                             STOCK PURCHASE WARRANT

                   To Purchase ____ Shares of Common Stock of

                             Eco Soil Systems, Inc.

         THIS CERTIFIES that, for value received, [INVESTOR] (the "Holder"),
is entitled, upon the terms and subject to 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 January 24, 2005 (the
"Termination Date") but not thereafter, to subscribe for and purchase from
Eco Soil Systems, Inc., a corporation incorporated in Nebraska (the
"Company"), up to [NUMBER] (#) shares (the "Warrant Shares") of Common Stock,
$0.005 par value, of the Company (the "Common Stock"). The initial purchase
price of one share of Common Stock (the "Exercise Price") under this Warrant
shall be $4.488, as set forth in the Convertible Debentures and Warrants
Purchase Agreement dated as of January 17, 2000 pursuant to which this
Warrant has been issued (the "Purchase Agreement"). The Exercise Price and
the number of shares for which the Warrant is exercisable shall be subject to
adjustment as provided herein. In the event of any conflict between the terms
of this Warrant and the Purchase Agreement, the Purchase Agreement shall
control. Capitalized terms used and not otherwise defined herein shall have
the meanings set forth for such terms in the Purchase Agreement.

<PAGE>

         1.  TITLE TO WARRANT.  Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by
the holder hereof in person or by duly authorized attorney, upon surrender of
this Warrant together with the Assignment Form annexed hereto properly
endorsed.

         2.  AUTHORIZATION OF SHARES.  The Company covenants that all shares
of Common Stock which may be issued upon the exercise of rights represented
by this Warrant will, upon exercise of the 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).

         3.  EXERCISE OF WARRANT.  Except as provided in Section 4 herein,
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 before the close
of business on 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 hereof 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 of this Warrant shall be
entitled to receive a certificate for the number of shares of Common Stock so
purchased. This Warrant may also be exercised in whole or in part by means of
a "cashless exercise" by means of tendering this Warrant to the Company to
receive a number of shares of Common Stock equal in Market Value to the
difference between the Market Value of the shares of Common Stock issuable
upon such exercise of this Warrant and the total cash exercise price of that
part of the Warrant being exercised. Market Value for this purpose shall be
the last trade on the Trading Day of such cashless exercise. Certificates for
shares purchased hereunder shall be delivered to the holder hereof 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
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 Holder, if any, pursuant to
Section 5 prior to the issuance of such shares, have been paid. 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 shares of Common Stock called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

         4.  NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be
entitled to purchase upon such exercise, the Company shall pay a cash
adjustment in respect of such final fraction in an amount equal to the
Exercise Price.

                                       2
<PAGE>

         5.  CHARGES, TAXES AND EXPENSES.  Issuance of certificates for
shares of Common Stock upon the exercise of this Warrant shall be made
without charge to the holder hereof for any issue 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 of this Warrant or in such name or names as
may be directed by the holder of this Warrant; provided, however, that in the
event certificates for shares of Common Stock are to be issued in a name
other than the name of the holder of this Warrant, this Warrant when
surrendered for exercise shall be accompanied by the Assignment Form attached
hereto duly executed by the holder hereof and the Company may require, as a
condition thereto, the payment of a sum sufficient to reimburse it for any
transfer tax incidental thereto.

         6.  CLOSING OF BOOKS.  The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant.

         7.  TRANSFER, DIVISION AND COMBINATION.  (a)  Subject to compliance
with any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the
Company to be maintained for such purpose, 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
Holder or its agent or attorney and funds sufficient to pay any transfer
taxes payable upon the making of such transfer. Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant
or Warrants in the name of the assignee or assignees and in the denomination
or denominations specified in such instrument of assignment, and shall issue
to the assignor a new Warrant evidencing the portion of this Warrant not so
assigned, and this Warrant shall promptly be cancelled. A Warrant, if
properly assigned, may be exercised by a new holder for the purchase of
shares of Common Stock 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 Holder or its agent or
attorney. Subject to compliance with Section 7(a), as to any transfer which
may be involved in such division or combination, the Company shall execute
and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice.

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

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

         8.  NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE.  This Warrant does not
entitle the holder hereof 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.

                                       3
<PAGE>

         9.  LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT.  The Company
covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant certificate 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 shall not include the posting of any
bond except as required by the Company's transfer agent), 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.

         10.  SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed
day for the taking of any action or the expiration of any right required or
granted herein shall be a Saturday, Sunday or a legal holiday, then such
action may be taken or such right may be exercised on the next succeeding day
not a Saturday, Sunday or legal holiday.

         11.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.

                  (a)  ADJUSTMENT AFTER 180 DAYS.  The Exercise Price shall
be adjusted to equal 110% of the five day average of the closing bid prices
of the Common Stock calculated on the 180th day after the date of issuance of
this Warrant, if such adjusted Exercise Price would be lower than the initial
Exercise Price (adjusted for any stock splits etc.), and otherwise shall
remain at the initial Exercise Price.

                  (b)  STOCK SPLITS, ETC.  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 of Common Stock, (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 of this Warrant shall be entitled to receive the kind and number of
Warrant Shares or other securities of the Company which he 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 of this Warrant 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.

                  (c)  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

                                       4
<PAGE>

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 Holder shall have the right thereafter to receive, upon
exercise of this Warrant, the number of shares of common stock of the
successor or acquiring corporation or of the Company, if it is the surviving
corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of
assets by a holder of the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to such event. 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 in writing or by operation of law 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 shares of
Common Stock for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 11.
For purposes of this Section 11, "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 11 shall similarly apply to
successive reorganizations, reclassifications, mergers, consolidations or
disposition of assets.

         12.  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.

         13.  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 promptly mail by registered or certified mail, return receipt
requested, to the holder of this Warrant notice of such adjustment or
adjustments setting forth 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. Such notice, in the absence of manifest error, shall be conclusive
evidence of the correctness of such adjustment.

                                       5
<PAGE>

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

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

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

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

then, in any one or more of such cases, the Company shall give to Holder (i)
at least 10 days' prior written notice of the record date 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 expected 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 shares of Common Stock 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 16(d).

         15.  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 Principal Market upon which the Common Stock may be
listed.

                  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

                                       6
<PAGE>

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 against impairment. Without
limiting the generality of the foregoing, the Company will (a) not increase
the par value of any shares of Common Stock receivable upon the exercise of
this Warrant 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 shares of Common Stock upon the exercise
of this Warrant, and (c) use its best 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.

                  Upon the request of Holder, the Company will at any time
during the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant
and the obligations of the Company hereunder.

                  Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company
shall take any corporate action which may be necessary in order that the
Company may validly and legally issue fully paid and non-assessable shares of
such Common Stock at such adjusted Exercise Price.

                  Before taking any action which would result in an
adjustment in the number of shares of Common Stock 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.

         16.  MISCELLANEOUS.

                  (a)  JURISDICTION.  This Warrant shall constitute a
contract under the laws of New York without regard to its conflict of law,
principles or rules, and be subject to arbitration pursuant to the terms set
forth in the Purchase Agreement.

                  (b)  RESTRICTIONS.  The holder hereof 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 fails to comply with any provision of this
Warrant, 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.

                                       7
<PAGE>

                  (d)  NOTICES.  Any notice, request or other document
required or permitted to be given or delivered to the holder hereof by the
Company shall be delivered in accordance with the notice provisions of the
Purchase Agreement.

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

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

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

                  (h)  INDEMNIFICATION.  The Company agrees to indemnify and
hold harmless Holder from and against any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, attorneys'
fees, expenses and disbursements of any kind which may be imposed upon,
incurred by or asserted against Holder in any manner relating to or arising
out of any failure by the Company to perform or observe in any material
respect any of its covenants, agreements, undertakings or obligations set
forth in this Warrant; PROVIDED, HOWEVER, that the Company will not be liable
hereunder to the extent that any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees,
expenses or disbursements are found in a final non-appealable judgment by a
court to have resulted from Holder's negligence, bad faith or willful
misconduct in its capacity as a stockholder or warrantholder of the Company.

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

                  (j)  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.

                  (k)  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.

representative capacity should file proper evidence of authority to assign
the foregoing Warrant.

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT, dated as of January 17, 2000,
between the investor or investors signatory hereto (each an "Investor" and
together the "Investors"), and Eco Soil Systems, Inc., a Nebraska corporation
(the "Company").

         WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Investors are purchasing from the Company, pursuant to a
Convertible Debentures and Warrants Purchase Agreement dated the date hereof
(the "Purchase Agreement"), $4,500,000 principal amount of Convertible
Debentures and Warrants to purchase shares of the Company's Common Stock
(terms not defined herein shall have the meanings ascribed to them in the
Purchase Agreement); and

         WHEREAS, the Company desires to grant to the Investors the
registration rights set forth herein with respect to the Conversion Shares of
Common Stock issuable upon conversion of the Convertible Debentures purchased
pursuant to the Purchase Agreement or issued as interest thereon, and shares
of Common Stock issuable upon exercise of the Warrants (hereinafter referred
to as the "Stock" or "Securities" of the Company).

         NOW, THEREFORE, the parties hereto mutually agree as follows:

         Section 1.  REGISTRABLE SECURITIES.  As used herein the term
"Registrable Security" means the Securities until (i) the Registration
Statement has been declared effective by the SEC, and all Securities have
been disposed of pursuant to the Registration Statement, (ii) all Securities
have been sold under circumstances under which all of the applicable
conditions of Rule 144 (or any similar provision then in force) under the
Securities Act ("Rule 144") are met, (iii) all Securities have been otherwise
transferred to holders who may trade such Securities without restriction
under the Securities Act, and the Company has delivered a new certificate or
other evidence of ownership for such Securities not bearing a restrictive
legend or (iv) such time as, in the opinion of counsel to the Company, all
Securities may be sold within a three-month period pursuant to Rule 144 (or
any similar provision then in effect). The term "Registrable Securities"
means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security." In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be deemed to be
made in the definition of "Registrable Security" as is appropriate in order
to prevent any dilution or enlargement of the rights granted pursuant to this
Agreement.

         Section 2.  RESTRICTIONS ON TRANSFER.  Each Investor acknowledges
and understands that prior to the registration of the Securities as provided
herein, the Securities are "restricted securities" as defined in Rule 144
promulgated under the Act. Each Investor understands that no disposition or
transfer of the Securities may be made by Investor in the absence of (i) an
opinion of counsel to the Investor, in form and substance reasonably
satisfactory to the Company, that such transfer may be made without
registration under the Securities Act or (ii) such registration.

<PAGE>

                  With a view to making available to the Investors the
benefits of Rule 144 under the Securities Act or any other similar rule or
regulation of the SEC that may at any time permit the Investors to sell
securities of the Company to the public without registration ("Rule 144"),
the Company agrees to:

                  (a)  comply with the provisions of paragraph (c)(1) of Rule
144; and

                  (b)  file with the SEC in a timely manner all reports and
other documents required to be filed with the SEC pursuant to Section 13 or
15(d) under the Exchange Act by companies subject to either of such sections,
irrespective of whether the Company is then subject to such reporting
requirements.

         Section 3.  REGISTRATION RIGHTS WITH RESPECT TO THE SECURITIES.

                  (a)  The Company agrees that it will prepare and file with
the SEC, at the earliest opportunity, but in no event later than the earlier
of forty-five (45) days after the Closing Date or the filing of another
registration statement for another purpose on a form which would allow
registration of the Registrable Securities sold at the Closing, a
registration statement (on Form S-3, or other appropriate registration
statement form) under the Securities Act (the "Registration Statement"), at
the sole expense of the Company (except as provided in Section 3(c) hereof),
in respect of the Investors, so as to permit a public offering and resale of
the Securities issuable in connection with the Convertible Debentures and
Warrants under the Act by the Investors as selling stockholders and not as
underwriters.

                  The Company shall use its best efforts to cause the
Registration Statement to become effective within ninety (90) days from the
Closing Date (or 120 days if such Registration Statement receives a "full
review" from the SEC staff, which shall not include a "plain English" or
"Plan of Distribution" review), or, if earlier, within five (5) days of SEC
clearance to request acceleration of effectiveness. The number of shares
designated in the Registration Statement to be registered shall include all
the Warrant Shares, at least the number of shares initially issuable upon
conversion of the Convertible Debentures at the minimum Conversion Price, and
such number of shares as the Company deems prudent for the purpose of issuing
shares of Common Stock as interest on the Convertible Debentures, and shall
include appropriate language regarding reliance upon Rule 416 to the extent
permitted by the SEC. The Company will notify the Investors of the
effectiveness of each Registration Statement within one Trading Day of such
event.

                  (b)  The Company will maintain the Registration Statement
or post-effective amendment filed under this Section 3 effective under the
Securities Act until the earlier of (i) the date that none of the Securities
covered by such Registration Statement are or may become issued and
outstanding, (ii) the date that all of the Securities have been sold pursuant
to such Registration Statement, (iii) the date that all of the Securities
that have not been sold thereunder may be sold under the provisions of Rule
144 within a three-month period, (iv) all Securities have been otherwise
transferred to persons who may trade such shares without restriction under
the Securities Act, and the Company has delivered a new certificate or other

                                       2
<PAGE>

evidence of ownership for such securities not bearing a restrictive legend,
or (v) all Securities may be sold without any time, volume or manner
limitations pursuant to Rule 144(k) or any similar provision then in effect
under the Securities Act (the "Effectiveness Period").

                  (c)  All fees, disbursements and out-of-pocket expenses and
costs incurred by the Company in connection with the preparation and filing
of the Registration Statement under subparagraph 3(a) and in complying with
applicable securities and Blue Sky laws (including, without limitation, all
attorneys' fees of the Company) shall be borne by the Company. The Investors
shall bear the cost of underwriting and/or brokerage discounts, fees and
commissions, if any, applicable to the Securities being registered and the
fees and expenses of their counsel. The Investors and their counsel shall
have a reasonable period, not to exceed five (5) Trading Days, to review the
proposed Registration Statement or any amendment thereto, prior to filing
with the SEC, and the Company shall provide each Investor with copies of any
comment letters received from the SEC with respect thereto within two (2)
Trading Days of receipt thereof. The Company shall qualify any of the
securities for sale in such states as any Investor reasonably designates and
shall furnish indemnification in the manner provided in Section 6 hereof.
However, the Company shall not be required to qualify in any state which will
require an escrow or other restriction relating to the Company and/or the
sellers, or which will require the Company to qualify to do business in such
state or require the Company to file therein any general consent to service
of process. The Company at its expense will supply the Investors with copies
of the Registration Statement and the prospectus included therein and other
related documents in such quantities as may be reasonably requested by the
Investors.

                  (d)  The Company shall not be required by this Section 3 to
include an Investor's Securities in any Registration Statement which is to be
filed if, in the opinion of counsel for both the Investor and the Company
(or, should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Investor and the
Company) the proposed offering or other transfer as to which such
registration is requested is exempt from applicable federal and state
securities laws and would result in all purchasers or transferees obtaining
securities which are not "restricted securities", as defined in Rule 144
under the Securities Act.

                  (e)  In the event that (i) the Registration Statement is
not filed with the SEC within forty-five (45) days from the Closing Date,
(ii) such Registration Statement is not declared effective by the SEC within
the earlier of ninety (90) days from the Closing Date (or 120 days in the
event of a "full review") or five (5) days of clearance by the SEC to request
effectiveness, or (iii) such Registration Statement is not maintained as
effective by the Company for the period set forth in Section 3(b) above and
subject to Section 3(g) below (each a "Registration Default") then the
Company will pay Investor (pro rated on a daily basis), as liquidated damages
for such failure and not as a penalty two percent (2%) of the aggregate
market value of shares of Common Stock purchased from the Company (including
the Conversion Shares which would be issuable upon conversion of the
Convertible Debentures on any date of determination, and whether or not the
Convertible Debentures are then convertible pursuant to their terms) and held
by the Investor for the first month and three percent (3%) for every month
thereafter until such Registration Statement has been filed, and in the event
of late effectiveness (in case of clause (ii) above) or lapsed effectiveness
(in the case of clause (iii)

                                       3
<PAGE>

above), two percent (2%) of the aggregate market value of shares of Common
Stock purchased from the Company and held by the Investor (including the
Conversion Shares which would be issuable upon conversion of the Convertible
Debentures on any date of determination, and whether or not the Convertible
Debentures are then convertible pursuant to their terms) for the first month
and three percent (3%) for every month thereafter (provided only one set of
liquidated damages shall be payable whether one or more such Registration
Defaults are then in existence) until such Registration Statement has been
declared effective. Such payment of the liquidated damages shall be made to
the Investors in cash, within five (5) calendar days of demand, provided,
however, that the payment of such liquidated damages shall not relieve the
Company from its obligations to register the Securities pursuant to this
Section. The market value of the Common Stock for this purpose shall be the
closing price (or last trade, if so reported) on the Principal Market for
each day during such Registration Default.

                  If the Company does not remit the payment to the Investors
as set forth above, the Company will pay the Investors reasonable costs of
collection, including attorneys' fees, in addition to the liquidated damages.
The registration of the Securities pursuant to this provision shall not
affect or limit the Investors' other rights or remedies as set forth in this
Agreement.

                  (f)  The Company shall not include any securities other
than the Registrable Securities in any Registration Statement which it is
required to file pursuant to this Section 3, except with the prior written
consent of all Investors, other than (i) 402,208 shares held by Albion
Alliance Mezzanine Fund LP and Paribas Capital Funding LLC, provided that
such holders shall have agreed in writing with the Company and the Investors
that they shall not sell more than 100,000 shares every ninety (90) days from
the Effective Date, and their stock certificates shall have been legended to
such effect, (ii) up to one million shares privately issued to other
institutional investors, provided such other transaction closes within the
initial filing deadline provided for herein and does not cause any delay in
the filing of the Registration Statement and (iii) other issued and
outstanding shares of Common Stock and shares of Common Stock issuable upon
exercise of issued and outstanding warrants and options, held by persons with
rights to require the inclusion of such shares in the Registration Statement,
but, except as set forth in clause (i) above, not including shares held by or
issuable to Albion or Paribas.

                  (g)  If at any time or from time to time after the
effective date of the Registration Statement, the Company notifies the
Investors in writing of the existence of a Potential Material Event (as
defined in Section 3(h) below), the Investors shall not offer or sell any
Securities or engage in any other transaction involving or relating to
Securities, from the time of the giving of notice with respect to a Potential
Material Event until the Investors receive written notice from the Company
that such Potential Material Event either has been disclosed to the public or
no longer constitutes a Potential Material Event; provided, however, that the
Company may not so suspend the right to such holders of Securities for more
than twenty (20) days in the aggregate during any twelve month period, during
the period the Registration Statement is required to be in effect, without
such event being a Registration Default. If a Potential Material Event shall
occur prior to the date the Registration Statement is required to be filed,
then the Company's obligation to file the Registration Statement shall be
delayed without penalty for not more than thirty (30) days, and such delay or
delays shall not constitute a

                                       4
<PAGE>

Registration Default. The Company must, if lawful, give the Investors notice
in writing at least two (2) Trading Days prior to the first day of the
blackout period.

                  (h)  "Potential Material Event" means any of the following:
(a) the possession by the Company of material information not ripe for
disclosure in a registration statement, as determined in good faith by the
Chief Executive Officer or the Board of Directors of the Company that
disclosure of such information in a Registration Statement would be
detrimental to the business and affairs of the Company; or (b) any material
engagement or activity by the Company which would, in the good faith
determination of the Chief Executive Officer or the Board of Directors of the
Company, be adversely affected by disclosure in a registration statement at
such time, which determination shall be accompanied by a good faith
determination by the Chief Executive Officer or the Board of Directors of the
Company that the applicable Registration Statement would be materially
misleading absent the inclusion of such information.

         Section 4.  COOPERATION WITH COMPANY.  The Investors will cooperate
with the Company in all respects in connection with this Agreement, including
timely supplying all information reasonably requested by the Company (which
shall include all information regarding the Investors and proposed manner of
sale of the Registrable Securities required to be disclosed in the
Registration Statement) and executing and returning all documents reasonably
requested in connection with the registration and sale of the Registrable
Securities and entering into and performing their obligations under any
underwriting agreement, if the offering is an underwritten offering, in usual
and customary form, with the managing underwriter or underwriters of such
underwritten offering. Nothing in this Agreement shall obligate any Investor
to consent to be named as an underwriter in any Registration Statement. The
obligation of the Company to register all of the Registrable Securities shall
be absolute and unconditional as to those Securities which the SEC will
permit to be registered without naming the Investors as underwriters.

         Section 5.  REGISTRATION PROCEDURES.  If and whenever the Company is
required by any of the provisions of this Agreement to effect the
registration of any of the Registrable Securities under the Act, the Company
shall (except as otherwise provided in this Agreement), as expeditiously as
possible, subject to the Investors' assistance and cooperation as reasonably
required with respect to the Registration Statement:

                  (a)  (i) prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in
connection therewith as may be necessary to keep such Registration Statement
effective and to comply with the provisions of the Act with respect to the
sale or other disposition of all securities covered by such registration
statement whenever the Investors shall desire to sell or otherwise dispose of
the same (including prospectus supplements with respect to the sales of
securities from time to time in connection with a registration statement
pursuant to Rule 415 promulgated under the Act) and (ii) take all lawful
action such that each of (A) the Registration Statement and any amendment
thereto does not, when it becomes effective, 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 and (B) the prospectus forming
part of the Registration Statement, and any amendment or supplement thereto,
does not at any

                                       5
<PAGE>

time during the Registration Period include 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;

                  (b)  (i) prior to the filing with the SEC of any
Registration Statement (including any amendments thereto) and the
distribution or delivery of any prospectus (including any supplements
thereto), provide draft copies thereof to the Investors as required by
Section 3(c) and reflect in such documents all such comments as the Investors
(and their counsel) reasonably may propose respecting the Selling
Shareholders and Plan of Distribution sections (or equivalents) and (ii)
furnish to each Investor such numbers of copies of a prospectus including a
preliminary prospectus or any amendment or supplement to any prospectus, as
applicable, in conformity with the requirements of the Act, and such other
documents, as such Investor may reasonably request in order to facilitate the
public sale or other disposition of the securities owned by such Investor;

                  (c)  register and qualify the Registrable Securities
covered by the Registration Statement under such other securities or blue sky
laws of such jurisdictions as the Investors shall reasonably request (subject
to the limitations set forth in Section 3(c) above), and do any and all other
acts and things which may be necessary or advisable to enable each Investor
to consummate the public sale or other disposition in such jurisdiction of
the securities owned by such Investor;

                  (d)  list such Registrable Securities on the Principal
Market, if the listing of such Registrable Securities is then permitted under
the rules of such Principal Market;

                  (e)  notify each Investor at any time when a prospectus
relating thereto covered by the Registration Statement is required to be
delivered under the Act, of the happening of any event of which it has
knowledge as a result of which the prospectus included in the Registration
Statement, as then in effect, includes 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 not misleading in the light of the
circumstances then existing, and the Company shall prepare and file a
curative amendment under Section 5(a) as quickly as commercially possible;

                  (f)  as promptly as practicable after becoming aware of
such event, notify each Investor who holds Registrable Securities being sold
(or, in the event of an underwritten offering, the managing underwriters) of
the issuance by the SEC of any stop order or other suspension of the
effectiveness of the Registration Statement at the earliest possible time and
take all lawful action to effect the withdrawal, recession or removal of such
stop order or other suspension;

                  (g)  cooperate with the Investors to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates
for the Registrable Securities to be in such denominations or amounts, as the
case may be, as the Investors reasonably may request and registered in such
names as the Investors may request; and, within three (3) Trading Days after
a Registration Statement which includes Registrable Securities is declared
effective by the SEC, deliver and

                                       6
<PAGE>

cause legal counsel selected by the Company to deliver to the transfer agent
for the Registrable Securities (with copies to the Investors) an appropriate
instruction and, to the extent necessary, an opinion of such counsel;

                  (h)  take all such other lawful actions reasonably
necessary to expedite and facilitate the disposition by the Investors of
their Registrable Securities in accordance with the intended methods therefor
provided in the prospectus which are customary for issuers to perform under
the circumstances;

                  (i)  in the event of an underwritten offering, promptly
include or incorporate in a prospectus supplement or post-effective amendment
to the Registration Statement such information as the managers reasonably
agree should be included therein and to which the Company does not reasonably
object and make all required filings of such prospectus supplement or
post-effective amendment as soon as practicable after it is notified of the
matters to be included or incorporated in such Prospectus supplement or
post-effective amendment; and

                  (j)  maintain a transfer agent and registrar for its Common
Stock.

         Section 6.  INDEMNIFICATION.

                   (a)  To the maximum extent permitted by law, the Company
agrees to indemnify and hold harmless the Investors and each person, if any,
who controls an Investor within the meaning of the Securities Act (each a
"Distributing Investor") against any losses, claims, damages or liabilities,
joint or several (which shall, for all purposes of this Agreement, include,
but not be limited to, all reasonable costs of defense and investigation and
all reasonable attorneys' fees and expenses), to which the Distributing
Investor may become subject, under the Securities Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration
Statement, or any related final prospectus or amendment or supplement
thereto, or arise out of or are based upon 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
Company will not be liable in any such case to the extent, and only to the
extent, that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such Registration Statement, preliminary prospectus,
final prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by the
Distributing Investor, its counsel, affiliates or any underwriter,
specifically for use in the preparation thereof. In addition, the Company
shall not be liable hereunder to the extent a Distributing Investor caused
such losses etc. by failing to deliver the final prospectus or any amendment
or supplement thereto. This indemnity agreement will be in addition to any
liability which the Company may otherwise have.

                  (b)  To the maximum extent permitted by law, each
Distributing Investor agrees that it will indemnify and hold harmless the
Company, and each officer and director of the Company or person, if any, who
controls the Company within the meaning of the Securities Act, against any
losses, claims, damages or liabilities (which shall, for all purposes of

                                       7
<PAGE>

this Agreement, include, but not be limited to, all reasonable costs of
defense and investigation and all reasonable attorneys' fees and expenses) to
which the Company or any such officer, director or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, or any related final
prospectus or amendment or supplement thereto, or arise out of or are based
upon (i) failure by such Distributing Investor to deliver the final
prospectus or any amendment or supplement thereto, or (ii) the omission or
the alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, but in
each case only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in such Registration
Statement, final prospectus or amendment or supplement thereto in reliance
upon, and in conformity with, written information furnished to the Company by
such Distributing Investor, its counsel, affiliates or any underwriter,
specifically for use in the preparation thereof. This indemnity agreement
will be in addition to any liability which the Distributing Investor may
otherwise have.

                  (c)  Promptly after receipt by an indemnified party under
this Section 6 of notice of the commencement of any action against such
indemnified party, such indemnified party will, if a claim in respect thereof
is to be made against the indemnifying party under this Section 6, notify the
indemnifying party in writing of the commencement thereof; but the omission
so to notify the indemnifying party will not relieve the indemnifying party
from any liability which it may have to any indemnified party except to the
extent the failure of the indemnified party to provide such written
notification actually prejudices the ability of the indemnifying party to
defend such action. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate in, and, to
the extent that it may wish, jointly with any other indemnifying party
similarly notified, assume the defense thereof, subject to the provisions
herein stated and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section 6 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless the indemnifying party shall not
pursue the action to its final conclusion. The indemnified parties as a group
shall have the right to employ one separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying
party has assumed the defense of the action with counsel reasonably
satisfactory to the indemnified party unless (i) the employment of such
counsel has been specifically authorized in writing by the indemnifying
party, or (ii) the named parties to any such action (including any impleaded
parties) include both the indemnified party and the indemnifying party and
the indemnified party shall have been advised by its counsel that there may
be one or more legal defenses available to the indemnifying party different
from or in conflict with any legal defenses which may be available to the
indemnified party or any other indemnified party (in which case the
indemnifying party shall not have the right to assume the defense of such
action on behalf of such indemnified party, it being understood, however,
that the indemnifying party shall, in connection with any one such action or
separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable only for the reasonable fees and expenses of

                                       8
<PAGE>

one separate firm of attorneys for the indemnified party, which firm shall be
designated in writing by the indemnified party). No settlement of any action
against an indemnified party shall be made without the prior written consent
of the indemnified party, which consent shall not be unreasonably withheld so
long as such settlement includes a full release of claims against the
indemnified party.

         Section 7.  CONTRIBUTION.  In order to provide for just and
equitable contribution under the Securities Act in any case in which (i) the
indemnified party makes a claim for indemnification pursuant to Section 6
hereof but is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to
appeal or the denial of the last right of appeal) that such indemnification
may not be enforced in such case notwithstanding the fact that the express
provisions of Section 6 hereof provide for indemnification in such case, or
(ii) contribution under the Securities Act may be required on the part of any
indemnified party, then the Company and the applicable Distributing Investor
shall contribute to the aggregate losses, claims, damages or liabilities to
which they may be subject (which shall, for all purposes of this Agreement,
include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees and expenses), in either
such case (after contribution from others) on the basis of relative fault as
well as any other relevant equitable considerations. The relative fault 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 on the one hand or the applicable Distributing Investor on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Distributing Investor agree that it would not be just and equitable if
contribution pursuant to this Section 7 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 this Section 7. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in
this Section 7 shall be deemed to include any reasonable legal or other
expenses reasonably incurred by such indemnified party in connection with

received by such Investor from the sale of such Investor's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Registration Statement under which such Registrable
Securities are registered under the Securities Act and (ii) underwriter be
required to undertake liability to any person hereunder for any amounts in
excess of the aggregate discount, commission or other compensation payable to
such underwriter with respect to the Registrable Securities underwritten by
it and distributed pursuant to such Registration Statement.

impaired or invalidated, and the parties hereto shall use their best 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.

or otherwise prevents the Company from complying with all of its obligations
hereunder.

         Section 14.  HEADINGS.  The headings in this Agreement are for

governed by and construed in accordance with the laws of the State of New
York applicable to contracts made in New York by persons domiciled in New
York City and without regard to its principles of conflicts of laws. Any
dispute under this Agreement shall be submitted to arbitration under the
American Arbitration Association (the "AAA") in New York City, New York, and
shall be finally and conclusively determined by the decision of a board of
arbitration consisting of three (3)

members (hereinafter referred to as the "Board of Arbitration") selected as
according to the rules governing the AAA. The Board of Arbitration shall meet
on consecutive business days in New York City, New York, and shall reach and
render a decision in writing (concurred in by a majority of the members of
the Board of Arbitration) with respect to the amount, if any, which the
losing party is required to pay to the other party in respect of a claim
filed. In connection with rendering its decisions, the Board of Arbitration
shall adopt and follow the laws of the State of New York. To the extent
practical, decisions of the Board of Arbitration shall be rendered no more
than thirty (30) calendar days following commencement of proceedings with
respect thereto. The Board of Arbitration shall cause its written decision to
be delivered to all parties involved in the dispute. Any decision made by the
Board of Arbitration (either prior to or after the expiration of such thirty
(30) calendar day period) shall be final, binding and conclusive on the
parties to the dispute, and entitled to be enforced to the fullest extent
permitted by law and entered in any court of competent jurisdiction. The
Board of Arbitration shall be authorized and is hereby directed to enter a
default judgment against any party failing to participate in any proceeding
hereunder within the time periods set forth in the AAA rules. The
non-prevailing party to any arbitration (as determined by the Board of
Arbitration) shall pay the expenses of the prevailing party, including
reasonable attorneys' fees, in connection with such arbitration. Any party
shall be entitled to obtain injunctive relief from a court in any case where
such relief is available. The non-prevailing party to any injunctive
proceeding (as determined by the court) shall pay the expenses of the
prevailing party, including reasonable attorneys' fees, in connection with
such injunctive proceeding.
