<PAGE>

4.      Form and Execution of Warrant Certificates.

        (a) The Class A Warrant Certificates and Class B Warrant Certificates
shall be substantially in the forms attached hereto as Exhibits "A" and "B,"
respectively (the provisions of which are incorporated herein), and may have
such letters, numbers or other marks of identification 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. The Warrant Certificates shall be dated as of the date of
issuance thereof by the Company, whether on initial issuance, transfer, exchange
or in lieu of mutilated, lost, stolen or destroyed Warrant Certificates.

        (b) The Warrant Certificates shall be executed on behalf of the Company

printed thereon, and shall have imprinted thereon a facsimile of the Company's
seal. The Warrant Certificates shall be countersigned manually or by facsimile
by the Warrant Agent and shall not be valid for any purpose unless so
countersigned. In the event any officer of the Company who signed any of the
Warrant Certificates shall cease to be such officer of the Company before the
date of issuance of the Warrant Certificates or before countersignature and
delivery by the Warrant Agent, such Warrant Certificates, nevertheless, may be
countersigned, issued and delivered by the Warrant Agent with the same force and
effect as though the person who signed such Warrant Certificates had not ceased
to be such officer of the Company.

5.      Exercise.

        (a) The exercise of Warrants in accordance with this Agreement shall
only be permitted during the Exercise Period.

        (b) Warrants shall be deemed to have been exercised immediately prior to
the close of business on the Exercise Date. The exercise form shall be executed
by the Registered Owner thereof or the Registered Owner's attorney duly
authorized in writing and shall be delivered to the Warrant Agent together with
payment of the Exercise Price for the number of shares as to which the Warrants
are being exercised. Payment shall be made in lawful money of the United States
of America by check or wire transfer payment payable to the order of the Warrant
Agent for the account of the Company.

        (c) The person entitled to receive the number of Warrant Shares
deliverable on such exercise shall be treated for all purposes as the Registered
Owner of such Warrant Shares as of the close of business on the Exercise Date.
The Company shall not be obligated to issue any fraction of a share of Common
Stock on the exercise of Warrants. If Warrants represented by more than one
Warrant Certificate shall be exercised at one time by the same Registered Owner,
the number of full Warrant Shares which shall be issuable on exercise thereof
shall be computed on the basis of the aggregate number of full Warrant Shares
issuable on such exercise.

        (d) The Warrant Agent shall promptly notify the Company in writing of
any exercise and of the number of Warrant Shares to be delivered and shall cause
payment of an amount equal



                                       4
<PAGE>

to the Exercise Price to be made to the Escrow Agent or the Company as
hereinafter provided. The parties contemplate such payments will be made by the
Warrant Agent on a weekly basis and will consist of collected funds only. The
Warrant Agent shall hold any proceeds collected and not yet paid in a
Federally-insured escrow account at a commercial bank selected by agreement of
the Company and the Warrant Agent at all times relevant hereto. Following a
determination by the Warrant Agent that collected funds have been received, the
Warrant Agent shall cause the Transfer Agent to issue share certificates
representing the number of Warrant Shares purchased by the Registered Owner. If
the Warrants are exercised while they are being held in the Escrow Account, the
share certificates representing the Warrant Shares purchased by the Registered
Owner and collected funds in an amount equal to the Exercise Price shall be
deposited into the Escrow Account. If the Warrants are exercised after they have
been released from the Escrow Account, the share certificates representing the
Warrant Shares purchased by the Registered Owner shall be delivered to the
person or persons entitled to receive the same, and collected funds in an amount
equal to the Exercise Price shall be delivered to the Company.

        (e) Expenses incurred by the Warrant Agent, including administrative
costs, and the standard fees imposed by the Warrant Agent for the Warrant
Agent's services, shall be paid by the Company and shall not be deducted from
any collected funds prior to the deposit thereof into the Escrow Account.

        (f) A detailed accounting statement setting forth the number of Warrants
exercised, the number of Warrant Shares issued, the amount of collected funds
received upon exercise of Warrants and all expenses incurred by the Warrant
Agent shall be transmitted to the Company each time a payment of collected funds
is made. Such accounting statement shall serve as an interim accounting for the
Company during the Exercise Period. The Warrant Agent shall render to the
Company, at the completion of the Exercise Period, a complete accounting setting
forth the number of Warrants exercised, the identity of persons exercising such
Warrants, the number of Warrant Shares issued, the amount of collected funds
deposited into the Escrow Account or delivered to the Company, and all expenses
incurred by the Warrant Agent.

        (g) The Company may be required to deliver a prospectus that satisfies
the requirements of Section 10 of the Securities Act of 1933, as amended (the
"Securities Act") with delivery of the Warrant Shares and must have a
registration statement (or a post-effective amendment to an existing
registration statement) effective under the Securities Act in order for the
Company to comply with any such prospectus delivery requirements. The Company
will advise the Warrant Agent of the status of any such registration statement
under the Securities Act and of the effectiveness of the Company's Registration
Statement or lapse of effectiveness.

        (h) No issuance of Warrant Shares shall be made unless there is an
effective registration statement under the Securities Act, and registration or
qualification of the Warrant Shares, or an exemption therefrom, has been
obtained from state or other regulatory authorities in the jurisdiction in which
such Warrant Shares are sold. The Company will provide to the Warrant Agent
written confirmation of all such registrations or qualifications, or an
exemption therefrom, when requested by the Warrant Agent.

6.      Redemption.

        (a) Commencing the Effective Date, the Company may, at its option,
redeem the Class A Warrants in whole, but not in part, for a redemption price of
$.001 per Class A Warrant, on not less than 30 days' written notice to the
Registered Owners. The right to redeem the Class A Warrants may be exercised by
the Company during the Exercise Period only in the event (i) the closing bid
price for the Company's Common Stock, as reported by the market on which the
common stock trades, has exceeded the Exercise Price by $.50 for any 20
consecutive trading days, and (ii) any notice of the call for redemption is
given not more than ten (10) business days after the conclusion of the 20
consecutive trading days referred to in (i) above. In the event the Company
exercises its right to redeem the Class A Warrants, the Expiration Date will be
deemed to be, and the Class A Warrants will be exercisable until the close of
business on, the date fixed for redemption in such notice. If any Class A
Warrant called for redemption is not exercised by such time, it will cease to be
exercisable and the Registered Owner thereof will be entitled only to the
redemption price.

        (b) Commencing the Effective Date, the Company may, at its option,
redeem the Class B Warrants in whole, but not in part, for a redemption price of
$.001 per Class B Warrant, on not less than 30 days' written notice to the
Registered Owners. The right to redeem the Class B Warrants may be exercised by
the Company during the Exercise Period only in the event (i) the closing bid
price for the Company's Common Stock, as reported by the market on which the
common stock trades, has exceeded the Exercise Price by $.50 for any 20
consecutive trading days, and (ii) any notice of the call for redemption is
given not more than ten (10) business days after the conclusion of the 20
consecutive trading days referred to in (i) above. In the event the Company
exercises its right to redeem the Class B Warrants, the Expiration Date will be
deemed to be, and the Class B Warrants will be exercisable until the close of
business on, the date fixed for redemption in such notice. If any Class B
Warrant called for redemption is not exercised by such time, it will cease to be
exercisable and the Registered Owner thereof will be entitled only to the
redemption price.

7.      Reservation of Shares and Payment of Taxes.

        (a) The Company covenants that it will at all times reserve and have
available from its authorized shares of Common Stock such number of shares as
shall then be issuable on exercise of all outstanding Warrants. The Company
covenants that upon exercise of the Warrants and payment of the Exercise Price
therefor, all Warrant Shares issuable upon such exercise shall, at the time of
delivery thereof, be duly and validly issued, fully paid and non-assessable.

        (b) The Company shall pay all documentary, stamp or similar taxes and
other government charges that may be imposed with respect to the issuance of the
Warrants, or the issuance, transfer or delivery of any Warrant Shares on
exercise of the Warrants; provided, however, that if Warrant Shares are to be
delivered in a name other than the name of the Registered Owner of the Warrant
Certificates, no such delivery shall be made unless the person requesting the
same has paid to the Warrant Agent or the Company's Transfer Agent the amount of
any such taxes or charges incident thereto.



                                       6
<PAGE>

        (c) The Warrant Agent is hereby irrevocably authorized as the Transfer
Agent to requisition from time to time certificates representing shares of
Common Stock required upon exercise of the Warrants, and the Company will comply
with all such requisitions.

8.      Exchange and Registration of Transfer.

        (a) Subject to the limitations on transfer described in subsection (e)
below, the Warrant Certificates may be transferred in whole or in part and may
be separately transferred from the stock certificate to which such Warrant
Certificate is attached upon initial issuance, if any, at any time during the
Exercise Period. Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants. Warrant
Certificates to be exchanged shall be surrendered to the Warrant Agent at its
Corporate Office. The Company shall execute and the Warrant Agent shall
countersign, issue and deliver in exchange therefor, the Warrant Certificate or
Certificates which the holder making the exchange shall be entitled to receive.

        (b) The Warrant Agent shall keep transfer books at its Corporate Office
in which Warrant Certificates and the transfer thereof shall be registered.
Subject to the limitations on transfer described in subsection (e) below, on due
presentment for registration of transfer of any Warrant Certificate at such
office, the Company shall execute and the Warrant Agent shall countersign and
deliver to the transferee or transferees a new Warrant Certificate or
Certificates representing an equal aggregate number of Warrants.

        (c) All Warrant Certificates presented for registration of transfer or
exercise shall be duly endorsed or accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Warrant
Agent, duly executed by the Registered Owner thereof or his attorney duly
authorized in writing.

        (d) Prior to due presentment for registration of transfer thereof, the
Company and the Warrant Agent may treat the Registered Owner of any Warrant
Certificate as the absolute owner thereof (notwithstanding any notations of
ownership or writing thereon made by anyone other than the Company or the
Warrant Agent) and the parties to this Agreement shall not be affected by any
notice to the contrary.

        (e) The Warrants may not be transferred while they are being held in the
Escrow Account established at and maintained by the Escrow Agent with the Escrow
Holder pursuant to the Escrow Agreement between the Company, the Escrow Agent
and the Escrow Holder except by will or the laws of descent and distribution, or
pursuant to a qualified domestic relations order as defined by the Internal
Revenue Code of 1986, as amended, or Title I of the Employment Retirement Income
Security Act (ERISA), or the rules thereunder.

9.      Loss or Mutilation. On receipt by the Company and the Warrant Agent of
evidence satisfactory to them of the ownership of and the loss, theft,
destruction or mutilation of any Warrant Certificate, the Company shall execute
and the Warrant Agent shall countersign and deliver in lieu thereof, a new
Warrant Certificate representing an equal aggregate number of Warrants. In the
case of



                                       7
<PAGE>

loss, theft or destruction of any Warrant Certificate, the Registered Owner
requesting issuance of a new Warrant Certificate shall be required to obtain an
indemnity bond from an approved surety bonding company in favor of the Company
and Warrant Agent in an amount satisfactory to each of them. In the event a
Warrant Certificate is mutilated, such Warrant Certificate shall be surrendered
and canceled by the Warrant Agent prior to delivery of a new Warrant
Certificate. Applicants for a substitute Warrant Certificate shall also comply
with such other regulations and pay such other reasonable charges as the Warrant
Agent may prescribe.

10.     Adjustment of Exercise Price and Warrant Shares.

        (a) If at any time prior to the expiration of the Warrants by their
terms or by exercise, the Company increases or decreases the number of its
issued and outstanding shares of Common Stock, or changes in any way the rights
and privileges of such shares of Common Stock, by means of (i) the payment of a
share dividend or the making of any other distribution on such shares of Common
Stock payable in its shares of Common Stock, (ii) a split or subdivision of
shares of Common Stock, or (iii) a consolidation or combination of shares of
Common Stock, then the Exercise Price in effect at the time of such action and
the number of Warrants required to purchase each Warrant Share at that time
shall be proportionately adjusted so that the numbers, rights and privileges
relating to the Warrant Shares then purchasable upon the exercise of the
Warrants shall be increased, decreased or changed in like manner, for the same
aggregate purchase price set forth in the Warrants, as if the Warrant Shares
purchasable upon the exercise of the Warrants immediately prior to the event had
been issued, outstanding, fully paid and non-assessable at the time of that
event. Any dividend paid or distributed on the shares of Common Stock in shares
of any other class of shares of the Company or securities convertible into
shares of Common Stock shall be treated as a dividend paid in shares of Common
Stock to the extent shares of Common Stock are issuable on the payment or
conversion thereof.

        (b) In the event, prior to the expiration of the Warrants by their terms
or by exercise, the Company shall be recapitalized by reclassifying its
outstanding shares of Common Stock into shares with a different par value, or by
changing its outstanding shares of Common Stock to shares without par value or
in the event of any other material change in the capital structure of the
Company or of any successor corporation by reason of any reclassification,
recapitalization or conveyance, prompt, proportionate, equitable, lawful and
adequate provision shall be made whereby any Registered Owner of the Warrants
shall thereafter have the right to purchase, on the basis and the terms and
conditions specified in this Agreement, in lieu of the Warrant Shares
theretofore purchasable on the exercise of any Warrant, such securities or
assets as may be issued or payable with respect to or in exchange for the number
of Warrant Shares theretofore purchasable on exercise of the Warrants had such
reclassification, recapitalization or conveyance not taken place; and in any
such event, the rights of any Registered Owner of a Warrant to any adjustment in
the number of Warrant Shares purchasable on exercise of such Warrant, as set
forth above, shall continue and be preserved in respect of any stock, securities
or assets which the Registered Owner becomes entitled to purchase.

        (c) In the event the Company, at any time prior to the expiration of the
Warrants by their terms or by exercise, shall sell all or substantially all of
its property, or dissolves, liquidates or winds up its affairs, prompt,
proportionate, equitable, lawful and adequate provision shall be



                                       8
<PAGE>

made as part of the terms of such sale, dissolution, liquidation or winding up
such that the Registered Owner of a Warrant may thereafter receive, on exercise
thereof, in lieu of each Warrant Share which the Registered Owner would have
been entitled to receive, the same kind and amount of any stock, securities or
assets as may be issuable, distributable or payable on any such sale,
dissolution, liquidation or winding up with respect to each share of Common
Stock of the Company; provided, however, that in the event of any such sale,
dissolution, liquidation or winding up, the right to exercise the Warrants shall
terminate on a date fixed by the Company, such date to be not earlier than 5:00
P.M., Mountain Time , on the 30th day next succeeding the date on which notice
of such termination of the right to exercise the Warrants has been given by mail
to the Registered Owners thereof at such addresses as may appear on the books of
the Warrant Agent.

        (d) Upon exercise of the Warrants by the Registered Owners, the Company
shall not be required to deliver fractions of Warrant Shares; provided, however,
that the Company shall make prompt, proportionate, equitable, lawful and
adequate provisions in respect of any such fraction of one Warrant Share either
on the basis of adjustment in the then applicable Exercise Price or a purchase
of the fractional interest at the market price of the Company's shares of Common
Stock or such other reasonable basis as the Company may determine.

        (e) In the event, prior to expiration of the Warrants by exercise or by
their terms, the Company shall determine to take a record of the holders of its
shares of Common Stock for the purpose of determining stockholders entitled to
receive any stock dividend, distribution or other right which will cause any
change or adjustment in the number, amount, price or nature of the shares of
Common Stock or other stock, securities or assets deliverable on exercise of the
Warrants pursuant to the foregoing provisions, the Company shall give to the
Registered Owners of the Warrants at the addresses as may appear on the books of
the Warrant Agent at least 30 days' prior written notice to the effect that it
intends to take such a record. Such notice shall specify the date as of which
such record is to be taken; the purpose for which such record is to be taken;
and the number, amount, price and nature of the shares of Common Stock or other
stock, securities or assets which will be deliverable upon exercise of the
Warrants after the action for which such record will be taken has been
completed. Without limiting the obligation of the Company to provide notice to
the Registered Owners of the Warrants of any corporate action hereunder, the
failure of the Company to give notice shall not invalidate such corporate action
of the Company.

        (f) The Warrants shall not entitle the Registered Owner thereof to any
of the rights of stockholders or to any dividend declared on the shares of
Common Stock unless the Warrant is exercised and the Warrant Shares purchased
prior to the record date fixed by the Board of Directors of the Company for the
determination of holders of shares of Common Stock entitled to such dividend or
other right.

       (g) Any reduction in the applicable Exercise Price shall be effective
upon written notice to the Warrant Agent, which notice shall be given pursuant
to a duly and validly authorized resolution of the Board of Directors of the
Company.

        (a) The Warrant Agent acts hereunder as agent and in a ministerial
capacity for the Company, and its duties shall be determined solely by the
provisions hereof. The Warrant Agent shall not, by issuing and delivering
Warrant Certificates or by any other act hereunder, be deemed to make any
representations as to the validity, value or authorization of the Warrant
Certificates or the Warrants represented thereby or of the Warrant Shares or
other property delivered on exercise of any Warrant.

        (b) The Warrant Agent shall not be under any duty or responsibility to
any holder of the Warrant Certificates to make or cause to be made any

may require any such adjustment. The Warrant Agent shall not (i) be liable for
any recital or statement of fact contained herein or for any action taken or
omitted by it in reliance on any Warrant Certificate or other document or
instrument believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties, (ii) be responsible for any failure on
the part of the Company to comply with any of its covenants and obligations
contained in this Agreement or in the Warrant Certificates, or (iii) be liable
for any act or omission in connection with this Agreement except for its own
negligence or willful misconduct.

        (c) The Warrant Agent may at any time consult with counsel satisfactory
to it (who may be counsel for the Company) and shall incur no liability or
responsibility for any action taken or omitted by it in good faith in accordance
with the opinion or advice of such counsel.

        (d) Any notice, statement, instruction, request, direction, order or
demand of the Company shall be sufficiently evidenced by an instrument signed by
an officer of the Company. The Warrant Agent shall not be liable for any action
taken or omitted by it in accordance with such notice, statement, instruction,
request, direction, order or demand.

        (e) The Company agrees to pay the Warrant Agent reasonable compensation
for its services hereunder and to reimburse the Warrant Agent for its reasonable
expenses. The Company further agrees to indemnify the Warrant Agent and save it
harmless against any and all losses, expenses and liabilities, including
judgments, costs and counsel fees, for any action taken or omitted by the
Warrant Agent in the execution of its duties and powers hereunder, except
losses, expenses and liabilities arising as a result of the Warrant Agent's
negligence or willful misconduct.

        (f) The Warrant Agent may resign its duties or the Company may terminate
the Warrant Agent and the Warrant Agent shall be discharged from all further

notice to the other party. Upon notice of such resignation or termination, the
Warrant Agent shall cause a copy of such notice to be mailed to the Registered

within a period of 30 days after notice of such resignation or termination, then
the Registered Owner of any Warrant Certificate may apply to any court of
competent jurisdiction for the appointment of a new warrant agent. Any new
warrant agent shall have its principal office in the United States. After
acceptance in writing of an appointment of a new warrant agent is received by
the Company, such new warrant agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named herein as
the warrant agent, without any further assurance, conveyance, act or deed;
provided, however, if it shall be necessary or expedient to execute and deliver
any further assurance, conveyance, act or deed, the same shall be done at the
expense of the Company and shall be legally and validly executed and delivered
by the resigning Warrant Agent. The Company shall file a notice of appointment
of a new warrant agent with the resigning Warrant Agent and shall forthwith
cause a copy of such notice to be mailed to the Registered Owner of each Warrant
Certificate.

        (g) Any corporation into which the Warrant Agent or any new warrant
agent may be converted or merged, or any corporation resulting from any
consolidation to which the Warrant Agent or any new warrant agent shall be a
party, or any corporation succeeding to the corporate trust business of the
Warrant Agent shall be a successor warrant agent under this Agreement without
any further act, provided that such corporation is eligible for appointment as a
successor to the Warrant Agent. Any such successor warrant agent shall promptly
cause notice of its succession as warrant agent to be mailed to the Company and
to the Registered Owner of each Warrant Certificate.

        (h) The Warrant Agent, its officers or directors and it subsidiaries or
affiliates may buy, hold or sell Warrants or other securities of the Company and
otherwise deal with the Company in the same manner and to the same extent and
with like effect as though it were not the Warrant Agent. Nothing herein shall
preclude the Warrant Agent from acting in any other capacity for the Company or
for any other legal entity.

12.     Modification of Agreement. The Warrant Agent and the Company may by
supplemental agreement make any changes or corrections in this Agreement without
the approval of any holders of Warrants (i) that they shall deem appropriate to
cure any ambiguity or to correct any defective or inconsistent provision or
mistake or error herein contained, (ii) that they may deem necessary or
desirable and which shall not adversely affect the interests of the Registered
Owners of Warrant Certificates; (iii) that they may deem necessary or desirable
to decrease the Exercise Price as provided for in Section 1(f) hereof; (iv) or
which may be required by law; provided, however, this Agreement shall not
otherwise be modified, supplemented or altered in any respect except with the
consent in writing of the Registered Owners of Warrant Certificates representing
not less than a majority of the Warrants outstanding. Additionally, no change in
the number or nature of the Warrant Shares purchasable on exercise of a Warrant
or the Exercise Price thereof (other than a decrease in the Exercise Price as
provided in Section 1(f) hereof) shall be made without the consent in writing of
the Registered Owner of the Warrant Certificate representing such Warrant, other
than such changes as are specifically permitted or prescribed by this Agreement.

                                                               Warrant Agreement

                          PURCHASE WARRANT CERTIFICATE

                              GREENGATE CORPORATION


        This certifies that for value received, _______________ or registered
assigns (the "Registered Owner"), is the owner of _______ Class A redeemable
common stock purchase warrants (the "Warrants"), each of which Warrants entitles
the Registered Owner to purchase during the period commencing _________, 200_
and expiring at 5:00 P.M. Mountain time on ______, 200_, one fully paid and
non-assessable share of common stock, $.0001 par value per share, of Greengate
Corporation, a Delaware corporation (the "Company"), upon payment of $1.00 per
share (the "Exercise Price"); provided, however, that the number of shares of
the Company's common stock purchasable upon exercise of each Warrant may be
increased or reduced and the Exercise Price adjusted in the event of certain
contingencies provided for in the Warrant Agreement described below. Payment of
the Exercise Price of Warrants represented by this Warrant Certificate shall be
made in lawful money of the United States of America by check or wire transfer
payment payable to the order of the Warrant Agent for the account of the
Company.

        This Warrant Certificate and each Warrant represented hereby are issued
pursuant to and are subject in all respects to the terms and conditions
contained in the Warrant Agreement dated as of ___________, 2002 between the
Company and Corporate Stock Transfer, Inc. ("Warrant Agent"). Copies of the
Warrant Agreement are on file at the office of the Warrant Agent.

        In order to exercise these Warrants, the form of election to purchase on
the reverse side must be properly completed and executed. If Warrants
represented by this Warrant Certificate are exercised with respect to fewer than
all shares purchasable, certificates representing Warrants to purchase the
remaining number of shares will be issued. The Company shall not be required to
issue fractions of shares upon the exercise of Warrants.

        Warrants are transferable at the office of the Warrant Agent (or of its
successor as Warrant Agent) by the Registered Owner thereof in person or by
attorney duly authorized in writing, in the manner and subject to the
limitations on transfer set forth in the Warrant Agreement, upon surrender of
the Warrant Certificate and the payment of transfer taxes, if any. Upon any such
transfer, a new Warrant Certificate or new Warrant Certificates of different
denominations, of like tenor and representing in the aggregate the right to
purchase a like number of shares of the Company's common stock, will be issued
to the transferee in exchange for this Warrant Certificate, subject to the
limitations set forth in the Warrant Agreement.



                                       14
<PAGE>

        This Warrant Certificate, when surrendered at the office of the Warrant
Agent (or of its successor as Warrant Agent) by the Registered Owner in person
or by attorney duly authorized in writing, may be exchanged for any other
Warrant Certificates of different denominations, of like tenor and representing
in the aggregate the right to purchase a like number of shares, subject to the
limitations 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
securities purchasable upon the exercise of Warrants are closed for any reason,
the Company shall not be required to make delivery of certificates for the
securities purchasable upon such exercise until the date of the reopening of
said transfer books.

        The Registered Owner shall not be entitled to any of the rights of a
stockholder of the Company prior to exercise hereof.

        Subject to the provisions of the Warrant Agreement, the Warrants may be
redeemed at the option of the Company for a redemption price of $.001 per
Warrant on not less than 30 days' notice, provided that (i) the closing bid
price for the Company's common stock, as reported by the market on which the
common stock trades, has exceeded the Exercise Price by $.50 for any 20
consecutive trading days, and (ii) any notice of the call for redemption is
given not more than 10 business days after the conclusion of such 20 consecutive
trading days. In the event the Company exercises its right to redeem the
Warrants, the Warrants will be exercisable until the close of business on the
date fixed for redemption in such notice. If any Warrant called for redemption
is not exercised by such date, it will cease to be exercisable and the
Registered Owner will be entitled only to the redemption price.

        Prior to due presentment for registration or transfer thereof, the
Company and the Warrant Agent may treat the Registered Owner as the absolute
owner hereof and of each Warrant represented hereby (notwithstanding any
notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary, except as provided in the
Warrant Agreement.

        This Warrant Certificate is not valid unless countersigned by the
Warrant Agent.

or by attorney duly authorized in writing, may be exchanged for any other
Warrant Certificates of different denominations, of like tenor and representing
in the aggregate the right to purchase a like number of shares, subject to the
limitations 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
securities purchasable upon the exercise of Warrants are closed for any reason,
the Company shall not be required to make delivery of certificates for the
securities purchasable upon such exercise until the date of the reopening of
said transfer books.

        The Registered Owner shall not be entitled to any of the rights of a
stockholder of the Company prior to exercise hereof.

        Subject to the provisions of the Warrant Agreement, the Warrants may be
redeemed at the option of the Company for a redemption price of $.001 per
Warrant on not less than 30 days' notice, provided that (i) the closing bid
price for the Company's common stock, as reported by the market on which the
common stock trades, has exceeded the Exercise Price by $.50 for any 20
consecutive trading days, and (ii) any notice of the call for redemption is
given not more than 10 business days after the conclusion of such 20 consecutive
trading days. In the event the Company exercises its right to redeem the
Warrants, the Warrants will be exercisable until the close of business on the
date fixed for redemption in such notice. If any Warrant called for redemption
is not exercised by such date, it will cease to be exercisable and the
Registered Owner will be entitled only to the redemption price.

        Prior to due presentment for registration or transfer thereof, the
Company and the Warrant Agent may treat the Registered Owner as the absolute
owner hereof and of each Warrant represented hereby (notwithstanding any
notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary, except as provided in the
Warrant Agreement.

        This Warrant Certificate is not valid unless countersigned by the
Warrant Agent.
