                                WARRANT AGREEMENT

        This WARRANT AGREEMENT (this "Agreement") dated as of June 2, 2005 is
made by and between Vyteris Holdings (Nevada), Inc., a Nevada corporation
("Vyteris," the "Grantor" or the "Company") and Spencer Trask Specialty Group,
LLC, a Delaware limited liability company ("Holder").

        1.      GRANT. This Warrant is being granted in connection with a loan
made pursuant to a certain senior secured promissory note dated June 2, 2005
(the "Note"), with respect to a $750,000 loan made by the Holder to the Company.
Subject to the terms and conditions hereinafter set forth, the Holder is hereby
granted the right to purchase, initially, 9,375 shares of Vyteris common stock
subject to the increase discussed in Section 2 below. In the event that the
number of shares subject to this Warrant is so increased, the Holder shall
surrender its Warrant Certificates (as hereinafter defined) to the Company and
the Company shall reissue to the Holder a new Warrant Certificate reflecting the
increased amount of shares subject to the Warrant and the new Exercise Price (as
defined in Section 5.2 hereof) of the Warrant.

        2.      WARRANT CERTIFICATES. Simultaneously with the signing of this
Agreement, the Company shall issue to the Holder a warrant certificate (the
"Warrant Certificate") evidencing the Holder's right to purchase 9,375 shares of
Vyteris common stock. Unless the Outstanding Balance has been paid in full on or
before July 2, 2005, the Company shall issue to the Holder an additional Warrant
Certificate evidencing the Holder's right to purchase an additional 9,464 shares
of Vyteris Common Stock. Additionally, if the Outstanding Balance has not been
paid in full on or before the Maturity Date (as defined in the Note), the
Company shall issue to the Holder an additional Warrant Certificate evidencing
the Holders right to purchase an additional 64,960 shares of Vyteris Common
Stock. Each Warrant Certificate delivered and to be delivered pursuant to this
Agreement shall be in the form set forth in EXHIBIT A attached hereto and made a
part hereof, with such appropriate insertions, omissions, substitutions, and
other variations as required or permitted by this Agreement.

        3.      EXERCISE OF THE WARRANTS.

        3.1     METHOD OF EXERCISE. The Warrants are initially exercisable for
Warrant Shares at the Exercise Price, subject to adjustment as provided in
Section 7 hereof, payable by certified or official bank check or cash. Upon
surrender of a Warrant Certificate with the annexed Form of Election to Purchase
duly executed, together with payment of the Exercise Price for the Warrant
Shares at the Company's principal offices, currently at 13-01 Pollitt Drive,
Fair Lawn, New Jersey 07410, the registered holder of a Warrant Certificate
("Holder" or "Holders") shall be entitled to receive a certificate or
certificates for the Warrant Shares so purchased. The purchase rights
represented by each Warrant Certificate are exercisable at the option of the
Holder(s) thereof, in whole or in part (but not as to fractional shares of the
Warrant Shares). The Warrants may be exercised to purchase all or part of the
Warrant Shares represented thereby. In the case of purchase of less than all the
Warrant Shares purchasable under any Warrant Certificate, the


                                      -19-
<PAGE>

Company shall cancel such Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the Warrant Shares.

        3.2     NET EXERCISE BY SURRENDER OF THE WARRANTS. In addition to the
method of payment set forth in Section 3.1 and in lieu of any cash payment
required thereunder, the Holder(s) of the Warrants shall have the right at any
time and from time to time to exercise the Warrants in full or in part by
surrendering a Warrant Certificate in the manner specified in Section 3.1 in
exchange for the number of Warrant Shares computed by using the following
formula:

                                    X = Y (A - B)
                                        ---------
                                            A

        Where   X   =   the number of Warrant Shares to be issued to the
                        Holder(s) pursuant to the net exercise.

                Y   =   the number of Warrant Shares subject to the Warrant
                        being exercised or, if only a portion of such Warrant is
                        being exercised, the portion of such Warrant being
                        canceled (at the time of such calculation).

                A   =   the Fair Market Value of one share of Common Stock (at
                        the date of exercise).

                B   =   the Exercise Price (as adjusted to the date of such
                        calculation).

        For purposes of this Section 3.2, the "Fair Market Value" of one share
of Common Stock shall equal: (i) the average of the closing sale price of the
Common Stock (or any other security for which the Warrants are then exercisable)
as quoted on the Nasdaq Stock Market or in the Over-The-Counter Market or the
closing price quoted on any national securities exchange on which such
securities are listed, whichever is applicable, for the five trading days
immediately prior to the date of exercise or, (ii) if no sales take place on any
such trading day, the average of the closing bid and asked prices on such
trading day; or (iii) if the Common Stock (or any other security for which the
Warrants are then exercisable) is not quoted on the Nasdaq Stock Market or
Over-The-Counter or on a national securities exchange, the Fair Market Value of
the Common Stock shall be established in good faith by the disinterested members
of the Company's Board of Directors.

        3.3.    EXERCISE PERIOD. The shall be exercisable, in whole or in part,
during the term commencing on the Warrant Issue Date and ending on the date five
(5) years after the Warrant Issue Date (the "Expiration Time").

        4.      ISSUANCE OF CERTIFICATES.

        4.1     In the event of any exercise of the rights represented by the
Warrants, as promptly as practicable on or after the date of exercise and in any
event within ten (10) business days thereafter, the Company at its expense shall
issue and deliver to the Person or Persons (as


                                       2
<PAGE>

hereinafter defined) entitled to receive the same a certificate or certificates
representing the number of Warrant Shares issued upon such exercise. In the
event that the Warrants are exercised in part, as promptly as practicable on or
after the date of exercise and in any event within ten (10) business days
thereafter, the Company at its sole expense will execute and deliver new
Warrants Certificates of like tenor exercisable for the number of Warrant Shares
for which the Warrants may then be exercised. As used herein, the term "Person"
or "Persons" means any individual or any corporation, partnership, trust,
limited liability company or other entity or organization of any kind.

        4.2     The issuance of the Warrant Shares upon the exercise of the
Warrants, and the delivery of certificates or other instruments representing
such Warrant Shares, shall be made without charge to the Holder(s) for any tax
or other charge of whatever nature in respect of such issuance and the Company
shall bear any such taxes in respect of such issuance.

        5.      EXERCISE PRICE.

        5.1     INITIAL AND ADJUSTED EXERCISE PRICE. Except as otherwise
provided in Section 7 hereof, the Warrants shall be exercisable to purchase
Warrant Shares at an initial price of $4.00 per share; PROVIDED, however, that
if the Outstanding Balance is not repaid on or before August 1, 2005, the
Exercise Price shall be adjusted to $3.58 per share. The adjusted Exercise Price
shall be the price that shall result from time to time from any and all
adjustments of the initial Exercise Price in accordance with the provisions of
Section 7 hereof.

        5.2     EXERCISE PRICE. The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, each as described in
Section 5.1 above, depending upon the context.

        6.      TRANSFER OF SECURITIES

        6.1     LEGENDS. Each Holder, by acceptance of a Warrant Certificate,
covenants and agrees that it is acquiring the Warrants evidenced thereby and the
Warrant Shares for its own account as an investment and not with a view to the
distribution thereof. The Warrants and Warrant Shares have not been registered
under the Securities Act of 1933 (the "Act"), or any state securities laws and
no transfer of any Warrant or Warrant Shares shall be permitted unless the
Company has received notice of such transfer, at the address of its principal
office set forth in Section 3.1 hereof, in the form of assignment attached
hereto, accompanied by an opinion of counsel reasonably satisfactory to the
Company that an exemption from registration of such Warrant or Warrant Shares
under the Act is available for such transfer.

                THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                "ACT"), OR THE SECURITIES LAWS OF ANY STATE. THE SECURITIES MAY
                NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
                STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR
                PURSUANT TO AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
                ISSUER THAT APPLICABLE EXEMPTION FROM THE REGISTRATION
                REQUIREMENTS OF SUCH ACT AND SUCH LAWS IS AVAILABLE.


                                       3
<PAGE>

                THE TRANSFER, EXCHANGE AND EXERCISE OF THE WARRANTS REPRESENTED
                BY THIS CERTIFICATE ARE RESTRICTED IN ACCORDANCE WITH THE
                WARRANT AGREEMENT REFERRED TO HEREIN.

        6.2     REMOVAL OF LEGEND. Upon request of a Holder of a certificate
with the legends required by Section 6.1 hereof, the Company shall issue to such
Holder a new certificate therefor free of any transfer legend, if, with such
request, the Company shall have received an opinion of counsel satisfactory to
the Company in form and substance to the effect that any transfer by such Holder
of the shares evidenced by such certificate will not violate the Act and any
applicable state securities laws. Any purported transfer of any Warrant or
Warrant Shares not in compliance with the provisions of this Section 6 shall be
null and void.

         7. ADJUSTMENT OF EXERCISE PRICE OF THE WARRANT SHARES. The Exercise
Price of the Warrant Shares shall be subject to adjustment from time to time
upon the occurrence of certain events, as follows:

                (a)     ADJUSTMENT FOR RECLASSIFICATION, CONSOLIDATION OR
MERGER. If while any Warrant, or any portion thereof, remains outstanding and
unexpired there shall be (i) a reorganization or recapitalization (other than a
combination, reclassification, exchange or subdivision of shares otherwise
provided for herein), (ii) a merger or consolidation of the Company with or into
another Person in which the Company is not the surviving entity, or a reverse
merger in which the Company is the surviving entity but the shares of the
Company's capital stock outstanding immediately prior to the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash, or otherwise, or (iii) a sale or transfer of the Company's
properties and assets as, or substantially as, an entirety to any other Person
in one transaction or a series of related transactions, then, as a part of such
reorganization, recapitalization, merger, consolidation, sale or transfer,
unless otherwise directed by the Holder(s), all necessary or appropriate lawful
provisions shall be made so that the Holder(s) shall thereafter be entitled to
receive upon exercise of its Warrant, during the period specified herein and
upon payment of the Exercise Price then in effect, the greatest number of shares
of stock or other securities or property that a holder of Warrant Shares
deliverable upon exercise of such Warrant would have been entitled to receive in
such reorganization, recapitalization, consolidation, merger, sale or transfer
if such Warrants had been exercised immediately prior to such reorganization,
recapitalization, merger, consolidation, sale or transfer, all subject to
further adjustment as provided in this Section 7. If the per share consideration
payable to the Holder(s) for Warrant Shares in connection with any such
transaction is in a form other than cash or marketable securities, then the
value of such consideration shall be determined in good faith by the Company's
Board of Directors. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, recapitalizations, consolidations, mergers,
sales and


                                       4
<PAGE>

transfers and to the stock or securities of any other corporation that are at
the time receivable upon the exercise of such Warrant. In all events,
appropriate adjustment shall be made in the application of the provisions of the
Warrants (including adjustment of the Exercise Price and number of Warrant
Shares purchasable pursuant to the terms and conditions of the Warrants) with
respect to the rights and interests of the Holder(s) after the transaction, to
the end that the provisions of each Warrant shall be applicable after that
event, as near as reasonably may be, in relation to any shares or other property
deliverable or issuable after such reorganization, recapitalization, merger,
consolidation, sale or transfer upon exercise of each Warrant.

                (b)     ADJUSTMENTS FOR SPLIT, SUBDIVISION OR COMBINATION OF
WARRANT SHARES. If the Company at any time while the Warrants, or any portion
thereof, remain outstanding and unexpired shall split or subdivide any class of
securities as to which purchase rights under the Warrants exist, into a
different number of securities of the same class, the number of shares of such
class issuable upon exercise of the Warrants immediately prior to such split or
subdivision shall be proportionately adjusted and the Exercise Price for such
class of securities shall be proportionately adjusted. If the Company at any
time while the Warrants, or any portion thereof, remain outstanding and
unexpired shall combine any class of securities as to which purchase rights
under this Agreement exist, into a different number of securities of the same
class, the number of shares of such class issuable upon exercise of The Warrants
immediately prior to such combination shall be proportionately adjusted and the
Exercise Price for such class of securities shall be proportionately adjusted.

                (c)     ADJUSTMENTS FOR DIVIDENDS IN STOCK OR OTHER SECURITIES
OR PROPERTY. If while the Warrants, or any portion thereof, remain outstanding
and unexpired, the Holders shall have received, or, on or after the record date
fixed for the determination of eligible stockholders, shall have become entitled
to receive, without payment therefore, other or additional stock or other
securities or property (other than cash) of the Company by way of dividend, then
and in each case, the Warrants shall represent the right to acquire, in addition
to the number of shares of such class of security receivable upon exercise of
the Warrants, and without payment of any additional consideration therefore, the
amount of such other or additional stock or other securities or property (other
than cash) of the Company that such holder would hold on the date of such
exercise had it been the holder of record of the class of security receivable
upon exercise of the Warrants on the date hereof and had thereafter, during the
period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available by it as aforesaid
during said period, giving effect to all adjustments called for during such
period by the provisions of this Section 7.

                (d)     ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE OF ADDITIONAL
SHARES OF COMMON STOCK. If while the Warrants, or any portion thereof, remain
outstanding and unexpired, the Company shall issue Additional Shares of Common
Stock (as hereinafter defined) without consideration or for a consideration per
share less than the then-applicable Exercise Price, then and in such event, such
Exercise Price shall be reduced, concurrently with such issue, to a price
(rounded up to the nearest cent) determined by multiplying the then-applicable
Exercise Price by a fraction, (i) the numerator of which shall be the number of
shares of the Company's Common Stock issued and outstanding (on an as-converted,
fully-diluted basis) immediately prior to such


                                       5
<PAGE>

issuance plus the quotient obtained by dividing (x) the aggregate consideration
received by the Company for the total number of Additional Shares of Common
Stock so issued by (y) the Exercise Price, and (ii) the denominator of which
shall be the number of shares of the Common Stock issued and outstanding (on a
fully-diluted basis) immediately prior to such issuance plus the number of
Additional Shares of Common Stock so issued.

        For the purposes hereof "Additional Shares of Common Stock" shall mean
all shares of Common Stock, or options, rights, warrants to subscribe for common
stock, or securities convertible into or exchangeable for shares of common
stock, actually issued by the Company on or after the date hereof, other than
shares of common stock issued at any time:

                (i)     upon exercise of the Warrants;

                (ii)    pursuant to the exercise of options, warrants or other
common stock purchase rights issued (or to be issued) to employees, officers or
directors of, or consultants or advisors to, or any strategic ally of, the
Company pursuant to any stock purchase or stock option plan or other arrangement
approved by the Board of Directors;

                (iii)   pursuant to the exercise of options, warrants or any
evidence of indebtedness, shares of capital stock (other than common stock) or
other securities convertible into or exchangeable for the Company's common
stock; or

                (iv)    in connection with the acquisition of all or part of
another entity by stock acquisition, merger, consolidation or other
reorganization, or by the purchase of all or part of the assets of such other
entity (including securities issued to persons formerly employed by such other
entity and subsequently hired by the Company and to any brokers or finders in
connection therewith) where the Company or its stockholders own more than fifty
(50%) percent of the voting power of the acquired, surviving, combined or
successor company.

                (e)     NOTICE OF ADJUSTMENTS. Upon any adjustment of the
Exercise Price and any increase or decrease in the number of Warrant Shares
purchasable upon the exercise of the Warrants, then, and in each such case, the
Company, within 30 days thereafter, shall give written notice thereof to the
Holder(s) at the address of such Holder(s) as shown on the books of the Company
which notice shall state the Exercise Price as adjusted and, if applicable, the
increased or decreased number of Warrant Shares purchasable upon the exercise of
the Warrants, setting forth in reasonable detail the method of calculation of
each.

        8.      REGISTRATION RIGHTS.

                8.1     PIGGYBACK REGISTRATION. If, at any time commencing after
the date hereof until the Expiration Time, the Company proposes to register any
of its securities under the Securities Act of 1933, as amended (the "Act"),
(other than in connection with a merger, pursuant to Form S-8, S-4 or comparable
registration statement) it will give written notice by registered mail, at least
thirty (30) business days prior to the filing of each such registration
statement, to the registered Holder of the Warrant Shares of its intention to do
so. If the Holder


                                       6
<PAGE>

of the Warrant Shares notifies the Company within twenty (20) days after receipt
of any such notice of its desire to include any Warrant Shares in such proposed
registration statement, the Company shall afford the Holder of the Warrant
Shares the opportunity to have any such Warrant Shares registered under such
registration statement.

                        Notwithstanding the provisions of this Section 8.1, (A)
the Company shall have the right any time after it shall have given written
notice pursuant to this Section 8.1 (irrespective of whether a written request
for inclusion of any such securities shall have been made) to elect to postpone
or not to file any such proposed registration statement, or to withdraw the same
after filing but prior to the effective date thereof and (B) if the underwriter
or underwriters, if any, of any such proposed public offering shall be of the
reasonable opinion that the total amount or kind of securities held by the
Holders of Warrant Shares and any other persons or entities entitled to be
included in such public offering would adversely affect the success of such
public offering, then the amount of securities to be offered for the accounts of
Holders of Warrant Shares shall be reduced pro rata to the extent necessary to
reduce the total amount of securities to be included in such public offering to
the amount reasonably recommended by the underwriter or underwriters thereof,
whereupon the Company shall only be obligated to register such limited portion
(which may be none) of the Warrant Shares with respect to which such holder has
provided notice pursuant to this Section 8.1. In no event shall the Company be
required pursuant to this Section 8.1 to reduce the amount of securities to be
registered by it.

                8.2.    COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.
In connection with any registration under the previous paragraph, the Company
covenants and agrees as follows: (i) the Company shall use its best efforts to
file a registration statement as soon as practicable and shall use its best
efforts to have any registration statement declared effective at the earliest
possible time, and shall furnish Holder desiring to sell the Warrant Shares such
number of prospectuses as shall reasonably be requested; (ii) the Company shall
pay all costs (excluding fees and expenses of Holder's counsel and any
underwriting or selling commissions or other charges of any broker-dealer acting
on behalf of such Holder), fees and expenses in connection with all registration
statements filed pursuant to the previous paragraph including, without
limitation, the Company's legal and accounting fees, printing expenses, blue sky
fees and expenses; (iii) the Company shall take all necessary action which may
be required in qualifying or registering the Warrant Shares included in the
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder, provided that the
Company shall not be obligated to execute or file any general consent to service
of process or to qualify as a foreign corporation to do business under the laws
of any such jurisdiction; (iv) the Company shall indemnify the Holder of the
Warrant Shares to be sold pursuant to any registration statement and each
person, if any, who controls such Holder within the meaning of Section 15 of the
Act or


                                       7
<PAGE>

Section 20(a) of the Exchange Act of 1934, as amended (the "Exchange Act"),
against all loss, claim, damage, expense or liability (including all expenses
reasonably incurred in investigating, preparing or defending against any claim
whatsoever) to which any of them may become subject which relate to any
registration statement(s) prepared in connection herewith; (v) the Holder of the
Warrant Shares to be sold pursuant to a registration statement, and their
successors and assigns, shall severally and not jointly indemnify the Company,
its officers and directors and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act, against all loss, claim, damage or expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which they may become subject under the Act, the
Exchange Act or otherwise, arising from any information furnished by or on
behalf of such Holder, or their successors or assigns, for specific inclusion in
such a registration statement; (vi) nothing contained in this Warrant shall be
construed as requiring the Holder to exercise this Warrant prior to the initial
filing of any registration statement or the effectiveness thereof; (vii) the
Company shall prepare and file with the Securities and Exchange Commission (the
"Commission") such amendments, post-effective amendments and supplements to the
registration statement and the prospectus included therein as may be necessary
to keep the registration statement effective until the later of (i) the date
when all Warrant Shares registered have been sold or (ii) until such time as the
Warrant Shares are free of restriction on resale under the Act (by removal of
all restrictive legends, instructions to transfer or otherwise) pursuant to Rule
144; and comply with the provisions of the Act with respect to the disposition
of all securities covered by such registration statement during the applicable
period in accordance with the intended method or methods of distribution by the
sellers thereof as set forth in such registration statement or supplement of the
prospectus; (viii) the Company shall furnish to the Holder participating in an
offering including Warrant Shares and to each underwriter, if any, a signed
counterpart, addressed to the Holder or underwriter, of (A) an opinion of
counsel to the Company, dated the effective date of such registration statement
(and, if such registration includes an underwritten public offering, an opinion
dated the date of the closing under the underwriting agreement), and (B) a "cold
comfort" letter dated the effective date of such registration statement (and, if
such registration includes an underwritten public offering, a letter dated the
date of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities; (vii) the Company shall, as soon as practicable after the effective
date of a registration statement relating to any Warrant Shares pursuant to the
previous paragraph, and in any event within fifteen (15) months thereafter, use
its reasonable efforts to make "generally available to its security holders"
(within the meaning of Rule 158 under the Act) an earnings statement (which need
not be audited) complying with Section 11(a) of the Act and covering a period of
at least (12) consecutive months beginning after the effective date of the
registration statement; and (viii) upon the written request of the Holder, the
Company shall deliver promptly to the Holder participating in an offering
including any Warrant Shares pursuant to the previous paragraph who so requests
and to the managing underwriter, copies of all correspondence between the
Commission and the Company, its counsel or auditors and all memoranda relating
to discussions with the Commission or its staff with respect to the registration
statement and shall permit the Holder and underwriter to do such investigation,
upon reasonable advance notice, with respect to information contained in or
omitted from the registration statement as it deems reasonably necessary to
comply with applicable securities laws or rules of the National Association of
Securities Dealers, Inc. ("NASD"). Such investigation shall include access to
books, records and properties and


                                       8
<PAGE>

opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times
and as often as any such Holder shall reasonably request as it deems necessary
to comply with applicable securities laws and NASD rules.

        9.      EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES. Each Warrant
Certificate is exchangeable without expense, upon the surrender thereof by the
registered Holder(s) at the principal office of the Company, for a new Warrant
Certificate of like form, tenor and date representing in the aggregate the right
to purchase the same number of securities in such denominations as shall be
designated by the Holder(s) thereof at the time of such surrender.

        Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
form and tenor in lieu thereof.

        10.     FRACTIONAL SHARES. No fractional shares will be issued in
connection with any exercise hereunder. Instead, the Company shall pay to
Holder(s) an amount in cash equal to any fractional share to which the Holder(s)
would be entitled, multiplied by the Fair Market Value of the Common Stock.

        11.     STOCK FULLY PAID; RESERVATION OF SHARES. The Company shall at
all times reserve and keep available out of its authorized Common Stock, solely
for the purpose of issuance upon the exercise of the Warrants, such number of
Warrant Shares into which Warrants are exercisable. The Company covenants and
agrees that, upon exercise of the Warrants and payment of the Exercise Price
therefore, all shares of Common Stock shall be duly and validly issued, fully
paid, non-assessable and not subject to the preemptive rights of any
stockholder.

        12.     RIGHTS OF STOCKHOLDERS. Except as expressly provided in Section
3 hereof, no Holder, as such, shall be entitled to vote or receive dividends or

                               WARRANT CERTIFICATE

        This Warrant Certificate certifies that _________________________, or
its registered assigns, is the registered holder of ____________________
warrants (the "Warrants") to purchase initially, at any time after the date
hereof ("Warrant Issue Date") until 5:30 p.m. New York time on ____________ __,

shares of Common Stock, $0.0001 par value per share ("Common Stock") of the
Company, at the initial exercise price, subject to adjustment in certain events
(the "Exercise Price"), of $4.00 upon surrender of this Warrant Certificate and
payment of the Exercise Price at an office or agency of the Company, or by
surrender of this Warrant Certificate in lieu of cash payment, but subject to
the conditions and adjustments set forth in the Warrant Agreement dated as of
May __, 2005, entered into by and among the Company and each holder of Warrants
(the "Warrant Agreement"). Except as otherwise provided in Section 3.2 of the
Warrant Agreement, payment of the Exercise Price shall be made by certified or
official bank check in New York Clearing House funds payable to the order of the
Company.

        No Warrant may be exercised after 5:30 p.m. (New York time) on the
Expiration Date, at which time the Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

        The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and to which reference is hereby made for a description of the
rights, limitations of rights, obligations, duties and immunities thereunder of

        As set forth in Section 7 of in the Warrant Agreement, certain
adjustments may be made to the Exercise Price and the type and/or number of the
Company's securities issuable upon their exercise. In the event of such an
adjustment, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; PROVIDED,
HOWEVER, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter or otherwise impair the rights of the holder
as set forth in the Warrant Agreement.

        Upon due presentment of transfer of this Warrant Certificate and the
executed form of assignment attached hereto at an office or agency of the
Company, a new Warrant Certificate or Warrant Certificates of like form and
tenor and evidencing in the aggregate a like number of Warrants shall be issued
to the transferee(s) in exchange for this Warrant Certificate, subject to the
limitations provided herein and in the Warrant Agreement, without any charge
except for any tax or other governmental charge imposed in connection with such
transfer.

        Upon the exercise of less than all of the Warrants evidenced by this
Warrant Certificate, the Company shall forthwith issue to the holder hereof a
new Warrant Certificate representing such number of unexercised Warrants.

        The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

        All capitalized terms used and not defined in this Warrant Certificate
shall have the meanings ascribed to them in the Warrant Agreement.
