                               WARRANT AGREEMENT


                                    between


                                CARESIDE, INC.

                            AMERICAN STOCK TRANSFER
                                & TRUST COMPANY


                           Dated as of June 21, 1999
<PAGE>

This Agreement, dated as of June 21, 1999, is between Careside, Inc., a
corporation (the "Company'), and American Stock Transfer & Trust Company, a New
York corporation (the "Warrant Agent").

     WHEREAS, the Company, at or about the time that it is entering into this
Agreement, proposes to issue and sell up to 2,300,000 units ("Units") to public
investors (the "Offering"), which amount includes Units issuable upon the
exercise of the option granted to the representatives of the several
underwriters of the Offering (the "Representatives") to purchase up to 300,000
Units (solely to cover over-allotments in the sale of the Units). Each Unit
consists of one share of the Company's common stock, $0.01 par value per share,
("Common Stock"), and one Warrant (a "Warrant" and collectively, the
"Warrants"), with each Warrant being exercisable to purchase one share of Common
Stock for $9.00, upon the terms and conditions and subject to adjustment in
certain circumstances, all as set forth in this Agreement;

     WHEREAS, the Company proposes to issue to the Representatives, in
connection with the Offering, warrants to purchase up to 200,000 additional
Units, with the terms of such warrants set forth in a separate agreement between
the Company and Paulson Investment Company, Inc. entered into on the date
hereof;

     WHEREAS, the Company wishes to retain the Warrant Agent to act on behalf of
the Company, and the Warrant Agent is willing to so 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; and

     WHEREAS, 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, and whereas, 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
hereto, and may have such letters,

                                       2
<PAGE>

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. After July 16, 1999, each
Warrant Certificate shall entitle the registered holder thereof, subject to the
provisions of this Agreement and of the Warrant Certificate, to purchase, on or
before the close of business on June 16, 2004 (the "Expiration Date"), one fully
paid and nonassessable share of Common Stock for each Warrant evidenced by such
Warrant Certificate, subject to adjustments as provided in Section 6 hereof, for
$9.00 (the "Exercise Price"). Each Warrant Certificate issued as a part of a
Unit offered to the public as described in the recitals, above, shall be dated
June 21, 1999; 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 Standard time, on such date; provided,
however, that if such date is not a business day, it shall mean 5:00 p.m.,
Eastern Standard 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 are authorized or
obligated by law to be closed.

     Each Warrant Certificate shall be executed on behalf of the Company by the
Chairman of the Board or its President or a Vice President, either manually or
by facsimile signature printed thereon, and have affixed thereto the Company's
seal or a facsimile thereof which shall be attested by the Secretary or an
Assistant Secretary of the Company, either manually or by facsimile signature.
Each Warrant Certificate shall be manually 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.

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 to reflect any adjustment or change in the
Exercise Price or the number or kind of shares purchasable thereunder pursuant
to Section 6 hereof and (v) Warrant Certificates issued upon the partial
exercise of Warrant Certificates pursuant to Section 7

                                       3
<PAGE>

hereof. The Warrant Agent is hereby irrevocably authorized to countersign and
deliver, in accordance with the provisions of said Sections 4, 5, 6 and 7, 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 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 banking institution or NASD member and such supporting
documentation as the Warrant Agent or the Company may reasonably require, to the
Warrant Agent at its stock transfer office in New York, New York at any time on
or before the Expiration Date, 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 Warrants 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 Warrants not so transferred.

     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 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 4.

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

                                       4
<PAGE>

     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
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 (i) pay a dividend in, or make a distribution
of, shares of capital stock on its outstanding Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of such shares or (iii)
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, upon exercise of Warrants, shall be entitled to receive, in
substitution for the Common Stock to which such Warrantholder 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 such Warrantholder 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

                                       5
<PAGE>

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
the Chairman or Co-Chairman of the Board or the 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 by the Warrant Agent 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 of such certificate (to be supplied by the
Company if delivered by the Warrant Agent at the Company's request) 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
capital stock or assets of the Company as an entirety or substantially as an
entirety, the surviving corporation formed by such consolidation or merger or
the corporation which shall have acquired such capital stock or 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 for which such Warrant would 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 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

                                       6
<PAGE>

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 Board of Directors of the Company or the Executive Committee of
said Board, 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 class of stock designated as Common Stock in the Amended and Restated
Articles of Incorporation of the Company, or (ii) any other class of stock
resulting from successive changes or reclassification 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 Warrants by any amount for a period of not less
than 20 days. If the Company so reduces the exercise price of the Warrants, it
will give not less than 15 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.

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

                                       7
<PAGE>

any time or in part from time to time after July 16, 1999 and at or prior to the
close of business on the Expiration Date, subject to the provisions of Section
8, 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 in New York, New York, together with payment
to the Company of the Exercise Price (as of the date of such surrender) of the
Warrants then being exercised.  Payment of the Exercise Price 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.  Subject to the terms and
conditions of Section 11, the Company shall pay any and all transfer tax
incurred as a result of any exercise of the Warrants.

     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, 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 10 of the Securities
Act of 1933, as amended, and the Company agrees to supply the Warrant Agent with
sufficient number of prospectuses to effectuate that purpose.

     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 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

                                       8
<PAGE>

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) 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 Warrants outstanding at the time of a redemption may be redeemed at
the option of the Company, in whole, at any time, or in part, from time to time,
and on a pro rata basis (except as provided in Paragraph J below), if at the
time notice of such redemption is given by the Company as provided in Paragraph
F below, the Daily Price has exceeded $14.00 for the 10 consecutive trading days
immediately preceding the date of such notice, at a price equal to $0.05 per
Warrant (the "Redemption Price").  For the purpose of the foregoing sentence,
the term "Daily Price" shall mean, for any relevant day, the closing bid price
or closing price, as the case may be, on that day as reported by the principal
exchange, national market or quotation system on which prices for the Common
Stock are reported.  On the redemption date the holders of record of redeemed
Warrants shall be entitled to payment of the Redemption Price upon surrender of
such redeemed Warrants to the Company at the principal office of the Warrant
Agent in New York, New York.  Notwithstanding anything herein to the contrary,
the Company shall not redeem any Warrants prior to December 16, 1999.  Holders
of record may exercise the Warrants at any time prior to the close of business
on the date of redemption.

     F.  Notice of redemption of Warrants shall be given at least 30 days prior
to the redemption date by mailing, by registered or certified mail, return
receipt requested, a copy of such notice to the Warrant Agent and to all of the
holders of record of Warrants 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.

     G.  With respect to Warrants called for redemption by the Company, from and
after such redemption date, all rights of the Warrantholders shall terminate
(except the right to receive the Redemption Price), 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 Warrants 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.

     H.  The Warrant Agent shall pay to the holders of record of redeemed
Warrants all monies received by the Warrant Agent for the redemption of Warrants
to which the holders of record of such redeemed Warrants who shall have
surrendered their Warrants are entitled.

     I.  Any amounts deposited with the Warrant Agent that are not required for
redemption of Warrants may be withdrawn by the Company.  Any amounts deposited
with the

                                       9
<PAGE>

Warrant Agent that shall be unclaimed after six months after the redemption date
may be withdrawn by the Company, and thereafter the holders of the Warrants
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 Warrants
shall have no right to any such interest.

     J.  If the Company fails to make a sufficient deposit with the Warrant
Agent as provided above, the holder of any Warrants called for redemption may at
the option of the holder (a) by written notice to the Company within 60 days
after the redemption date declare the notice of redemption a nullity as to such
holder, at which time the deposit made by the Company with the Warrant Agent
shall be distributed, on a pro rata basis, to all other Warrantholders 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 J, a notice
of redemption, once mailed by the Company as provided in Paragraph F shall be
irrevocable.

Section 8. Fractional Interests

     The Company shall not be required to issue any Warrant Certificate
evidencing a fraction of a Warrant or to issue fractions of shares of securities
on the exercise of the Warrants.  If any fraction (calculated to the nearest
one-hundredth) of a Warrant or a share of securities would, except for the
provisions of this Section, be issuable upon the exercise of any Warrant, the
Company shall, at its option, either purchase such fraction for an amount in
cash equal to the current value of such fraction computed on the basis of the
Daily Price on the trading day immediately preceding the day upon which such
Warrant Certificate was surrendered for exercise in accordance with Section 7
hereof or issue the required fractional Warrant or share.  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, except as expressly
provided in this Section 8.

Section 9. Reservation of Equity Securities

     The Company covenants that it will at all times reserve and keep available,
free from any preemptive 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
nonassessable.

     The Company covenants that if any Equity Securities, required to be
reserved for the

                                      10
<PAGE>

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 S-1 (Registration No.
333-69207) necessary to permit a public offering of the securities underlying
the Warrants at any and all times during the term of this Agreement; provided,
further, 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 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 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 shareholders 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 its behalf, 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 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 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. Notwithstanding
anything to the contrary in this Section, the Company shall not be required to
deliver such notice if, in the reasonable opinion of the Company's Board of
Directors, based on advice of counsel, such notification would violate any
federal or state securities laws.

     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 moneys received by
the Warrant Agent for the purchase of securities or other property through the
exercise of such Warrants.

                                      12
<PAGE>

     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 in New York, New York.

Section 14. Warrantholder Not Deemed a Shareholder

     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 whatsoever, 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 shareholders 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 shareholders (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.

Section 15. Right of Action

     All rights of action with 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 and 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

                                      13
<PAGE>

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 delivered by the Warrant Agent to the Company
from time to time, or disposed of in accordance with the instructions of the
Company.

Section 18. Concerning the Warrant Agent

     The Company agrees to pay to the Warrant Agent from time to time, on
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 which it expects to incur in its
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 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

                                      14
<PAGE>

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 or the Warrant Agent's in-house counsel), 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, 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 evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by the Chairman or Co-Chairman 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

                                      15
<PAGE>

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 nonassessable.

     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 stockholder, 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 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 the
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

                                      16
<PAGE>

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 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 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 Exercise Price or the number or kind
of shares purchasable under the several Warrant Certificates made in accordance
with the provisions of this Agreement.

THIS CERTIFIES THAT



or registered assigns, is the registered holder of the number of Warrants
("Warrants") set forth above.  Each Warrant entitles the holder thereof to
purchase from Careside, Inc., a corporation incorporated under the laws of the
State of Delaware ("Company"), subject to the terms and conditions set forth
hereinafter and in the Warrant Agreement hereinafter more fully described (the
"Warrant Agreement"), one fully paid and nonassessable share of Common Stock,
$0.01 par value per share, of the Company ("Common Stock") upon presentation and
surrender of this Warrant Certificate with the instructions for the registration
and delivery of Common Stock filled in, at any time after July 16, 1999 and
prior to 5:00 P.M., Eastern Standard time, on June 16, 2004 or, if such Warrant
is redeemed as provided in the Warrant Agreement, at any time prior to the
effective time of such redemption, at the stock transfer office in New York, New
York, of American Stock Transfer & Trust Company, 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 Warrant entitles the holder to purchase one share of Common Stock
for $9.00.  The number and kind of securities or other property for which the
Warrants are exercisable are subject to adjustment in certain events as set
forth in the Warrant Agreement, such as mergers, splits, stock dividends,
recapitalizations, asset sales, stock sales and and similar events, to prevent
dilution.  Subject to the terms of the Warrant Agreement, the Company may redeem
any or all outstanding and unexercised Warrants at any time, upon 30 days'
notice, if the Daily Price has exceeded $14.00 for 10 consecutive trading days
immediately preceding the date of notice of such redemption.  The redemption
price shall be equal to $0.05 per Warrant.  For purposes of the foregoing
sentence, the term "Daily Price" shall mean, for any relevant day, the closing
price on that day as reported by the principal exchange, national or quotation
system on which prices for the Common Stock are reported.  Subject to the terms
of the Warrant Agreement, from and after the redemption date, the

                                      21
<PAGE>

registered holder shall have no rights with respect to the Warrants called for
redemption except for the right to receive $0.05 per Warrant upon surrender of
this Warrant Certificate. All Warrants not theretofore exercised or redeemed
will expire on June 16, 2004. The Company has agreed that it shall not redeem
any Warrants until December 16, 1999.

     This Warrant Certificate is subject to all of the terms, provisions and
conditions of the Warrant Agreement, dated as of June 21, 1999, 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 6100 Bristol Parkway, Culver City, California 90230, Attention:

Chief Financial Officer.

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

     The Company will not be required to honor the exercise of any Warrants if,
in the opinion of the Board of Directors, upon advice of counsel, the sale of
securities upon such exercise would be unlawful.  For example, the Company would
not honor an exercise of Warrants if the sale of securities by the Company upon
exercise of Warrants would violate the securities laws of the United States, any
states thereof or other jurisdictions.  The Company has agreed to use its best
efforts to cause a registration statement to continue to be effective during the
term of the Warrants with respect to such sales under the Securities Act of
1933, as amended, and to take such action under the federal securities laws, and
the laws of various states or other jurisdictions as may be required to cause
the sale of securities upon exercise of the Warrants to be lawful.  Also, in
certain cases, the Company, may, but is not required to, purchase 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 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 Warrants as the Warrant Certificate or Certificates

     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 shareholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof or give or withhold consent to any corporate
action (whether upon any matter submitted to shareholders 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 shareholders (except as provided in the
Warrant Agreement) or to receive dividends or subscription rights or otherwise
until the 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 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 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.
