EXHIBIT 10.10

      THIS WARRANT AND THE SHARES ISSUABLE UPON THE EXERCISE OF THIS WARRANT
      HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
      EXCEPT AS OTHERWISE SET FORTH HEREIN OR IN A SECURITIES PURCHASE AGREEMENT
      DATED AS OF JUNE 16, 2008, NEITHER THIS WARRANT NOR ANY OF SUCH SHARES MAY
      BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
      REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER SAID ACT OR, AN OPINION
      OF COUNSEL, IN FORM, SUBSTANCE AND SCOPE, CUSTOMARY FOR OPINIONS OF
      COUNSEL IN COMPARABLE TRANSACTIONS, THAT REGISTRATION IS NOT REQUIRED

      SUCH ACT.

                                             Right to Purchase 12,000,000 Shares
                                               of Common Stock, no par value per
                                                                           share

                             STOCK PURCHASE WARRANT

      THIS CERTIFIES THAT, for value received, New Millennium Capital Partners
II, LLC or its registered assigns, is entitled to purchase from Ingen
Technologies, Inc., a Georgia corporation (the "Company"), at any time or from
time to time during the period specified in Paragraph 2 hereof, 12,000,000 fully
paid and nonassessable shares of the Company's Common Stock, no par value per
share (the "Common Stock"), at an exercise price per share equal to $.001 (the
"Exercise Price"). The term "Warrant Shares," as used herein, refers to the
shares of Common Stock purchasable hereunder. The Warrant Shares and the
Exercise Price are subject to adjustment as provided in Paragraph 4 hereof. The
term "Warrants" means this Warrant and the other warrants issued pursuant to
that certain Securities Purchase Agreement, dated June 16, 2008, by and among
the Company and the Buyers listed on the execution page thereof (the "Securities
Purchase Agreement").

      This Warrant is subject to the following terms, provisions, and
conditions:

      1.    MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.
Subject to the provisions hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant, together with a
completed exercise agreement in the form attached hereto (the "Exercise
Agreement"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the

<PAGE>

Company as it may designate by notice to the holder hereof), and upon (i)
payment to the Company in cash, by certified or official bank check or by wire
transfer for the account of the Company of the Exercise Price for the Warrant
Shares specified in the Exercise Agreement or (ii) if the resale of the Warrant
Shares by the holder is not then registered pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), delivery to the Company of a written notice of an election to
effect a "Cashless Exercise" (as defined in Section 11(c) below) for the Warrant
Shares specified in the Exercise Agreement. The Warrant Shares so purchased
shall be deemed to be issued to the holder hereof or such holder's designee, as
the record owner of such shares, as of the close of business on the date on
which this Warrant shall have been surrendered, the completed Exercise Agreement
shall have been delivered, and payment shall have been made for such shares as
set forth above. Certificates for the Warrant Shares so purchased, representing
the aggregate number of shares specified in the Exercise Agreement, shall be
delivered to the holder hereof within a reasonable time, not exceeding five (5)
business days, after this Warrant shall have been so exercised. The certificates
so delivered shall be in such denominations as may be requested by the holder
hereof and shall be registered in the name of such holder or such other name as
shall be designated by such holder. If this Warrant shall have been exercised
only in part, then, unless this Warrant has expired, the Company shall, at its
expense, at the time of delivery of such certificates, deliver to the holder a
new Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised. In addition to all other available remedies
at law or in equity, if the Company fails to deliver certificates for the
Warrant Shares within five (5) business days after this Warrant is exercised,
then the Company shall pay to the holder in cash a penalty (the "Penalty") equal
to 2% of the number of Warrant Shares that the holder is entitled to multiplied
by the Market Price (as hereinafter defined) for each day that the Company fails
to deliver certificates for the Warrant Shares. For example, if the holder is
entitled to 100,000 Warrant Shares and the Market Price is $2.00, then the
Company shall pay to the holder $4,000 for each day that the Company fails to
deliver certificates for the Warrant Shares. The Penalty shall be paid to the
holder by the fifth day of the month following the month in which it has
accrued.

      Notwithstanding anything in this Warrant to the contrary, in no event
shall the holder of this Warrant be entitled to exercise a number of Warrants
(or portions thereof) in excess of the number of Warrants (or portions thereof)
upon exercise of which the sum of (i) the number of shares of Common Stock
beneficially owned by the holder and its affiliates (other than shares of Common
Stock which may be deemed beneficially owned through the ownership of the
unexercised Warrants and the unexercised or unconverted portion of any other
securities of the Company (including the Notes (as defined in the Securities
Purchase Agreement)) subject to a limitation on conversion or exercise analogous
to the limitation contained herein) and (ii) the number of shares of Common
Stock issuable upon exercise of the Warrants (or portions thereof) with respect
to which the determination described herein is being made, would result in
beneficial ownership by the holder and its affiliates of more than 4.9% of the
outstanding shares of Common Stock. For purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G
thereunder, except as otherwise provided in clause (i) of the preceding
sentence. Notwithstanding anything to the contrary contained herein, the
limitation on exercise of this Warrant set forth herein may not be amended
without (i) the written consent of the holder hereof and the Company and (ii)
the approval of a majority of shareholders of the Company.

                                      -2-

      2.    PERIOD OF EXERCISE. This Warrant is exercisable at any time or from
time to time on or after the date on which this Warrant is issued and delivered
pursuant to the terms of the Securities Purchase Agreement and before 6:00 p.m.,
New York, New York time on the seventh (7th) anniversary of the date of issuance
(the "Exercise Period").

      3.    CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants and
agrees as follows:

            (A)   SHARES TO BE FULLY PAID. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid, and nonassessable and free from all taxes, liens, and charges with respect
to the issue thereof.

            (B)   RESERVATION OF SHARES. During the Exercise Period, the Company
shall at all times have authorized, and reserved for the purpose of issuance
upon exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

            (C)   LISTING. The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of the Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

            (D)   CERTAIN ACTIONS PROHIBITED. The Company will not, by amendment
of its charter 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 to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock receivable upon
the exercise of this Warrant above the Exercise Price then in effect, and (ii)
will take all such actions 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.

            (E)   SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

      4.    ANTIDILUTION PROVISIONS. During the Exercise Period, the Exercise
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Paragraph 4.

                                      -3-
<PAGE>

      In the event that any adjustment of the Exercise Price as required herein
results in a fraction of a cent, such Exercise Price shall be rounded up to the
nearest cent.

            (A)   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES UPON
ISSUANCE OF COMMON STOCK. Except as otherwise provided in Paragraphs 4(c) and
4(e) hereof, if and whenever on or after the date of issuance of this Warrant,
the Company issues or sells, or in accordance with Paragraph 4(b) hereof is
deemed to have issued or sold, any shares of Common Stock for no consideration
or for a consideration per share (before deduction of reasonable expenses or
commissions or underwriting discounts or allowances in connection therewith)
less than the Market Price on the date of issuance (a "Dilutive Issuance"), then
immediately upon the Dilutive Issuance, the Exercise Price will be reduced to a
price determined by multiplying the Exercise Price in effect immediately prior
to the Dilutive Issuance by a fraction, (i) the numerator of which is an amount
equal to the sum of (x) the number of shares of Common Stock actually
outstanding immediately prior to the Dilutive Issuance, plus (y) the quotient of
the aggregate consideration, calculated as set forth in Paragraph 4(b) hereof,
received by the Company upon such Dilutive Issuance divided by the Market Price
in effect immediately prior to the Dilutive Issuance, and (ii) the denominator
of which is the total number of shares of Common Stock Deemed Outstanding (as
defined below) immediately after the Dilutive Issuance.

            (B)   EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS. For purposes of
determining the adjusted Exercise Price under Paragraph 4(a) hereof, the
following will be applicable:

                  (I)   ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities convertible into or exchangeable for Common Stock ("Convertible
Securities") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "Options") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Market Price on the date of issuance or grant of such Options,
then the maximum total number of shares of Common Stock issuable upon the
exercise of all such Options will, as of the date of the issuance or grant of
such Options, be deemed to be outstanding and to have been issued and sold by
the Company for such price per share. For purposes of the preceding sentence,
the "price per share for which Common Stock is issuable upon the exercise of
such Options" is determined by dividing (i) the total amount, if any, received
or receivable by the Company as consideration for the issuance or granting of
all such Options, plus the minimum aggregate amount of additional consideration,
if any, payable to the Company upon the exercise of all such Options, plus, in
the case of Convertible Securities issuable upon the exercise of such Options,
the minimum aggregate amount of additional consideration payable upon the
conversion or exchange thereof at the time such Convertible Securities first
become convertible or exchangeable, by (ii) the maximum total number of shares
of Common Stock issuable upon the exercise of all such Options (assuming full
conversion of Convertible Securities, if applicable). No further adjustment to
the Exercise Price will be made upon the actual issuance of such Common Stock
upon the exercise of such Options or upon the conversion or exchange of
Convertible Securities issuable upon exercise of such Options.

                  (II)  ISSUANCE OF CONVERTIBLE SECURITIES. If the Company in
any manner issues or sells any Convertible Securities, whether or not
immediately convertible (other than where the same are issuable upon the

                                      -4-
<PAGE>

exercise of Options) and the price per share for which Common Stock is issuable
upon such conversion or exchange is less than the Market Price on the date of
issuance, then the maximum total number of shares of Common Stock issuable upon
the conversion or exchange of all such Convertible Securities will, as of the
date of the issuance of such Convertible Securities, be deemed to be outstanding
and to have been issued and sold by the Company for such price per share. For
the purposes of the preceding sentence, the "price per share for which Common
Stock is issuable upon such conversion or exchange" is determined by dividing
(i) the total amount, if any, received or receivable by the Company as
consideration for the issuance or sale of all such Convertible Securities, plus
the minimum aggregate amount of additional consideration, if any, payable to the
Company upon the conversion or exchange thereof at the time such Convertible
Securities first become convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible Securities. No further adjustment to the Exercise Price will be
made upon the actual issuance of such Common Stock upon conversion or exchange
of such Convertible Securities.

                  (III) CHANGE IN OPTION PRICE OR CONVERSION RATE. If there is a
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the conversion or exchange of
any Convertible Securities; or (iii) the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock (other than
under or by reason of provisions designed to protect against dilution), the
Exercise Price in effect at the time of such change will be readjusted to the
Exercise Price which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold.

                  (IV)  TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED CONVERTIBLE
SECURITIES. If, in any case, the total number of shares of Common Stock issuable
upon exercise of any Option or upon conversion or exchange of any Convertible
Securities is not, in fact, issued and the rights to exercise such Option or to
convert or exchange such Convertible Securities shall have expired or
terminated, the Exercise Price then in effect will be readjusted to the Exercise
Price which would have been in effect at the time of such expiration or
termination had such Option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination (other than in respect of
the actual number of shares of Common Stock issued upon exercise or conversion
thereof), never been issued.

                  (V)   CALCULATION OF CONSIDERATION RECEIVED. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration part or all of which shall be other than cash, the amount of
the consideration other than cash received by the Company will be the fair value
of such consideration, except where such consideration consists of securities,
in which case the amount of consideration received by the Company will be the
Market Price thereof as of the date of receipt. In case any Common Stock,

                                      -5-
<PAGE>

Options or Convertible Securities are issued in connection with any acquisition,
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving corporation as is
attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair value of any consideration other than cash or securities
will be determined in good faith by the Board of Directors of the Company.

                  (VI)  EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE. No
adjustment to the Exercise Price will be made (i) upon the exercise of any
warrants, options or convertible securities granted, issued and outstanding on
the date of issuance of this Warrant; (ii) upon the grant or exercise of any
stock or options which may hereafter be granted or exercised under any employee
benefit plan, stock option plan or restricted stock plan of the Company now
existing or to be implemented in the future, so long as the issuance of such
stock or options is approved by a majority of the independent members of the
Board of Directors of the Company or a majority of the members of a committee of
independent directors established for such purpose; or (iii) upon the exercise
of the Warrants.

            (C)   SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company at
any time subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the shares of Common Stock
acquirable hereunder into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company at any
time combines (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) the shares of Common Stock acquirable hereunder
into a smaller number of shares, then, after the date of record for effecting
such combination, the Exercise Price in effect immediately prior to such
combination will be proportionately increased.

            (D)   ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
Exercise Price pursuant to the provisions of this Paragraph 4, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Warrant immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

            (E)   CONSOLIDATION, MERGER OR SALE. In case of any consolidation of
the Company with, or merger of the Company into any other corporation, or in
case of any sale or conveyance of all or substantially all of the assets of the
Company other than in connection with a plan of complete liquidation of the
Company, then as a condition of such consolidation, merger or sale or
conveyance, adequate provision will be made whereby the holder of this Warrant
will have the right to acquire and receive upon exercise of this Warrant in lieu
of the shares of Common Stock immediately theretofore acquirable upon the
exercise of this Warrant, such shares of stock, securities or assets as may be
issued or payable with respect to or in exchange for the number of shares of
Common Stock immediately theretofore acquirable and receivable upon exercise of
this Warrant had such consolidation, merger or sale or conveyance not taken
place. In any such case, the Company will make appropriate provision to insure
that the provisions of this Paragraph 4 hereof will thereafter be applicable as
nearly as may be in relation to any shares of stock or securities thereafter
deliverable upon the exercise of this Warrant. The Company will not effect any
consolidation, merger or sale or conveyance unless prior to the consummation
thereof, the successor corporation (if other than the Company) assumes by
written instrument the obligations under this Paragraph 4 and the obligations to
deliver to the holder of this Warrant such shares of stock, securities or assets
as, in accordance with the foregoing provisions, the holder may be entitled to
acquire.

                                      -6-
<PAGE>

            (F)   DISTRIBUTION OF ASSETS. In case the Company shall declare or
make any distribution of its assets (including cash) to holders of Common Stock
as a partial liquidating dividend, by way of return of capital or otherwise,
then, after the date of record for determining shareholders entitled to such
distribution, but prior to the date of distribution, the holder of this Warrant
shall be entitled upon exercise of this Warrant for the purchase of any or all
of the shares of Common Stock subject hereto, to receive the amount of such
assets which would have been payable to the holder had such holder been the
holder of such shares of Common Stock on the record date for the determination
of shareholders entitled to such distribution.

            (G)   NOTICE OF ADJUSTMENT. Upon the occurrence of any event which
requires any adjustment of the Exercise Price, then, and in each such case, the
Company shall give notice thereof to the holder of this Warrant, which notice
shall state the Exercise Price resulting from such adjustment and the increase
or decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the Chief Financial Officer of the Company.

            (H)   MINIMUM ADJUSTMENT OF EXERCISE PRICE. 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.

            (I)   NO FRACTIONAL SHARES. No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Market Price of a share of Common
Stock on the date of such exercise.

            (J)   OTHER NOTICES. In case at any time:

                  (I)   the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution
(including dividends or distributions payable in cash out of retained earnings)
to the holders of the Common Stock;

                  (II)  the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

                  (III) there shall be any capital reorganization of the
Company, or reclassification of the Common Stock, or consolidation or merger of
the Company with or into, or sale of all or substantially all its assets to,
another corporation or entity; or

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

                                      -7-
<PAGE>

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least 30 days
prior to the record date or the date on which the Company's books are closed in
respect thereto. Failure to give any such notice or any defect therein shall not
affect the validity of the proceedings referred to in clauses (i), (ii), (iii)
and (iv) above.

            (K)   CERTAIN EVENTS. If any event occurs of the type contemplated
by the adjustment provisions of this Paragraph 4 but not expressly provided for
by such provisions, the Company will give notice of such event as provided in
Paragraph 4(g) hereof, and the Company's Board of Directors will make an
appropriate adjustment in the Exercise Price and the number of shares of Common
Stock acquirable upon exercise of this Warrant so that the rights of the holder
shall be neither enhanced nor diminished by such event.

            (L)   CERTAIN DEFINITIONS.

                  (I)   "COMMON STOCK DEEMED OUTSTANDING" shall mean the number
of shares of Common Stock actually outstanding (not including shares of Common
Stock held in the treasury of the Company), plus (x) pursuant to Paragraph
4(b)(i) hereof, the maximum total number of shares of Common Stock issuable upon
the exercise of Options, as of the date of such issuance or grant of such
Options, if any, and (y) pursuant to Paragraph 4(b)(ii) hereof, the maximum
total number of shares of Common Stock issuable upon conversion or exchange of
Convertible Securities, as of the date of issuance of such Convertible
Securities, if any.

                  (II)  "MARKET PRICE," as of any date, (i) means the average of
the last reported sale prices for the shares of Common Stock on the OTCBB for
the five (5) Trading Days immediately preceding such date as reported by
Bloomberg, or (ii) if the OTCBB is not the principal trading market for the
shares of Common Stock, the average of the last reported sale prices on the
principal trading market for the Common Stock during the same period as reported
by Bloomberg, or (iii) if market value cannot be calculated as of such date on
any of the foregoing bases, the Market Price shall be the fair market value as
reasonably determined in good faith by (a) the Board of Directors of the Company
or, at the option of a majority-in-interest of the holders of the outstanding
Warrants by (b) an independent investment bank of nationally recognized standing
in the valuation of businesses similar to the business of the corporation. The
manner of determining the Market Price of the Common Stock set forth in the
foregoing definition shall apply with respect to any other security in respect
of which a determination as to market value must be made hereunder.

                                      -8-
<PAGE>

                  (III) "COMMON STOCK," for purposes of this Paragraph 4,
includes the Common Stock, no par value per share, and any additional class of
stock of the Company having no preference as to dividends or distributions on
liquidation, provided that the shares purchasable pursuant to this Warrant shall
include only shares of Common Stock, no par value per share, in respect of which
this Warrant is exercisable, or shares resulting from any subdivision or
combination of such Common Stock, or in the case of any reorganization,
reclassification, consolidation, merger, or sale of the character referred to in
Paragraph 4(e) hereof, the stock or other securities or property provided for in
such Paragraph.

      5.    ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

      6.    NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

      7.    TRANSFER, EXCHANGE, AND REPLACEMENT OF WARRANT.

            (A)   RESTRICTION ON TRANSFER. This Warrant and the rights granted
to the holder hereof are transferable, in whole or in part, upon surrender of
this Warrant, together with a properly executed assignment in the form attached
hereto, at the office or agency of the Company referred to in Paragraph 7(e)
below, provided, however, that any transfer or assignment shall be subject to
the conditions set forth in Paragraph 7(f) hereof and to the applicable
provisions of the Securities Purchase Agreement. Until due presentment for
registration of transfer on the books of the Company, the Company may treat the
registered holder hereof as the owner and holder hereof for all purposes, and
the Company shall not be affected by any notice to the contrary.

            (B)   WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This Warrant

Warrant in connection with any transfer, exchange, or replacement as provided in
this Paragraph 7, this Warrant shall be promptly canceled by the Company. The

Act of 1933, as amended (the "Securities Act") and under applicable state
securities or blue sky laws, the Company may require, as a condition of allowing
such exercise, transfer, or exchange, (i) that the holder or transferee of this

same, represents to the Company that such holder is acquiring this Warrant for
investment and not with a view to the distribution thereof.

EXCLUSIVE JURISDICTION OF THE UNITED STATES FEDERAL COURTS LOCATED IN NEW YORK,
NEW YORK WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS WARRANT, THE AGREEMENTS
ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO
THE MAINTENANCE OF SUCH SUIT OR PROCEEDING. BOTH PARTIES FURTHER AGREE THAT
SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN
EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR
PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER PARTY'S RIGHT TO SERVE PROCESS IN
ANY OTHER MANNER PERMITTED BY LAW. BOTH PARTIES AGREE THAT A FINAL

      10.   MISCELLANEOUS.

            (A)   AMENDMENTS. This Warrant and any provision hereof may only be
amended by an instrument in writing signed by the Company and the holder hereof.

            (B)   DESCRIPTIVE HEADINGS. The descriptive headings of the several
paragraphs of this Warrant are inserted for purposes of reference only, and
shall not affect the meaning or construction of any of the provisions hereof.

            (C)   CASHLESS EXERCISE. Notwithstanding anything to the contrary
contained in this Warrant, if the resale of the Warrant Shares by the holder is
not then registered pursuant to an effective registration statement under the
Securities Act, this Warrant may be exercised by presentation and surrender of
this Warrant to the Company at its principal executive offices with a written
notice of the holder's intention to effect a cashless exercise, including a
calculation of the number of shares of Common Stock to be issued upon such
exercise in accordance with the terms hereof (a "Cashless Exercise"). In the
event of a Cashless Exercise, in lieu of paying the Exercise Price in cash, the
holder shall surrender this Warrant for that number of shares of Common Stock
determined by multiplying the number of Warrant Shares to which it would
otherwise be entitled by a fraction, the numerator of which shall be the
difference between the then current Market Price per share of the Common Stock
and the Exercise Price, and the denominator of which shall be the then current
Market Price per share of Common Stock. For example, if the holder is exercising
100,000 Warrants with a per Warrant exercise price of $0.75 per share through a
cashless exercise when the Common Stock's current Market Price per share is
$2.00 per share, then upon such Cashless Exercise the holder will receive 62,500
shares of Common Stock.

            (D)   REMEDIES. The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the holder, by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations
under this Warrant will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Warrant, that the
holder shall be entitled, in addition to all other available remedies at law or
in equity, and in addition to the penalties assessable herein, to an injunction
or injunctions restraining, preventing or curing any breach of this Warrant and
to enforce specifically the terms and provisions thereof, without the necessity
of showing economic loss and without any bond or other security being required.
