                                WARRANT AGREEMENT

                                     BETWEEN

                            AMERICAN MOLD GUARD, INC.

                                       AND

                         U.S. STOCK TRANSFER CORPORATION

                              DATED AS OF    , 2006

<PAGE>

      This Agreement, dated as of _____________, 2006, is between American Mold
Guard, Inc., a California corporation (the "Company"), and U.S. Stock Transfer
Corporation, a _____________ corporation (the "Warrant Agent").

      The Company, at or about the time that it is entering into this Agreement,
proposes to issue and sell to public investors up to 1,100,000 Units (together
with the additional units issuable as provided herein, the "Units"). Each Unit
consists of two shares of the common stock, no par value, of the Company
("Common Stock), two redeemable Class B warrants (the "Class B Warrants") and
one redeemable Class B warrant (the "Class B Warrants," and together with the
Class B Warrants, the "Warrants"). Each Class B Warrant entitles the holder
thereof to purchase one share of Common Stock at a price equal to $___ [75% of
the initial public offering price of the Units], subject to adjustment under the
terms of the Warrant Agreement. Each Class B Warrant entitles the holder thereof
to purchase one share of Common Stock at a price equal to $___ [100% of the
initial public offering price of the Units], subject to adjustment under the
terms of the Warrant Agreement. Shares of Common Stock issued upon exercise of
the Warrants are referred to herein collectively as the "Warrant Shares." The
Company also proposes to grant to the Representative of the Underwriters of the
public offering an option to purchase 165,000 additional Units to cover
over-allotments, if any.

      The Company also proposes to issue to the Representative of the
Underwriters warrants to purchase up to 110,000 additional Units.

      The Company wishes to retain the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing so to act, in connection with the
issuance, transfer, exchange and replacement of the certificates evidencing the
Warrants to be issued under this Agreement (the "Warrant Certificates") and the
exercise of the Warrants;

      The Company and the Warrant Agent wish to enter into this Agreement to set
forth the terms and conditions of the Warrants and the rights of the holders
thereof ("Warrantholders") and to set forth the respective rights and
obligations of the Company and the Warrant Agent. Each Warrantholder is an
intended beneficiary of this Agreement with respect to the rights of
Warrantholders herein.

      NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein set forth, the parties hereto agree as follows:

SECTION 1. Appointment of Warrant Agent

      The Company appoints the Warrant Agent to act as agent for the Company in
accordance with the instructions in this Agreement and the Warrant Agent accepts
such appointment.

SECTION 2. Date, Denomination and Execution of Warrant Certificates

      The "Warrant Certificates" (and the Form of Election to Purchase and the
Form of Assignment to be printed on the reverse thereof) shall be in registered
form only and shall be substantially of the tenor and purport recited in EXHIBIT
A (with respect to Class A Warrants)

<PAGE>

and EXHIBIT B (with respect to Class B Warrants), and may have such letters,
numbers or other marks of identification or designation and such legends,
summaries or endorsements printed, lithographed or engraved thereon as the
Company may deem appropriate and as are not inconsistent with the provisions of
this Agreement, or as may be required to comply with any law, or with any rule
or regulation made pursuant thereto, or with any rule or regulation of any stock
exchange on which the Common Stock or the Warrants may be listed or any
automated quotation system, or to conform to usage. Each Warrant Certificate
shall entitle the registered holder thereof, subject to the provisions of this
Agreement and of the Class A Warrant Certificate, to purchase, on or after the
date on which the Class A Warrants are first quoted on the Nasdaq Capital Market
("Nasdaq"), and on or before the close of business on the fifth anniversary of
the effective date of the public offering (the "Expiration Date"), one fully
paid and non-assessable share of Common Stock for each Class A Warrant evidenced
by such Class A Warrant Certificate for $____ [75% of the IPO price for the
Unit]. The exercise price of the Warrants (the "Class A Exercise Price") is
subject to adjustment as provided in Section 6 hereof. Each Class B Warrant
Certificate shall entitle the registered holder thereof, subject to the
provisions of this Agreement and of the Class B Warrant Certificate, to
purchase, on or after the date on which the Class B Warrants are first quoted on
Nasdaq, and on or before the close of business on the Expiration Date, one fully
paid and non-assessable share of Common Stock for each Class B Warrant evidenced
by such Class B Warrant Certificate for $___ [100% of the IPO price for the
Unit]. The exercise price of the Class B Warrants (the "Class B Exercise Price")
is subject to adjustment as provided in Section 6 hereof. Each Warrant
Certificate issued as a part of a Unit offered to the public as described in the
recitals, above, shall be dated ___________, 2006; each other Warrant
Certificate shall be dated the date on which the Warrant Agent receives valid
issuance instructions from the Company or a transferring holder of a Warrant
Certificate or, if such instructions specify another date, such other date.

      For purposes of this Agreement, the term "close of business" on any given
date shall mean 5:00 p.m., Eastern time, on such date; provided, however, that
if such date is not a business day, it shall mean 5:00 p.m., Eastern time, on
the next succeeding business day. For purposes of this Agreement, the term
"business day" shall mean any day other than a Saturday, Sunday, or a day on
which banking institutions in New York, New York (or in the state in which the
Warrant Agent maintains the principal office in which it conducts business
related to the Warrants) are authorized or obligated by law to be closed.

      Each Warrant Certificate shall be executed on behalf of the Company by its
Chairperson of the Board of Directors or Vice Chairperson of the Board of
Directors, or its President or a Vice President, and by its Treasurer or an
Assistant Treasurer, or its Secretary or an Assistant Secretary, either manually
or by facsimile signature printed thereon, and have affixed thereto the
Company's seal or a facsimile thereof. Each Warrant Certificate shall be
manually or by facsimile signature printed thereon countersigned by the Warrant
Agent and shall not be valid for any purpose unless so countersigned. In case
any officer of the Company who shall have signed any Warrant Certificate shall
cease to be such officer of the Company before countersignature by the Warrant
Agent and issue and delivery thereof by the Company, such Warrant Certificate,
nevertheless, may be countersigned by the Warrant Agent, issued and delivered
with the same force and effect as though the person who signed such Warrant
Certificate had not ceased to be such officer of the Company.

                                        2

SECTION 3. Subsequent Issue of Warrant Certificates

      Subsequent to their original issuance, no Warrant Certificates shall be
reissued except: (i) Warrant Certificates issued upon transfer thereof in
accordance with Section 4 hereof; (ii) Warrant Certificates issued upon any
combination, split-up or exchange of Warrant Certificates pursuant to Section 4
hereof; (iii) Warrant Certificates issued in replacement of mutilated,
destroyed, lost or stolen Warrant Certificates pursuant to Section 5 hereof;
(iv) Warrant Certificates issued upon the partial exercise of Warrant
Certificates pursuant to Section 7 hereof; and (v) Warrant Certificates issued
to reflect any adjustment or change in the Exercise Price or the number or kind
of shares purchasable thereunder pursuant to Section 22 hereof. The Warrant
Agent is hereby irrevocably authorized to countersign and deliver, in accordance
with the provisions of said Sections 4, 5, 7 and 22, the new Warrant
Certificates required for purposes thereof, and the Company, whenever required
by the Warrant Agent, will supply the Warrant Agent with Warrant Certificates
duly executed on behalf of the Company for such purposes.

SECTION 4. Transfers and Exchanges of Warrant Certificates

      The Warrant Agent will keep or cause to be kept books for registration of
ownership and transfer of the Warrant Certificates issued hereunder. Such
registers shall show the names and addresses of the respective holders of the
Warrant Certificates and the kind and number of Warrants evidenced by each such
Warrant Certificate.

      The Warrant Agent shall, from time to time, register the transfer of any
outstanding Warrants upon the books to be maintained by the Warrant Agent for
that purpose, upon surrender of the Warrant Certificate evidencing such
Warrants, with the Form of Assignment duly filled in and executed with such
signature guaranteed by a financial institution that is a member of a Securities
Transfer Association approved medallion program, such as STAMP, SEMP or MSP, to
the Warrant Agent at its offices located at 1745 Gardena Avenue, 2nd Floor,
Glendale, California 91204, at any time on or before the Expiration Date of such
Warrant, and upon payment to the Warrant Agent for the account of the Company of
an amount equal to any applicable transfer tax. Payment of the amount of such
tax may be made in cash, or by certified or official bank check, payable in
lawful money of the United States of America to the order of the Company.

      Upon receipt of a Warrant Certificate, with the Form of Assignment duly
filled in and executed, accompanied by payment of an amount equal to any
applicable transfer tax, the Warrant Agent shall promptly cancel the surrendered
Warrant Certificate and countersign and deliver to the transferee a new Warrant
Certificate for the number of full Class A Warrants or Class B Warrants, as the
case may be, transferred to such transferee; provided, however, that in case the
registered holder of any Warrant Certificate shall elect to transfer fewer than
all of the Warrants evidenced by such Warrant Certificate, the Warrant Agent in
addition shall promptly countersign and deliver to such registered holder a new
Warrant Certificate or Certificates for the number of full Class A Warrants or
Class B Warrants, as the case may be, not so transferred.

                                        3

<PAGE>

      Any Warrant Certificate or Certificates may be exchanged at the option of
the holder thereof for another Warrant Certificate or Certificates of different
denominations, of like tenor and representing in the aggregate the same kind and
number of Warrants, upon surrender of such Warrant Certificate or Certificates,
with the Form of Assignment duly filled in and executed, to the Warrant Agent,
at any time or from time to time after the close of business on the date hereof
and prior to the close of business on the Expiration Date. The Warrant Agent
shall promptly cancel the surrendered Warrant Certificate and deliver the new
Warrant Certificate pursuant to the provisions of this Section.

SECTION 5. Mutilated, Destroyed, Lost or Stolen Warrant Certificates

      Upon receipt by the Company and the Warrant Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of any
Warrant Certificate, and in the case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and reimbursement to them of all
reasonable expenses incidental thereto, and, in the case of mutilation, upon
surrender and cancellation of the Warrant Certificate, the Warrant Agent shall
countersign and deliver a new Warrant Certificate of like tenor for the same
kind and number of Warrants.

SECTION 6. Adjustments of Number and Kind of Shares Purchasable and Exercise
Price

      The number and kind of securities or other property purchasable upon
exercise of a Warrant shall be subject to adjustment from time to time upon the
occurrence, after the date hereof, of any of the following events:

            A. In case the Company shall (1) pay a dividend in, or make a
distribution of, shares of capital stock on its outstanding Common Stock, (2)
subdivide its outstanding shares of Common Stock into a greater number of such
shares or (3) combine its outstanding shares of Common Stock into a smaller
number of such shares, the total number of shares of Common Stock purchasable
upon the exercise of each Warrant outstanding immediately prior thereto shall be
adjusted so that the holder of any Warrant Certificate thereafter surrendered
for exercise shall be entitled to receive at the same aggregate Exercise Price
the number of shares of capital stock (of one or more classes) which such holder
would have owned or have been entitled to receive immediately following the
happening of any of the events described above had such Warrant been exercised
in full immediately prior to the record date with respect to such event. Any
adjustment made pursuant to this Subsection shall, in the case of a stock
dividend or distribution, become effective as of the record date therefor and,
in the case of a subdivision or combination, be made as of the effective date
thereof. If, as a result of an adjustment made pursuant to this Subsection, the
holder of any Warrant Certificate thereafter surrendered for exercise shall
become entitled to receive shares of two or more classes of capital stock of the
Company, the Board of Directors of the Company (whose determination shall be
conclusive and shall be evidenced by a Board resolution filed with the Warrant
Agent) shall determine the allocation of the adjusted Exercise Price between or
among shares of such classes of capital stock.

            B. In the event of a capital reorganization or a reclassification of
the Common Stock (except as provided in Subsection A. above or Subsection E.
below), any Warrantholder,

                                        4

<PAGE>

upon exercise of Warrants, shall be entitled to receive, in substitution for the
Common Stock to which he would have become entitled upon exercise immediately
prior to such reorganization or reclassification, the shares (of any class or
classes) or other securities or property of the Company (or cash) that he would
have been entitled to receive at the same aggregate Exercise Price upon such
reorganization or reclassification if such Warrants had been exercised
immediately prior to the record date with respect to such event; and in any such
case, appropriate provision (as determined by the Board of Directors of the
Company, whose determination shall be conclusive and shall be evidenced by a
certified Board resolution filed with the Warrant Agent) shall be made for the
application of this Section 6 with respect to the rights and interests
thereafter of the Warrantholders (including but not limited to the allocation of
the Exercise Price between or among shares of classes of capital stock), to the
end that this Section 6 (including the adjustments of the number of shares of
Common Stock or other securities purchasable and the Exercise Price thereof)
shall thereafter be reflected, as nearly as reasonably practicable, in all
subsequent exercises of the Warrants for any shares or securities or other
property (or cash) thereafter deliverable upon the exercise of the Warrants.

            C. Whenever the number of shares of Common Stock or other securities
purchasable upon exercise of a Warrant is adjusted as provided in this Section
6, the Company will promptly file with the Warrant Agent a certificate signed by
of its Chief Executive Officer or its President or a Vice President of the
Company and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary of the Company setting forth the number and kind of
securities or other property purchasable upon exercise of a Warrant, as so
adjusted, stating that such adjustments in the number or kind of shares or other
securities or property conform to the requirements of this Section 6, and
setting forth a brief statement of the facts accounting for such adjustments.
Promptly after receipt of such certificate, the Company, or the Warrant Agent at
the Company's request, will deliver, by first-class, postage prepaid mail, a
brief summary thereof (to be supplied by the Company) to the registered holders
of the outstanding Warrant Certificates; provided, however, that failure to file
or to give any notice required under this Subsection, or any defect therein,
shall not affect the legality or validity of any such adjustments under this
Section 6; and provided, further, that, where appropriate, such notice may be
given in advance and included as part of the notice required to be given
pursuant to Section 12 hereof.

            D. In case of any consolidation of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger
which does not result in any reclassification or change of the outstanding
Common Stock), or in case of any sale or conveyance to another corporation of
the property of the Company as an entirety or substantially as an entirety, the
corporation formed by such consolidation or merger or the corporation which
shall have acquired such assets, as the case may be, shall execute and deliver
to the Warrant Agent a supplemental warrant agreement providing that the holder
of each Warrant then outstanding shall have the right thereafter (until the
expiration of such Warrant) to receive, upon exercise of such Warrant, solely
the kind and amount of shares of stock and other securities and property (or
cash) receivable upon such consolidation, merger, sale or transfer by a holder
of the number of shares of Common Stock of the Company for which such Warrant
might have been exercised immediately prior to such consolidation, merger, sale
or transfer. Such supplemental warrant agreement shall provide for adjustments
which shall be as nearly equivalent as may be

                                        5

<PAGE>

practicable to the adjustments provided in this Section. The above provision of
this Subsection shall similarly apply to successive consolidations, mergers,
sales or transfers.

      The Warrant Agent shall not be under any responsibility to determine the
correctness of any provision contained in any such supplemental warrant
agreement relating to either the kind or amount of shares of stock or securities
or property (or cash) purchasable by holders of Warrant Certificates upon the
exercise of their Warrants after any such consolidation, merger, sale or
transfer or of any adjustment to be made with respect thereto, but subject to
the provisions of Section 20 hereof, may accept as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, a
certificate of a firm of independent certified public accountants (who may be
the accountants regularly employed by the Company) with respect thereto.

            E. Irrespective of any adjustments in the number or kind of shares
issuable upon exercise of Warrants, Warrant Certificates theretofore or
thereafter issued may continue to express the same price and number and kind of
shares as are stated in the similar Warrant Certificates initially issuable
pursuant to this Warrant Agreement.

            F. The Company may retain a firm of independent public accountants
of recognized standing, which may be the firm regularly retained by the Company,
selected by the Audit Committee of the Board of Directors of the Company, and
not disapproved by the Warrant Agent, to make any computation required under
this Section, and a certificate signed by such firm shall, in the absence of
fraud or gross negligence, be conclusive evidence of the correctness of any
computation made under this Section.

            G. For the purpose of this Section, the term "Common Stock" shall
mean: (i) the Common Stock; or (ii) any other class of stock resulting from
successive changes or reclassifications of such Common Stock consisting solely
of changes in par value, or from par value to no par value, or from no par value
to par value. In the event that at any time as a result of an adjustment made
pursuant to this Section, the holder of any Warrant thereafter surrendered for
exercise shall become entitled to receive any shares of capital stock of the
Company other than shares of Common Stock, thereafter the number of such other
shares so receivable upon exercise of any Warrant shall be subject to adjustment
from time to time in a manner and on terms as nearly equivalent as practicable
to the provisions with respect to the Common Stock contained in this Section,
and all other provisions of this Agreement, with respect to the Common Stock,
shall apply on like terms to any such other shares.

            H. The Company may, from time to time and to the extent permitted by
law, reduce the Exercise Price of the Class A Warrants or Class B Warrants by
any amount for a period of not less than 60 days. If the Company so reduces the
Exercise Price of such Warrants, it will give not less than 60 days' notice of
such decrease, which notice may be in the form of a press release, and shall
take such other steps as may be required under applicable law in connection with
any offers or sales of securities at the reduced price.

                                        6

SECTION 7. Exercise and Redemption of Warrants

      Unless the Warrants have been redeemed as provided in this Section 7, the
registered holder of any Warrant Certificate may exercise the Warrants evidenced
thereby, in whole at any time or in part from time to time at or prior to the
close of business, on the Expiration Date relating to such Warrant, subject to
the provisions of Section 9, at which time the Warrant Certificates shall be and
become wholly void and of no value. Warrants may be exercised by their holders
or redeemed by the Company as follows:

            A. Exercise of Warrants shall be accomplished upon surrender of the
Warrant Certificate evidencing such Warrants, with the Form of Election to
Purchase on the reverse side thereof duly filled in and executed, to the Warrant
Agent at its stock transfer office located at 1745 Gardena Avenue, 2nd Floor,
Glendale, California 91204, together with payment to the Company of the Exercise
Price (as of the date of such surrender) of the Warrants then being exercised
and an amount equal to any applicable transfer tax and, if requested by the
Company, any other taxes or governmental charges which the Company may be
required by law to collect in respect of such exercise. Payment of the Exercise
Price and other amounts may be made by wire transfer of good funds, or by
certified or bank cashier's check, payable in lawful money of the United States
of America to the order of the Company. No adjustment shall be made for any cash
dividends, whether paid or declared, on any securities issuable upon exercise of
a Warrant. The Warrant Agent shall deposit or invest any and all funds received
in connection with the exercise of the Warrants in federally insured, interest
bearing accounts with a financial institution or institutions designated by the
Warrant Agent. The Warrant Agent shall have no liability with respect to the
performance of any such investments other than, in the case of funds deposited
in accounts maintained by the Warrant Agent, the liability of the Warrant Agent
to its depositors in such accounts generally. The Company shall be entitled to
the interest, if any, on funds deposited with the Warrant Agent. At the request
of the Company, the Warrant Agent shall remit any funds held by it as a result
of the exercise of the Warrants to the Company.

            B. Upon receipt of a Warrant Certificate, with the Form of Election
to Purchase duly filled in and executed, accompanied by payment of the Exercise
Price of the Warrants being exercised (and of an amount equal to any applicable
taxes or government charges as aforesaid), the Warrant Agent shall promptly
request from the Transfer Agent with respect to the securities to be issued and
deliver to or upon the order of the registered holder of such Warrant
Certificate, in such name or names as such registered holder may designate, a
certificate or certificates for the number of full shares of the securities to
be purchased, together with cash made available by the Company pursuant to
Section 8 hereof in respect of any fraction of a share of such securities
otherwise issuable upon such exercise. If the Warrant is then exercisable to
purchase property other than securities, the Warrant Agent shall take
appropriate steps to cause such property to be delivered to or upon the order of
the registered holder of such Warrant Certificate. In addition, if it is
required by law and upon instruction by the Company, the Warrant Agent will
deliver to each Warrantholder a prospectus which complies with the provisions of
Section 9 of the Securities Act of 1933, as amended, and the Company agrees to
supply Warrant Agent with sufficient number of prospectuses to effectuate that
purpose.

                                        7

<PAGE>

            C. In case the registered holder of any Warrant Certificate shall
exercise fewer than all of the Warrants evidenced by such Warrant Certificate,
the Warrant Agent shall promptly countersign and deliver to the registered
holder of such Warrant Certificate, or to his duly authorized assigns, a new
Warrant Certificate or Certificates evidencing the number of Warrants that were
not so exercised.

            D. Each person in whose name any certificate for securities is
issued upon the exercise of Warrants shall for all purposes be deemed to have
become the holder of record of the securities represented thereby as of, and
such certificate shall be dated, the date upon which the Warrant Certificate was
duly surrendered in proper form and payment of the Exercise Price (and of any
applicable taxes or other governmental charges) was made; provided, however,
that if the date of such surrender and payment is a date on which the stock
transfer books of the Company are closed, such person shall be deemed to have
become the record holder of such shares as of, and the certificate for such
shares shall be dated, the next succeeding business day on which the stock
transfer books of the Company are open (whether before, on or after the
Expiration Date relating to such Warrant) and the Warrant Agent shall be under
no duty to deliver the certificate for such shares until such date. The Company
covenants and agrees that it shall not cause its stock transfer books to be
closed for a period of more than 20 consecutive business days except upon
consolidation, merger, sale of all or substantially all of its assets,
dissolution or liquidation or as otherwise provided by law.

            E. The Class B Warrants outstanding at the time of redemption may be
redeemed at the option of the Company, beginning on ___________, 2006 [six
months from the date of this Agreement], in whole or in part on a pro-rata
basis, by giving not less than 30 days' prior notice as provided in Section 7(F)
below, which notice may not be give before, but may be given at any time after,
the closing price of the Common Stock on the principal market, exchange or
quotation system, on which it is then traded or quoted has equaled or exceeded
$____ [100% of the initial unit offering price] per share on each of five
consecutive trading days that occur subsequent to the date of this Warrant
Agreement. The price at which Class B Warrants may be redeemed (the "Redemption
Price") is $0.25 per Class B Warrant (subject to adjustment in the event of a
stock split, dividend or the like). On and after the redemption date the holders
of record of redeemed Class B Warrants shall be entitled to payment of the
Redemption Price upon surrender of such redeemed Class B Warrants to the Company
at the office of the Warrant Agent designated for that purpose. Class B Warrants
are non-redeemable.

            F. The Class B Warrants outstanding at the time of redemption may be
redeemed at the option of the Company, beginning on ___________, 2006 [six
months from the date of this Agreement], in whole or in part on a pro-rata
basis, by giving not less than 30 days' prior notice as provided in Section 7(F)
below, which notice may not be give before, but may be given at any time after,
the Company's gross revenue for any 12-month period preceding the date of the
notice, as confirmed by an independent audit, equals or exceeds $20 million. The
price at which Class B Warrants may be redeemed (the "Redemption Price") is
$0.25 per Class B Warrant (subject to adjustment in the event of a stock split,
dividend or the like). On and after the redemption date the holders of record of
redeemed Class B Warrants shall be entitled to payment of the Redemption Price
upon surrender of such redeemed Class B Warrants to the Company at the office of
the Warrant Agent designated for that purpose.

                                        8

<PAGE>

            G. Notice of redemption of the Class A Warrants or Class B Warrants,
as the case may be, shall be given at least 30 days prior to the redemption date
by first class mail, postage prepaid, a copy of such notice to the Warrant Agent
and to all of the holders of record of Class A Warrants or the Class B Warrants,
as the case may be, at their respective addresses appearing on the books or
transfer records of the Company or such other address designated in writing by
the holder of record to the Warrant Agent not less than 40 days prior to the
redemption date.

            H. From and after the redemption date, all rights of the Class A
Warrantholders or the Class B Warrantholders, as the case may be (except the
right to receive the Redemption Price) shall terminate, but only if: (a) no
later than one day prior to the redemption date the Company shall have
irrevocably deposited with the Warrant Agent as paying agent a sufficient amount
to pay on the redemption date the Redemption Price for all Class A Warrants or
the Class B Warrants, as the case may be, called for redemption; and (b) the
notice of redemption shall have stated the name and address of the Warrant Agent
and the intention of the Company to deposit such amount with the Warrant Agent
no later than one day prior to the redemption date.

            I. On the redemption date, the Warrant Agent shall pay to the
holders of record of redeemed Class A Warrants or the Class B Warrants, as the
case may be, all monies received by the Warrant Agent for the redemption of
Class A Warrants or the Class B Warrants, as the case may be, to which the
holders of record of such redeemed Class A Warrants or the Class B Warrants, as
the case may be, who shall have surrendered their Class A Warrants or their
Class B Warrants, as the case may be, are entitled. The Warrant Agent shall have
no obligation to pay for the redemption of the Class A Warrants or the Class B
Warrants, as the case may be, except to the extent that funds for such payment
have been provided to it by the Company.

            J. Any amounts deposited with the Warrant Agent that are not
required for redemption of Class A Warrants or the Class B Warrants, as the case
may be, may be withdrawn by the Company. Any amounts deposited with the Warrant
Agent that shall be unclaimed after six months after the redemption date shall
be redelivered back to the Company, and thereafter the holders of the Class A
Warrants or the Class B Warrants, as the case may be, called for redemption for
which such funds were deposited shall look solely to the Company for payment.
The Company shall be entitled to the interest, if any, on funds deposited with
the Warrant Agent and the holders of redeemed Class A Warrants or the Class B
Warrants, as the case may be, shall have no right to any such interest. The
Warrant Agent shall deposit or invest any and all funds deposited with it by the
Company in connection with any redemption in federally insured, interest bearing
accounts with a financial institution or institutions designated by the Warrant
Agent but shall have no liability with respect to the performance of any such
investments other than, in the case of funds deposited in accounts maintained by
the Warrant Agent, the liability of the Warrant Agent to its depositors in such
accounts, generally.

            K. If the Company fails to make a sufficient deposit with the
Warrant Agent as provided above, the holder of any Class A Warrants or the Class
B Warrants, as the case may be, called for redemption may at the option of the
holder (a) by notice to the Company declare the notice of redemption a nullity
as to such holder, or (b) maintain an action against the Company for the
Redemption Price. If the holder brings such an action, the Company will pay
reasonable

attorneys' fees of the holder. If the holder fails to bring an action against
the Company for the Redemption Price within 60 days after the redemption date,
the holder shall be deemed to have elected to declare the notice of redemption
to be a nullity as to such holder and such notice shall be without any force or
effect as to such holder. Except as otherwise specifically provided in this
Paragraph K, a notice of redemption, once mailed by the Company as provided in
Paragraph G, shall be irrevocable.

SECTION 8. Fractional Interests

      The Company shall not issue any Warrant Certificate evidencing a fraction
of a Warrant, nor shall the Company issue any fractional share of securities
upon exercise of a Warrant. By accepting a Warrant Certificate, the holder
thereof expressly waives any right to receive a Warrant Certificate evidencing
any fraction of a Warrant or to receive any fractional share of securities upon
exercise of a Warrant. In lieu of fractional interest in a Warrant or a share of
Common Stock created upon separation of the Units or exercise of a Warrant,
respectively, a holder shall receive an amount of cash equal to the fraction
times the closing price of the Warrants on the date of separation of the Units
(if the fractional interest is in a Warrant) or the closing price of the Common
Stock (if the fractional interest is in Common Stock) on Nasdaq or such other
exchange, market or quotation service on which the Common Stock or warrant, as
the case may be, principally trades or is quoted.

SECTION 9. Reservation of Equity Securities

      The Company covenants that it will at all times reserve and keep
available, free from any pre-emptive rights, out of its authorized and unissued
equity securities, solely for the purpose of issue upon exercise of the
Warrants, such number of shares of equity securities of the Company as shall
then be issuable upon the exercise of all outstanding Warrants ("Equity
Securities"). The Company covenants that all Equity Securities which shall be so
issuable shall, upon such issue, be duly authorized, validly issued, fully paid
and non-assessable.

      The Company covenants that if any equity securities, required to be
reserved for the purpose of issue upon exercise of the Warrants hereunder,
require registration with or approval of any governmental authority under any
federal or state law before such shares may be issued upon exercise of Warrants,
the Company will use all commercially reasonable efforts to cause such
securities to be duly registered, or approved, as the case may be, and, to the
extent practicable, take all such action in anticipation of and prior to the
exercise of the Warrants, including, without limitation, filing any and all
post-effective amendments to the Company's Registration Statement on Form SB-2
(Registration No. 333-_______) necessary to permit a public offering of the
securities underlying the Warrants at any and all times during the term of this
Agreement, provided, however, that in no event shall such securities be issued,
and the Company is authorized to refuse to honor the exercise of any Warrant, if
such exercise would result in the opinion of the Company's Board of Directors,
upon advice of counsel, in the violation of any law; and provided further that,
in the case of a Warrant exercisable solely for securities listed on a
securities exchange or for which there are at least two independent market
makers, in lieu of obtaining such registration or approval, the Company may
elect to redeem Warrants submitted to the Warrant Agent for exercise for a price
equal to the difference between

                                       10

<PAGE>

the aggregate low asked price, or closing price, as the case may be, of the
securities for which such Warrant is exercisable on the date of such submission
and the Exercise Price of such Warrants; in the event of such redemption, the
Company will pay to the holder of such Warrants the above-described redemption
price in cash within 10 business days after receipt of notice from the Warrant
Agent that such Warrants have been submitted for exercise.

SECTION 10. Reduction of Exercise Price Below Par Value

      Before taking any action that would cause an adjustment pursuant to
Section 6 hereof reducing the portion of the Class B Exercise Price or the Class
B Exercise Price required to purchase one share of capital stock below the then
par value (if any) of a share of such capital stock, the Company will use its
best efforts to take any corporate action which, in the opinion of its counsel,
may be necessary in order that the Company may validly and legally issue fully
paid and non-assessable shares of such capital stock.

SECTION 11. Payment of Taxes

      The Company covenants and agrees that it will pay when due and payable any
and all federal and state documentary, stamp and other original issue taxes
which may be payable in respect of the original issuance of the Warrant
Certificates, or any shares of Common Stock or other securities upon the
exercise of Warrants. The Company shall not, however, be required (i) to pay any
tax which may be payable in respect of any transfer involved in the transfer and
delivery of Warrant Certificates or the issuance or delivery of certificates for
Common Stock or other securities in a name other than that of the registered
holder of the Warrant Certificate surrendered for purchase or (ii) to issue or
deliver any certificate for shares of Common Stock or other securities upon the
exercise of any Warrant Certificate until any such tax shall have been paid, all
such tax being payable by the holder of such Warrant Certificate at the time of
surrender.

SECTION 12. Notice of Certain Corporate Action

      In case the Company after the date hereof shall propose (i) to offer to
the holders of Common Stock, generally, rights to subscribe to or purchase any
additional shares of any class of its capital stock, any evidences of its
indebtedness or assets, or any other rights or options or (ii) to effect any
reclassification of Common Stock (other than a reclassification involving merely
the subdivision or combination of outstanding shares of Common Stock) or any
capital reorganization, or any consolidation or merger to which the Company is a
party and for which approval of any stockholders of the Company is required, or
any sale, transfer or other disposition of its property and assets substantially
as an entirety, or the liquidation, voluntary or involuntary dissolution or
winding-up of the Company, then, in each such case, the Company shall file with
the Warrant Agent and the Company, or the Warrant Agent on the Company's behalf
and at the Company's request, shall mail (by first-class, postage prepaid mail)
to all registered holders of the Warrant Certificates notice of such proposed
action, which notice shall specify the date on which the books of the Company
shall close or a record be taken for such offer of rights or options, or the
date on which such reclassification, reorganization, consolidation, merger,
sale, transfer, other disposition, liquidation, voluntary or involuntary

                                       11

<PAGE>

dissolution or winding-up shall take place or commence, as the case may be, and
which shall also specify any record date for determination of holders of Common
Stock entitled to vote thereon or participate therein and shall set forth such
facts with respect thereto as shall be reasonably necessary to indicate any
adjustments in the Class B Exercise Price or the Class B Exercise Price and the
number or kind of shares or other securities purchasable upon exercise of
Warrants which will be required as a result of such action. Such notice shall be
filed and mailed in the case of any action covered by clause (i) above, at least
ten days prior to the record date for determining holders of the Common Stock
for purposes of such action or, if a record is not to be taken, the date as of
which the holders of shares of Common Stock of record are to be entitled to such
offering; and, in the case of any action covered by clause (ii) above, at least
20 days prior to the earlier of the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, other disposition,
liquidation, voluntary or involuntary dissolution or winding-up is expected to
become effective and the date on which it is expected that holders of shares of
Common Stock of record on such date shall be entitled to exchange their shares
for securities or other property deliverable upon such reclassification,
reorganization, consolidation, merger, sale, transfer, other disposition,
liquidation, voluntary or involuntary dissolution or winding-up.

      Failure to give any such notice or any defect therein shall not affect the
legality or validity of any transaction listed in this Section 12.

SECTION 13. Disposition of Proceeds on Exercise of Warrant Certificates, etc.

      The Warrant Agent shall account promptly to the Company with respect to
Warrants exercised and concurrently pay to the Company all monies received by
the Warrant Agent for the purchase of securities or other property through the
exercise of such Warrants.

      The Warrant Agent shall keep copies of this Agreement available for
inspection by Warrantholders during normal business hours at its stock transfer
office. Copies of this Agreement may be obtained upon written request addressed
to the Warrant Agent at its stock transfer office located at 1745 Gardena
Avenue, 2nd Floor, Glendale, California 91204.

SECTION 14. Warrantholder Not Deemed a Stockholder

      No Warrantholder, as such, shall be entitled to vote, receive dividends or
be deemed the holder of Common Stock or any other securities of the Company
which may at any time be issuable on the exercise of the Warrants represented
thereby for any purpose whatever, nor shall anything contained herein or in any
Warrant Certificate be construed to confer upon any Warrantholder, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issuance of stock, reclassification of stock, change
of par value or change of stock to no par value, consolidation, merger,
conveyance or otherwise), or to receive notice of meetings or other actions
affecting stockholders (except as provided in Section 12 hereof), or to receive
dividend or subscription rights, or otherwise, until such Warrant Certificate
shall have been exercised in accordance with the provisions hereof and the
receipt of the Exercise Price and any other amounts payable upon such exercise
by the Warrant Agent.

                                       12

<PAGE>

SECTION 15. Right of Action

      All rights of action in respect to this Agreement are vested in the
respective registered holders of the Warrant Certificates; and any registered
holder of any Warrant Certificate, without the consent of the Warrant Agent or
of any other holder of a Warrant Certificate, may, in his own behalf for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company suitable to enforce, or otherwise in respect of, his right
to exercise the Warrants evidenced by such Warrant Certificate, for the purchase
of shares of the Common Stock in the manner provided in the Warrant Certificate
and in this Agreement.

SECTION 16. Agreement of Holders of Warrant Certificates

      Every holder of a Warrant Certificate by accepting the same consents and
agrees with the Company, the Warrant Agent and with every other holder of a
Warrant Certificate that:

            A. the Warrant Certificates are transferable on the registry books
of the Warrant Agent only upon the terms and conditions set forth in this
Agreement; and

            B. the Company and the Warrant Agent may deem and treat the person
in whose name the Warrant Certificate is registered as the absolute owner of the
Warrant (notwithstanding any notation of ownership or other writing thereon made
by anyone other than the Company or the Warrant Agent) for all purposes whatever
and neither the Company nor the Warrant Agent shall be affected by any notice to
the contrary.

SECTION 17. Cancellation of Warrant Certificates

      In the event that the Company shall purchase or otherwise acquire any
Warrant Certificate or Certificates after the issuance thereof, such Warrant
Certificate or Certificates shall thereupon be delivered to the Warrant Agent
and be canceled by it and retired. The Warrant Agent shall also cancel any
Warrant Certificate delivered to it for exercise, in whole or in part, or
delivered to it for transfer, split-up, combination or exchange. Warrant
Certificates so canceled shall be retained by the Warrant Agent or disposed of
in accordance with its customary business practices relating to such matters;
provided that the Warrant Agent shall give the Company notice prior to its
disposition or destruction of the Warrant Certificates.

SECTION 18. Concerning the Warrant Agent

      The Company agrees to pay to the Warrant Agent from time to time, upon
receipt of a written demand of the Warrant Agent, reasonable compensation for
all services rendered by it hereunder and also its reasonable expenses,
including counsel fees, and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Warrant Agent agrees to use its best efforts to submit in advance
a written estimate of any costs in excess of $2,500 that it expects to incur in
the exercise and performance of its duties hereunder. The Company also agrees to
indemnify the Warrant Agent for, and to hold it harmless against, any loss,
liability or expense, incurred without gross

                                       13

<PAGE>

negligence, bad faith or willful misconduct on the part of the Warrant Agent,
arising out of or in connection with the acceptance and administration of this
Agreement.

SECTION 19. Merger or Consolidation or Change of Name of Warrant Agent

      Any corporation into which the Warrant Agent may be merged or with which
it may be consolidated, or any corporation resulting from any merger or
consolidation to which the Warrant Agent shall be a party, or any corporation
succeeding to the corporate trust business of the Warrant Agent, shall be the
successor to the Warrant Agent hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto, provided that
such corporation would be eligible for appointment as a successor warrant agent
under the provisions of Section 21 hereof. In case at the time such successor to
the Warrant Agent shall succeed to the agency created by this Agreement, any of
the Warrant Certificates shall have been countersigned but not delivered, any
such successor to the Warrant Agent may adopt the countersignature of the
original Warrant Agent and deliver such Warrant Certificates so countersigned;
and in case at that time any of the Warrant Certificates shall not have been
countersigned, any successor to the Warrant Agent may countersign such Warrant
Certificates either in the name of the predecessor Warrant Agent or in the name
of the successor Warrant Agent; and in all such cases such Warrant Certificates
shall have the full force provided in the Warrant Certificates and in this
Agreement.

      In case at any time the name of the Warrant Agent shall be changed and at
such time any of the Warrant Certificates shall have been countersigned but not
delivered, the Warrant Agent may adopt the countersignature under its prior name
and deliver Warrant Certificates so countersigned; and in case at that time any
of the Warrant Certificates shall not have been countersigned, the Warrant Agent
may countersign such Warrant Certificates either in its prior name or in its
changed name; and in all such cases such Warrant Certificates shall have the
full force provided in the Warrant Certificates and in this Agreement.

SECTION 20. Duties of Warrant Agent

      The Warrant Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which the Company
and the holders of Warrant Certificates, by their acceptance thereof, shall be
bound:

            A. The Warrant Agent may consult with counsel satisfactory to it
(who may be counsel for the Company), and the opinion of such counsel shall be
full and complete authorization and protection to the Warrant Agent as to any
action taken, suffered or omitted by it in good faith and in accordance with
such opinion; provided, however, that the Warrant Agent shall have exercised
reasonable care in the selection of such counsel. Fees and expenses of such
counsel, to the extent reasonable, shall be paid by the Company, and subject to
the provisions of Section 18 hereof.

            B. Whenever in the performance of its duties under this Agreement,
the Warrant Agent shall deem it necessary or desirable that any fact or matter
be proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other

                                       14

<PAGE>

evidence in respect thereof be herein specifically prescribed) may be deemed to
be conclusively proved and established by a certificate signed by a Chairperson
or co-Chairperson of the Board or the President or a Vice President or the
Secretary of the Company and delivered to the Warrant Agent; and such
certificate shall be full authorization to the Warrant Agent for any action
taken or suffered in good faith by it under the provisions of this Agreement in
reliance upon such certificate.

            C. The Warrant Agent shall be liable hereunder only for its own
gross negligence, bad faith or willful misconduct.

            D. The Warrant Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained in this Agreement or in the Warrant
Certificates (except its countersignature on the Warrant Certificates and such
statements or recitals as describe the Warrant Agent or action taken or to be
taken by it) or be required to verify the same, but all such statements and
recitals are and shall be deemed to have been made by the Company only.

            E. The Warrant Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Warrant Agent) or in respect of the
validity or execution of any Warrant Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Warrant Certificate;
nor shall it be responsible for the making of any change in the number of shares
of Common Stock for which a Warrant is exercisable required under the provisions
of Section 6 or responsible for the manner, method or amount of any such change
or the ascertaining of the existence of facts that would require any such
adjustment or change (except with respect to the exercise of Warrant
Certificates after actual notice of any adjustment of the Exercise Price); nor
shall it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any shares of Common Stock to be
issued pursuant to this Agreement or any Warrant Certificate or as to whether
any shares of Common Stock will, when issued, be validly issued, fully paid and
non-assessable.

            F. The Warrant Agent shall be under no obligation to institute any
action, suit or legal proceeding or take any other action likely to involve
expense unless the Company or one or more registered holders of Warrant
Certificates shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred. All rights of action
under this Agreement or under any of the Warrants may be enforced by the Warrant
Agent without the possession of any of the Warrants or the production thereof at
any trial or other proceeding relative thereto, and any such action, suit or
proceeding instituted by the Warrant Agent shall be brought in its name as
Warrant Agent, and any recovery of judgment shall be for the ratable benefit of
the registered holders of the Warrant Certificates, as their respective rights
or interests may appear.

            G. The Warrant Agent and any shareholder, director, officer or
employee of the Warrant Agent may buy, sell or deal in any of the Warrants or
other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend
money to or otherwise act as fully and freely as though it were not Warrant

                                       15

<PAGE>

Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity.

            H. The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from a
Chairman or co-Chairman of the Board or President or a Vice President or the
Secretary or the Controller of the Company, and to apply to such officers for
advice or instructions in connection with the Warrant Agent's duties, and it
shall not be liable for any action taken or suffered or omitted by it in good
faith in accordance with instructions of any such officer.

            I. The Warrant Agent will not be responsible for any failure of the
Company to comply with any of the covenants contained in this Agreement or in
the Warrant Certificates to be complied with by the Company.

            J. The Warrant Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys, agents or employees and the Warrant Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys, agents or employees or for any loss to the Company resulting
from such neglect or misconduct; provided, however, that reasonable care shall
have been exercised in the selection and continued employment of such attorneys,
agents and employees.

            K. The Warrant Agent will not incur any liability or responsibility
to the Company or to any holder of any Warrant Certificate for any action taken,
or any failure to take action, in reliance on any notice, resolution, waiver,
consent, order, certificate, or other paper, document or instrument reasonably
believed by the Warrant Agent to be genuine and to have been signed, sent or
presented by the proper party or parties.

            L. The Warrant Agent will act hereunder solely as agent of the
Company in a ministerial capacity, and its duties will be determined solely by
the provisions hereof. The Warrant Agent will not be liable for anything which
it may do or refrain from doing in connection with this Agreement except for its
own gross negligence, bad faith or willful conduct.

SECTION 21. Change of Warrant Agent

      The Warrant Agent may resign and be discharged from its duties under this
Agreement upon 30 days' prior notice in writing mailed, by registered or
certified mail, to the Company. The Company may remove the Warrant Agent or any
successor warrant agent upon 30 days' prior notice in writing, mailed to the
Warrant Agent or successor warrant agent, as the case may be, by registered or
certified mail. If the Warrant Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Warrant Agent and shall, within 15 days following such appointment, give
notice thereof in writing to each registered holder of the Warrant Certificates.
If the Company shall fail to make such appointment within a period of 15 days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Warrant Agent,
then the Company agrees to perform the duties of the Warrant Agent hereunder
until a

                                       16

<PAGE>

successor Warrant Agent is appointed. After appointment and execution of a copy
of this Agreement in effect at that time, the successor Warrant Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Warrant Agent without further act or deed; but the
former Warrant Agent shall deliver and transfer to the successor Warrant Agent,
within a reasonable time, any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose. Failure to give any notice provided for in this Section, however,
or any defect therein shall not affect the legality or validity of the
resignation or removal of the Warrant Agent or the appointment of the successor
warrant agent, as the case may be.

SECTION 22. Issuance of New Warrant Certificates

      Notwithstanding any of the provisions of this Agreement or the several
Warrant Certificates to the contrary, the Company may, at its option, issue new
Warrant Certificates in such form as may be approved by its Board of Directors
to reflect any adjustment or change in the Class B Exercise Price or the Class B
Exercise Price or the number or kind of shares purchasable under the several
Warrant Certificates made in accordance with the provisions of this Agreement.

SECTION 23. Notices

      Notice or demand pursuant to this Agreement to be given or made on the

SECTION 24. Modification of Agreement

      The Warrant Agent may, without the consent or concurrence of the
Warrantholders, by supplemental agreement or otherwise, concur with the Company
in making any changes or corrections in this Agreement that the Warrant Agent
shall have been advised by counsel (who may be counsel for the Company) are
necessary or desirable to cure any ambiguity or to correct any defective or
inconsistent provision or clerical omission or mistake or manifest error herein
contained, or to make any other provisions in regard to matters or questions
arising hereunder and which shall not be inconsistent with the provisions of the
Warrant Certificates and which shall not adversely affect the interests of the
Warrantholders. As of the date hereof, this Agreement contains the entire and
only agreement, understanding, representation, condition, warranty or covenant
between the parties hereto with respect to the matters herein, supersedes any
and all other agreements between the parties hereto relating to such matters,
and may be modified or amended only by a written agreement signed by both
parties hereto pursuant to the authority granted by the first sentence of this
Section.

SECTION 25. Successors

      All the covenants and provisions of this Agreement by or for the benefit
of the Company or the Warrant Agent shall bind and inure to the benefit of their
respective successors and assigns hereunder.

SECTION 26. California Contract

deemed to be a contract made under the laws of the State of California and for
all purposes shall be construed in accordance with the laws of said State.

Expiration Date, or such earlier date upon which all Warrants shall have been
exercised or redeemed, except that the Warrant Agent shall account to the
Company as to all Warrants outstanding and all cash held by it as of the close
of business on the Expiration Date.

SECTION 28. Benefits of this Agreement

      Nothing in this Agreement or in the Warrant Certificates shall be
construed to give to any person or corporation other than the Company, the
Warrant Agent, and their respective successors and assigns hereunder and the
registered holders of the Warrant Certificates any legal or equitable right,
remedy or claim under this Agreement; but this Agreement shall be for the sole
and exclusive benefit of the Company, the Warrant Agent, their respective
successors and assigns hereunder and the registered holders of the Warrant
Certificates.

Second Floor, Glendale, California 91204 of U.S. Stock Transfer Corporation,
Warrant Agent of the Company ("Warrant Agent") or of its successor warrant agent
or, if there be no successor warrant agent, at the corporate offices of the
Company, and upon payment of the Exercise Price (as defined in the Warrant
Agreement) and any applicable taxes paid either in cash, or by certified or
official bank check, payable in lawful money of the United States of America to
the order of the Company. Each Class A Warrant initially entitles the holder to

or other property for which the Class A Warrants are exercisable are subject to
adjustment in certain events, such as mergers, splits, stock dividends, reverse

the Common Stock on the principal market, exchange or quotation service on which
it is traded or quoted has equaled or exceeded $___ per share on each of five
consecutive trading days. The Redemption

                                    Exhibit A

<PAGE>

dividend or the like). All Warrants not theretofore exercised will expire on the
Expiration Date.

      This Warrant Certificate is subject to all of the terms, provisions and
conditions of the Warrant Agreement, dated as of ___________, 2006, between the
Company and the Warrant Agent, to all of which terms, provisions and conditions
the registered holder of this Warrant Certificate consents by acceptance hereof.
The Warrant Agreement is incorporated herein by reference and made a part hereof
and reference is made to the Warrant Agreement for a full description of the
rights, limitations of rights, obligations, duties and immunities of the Warrant
Agent, the Company and the holders of the Warrant Certificates. Copies of the
Warrant Agreement are available for inspection at the stock transfer office of
the Warrant Agent or may be obtained upon written request addressed to the
Company at American Mold Guard, Inc., 30200 Rancho Viejo Road, Suite G, San
Juan Capistrano, CA 92675, Attention: Chief Financial Officer.

      The Company shall not be required upon the exercise of the Class A
Warrants evidenced by this Warrant Certificate to issue fractions of Class A
Warrants, Common Stock or other securities, but shall make adjustment therefor
in cash on the basis of the current market value of any fractional interest as
provided in the Warrant Agreement.

      In certain cases, the sale of securities by the Company upon exercise of
Class A Warrants may violate the securities laws of the United States, certain
states thereof or other jurisdictions. The Company has agreed to use all
commercially reasonable efforts to cause a registration statement to continue to
be effective during the term of the Class A Warrants with respect to such sales
under the Securities Act of 1933, and to take such action under the laws of
various states as may be required to cause the sale of securities upon exercise
to be lawful. However, the Company will not be required to honor the exercise of
Class A Warrants if, in the opinion of the Board of Directors, upon advice of
counsel, the sale of securities upon such exercise would be unlawful. In certain
cases, the Company may, but is not required to, purchase Class A Warrants
submitted for exercise for a cash price equal to the difference between the
market price of the securities obtainable upon such exercise and the exercise
price of such Class A Warrants.

      This Warrant Certificate, with or without other Certificates, upon
surrender to the Warrant Agent, any successor warrant agent or, in the absence
of any successor warrant agent, at the corporate offices of the Company, may be
exchanged for another Warrant Certificate or Certificates evidencing in the
aggregate the same number of Class A Warrants as the Warrant Certificate or
Certificates so surrendered. If the Class A Warrants evidenced by this Warrant
Certificate shall be exercised in part, the holder hereof shall be entitled to
receive upon surrender hereof another Warrant Certificate or Certificates
evidencing the number of Class A Warrants not so exercised.

      No holder of this Warrant Certificate, as such, shall be entitled to vote,
receive dividends or be deemed the holder of Common Stock or any other
securities of the Company which may at any time be issuable on the exercise
hereof for any purpose whatsoever, nor shall anything contained in the Warrant
Agreement or herein be construed to confer upon the holder of this Warrant
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting

                                    Exhibit A

<PAGE>

thereof or give or withhold consent to any corporate action (whether upon any
matter submitted to stockholders at any meeting thereof, or give or withhold
consent to any merger, recapitalization, issuance of stock, reclassification of
stock, change of par value or change of stock to no par value, consolidation,
conveyance or otherwise) or to receive notice of meetings or other actions
affecting stockholders (except as provided in the Warrant Agreement) or to
receive dividends or subscription rights or otherwise until the Class A Warrants
evidenced by this Warrant Certificate shall have been exercised and the Common
Stock purchasable upon the exercise thereof shall have become deliverable as
provided in the Warrant Agreement.

      If this Warrant Certificate shall be surrendered for exercise within any
period during which the transfer books for the Company's Common Stock or other
class of stock purchasable upon the exercise of the Class A Warrants evidenced
by this Warrant Certificate are closed for any purpose, the Company shall not be
required to make delivery of certificates for shares purchasable upon such
transfer until the date of the reopening of said transfer books.

      Every holder of this Warrant Certificate by accepting the same consents
and agrees with the Company, the Warrant Agent, and with every other holder of a
Warrant Certificate that:

      (a) this Warrant Certificate is transferable on the registry books of the
Warrant Agent only upon the terms and conditions set forth in the Warrant
Agreement, and

      (b) the Company and the Warrant Agent may deem and treat the person in
whose name this Warrant Certificate is registered as the absolute owner hereof
(notwithstanding any notation of ownership or other writing thereon made by
anyone other than the Company or the Warrant Agent) for all purposes whatsoever
and neither the Company nor the Warrant Agent shall be affected by any notice to
the contrary. The Company shall not be required to issue or deliver any
certificate for shares of Common Stock or other securities upon the exercise of
Class A Warrants evidenced by this Warrant Certificate until any tax which may
be payable in respect thereof by the holder of this Warrant Certificate pursuant
to the Warrant Agreement shall have been paid, such tax being payable by the
holder of this Warrant Certificate at the time of surrender.

      This Warrant Certificate shall not be valid or obligatory for any purpose
until it shall have been countersigned by the Warrant Agent.
