HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
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 TO

                          COMMON STOCK PURCHASE WARRANT

                 To Purchase _________ Shares of Common Stock of

                               US DATAWORKS, INC.

            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 three year anniversary of the
Initial Exercise Date (the "Termination Date") but not thereafter, to subscribe
for and purchase from US Dataworks, Inc., a Nevada corporation (the "Company"),
up to ________ shares (the "Warrant Shares") of Common Stock, par value $0.0001
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 June 16, 2005, 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 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

                                       1
<PAGE>

      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.

            b) Exercise Price. The exercise price of the Common Stock under this
      Warrant shall be $0.812, 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 provided that there is no effective Registration Statement
      registering, or no current prospectus available for, the resale of the
      Warrant Shares by the Holder, this Warrant shall be automatically
      exercised via cashless exercise pursuant to this Section 2(c).

            d) Exercise Limitations.

                        i. Holder's Restrictions. 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, such Holder (together
                  with such 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 such 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 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 shares
                  of Warrants) subject to a limitation on conversion or exercise
                  analogous to the limitation contained herein beneficially
                  owned by such Holder or any

                                       2
<PAGE>

                  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, 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) 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) 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
                  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 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, and
                  the provisions of this Section 2(d) shall continue to apply
                  until such 61st day (or such later date, as determined by such
                  Holder, as may be specified in such notice of waiver).

                        ii. Trading Market Restrictions. If the Company has not
                  obtained Shareholder Approval (as defined below) if required
                  by the applicable rules and regulations of the Trading Market
                  (or any successor entity), then the Company may not issue upon
                  exercise of this Warrant a number of shares of Common Stock
                  which, when aggregated with any shares of Common Stock issued
                  upon prior exercise of this or any other Warrant issued
                  pursuant to the Purchase Agreement, would exceed 19.999% of
                  the number of shares of Common Stock outstanding on the
                  Trading Day immediately preceding the Closing Date (such
                  number of shares, the "Issuable Maximum"). If on any attempted
                  exercise of this Warrant, the issuance of Warrant Shares would
                  exceed the Issuable Maximum and the

                                       3
<PAGE>

                  Company shall not have previously obtained the vote of
                  shareholders (the "Shareholder Approval"), if any, as may be
                  required by the applicable rules and regulations of the
                  Trading Market (or any successor entity) to approve the
                  issuance of shares of Common Stock in excess of the Issuable
                  Maximum pursuant to the terms hereof, then the Company shall
                  issue to the Holder requesting a Warrant exercise such number
                  of Warrant Shares as may be issued below the Issuable Maximum
                  and, with respect to the remainder of the aggregate number of
                  Warrant Shares, this Warrant shall not be exercisable until
                  and unless Shareholder Approval has been obtained.

            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 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 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 2(e)(vii) prior to the
                  issuance of such shares, have been paid.

                        iii. Delivery of New Warrants Upon Exercise. 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.

                                       4

                        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. 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) 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 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.

                        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 pay a cash adjustment in respect
                  of such final fraction in an amount equal to such fraction
                  multiplied by the Exercise Price.

                                       5
<PAGE>

                        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.

                        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 make 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 pursuant to 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 this Warrant is outstanding,
      shall offer, sell, grant any option to purchase or offer, 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 the then Exercise Price (such lower price, the "Base Share
      Price" and such issuances collectively, a "Dilutive Issuance"), as
      adjusted hereunder (if the holder of the Common Stock or Common Stock
      Equivalents so issued shall at any time, whether by operation of purchase

                                       6
<PAGE>

      price adjustments, reset provisions, floating conversion, exercise or
      exchange prices or otherwise, or due to warrants, options or rights per
      share which is 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 the Base Share Price. 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,
      indicating therein the applicable issuance price, or of 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 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) 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 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.

            d) 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 (in any such case, a
      "Fundamental Transaction"), then, upon any subsequent exercise of this
      Warrant, the

                                       7
<PAGE>

      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, 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 any additional consideration (the "Alternate
      Consideration") 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) if the Company is
      acquired in an all cash transaction, cash equal to the value of this
      Warrant as determined in accordance with the Black-Scholes option pricing
      formula. 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(d) and
      insuring that this Warrant (or any such replacement security) will be
      similarly adjusted upon any subsequent transaction analogous to a
      Fundamental Transaction.

            e) 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.

            f) 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.

            g) Notice to Holders.

                        i. Adjustment to Exercise Price. Whenever the Exercise
                  Price is adjusted pursuant to this Section 3, the Company
                  shall promptly mail to each 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

                                       8
<PAGE>

                  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)
                  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 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 Sections 5(a) and 4(d)
      hereof and to the provisions of Section 4.1 of the Purchase Agreement,
      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

                                       9
<PAGE>

      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.

            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 (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.

      Section 5. Miscellaneous.

            a) Title to Warrant. Prior to the Termination Date and subject to
      compliance with applicable laws and Section 4 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.

                                       10
<PAGE>

            b) 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.

            c) 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.

            d) 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.

            e) 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

                                       11
<PAGE>

            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.

            f) 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.

            g) 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.

            h) 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.

            i) 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.

            j) 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.

            k) 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

                                       12
<PAGE>

      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.

            l) 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.

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

            n) 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.

            o) 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.

the Registrable Securities on such Filing Date for an offering to be made on a
continuous basis pursuant to Rule 415. The Registration Statement shall be on
Form S-3 (except if the Company is not then eligible to

                                        2

<PAGE>

register for resale the Registrable Securities on Form S-3, in which case such
registration shall be on another appropriate form in accordance herewith) and
shall contain (unless otherwise directed by the Holders) substantially the "Plan
of Distribution" attached hereto as Annex A. Subject to the terms of this
Agreement, the Company shall use its best efforts to cause a Registration
Statement to be declared effective under the Securities Act as promptly as
possible after the filing thereof, but in any event prior to the applicable
Effectiveness Date, and shall use its best efforts to keep such Registration
Statement continuously effective under the Securities Act until all Registrable
Securities covered by such Registration Statement have been sold or may be sold
without volume restrictions pursuant to Rule 144(k) as determined by the counsel
to the Company pursuant to a written opinion letter to such effect, addressed
and acceptable to the Company's transfer agent and the affected Holders (the
"Effectiveness Period"). The Company shall telephonically request effectiveness
of a Registration Statement as of 5:00 pm Eastern Time on a Trading Day. The
Company shall immediately notify the Holders via facsimile of the effectiveness
of a Registration Statement on the same Trading Day that the Company
telephonically confirms effectiveness with the Commission, which shall be the
date requested for effectiveness of a Registration Statement. The Company shall,
by 9:30 am Eastern Time on the Trading Day after the Effective Date (as defined
in the Purchase Agreement), file a Form 424(b)(5) with the Commission. Failure
to so notify the Holder within 1 Trading Day of such notification shall be
deemed an Event under Section 2(b).

            (b) If: (i) a Registration Statement is not filed on or prior to its
Filing Date (if the Company files a Registration Statement without affording the
Holders the opportunity to review and comment on the same as required by Section
3(a), the Company shall not be deemed to have satisfied this clause (i)), or
(ii) the Company fails to file with the Commission a request for acceleration in
accordance with Rule 461 promulgated under the Securities Act, within five
Trading Days of the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that a Registration Statement will not
be "reviewed," or not subject to further review, or (iii) prior to its
Effectiveness Date, the Company fails to file a pre-effective amendment and
otherwise respond in writing to comments made by the Commission in respect of
such Registration Statement within 10 calendar days after the receipt of
comments by or notice from the Commission that such amendment is required in
order for a Registration Statement to be declared effective, or (iv) a
Registration Statement filed or required to be filed hereunder is not declared
effective by the Commission by its Effectiveness Date, or (v) after the
Effectiveness Date, a Registration Statement ceases for any reason to remain
continuously effective as to all Registrable Securities for which it is required
to be effective, or the Holders are not permitted to utilize the Prospectus
therein to resell such Registrable Securities for 10 consecutive calendar days
but no more than an aggregate of 15 calendar days during any 12-month period
(which need not be consecutive Trading Days) (any such failure or breach being
referred to as an "Event", and for purposes of clause (i) or (iv) the date on
which such Event occurs, or for purposes of clause (ii) the date on which such
five Trading Day period is exceeded, or for purposes of clause (iii) the date
which such 10 calendar day period is exceeded, or for purposes of clause (v) the
date on which such 10 or 15 calendar day period, as applicable, is exceeded
being referred to as "Event Date"), then in addition to any other rights the
Holders may have hereunder or under applicable law, on each such Event Date and
on each monthly anniversary of each such Event Date (if the applicable Event
shall not have been cured by such date) until the applicable Event is cured, the
Company shall pay to each Holder an amount in

                                        3

<PAGE>

cash, as partial liquidated damages and not as a penalty, equal to 2.0% of the
aggregate purchase price paid by such Holder pursuant to the Purchase Agreement
for any Registrable Securities then held by such Holder. If the Company fails to
pay any partial liquidated damages pursuant to this Section in full within seven
days after the date payable, the Company will pay interest thereon at a rate of
18% per annum (or such lesser maximum amount that is permitted to be paid by
applicable law) to the Holder, accruing daily from the date such partial
liquidated damages are due until such amounts, plus all such interest thereon,
are paid in full. The partial liquidated damages pursuant to the terms hereof
shall apply on a daily pro-rata basis for any portion of a month prior to the
cure of an Event.

      3. Registration Procedures.

            In connection with the Company's registration obligations hereunder,
the Company shall:

            (a) Not less than five Trading Days prior to the filing of each
Registration Statement or any related Prospectus or any amendment or supplement
thereto (including any document that would be incorporated or deemed to be
incorporated therein by reference), the Company shall, (i) furnish to each
Holder copies of all such documents proposed to be filed, which documents (other
than those incorporated or deemed to be incorporated by reference) will be
subject to the review of such Holders, and (ii) cause its officers and
directors, counsel and independent certified public accountants to respond to
such inquiries as shall be necessary, in the reasonable opinion of respective
counsel to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file a Registration Statement or any such
Prospectus or any amendments or supplements thereto to which the Holders of a
majority of the Registrable Securities shall reasonably object in good faith,
provided that, the Company is notified of such objection in writing no later
than 5 Trading Days after the Holders have been so furnished copies of such
documents. Each Holder agrees to furnish to the Company a completed
Questionnaire in the form attached to this Agreement as Annex B (a "Selling
Shareholder Questionnaire") not less than two Trading Days prior to the Filing
Date or by the end of the fourth Trading Day following the date on which such
Holder receives draft materials in accordance with this Section.

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to a Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep a
Registration Statement continuously effective as to the applicable Registrable
Securities for the Effectiveness Period and prepare and file with the Commission
such additional Registration Statements in order to register for resale under
the Securities Act all of the Registrable Securities; (ii) cause the related
Prospectus to be amended or supplemented by any required Prospectus supplement
(subject to the terms of this Agreement), and as so supplemented or amended to
be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible
to any comments received from the Commission with respect to a Registration
Statement or any amendment thereto and as promptly as reasonably possible
provide the Holders true and complete copies of all correspondence from and to
the Commission relating to a Registration Statement; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange Act
with respect to the disposition of all Registrable Securities covered by a
Registration Statement during the applicable period in accordance

                                        4

<PAGE>

(subject to the terms of this Agreement) with the intended methods of
disposition by the Holders thereof set forth in such Registration Statement as
so amended or in such Prospectus as so supplemented.

            (c) Notify the Holders of Registrable Securities to be sold (which
notice shall, pursuant to clauses (ii) through (vi) hereof, be accompanied by an
instruction to suspend the use of the Prospectus until the requisite changes
have been made) as promptly as reasonably possible (and, in the case of (i)(A)
below, not less than five Trading Days prior to such filing) and (if requested
by any such Person) confirm such notice in writing no later than one Trading Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to a Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement (the Company shall provide true and complete copies
thereof and all written responses thereto to each of the Holders); and (C) with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to a
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission or any other federal or state governmental authority
of any stop order suspending the effectiveness of a Registration Statement
covering any or all of the Registrable Securities or the initiation of any
Proceedings for that purpose; (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; (v) of the occurrence of any event or passage of time that makes the
financial statements included in a Registration Statement ineligible for
inclusion therein or any statement made in a Registration Statement or
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires any revisions to a
Registration Statement, Prospectus or other documents so that, in the case of a
Registration Statement or the Prospectus, as the case may be, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading; and
(vi) the occurrence or existence of any pending corporate development with
respect to the Company that the Company believes may be material and that, in
the determination of the Company, makes it not in the best interest of the
Company to allow continued availability of a Registration Statement or
Prospectus; provided that any and all of such information shall remain
confidential to each Holder until such information otherwise becomes public,
unless disclosure by a Holder is required by law; provided, further,
notwithstanding each Holder's agreement to keep such information confidential,
the Holders make no acknowledgement that any such information is material,
non-public information.

            (d) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of a
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                                        5

<PAGE>

            (e) Furnish to each Holder, without charge, at least one conformed
copy of each such Registration Statement and each amendment thereto, including
financial statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference to the extent requested by such Person, and
all exhibits to the extent requested by such Person (including those previously
furnished or incorporated by reference) promptly after the filing of such
documents with the Commission.

            (f) Promptly deliver to each Holder, without charge, as many copies
of the Prospectus or Prospectuses (including each form of prospectus) and each
amendment or supplement thereto as such Persons may reasonably request in
connection with resales by the Holder of Registrable Securities. Subject to the
terms of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto, except after
the giving on any notice pursuant to Section 3(c).

            (g) If NASDR Rule 2710 requires any broker-dealer to make a filing
prior to executing a sale by a Holder, make an Issuer Filing with the NASDR,
Inc. Corporate Financing Department pursuant to NASDR Rule 2710(b)(10)(A)(i) and
respond within five Trading Days to any comments received from NASDR in
connection therewith, and pay the filing fee required in connection therewith.

            (h) Prior to any resale of Registrable Securities by a Holder, use
its commercially reasonable efforts to register or qualify or cooperate with the
selling Holders in connection with the registration or qualification (or
exemption from the Registration or qualification) of such Registrable Securities
for the resale by the Holder under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder reasonably requests in
writing, to keep each registration or qualification (or exemption therefrom)
effective during the Effectiveness Period and to do any and all other acts or
things reasonably necessary to enable the disposition in such jurisdictions of
the Registrable Securities covered by each Registration Statement; provided,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified, subject the Company to any
material tax in any such jurisdiction where it is not then so subject or file a
general consent to service of process in any such jurisdiction.

            (i) If requested by the Holders, cooperate with the Holders to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to a
Registration Statement, which certificates shall be free, to the extent
permitted by the Purchase Agreement, of all restrictive legends, and to enable
such Registrable Securities to be in such denominations and registered in such
names as any such Holders may request.

            (j) Upon the occurrence of any event contemplated by this Section 3,
as promptly as reasonably possible under the circumstances taking into account
the Company's good faith assessment of any adverse consequences to the Company
and its stockholders of the premature disclosure of such event, prepare a
supplement or amendment, including a post-effective amendment, to a Registration
Statement or a supplement to the related Prospectus or any

                                        6

<PAGE>

document incorporated or deemed to be incorporated therein by reference, and
file any other required document so that, as thereafter delivered, neither a
Registration Statement nor such Prospectus will contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. If the Company notifies the Holders in
accordance with clauses (ii) through (vi) of Section 3(c) above to suspend the
use of any Prospectus until the requisite changes to such Prospectus have been
made, then the Holders shall suspend use of such Prospectus. The Company will
use its best efforts to ensure that the use of the Prospectus may be resumed as
promptly as is practicable. The Company shall be entitled to exercise its right
under this Section 3(j) to suspend the availability of a Registration Statement
and Prospectus, subject to the payment of partial liquidated damages pursuant to
Section 2(b), for a period not to exceed 60 days (which need not be consecutive
days) in any 12 month period.

            (k) Comply with all applicable rules and regulations of the
Commission.

            (l) The Company may require each selling Holder to furnish to the
Company a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and, if required by the Commission, the person
thereof that has voting and dispositive control over the Shares. During any
periods that the Company is unable to meet its obligations hereunder with
respect to the registration of the Registrable Securities solely because any
Holder fails to furnish such information within three Trading Days of the
Company's request, any liquidated damages that are accruing at such time as to
such Holder only shall be tolled and any Event that may otherwise occur solely
because of such delay shall be suspended as to such Holder only, until such
information is delivered to the Company.

      4. Registration Expenses. All fees and expenses incident to the
performance of or compliance with this Agreement by the Company shall be borne
by the Company whether or not any Registrable Securities are sold pursuant to a
Registration Statement. The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with the Trading Market on which the Common Stock is then
listed for trading, (B) in compliance with applicable state securities or Blue
Sky laws reasonably agreed to by the Company in writing (including, without
limitation, fees and disbursements of counsel for the Company in connection with
Blue Sky qualifications or exemptions of the Registrable Securities and
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as requested by the Holders) and (C) if not
previously paid by the Company in connection with an Issuer Filing, with respect
to any filing that may be required to be made by any broker through which a
Holder intends to make sales of Registrable Securities with NASD Regulation,
Inc. pursuant to the NASD Rule 2710, so long as the broker is receiving no more
than a customary brokerage commission in connection with such sale, (ii)
printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities and of printing prospectuses if the
printing of prospectuses is reasonably requested by the holders of a majority of
the Registrable Securities included in a Registration Statement), (iii)
messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Company, (v) Securities Act liability insurance, if the Company
so desires such insurance, and (vi) fees and

                                        7

<PAGE>

expenses of all other Persons retained by the Company in connection with the
consummation of the transactions contemplated by this Agreement. In addition,
the Company shall be responsible for all of its internal expenses incurred in
connection with the consummation of the transactions contemplated by this
Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit and the fees and expenses incurred in connection with the
listing of the Registrable Securities on any securities exchange as required
hereunder. In no event shall the Company be responsible for any broker or
similar commissions or, except to the extent provided for in the Transaction
Documents, any legal fees or other costs of the Holders.

      5. Indemnification

            (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, reasonable attorneys' fees) and expenses (collectively, "Losses"),
as incurred, arising out of or relating to any untrue or alleged untrue
statement of a material fact contained in a Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in light of the circumstances under which
they were made) not misleading, except to the extent, but only to the extent,
that (i) such untrue statements or omissions are based solely upon information
regarding such Holder furnished in writing to the Company by such Holder
expressly for use therein, or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in a Registration Statement, such Prospectus or such form of
Prospectus or in any amendment or supplement thereto (it being understood that
the Holder has approved Annex A hereto for this purpose) or (ii) in the case of
an occurrence of an event of the type specified in Section 3(c)(ii)-(vi), the
use by such Holder of an outdated or defective Prospectus after the Company has
notified such Holder in writing that the Prospectus is outdated or defective and
prior to the receipt by such Holder of the Advice contemplated in Section 6(d).
The Company shall notify the Holders promptly of the institution, threat or
assertion of any Proceeding arising from or in connection with the transactions
contemplated by this Agreement of which the Company is aware.

            (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, to the

                                        8

<PAGE>

extent arising out of or based solely upon: (x) such Holder's failure to comply
with the prospectus delivery requirements of the Securities Act or (y) any
untrue or alleged untrue statement of a material fact contained in any
Registration Statement, any Prospectus, or any form of prospectus, or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission of a material fact required
to be stated therein or necessary to make the statements therein not misleading
(i) to the extent, but only to the extent, that such untrue statement or
omission is contained in any information so furnished in writing by such Holder
to the Company specifically for inclusion in such Registration Statement or such
Prospectus or (ii) to the extent that (1) such untrue statements or omissions
are based solely upon information regarding such Holder furnished in writing to
the Company by such Holder expressly for use therein, or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in a Registration Statement (it
being understood that the Holder has approved Annex A hereto for this purpose),
such Prospectus or such form of Prospectus or in any amendment or supplement
thereto or (2) in the case of an occurrence of an event of the type specified in
Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective
Prospectus after the Company has notified such Holder in writing that the
Prospectus is outdated or defective and prior to the receipt by such Holder of
the Advice contemplated in Section 6(d). In no event shall the liability of any
selling Holder hereunder be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation.

            (c) Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall have the right to assume the defense thereof, including
the employment of counsel reasonably satisfactory to the Indemnified Party and
the payment of all fees and expenses incurred in connection with defense
thereof; provided, that the failure of any Indemnified Party to give such notice
shall not relieve the Indemnifying Party of its obligations or liabilities
pursuant to this Agreement, except (and only) to the extent that it shall be
finally determined by a court of competent jurisdiction (which determination is
not subject to appeal or further review) that such failure shall have prejudiced
the Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall reasonably believe that a material conflict of interest is likely to exist
if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the

                                        9

<PAGE>

Indemnifying Party shall not have the right to assume the defense thereof and
the reasonable fees and expenses of one separate counsel shall be at the expense
of the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

            Subject to the terms of this Agreement, all reasonable fees and
expenses of the Indemnified Party (including reasonable fees and expenses to the
extent incurred in connection with investigating or preparing to defend such
Proceeding in a manner not inconsistent with this Section) shall be paid to the
Indemnified Party, as incurred, within ten Trading Days of written notice
thereof to the Indemnifying Party; provided, that the Indemnified Party shall
promptly reimburse the Indemnifying Party for that portion of such fees and
expenses applicable to such actions for which such Indemnified Party is not
entitled to indemnification hereunder, determined based upon the relative faults
of the parties.

            (d) Contribution. If the indemnification under Section 5(a) or 5(b)
is unavailable to an Indemnified Party or insufficient to hold an Indemnified
Party harmless for any Losses, then each Indemnifying Party shall contribute to
the amount paid or payable by such Indemnified Party, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in this Agreement, any reasonable attorneys' or
other reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission, except in the case of fraud by
such Holder.

                                       10

<PAGE>

            The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

      6. Miscellaneous

            (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

            (b) No Piggyback on Registrations. Except as set forth on Schedule
6(b) attached hereto, neither the Company nor any of its security holders (other
than the Holders in such capacity pursuant hereto) may include securities of the
Company in the Registration Statement other than the Registrable Securities. No
Person has any right to cause the Company to effect the registration under the
Securities Act of any securities of the Company. The Company shall not file any
other registration statements until the Registration Statement required
hereunder is declared effective by the Commission, provided that this Section
6(b) shall not prohibit the Company from filing amendments to registration
statements already filed.

            (c) Compliance. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to a Registration
Statement.

            (d) Discontinued Disposition. Each Holder agrees by its acquisition
of such Registrable Securities that, upon receipt of a notice from the Company
of the occurrence of any event of the kind described in Section 3(d), such
Holder will forthwith discontinue disposition of such Registrable Securities
under a Registration Statement until such Holder's receipt of the copies of the
supplemented Prospectus and/or amended Registration Statement, or until it is
advised in writing (the "Advice") by the Company that the use of the applicable
Prospectus may be resumed, and, in either case, has received copies of any
additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such Prospectus or Registration Statement. The
Company will use its best efforts to ensure that the use of the Prospectus may
be resumed as promptly as it practicable. The Company agrees and acknowledges
that any periods during which the Holder is required to discontinue the
disposition of the Registrable Securities hereunder shall be subject to the
provisions of Section 2(b).

            (e) Piggy-Back Registrations. If at any time during the
Effectiveness Period there is not an effective Registration Statement covering
all of the Registrable Securities and the Company shall determine to prepare and
file with the Commission a registration statement relating to an offering for
its own account or the account of others under the Securities Act of any of its
equity securities, other than on Form S-4 or Form S-8 (each as promulgated under
the

                                       11

<PAGE>

Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with the stock option or other employee
benefit plans, then the Company shall send to each Holder a written notice of
such determination and, if within fifteen days after the date of such notice,
any such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
Holder requests to be registered; provided, however, that, the Company shall not
be required to register any Registrable Securities pursuant to this Section 6(e)
that are eligible for resale pursuant to Rule 144(k) promulgated under the
Securities Act or that are the subject of a then effective Registration
Statement.

            (f) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and each Holder of the then outstanding Registrable Securities. Notwithstanding
the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders and that
does not directly or indirectly affect the rights of other Holders may be given
by Holders of all of the Registrable Securities to which such waiver or consent
relates; provided, however, that the provisions of this sentence may not be
amended, modified, or supplemented except in accordance with the provisions of
the immediately preceding sentence.

            (g) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be delivered as
set forth in the Purchase Agreement.

            (h) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of
the parties and shall inure to the benefit of each Holder. The Company may not
assign its rights or obligations hereunder without the prior written consent of
all of the Holders of the then-outstanding Registrable Securities. Each Holder
may assign their respective rights hereunder in the manner and to the Persons as
permitted under the Purchase Agreement.

            (i) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities, that would have the effect of
impairing the rights granted to the Holders in this Agreement or otherwise
conflicts with the provisions hereof. Except as set forth on Schedule 6(i),
neither the Company nor any of its subsidiaries has previously entered into any
agreement granting any registration rights with respect to any of its securities
to any Person that have not been satisfied in full.

            (j) Execution and Counterparts. This Agreement may be executed in
any number of counterparts, each of which when so executed shall be deemed to be
an original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

                                       12

<PAGE>

            (k) Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be determined
with the provisions of the Purchase Agreement.

            (l) Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

            (m) Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

            (n) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            (o) Independent Nature of Holders' Obligations and Rights. The
obligations of each Holder hereunder are several and not joint with the
obligations of any other Holder hereunder, and no Holder shall be responsible in
any way for the performance of the obligations of any other Holder hereunder.
Nothing contained herein or in any other agreement or document delivered at any
closing, and no action taken by any Holder pursuant hereto or thereto, shall be
deemed to constitute the Holders as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Holders
are in any way acting in concert with respect to such obligations or the
transactions contemplated by this Agreement. Each Holder shall be entitled to
protect and enforce its rights, including without limitation the rights arising
out of this Agreement, and it shall not be necessary for any other Holder to be
joined as an additional party in any proceeding for such purpose.

                              Plan of Distribution

      Each Selling Stockholder (the "Selling Stockholders") of the common stock
("Common Stock") of US Dataworks, Inc., a Nevada corporation (the "Company") and
any of their pledgees, assignees and successors-in-interest may, from time to
time, sell any or all of their shares of Common Stock on the Trading Market or
any other stock exchange, market or trading facility on which the shares are
traded or in private transactions. These sales may be at fixed or negotiated
prices. A Selling Stockholder may use any one or more of the following methods
when selling shares:

            -     ordinary brokerage transactions and transactions in which the
                  broker-dealer solicits purchasers;

            -     block trades in which the broker-dealer will attempt to sell
                  the shares as agent but may position and resell a portion of
                  the block as principal to facilitate the transaction;

            -     purchases by a broker-dealer as principal and resale by the
                  broker-dealer for its account;

            -     an exchange distribution in accordance with the rules of the
                  applicable exchange;

            -     privately negotiated transactions;

            -     settlement of short sales entered into after the effective
                  date of the registration statement of which this prospectus is
                  a part;

            -     broker-dealers may agree with the Selling Stockholders to sell
                  a specified number of such shares at a stipulated price per
                  share;

            -     a combination of any such methods of sale;

            -     through the writing or settlement of options or other hedging
                  transactions, whether through an options exchange or
                  otherwise; or

            -     any other method permitted pursuant to applicable law.

      The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if available, rather
than under this prospectus.

      Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated, but, except as set forth in a supplement to this Prospectus, in the
case of an agency transaction not in excess of a customary brokerage commission
in compliance with NASDR Rule 2440; and in the case of a principal transaction a
markup or markdown in compliance with NASDR IM-2440.

<PAGE>

      In connection with the sale of the Common Stock or interests therein, the
Selling Stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
Common Stock in the course of hedging the positions they assume. The Selling
Stockholders may also sell shares of the Common Stock short and deliver these
securities to close out their short positions, or loan or pledge the Common
Stock to broker-dealers that in turn may sell these securities. The Selling
Stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

      The Selling Stockholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Each Selling Stockholder has
informed the Company that it does not have any written or oral agreement or
understanding, directly or indirectly, with any person to distribute the Common
Stock. In no event shall any broker-dealer receive fees, commissions and markups
which, in the aggregate, would exceed eight percent (8%).

      The Company is required to pay certain fees and expenses incurred by the
Company incident to the registration of the shares. The Company has agreed to
indemnify the Selling Stockholders against certain losses, claims, damages and
liabilities, including liabilities under the Securities Act.

      Because Selling Stockholders may be deemed to be "underwriters" within the
meaning of the Securities Act, they will be subject to the prospectus delivery
requirements of the Securities Act. In addition, any securities covered by this
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under this prospectus. Each Selling
Stockholder has advised us that they have not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the resale shares by the
Selling Stockholders.

      We agreed to keep this prospectus effective until the earlier of (i) the
date on which the shares may be resold by the Selling Stockholders without
registration and without regard to any volume limitations by reason of Rule
144(e) under the Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold pursuant to the prospectus or Rule 144 under the
Securities Act or any other rule of similar effect. The resale shares will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the resale
shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

<PAGE>

      Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the resale shares may not simultaneously engage
in market making activities with respect to the Common Stock for a period of two
business days prior to the commencement of the distribution. In addition, the
Selling Stockholders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including Regulation M, which may
limit the timing of purchases and sales of shares of the Common Stock by the
Selling Stockholders or any other person. We will make copies of this prospectus
available to the Selling Stockholders and have informed them of the need to
deliver a copy of this prospectus to each purchaser at or prior to the time of
the sale.

filed or intends to file with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (the "Registration

of 1933, as amended (the "Securities Act"), of the Registrable Securities, in
accordance with the terms of the Registration Rights Agreement, dated as of June

Statement and the related prospectus.
