                          COMMON STOCK PURCHASE WARRANT

               To Purchase ____________ Shares of Common Stock of

                       US DATAWORKS, INC. (THE "COMPANY")

         This common stock purchase warrant (the "WARRANT") certifies that, for
value received, HOLDER (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 Initial Exercise Date (as defined in Section 4, below) and
on or prior to the close of business on October 2, 2006 (the "TERMINATION DATE")
but not thereafter, to subscribe for and purchase from US Dataworks, Inc., a
corporation incorporated in the State of Nevada (the "COMPANY"), one (1) of
share of common stock, par value $0.0001 per share, of the Company (the "COMMON
STOCK") for every two (2) shares of Common Stock purchased by Purchaser, as
shown as the Subscription Amount set forth in that certain Common Stock and
Warrants Purchase Agreement entered into by and between the Company and the
Holder of even date herewith (the "PURCHASE AGREEMENT"). Capitalized terms used
and not otherwise defined herein shall have the meanings set forth in the
Purchase Agreement.

         1. EXERCISE PRICE. The purchase price of one share of Common Stock (the
"EXERCISE PRICE") under this Warrant shall be Two Dollars ($2.00), subject to
the adjustment for any reverse or forward stock splits, stock dividends, stock
combinations and other similar transactions of the Common Stock that may occur
after the date of this Agreement. In the event that the average closing price
for the Common Stock for the Price Reset Period is less than Two Dollars
($2.00), the Exercise Price shall be adjusted to equal the average closing price
for the Price Reset Period, discounted by twenty-five percent (25%); PROVIDED,
HOWEVER, that under no circumstance will the Exercise Price be less than Sixty
Cents ($0.60). The Exercise Price and the number of shares of Common Stock for
which the Warrant is exercisable (such shares, "WARRANT SHARES") shall be
subject to adjustment as provided herein.

         2. TITLE TO WARRANT. Prior to the Termination Date and subject to
compliance with applicable laws and Section 9 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.

<PAGE>

         3. AUTHORIZATION OF SHARES. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such
issue).

         4. EXERCISE OF WARRANT.

         (a) Exercise of the purchase rights represented by this Warrant may be
made at any time or times on or after the Initial Exercise Date and on or before
the Termination Date by the surrender of this Warrant and the Notice of Exercise
Form annexed hereto duly executed, at the office of the Company (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) and upon payment of the Exercise Price of the shares thereby purchased
by wire transfer or cashier's check drawn on a United States bank, the Holder
shall be entitled to receive a certificate for the number of Warrant Shares so
purchased. The "INITIAL EXERCISE DATE" shall mean October 2, 2003. Certificates
for shares purchased hereunder shall be delivered to the Holder within three (3)
Trading Days after the date on which this Warrant shall have been exercised as
aforesaid. This Warrant shall be deemed to have been exercised and such
certificate or certificates shall be deemed to have been issued, and the 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 6 prior
to the issuance of such shares, have been paid. If the Company fails to deliver
to the Holder a certificate or certificates representing the Warrant Shares
pursuant to this Section 4(a) by the close of business on the third Trading Day
after the date of exercise, then the Holder will have the right to rescind such
exercise. In addition to any other rights available to the Holder, if the
Company fails to deliver to the Holder a certificate or certificates
representing the Warrant Shares pursuant to an exercise by the close of business
on the third Trading Day after the date of exercise, and if after such third
Trading Day the Holder is required by its broker to purchase (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a
sale by the Holder of the Warrant Shares which the Holder anticipated receiving
upon such exercise (a "BUY-IN"), then the Company shall (1) pay in cash to the
Holder the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares
that the Company was required to deliver to the Holder in connection with the
exercise at issue times (B) the price at which the sell order giving rise to
such purchase obligation was executed, and (2) at the option of the Holder,
either reinstate the portion of the Warrant and equivalent number of Warrant
Shares for which such exercise was not honored or deliver to the Holder the

                                      -2-
<PAGE>

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.

         (b) If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the certificate or certificates representing
Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder
to purchase the unpurchased Warrant Shares called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

         5. 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 that 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.

         6. 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.

         7. CLOSING OF BOOKS. The Company will not close its stockholder books
or records in any manner that prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

         8. TRANSFER, DIVISION AND COMBINATION.

         (a) Subject to compliance with any applicable securities laws and the
conditions set forth in Sections 2 and 8(e) 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 Trading
office of the Company, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,

                                      -3-
<PAGE>

the Company shall execute and deliver a 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) 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 8(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 to be divided or combined in accordance
with such notice.

         (c) The Company shall prepare, issue and deliver at its own expense
(other than transfer taxes) the new warrant or warrants under this Section 8.

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

         (e) If, at the time of the surrender of this Warrant in connection with
any transfer of this Warrant, the transfer of this Warrant shall not be
registered pursuant to an effective registration statement under the Securities
Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such transfer (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written
opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
such transfer may be made without registration under the Securities Act and
under applicable state securities or blue sky laws, (ii) that the holder or
transferee execute and deliver to the Company an investment letter in form and
substance reasonably acceptable to the Company.

         9. 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, 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.

         10. 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.

                                      -4-
<PAGE>

         11. 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.

         12. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following. In case the Company shall (i) pay a dividend
in shares of Common Stock or make a distribution in shares of Common Stock to
holders of its outstanding Common Stock, (ii) subdivide its outstanding shares
of Common Stock into a greater number of shares, (iii) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock, or (iv)
issue any shares of its capital stock in a reclassification of the Common Stock,
then the number of Warrant Shares purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted so that the Holder shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which it would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the Holder shall thereafter be entitled to purchase the
number of Warrant Shares or other securities resulting from such adjustment at
an Exercise Price per Warrant Share or other security obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of
the Company resulting from such adjustment. An adjustment made pursuant to this
paragraph shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event. No adjustment of
the Exercise Price shall be made in an amount of less than 1% of the Exercise
Price in effect at the time such adjustment is otherwise required to be made,
but any such lesser adjustment shall be carried forward and shall be made at the
time and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price. In no instance shall any adjustment made pursuant to this
Section 12 cause the Exercise Price to be reduced to a price less than sixty
cents ($0.60) per share.

         13. REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at
the option of the Holder, (a) upon exercise of this Warrant, the number of
shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and Other Property receivable upon
or as a result of such reorganization, reclassification, merger, consolidation

                                      -5-
<PAGE>

or disposition of assets by a Holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event, or (b) cash
equal to the value of this Warrant as determined in accordance with the
Black-Sholes option pricing formula. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant Shares
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 13. For purposes of
this Section 13, "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing provisions of
this Section 13 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

         14. VOLUNTARY ADJUSTMENT BY THE COMPANY. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         15. NOTICE OF ADJUSTMENT. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall give notice thereof to the Holder, which notice shall state the number of
Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares (and other
securities or property) after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth the computation by
which such adjustment was made.

         16. NOTICE OF CORPORATE ACTION. If at any time:

                  (a) the Company shall take a record of the holders of its
         Common Stock for the purpose of entitling them to receive a dividend or
         other distribution, or any right to subscribe for or purchase any
         evidences of its indebtedness, any shares of stock of any class or any
         other securities or property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
         any reclassification or recapitalization of the capital stock of the
         Company or any consolidation or merger of the Company with, or any
         sale, transfer or other disposition of all or substantially all the
         property, assets or business of the Company to, another corporation or,

                                      -6-
<PAGE>

                  (c) there shall be a voluntary or involuntary dissolution,
         liquidation or winding up of the Company;

         then, in any one or more of such cases, the Company shall give to
Holder (i) at least 20 days' prior written notice of the date on which a record
date shall be selected for such dividend, distribution or right or for
determining rights to vote in respect of any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
liquidation or winding up, and (ii) in the case of any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up, at least 20 days' prior written notice
of the date when the same shall take place. Such notice in accordance with the
foregoing clause also shall specify (i) the date on which any such record is to
be taken for the purpose of such dividend, distribution or right, the date on
which the holders of Common Stock shall be entitled to any such dividend,
distribution or right, and the amount and character thereof, and (ii) the date
on which any such reorganization, reclassification, merger, consolidation, sale,
transfer, disposition, dissolution, liquidation or winding up is to take place
and the time, if any such time is to be fixed, as of which the holders of Common
Stock shall be entitled to exchange their Warrant Shares for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 18(d).

         17. AUTHORIZED SHARES. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Trading Market upon
which the Common Stock may be listed. Except and to the extent as waived or
consented to by the Holder, the Company shall not by any action, including,
without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder as set forth in this Warrant against impairment. Without
limiting the generality of the foregoing, the Company will (a) not increase the
par value of any Warrant Shares above the amount payable therefor upon such
exercise immediately prior to such increase in par value, (b) take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares upon the exercise
of this Warrant, and (c) use commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant. Before taking any action which would result in
an adjustment in the number of Warrant Shares for which this Warrant is

                                      -7-
<PAGE>

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.

         18. Miscellaneous.

                  (a) JURISDICTION. This Warrant shall constitute a contract
         under the laws of Nevada, without regard to its conflict of law,
         principles or rules.

                  (b) RESTRICTIONS. The Holder acknowledges that the Warrant
         Shares acquired upon the exercise of this Warrant, if not registered,
         will have restrictions upon resale imposed by state and federal
         securities laws.

                  (c) NONWAIVER AND EXPENSES. No course of dealing or any delay
         or failure to exercise any right hereunder on the part of Holder shall
         operate as a waiver of such right or otherwise prejudice Holder's
         rights, powers or remedies, notwithstanding all rights hereunder
         terminate on the Termination Date. If the Company willfully and
         knowingly fails to comply with any provision of this Warrant, which
         results in any material damages to the Holder, the Company shall pay to
         Holder such amounts as shall be sufficient to cover any costs and
         expenses including, but not limited to, reasonable attorneys' fees,
         including those of appellate proceedings, incurred by Holder in
         collecting any amounts due pursuant hereto or in otherwise enforcing
         any of its rights, powers or remedies hereunder.

                  (d) NOTICES. Any notice, request or other document required or
         permitted to be given or delivered to the Holder by the Company shall
         be delivered in accordance with the notice provisions of the Purchase
         Agreement; provided upon any permitted assignment of this Warrant, the
         assignee shall promptly provide the Company with its contact
         information.

                  (e) LIMITATION OF LIABILITY. No provision hereof, in the
         absence of any affirmative action by Holder to exercise this Warrant or
         purchase Warrant Shares, and no enumeration herein of the rights or
         privileges of Holder, shall give rise to any liability of Holder for
         the purchase price of any Common Stock or as a stockholder of the
         Company, whether such liability is asserted by the Company or by
         creditors of the Company.

                  (f) REMEDIES. Holder, in addition to being entitled to
         exercise all rights granted by law, including recovery of damages, will
         be entitled to specific performance of its rights under this Warrant.
         The Company agrees that monetary damages would not be adequate
         compensation for any loss incurred by reason of a breach by it of the
         provisions of this Warrant and hereby agrees to waive the defense in
         any action for specific performance that a remedy at law would be
         adequate.

                  (g) SUCCESSORS AND ASSIGNS. Subject to applicable securities
         laws, this Warrant and the rights and obligations evidenced hereby
         shall inure to the benefit of and be binding upon the successors of the
         Company and the successors and permitted assigns of Holder. The

                                      -8-
<PAGE>

         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.

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

                  (i) SEVERABILITY. Wherever possible, each provision of this
         Warrant shall be interpreted in such manner as to be effective and
         valid under applicable law, but if any provision of this Warrant shall
         be prohibited by or invalid under applicable law, such provision shall
         be ineffective to the extent of such prohibition or invalidity, without
         invalidating the remainder of such provisions or the remaining
         provisions of this Warrant.

                  (j) HEADINGS. The headings used in this Warrant are for the
         convenience of reference only and shall not, for any purpose, be deemed
         a part of this Warrant.

IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by its
officer thereunto duly authorized.

                             REGISTRATION AGREEMENT

         THIS REGISTRATION AGREEMENT (this "AGREEMENT"), dated as of October 2,
2003, between US DATAWORKS, INC. a Nevada corporation (the "COMPANY"), and THE
SIGNATORIES HERETO (each a "HOLDER"). Holder is one of several other holders
(collectively, the "HOLDERS") participating in that certain Common Stock
Purchase and Warrants Agreement of even date and/or that certain Convertible
Debenture and Warrants Agreement of even date herewith (collectively, the
"PURCHASE AGREEMENT") and the rights described herein shall apply to the Holders
collectively as a single entity.

                                   WITNESSETH

         Holder is acquiring from the Company shares of Common Stock and
warrants (the "WARRANTS") relating to the Purchase Agreement. The Shares (as
defined below) will be "restricted securities" as defined in Rule 144 under the
Securities Act of 1933, as amended. As a result, there will be substantial
restrictions on the ability of the Holders to sell the Shares in the absence of
registration under the Securities Act of 1933 and applicable state securities
laws. In order to enable the Holders to sell all or a portion of the Shares, the
Company has agreed to the terms of this Agreement.

         NOW THEREFORE, in consideration of the premises, and other good and
valuable consideration, the receipt, adequacy and sufficiency of which are
hereby acknowledged by the parties, the parties hereby agree as follows:

1.       REGISTRATION

of its securities, in each case not in the ordinary course of business, such
that registration or qualification of the Registrable Securities would have a
material adverse effect on the Company and its shareholders, and (ii) ending as

registration statement on Form S-3 that covers the resale of some or all of the
Holders' Registrable Securities in an offering to be made on a continuous basis
pursuant to Rule 415, the Company shall provide each Holder written notice
thereof at least 20 days before filing such registration statement with the SEC.
The Company shall thereupon include in such filing (and any related filing or
qualification under blue sky laws or other state securities laws) all of the
Registrable Securities for which registration is made available.

                  (b) Notwithstanding the foregoing, if the Company shall
furnish to Holders participating in the registration pursuant to this Section
1.2 a certificate signed by the President of the Company stating that a Blackout
Period is in effect, the Company shall have the right to cause all sales to be
delayed during the term of such Blackout Period; PROVIDED, HOWEVER, that the
Company may utilize such deferral (including any such deferral that may be
declared pursuant to Section 1.3(b)) not more than once in any 12-month period.

                  (c) The Company may propose to include additional shares of
Common Stock or other securities to be sold by the Company and/or by other
holders of Common Stock or other securities (the "ADDITIONAL SECURITIES") in any
registration statement to be filed pursuant to this Section 1.2.

                  (d) The Holders shall have the right to select the underwriter
or underwriters, if any, subject to the approval of the Company, which approval
shall not be unreasonably withheld or delayed, that will undertake the sale and
distribution from time to time of the Registrable Securities included in a
registration statement filed under the provisions of this Section 1.2.

         1.3 DEMAND REGISTRATIONS.

                  (a) Unless the shelf registration contemplated by Section 1.2
or the piggy-back registration contemplated by Section 1.4 has been filed and
declared effective by the SEC, covers all then outstanding Registrable
Securities and is then currently in effect, then the Company shall, at the
request of the Holders of at least 250,000 shares of Registrable Securities,

                                      -3-
                                                              US Dataworks, Inc.
                                                          Registration Agreement
                                                                 October 2, 2003
<PAGE>

prepare and use its commercially reasonable efforts to file with the SEC as
promptly as practicable, but in any event within 45 days of such request, a
registration statement on Form S-3 covering the resale of the Registered
Securities requested to be covered by such demand. The Company shall use its
commercially reasonable efforts to cause such registration statement to be filed
not later than 45 days following the receipt of the notice of demand for
registration under this Section 1.3, and shall use its commercially reasonable
efforts to cause such registration statement to be declared effective under the
Act (including filing with the SEC a request for acceleration of effectiveness
in accordance with Rule 12dl-2 promulgated under the 1934 Act) as promptly as
practicable after the filing thereof, but in any event prior to the
Effectiveness Due Date, and to keep such registration statement continuously
effective under the Act until the date on which all Registrable Securities
covered by such registration statement have been sold or cease to be Registrable
Securities, or such earlier time that the Holders may sell all their Registrable
Securities within a single 90-day period under Rule 144 (such period, the
"EFFECTIVENESS PERIOD"); provided that the Company shall provide the Holders
with written notice of its intent to terminate the effectiveness of such
registration statement not fewer than three (3) business days prior to such
termination. Notwithstanding the foregoing, if at the time the Holders deliver
to the Company a notice requesting registration of Registrable Securities
pursuant to this Section 1.3(a) the Holders are able to sell pursuant to Rule
144, within the 90-day period commencing on the date that the demand notice is
received by the Company, all of the Registrable Securities that are then not
covered by an effective registration statement, then the Company shall not be
required to file a registration statement pursuant to this Section 1.3 in
response to such demand, and such request shall not be deemed a demand
registration for purposes of Section 1.3(f) of this Agreement.

                  (b) Notwithstanding the foregoing, if the Company shall
furnish to Holders participating in the registration pursuant to this Section
1.3 a certificate signed by the President of the Company stating that a Blackout
Period is in effect, the Company shall have the right to defer such filing or
sales under the registration statement filed pursuant to this Section 1.3 during
the term of such Blackout Period; PROVIDED, HOWEVER, that the Company may
utilize such deferral (including any such deferral that may be declared pursuant
to Section 1.2(b)) not more than once in any 12-month period.

                  (c) If, at any time during the Effectiveness Period, the
Company is not eligible to register its securities on Form S-3, the Company
shall prepare and file a registration statement on Form S-1 or S-2 (or other
available form for the general registration of securities) as may be necessary
to register all Registrable Securities in accordance with the terms and
conditions set forth in this Section 1.3.

                  (d) The Company may propose to include Additional Securities
in any registration statement to be filed pursuant to this Section 1.3. The
Holders shall have the right to reduce the number of Additional Securities
requested to be registered by the Company pursuant to this Section 1.3(d)
(including, if necessary, to zero) if, in the good faith opinion of the
underwriter or underwriters of such offering, the inclusion of such Additional
Securities would materially and adversely affect the marketability or price of
the Registrable Securities to be offered by the Holders in such registration.

                                                              US Dataworks, Inc.
                                                          Registration Agreement
                                                                 October 2, 2003
<PAGE>

                  (e) The Holders shall have the right to select the underwriter
or underwriters, if any, subject to the approval of the Company, which approval
shall not be unreasonably withheld or delayed, that will undertake the sale and
distribution from time to time of the Registrable Securities included in a
registration statement filed under the provisions of this Section 1.3.

                  (f) The Company shall be obligated to effect only one (1) such
demand registrations pursuant to this Section 1.3.

                  (g) The Holders of Registrable Securities may withdraw their
demand for any proposed offering pursuant to a demand registration by giving
written notice from a majority of such Holders to the Company of their election
to withdraw prior to the effectiveness of the registration statement with the
SEC. If such withdrawing Holders pay all registration expenses incurred in
connection with such demand registration, then no demand registration shall be
deemed to have been made for purposes of Section 1.3(f). If such withdrawing
Holders do not pay all registration expenses set forth in Section 1.7 of this
Agreement incurred by the Company in connection with such demand registration,
then such withdrawn registration shall be deemed a demand registration for
purposes of Section 1.3(f) above.

         1.4 PIGGYBACK REGISTRATION RIGHTS.

                  (a) If at any time the Company proposes to file on its behalf
and/or on behalf of any of its securityholders a registration statement under
the Act on Form S-1, S-2 or S-3 (or any other appropriate form that may be used
for the registration of Registrable Securities) with respect to any of its
capital stock or other securities, the Company shall give each Holder written
notice (which notice shall include a list of jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable blue sky or
other state securities laws, the proposed offering price and the plan of
distribution) at least 20 days before the filing with the SEC of such
registration statement. If any Holder desires to have Registrable Securities
registered pursuant to this Section 1.4, such Holder shall so advise the Company
in writing within 10 days after the date of receipt of such notice from the
Company (the "PARTICIPATION NOTICE"). The Company shall thereupon include in
such filing (and any related filing or qualification under blue sky laws or
other state securities laws) the number of Registrable Securities for which
registration is so requested, subject to its right to reduce the number of
Registrable Securities as hereinafter provided, and shall use its commercially
reasonable efforts to effect registration under the Act of such Registrable
Securities on the same terms and conditions as any similar securities of the
Company included therein.

                  (b) the Holders participating in such piggyback registration
shall pay any additional registration fee, payable to the SEC in accordance with
Rule 457(c) under the Act, incurred as a result of the inclusion of Registrable
Securities on such registration statement. Notwithstanding the foregoing, the
Company shall not be required to provide notice of filing of a registration
statement and to include therein any Registrable Securities if the proposed
registration is:

<PAGE>

                           (i) a registration of stock options, stock purchases
or compensation or incentive plans, or of securities issued or issuable pursuant
to any such plan, or a dividend reinvestment plan on Form S-8, or other
comparable form then in effect; or

                           (ii) a registration of securities proposed to be
issued in exchange for securities or assets of, or in connection with, a merger
or consolidation with another corporation.

                  (c) In the event the offering in which any Holder's
Registrable Securities to be included pursuant to this Section 1.4 is to be
underwritten, the Company shall furnish the Holders with a written opinion of
the managing or principal underwriter as to the Maximum Includable Securities as
promptly as practicable, but in any event within 10 business days after the
Company's receipt of Holder's Participation Notice. If the total number of
securities proposed to be included in such registration statement exceeds the
Maximum Includable Securities, the number of securities to be included within
the coverage of such registration statement shall be reduced to the Maximum
Includable Securities as follows:

                           (i) no reduction shall be made in the number of
shares of capital stock or other securities to be registered for the account of
the Company in a primary offering of securities; and

                           (ii) the number of Registrable Securities and other
securities that may be included in the registration, if any, shall be allocated
among the Holders of Registrable Securities and holders of other securities (the
"OTHER HOLDERS") requesting inclusion on a pro rata basis, with the number of
each type or class of securities of each Holder and Other Holder thereof
included in the registration to be that number determined by multiplying (A) the
total number of such type or class of security included in the Maximum
Includable Securities less (B) the number of such type or class of security to
be registered for the account of the Company, by a fraction, the numerator of
which will be the total number of such type or class of security that such
Holder or Other Holder owns, and the denominator of which will be the total
number of such type or class of security owned by all Holders and Other Holders
that have requested inclusion of such type or class of security in the
registration.

                  (d) The Company shall, in its sole reasonable discretion,
select the underwriter or underwriters, if any, that are to undertake the sale
and distribution of the Registrable Securities to be included in a registration
statement filed under the provisions of this Section 1.4.

                  (e) The right to registration provided in this Section 1.4 is
in addition to and not in lieu of the shelf registration that the Company may
effect pursuant to Section 1.2 or any demand registration that the Company is
required to effect pursuant to Section 1.3; PROVIDED, HOWEVER, that in the event
a Holder elects to participate in a registration pursuant to this Section 1.4 to
register Registrable Securities already covered by an effective registration
statement filed pursuant to Section 1.2 or 1.3 of this Agreement, then such
Holders shall be entitled to participate in such registration pursuant to this
Section 1.4 only if (i) such Holder pays the registration filing fee applicable
to such Registrable Securities to be included in the registration statement
filed pursuant to this Section 1.4, and such other registration fees and

expenses (including reasonable attorney's fees) otherwise payable by the Company
pursuant to Section 1.7 to the extent such fees were incurred and paid by the
Company in connection with the effective registration statement covering such
Registrable Securities, (ii) such registration statement to be filed pursuant to
this Section 1.4 is in connection with an underwritten offering and (iii) the
Registrable Securities to be covered in such registration are not already
covered by a registration statement in connection with an underwritten offering.

                  (f) Any or all of the Holders of Registrable Securities may
withdraw such Holder's request for inclusion of Registrable Securities in any
piggy-back registration under this Section 1.4 by giving written notice to the
Company of their election to withdraw prior to the effectiveness of the
registration statement with the SEC. The Company may also elect to withdraw a
registration statement filed pursuant to this Section 1.4 at any time prior to
the effectiveness of such registration statement; PROVIDED, HOWEVER, that the
Company shall pay all registration expenses incurred in connection with such
piggy-back registration as provided in Section 1.7 (including refunding any SEC
registration fees paid by participating Holders pursuant to Section 1.4(a)).

         1.5 OBLIGATIONS OF THE COMPANY. Whenever effecting the registration of
any Registrable Securities under Section 1.2, Section 1.3 or Section 1.4, the
Company shall, as promptly as practicable:

                  (a) Before filing a registration statement or prospectus or
any amendments or supplements thereto, furnish to the Holders of the Registrable
Securities covered by such registration statement, the underwriters, if any, and
their respective counsel, copies of all such documents proposed to be filed,
which documents shall be made available for prior review by such Holders,
underwriters and their respective counsel, and make such changes in such
documents relating to such Holders or underwriters prior to the filing thereof
as such Holders, underwriters and their respective counsel may reasonably
request; PROVIDED, HOWEVER, that: (i) the Company shall not file any such
registration statement or any amendment, prospectus or supplement thereto to
which the Holders of a majority in number of the Registrable Securities covered
by such registration statement shall reasonably object with respect to
information furnished expressly for use in connection with such registration by
such Holders, which objection shall be provided by such Holders to the Company
within three business days after such Holders receive any such document, and
(ii) with respect to any underwritten offering in which such Holders are subject
to indemnification obligations under any applicable underwriting agreement, the
Company shall not file any such registration statement or any amendment,
prospectus or supplement thereto to which the Holders of a majority in number of
the Registrable Securities covered by such registration statement or the
underwriters shall reasonably object, which objection if any shall be provided
by such Holders or such underwriters to the Company within three business days
after such Holders or underwriters, as the case may be, receive any such
document.

                  (b) Prepare and file with the SEC a registration statement on
such form as necessary to register and qualify the Registrable Securities and

reference contains an untrue statement of material fact or omits to state a
material fact required to be stated therein or necessary to make the statements

notify such Holders of the filing of, any amendment or supplement to such
registration statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to such
securities is required to be delivered under the Act, any event has occurred as
the result of which any such prospectus must be amended in order that it does

fact necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading.

                  (n) In case any Holder or any underwriter for any such Holder
is required to deliver a prospectus at a time when the prospectus then in effect
may no longer be used under the Act, prepare promptly upon request such
amendment or amendments to such registration statement and such prospectus as
may be necessary to permit compliance with the requirements of the Act.

                  (o) If any similar securities of the Company are then listed
on the American Stock Exchange or any other securities exchange, or are
qualified and eligible for trading in any automated quotation system, the
Company will cause all such Registrable Securities covered by such registration
statement to be listed the American Stock Exchange or such other securities
exchange, and to be qualified and eligible for trading in such automated

Registrable Securities being sold in connection with an underwritten offering,
immediately incorporate in a prospectus supplement or post-effective amendment
such necessary information as the underwriters or the Holders of a majority in
number of the Registrable Securities being sold reasonably request to have
included therein relating to the plan of distribution with respect to such
Registrable Securities, including, without limitation, information with respect
to the amount of Registrable Securities being sold to underwriters, the purchase
price being paid therefor by any underwriters and with respect to any other
terms of the underwritten (or best efforts underwritten) offering of the
Registrable Securities to be sold in such offering; and make all required

sale of Registrable Securities to the underwriters.

                  (r) Otherwise comply with all applicable rules and regulations
of the SEC, and, once initiated by the Company, thereafter make generally

of Section 11(a) of the Act and Rule 158 of the SEC promulgated thereunder (or
any successor rule or regulation hereafter adopted by the SEC), no later than 30
days after the end of any 12-month period (or 45 or 90 days if the end of such
12-month period coincides with the end of a fiscal quarter or fiscal year,
respectively, of the Company, or such shorter period as the SEC shall require
from time to time with respect to the filing by a reporting company of such
documents on Forms 10-Q or 10-K, respectively): (i) commencing at the end of any
month in which Registrable Securities are sold to underwriters in an
underwritten offering or (ii) if not sold to underwriters in such an offering,
beginning with the first month commencing after the effective date of the
registration statement, which statements shall cover said 12-month periods.

                  (s) Cooperate and assist in any filings required to be made

underwriter (including any "qualified independent underwriter" that is required
to be retained in accordance with the rules and regulations of the NASD).

                  (t) Promptly prior to the filing of any document which is to
be incorporated by reference into the registration statement or the prospectus
(after initial filing of the registration statement), provide copies of such
document to counsel to the selling Holders of Registrable Securities and to the
underwriters, if any, make the Company's representatives available for
discussion of such document and make such changes in such document with respect
to the Holders or the underwriters, if any, prior to the filing thereof as
counsel for such selling Holders or underwriters may reasonably request.

                  (u) In the event of any underwritten public offering, if
requested to do so by the underwriters managing such offering, enter into a
customary holdback agreement related to such offering.

                  (v) Provide a transfer agent and registrar for all Registrable
Securities sold under the registration statement not later than the effective
date of the registration statement.

         1.6 OBLIGATIONS OF HOLDERS. Each of the selling Holders shall:

                  (a) Furnish to the Company such information regarding
themselves, the Registrable Securities held by them, the intended method of sale
or other disposition of such securities if the registration is pursuant to
Section 1.3, the identity of and compensation to be paid to any underwriters
proposed to be employed in connection with such sale or other disposition if the
registration is pursuant to Section 1.3, and such other information as may
reasonably be required to effect the registration of their Registrable
Securities.

                  (b) Notify the Company, at any time when a prospectus relating
to Registrable Securities covered by a registration statement is required to be
delivered under the Act, of the existence of any fact or the happening of any
event with respect to such selling Holder as a result of which information
provided by such Holder expressly for use in the prospectus included in such
registration statement, as then in effect, causes such prospectus to include an
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances in which they were made, not misleading.

                  (c) In the event of any underwritten public offering, each
Holder participating in such underwriting shall enter into and perform its
obligations under the underwriting agreement for such offering, and if requested
to do so by the underwriters managing such offering, each Holder shall enter
into a customary holdback agreement.

         1.7 EXPENSES OF REGISTRATION. The Company shall bear and pay all
expenses incurred in connection with registrations, filings or qualifications
pursuant to Section 1.2, Section 1.3 and Section 1.4, including (without
limitation) the fees and disbursements of underwriters (other than underwriting
discounts and commissions with respect to Registrable Securities included in
such registration), PROVIDED, HOWEVER, that if the applicable registration does
not cover shares issued on behalf of the Company, then such payment shall not
exceed $10,000, and PROVIDED, FURTHER, that in the case of a registration
pursuant to Section 1.4 of this Agreement that does not include any shares sold
on behalf of the Company, then the Holders shall only be required to bear such
expenses allocable to the Registrable Securities in excess of $10,000 to the
extent all other selling stockholders bear such expenses on a pro rata basis,
based on the number of shares registered; registration, filing and qualification
fees; blue sky fees and expenses (including, without limitation, fees and
disbursements of counsel or the underwriters in connection with blue sky
qualifications of the Registrable Securities and determination of their
eligibility for investment under the laws of such jurisdictions as the Holders
or underwriters of the Registrable Securities being sold may designate);
printers' and accounting fees (including, without limitation, the expenses of
any special audit and "cold comfort" letters required by or incident to services
provided by such accountants); messenger, telephone and delivery expenses; costs
of listing on the American Stock Exchange or other securities exchange on which
similar securities issued by the Company are then listed; costs of furnishing
such copies of each preliminary prospectus, final prospectus and amendments
thereto as each Holder may reasonably request; fees and disbursements of counsel
for the Company; fees and disbursements of one counsel for the selling Holders
of Registrable Securities, not to exceed $10,000 per registration; fees and
expenses associated with any NASD filing required to be made in connection with
the registration statement, including in the event the Company selects or
approves the underwriters in connection with any such offering, if applicable,
the fees and expenses of any "qualified independent underwriter" (and its
counsel) that is required to be retained in accordance with the rules and
regulations of the NASD; and fees and expenses of other persons retained by the
Company in connection with the registrations, filings or qualifications pursuant
to Section 1.2, Section 1.3 and Section 1.4. Without limiting the generality of
the foregoing, the Company shall pay its internal expenses (including, without
limitation, all salaries and expenses of its officers and employees performing
legal or accounting duties), the expense of any annual audit, the fees and
expenses incurred in connection with the listing of the securities to be
registered on each securities exchange on which similar securities issued by the
Company are then listed, rating agency fees and the fees and expenses of any
person, including special experts, retained by the Company in connection with
the registrations, filings or qualifications pursuant to Section 1.2, Section
1.3 and Section 1.4.

         1.8 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Agreement:

                  (a) The Company will indemnify and hold harmless, to the full
extent permitted by law, each Holder, the officers, directors, employees,
affiliates and agents of each Holder, any underwriter (as defined in the Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Act or the 1934 Act (each, an "INDEMNIFIED HOLDER"),

                                      -12-
                                                              US Dataworks, Inc.
                                                          Registration Agreement
                                                                 October 2, 2003

against any losses, claims, damages and liabilities (joint or several), and
expenses (including costs of investigation and legal expenses) incurred in
connection with investigating, preparing or defending against such losses,
claims, damages and liabilities (collectively, "LOSSES") to which such
Indemnified Holder may become subject under the Act, the 1934 Act, or other
federal, state, local, foreign or other law, insofar as such Losses arise out of
or are based upon any of the following statements, omissions or violations
(collectively a "VIOLATION"): (i) any untrue statement or alleged untrue
statement of a material fact contained in any registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; PROVIDED, HOWEVER, that the indemnity
agreement contained in this Section 1.8(a) shall not apply to amounts paid in
settlement of any such Loss if such settlement is effected without the consent
of the Company, which consent shall not be unreasonably withheld or delayed, nor
shall the Company be liable in any such Loss to the extent that it arises out of
or is based upon (i) a Violation that occurs in reliance upon and in conformity
with written information furnished expressly for use in connection with such
registration by such Indemnified Holder, or (ii) the failure of such Indemnified
Holder to deliver a copy of the registration statement or the prospectus, or any
amendments or supplements thereto, after the Company has furnished such person
with a sufficient number of copies of the same.

                  (b) Each selling Holder will indemnify and hold harmless, to
the full extent permitted by law, the Company and each of its officers,
directors, employees, affiliates and agents, and each person, if any, who
controls the Company within the meaning of the Act or the 1934 Act (each, a
"COMPANY INDEMNITEE"), against any Losses to which any such Company Indemnitee
may become subject under the Act, the 1934 Act, or other federal, state, local,
foreign or other law, insofar as such Losses arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration;
PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 1.8(b)
shall not apply to amounts paid in settlement of any such Losses if such
settlement is effected without the consent of such Holder, which consent shall
not be unreasonably withheld or delayed. Notwithstanding anything to the
contrary herein contained, a Holder's indemnity obligation, in such person's
capacity as a Holder, shall be limited to the net proceeds received by such
Holder from the offering out of which the indemnity obligation arises.

                  (c) Promptly after receipt by an indemnified party under this
Section 1.8 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.8, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnified party, except that such fees and expenses shall be paid by
the indemnifying party if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual

                                      -13-
                                                              US Dataworks, Inc.
                                                          Registration Agreement

or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceedings. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 1.8, but the omission so to deliver
written notice to the indemnifying party will not otherwise relieve it of any
liability that it may have to any indemnified party under this Section 1.8.

                  (d) If the indemnification provided for in this Section 1.8 is
unavailable to an indemnified party under Section 1.8(a) or Section 1.8(b)
hereof (other than by reason of exceptions provided in those Sections) in
respect of any Losses referred to therein, then each applicable indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such Losses: (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company Indemnities, on the one hand, and of the Indemnified Holders, on
the other hand, in connection with the statements or omissions that resulted in
such Losses, or (ii) if the allocation provide in clause (i) is not then
permitted under applicable law, in such proportion as is appropriate to reflect
the relative fault of the Company Indemnities, on the one hand, and of the
Indemnified Holders, on the other hand, in connection with the statements or
omissions which resulted in such Losses, as well as any other relevant equitable
considerations. The relative fault of the Company Indemnities, on the one hand,
and of the Indemnified Holders, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company Indemnities or by the Indemnified
Holders and such parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

                  The Company and each Holder agree that it would not be just
and equitable if contribution pursuant to this Section 1.8(d) were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 1.8(d), no underwriter
shall be required to contribute any amount of excess of the amount of which the
total net proceeds received by such underwriter from the sale of the Registrable
Securities underwritten by it exceeds the amount of any damages that such
underwriter has otherwise been required to pay by reason of such Violation, and
a Holder shall not be required to contribute any amount in excess of the amount
by which the total net proceeds received by such Holder from the sale of the
Registrable Securities exceeds the amount of any damages which such Holder, or
its affiliated Holders, has otherwise been required to pay by reason of such
Violation. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. Each Holder's
obligations to contribute pursuant to this Section 1.8 are several in the
proportion that the net proceeds of the offering received by such Holder bears
to the total net proceeds of the offering received by all the Holders, and not
joint.

                  (e) The indemnification provided by this Section 1.8 shall be
a continuing right to indemnification and shall survive the registration and
sale of any of the Registrable Securities hereunder and the expiration or
termination of this Agreement.

         1.9 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to
making available to the Holders the benefits of Rule 144, the Company agrees to
use commercially reasonable efforts to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

                  (c) furnish to any Holder, as long as the Holder owns any

of damages for breach of any part of this Agreement.

         2.10 INDULGENCES, NOT WAIVERS. Neither the failure nor any delay on the
part of a party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or any other right, remedy, power or privilege, nor shall
any waiver of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege
with respect to any other occurrence. No waiver shall be effective unless it is
in writing and is signed by the party asserted to have granted such waiver.

         2.11 EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be deemed to be an original as

together constitute one and the same instrument. This Agreement shall become
binding when one or more counterparts hereof, individually or taken together,
shall bear the signatures of all of the parties reflected hereon as the
signatories. Any photographic or xerographic copy of this Agreement, with all
signatures reproduced on one or more sets of signature pages, shall be
considered for all purposes as of it were an executed counterpart of this
Agreement.

         2.12 SEVERABILITY 2.13 Each and every provision set forth in this
Agreement is independent and severable from the others, and no provision shall
be rendered unenforceable by virtue of the fact that, for any reason, any other
or others of them may be unenforceable in whole or in part. The parties hereto
agree that if any provision of this Agreement shall be declared by a court of
competent jurisdiction to be unenforceable for any reason whatsoever, the court
may appropriately limit or modify such provision, and such provision shall be
given effect to the maximum extent permitted by applicable law.

IN WITNESS WHEREOF, the undersigned has executed this Agreement as of the date
and year first above written.
