary, on the Termination
     Date, this Warrant shall be automatically exercised via cashless exercise
     pursuant to this Section 2(c).

                                        2

          d) Exercise Limitations. 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(c) 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), as set forth on the
     applicable Notice of Exercise, 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 Debentures or Warrants) 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),
     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 a 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) 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 a portion of this
     Warrant is exercisable shall be in the sole discretion of a Holder, and the
     submission of a Notice of Exercise shall be deemed to be each 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 to such
     aggregate percentage 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), 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-QSB or Form 10-KSB, 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 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
     4.99% of the number of shares of the

                                        3

     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) 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 9.99% 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)
     shall continue to apply. Upon such a change by a Holder of the Beneficial
     Ownership Limitation from such 4.99% limitation to such 9.99% 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) 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.

          e) Mechanics of Exercise.

                    i. Authorization of Warrant 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 created by the Company in
               respect of the issue thereof (other than taxes in respect of any
               transfer occurring contemporaneously with such issue).

                    ii. 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 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 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)(vii) prior to the issuance of such shares, have been
               paid. If the Company fails for any reason to take all actions
               within the Company's

                                        4

               control required to cause there to be delivered 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), $5 per Trading Day for each
               Trading Day after the fourth Trading Day following such Warrant
               Share Delivery Date until such certificates are delivered.

                    iii. 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.

                    iv. 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)(iv) by the Warrant Share Delivery Date, then the
               Holder will have the right to rescind such exercise.

                    v. [RESERVED].

                    vi. 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.

                    vii. 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.

                                        5

                    viii. 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
          makes a distribution or distributions on shares of its Common Stock or
          any other equity or equity equivalent 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. 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) Subsequent Equity Sales. If the Company or any Subsidiary
          thereof, as applicable, at any time while the Debentures are
          outstanding, shall sell or grant any option to purchase, or sell or
          grant any right to reprice its securities, or otherwise dispose of or
          issue (or announce any offer, sale, grant or any option to purchase or
          other disposition) any Common Stock or Common Stock Equivalents
          entitling any Person to acquire shares of Common Stock, at an
          effective price per share less than $2.75 (subject to adjustment for
          forward and reverse stock splits, stock dividends, recapitalizations
          and the like) (such lower price, the "Base Share Price" and such
          issuances collectively, a "Dilutive Issuance") (if the holder of the
          Common Stock or Common Stock Equivalents so issued shall at any time,
          whether by operation of purchase price adjustments, reset provisions,
          floating conversion, exercise or exchange prices or otherwise, or due
          to warrants, options or rights per share which are issued in
          connection with such issuance, be entitled to receive shares of Common
          Stock at an effective price per share which is less than the Exercise
          Price, such issuance shall be deemed to have occurred for less than
          the Exercise Price on such date of the Dilutive Issuance), then the
          Exercise Price shall be reduced and only reduced to equal
          [__________(1). For clarity, the Exercise Price can only be adjusted
          downward pursuant to this Section 3(b) (if ___(2) of such Base Share
          Price is not less than the then Exercise Price immediately prior to
          such Dilutive Issuance, no

----------
(1)  145% of such Base Share Price as to the $4.00 warrants and 218% of such
     Base Share Price as to the $6.00 warrants.

(2)  145% as to $4 warrants and 218% as to $6 warrants

                                        6

          adjustment to the Exercise Price shall be made). By way of an example,
          if the Base Share Price in connection with a Dilutive Issuance is
          $2.00, the Exercise Price of this Warrant would be reduced to
          _____.(3) Such adjustment shall be made whenever such Common Stock or
          Common Stock Equivalents are issued. Notwithstanding the foregoing, no
          adjustments shall be made, paid or issued under this Section 3(b) in
          respect of an Exempt Issuance. The Company shall notify the Holder in
          writing, no later than the Trading Day following the issuance of any
          Common Stock or Common Stock Equivalents subject to this Section 3(b),
          indicating therein the applicable issuance price, or applicable reset
          price, exchange price, conversion price and other pricing terms (such
          notice the "Dilutive Issuance Notice"). For purposes of clarification,
          whether or not the Company provides a Dilutive Issuance Notice
          pursuant to this Section 3(b), upon the occurrence of any Dilutive
          Issuance, after the date of such Dilutive Issuance the Holder is
          entitled to receive a number of Warrant Shares based upon the Base
          Share Price regardless of whether the Holder accurately refers to the
          Base Share Price in the Notice of Exercise.

               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 prior to
          the Termination Date, 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 be described in a statement provided to the
          Holder of the portion of

----------
(3)  $2.90 as to the $4.00 warrants and $4.36 as to the $6.00 warrants.

                                        7

          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, 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

          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) Voluntary Adjustment By 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.

               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 enters into a Variable Rate
                    Transaction (as defined in the Purchase Agreement) 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.

                         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

                    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
                    20-day 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.

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

                                       10

          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 (i) 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, and (ii) the Holder or transferee execute and
     deliver to the Company an investment letter in form and substance
     acceptable to the Company, and (iii) 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) promulgated under the Securities Act.

     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)(ii).

          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

                                       11

          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 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

          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.
