                                CARESIDE, INC.

                    SERIES B CONVERTIBLE PREFERRED WARRANT
                    --------------------------------------

Warrant No. RC-P-1                            Dated:  September 13, 2000

     Careside, Inc., a Delaware corporation (the "Company"), hereby certifies
that, for value received, Roycap, Inc., or its registered assigns (the
"Holder"), is entitled, subject to the terms and conditions set forth herein, to
purchase from the Company a total of 200 shares of Series B Convertible
Preferred Stock, $.01 with a Stated Value of $5,000 per share (the "Series B
Preferred"), of the Company (each such share, a "Warrant Share" and all such
shares, the "Warrant Shares").  Unless specified otherwise, capitalized terms
used herein have the definitions set forth in Exhibit A attached hereto:
                                              ---------

     1.   Registration of Warrant.  The Company shall register this Warrant upon
          -----------------------
records to be maintained by the Company for that purpose (the "Warrant
Register") in the name of the record Holder hereof from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

     2.   Registration of Transfers and Exchanges.
          ---------------------------------------

          (a)  This Warrant may only be transferred pursuant to an effective
registration statement under the Securities Act, to the Company or pursuant to
an available exemption from or in a transaction not subject to the registration
requirements of the Securities Act. In connection with any transfer of this
Warrant other than pursuant to an effective registration statement or to the
Company, the Company may require the transferor thereof to provide to the
Company an opinion of counsel selected by the transferor, the form and substance
of which opinion shall be reasonably satisfactory to the Company, to the effect
that such transfer does not require registration of such Warrant under the
Securities Act. Holder agrees to the imprinting, so long as
<PAGE>

is required by this Section 2(a), of a legend substantially similar to that
first above written on any New Warrant (as defined below). Any such transferee
shall agree in writing to be bound by the terms of this Warrant and shall have
the rights of Holder under this Warrant. The Company shall register the transfer
of this Warrant in the Warrant Register, upon surrender of this Warrant, with
the Form of Assignment attached hereto duly completed and signed, to the
Transfer Agent or to the Company at its address for notice set forth in Section
11. Upon any such registration or transfer, a new warrant to purchase Series B
Preferred, in substantially the form of this Warrant (any such new warrant, a
"New Warrant"), evidencing this Warrant so transferred shall be issued to the
transferee. The acceptance of the New Warrant by the transferee thereof shall be
deemed the acceptance of such transferee of all of the rights and obligations of
a Holder of this Warrant.

          (b)  This Warrant is exchangeable, upon the surrender hereof by the
Holder to the Company at its address for notice set forth in Section 11 for a
New Warrant, evidencing in the aggregate the right to purchase the number of
Warrant Shares which may then be purchased hereunder. Any such New Warrant will
be dated the date of such exchange.

     3.   Duration, Exercise and Redemption of Warrants.
          ---------------------------------------------

          (a)  Company Call Option.
               -------------------

               (i)    Subject to the terms and conditions set forth herein, the
Company may at any time during the Exercise Period (as defined in Section 3(b))
deliver written notices to the Holder (each, a "Call Notice" and the Trading Day
a Call Notice is delivered or if delivered after market close, the next day, a
"Delivery Date"), of the Company's election to call the Warrant for a price of
$.01. Notwithstanding anything to the contrary set forth in this Warrant: (1) no
Call Notice may be delivered until the expiration of the Call Expiration Time
(as defined below) for the immediately preceding Call Notice, and (2) no Call
Notice may be delivered unless the conditions set forth in Section 3(a)(iii)
have been either satisfied by the Company or waived by the Holder. "Trading Day"
means (a) a day on which the shares of Common Stock are traded on the American
Stock Exchange or on a Subsequent Market (as defined in Section 3(a)(iii)(G) on
which the shares of Common Stock are then listed or quoted, or (b) if the shares
of Common Stock are not listed on the American Stock Exchange or a Subsequent
Market, a day on which the shares of Common Stock are traded in the over-the-
counter market, as reported by the OTC Bulletin Board, or (c) if the shares of
Common Stock are not quoted on the OTC Bulletin Board, a day on which the shares
of Common Stock are quoted in the over-the-counter market as reported by the
National Quotation Bureau Incorporated (or any similar organization or agency
succeeding its functions of reporting prices); provided, however, that in the
                                               --------  -------
event that the shares of Common Stock are not listed or quoted as set forth in
(a), (b) and (c) hereof, then Trading Day shall mean a Business Day.

               (ii)   The Warrant, if and to the extent subject to a Call
Notice, will be canceled and of no further effect from and after 5:30 p.m. (New
York City time) on the second Trading Day following the Delivery Date (the "Call
Expiration Time"), unless between the Delivery Date and the Call Expiration Time
the Holder notifies the Company in writing that it will exercise this Warrant at
the Exercise Price per share set forth in Section 3(c). Such exercise shall be
in accordance with Section 3(b)(ii).

                                      -2-
<PAGE>

               (iii)  The right of the Company to deliver a Call Notice is
subject to the satisfaction by the Company or waiver by the Holder, at or before
the applicable Call Expiration Time, of each of the following conditions (and,
if after delivery thereof and on the applicable Exercise Date, any of the
following conditions shall cease to be met, such Call Notice, at the option of
the Holder, shall be null and void ab initio):

                      (A)  The Company shall have performed, satisfied and
                           complied in all material respects with all covenants
                           (including timely delivery of Warrant Shares in
                           accordance with Section 3(a)), agreements and
                           conditions of the Transaction Documents (as defined
                           in the Purchase Agreement) to be performed, satisfied
                           or complied with by the Company at or prior to the
                           applicable Delivery Date and Call Expiration Time;

                      (B)  The Underlying Shares Registration Statement shall be
                           effective on the Delivery Date, not subject to any
                           stop order or suspension and the Company shall not
                           have received any notice from the Commission that it
                           intends to issue a stop order or suspension;

                      (C)  No statute, rule, regulation, executive order,
                           decree, ruling or injunction shall have been enacted,
                           entered, promulgated or endorsed by any court or
                           governmental authority of competent jurisdiction and
                           in force on the Delivery Date which prohibits the
                           consummation of any of the transactions contemplated
                           by the Transaction Documents;

                      (D)  Since the Closing Date (as defined in the Purchase
                           Agreement), no event or series of events which

                           Material Adverse Effect (as defined in the Purchase
                           Agreement) and no Change of Control Transaction shall
                           have occurred;

                      (E)  Since the Closing Date, trading in the Common Stock
                           shall not have been suspended by the Securities and
                           Exchange Commission for a period in excess of five
                           (5) consecutive Trading Days or ten (10) Trading Days
                           in the aggregate (which need not be consecutive
                           Trading Days) in any one (1) year period, except for
                           any suspensions of trading of not more than one
                           Trading Day solely to permit dissemination of
                           material information regarding the Company;

                      (F)  On the Delivery Date, the Common Stock shall be
                           trading on the American Stock Exchange, or on the

          (b)  Exercise By Holder.
               ------------------

               (i)    At any time during the period (the "Exercise Period")
beginning twenty (20) days after the Effective Time and ending sixty (60) days

all, but not less than all, of the Warrant Shares in accordance with the terms
hereof.

               (ii)   The Holder may purchase Warrant Shares hereunder by
delivering to the Company, at its address for notice set forth in Section 10, a
completed Form of Election to Purchase in the form attached hereto, together
with the payment of the Exercise Price. An "Exercise Date" means the date of the
delivery (which may be made via facsimile and wire transfer, respectively) of
the Form of Election to Purchase and applicable Exercise Price.

               (iii)  After the Company receives a Form of Election to Purchase
and the Exercise Price, the Company shall promptly (but in no event later than
three (3) business days thereafter) request that the Company's transfer agent
issue and deliver to or upon the written order of the Holder and in such name or
names as the Holder may designate, a certificate for the Warrant Shares issuable
upon such exercise, free of restrictive legends except as required by the
Purchase Agreement. If the Company fails to deliver to the Holder the
certificate or certificates pursuant to this Section within the time specified
in above, the Holder shall be entitled by written notice to the Company at any
time on or before its receipt of such certificate or certificates thereafter, to
rescind such exercise.

          (c)  Exercise Price.
               ---------------

               The "Exercise Price" applicable to the exercise of this Warrant
is One Million Dollars ($1,000,000).

     4.   Payment of Taxes.  The Company will pay all documentary stamp taxes
          ----------------
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or this Warrant in a name other than that
of the Holder.  The Holder shall be responsible for all other tax liability that
may arise as a result of holding or transferring this Warrant or receiving
Warrant Shares upon exercise hereof.

     5.   Replacement of Warrant.  If this Warrant is mutilated, lost, stolen or
          ----------------------
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it.  Applicants for a New Warrant under such

                                      -4-

all times reserve and keep available out of the aggregate of its authorized but
unissued Series B Convertible Preferred Stock, solely for the purpose of
enabling it to issue Warrant Shares upon exercise of this Warrant as herein
provided, the number of Warrant Shares which are then issuable and deliverable
upon the exercise of this entire Warrant, free from preemptive rights or any
other actual contingent purchase rights of persons other than the Holder. The
Company covenants that all Warrant Shares that shall be so issuable and
deliverable shall, upon issuance and the payment of the applicable Exercise
Price in accordance with the terms hereof, be duly and validly authorized,
issued and fully paid and nonassessable.

     7.   Payment of Exercise Price. The Holder shall pay the Exercise Price
          -------------------------
upon Exercise of the Warrant by delivery of immediately available funds.

     8.   Fractional Shares. The Company shall not be required to issue or cause
          -----------------
to be issued fractional Warrant Shares on the exercise of this Warrant. The
number of full Warrant Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of this Warrant so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section, be issuable on
the exercise of this Warrant, the Company shall pay an amount in cash equal to
the Exercise Price multiplied by such fraction.

     9.   Notices.  Any and all notices or other communications or deliveries
          -------
hereunder shall be in writing and shall be deemed given and effective on the
earliest of (i) the date of transmission, if such notice or communication is

          -------------
Warrant.  Upon thirty (30) days' notice to the Holder, the Company may appoint a
new warrant agent.  Any corporation into which the Company or any new warrant
agent may be merged or any corporation resulting from any consolidation to which
the Company or any new warrant agent shall be a party or any corporation to
which the Company or any new warrant agent transfers substantially all of its

cause notice of its succession as warrant agent to be mailed (by first class

                               WARRANT AGREEMENT

     THIS WARRANT AGREEMENT (the "Agreement"), dated as of September 13, 2000,
is entered into by and between Careside, Inc., a Delaware corporation (the
"Company"), and RoyCap, Inc. (the "Purchaser").

                             WITNESSETH:

     WHEREAS, the Company proposes to sell to Purchaser pursuant to a Securities
Purchase Agreement, dated as of the date hereof (the "Securities Purchase
Agreement"), by and between the Company and the Purchaser, 150 shares of Series
B Convertible Preferred Stock of the Company (the "Series B Preferred"), a
warrant to purchase 200 shares of Series B Preferred, a warrant (the "Warrant")
to purchase 25,000 shares of common stock of the Company, par value $0.01 per
share (the "Common Stock") at an exercise price as described herein (the Common
Stock issuable upon exercise of this Warrant being referred to herein as the
"Warrant Shares") and a warrant to purchase up to 4,000,000 Shares of Common
Stock.

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

                                   ARTICLE I
                              WARRANT CERTIFICATES

     Section 1.1  Forms of Warrant Certificates. The warrant certificates (the
                  -----------------------------
"Warrant Certificates") shall be issued substantially in the form of Exhibit A
                                                                     ---------
attached hereto, together with the form of the election to purchase (the
"Election to Purchase") and assignment (the "Assignment") to be attached
thereto, and, in addition, may have such letters, numbers or other marks of
identification or designation and such legends, summaries, or endorsements
stamped, printed, lithographed or engraved thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as, in any particular case, may be required in the opinion of counsel for the
Company, to comply with any law or with any rule or regulation of any regulatory
authority or agency, or to conform to customary usage.
<PAGE>

     Section 1.2  Execution of Warrant Certificates. The Warrant Certificates
                  ----------------------------------
shall be executed on behalf of the Company by its Chairman or President or any
Vice President and attested to by its Secretary or Assistant Secretary, either
manually or by facsimile signature printed thereon. In case any authorized
officer of the Company who shall have signed any of the Warrant Certificates
shall cease to be an officer of the Company either before or after delivery
thereof by the Company to any Purchaser, the signature of such person on such
Warrant Certificates shall be valid nevertheless and such Warrant Certificates
may be issued and delivered to those persons entitled to receive the Warrants
represented thereby with the same force and effect as though the person who
signed such Warrant Certificates had not ceased to be an officer of the Company.

     Section 1.3  Registration of Warrant Certificates. The Company shall number
                  -------------------------------------
and keep a registry for the Warrant Certificates in a register as they are
needed. The Company may deem and treat the registered holder(s) of the Warrant
Certificates (the "Holders") as the absolute owner(s) thereof for all purposes.

     Section 1.4  Exchange and Transfer of Warrant Certificates. The Warrants
                  ----------------------------------------------
(and any Warrant Shares issued upon exercise of the Warrants) shall bear such
restrictive legend or legends as may be required by the Securities Purchase
Agreement and as may be required by law and shall be transferable only in
accordance with the terms of this Agreement and the Securities Purchase
Agreement.

     The Company may from time to time note the transfer of any outstanding
Warrant Certificates in a warrant register to be maintained by the Company upon
surrender thereof accompanied by a written instrument or instruments of transfer
in form satisfactory to the Company duly executed by the Holder or Holders
thereof or by the duly appointed legal representative thereof or by a duly
authorized attorney. Upon any such registration of transfer, a new Warrant
Certificate shall be issued to the transferee(s).

     Warrant Certificates may be exchanged at the option of the Holder(s)
thereof, when surrendered to the Company at the address set forth in Section 4.5
hereof for another Warrant Certificate or Warrant Certificates of like tenor and
representing in the aggregate a like number of Warrant Shares: provided that the
                                                               --------
Company shall not be required to issue any Warrant Certificate representing any
fractional Warrant Shares.

     Section 1.5  Lost, Stolen, Mutilated or Destroyed Warrant Certificates. If
                  ----------------------------------------------------------
any Warrant Certificate shall be mutilated, lost, stolen or destroyed, the
Company shall issue, execute and deliver, in exchange and substitution for and
upon cancellation of a mutilated Warrant Certificate, or in lieu of or in
substitution for a lost, stolen or destroyed Warrant Certificate, a new Warrant
Certificate representing an equivalent number of Warrants or Warrant Shares. If
required by the Company, the Holder of the mutilated, lost, stolen or destroyed
Warrant Certificate must provide indemnity sufficient to protect the Company
from any loss which it may

                                      -2-
<PAGE>

suffer if the Warrant Certificate is replaced. Any such new Warrant Certificate
shall constitute an original contractual obligation of the Company, whether or
not the allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall
be at any time enforceable by anyone.

     Section 1.6  Cancellation of Warrant Certificates. Any Warrant Certificate
                  -------------------------------------
surrendered upon the exercise of Warrants or for exchange or transfer, or
purchased or otherwise acquired by the Company, shall be canceled and shall not
be reissued by the Company; and, except as provided in Section 2.5 hereof in
case of the exercise of less than all of the Warrants evidenced by a Warrant
Certificate or in Section 1.4 in an exchange or transfer, no Warrant Certificate
shall be issued hereunder in lieu of such canceled Warrant Certificate. Any
Warrant Certificate so canceled shall be destroyed by the Company.

                                  ARTICLE II
                WARRANT EXERCISE PRICE AND EXERCISE OF WARRANTS

     Section 2.1  Exercise Price. Each Warrant Certificate shall, when signed by
                  ---------------
the Chairman or President or any Vice President and attested to by the Secretary
or Assistant Secretary of the Company, entitle the Holder thereof to purchase
from the Company, subject to the terms and conditions of this Agreement, the
number of fully paid and nonassessable Warrant Shares evidenced thereby at a
purchase price per share of $5.625 per share (the "Initial Exercise Price")
(120% of the Closing Price of the Common Stock on the date prior to the date
hereof) or such adjusted number of Warrant Shares at such adjusted purchase
price as may be established from time to time pursuant to the provisions of
Article III hereof, payable in full in accordance with Section 2.3 hereof, at
the time of exercise of the Warrant. Except as the context otherwise requires,
the term "Exercise Price" as used in this Agreement shall mean the purchase
price of one share of Common Stock, reflecting all appropriate adjustments made
in accordance with the provisions of Article III hereof.

     Section 2.2  Registration of Warrants and Warrant Shares. The Company shall
                  --------------------------------------------
secure the effective registration of the Warrant Shares for resale under the
Securities Act of 1933, as amended (the "Securities Act") upon the terms and
subject to the conditions set forth in the Registration Rights Agreement
executed by the parties on the date hereof. Promptly after a registration
statement under the Securities Act covering the Warrant Shares has become
effective, the Company shall cause notice thereof together with a copy of the
prospectus covering the Warrant Shares to be mailed to each registered Holder.

     Section 2.3  Procedure for Exercise of Warrants. The Warrants may be
                  -----------------------------------
exercised prior to the Expiration Date (as hereinafter defined) at the Exercise
Price at any time after the date hereof. The Warrants shall expire on September
13, 2005, at 5:00 p.m., EST (the "Expiration Date"). The Warrants may be
exercised by surrendering the Warrant Certificates representing such Warrants to
the Company at its address set forth in Section 4.5 hereof, together with the
Election to Purchase duly completed and executed, accompanied by payment in
full, as set forth

                                      -3-
<PAGE>

below, to the Company of the Exercise Price for each Warrant Share in respect of
which such Warrants are being exercised. Such Exercise Price shall be paid in
full by (i) cash or a certified check or a wire transfer in same day funds in an
amount equal to the Exercise Price multiplied by the number of Warrant Shares
then being purchased or (ii) delivery to the Company of that number of shares of
Common Stock having a Fair Market Value (as hereinafter defined) equal to the
Exercise Price multiplied by the number of Warrant Shares then being purchased.
In the alternative, the Holder of a Warrant Certificate may exercise its right
to purchase some or all of the Warrant Shares subject to such Warrant
Certificate, on a net basis, such that, without the exchange of any funds, such
Holder receives that number of Warrant Shares subscribed to pursuant to such
Warrant Certificate less that number of shares of Common Stock having an
aggregate Fair Market Value at the time of exercise equal to the aggregate
Exercise Price that would otherwise have been paid by such Holder for the number
of Warrant Shares subscribed to pursuant to such Warrant Certificate
(hereinafter, a "Net Cashless Exercise").

     As used herein: (a) the term "Fair Market Value," on a per share basis,
means the average of the daily Closing Prices (as hereinafter defined) of the
Common Stock for the five (5) consecutive Trading Days (as hereinafter defined)
ending the Trading Day immediately preceding the Date of Exercise; (b) the term
"Date of Exercise" with respect to any Warrant means the date on which such
Warrant is exercised as provided herein; (c) the term "Closing Price" for any
date shall mean the last sale price reported in The Wall Street Journal regular
                                                    -------------------
way or, in case no such reported sale takes place on such date, the average of
the last reported bid and asked prices regular way, in either case on the
principal national securities exchange on which the Common Stock is admitted to
trading or listed if that is the principal market for the Common Stock or, if
not listed or admitted to trading on any national securities exchange or if such
national securities exchange is not the principal market for the Common Stock,
the last sale price as reported on The Nasdaq Stock Market, Inc.'s National
Market ("Nasdaq") or its successor, if any, or if the Common Stock is not so
reported, the average of the reported bid and asked prices in the over-the-
counter market, as furnished by the National Quotation Bureau, Inc., or if such
firm is not then engaged in the business of reporting such prices, as furnished
by any similar firm then engaged in such business and selected by the Company
or, if there is no such firm, as furnished by any member of the National
Association of Securities Dealers, Inc. ("NASD") selected by the Company or, if
the Common Stock is not quoted in the over-the-counter market, the fair value
thereof determined in good faith by the Company's Board of Directors as of a
date which is within 15 days of the date as of which the determination is to be
made; and (d) the term "Trading Days" with respect to the Common Stock means (i)
if the Common Stock is quoted on Nasdaq or any similar system of automated
dissemination of quotations of securities prices, days on which trades may be
made on such system or (ii) if the Common Stock is listed or admitted for
trading on any national securities exchange, days on which such national
securities exchange is open for business.

     Section 2.4  Issuance of Common Stock. As soon as practicable after the
                  -------------------------
Date of Exercise of any Warrants, the Company shall issue, or cause its transfer
agent to issue, a

                                      -4-
<PAGE>

certificate or certificates for the number of full Warrant Shares, registered in
accordance with the instructions set forth in the Election to Purchase, together
with cash for fractional shares as provided in Section 3.10. All Warrant Shares
issued upon the exercise of any Warrants shall be validly authorized and issued,
fully paid, non-assessable, free of preemptive rights and (subject to Section
4.1 hereof) free from all taxes, liens, charges and security interests in
respect of the issuance thereof. Each person in whose name any such certificate
for Warrant Shares is issued shall be deemed for all purposes to have become the
holder of record of the Common Stock represented thereby on the Date of Exercise
of the Warrants resulting in the issuance of such shares, irrespective of the
date of issuance or delivery of such certificate for Warrant Shares.

     Section 2.5  Certificates for Unexercised Warrants. In the event that,
                  --------------------------------------
prior to the Expiration Date, a Warrant Certificate is exercised in respect of
fewer than all of the Warrant Shares issuable on such exercise, a new Warrant
Certificate representing the remaining Warrant Shares shall be issued and
delivered pursuant to the provisions hereof; provided that the Company shall not
                                             --------
be required to issue any Warrant Certificate representing any fractional Warrant
Shares.

     Section 2.6  Reservation of Shares. The Company shall at all times reserve
                  ----------------------
and keep available, free from preemptive rights, for issuance upon the exercise
of Warrants, the maximum number of its authorized but unissued shares of Common
Stock which may then be issuable upon the exercise in full of all outstanding
Warrants. The Company shall from time to time take all action which may be
necessary or appropriate so that the Warrant Shares, immediately upon their
issuance following an exercise of Warrants, will be listed or quoted, as the
case may be, on the principal securities exchanges or markets within the United
States of America, if any, on which other shares of the Common Stock are then
listed. Without limitation of Section 2.2 hereof, nothing in this Section 2.6
shall require the Company to maintain a current registration statement or
prospectus for the Warrant Shares.

     Section 2.7  No Impairment. The Company shall not by any action, including,
                  --------------
without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of the Warrants, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of the Holders against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any Warrant Shares
receivable upon the exercise of the Warrants above the amount payable therefor
upon such exercise immediately prior to such increase in par value, (b) take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and non-assessable Warrant Shares upon the
exercise of any Warrant, and (c) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under the Warrants. Notwithstanding the foregoing paragraph, the

                                      -5-
<PAGE>

Company shall not be required to issue Warrant Shares upon the exercise of any
Warrant if such issuance would result in a violation by the Company of any
applicable law.

                                  ARTICLE III
                       ADJUSTMENTS AND NOTICE PROVISIONS

     Section 3.1  Adjustment of Exercise Price. The Exercise Price and number of
                  -----------------------------
Warrant Shares issuable upon exercise of this Warrant are subject to adjustment
from time to time as set forth in this Section 3.1. Upon each such adjustment of
the Exercise Price pursuant to this Section 3.1, the Holder shall thereafter
prior to the Expiration Date be entitled to purchase, at the Exercise Price
resulting from such adjustment, the number of Warrant Shares obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares issuable upon exercise of this Warrant immediately
prior to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment.

             (a)  If the Company, at any time while this Warrant is outstanding,
(i) shall pay a stock dividend (except scheduled dividends paid on outstanding
preferred stock as of the date hereof which contain a stated dividend rate) or
otherwise make a distribution or distributions on shares of its Common Stock or
on any other class of capital stock and not the Common Stock) payable in shares
of Common Stock, (ii) subdivide or reclassify outstanding shares of Common Stock
into a larger number of shares, or (iii) combine or reclassify outstanding
shares of Common Stock into a smaller number of shares, the Exercise Price in
effect immediately prior thereto shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding before such event and the denominator shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding
after such event. Any adjustment made pursuant to this Section shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision or
combination, and shall apply to successive subdivisions and combinations.

             (b)  In case of any reclassification of the Common Stock, any
consolidation or merger of the Company with or into another person, the sale or
transfer of all or substantially all of the assets of the Company or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification, consolidation, merger, sale,
transfer or share exchange, and the Holder shall be entitled upon such event to
receive such amount of securities or property equal to the amount thereof that
would have been paid or distributed in respect of the Warrant Shares such Holder
would have received had such Holder exercised this Warrant immediately prior to
such reclassification, consolidation, merger, sale, transfer or share exchange.
The terms of any such

                                      -6-
<PAGE>

consolidation, merger, sale, transfer or share exchange shall include such terms
so as to continue to give to the Holder the right to receive the securities or
property set forth in this Section 3.1 upon any exercise following any such
reclassification, consolidation, merger, sale, transfer or share exchange.

          (c)  For the purposes of this Section 3.1, the following clauses shall
also be applicable:

               (i)  Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (A) to receive
dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

               (ii) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

          (d)  All calculations under this Section 3.1 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

          (e)  If:

               (i)    the Company shall declare a dividend (or any other
distribution) on its Common Stock; or

               (ii)   the Company shall declare a special nonrecurring cash
dividend on or a redemption of its Common Stock; or

               (iii)  the Company shall authorize the granting to all holders of
the Common Stock rights or warrants to subscribe for or purchase any shares of
capital stock of any class or of any rights; or

               (iv)   the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock of the
Company, any consolidation or merger to which the Company is a party, any sale
or transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange

                                      -7-
<PAGE>

      whereby the Common Stock is converted into other securities, cash or
      property; or

          (v)  the Company shall authorize the voluntary dissolution,
     liquidation or winding up of the affairs of the Company, then the Company
     shall cause to be mailed to each Holder at their last addresses as they
     shall appear upon the Warrant Register, at least 30 calendar days prior to
     the applicable record or effective date hereinafter specified, a notice
     stating (x) the date on which a record is to be taken for the purpose of
     such dividend, distribution, redemption, rights or warrants, or if a record
     is not to be taken, the date as of which the holders of Common Stock of
     record to be entitled to such dividend, distributions, redemption, rights
     or warrants are to be determined or (y) the date on which such
     reclassification, consolidation, merger, sale, transfer or share exchange
     is expected to become effective or close, and the date as of which it is
     expected that holders of Common Stock of record shall be entitled to
     exchange their shares of Common Stock for securities, cash or other
     property deliverable upon such reclassification, consolidation, merger,
     sale, transfer, share exchange, dissolution, liquidation or winding up;
     provided, however, that the failure to mail such notice or any defect
     therein or in the mailing thereof shall not affect the validity of the
     corporate action required to be specified in such notice.

     Section 3.2  Certificate of Adjustments. Whenever any adjustment is to be
                  ---------------------------
made pursuant to this Article III, the Company shall prepare a certificate
executed by the Chief Financial Officer of the Company, setting forth such
adjustments to be mailed to each Holder at least fifteen (15) days prior
thereto, such notice to include in reasonable detail (a) the events
precipitating the adjustment, (b) the computation of any adjustments, and (c)
the Exercise Price and the number of shares or the securities or other property
purchasable upon exercise of each Warrant after giving effect to such
adjustment.

     Section 3.3  Warrant Certificate Amendments. Irrespective of any
                  -------------------------------
adjustments pursuant to this Article III, Warrant Certificates theretofore or
thereafter issued need not be amended or replaced, but certificates thereafter
issued shall bear an appropriate legend or other notice of any adjustments;
provided the Company may, at its option, issue new Warrant Certificates
--------
evidencing Warrants in such form as may be approved by its Board of Directors to
reflect any adjustment in the Exercise Price and number of Warrant Shares
purchasable under the Warrants.

     Section 3.4  Fractional Shares. The Company shall not be required upon the
                  ------------------
exercise of any Warrant to issue fractional Warrant Shares which may result from
adjustments in accordance with this Article III to the Exercise Price or number
of Warrant Shares purchasable under each Warrant. If more than one Warrant is
exercised at one time by the same Holder, the number of full Warrant Shares
which shall be issuable upon the exercise thereof shall be computed based on the
aggregate number of Warrant Shares purchasable upon exercise of such Warrants.
With respect to any final fraction of a share called for upon the exercise of
any Warrant or Warrants, the Company shall pay an amount in cash to the Holder
of the Warrants in

                                      -8-
<PAGE>

respect of such final fraction in an amount equal to the Fair Market Value of a
share of Common Stock as of the Date of Exercise of such Warrants, multiplied by
such fraction. All calculations under this Section 3.4 shall be made to the
nearest hundredth of a share.
